## tg-holy-bot
Телеграммный бот для канала с праздниками. Раз в сутки забирает список праздников с к сайта celebratoday.com и
показывает его на канальчике в телеграме.
## Как это собрать?
Понадобится компилятор go версии 1.25.3 или более новый.
Сам процесс сборки простой, достаточно запустить make или gmake, в зависимости от платформы:
```bash
make
```
и через некоторое время мы получаем бинарник **tg-holy-bot**. Это и есть наше приложение.
### Как это запустить?
Приложение тестировалось на alpine linux x86_64 3.16, но должно работать на любом (более свежем) linux-е.
Предполагается, что конфиг написан в формате [human json](https://hjson.github.io), который допускает коментарии и
некоторые другие вольности в форматировании json-а. Конфиг ищется последовательно по следующим путям по принципу "кто
первый того и тапки":
```
~/.tg-holy-bot.json
/etc/tg-holy-bot.json
data/config.json
```
В каталоге contrib находится скрипт для alpine linux, системы инициализации openrc. Этот скрипт достаточно положить в
**/etc/init.d/tg-holy-bot**. После чего скопировать бинарник в каталог **/var/lib/tg-holy-bot**, положить
конфиг в одну из дефолтных локаций (тестировалась **/var/lib/tg-holy-bot/data/config.json**) и после этого сервис
запускается командой:
```bash
service tg-holy-bot start
```
В автозагрузку его можно прописать через команду:
```bash
rc-update add tg-holy-bot default
```
### Nota Bene
Go не поддерживает системный вызов fork() из-за чего демонизация программ на гошке средствами самой гошки - это в
некотором роде проблема. Решается она с помощью утилиты [daemonize](https://github.com/bmc/daemonize).
Соответствено, если для запуска этой программы предполагается использовать возможности демонизации, то можно
воспользоваться этой программой.
В alpine linux есть средства openrc для супервайзинга foreground-сервисов.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
echotron Copyright (C) 2019 Nicolò Santamaria
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read

| :------: |
**Echotron** is an elegant and concurrent library for the Telegram bot API in Go.
Fetch with
```bash
go get github.com/NicoNex/echotron/v3
```
## Example
### Simplest implementations
#### Long polling
```golang
package main
import "github.com/NicoNex/echotron/v3"
const token = "MY TELEGRAM TOKEN"
func main() {
api := echotron.NewAPI(token)
for u := range echotron.PollingUpdates(token) {
if u.Message.Text == "/start" {
api.SendMessage("Hello world", u.ChatID(), nil)
}
}
}
```
#### Webhook
```golang
package main
import "github.com/NicoNex/echotron/v3"
const token = "MY TELEGRAM TOKEN"
func main() {
api := echotron.NewAPI(token)
for u := range echotron.WebhookUpdates("https://example.com:443/my_token", token) {
if u.Message.Text == "/start" {
api.SendMessage("Hello world", u.ChatID(), nil)
}
}
}
```
For more scalable and recommended implementations see the other examples.
### Long Polling
```golang
package main
import (
"log"
"time"
"github.com/NicoNex/echotron/v3"
)
// Struct useful for managing internal states in your bot, but it could be of
// any type such as `type bot int64` if you only need to store the chatID.
type bot struct {
chatID int64
echotron.API
}
const token = "MY TELEGRAM TOKEN"
// This function needs to be of type 'echotron.NewBotFn' and is called by
// the echotron dispatcher upon any new message from a chatID that has never
// interacted with the bot before.
// This means that echotron keeps one instance of the echotron.Bot implementation
// for each chat where the bot is used.
func newBot(chatID int64) echotron.Bot {
return &bot{
chatID,
echotron.NewAPI(token),
}
}
// This method is needed to implement the echotron.Bot interface.
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatID, nil)
}
}
func main() {
// This is the entry point of echotron library.
dsp := echotron.NewDispatcher(token, newBot)
for {
log.Println(dsp.Poll())
// In case of connection issues wait 5 seconds before trying to reconnect.
time.Sleep(5 * time.Second)
}
}
```
## Design
**Echotron** makes a new instance of the struct bot for each open chat with a Telegram user, channel or group.
This allows to:
- safely call the `Update(*echotron.Update)` method concurrently
- give to the user a convenient way to manage the bot internal states across all the chats
- make sure that, even if one instance of the bot is deadlocked, the other ones keep running just fine, making the bot work for other users without any issues and/or slowdowns.
Please note that the the aforementioned behaviour is dictated by the `echotron.Dispatcher` object whose usage is not mandatory and for special needs can be ignored and implemented in different ways still keeping all the methods in the `echotron.API` object.
**Echotron** is designed to be as similar to the official [Telegram API](https://core.telegram.org/bots/api) as possible, but there are some things to take into account before starting to work with this library.
- The methods have the exact same name, but with a capital first letter, since in Go methods have to start with a capital letter to be exported.
_Example: `sendMessage` becomes `SendMessage`_
- The order of the parameters in some methods is different than in the official Telegram API, so refer to the [docs](https://pkg.go.dev/github.com/NicoNex/echotron/v3) for the correct one.
- The only `chat_id` (or, in this case, `chatID`) type supported is `int64`, instead of the "Integer or String" requirement of the official API. That's because numeric IDs can't change in any way, which isn't the case with text-based usernames.
- In some methods, you might find a `InputFile` type parameter. [`InputFile`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#InputFile) is a struct with unexported fields, since only three combination of fields are valid, which can be obtained through the methods [`NewInputFileID`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#NewInputFileID), [`NewInputFilePath`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#NewInputFilePath) and [`NewInputFileBytes`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#NewInputFileBytes).
- In some methods, you might find a `MessageIDOptions` type parameter. [`MessageIDOptions`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#MessageIDOptions) is another struct with unexported fields, since only two combination of field are valid, which can be obtained through the methods [`NewMessageID`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#NewMessageID) and [`NewInlineMessageID`](https://pkg.go.dev/github.com/NicoNex/echotron/v3#NewInlineMessageID).
- Optional parameters can be added by passing the correct struct to each method that might request optional parameters. If you don't want to pass any optional parameter, `nil` is more than enough. Refer to the [docs](https://pkg.go.dev/github.com/NicoNex/echotron/v3) to check for each method's optional parameters struct: it's the type of the `opts` parameter.
- Some parameters are hardcoded to avoid putting random stuff which isn't recognized by the Telegram API. Some notable examples are [`ParseMode`](https://github.com/NicoNex/echotron/blob/master/options.go#L21), [`ChatAction`](https://github.com/NicoNex/echotron/blob/master/options.go#L54) and [`InlineQueryType`](https://github.com/NicoNex/echotron/blob/master/inline.go#L27). For a full list of custom hardcoded parameters, refer to the [docs](https://pkg.go.dev/github.com/NicoNex/echotron/v3) for each custom type: by clicking on the type's name, you'll get the source which contains the possible values for that type.
## Additional examples
### Functional approach to state management
```golang
package main
import (
"log"
"strings"
"github.com/NicoNex/echotron/v3"
)
// Recursive type definition of the bot state function.
type stateFn func(*echotron.Update) stateFn
type bot struct {
chatID int64
state stateFn
name string
echotron.API
}
const token = "MY TELEGRAM TOKEN"
func newBot(chatID int64) echotron.Bot {
bot := &bot{
chatID: chatID,
API: echotron.NewAPI(token),
}
// We set the default state to the bot.handleMessage method.
bot.state = bot.handleMessage
return bot
}
func (b *bot) Update(update *echotron.Update) {
// Here we execute the current state and set the next one.
b.state = b.state(update)
}
func (b *bot) handleMessage(update *echotron.Update) stateFn {
if strings.HasPrefix(update.Message.Text, "/set_name") {
b.SendMessage("Send me my new name!", b.chatID, nil)
// Here we return b.handleName since next time we receive a message it
// will be the new name.
return b.handleName
}
return b.handleMessage
}
func (b *bot) handleName(update *echotron.Update) stateFn {
b.name = update.Message.Text
b.SendMessage(fmt.Sprintf("My new name is %q", b.name), b.chatID, nil)
// Here we return b.handleMessage since the next time we receive a message
// it will be handled in the default way.
return b.handleMessage
}
func main() {
dsp := echotron.NewDispatcher(token, newBot)
log.Println(dsp.Poll())
}
```
### Self destruction for lower memory footprint
```golang
package main
import (
"log"
"time"
"github.com/NicoNex/echotron/v3"
)
type bot struct {
chatID int64
echotron.API
}
const token = "MY TELEGRAM TOKEN"
var dsp *echotron.Dispatcher
func newBot(chatID int64) echotron.Bot {
bot := &bot{
chatID,
echotron.NewAPI(token),
}
go bot.selfDestruct(time.After(time.Hour))
return bot
}
func (b *bot) selfDestruct(timech <-chan time.Time) {
<-timech
b.SendMessage("goodbye", b.chatID, nil)
dsp.DelSession(b.chatID)
}
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatID, nil)
}
}
func main() {
dsp = echotron.NewDispatcher(token, newBot)
log.Println(dsp.Poll())
}
```
### Webhook
```golang
package main
import "github.com/NicoNex/echotron/v3"
type bot struct {
chatID int64
echotron.API
}
const token = "MY TELEGRAM TOKEN"
func newBot(chatID int64) echotron.Bot {
return &bot{
chatID,
echotron.NewAPI(token),
}
}
func (b *bot) Update(update *echotron.Update) {
if update.Message.Text == "/start" {
b.SendMessage("Hello world", b.chatID, nil)
}
}
func main() {
dsp := echotron.NewDispatcher(token, newBot)
dsp.ListenWebhook("https://example.com:443/my_bot_token")
}
```
### Webhook with a custom http.Server
This is an example for a custom http.Server which handles your own specified routes
and also the webhook route which is specified by ListenWebhook.
```golang
package main
import (
"github.com/NicoNex/echotron/v3"
"context"
"log"
"net/http"
"os"
"os/signal"
"syscall"
)
type bot struct {
chatID int64
echotron.API
}
const token = "MY TELEGRAM TOKEN"

# Requests [![GoDoc](https://godoc.org/github.com/carlmjohnson/requests?status.svg)](https://godoc.org/github.com/carlmjohnson/requests) [![Go Report Card](https://goreportcard.com/badge/github.com/carlmjohnson/requests)](https://goreportcard.com/report/github.com/carlmjohnson/requests) [![Coverage Status](https://coveralls.io/repos/github/earthboundkid/requests/badge.svg)](https://coveralls.io/github/earthboundkid/requests) [![Mentioned in Awesome Go](https://awesome.re/mentioned-badge.svg)](https://github.com/avelino/awesome-go)
![Requests logo](https://github.com/earthboundkid/requests/assets/222245/e59a9f82-c6c7-46d8-96b2-ce2f7dd58dce)
## _HTTP requests for Gophers._
**The problem**: Go's net/http is powerful and versatile, but using it correctly for client requests can be extremely verbose.
**The solution**: The requests.Builder type is a convenient way to build, send, and handle HTTP requests. Builder has a fluent API with methods returning a pointer to the same struct, which allows for declaratively describing a request by method chaining.
Requests also comes with tools for building custom http transports, include a request recorder and replayer for testing.
*[See this note on the canonical project URL.](https://gist.github.com/earthboundkid/8915002ae0e531cecdfc58bc6453ac80)*
## Features
- Simplifies HTTP client usage compared to net/http
- Can't forget to close response body
- Checks status codes by default
- Supports context.Context
- JSON serialization and deserialization helpers
- Easily manipulate URLs and query parameters
- Request recording and replaying for tests
- Customizable transports and validators that are compatible with the standard library and third party libraries
- No third party dependencies
- Good test coverage
## Examples
### Simple GET into a string
<table>
<thead>
<tr>
<th><strong>code with net/http</strong></th>
<th><strong>code with requests</strong></th>
</tr>
</thead>
<tbody>
<tr>
<td>
```go
req, err := http.NewRequestWithContext(ctx,
http.MethodGet, "http://example.com", nil)
if err != nil {
// ...
}
res, err := http.DefaultClient.Do(req)
if err != nil {
// ...
}
defer res.Body.Close()
b, err := io.ReadAll(res.Body)
if err != nil {
// ...
}
s := string(b)
```
</td>
<td>
```go
var s string
err := requests.
URL("http://example.com").
ToString(&s).
Fetch(ctx)
```
</td>
</tr>
<tr><td>11+ lines</td><td>5 lines</td></tr>
</tbody>
</table>
### POST a raw body
<table>
<thead>
<tr>
<th><strong>code with net/http</strong></th>
<th><strong>code with requests</strong></th>
</tr>
</thead>
<tbody>
<tr>
<td>
```go
body := bytes.NewReader(([]byte(`hello, world`))
req, err := http.NewRequestWithContext(ctx, http.MethodPost,
"https://postman-echo.com/post", body)
if err != nil {
// ...
}
req.Header.Set("Content-Type", "text/plain")
res, err := http.DefaultClient.Do(req)
if err != nil {
// ...
}
defer res.Body.Close()
_, err := io.ReadAll(res.Body)
if err != nil {
// ...
}
```
</td>
<td>
```go
err := requests.
URL("https://postman-echo.com/post").
BodyBytes([]byte(`hello, world`)).
ContentType("text/plain").
Fetch(ctx)
```
</td>
</tr>
<tr><td>12+ lines</td><td>5 lines</td></tr></tbody></table>
### GET a JSON object
<table>
<thead>
<tr>
<th><strong>code with net/http</strong></th>
<th><strong>code with requests</strong></th>
</tr>
</thead>
<tbody>
<tr>
<td>
```go
var post placeholder
u, err := url.Parse("https://jsonplaceholder.typicode.com")
if err != nil {
// ...
}
u.Path = fmt.Sprintf("/posts/%d", 1)
req, err := http.NewRequestWithContext(ctx,
http.MethodGet, u.String(), nil)
if err != nil {
// ...
}
res, err := http.DefaultClient.Do(req)
if err != nil {
// ...
}
defer res.Body.Close()
b, err := io.ReadAll(res.Body)
if err != nil {
// ...
}
err := json.Unmarshal(b, &post)
if err != nil {
// ...
}
```
</td><td>
```go
var post placeholder
err := requests.
URL("https://jsonplaceholder.typicode.com").
Pathf("/posts/%d", 1).
ToJSON(&post).
Fetch(ctx)
```
</td>
</tr>
<tr><td>18+ lines</td><td>7 lines</td></tr></tbody></table>
### POST a JSON object and parse the response
```go
var res placeholder
req := placeholder{
Title: "foo",
Body: "baz",
UserID: 1,
}
err := requests.
URL("/posts").
Host("jsonplaceholder.typicode.com").
BodyJSON(&req).
ToJSON(&res).
Fetch(ctx)
// net/http equivalent left as an exercise for the reader
```
### Set custom headers for a request
```go
// Set headers
var headers postman
err := requests.
URL("https://postman-echo.com/get").
UserAgent("bond/james-bond").
ContentType("secret").
Header("martini", "shaken").
Fetch(ctx)
```
### Easily manipulate URLs and query parameters
```go
u, err := requests.
URL("https://prod.example.com/get?a=1&b=2").
Hostf("%s.example.com", "dev1").
Param("b", "3").
ParamInt("c", 4).
URL()
if err != nil { /* ... */ }
fmt.Println(u.String()) // https://dev1.example.com/get?a=1&b=3&c=4
```
### Record and replay responses
```go
// record a request to the file system
var s1, s2 string
err := requests.URL("http://example.com").
Transport(reqtest.Record(nil, "somedir")).
ToString(&s1).
Fetch(ctx)
check(err)
// now replay the request in tests
err = requests.URL("http://example.com").
Transport(reqtest.Replay("somedir")).
ToString(&s2).
Fetch(ctx)
check(err)
assert(s1 == s2) // true
```
## FAQs
[See wiki](https://github.com/earthboundkid/requests/wiki) for more details.
### Why not just use the standard library HTTP client?
Brad Fitzpatrick, long time maintainer of the net/http package, [wrote an extensive list of problems with the standard library HTTP client](https://github.com/bradfitz/exp-httpclient/blob/master/problems.md). His four main points (ignoring issues that can't be resolved by a wrapper around the standard library) are:
> - Too easy to not call Response.Body.Close.
> - Too easy to not check return status codes
> - Context support is oddly bolted on
> - Proper usage is too many lines of boilerplate
Requests solves these issues by always closing the response body, checking status codes by default, always requiring a `context.Context`, and simplifying the boilerplate with a descriptive UI based on fluent method chaining.
### Why requests and not some other helper library?
There are two major flaws in other libraries as I see it. One is that in other libraries support for `context.Context` tends to be bolted on if it exists at all. Two, many hide the underlying `http.Client` in such a way that it is difficult or impossible to replace or mock out. Beyond that, I believe that none have achieved the same core simplicity that the requests library has.
### How do I just get some JSON?
```go
var data SomeDataType
err := requests.
URL("https://example.com/my-json").
ToJSON(&data).
Fetch(ctx)
```
### How do I post JSON and read the response JSON?
```go
body := MyRequestType{}
var resp MyResponseType
err := requests.
URL("https://example.com/my-json").
BodyJSON(&body).
ToJSON(&resp).
Fetch(ctx)
```
### How do I just save a file to disk?
It depends on exactly what you need in terms of file atomicity and buffering, but this will work for most cases:
```go
err := requests.
URL("http://example.com").
ToFile("myfile.txt").
Fetch(ctx)
```
For more advanced use case, use `ToWriter`.
### How do I save a response to a string?
```go
var s string
err := requests.
URL("http://example.com").
ToString(&s).
Fetch(ctx)
```
### How do I validate the response status?
By default, if no other validators are added to a builder, requests will check that the response is in the 2XX range. If you add another validator, you can add `builder.CheckStatus(200)` or `builder.AddValidator(requests.DefaultValidator)` to the validation stack.
To disable all response validation, run `builder.AddValidator(nil)`.

// Builder is a convenient way to build, send, and handle HTTP requests.
// Builder has a fluent API with methods returning a pointer to the same
// struct, which allows for declaratively describing a request by method chaining.
//
// Builder can build a url.URL,
// build an http.Request,
// or handle a full http.Client request and response with validation.
//
// # Build a url.URL with Builder.URL
//
// Set the base URL by creating a new Builder with [requests.URL]
// or by calling [Builder.BaseURL]
// then customize it with
// [Builder.Scheme], [Builder.Host], [Builder.Hostf], [Builder.Path],
// [Builder.Pathf], [Builder.Param], and [Builder.ParamInt].
// [Builder.ParamOptional] can be used to add a query parameter
// only if it has not been otherwise set.
//
// # Build an http.Request with Builder.Request
//
// Set the method for a request with [Builder.Method]
// or use the [Builder.Delete], [Builder.Head], [Builder.Patch], [Builder.Post], and [Builder.Put] methods.
// By default, requests without a body are GET,
// and those with a body are POST.
//
// Set headers with [Builder.Header]
// or set conventional header keys with
// [Builder.Accept], [Builder.BasicAuth], [Builder.Bearer], [Builder.CacheControl],
// [Builder.ContentType], [Builder.Cookie], and [Builder.UserAgent].
// [Builder.HeaderOptional] can be used to add a header
// only if it has not been otherwise set.
//
// Set the body of the request, if any, with [Builder.Body]
// or use built in [Builder.BodyBytes], [Builder.BodyFile], [Builder.BodyForm],
// [Builder.BodyJSON], [Builder.BodyReader], or [Builder.BodyWriter].
//
// # Handle a request and response with Builder.Do or Builder.Fetch
//
// Set the http.Client to use for a request with [Builder.Client]
// and/or set an http.RoundTripper with [Builder.Transport].
//
// Add a response validator to the Builder with [Builder.AddValidator]
// or use the built in [Builder.CheckStatus], [Builder.CheckContentType],
// [Builder.CheckPeek], [Builder.CopyHeaders], and [Builder.ErrorJSON].
// If no validator has been added, Builder will use [DefaultValidator].
//
// Set a handler for a response with [Builder.Handle]
// or use the built in [Builder.ToHeaders], [Builder.ToJSON], [Builder.ToString],
// [Builder.ToBytesBuffer], or [Builder.ToWriter].
//
// [Builder.Fetch] creates an http.Request with [Builder.Request]
// and validates and handles it with [Builder.Do].
//
// # Other methods
//
// [Builder.Config] can be used to set several options on a Builder at once.
// [New] creates a new Builder and applies [Config] options to it.
//
// In many cases, it will be possible to set most options for an API endpoint
// in a Builder at the package or struct level

}
```
The Go implementation of Hjson is based on [hjson-js](https://github.com/hjson/hjson-js). For other platforms see [hjson.github.io](https://hjson.github.io).
# Install
Make sure you have a working Go environment. See the [install instructions](http://golang.org/doc/install.html).
1. Get the sources
```bash
$ go get -u github.com/hjson/hjson-go
```
2. Build the **hjson-cli** commandline tool (optional)
```bash
$ cd $(go env GOPATH)/src/github.com/hjson/hjson-go/hjson-cli && go install
$ hjson-cli --version
```
# Usage as command line tool
```
usage: hjson-cli [OPTIONS] [INPUT]
hjson can be used to convert JSON from/to Hjson.
hjson will read the given JSON/Hjson input file or read from stdin.
Options:
-allowMinusZero
Allow -0.
-bracesSameLine
Print braces on the same line.
-c Output as JSON.
-h Show this screen.
-indentBy string
The indent string. (default " ")
-j Output as formatted JSON.
-omitRootBraces
Omit braces at the root.
-quoteAlways
Always quote string values.
```
Sample:
- run `hjson-cli test.json > test.hjson` to convert to Hjson
- run `hjson-cli -j test.hjson > test.json` to convert to JSON
# Usage as a GO library
```go
package main
import (
"github.com/hjson/hjson-go"
"fmt"
)
func main() {
// Now let's look at decoding Hjson data into Go
// values.
sampleText := []byte(`
{
# specify rate in requests/second
rate: 1000
array:
[
foo
bar
]
}`)
// We need to provide a variable where Hjson
// can put the decoded data.
var dat map[string]interface{}
// Decode and a check for errors.
if err := hjson.Unmarshal(sampleText, &dat); err != nil {
panic(err)
}
fmt.Println(dat)
// In order to use the values in the decoded map,
// we'll need to cast them to their appropriate type.
rate := dat["rate"].(float64)
fmt.Println(rate)
array := dat["array"].([]interface{})
str1 := array[0].(string)
fmt.Println(str1)
// To encode to Hjson with default options:
sampleMap := map[string]int{"apple": 5, "lettuce": 7}
hjson, _ := hjson.Marshal(sampleMap)
// this is short for:
// options := hjson.DefaultOptions()
// hjson, _ := hjson.MarshalWithOptions(sampleMap, options)
fmt.Println(string(hjson))
}
```
If you prefer, you can also unmarshal to Go objects by converting to JSON:
```go
package main
import (
"github.com/hjson/hjson-go"
"encoding/json"
"fmt"
)
type Sample struct {
Rate int
Array []string
}
func main() {
sampleText := []byte(`
{
# specify rate in requests/second
rate: 1000
array:
[
foo
bar
]
}`)
// read Hjson
var dat map[string]interface{}
hjson.Unmarshal(sampleText, &dat)
// convert to JSON
b, _ := json.Marshal(dat)
// unmarshal
var sample Sample
json.Unmarshal(b, &sample)
fmt.Println(sample.Rate)
fmt.Println(sample.Array)
}
```

# cron
Cron V3 has been released!
To download the specific tagged release, run:
go get github.com/robfig/cron/v3@v3.0.0
Import it in your program as:
import "github.com/robfig/cron/v3"
It requires Go 1.11 or later due to usage of Go Modules.
Refer to the documentation here:
http://godoc.org/github.com/robfig/cron
The rest of this document describes the the advances in v3 and a list of
breaking changes for users that wish to upgrade from an earlier version.
## Upgrading to v3 (June 2019)
cron v3 is a major upgrade to the library that addresses all outstanding bugs,
feature requests, and rough edges. It is based on a merge of master which
contains various fixes to issues found over the years and the v2 branch which
contains some backwards-incompatible features like the ability to remove cron
jobs. In addition, v3 adds support for Go Modules, cleans up rough edges like
the timezone support, and fixes a number of bugs.
New features:
- Support for Go modules. Callers must now import this library as
`github.com/robfig/cron/v3`, instead of `gopkg.in/...`
- Fixed bugs:
- 0f01e6b parser: fix combining of Dow and Dom (#70)
- dbf3220 adjust times when rolling the clock forward to handle non-existent midnight (#157)
- eeecf15 spec_test.go: ensure an error is returned on 0 increment (#144)
- 70971dc cron.Entries(): update request for snapshot to include a reply channel (#97)
- 1cba5e6 cron: fix: removing a job causes the next scheduled job to run too late (#206)
- Standard cron spec parsing by default (first field is "minute"), with an easy
way to opt into the seconds field (quartz-compatible). Although, note that the
year field (optional in Quartz) is not supported.
- Extensible, key/value logging via an interface that complies with
the https://github.com/go-logr/logr project.
- The new Chain & JobWrapper types allow you to install "interceptors" to add
cross-cutting behavior like the following:
- Recover any panics from jobs
- Delay a job's execution if the previous run hasn't completed yet
- Skip a job's execution if the previous run hasn't completed yet
- Log each job's invocations
- Notification when jobs are completed
It is backwards incompatible with both v1 and v2. These updates are required:
- The v1 branch accepted an optional seconds field at the beginning of the cron
spec. This is non-standard and has led to a lot of confusion. The new default
parser conforms to the standard as described by [the Cron wikipedia page].
UPDATING: To retain the old behavior, construct your Cron with a custom
parser:
// Seconds field, required
cron.New(cron.WithSeconds())
// Seconds field, optional
cron.New(
cron.WithParser(
cron.SecondOptional | cron.Minute | cron.Hour | cron.Dom | cron.Month | cron.Dow | cron.Descriptor))
- The Cron type now accepts functional options on construction rather than the
previous ad-hoc behavior modification mechanisms (setting a field, calling a setter).
UPDATING: Code that sets Cron.ErrorLogger or calls Cron.SetLocation must be
updated to provide those values on construction.
- CRON_TZ is now the recommended way to specify the timezone of a single
schedule, which is sanctioned by the specification. The legacy "TZ=" prefix
will continue to be supported since it is unambiguous and easy to do so.
UPDATING: No update is required.
- By default, cron will no longer recover panics in jobs that it runs.
Recovering can be surprising (see issue #192) and seems to be at odds with
typical behavior of libraries. Relatedly, the `cron.WithPanicLogger` option
has been removed to accommodate the more general JobWrapper type.
UPDATING: To opt into panic recovery and configure the panic logger:
cron.New(cron.WithChain(
cron.Recover(logger), // or use cron.DefaultLogger
))
- In adding support for https://github.com/go-logr/logr, `cron.WithVerboseLogger` was
removed, since it is duplicative with the leveled logging.
UPDATING: Callers should use `WithLogger` and specify a logger that does not
discard `Info` logs. For convenience, one is provided that wraps `*log.Logger`:
cron.New(
cron.WithLogger(cron.VerbosePrintfLogger(logger)))
### Background - Cron spec format
There are two cron spec formats in common usage:
- The "standard" cron format, described on [the Cron wikipedia page] and used by
the cron Linux system utility.
- The cron format used by [the Quartz Scheduler], commonly used for scheduled
jobs in Java software
[the Cron wikipedia page]: https://en.wikipedia.org/wiki/Cron
[the Quartz Scheduler]: http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/tutorial-lesson-06.html
The original version of this package included an optional "seconds" field, which
made it incompatible with both of these formats. Now, the "standard" format is
the default format accepted, and the Quartz format is opt-in.

/*
Package cron implements a cron spec parser and job runner.
Installation
To download the specific tagged release, run:
go get github.com/robfig/cron/v3@v3.0.0
Import it in your program as:
import "github.com/robfig/cron/v3"
It requires Go 1.11 or later due to usage of Go Modules.
Usage
Callers may register Funcs to be invoked on a given schedule. Cron will run
them in their own goroutines.
c := cron.New()
c.AddFunc("30 * * * *", func() { fmt.Println("Every hour on the half hour") })
c.AddFunc("30 3-6,20-23 * * *", func() { fmt.Println(".. in the range 3-6am, 8-11pm") })
c.AddFunc("CRON_TZ=Asia/Tokyo 30 04 * * *", func() { fmt.Println("Runs at 04:30 Tokyo time every day") })
c.AddFunc("@hourly", func() { fmt.Println("Every hour, starting an hour from now") })
c.AddFunc("@every 1h30m", func() { fmt.Println("Every hour thirty, starting an hour thirty from now") })
c.Start()
..
// Funcs are invoked in their own goroutine, asynchronously.
...
// Funcs may also be added to a running Cron
c.AddFunc("@daily", func() { fmt.Println("Every day") })
..
// Inspect the cron job entries' next and previous run times.
inspect(c.Entries())
..
c.Stop() // Stop the scheduler (does not stop any jobs already running).
CRON Expression Format
A cron expression represents a set of times, using 5 space-separated fields.
Field name | Mandatory? | Allowed values | Allowed special characters
---------- | ---------- | -------------- | --------------------------
Minutes | Yes | 0-59 | * / , -
Hours | Yes | 0-23 | * / , -
Day of month | Yes | 1-31 | * / , - ?
Month | Yes | 1-12 or JAN-DEC | * / , -
Day of week | Yes | 0-6 or SUN-SAT | * / , - ?
Month and Day-of-week field values are case insensitive. "SUN", "Sun", and
"sun" are equally accepted.
The specific interpretation of the format is based on the Cron Wikipedia page:
https://en.wikipedia.org/wiki/Cron
Alternative Formats
Alternative Cron expression formats support other fields like seconds. You can
implement that by creating a custom Parser as follows.
cron.New(
cron.WithParser(
cron.NewParser(
cron.SecondOptional | cron.Minute | cron.Hour | cron.Dom | cron.Month | cron.Dow | cron.Descriptor)))
Since adding Seconds is the most common modification to the standard cron spec,
cron provides a builtin function to do that, which is equivalent to the custom
parser you saw earlier, except that its seconds field is REQUIRED:
cron.New(cron.WithSeconds())
That emulates Quartz, the most popular alternative Cron schedule format:
http://www.quartz-scheduler.org/documentation/quartz-2.x/tutorials/crontrigger.html
Special Characters
Asterisk ( * )
The asterisk indicates that the cron expression will match for all values of the
field; e.g., using an asterisk in the 5th field (month) would indicate every
month.
Slash ( / )
Slashes are used to describe increments of ranges. For example 3-59/15 in the
1st field (minutes) would indicate the 3rd minute of the hour and every 15
minutes thereafter. The form "*\/..." is equivalent to the form "first-last/...",
that is, an increment over the largest possible range of the field. The form
"N/..." is accepted as meaning "N-MAX/...", that is, starting at N, use the
increment until the end of that specific range. It does not wrap around.
Comma ( , )
Commas are used to separate items of a list. For example, using "MON,WED,FRI" in
the 5th field (day of week) would mean Mondays, Wednesdays and Fridays.
Hyphen ( - )
Hyphens are used to define ranges. For example, 9-17 would indicate every
hour between 9am and 5pm inclusive.
Question mark ( ? )
Question mark may be used instead of '*' for leaving either day-of-month or
day-of-week blank.
Predefined schedules
You may use one of several pre-defined schedules in place of a cron expression.
Entry | Description | Equivalent To
----- | ----------- | -------------
@yearly (or @annually) | Run once a year, midnight, Jan. 1st | 0 0 1 1 *
@monthly | Run once a month, midnight, first of month | 0 0 1 * *
@weekly | Run once a week, midnight between Sat/Sun | 0 0 * * 0
@daily (or @midnight) | Run once a day, midnight | 0 0 * * *
@hourly | Run once an hour, beginning of hour | 0 * * * *
Intervals
You may also schedule a job to execute at fixed intervals, starting at the time it's added
or cron is run. This is supported by formatting the cron spec like this:
@every <duration>
where "duration" is a string accepted by time.ParseDuration
(http://golang.org/pkg/time/#ParseDuration).
For example, "@every 1h30m10s" would indicate a schedule that activates after
1 hour, 30 minutes, 10 seconds, and then every interval after that.
Note: The interval does not take the job runtime into account. For example,
if a job takes 3 minutes to run, and it is scheduled to run every 5 minutes,
it will have only 2 minutes of idle time between each run.
Time zones
By default, all interpretation and scheduling is done in the machine's local
time zone (time.Local). You can specify a different time zone on construction:
cron.New(
cron.WithLocation(time.UTC))
Individual cron schedules may also override the time zone they are to be
interpreted in by providing an additional space-separated field at the beginning
of the cron spec, of the form "CRON_TZ=Asia/Tokyo".
For example:
# Runs at 6am in time.Local
cron.New().AddFunc("0 6 * * ?", ...)
# Runs at 6am in America/New_York
nyc, _ := time.LoadLocation("America/New_York")
c := cron.New(cron.WithLocation(nyc))
c.AddFunc("0 6 * * ?", ...)
# Runs at 6am in Asia/Tokyo
cron.New().AddFunc("CRON_TZ=Asia/Tokyo 0 6 * * ?", ...)
# Runs at 6am in Asia/Tokyo
c := cron.New(cron.WithLocation(nyc))
c.SetLocation("America/New_York")
c.AddFunc("CRON_TZ=Asia/Tokyo 0 6 * * ?", ...)
The prefix "TZ=(TIME ZONE)" is also supported for legacy compatibility.
Be aware that jobs scheduled during daylight-savings leap-ahead transitions will
not be run!
Job Wrappers
A Cron runner may be configured with a chain of job wrappers to add
cross-cutting functionality to all submitted jobs. For example, they may be used
to achieve the following effects:
- Recover any panics from jobs (activated by default)
- Delay a job's execution if the previous run hasn't completed yet
- Skip a job's execution if the previous run hasn't completed yet
- Log each job's invocations
Install wrappers for all jobs added to a cron using the `cron.WithChain` option:
cron.New(cron.WithChain(
cron.SkipIfStillRunning(logger),
))
Install wrappers for individual jobs by explicitly wrapping them:
job = cron.NewChain(
cron.SkipIfStillRunning(logger),
).Then(job)
Thread safety
Since the Cron service runs concurrently with the calling code, some amount of
care must be taken to ensure proper synchronization.
All cron methods are designed to be correctly synchronized as long as the caller
ensures that invocations have a clear happens-before ordering between them.
Logging
Cron defines a Logger interface that is a subset of the one defined in
github.com/go-logr/logr. It has two logging levels (Info and Error), and
parameters are key/value pairs. This makes it possible for cron logging to plug
into structured logging systems. An adapter, [Verbose]PrintfLogger, is provided
to wrap the standard library *log.Logger.
For additional insight into Cron operations, verbose logging may be activated
which will record job runs, scheduling decisions, and added or removed jobs.
Activate it with a one-off logger as follows:
cron.New(
cron.WithLogger(
cron.VerbosePrintfLogger(log.New(os.Stdout, "cron: ", log.LstdFlags))))
Implementation
Cron entries are stored in an array, sorted by their next activation time. Cron
sleeps until the next job is due to be run.
Upon waking:
- it runs each entry that is active on that second
- it calculates the next run times for the jobs that were run
- it re-sorts the array of entries by next activation time.
- it goes to sleep until the soonest job.

Package html implements an HTML5-compliant tokenizer and parser.
Tokenization is done by creating a Tokenizer for an io.Reader r. It is the
caller's responsibility to ensure that r provides UTF-8 encoded HTML.
z := html.NewTokenizer(r)
Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(),
which parses the next token and returns its type, or an error:
for {
tt := z.Next()
if tt == html.ErrorToken {
// ...
return ...
}
// Process the current token.
}
There are two APIs for retrieving the current token. The high-level API is to
call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs
allow optionally calling Raw after Next but before Token, Text, TagName, or
TagAttr. In EBNF notation, the valid call sequence per token is:
Next {Raw} [ Token | Text | TagName {TagAttr} ]
Token returns an independent data structure that completely describes a token.
Entities (such as "&lt;") are unescaped, tag names and attribute keys are
lower-cased, and attributes are collected into a []Attribute. For example:
for {
if z.Next() == html.ErrorToken {
// Returning io.EOF indicates success.
return z.Err()
}
emitToken(z.Token())
}
The low-level API performs fewer allocations and copies, but the contents of
the []byte values returned by Text, TagName and TagAttr may change on the next
call to Next. For example, to extract an HTML page's anchor text:
depth := 0
for {
tt := z.Next()
switch tt {
case html.ErrorToken:
return z.Err()
case html.TextToken:
if depth > 0 {
// emitBytes should copy the []byte it receives,
// if it doesn't process it immediately.
emitBytes(z.Text())
}
case html.StartTagToken, html.EndTagToken:
tn, _ := z.TagName()
if len(tn) == 1 && tn[0] == 'a' {
if tt == html.StartTagToken {
depth++
} else {
depth--
}
}
}
}
Parsing is done by calling Parse with an io.Reader, which returns the root of
the parse tree (the document element) as a *Node. It is the caller's
responsibility to ensure that the Reader provides UTF-8 encoded HTML. For
example, to process each anchor node in depth-first order:
doc, err := html.Parse(r)
if err != nil {
// ...
}
for n := range doc.Descendants() {
if n.Type == html.ElementNode && n.Data == "a" {
// Do something with n...
}
}
The relevant specifications include:
https://html.spec.whatwg.org/multipage/syntax.html and
https://html.spec.whatwg.org/multipage/syntax.html#tokenization
# Security Considerations
Care should be taken when parsing and interpreting HTML, whether full documents
or fragments, within the framework of the HTML specification, especially with
regard to untrusted inputs.
This package provides both a tokenizer and a parser, which implement the
tokenization, and tokenization and tree construction stages of the WHATWG HTML
parsing specification respectively. While the tokenizer parses and normalizes
individual HTML tokens, only the parser constructs the DOM tree from the
tokenized HTML, as described in the tree construction stage of the
specification, dynamically modifying or extending the document's DOM tree.
If your use case requires semantically well-formed HTML documents, as defined by
the WHATWG specification, the parser should be used rather than the tokenizer.
In security contexts, if trust decisions are being made using the tokenized or
parsed content, the input must be re-serialized (for instance by using Render or
Token.String) in order for those trust decisions to hold, as the process of
tokenization or parsing may alter the content.
*/
package html // import "golang.org/x/net/html"
// The tokenization algorithm implemented by this package is not a line-by-line
// transliteration of the relatively verbose state-machine in the WHATWG
// specification. A more direct approach is used instead, where the program
// counter implies the state, such as whether it is tokenizing a tag or a text
// node. Specification compliance is verified by checking expected and actual
// outputs over a test suite rather than aiming for algorithmic fidelity.
// TODO(nigeltao): Does a DOM API belong in this package or a separate one?
// TODO(nigeltao): How does parsing interact with a JavaScript engine?

// another <a> element: parsing "<a><a>" results in two sibling elements.
// Similarly, in a 'well-formed' parse tree, no <a> element is a child of a

// children; the <a> is reparented to the <table>'s parent. However, calling

// Package publicsuffix provides a public suffix list based on data from
// https://publicsuffix.org/
//
// A public suffix is one under which Internet users can directly register
// names. It is related to, but different from, a TLD (top level domain).
//
// "com" is a TLD (top level domain). Top level means it has no dots.
//
// "com" is also a public suffix. Amazon and Google have registered different
// siblings under that domain: "amazon.com" and "google.com".
//
// "au" is another TLD, again because it has no dots. But it's not "amazon.au".
// Instead, it's "amazon.com.au".
//
// "com.au" isn't an actual TLD, because it's not at the top level (it has
// dots). But it is an eTLD (effective TLD), because that's the branching point
// for domain name registrars.
//
// Another name for "an eTLD" is "a public suffix". Often, what's more of
// interest is the eTLD+1, or one more label than the public suffix. For
// example, browsers partition read/write access to HTTP cookies according to
// the eTLD+1. Web pages served from "amazon.com.au" can't read cookies from
// "google.com.au", but web pages served from "maps.google.com" can share
// cookies from "www.google.com", so you don't have to sign into Google Maps
// separately from signing into Google Web Search. Note that all four of those
// domains have 3 labels and 2 dots. The first two domains are each an eTLD+1,
// the last two are not (but share the same eTLD+1: "google.com").
//
// All of these domains have the same eTLD+1:
// - "www.books.amazon.co.uk"
// - "books.amazon.co.uk"
// - "amazon.co.uk"
//
// Specifically, the eTLD+1 is "amazon.co.uk", because the eTLD is "co.uk".
//
// There is no closed form algorithm to calculate the eTLD of a domain.
// Instead, the calculation is data driven. This package provides a
// pre-compiled snapshot of Mozilla's PSL (Public Suffix List) data at
