## Paste. ##
This is pastebin replacement. It does not use ads, it is opensource it is relatively small.
And it has minimal pastebin API stub, at least pastebinit can paste to it with minimal config changes.
Besides pastebinit there are 2 cli clients available on main page of this app.
### How do I get set up? ###
This paste utilizes PDO SQLite driver, well, at least for now :) and mbstrings.
Tested php versions are 5.6.30 and 7.0.12. Paste uses **paste/paste.sqlite** file as db.
Tested on apache/fcgid (windows) for dev and nginx/php-fpm for prod.
Default installation assumes that paste runs as / app on site, but you can change it (BASEURL) in index.php.
Nginx config snippet:
```
# limit paste size to ~ 200k
client_max_body_size 256k;
location /raw {
rewrite "^\/raw\/([a-z|A-Z]*)$" /index.php?$1;
}
rewrite "^/([a-z|A-Z]*)$" /index.php?$1;
location / {
root /var/www/htdocs/empty;
index index.php;
location ~ \.php$ {
if ($request_method !~ ^(GET|HEAD|POST)$ ) {
return 499;
}
root /var/www/htdocs;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
#NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_pass php;
}
}
```
Database initialises automatically :)
### Contribution guidelines ###
Clean code, preferably with comments for some quirky places.
### PasteBinIt configuration ###
default pastebin site, __~/.pastebinit.xml__:
```
<pastebinit>
<pastebin>http://your.site</pastebin>
<author>Stephane Graber</author>
<jabberid>stgraber@stgraber.org</jabberid>
<format>text</format>
</pastebinit>
```
and how to work with it __~/.pastebinit.d/your.site.conf__:
```
[pastebin]
basename = your.site
regexp = http://((([a-zA-Z0-9\-_\.]*)(your\.site)))
[format]
content = api_paste_code
user = api_paste_name
subdomain = api_paste_subdomain

expiry = api_paste_expire_date

DESCRIPTION
Upload data and fetch URL from the pastebin <?php print SITE_ADDRESS; ?>
USAGE
$0 filename.txt
$0 text string
$0 < filename.txt
piped_data | $0
NOTES
--------------------------------------------------------------------------
* INPUT METHODS *
$0 can accept piped data, STDIN redirection [<filename.txt], text strings following the command as arguments, or filenames as arguments. Only one of these methods can be used at a time, so please see the note on precedence. Also, note that using a pipe or STDIN redirection will treat tabs as spaces, or disregard them entirely (if they appear at the beginning of a line). So I suggest using a filename as an argument if tabs are important either to the function or readability of the code.
* PRECEDENCE *
STDIN redirection has precedence, then piped input, then a filename as an argument, and finally text strings as an arguments.
EXAMPLE:
echo piped | "$0" arguments.txt < stdin_redirection.txt
In this example, the contents of file_as_stdin_redirection.txt would be uploaded. Both the piped_text and the file_as_argument.txt are ignored. If there is piped input and arguments, the arguments will be ignored, and the piped input uploaded.
* FILENAMES *
If a filename is misspelled or doesn\'t have the necessary path description, it will NOT generate an error, but will instead treat it as a text string and upload it.
