get-rss-from-forum - Generate an RSS page by parsing vBulletin forum display page


This document describes version 0.08 of get-rss-from-forum (from Perl distribution RSS-From-Forum-vBulletin), released on 2015-08-18.



 % get-rss-from-forum [options] <url>


Many vBulletin forums do not turn on RSS feeds. This function parses vBulletin forum display page and create a simple RSS page so you can subscribe to it using RSS.

Configuration options


{en_US Set path to configuration file}.

Can be specified multiple times.


{en_US Set configuration profile to use}.


{en_US Do not use any configuration file}.

{en_US Choose output format, e.g. json, text}.

{en_US Set output format to json}.


{en_US When outputing as JSON, strip result envelope}.

Default value:


{en_US By default, when outputing as JSON, the full enveloped result is returned, e.g.:


The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:


Other options

--help, -h, -?

{en_US Display help message and exit}.


{en_US Supply a custom LWP::UserAgent object} (JSON-encoded).

See --ua.


{en_US Supply a custom LWP::UserAgent object}.

{en_US If supplied, will be used instead of the default LWP::UserAgent object. }

{en_US Usually it's of the form: http://host/path/forumdisplay.php?f=XXX }

This script has shell tab completion capability with support for several shells.


To activate bash completion for this script, put:

 complete -C get-rss-from-forum get-rss-from-forum

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.


To activate tcsh completion for this script, put:

 complete get-rss-from-forum 'p/*/`get-rss-from-forum`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.



Specify additional command-line options


This script can read configuration file, which by default is searched at ~/.config/get-rss-from-forum.conf, ~/get-rss-from-forum.conf or /etc/get-rss-from-forum.conf (can be changed by specifying --config-path). All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

Configuration file is in the format of IOD, which is basically INI with some extra features.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

List of available configuration parameters:

 format (see --format)
 naked_res (see --naked-res)
 ua (see --ua)
 url (see --url)
