bctrainers/urlbuffer

A znc module that caches images from links posted on irc channels.

#Urlbuffer

This znc module listens to traffic on irc channels and scans for image links (or just links). If an image link is detected it downloads the image to a given directory and reuploads it to imgur.com. Also if bufferalllinks is enabled then it will append each non image link found to a links.txt file in the current day directory.

##Dependencies

The module needs wget, sed, curl, a unix enviroment and a directory with write access for the znc user, to work.

##Usage

Compile it with znc-buildmod urlbuffer.cpp and move the .so file to the appropriate znc directory (usually /usr/lib/znc/ or ~/.znc/modules).

The module takes no arguments. Read loading modules to learn more about loading modules.

##Commands

!showlinks <#number> in your irc client displays the <#number> last links buffered. If you don't give a <#number the default (<#buffersize>) will be used. Each link is sent with a 2 second delay to avoid flooding users.
