A HexChat addon that uses "@" for nick completion on Gitter's IRC gateway
By default HexChat uses a suffix for nick completion when pressing <Tab>, if
the nick is typed at the beginning of a message (it usually is a colon, set in
the preferences).
If you use Gitter from HexChat this doesn't go well with "mentions", that need
@username to work. This addon changes this behavior only for channels opened
using the Gitter irc server, placing the @ at the beginning of the nick and then
cycles the matching nicks as usual.
Download the file gitter-nick-completion.py and put it in the HexChat addons
directory (usually ~/.config/hexchat/addons on Linux and
%APPDATA%\HexChat\addons on Windows), or load it from the "Plugins and
scripts" dialog you can access from the "Settings" menu.
