# This is a simple weechat script that displays the number of unread emails in
# the status bar. The unread mail count is fetched from one of more (local)
# directories in Maildir format. If there is no unread mail, nothing will be
# displayed.
#
# Written by Yoran Heling <projects@yorhel.nl>
#
#
# Usage:
# - Copy/save this script to $HOME/.weechat/perl/maildir.pl
# - In weechat, type:
#     /perl load perl/maildir.pl
# - Add the string "[maildir]" somewhere to /set weechat.bar.status.items
# - Set the directory to watch:
#     /set plugins.var.perl.maildir.dir /home/yorhel/.mail/inbox
#   You can specify multiple directories by separating them with a comma.
# - (Optionally) set the update interval:
#     /set plugins.var.perl.maildir.interval 30
#     /perl reload maildir
#   The default of 10 seconds will usually work fine.
#
#
# 2012-11-26 - 1.1
#   - Use empty string to clear bar item.
#
# 2012-10-07 - 1.0
#   - Initial version
