# Usage
# =====
# Once loaded, this script will record the nicks of each new
# message. If the user leaves the room, the messages will be rewritten
# with the nick in another colour/style.
#
# Depending on your theme, tweaking the forms settings may be
# necessary. With the default irssi theme, this script should just
# work.
# Options
# =======
# /set dim_nicks_color
# * the colour code to use for dimming the nick, or a string of format
# codes with the special token $* in place of the nick (e.g. %I$*%I
# for italic)
#
# /set dim_nicks_history_lines
# * only this many lines of messages are remembered/rewritten (per
# window)
#
# /set dim_nicks_ignore_hilights
# * ignore lines with hilight when dimming
#
# /set dim_nicks_forms_skip
# /set dim_nicks_forms_search_max
# * these two settings limit the range where to search for the
# nick.
# It sets how many forms (blocks of irssi format codes or
# non-letters) to skip at the beginning of line before starting to
# search for the nick, and from then on how many forms to search
# before stopping.
# You should set this to the appropriate values to avoid (a) dimming
# your timestamp (b) dimming message content instead of the nick.
# To check your settings, you can use the command
# /script exec Irssi::Script::dim_nicks::debug_forms
