Subject: [sup-talk] [PATCH] Configurable coloring

From: [email-masked] (Dag Odenhall)

Hello good folks

This lil patch allows you to override these color symbols:

:status
:index_old
:index_new
:index_starred
:index_draft
:labellist_old
:labellist_new
:twiddle
:label
:message_patina
:alternate_patina
:missing_message
:attachment
:cryptosig_valid
:cryptosig_unknown
:cryptosig_invalid
:generic_notice_patina
:quote_patina
:sig_patina
:quote
:sig
:to_me
:starred
:starred_patina
:alternate_starred_patina
:snippet
:option
:tagged
:draft_notification
:completion_character
:horizontal_selector_selected
:horizontal_selector_unselected
:search_highlight

in your config.yaml. You can set :fg or :bg to any of:

default (transparent)
black
blue
cyan
green
magenta
red
white
yellow

You can also set :attrs to a list of any of:

horizontal
reverse
left
blink
low
dim
right
bold
top
protect
attributes
vertical
invis
normal
color
altcharset
standout
chartext
underline

This all goes under :colors, so an example would be:

:colors:
  :status:
    :fg: black
    :bg: red
    :attrs:
    - reverse
    - underline

This is all a quick hack that can probably be improved upon, but it
works fine.

Thanks Marc Hartstein for help with getting the transparency working.

Dag.
