'''add color output to the status and qseries commands
This extension modifies the status command to add color to its output to
reflect file status, and the qseries command to add color to reflect patch
status (applied, unapplied, missing). Other effects in addition to color,
like bold and underlined text, are also available. Effects are rendered
with the ECMA-48 SGR control function (aka ANSI escape codes). This module
also provides the render_text function, which can be used to add effects to
any text.
To enable this extension, add this to your .hgrc file:
[extensions]
color =
Default effects my be overriden from the .hgrc file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
