 '''colorize output from some commands
 
 This extension modifies the status and resolve commands to add color to their
 output to reflect file status, the qseries command to add color to reflect
 patch status (applied, unapplied, missing), and to diff-related
 commands to highlight additions, removals, diff headers, and trailing
 whitespace.
 
 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.
 
 Default effects may be overridden 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
 
   diff.diffline = bold
   diff.extended = cyan bold
   diff.file_a = red bold
   diff.file_b = green bold
   diff.hunk = magenta
   diff.deleted = red
   diff.inserted = green
   diff.changed = white
   diff.trailingwhitespace = bold red_background
 
   resolve.unresolved = red bold
   resolve.resolved = green bold
 
   bookmarks.current = green
