'''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).
Default effects may be overridden from your configuration 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
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
The color extension will try to detect whether to use ANSI codes or
Win32 console APIs, unless it is made explicit::
[color]
mode = ansi
Any value other than 'ansi', 'win32', or 'auto' will disable color.
