'''colorize output from some commands
|
|
|
|
|
|
The color extension colorizes output from several Mercurial commands.
|
|
|
For example, the diff command shows additions in green and deletions
|
|
|
in red, while the status command shows modified files in magenta. Many
|
|
|
other commands have analogous colors. It is possible to customize
|
|
|
these colors.
|
|
|
|
|
|
Effects
|
|
|
-------
|
|
|
|
|
|
Other effects in addition to color, like bold and underlined text, are
|
|
|
also available. By default, the terminfo database is used to find the
|
|
|
terminal codes used to change color and effect. If terminfo is not
|
|
|
available, then effects are rendered with the ECMA-48 SGR control
|
|
|
function (aka ANSI escape codes).
|
|
|
|
|
|
The available effects in terminfo mode are 'blink', 'bold', 'dim',
|
|
|
'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
|
|
|
ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and
|
|
|
'underline'. How each is rendered depends on the terminal emulator.
|
|
|
Some may not be available for a given terminal type, and will be
|
|
|
silently ignored.
|
|
|
|
|
|
Labels
|
|
|
------
|
|
|
|
|
|
Text receives color effects depending on the labels that it has. Many
|
|
|
default Mercurial commands emit labelled text. You can also define
|
|
|
your own labels in templates using the label function, see :hg:`help
|
|
|
templates`. A single portion of text may have more than one label. In
|
|
|
that case, effects given to the last label will override any other
|
|
|
effects. This includes the special "none" effect, which nullifies
|
|
|
other effects.
|
|
|
|
|
|
Labels are normally invisible. In order to see these labels and their
|
|
|
position in the text, use the global --color=debug option. The same
|
|
|
anchor text may be associated to multiple labels, e.g.
|
|
|
|
|
|
[log.changeset changeset.secret|changeset: 22611:6f0a53c8f587]
|
|
|
|
|
|
The following are the default effects for some default labels. Default
|
|
|
effects may be overridden from your configuration file::
|
|
|
|
|
|
[color]
|
|
|
status.modified = blue bold underline red_background
|

status.added = green bold

|

|
|

Custom colors
|
|
|
-------------
|
|
|
|
|
|
Because there are only eight standard colors, this module allows you
|
|
|
to define color names for other color slots which might be available
|
|
|
for your terminal type, assuming terminfo mode. For instance::
|
|
|
|
|
|
color.brightblue = 12
|
|
|
color.pink = 207
|
|
|
color.orange = 202
|
|
|
|
|
|
to set 'brightblue' to color slot 12 (useful for 16 color terminals
|
|
|
that have brighter colors defined in the upper eight) and, 'pink' and
|
|
|
'orange' to colors in 256-color xterm's default color cube. These
|
|
|
defined colors may then be used as any of the pre-defined eight,
|
|
|
including appending '_background' to set the background to that color.
|
|
|
|
|
|
Modes
|
|
|
-----
|
|
|
|
|
|
By default, the color extension will use ANSI mode (or win32 mode on
|
|
|
Windows) if it detects a terminal. To override auto mode (to enable
|
|
|
terminfo mode, for example), set the following configuration option::
|
|
|
|
|
|
[color]
|
|
|
mode = terminfo
|
|
|
|
|
|
Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will
|
|
|
disable color.
|
|
|
|
|
|
Note that on some systems, terminfo mode may cause problems when using
|
|
|
color with the pager extension and less -R. less with the -R option
|
|
|
will only display ECMA-48 color codes, and terminfo mode may sometimes
|
|
|
emit codes that less doesn't understand. You can work around this by
|
|
|
either using ansi mode (or auto mode), or by using less -r (which will
|
|
|
pass through all terminal control codes, not just color control
|
|
|
codes).
|
|
|
|
|
|
On some systems (such as MSYS in Windows), the terminal may support
|
|
|
a different color mode than the pager (activated via the "pager"
|
|
|
extension). It is possible to define separate modes depending on whether
|
|
|
the pager is active::
|
|
|
|
|
|
[color]
|
|
|
mode = auto
|
|
|
pagermode = ansi
|
|
|
|
|
|
If ``pagermode`` is not defined, the ``mode`` will be used.
