|
Mercurial colorizes output from several 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.
|
|
|
|
|
|
To enable color (default) whenever possible use::
|
|
|
|
|
|
[ui]
|
|
|
color = yes
|
|
|
|
|
|
To disable color use::
|
|
|
|
|
|
[ui]
|
|
|
color = no
|
|
|
|
|
|
See :hg:`help config.ui.color` for details.
|
|
|
|
|
|
.. container:: windows
|
|
|
|
|
|
The default pager on Windows does not support color, so enabling the pager
|
|
|
will effectively disable color. See :hg:`help config.ui.paginate` to disable
|
|
|
the pager. Alternately, MSYS and Cygwin shells provide `less` as a pager,
|
|
|
which can be configured to support ANSI color mode. Windows 10 natively
|
|
|
supports ANSI color mode.
|
|
|
|
|
|
Mode
|
|
|
====
|
|
|
|
|
|
Mercurial can use various systems to display color. The supported modes are
|
|
|
``ansi``, ``win32``, and ``terminfo``. See :hg:`help config.color` for details
|
|
|
about how to control the mode.
|
|
|
|
|
|
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.
|
|
|
|
|
|
If the terminfo entry for your terminal is missing codes for an effect
|
|
|
or has the wrong codes, you can add or override those codes in your
|
|
|
configuration::
|
|
|
|
|
|
[color]
|
|
|
terminfo.dim = \E[2m
|
|
|
|
|
|
where '\E' is substituted with an escape character.
|
|
|
|
|
|
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
|

|

Custom colors
|
|
|
=============
|
|
|
|
|
|
Because there are only eight standard colors, Mercurial 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.
