8 | 8 | '''colorize output from some commands |
|
9 | 9 | |
|
10 | 10 | The color extension colorizes output from several Mercurial commands. |
|
11 | 11 | For example, the diff command shows additions in green and deletions |
|
12 | 12 | in red, while the status command shows modified files in magenta. Many |
|
13 | 13 | other commands have analogous colors. It is possible to customize |
|
14 | 14 | these colors. |
|
15 | 15 | |
|
16 | 16 | Effects |
|
17 | 17 | ------- |
|
18 | 18 | |
|
19 | 19 | Other effects in addition to color, like bold and underlined text, are |
|
20 | 20 | also available. By default, the terminfo database is used to find the |
|
21 | 21 | terminal codes used to change color and effect. If terminfo is not |
|
22 | 22 | available, then effects are rendered with the ECMA-48 SGR control |
|
23 | 23 | function (aka ANSI escape codes). |
|
24 | 24 | |
|
25 | 25 | The available effects in terminfo mode are 'blink', 'bold', 'dim', |
|
26 | 26 | 'inverse', 'invisible', 'italic', 'standout', and 'underline'; in |
|
27 | 27 | ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and |
|
28 | 28 | 'underline'. How each is rendered depends on the terminal emulator. |
|
29 | 29 | Some may not be available for a given terminal type, and will be |
|
30 | 30 | silently ignored. |
|
31 | 31 | |
|
32 | 32 | Labels |
|
33 | 33 | ------ |
|
34 | 34 | |
|
35 | 35 | Text receives color effects depending on the labels that it has. Many |
|
36 | 36 | default Mercurial commands emit labelled text. You can also define |
|
37 | 37 | your own labels in templates using the label function, see :hg:`help |
|
38 | 38 | templates`. A single portion of text may have more than one label. In |
|
39 | 39 | that case, effects given to the last label will override any other |
|
40 | 40 | effects. This includes the special "none" effect, which nullifies |
|
41 | 41 | other effects. |
|
42 | 42 | |
|
43 | 43 | Labels are normally invisible. In order to see these labels and their |
|
44 | 44 | position in the text, use the global --color=debug option. The same |
|
45 | 45 | anchor text may be associated to multiple labels, e.g. |
|
46 | 46 | |
|
47 | 47 | [log.changeset changeset.secret|changeset: 22611:6f0a53c8f587] |
|
48 | 48 | |
|
49 | 49 | The following are the default effects for some default labels. Default |
|
50 | 50 | effects may be overridden from your configuration file:: |
|
51 | 51 | |
|
52 | 52 | [color] |
|
53 | 53 | status.modified = blue bold underline red_background |
|
54 | 54 | status.added = green bold |

55 | 55 | status.removed = red bold blue_background |
|
56 | 56 | status.deleted = cyan bold underline |
|
57 | 57 | status.unknown = magenta bold underline |
|
58 | 58 | status.ignored = black bold |
|
59 | 59 | |
|
60 | 60 | # 'none' turns off all effects |
|
61 | 61 | status.clean = none |
|
62 | 62 | status.copied = none |
|
63 | 63 | |

64 | 64 | qseries.applied = blue bold underline |
|
65 | 65 | qseries.unapplied = black bold |

66 | 66 | qseries.missing = red bold |

71 | 71 | diff.file_b = green bold |
|
72 | 72 | diff.hunk = magenta |
|
73 | 73 | diff.deleted = red |
|
74 | 74 | diff.inserted = green |
|
75 | 75 | diff.changed = white |
|
76 | 76 | diff.tab = |
|
77 | 77 | diff.trailingwhitespace = bold red_background |
|
78 | 78 | |
|
79 | 79 | # Blank so it inherits the style of the surrounding label |
|
80 | 80 | changeset.public = |
|
81 | 81 | changeset.draft = |
|
82 | 82 | changeset.secret = |
|
83 | 83 | |
|
84 | 84 | resolve.unresolved = red bold |
|
85 | 85 | resolve.resolved = green bold |
|
86 | 86 | |
|
87 | 87 | bookmarks.active = green |
|
88 | 88 | |
|
89 | 89 | branches.active = none |
|
90 | 90 | branches.closed = black bold |
|
91 | 91 | branches.current = green |

|
98 | 98 | rebase.remaining = red bold |
|
99 | 99 | |
|
100 | 100 | shelve.age = cyan |
|
101 | 101 | shelve.newest = green bold |
|
102 | 102 | shelve.name = blue bold |

|
104 | 104 | histedit.remaining = red bold |

105 | 105 | |
|
106 | 106 | Custom colors |
|
107 | 107 | ------------- |
|
108 | 108 | |
|
109 | 109 | Because there are only eight standard colors, this module allows you |
|
110 | 110 | to define color names for other color slots which might be available |
|
111 | 111 | for your terminal type, assuming terminfo mode. For instance:: |
|
112 | 112 | |
|
113 | 113 | color.brightblue = 12 |
|
114 | 114 | color.pink = 207 |
|
115 | 115 | color.orange = 202 |
|
116 | 116 | |
|
117 | 117 | to set 'brightblue' to color slot 12 (useful for 16 color terminals |
|
118 | 118 | that have brighter colors defined in the upper eight) and, 'pink' and |
|
119 | 119 | 'orange' to colors in 256-color xterm's default color cube. These |
|
120 | 120 | defined colors may then be used as any of the pre-defined eight, |
|
121 | 121 | including appending '_background' to set the background to that color. |
|
122 | 122 | |
|
123 | 123 | Modes |
|
124 | 124 | ----- |
|
125 | 125 | |
|
126 | 126 | By default, the color extension will use ANSI mode (or win32 mode on |
|
127 | 127 | Windows) if it detects a terminal. To override auto mode (to enable |
|
128 | 128 | terminfo mode, for example), set the following configuration option:: |
|
129 | 129 | |
|
130 | 130 | [color] |
|
131 | 131 | mode = terminfo |
|
132 | 132 | |
|
133 | 133 | Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will |
|
134 | 134 | disable color. |
|
135 | 135 | |
|
136 | 136 | Note that on some systems, terminfo mode may cause problems when using |
|
137 | 137 | color with the pager extension and less -R. less with the -R option |
|
138 | 138 | will only display ECMA-48 color codes, and terminfo mode may sometimes |
|
139 | 139 | emit codes that less doesn't understand. You can work around this by |
|
140 | 140 | either using ansi mode (or auto mode), or by using less -r (which will |
|
141 | 141 | pass through all terminal control codes, not just color control |
|
142 | 142 | codes). |
|
143 | 143 | |
|
144 | 144 | On some systems (such as MSYS in Windows), the terminal may support |
|
145 | 145 | a different color mode than the pager (activated via the "pager" |
|
146 | 146 | extension). It is possible to define separate modes depending on whether |
|
147 | 147 | the pager is active:: |
|
148 | 148 | |
|
149 | 149 | [color] |
|
150 | 150 | mode = auto |
|
151 | 151 | pagermode = ansi |
|
152 | 152 | |
|
153 | 153 | If ``pagermode`` is not defined, the ``mode`` will be used. |
