2 | 2 | This is Mercurial extension for syntax highlighting in the file |
|
3 | 3 | revision view of hgweb. |
|
4 | 4 | |
|
5 | 5 | It depends on the pygments syntax highlighting library: |
|
6 | 6 | http://pygments.org/ |
|
7 | 7 | |
|
8 | 8 | To enable the extension add this to hgrc: |
|
9 | 9 | |
|
10 | 10 | [extensions] |
|
11 | 11 | hgext.highlight = |
|
12 | 12 | |
|
13 | 13 | There is a single configuration option: |
|
14 | 14 | |
|
15 | 15 | [web] |
|
16 | 16 | pygments_style = <style> |
|
17 | 17 | |
|
18 | 18 | The default is 'colorful'. If this is changed the corresponding CSS |
|
19 | 19 | file should be re-generated by running |
|
20 | 20 | |
|
21 | 21 | # pygmentize -f html -S <newstyle> |
