This is Mercurial extension for syntax highlighting in the file
|
|
|
revision view of hgweb.
|
|
|
|
|
|
It depends on the pygments syntax highlighting library:
|
|
|
http://pygments.org/
|
|
|
|
|
|
To enable the extension add this to hgrc:
|
|
|
|
|
|
[extensions]
|
|
|
hgext.highlight =
|
|
|
|
|
|
There is a single configuration option:
|
|
|
|
|
|
[web]
|
|
|
pygments_style = <style>
|
|
|
|
|
|
The default is 'colorful'. If this is changed the corresponding CSS
|
|
|
file should be re-generated by running
|
|
|
|
|
|
# pygmentize -f html -S <newstyle>
