"""syntax highlighting for hgweb (requires Pygments)
|
|
|
|
|
|
It depends on the Pygments syntax highlighting library:
|
|
|
http://pygments.org/
|
|
|
|
|
|
There are the following configuration options::
|
|
|
|
|
|
[web]
|
|
|
pygments_style = <style> (default: colorful)
|
|
|
highlightfiles = <fileset> (default: size('<5M'))
|
|
|
highlightonlymatchfilename = <bool> (default False)
|
|
|
|
|
|
``highlightonlymatchfilename`` will only highlight files if their type could
|
|
|
be identified by their filename. When this is not enabled (the default),
|
|
|
Pygments will try very hard to identify the file type from content and any
|
|
|
match (even matches with a low confidence score) will be used.
|
|
