r8932 | """syntax highlighting for hgweb (requires Pygments) | ||
|
r6938 | |||
|
r9262 | It depends on the Pygments syntax highlighting library: | ||
http://pygments.org/ | ||||
|
r6938 | |||
|
r26680 | There are the following configuration options:: | ||
|
r6938 | |||
|
r9210 | [web] | ||
r26249 | pygments_style = <style> (default: colorful) | |||
highlightfiles = <fileset> (default: size('<5M')) | ||||
|
r26680 | 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. | ||||
