11 """syntax highlighting for hgweb (requires Pygments)
13 It depends on the Pygments syntax highlighting library:
16 There is a single configuration option::
19 pygments_style = <style>
21 The default is 'colorful'.
25 from mercurial.hgweb import webcommands, webutil, common
26 from mercurial import extensions, encoding
28 def filerevision_highlight(orig, web, tmpl, fctx):
29 mt = ''.join(tmpl('mimetype', encoding=encoding.encoding))
30 # only pygmentize for mimetype containing 'html' so we both match
31 # 'text/html' and possibly 'application/xhtml+xml' in the future
32 # so that we don't have to touch the extension when the mimetype
33 # for a template changes; also hgweb optimizes the case that a
34 # raw file is sent using rawfile() and doesn't call us, so we
35 # can't clash with the file's content-type here in case we
36 # pygmentize a html file
38 style = web.config('web', 'pygments_style', 'colorful')
39 highlight.pygmentize('fileline', fctx, style, tmpl)
40 return orig(web, tmpl, fctx)
42 def annotate_highlight(orig, web, req, tmpl):
43 mt = ''.join(tmpl('mimetype', encoding=encoding.encoding))
45 fctx = webutil.filectx(web.repo, req)
46 style = web.config('web', 'pygments_style', 'colorful')
47 highlight.pygmentize('annotateline', fctx, style, tmpl)
48 return orig(web, req, tmpl)
50 def generate_css(web, req, tmpl):
51 pg_style = web.config('web', 'pygments_style', 'colorful')
52 fmter = highlight.HtmlFormatter(style = pg_style)
53 req.respond(common.HTTP_OK, 'text/css')
54 return ['/* pygments_style = %s */\n\n' % pg_style, fmter.get_style_defs('')]
56 # monkeypatch in the new version
57 extensions.wrapfunction(webcommands, '_filerevision', filerevision_highlight)
58 extensions.wrapfunction(webcommands, 'annotate', annotate_highlight)
59 webcommands.highlightcss = generate_css
60 webcommands.__all__.append('highlightcss')
