""" This is Mercurial extension for syntax highlighting in the file revision view of hgweb.

If this is changed the corresponding CSS file should be re-generated by running # pygmentize -f html -S <newstyle> -- Adam Hupp <adam@hupp.org> """ from mercurial import demandimport demandimport.ignore.extend(['pkgutil', 'pkg_resources', '__main__',]) from mercurial.hgweb.hgweb_mod import hgweb from mercurial import util from mercurial.templatefilters import filters from pygments import highlight from pygments.util import ClassNotFound from pygments.lexers import guess_lexer, guess_lexer_for_filename, TextLexer from pygments.formatters import HtmlFormatter SYNTAX_CSS = ('\n<link rel="stylesheet" href="#staticurl#highlight.css" ' 'type="text/css" />') def pygmentize(self, tmpl, fctx, field): # append a <link ...> to the syntax highlighting css old_header = ''.join(tmpl('header')) if SYNTAX_CSS not in old_header: new_header = old_header + SYNTAX_CSS tmpl.cache['header'] = new_header text = fctx.data() if util.binary(text): return style = self.config("web", "pygments_style", "colorful") # To get multi-line strings right, we can't format line-by-line try: lexer = guess_lexer_for_filename(fctx.path(), text, encoding=util._encoding) except ClassNotFound: try: lexer = guess_lexer(text, encoding=util._encoding) except ClassNotFound: lexer = TextLexer(encoding=util._encoding) formatter = HtmlFormatter(style=style, encoding=util._encoding) colorized = highlight(text, lexer, formatter) # strip wrapping div colorized = colorized[:colorized.find('\n</pre>')] colorized = colorized[colorized.find('<pre>')+5:] coloriter = iter(colorized.splitlines()) filters['colorize'] = lambda x: coloriter.next() oldl = tmpl.cache[field] newl = oldl.replace('line|escape', 'line|colorize') tmpl.cache[field] = newl def filerevision_highlight(self, tmpl, fctx): pygmentize(self, tmpl, fctx, 'fileline') return realrevision(self, tmpl, fctx) def fileannotate_highlight(self, tmpl, fctx): pygmentize(self, tmpl, fctx, 'annotateline') return realannotate(self, tmpl, fctx) # monkeypatch in the new version # should be safer than overriding the method in a derived class # and then patching the class realrevision = hgweb.filerevision hgweb.filerevision = filerevision_highlight realannotate = hgweb.fileannotate hgweb.fileannotate = fileannotate_highlight
