#!/bin/sh
# This script can be used to implement syntax highlighting in the cgit
# tree-view by refering to this file with the source-filter or repo.source-
# filter options in cgitrc.
#
+# This script requires a shell supporting the ${var##pattern} syntax.
+# It is supported by at least dash and bash, however busybox environments
+# might have to use an external call to sed instead.
+#
# Note: the highlight command (http://www.andre-simon.de/) uses css for syntax
# highlighting, so you'll probably want something like the following included
# in your css file (generated by highlight 2.4.8 and adapted for cgit):
#
# table.blob .num { color:#2928ff; }
# table.blob .esc { color:#ff00ff; }
# table.blob .str { color:#ff0000; }
# table.blob .dstr { color:#818100; }
# table.blob .slc { color:#838183; font-style:italic; }
# table.blob .com { color:#838183; font-style:italic; }
# table.blob .dir { color:#008200; }
# table.blob .sym { color:#000000; }
# table.blob .kwa { color:#000000; font-weight:bold; }
# table.blob .kwb { color:#830000; }
# table.blob .kwc { color:#000000; font-weight:bold; }
# table.blob .kwd { color:#010181; }
