2 # This script can be used to implement syntax highlighting in the cgit
3 # tree-view by refering to this file with the source-filter or repo.source-
4 # filter options in cgitrc.
6 # This script requires a shell supporting the ${var##pattern} syntax.
7 # It is supported by at least dash and bash, however busybox environments
8 # might have to use an external call to sed instead.
10 # Note: the highlight command (http://www.andre-simon.de/) uses css for syntax
11 # highlighting, so you'll probably want something like the following included
12 # in your css file (generated by highlight 2.4.8 and adapted for cgit):
14 # table.blob .num { color:#2928ff; }
15 # table.blob .esc { color:#ff00ff; }
16 # table.blob .str { color:#ff0000; }
17 # table.blob .dstr { color:#818100; }
18 # table.blob .slc { color:#838183; font-style:italic; }
19 # table.blob .com { color:#838183; font-style:italic; }
20 # table.blob .dir { color:#008200; }
21 # table.blob .sym { color:#000000; }
22 # table.blob .kwa { color:#000000; font-weight:bold; }
23 # table.blob .kwb { color:#830000; }
24 # table.blob .kwc { color:#000000; font-weight:bold; }
25 # table.blob .kwd { color:#010181; }
27 # store filename and extension in local vars
29 EXTENSION="${BASENAME##*.}"
31 # map Makefile and Makefile.* to .mk
32 [ "${BASENAME%%.*}" == "Makefile" ] && EXTENSION=mk
34 # highlight versions 2 and 3 have different commandline options. Specifically,
35 # the -X option that is used for version 2 is replaced by the -O xhtml option
38 # Version 2 can be found (for example) on EPEL 5, while version 3 can be
39 # found (for example) on EPEL 6.
41 # This is for version 2
42 exec highlight --force -f -I -X -S $EXTENSION 2>/dev/null
44 # This is for version 3
46 # On CentOS 6.2 (using highlight from EPEL), when highlight doesn't know about
47 # an EXTENSION, it outputs a lua error and _no_ text, even when the --force
50 # Also see the bug reports at:
51 # http://sourceforge.net/tracker/?func=detail&aid=3490017&group_id=215618&atid=1034391
52 # https://bugzilla.redhat.com/show_bug.cgi?id=795567
54 # This workaround can be removed when the bug is fixed upstream and the new
55 # version is packaged in most distributions.
57 # The workaround is to set the extension to 'txt' (plain text) when highlight
58 # exits with an error (doesn't know the format).
60 #echo "test" | highlight -f -I -O xhtml -S $EXTENSION &>/dev/null
61 #[ ${?} -ne 0 ] && EXTENSION="txt"
62 #exec highlight --force -f -I -O xhtml -S $EXTENSION 2>/dev/null
