* syntax highlighting for all formats supported by "highlight"Georg Lukas2009-11-191-17/+12
| | | | | | | | | | | | | | | | | | The highlight tool can be given any of the supported file extensions as its -S parameter. This patch replaces the case-switch by extracting the extension from the supplied file name and passing it to highlight. However, this requires a shell supporting the ${var##pattern} syntax, like dash or bash. Unknown extensions cause a fall-back to plain text using the --force switch. Error messages are redirected to /dev/null. A special case maps Makefile and Makefile.* to the "mk" extension. The total overhead is reduced by calling "exec highlight". No forks are needed during script execution. Signed-off-by: Georg Lukas <georg@op-co.de>
