Subject: syntax highlighting for all formats supported by "highlight"
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/56522ebe1387721d10196e835346257e7494abad?ds=sidebyside;hp=56522ebe1387721d10196e835346257e7494abad

syntax highlighting for all formats supported by "highlight"

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.
