[SVN] Revision 1864

[Allan Odgaard]

• added require_cmd which you can use to test for the existence of a (required) shell command, before actually using it

It outputs an error message containing the locations searched (as HTML) and if given a second argument, places that text in the output (wrapped in <p>…</p>). It exits on error.

E.g.: require_cmd ruby "You can set the <tt>TM_RUBY</tt> variable or add the location to your shell path."
or just: require_cmd pdflatex

For commands shipped with OS X, there's no need to use require_cmd.
