Git pre-commit hook gist

Question

I found this snippet of code https://gist.github.com/wrboyce/786460

#!/usr/bin/zsh COMPRESSOR=$(whence -p yui-compressor) [ -z $COMPRESSOR ] && exit 0; function _compress { local fname=$1:t local dest_path=$1:h local min_fname="$dest_path/${fname:r}.min.${fname:e}" $COMPRESSOR $1 > $min_fname git add $min_fname } for file in $(find . -regextype posix-extended -iregex '.+\.(css|js)$' -and -not -iregex '.+\.min\.(css|js)$'); _compress $file

On my osx machine it says:

.git/hooks/pre-commit: line 2: whence: command not found

I believe this is for linux only? Could anyone help to do this on a mac? I want to minify my css and javascript before it is sent to the remote production server.

Yes it's for Linux only:

The whence command is a Korn Shell feature that tells how a name would be interpreted by the shell: it detects commands and aliases, and searches your path.

Try this:

#!/usr/bin/zsh COMPRESSOR=$(which yui-compressor) [ -z $COMPRESSOR ] && exit 0; function _compress { local fname=$1:t local dest_path=$1:h local min_fname="$dest_path/${fname:r}.min.${fname:e}" $COMPRESSOR $1 > $min_fname git add $min_fname } for file in $(find . -regextype posix-extended -iregex '.+\.(css|js)$' -and -not -iregex '.+\.min\.(css|js)$'); _compress $file

Strange, whence is also a zsh builtin. I actually wrote the original gist on my OSX machine.
