vim mapping for updating php whitepsace to WordPress standards

WordPress coding standards require spaces around parentheses, like this: if ( 'bar' == $foo ), but some people prefer to write it spaceless, like this: if('bar'==$foo). To update PHP whitespace to WP standards, I created this mapping:

map \ss :s/(\([^ )]\)/( \1/g<CR>:s/\([^ (]\))/\1 )/g

Explanation:

• :s/ - substitute the following
• ( - literal beginning parenthesis
• \( - beginning of group to be referenced later
• [^ )] - match anything except spaces and end parentheses, since we don't want to respace function calls like function().
• \) - end of group to be referenced later
• / - replace with the following
• ( - replace with an opening parenthesis and a space
• \1 - and add the first group referenced earlier
• /g - do this for every occurence on this line
• <CR> - press enter
• ... and do the same thing for closing parentheses.

To use it, put the line in your .vimrc, and type \ss for respacing a line of php.
