This is the entire "Function Reference" section of the WordPress Codex, as retrieved sometime around mid-May 2013, converted to man page format.

I'm just trying this out for usefulness, if I or anyone else finds that it's helpful, I'll probably add some more utility functions for automatically updating, and an install script/package.

For now, you can just clone the repo or download it, and manually alias a function to look up these man pages.

For example, if you clone this repo to ~/bin/wpman, try adding this line to your ~/.bash_aliases:

function wpman () { man -M ~/bin/wpman $1; }

Then the command wpman will be available from your prompt, like so:

$ wpman wp_dropdown_categories

If you use pman, you could also just copy all of these files into the directory pman keeps its documentation. On my machine that was /usr/share/php/doc/pman/. This is obviously a stupid approach, but if you're like me and just want to be able to look up all your function definitions in one place, it works.

How it was made:

• I used a scraper hosted on scraperwiki to pull down a list of pages on the Codex - source here,
• retrieved all pages with "Function Reference" in the title using wget,
• used pandoc to convert them all to markdown,
• did some minor quick-and-dirty processing of the markdown files with sed and vim to get it closer to the format of a man page, and
• finally converted the markdown files into roff format using md2man (for some reason pandoc's output was always corrupted.)
