WP Helpers

These are a few small utility functions that I use when working on WordPress.

Installation

These can be copied directly into your ~/.bashrc or ~/.zshrc file (whichever is applicable) or put them in a file that is added to your path. I use Oh My Zsh on my sytem, and have this file saved to ~/.oh-my-zsh/custom/plugins/wp-dev/wp-dev.plugin.zsh and have added wp-dev to the list of plugins in my .zshrc file.

What's included

gh-patch

Quickly apply a PR from https://github.com/WordPress/wordpress-develop as a patch to an SVN checkout of WordPress. This is a huge time saver when I'm committing changes to WordPress.

Goals

• Mimic the properties of WP_Post, and include additional metadata that's stored for images
  • _wp_attached_file
  • _wp_attachement_metadata
  • _wp_attachment_is_custom_background (maybe?)
• Include methods for retrieving data associated with an image, possibly replacing the wp_get_attachment_image_ family of functions.
• Save any reused data that would be used across functions so it's not calculated multiple times (e.g., wp_upload_dir(), see: #34359).
• Maintain backwards compatability with the media.php image functions.
