So when I got introduced too Ruby (RoR) and its possibility to generate prefab code from the command-line with a single command I wanted this for WordPress. And especially in combination with wp-cli. Sebastiaan had already jump started a part of the wp-cli scaffold command as a plugin.
We started working on it together to get it into the WP-CLI core. A while later the pull request was merged, tweaked by scribu and now you can enjoy a brand new command.
Enjoy these commands, we hope it will speed-up and ease your development with WordPress!
