Edit constants and variables defined in wp-config.php

[danielbachhuber]

Editing a wp-config.php file programmatically is imprecise and error-prone, when it ideally would be as easy as running a WP-CLI command.

Borek Bernard has some suggestions for how to implement: wp-cli/wp-cli#2501

Started work on a command to do this. Very much a work in progress but initial functionality works well enough for some testing and input if anyones interested: https://github.com/emirpprime/config-update-command
There are various known problems [BUG] and missing features [TODO] commented in the code.

My starting point was to mimic config variables for familiarity / user expectations rather than introduce new behaviours.

Neat!

For programmatically editing a wp-config.php file, I was thinking about creating a new library to serve as an interface for editing the file. This would let us eventually write hundreds of tests for every possible combination of wp-config.php (and others could use it in other systems). Something you'd want to help hack on in a few weeks?

Yes happy to chip in - sounds like it might be a bit above my ability to do the heavy lifting but I'll do what I can!

This was implemented with wp-cli/config-command#44
