Mozilla developers often need to juggle multiple build configurations in their day to day work.
Strategies to manage this sometimes include complex shell scripting built into their mozconfig, or a
topsrcdir littered with mozconfig-* files and then calls to the build system like
MOZCONFIG=mozconfig-debug ./mach build. But there’s another method (which is basically just a
variant on the latter), that might help make managing mozconfigs a teensy bit easier:
mozconfigwrapper.
In the interest of not documenting things in blog posts (and because I’m short on time this morning), I invite you to read the README file of the repo for installation and usage instructions. Please file issues and don’t hesitate to reach out if the README is not clear or you have any problems.
