If you’ve ever built Mozilla from source or run the unit tests, you’ll know that doing so can generate a lot of console output. When errors happen, it can take a bit of scrolling to figure out exactly what failed, and where. I recently switched to pymake (because it’s sooo much faster), and it generates even more output.
Recently Shawn mentioned he had some magic pixie dust to colorize build output (which I didn’t know was possible on Windows), and I extended what he had to do a bit more. I’m finding it hugely useful, so figured I should share!
First, the pretty picture. This particular example is a bit gaudy, but shows a lot of what it does. The mostly useless nsinstall output (of which there’s a *lot*) is dark blue. Compiler warnings are yellow, errors are red.
Oh, and xpcshell tests benefit too!
To add this to your Windows MozillaBuild environment, just add this stuff to ~/.profile, and then open a new shell window.
There’s probably a lot more that could be done with this (and I’m sure it missed all kinds of interesting cases), but it’s a good, simple start!
