Chromium hacking

1. Set the args.gn as your gn build configuration
   • Probably best to run gn args out/Default and copy/paste what you want to use, then save.
2. source chromium.sh
3. git pull && depsbcr

That’s it. You can also run the various components of the bash script seperately and together.

• deps: run gclient sync to synchronize all the “submodule” dependencies
• hooks run gclient hooks, which is otherwise automaticaly run after deps.
• gom: initialize goma
• b: build/compile chrome
• cr: run the built chrome binary

I often do this sequence: git pull && deps && bcr followed by hacking followed by bcr, bcr, bcr.
