format: Ensure that formatting always reaches a fixedpoint in one run The .golden for this is ugly, but follows existing sources formatting e.g. in https://gn.googlesource.com/gn/+/master/tools/gn/format_test_data/062.golden#25 This at least causes formatting to reach a fixed point in one step, which is the more annoying bug. In practice, the user will probably fix the sorting to the actual desired formatting by manually sorting as was done in https://chromium-review.googlesource.com/c/chromium/src/+/1403177.

GN is a meta-build system that generates build files for Ninja. There is documentation in docs/ and a presentation on it.
You can download the latest version of GN binary for Linux, macOS and Windows.
Alternatively, you can build GN from source:
git clone https://gn.googlesource.com/gn cd gn python build/gen.py ninja -C out # To run tests: out/gn_unittests
On Windows, it is expected that cl.exe, link.exe, and lib.exe can be found in PATH, so you'll want to run from a Visual Studio command prompt, or similar.
On Linux and Mac, the default compiler is clang++, a recent version is expected to be found in PATH. This can be overridden by setting CC, CXX, and AR.
If you find a bug, you can see if it is known or report it in the bug database.
GN uses Gerrit for code review. The short version of how to patch is:
Register at https://gn-review.googlesource.com. ... edit code ... ninja -C out && out/gn_unittests
Then, to upload a change for review:
git commit git cl upload --gerrit
When revising a change, use:
git commit --amend git cl upload --gerrit
which will add the new changes to the existing code review, rather than creating a new one.
