[args] Fix gn args unstable output Before this patch, the 'gn args --list --json' is non-deterministic due to the fact that ArgumentsPerToolchain is unordered. This patch fix this issue. Bug: crbug.com/gn/83 Change-Id: Iacf469f99708c43d32b952da2727da2b279afd99 Reviewed-on: https://gn-review.googlesource.com/c/gn/+/5060 Reviewed-by: Brett Wilson <brettw@google.com> Commit-Queue: Haowei Wu <haowei@google.com>
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.
