Fix gn meta to handle non-string metadata Before this patch, 'gn meta' will fail if the meta data is not a string. This patch fixes this problem. This patch also fixes the problem that rebase is invoked even if '-rebase-files ' flag is not used. Bug: crbug.com/gn/67 Change-Id: I0890b5dec5e7331c69c055fc8f13fe81dedbce83 Reviewed-on: https://gn-review.googlesource.com/c/gn/+/4660 Reviewed-by: Julie Hockett <juliehockett@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.
