Paweł Hajdan, Jr e79ddeaabf gclient flatten: preserve variable placeholders
One of the main use cases is making it clear which revision hashes
need to be changed together. The way it's usually done is one variable
referenced several times. With this CL, we preserve the references
from original DEPS, as opposed to evaluating them and losing some info.

This CL actually makes Var() emit a variable placeholder
instead of its value, and adds support for these placeholders
to gclient.

One of possible next steps might be to deprecate Var().

README.md

depot_tools

Tools for working with Chromium development. It requires python 2.7.

Tools

The most important tools are:

  • fetch: A gclient wrapper to checkout a project. Use fetch --help for more details.
  • gclient: A meta-checkout tool. Think repo or git submodules, except that it support OS-specific rules, e.g. do not checkout Windows only dependencies when checking out for Android. Use gclient help for more details and README.gclient.md.
  • git cl: A code review tool to interact with Rietveld or Gerrit. Use git cl help for more details and README.git-cl.md.
  • roll-dep: A gclient dependency management tool to submit a dep roll, updating a dependency to a newer revision.

There are a lot of git utilities included.

Updating

depot_tools updates itself automatically when running gclient tool. To disable auto update, set the environment variable DEPOT_TOOLS_UPDATE=0.

To update package manually, run update_depot_tools.bat on Windows, or ./update_depot_tools on Linux or Mac.

On Windows only, running gclient will install git and python.
