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.

cpplint.py

Until 2018, our cpplint.py was a copy of the upstream version at https://github.com/google/styleguide/tree/gh-pages/cpplint. Unfortunately, that repository is not maintained any more. If you want to update cpplint.py in depot_tools, just upload a patch to do so. We will figure out a long-term strategy via issue https://crbug.com/916550.

Note that the cpplint.py here is also used by the Tricium analyzer, so if the cpplint.py here changes, we should also update the copy used there.
