Chromium and Chromium OS use a package of scripts called
depot_tools to manage checkouts and code reviews. This package
also includes the gclient utility.
gclient is a Python script to manage a workspace of modular dependencies that
are each checked out independently from different subversion or git
repositories. Features include:
- Dependencies can be specified on a per-OS basis.
- Dependencies can be specified relative to their parent dependency.
- Variables can be used to abstract concepts.
- Hooks can be specified to be run after a checkout.
- .gclient and DEPS are Python scripts. You can hack in easily or add
additional configuration data.
.gclient file: It's the primary file. It is, in fact, a Python script. It
specifies the following variables:
- solutions: an array of dictionaries specifying the projects that will be
fetched.
- hooks: additional hooks to be run when this meta checkout is synced.
- target_os: an optional array of (target) operating systems to fetch
OS-specific dependencies for.
- cache_dir: Primarily for bots, multiple working sets use a single git
cache.
gclient is necessary for checking out the flutter-engine source code, as the
release tarballs provided on the flutter-engine github are in no state to
compile. Google expects the use of gclient to download a source directory
structure suitable to build the Flutter engine.
