Tools for ChromeOS development on linux.

This directory contains tools that are useful when developing ChromeOS UI on linux.

run_cros.sh

run_cros.sh is a shell script to ash-chrome on linux, with a set of useful predefind options (e.g. enables login, debug shortcuts and ui-devtools) with optional customization (e.g. display settings).

  $ tools/chromeos/run_cros.sh

will run the chrome in out/Release directory with default settings. You may add src/tools/chromeos directory to your PATH and can simply run it without the path.

  $ run_cros.sh

If the directory for your local build is different from the default, you can override it with --ash-chrome-build-dir.

  $ run_cros.sh --ash-chrome-build-dir=<dir_to_your_chrome_binary>

Please use --help to show more options.

  $ run_cros.sh --help

Lacros support

You can also run lacros in this environment. There is no option to download prebuilt Lacros, so you first have to build your own lacros. If you use the default build directory out/lacros, and then you can simply run

  $ run_cros.sh --enable-lacros

You can override the lacros build directory using --lacros-build-dir and you can omit --enable-lacros.

  $ run_cros.sh --lacros-build-dir=out/lacros_out_dir

Environment variables

You can set the following environment variable instead of using command line flag.

ASH_CHROME_BUILD_DIR : specifies the directory for --ash-chrome-build-dir

LACROS_BUILD_DIR : specifies the directory for --lacros-build-dir
