| # This is a vpython "spec" file. |
| # |
| # It describes patterns for python wheel dependencies of the python scripts in |
| # the chromium repo, particularly for dependencies that have compiled components |
| # (since pure-python dependencies can be easily vendored into third_party). |
| # |
| # When vpython is invoked, it finds this file and builds a python VirtualEnv, |
| # containing all of the dependencies described in this file, fetching them from |
| # CIPD (the "Chrome Infrastructure Package Deployer" service). Unlike `pip`, |
| # this never requires the end-user machine to have a working python extension |
| # compilation environment. All of these packages are built using: |
| # https://chromium.googlesource.com/infra/infra/+/master/infra/tools/dockerbuild/ |
| # |
| # All python scripts in the repo share this same spec, to avoid dependency |
| # fragmentation. |
| # |
| # If you have depot_tools installed in your $PATH, you can invoke python scripts |
| # in this repo by running them as you normally would run them, except |
| # substituting `vpython` instead of `python` on the command line, e.g.: |
| # vpython path/to/script.py some --arguments |
| # |
| # Read more about `vpython` and how to modify this file here: |
| # https://chromium.googlesource.com/infra/infra/+/master/doc/users/vpython.md |

| python_version: "3.8" |
| |
| # TODO(https://crbug.com/898348): Add in necessary wheels as Python3 versions |
| # become available. |
