1# This is a vpython "spec" file. 2# 3# It describes patterns for python wheel dependencies of the python scripts in 4# the chromium repo, particularly for dependencies that have compiled components 5# (since pure-python dependencies can be easily vendored into third_party). 6# 7# When vpython is invoked, it finds this file and builds a python VirtualEnv, 8# containing all of the dependencies described in this file, fetching them from 9# CIPD (the "Chrome Infrastructure Package Deployer" service). Unlike `pip`, 10# this never requires the end-user machine to have a working python extension 11# compilation environment. All of these packages are built using: 12# https://chromium.googlesource.com/infra/infra/+/master/infra/tools/dockerbuild/ 13# 14# All python scripts in the repo share this same spec, to avoid dependency 15# fragmentation. 16# 17# If you have depot_tools installed in your $PATH, you can invoke python scripts 18# in this repo by running them as you normally would run them, except 19# substituting `vpython` instead of `python` on the command line, e.g.: 20# vpython path/to/script.py some --arguments 21# 22# Read more about `vpython` and how to modify this file here: 23# https://chromium.googlesource.com/infra/infra/+/master/doc/users/vpython.md 24 25python_version: "2.7" 26
