"""
Prepares CEF binaries and libraries for work with the build.py tool.
Option 1 is to build CEF from sources with the CEF Python patches applied
using the --build-cef flag.
Option 2 is to use CEF binaries from Spotify Automated Builds using
the --prebuilt-cef flag. In such case check the cefpython/src/version/
directory to know which version of CEF to download from Spotify:
http://opensource.spotify.com/cefbuilds/index.html
Download and extract it so that for example you have such a directory:
cefpython/build/cef_binary_3.2883.1553.g80bd606_windows32/ .
This tool generates CEF binaries and libraries that are ready for work
with cefpython, with the build.py script. When automate.py tool completes
job you should see a new subdirectory in the build/ directory, for example:
cefpython/build/cef55_3.2883.1553.g80bd606_win32/ .
Usage:
automate.py (--prebuilt-cef | --build-cef)
[--fast-build FAST_BUILD]
[--force-chromium-update FORCE_CHROMIUM_UPDATE]
[--no-cef-update NO_CEF_UPDATE]
[--cef-branch BRANCH] [--cef-commit COMMIT]
[--build-dir BUILD_DIR] [--cef-build-dir CEF_BUIL_DDIR]
[--ninja-jobs JOBS] [--gyp-generators GENERATORS]
[--gyp-msvs-version MSVS]
automate.py (-h | --help) [type -h to show full description for options]
Options:
-h --help Show this help message.
--prebuilt-cef Whether to use prebuilt CEF binaries. Prebuilt
binaries for Linux are built on Ubuntu.
--build-cef Whether to build CEF from sources with the
cefpython patches applied.
--fast-build Fast build with is_official_build=False
--force-chromium-update Force Chromium update (gclient sync etc).
--no-cef-update Do not update CEF sources (by default both cef/
directories are deleted on every run).
--cef-branch= CEF branch. Defaults to CHROME_VERSION_BUILD from
"src/version/cef_version_{platform}.h".
--cef-commit= CEF revision. Defaults to CEF_COMMIT_HASH from
"src/version/cef_version_{platform}.h".
--build-dir= Build directory.
--cef-build-dir= CEF build directory. By default same
as --build-dir.
--ninja-jobs= How many CEF jobs to run in parallel. To speed up
building set it to number of cores in your CPU.
By default set to cpu_count / 2.
--gyp-generators= Set GYP_GENERATORS [default: ninja].
--gyp-msvs-version= Set GYP_MSVS_VERSION.
