| To build Dart for Mac and Linux, we pull Fuchsia's buildtools, which is also |
| used by Flutter. Fuchsia's buildtools includes gn, and the clang toolchain. |
| Fuchsia buildtools vends clang-format as part of the clang toolchain. Since |
| Fuchsia's buildtools doesn't vend a clang toolchain for Windows, we can't |
| get a Windows clang-format binary from it. Therefore, from Chromium's buildtools |
| here: |
| |
| https://chromium.googlesource.com/chromium/buildtools |
| |
| we copy the hash file for its Windows clang-format binary, and pull it down |
| from google storage in the update.py script in this directory. |
| |
| To update to a newer Windows clang-format binary, simply overwrite the hash in |
| clang-format.exe.sha1 with a newer one, and then do a 'gclient sync'. |
