Is there any way to run

update-build-files

on a subset of files? I want to run it in a pre-commit hook as a formatter, but having it run over the entirety of the repository causes commits to be extremely slow. From https://www.pantsbuild.org/docs/reference-update-build-files, I see:

This goal is run without arguments. It will run over all BUILD files in your project.

So it looks like in Pants 2.14 you can (and are actually forced) to use arguments. You might try it and see if it works with your Pants version today.

The following command seems to still run on all files as of Pants 2.11 😞

./pants --changed-since=origin/master update-build-files

Ah yeah you can probably get really clever by running some shell command to revert changes to

BUILD

files that werent changed in this branch 🤷‍♂️

How many files and directories are there in your project? I'm assuming it'll glob through, but isn't it only acting on a single file per directory (at most?). I'm more surprised it's slow, than anything else

My codebase is extremely large—it’s the codebase for my entire company, and we have a monorepo

This was fixed in 2.13 as a flagship feature 🙂

./pants --changed-since=HEAD update-build-files

does what you would expect, and then you use normal CLI args like

./pants update-build-files ::

or

./pants update-build-files dir1

Great, thanks so much! Very excited for this
