How can I run a formatting check in the CI? I need a command that exits !=0 in case reformatting was necessary. There is the

lint

target, however this also runs all linters and I cannot distinguish whether any !=0 exit code stems from a linter or a formatter.

Have you looked at permutations with

--[no-]lint-skip-formatters

? https://www.pantsbuild.org/2.18/reference/goals/lint

Yes, but the available settings don't do what I need. There is

skip_fixers

and

skip_formatters

but I need

skip_linters

. It might sound confusing to run

pants lint --lint-skip-linters

but as

lint

runs linters as well as formatters/fixers this would make sense to me. Or is that possible and I overlooked something?

I think you could do

--lint-only=[]

, albeit while manually making this list

I just discovered that pants

2.20.0rc0

now splits ruff into 2 lint parts:

ruff-check

and

ruff-format

. Together with your advice

lint-only

I can achieve my goal:

pants lint --lint-only="['ruff-format']" <target>

Thanks!
