Hi guys, what’s the difference between

./pants tailor --check update-build-files --check

and

./pants tailor --check

?

Hi.

update-build-files

formats BUILD files and also checks for deprecations that can be safely fixed, like renaming target fields @bitter-ability-32190 has been doing great work to get rid of

update-build-files

in favor of the

fmt

and new

fix

goals.

fmt

will run Black or Yapf on the files, and

fix

will do the deprecation fixes. 2.14 has the

fmt

support, and 2.15 will have

fix

Ok, but since we are using

--check

it will just inform us what needs to be fixed and if any BUILD files are missing (

tailor --check

)….right?

yeah, so

tailor --check update-build-files --check

is short hand for

--tailor-check --update-build-files-check tailor update-build-files

. That is, you are saying to run both the goals

tailor

and

update-build-files

, and for both you are setting their

--check

options
