Backport
This PR is auto-generated from #16174 to be assessed for backporting due to the inclusion of the label backport/1.4.x.
The below text is copied from the body of the original PR.
Fixes #16170
The
nomad fmt -check
command incorrectly writes to file because we didn'treturn before writing the file on a diff. Fix this bug and update the command
internals to differentiate between the write-to-file and write-to-stdout code
paths, which are activated by different combinations of options and flags.
The docstring for the
-list
and-write
flags is also unclear and can beeasily misread to be the opposite of the actual behavior. Clarify this and fix
up the docs to match.
This changeset also refactors the tests quite a bit so as to make the test
outputs clear when something is incorrect and avoid reusing the UI state.
