feat: add args input

[znd4]

Adds args input to allow for passing arbitrary additional arguments to dprint check

Alternatives considered

Add specific inputs for the things that I need:

• files
• --excludes
• --allow-no-files

LGTM Thank you!

Could you document this in the README briefly?

[znd4]

thanks for the quick review! Does the example I added work? (It's the actual usecase I need it for)

[thomaseizinger]

Yep that should work, just one clarifying syntax question :)

[thomaseizinger]

Suggested change

	args: >-
	--allow-no-files
	${{ steps.changed-files.outputs.all_changed_files }}
	args: |
	--allow-no-files
	${{ steps.changed-files.outputs.all_changed_files }}

I am not familiar with that yaml syntax, does a multi-line string also work?

[znd4]

> makes it so that lines are separated with spaces instead of newlines, such that

a: >
  b
  c

Becomes

{"a": "b c\n"}

- chomps the trailing newline.

I use https://yaml-multiline.info/ ~ once per month for silly yaml features like this

I think the problem with | here is that it would end up with the command

dprint check --allow-no-files
file1 file2 ...

It is cool and scary at the same time that yaml supports this. Thanks for explaining!

What is with all this whitespace here?

[znd4]

good catch
