By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.

:warning: The command is written for posix shells. You can copy the contents of each perl command excluding the outer ' marks and dropping any '"/"' quotation mark pairs into a file and then run perl file.pl from the root of the repository to run the code. Alternatively, you can manually insert the items...

If the listed items are:

• ... misspelled, then please correct them instead of using the command.
• ... names, please add them to .github/actions/spelling/allow/names.txt.
• ... APIs, you can add them to a file in .github/actions/spelling/allow/.
• ... just things you're using, please add them to an appropriate file in .github/actions/spelling/expect/.
• ... tokens you only need in one place and shouldn't generally be used, you can add an item in an appropriate file in .github/actions/spelling/patterns/.

See the README.md in each directory for more information.

:microscope: You can test your commits without appending to a PR by creating a new branch with that extra change and pushing it to your fork. The check-spelling action will run in response to your push -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. :wink:

well-formed pattern

See if there's a pattern that would match it.

If not, try writing one and adding it to a patterns/{file}.txt.

Patterns are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your lines.

Note that patterns can't match multiline strings.

binary-ish string

Please add a file path to the excludes.txt file instead of just accepting the garbage.

^ refers to the file's path from the root of the repository, so ^README\.md$ would exclude README.md (on whichever branch you're using).

I've added a commit to this on my fork of the terminal that no longer extends from std::map - https://github.com/ianjoneill/terminal/tree/dev/miniksa/env. Should I open another MR or is there some way of linking my branch with this MR?

I've added a commit to this on my fork of the terminal that no longer extends from std::map - ianjoneill/terminal@dev/miniksa/env. Should I open another MR or is there some way of linking my branch with this MR?

Honestly, I'd recommend just filing a new one, I think that'd be the easiest way to iterate and get this in. Thanks!

Superseded by @ianjoneill's (excellent) work. Thanks Michael!
