Action Add Labels

This is a GitHub Action to add GitHub labels to an issue or a pull request.

This action extract the number from an issue or a pull request which has triggered this by default. It means you don't need to care about something annoying like whether you should use ${{ github.event.issue.number }} or ${{ github.event.pull_request.number }}.

It would be more useful to use this with other GitHub Actions' outputs.

Inputs

NAME	DESCRIPTION	TYPE	REQUIRED	DEFAULT
github_token	A GitHub token.	string	false	${{ github.token }}
labels	The labels' name to be added. Must be separated with line breaks if there're multiple labels.	string	true	N/A
number	The number of the issue or pull request.	number	false	N/A
repo	The owner and repository name. e.g.) Codertocat/Hello-World	string	false	${{ github.event.issue.number }} or ${{ github.event.pull_request.number }}
