name: Pull Request Checks

# Workflow triggers either manually or by creating or editing a comment on a pull request. When triggering manually, a pull request ID is required. Apart from that, a comment must 
# be provided. When commenting on a PR, the comment is first checked to start with `Run:`. If this evaluates to true, the rest of the comment is checked to contain either of the
# supported commands. Those are:
#
# - `tests`: runs tests
# - `tidy`: runs static code analysis
# - `checks`: runs everything of the above.
#
# Commands are restricted to be issued by maintainers or previous contributors.
# Note that commands are case-sensitive. Also note that you could do wild shenanigans with this, like writing poems containing command keywords after the `Run:` string, but for the
# sake of brevity please refrain from doing so! :-)

# The following jobs are contained in this workflow:
# - First, the `verify-permissions` job is executed. It checks if the comment user is a contributer or maintainer and if the comment refers to a pull request. It then parses the 
# command string. If permission is granted, the result is then passed to the subsequent jobs, which only execute if this job outputs their respective launch command.
# - The `tests` job executes the tests.
# - The `tidy` job executes static code analysis.
