A GitHub Action to check whether a conda package has a recent release candidate.

This was designed to test against requirements that publish release candidates to a conda channel. In general, you won't need to do nightly builds against the most recent release candidate every night, but you don't want to miss when an RC is posted.

This workflow checks whether a release candidate has been added within the last ndays days. It sets the value of its output hasrc, to either the string 'True' if such an RC is present, or the string 'False' if not.

The assumption is that you'll create a scheduled workflow that calls this action, and depending on the result, triggers some other workflow. An example of this is in .github/workflows/example_use.yml.

Required Channel where the package is found. Default 'conda-forge'. Note: if using the "defaults" channel, you must actually specify which specific channel the package comes from ('main', 'r', etc.) Verify that there is a page at https://anaconda.org/$CHANNEL/$PACKAGE.

Required Package name.

Required Max number of days to search for release candidates. Default 7.

Required Space-separated list of conda labels where RCs are found. Default main.

Whether there is a release candidate for this package. The string 'True' if there is one; 'False' if not.
