| # We combine the tags generated for GHC registry with ones for DockerHub. We do this by using sed to replace | |
| # appearances of ghcr.io with docker.io in the original tags. The combination of the original tags plus the | |
| # sed calculated ones are combined and stored as a multiline string in a new env var. | |
| # | |
| # Some things to note | |
| # - each line of the HEREDOC must output something. That is why we call 'echo' in each one | |
| # - steps.meta.outputs.tags is itself a multiline string so we must wrap the call in quotes else the second line | |
| # of the string is interpreted as a command | |
| # - GitHub action's `set-output` truncates multiline strings which is why we have resorted to what you see below | |
| # to get a value which contains all the possible tags as a multiline string | |
| # - the 'if' determines if this is a push to `main` or a new tag. If a push to `main` we add a unique tag, for | |
| # example `v0.13.2-2-g9ce6d11`. This is to support testing | |
