Recommended way of building and deploying plugins

[jrp2014]

When I am building and testing a plugin project, I can just add the plug-in library to dependency of the executable I am testing in the project, and add -fplugin to the ghc-options and things work.

If I (v2) install the plugin library I can't find a way of easily getting hold of it in other projects. Adding it to the dependencies of the other project helps, but

• I can't seem to find a way of applying the plugin-in to only the exposed modules, and not the build-depends.
• As well as -fplugin I seem to have to add -package to even get that far, as otherwise the package / plugin is reported as hidden.

I have looked through some of the earlier issues, but did not find a solution.

Is there an example or further documentation anywhere that might provide some pointers?

Many thanks.

The story with plugin support definitely could be improved. In ghc-tags-plugin I recommend this setup. Not ideal as one needs to provide -package-db where the plugin is installed which depends on the ghc version, and tooling.

There's a related ticket which asks for support of -fplugin-package support: #6169.
