cabal: Add necessary aliases for vendored packages with executables #2309
Conversation
This allows vendoring of packages with necessary tools from a stack snapshot. For example, if the cabal file for `cpphs` hasn't yet been bumped on hackage with increased bounds for the newest ghc.
There was a problem hiding this comment.
Thank you!
It took me a while to figure out what's going on; so for posterity and to remind myself:
For stack_snapshot there will be a repository called stackage (let's say) and for each of the library components there will be a haskell_cabal_library target.
For exe components, there will be a haskell_cabal_binary target (called _<name>_exe_<exe-name>). But also, there will be an alias (just exe-name) in the stackage-exe repository pointing to the actual haskell_cabal_binary in stackage.
For vendored packages, the haskell_binary_target does not exist in stackage, so this needs another alias pointing to the actual exe target in the repository of the vendored package.

@iteratee somehow CI failed and I cannot seem to retry it. Could you please rebase and re-push your branch? |
