Mk/Uses/cabal.mk: Support for USE_CABAL in separate Makefile.cabal

[alven]

Summary

Like we already do have in Mk/Uses/cargo.mk for Makefile.crates

• Adopt www/hs-postgrest to this change in framework.

I find .modules part to be confusing. Rust names it .crates, so we probably should call it .cabal

Mk/Uses/cabal.mk

3) make make-use-cabal > Makefile.modules

crate => crates
cabal => cabals

[arrowd]

Cabal is a package manager name and a file format, so no, plural seems unfitting there.

Anyone from portmgr@: please come and help us with this simplest task... :)

[alven]

Up, please...

[arrowd]

If you want an approval from me then I'd like to see the file named Makefile.cabal, not .modules.

[alven]

Use filename 'Makefile.cabal'

@alven What do you think about this comment? ^

[arrowd]

Given that you verified that this actually works, LGTM.

You can also adapt www/hs-postgrest to make use of this feature.

[alven]

Thank you! What now?

Was just a mistake you've repeated after me? :)
I've fixed it to what you like now. It was all that simple, yes? :)

[arrowd]

[alven]

Thank you! :)

This stopped to work with newer versions of cabal, which tends to parse Makefile.cabal as a common .cabal file:

Errors encountered when parsing cabal file ./Makefile.cabal:

Makefile.cabal:0:0: error:
"name" field missing

May we choose another file extension for it, please?

[arrowd]

How do I reproduce the problem?

[alven]

cd /usr/ports/default/www/hs-postgrest && make cabal-extract
