TestFlags are not saved in ~/.cabal/config and must be passed by command line.

Hello, I would like this feature implemented. What are the blockers for this feature?

[ulysses4ever]

@Abastro no particular blocker afaik, we just need a volunteer to work on it: there's currently none, it seems.

[Abastro]

@ulysses4ever Oh, is this one hard to implement?
It seems like the linked Cabal/Distribution/Simple/Setup.hs no longer exists, so I guess it would be done a bit differently?

[Mikolaj]

Probably not that hard and, in any case, worth a PR, with a test, with some experiments, and then we'd see how to goes.

I'd guess it's this file?

~/r/cabal$ find . -name "*Setup.hs"
./cabal-dev-scripts/Setup.hs
./Cabal/src/Distribution/Simple/Setup.hs
...

[Mikolaj]

BTW, things like --show-details=always from the original request now go into cabal.project and work fine. But perhaps not everything does; worth checking.

[Abastro]

Oh. The behavior seems not documented, so I assumed it does not exist.. Thanks a lot!

[ulysses4ever]

I'm guessing that if it works from a project file, than it should work from the config file too? (Although, this is not at simple in general #6319)

[Abastro]

Can I ask where I could find list of options supported by cabal.project.local in the documentation?

@Abastro

Can I ask where I could find list of options supported by cabal.project.local in the documentation?

In the manual: 7. cabal.project Reference.

By the way, I tried to put it in ~/.cabal/config instead of cabal.project.local -- and it didn't work. This is surprising to me, as many options work from either of the files.

[Abastro]

I do not see test-show-details in the list, while it is a valid option in cabal.project.local. Maybe documentation should be updated to reflect the options?

[ulysses4ever]

Correct: the manual is in no way complete. (What's even funnier is that --test-show-details is not documented at all! #8619) The rule is thumb is that whatever goes on command line can go to cabal.project(.local) in some form.
