Regression: C-c C-l keeps asking for a new session for different files within the same project

[ozataman]

Even after starting a session called project for project/Foo.hs, C-c C-l keeps asking whether we should start a new project named project for each newly introduced file under the same project.

This broke only recently (unless it was done by design, in which case I would ask that we create a flag to enable/disable it).

Hmm. It would be surprising if there's a regression here; nobody touches that session code, not since last year.

Can you reduce it to a test-case of a few files that I can reproduce exactly locally?

[chrisdone]

@ozataman I just pushed a change c8a72bd which fixes a bug where when picking a session for a file, if there is an incomplete session which doesn't have a cabal-dir assigned to it yet, it will prompt for a cabal dir—which would then assign that directory to that incomplete session, even though you already had another session next on the list which would've been the right candidate. This made it pretty hard to reproduce when it happened so it's taken me a while to both notice it and be in a position to investigate it. Maybe this is the behaviour you were experiencing here.

Good to know, thank you. I'll pull and see if I see it again. I've
definitely been experiencing this quite often, but just haven't been able
to pin down exactly when/why it happened.

There is also sometimes I think I've noticed a prompt for a project I was already in, but it's rare enough that I haven't noticed and am not sure it actually exists as a bug. If I see it again I'll pin it down and fix it.

[chrisdone]

Oh, there it is! It's not quite as I described, but it's as I remembered. For some reason, calling M-x haskell-session-change makes it say Start new project named “projecti'malreadyin”? (y or n). I'll fix that.

[chrisdone]

Okay, fixed that. I wonder if this'll fix this issue.

[sindikat]

How is it possible to make haskell-mode not to ask about starting a new project at all? I just want C-c C-l simply load the code into the inferior process and nothing more.

[gracjan]

If I understand correctly original issue is resolved. If not do not hessitate to leavea note here.

As for the other request to simplify C-c C-l behavior there was a pull request about it #409.
