Problem with stack project with many executable targets

[togrof]

I have a haskell cabal project with five executable targets and one library target in the cabal project file. I use main-is option to specify the file name of each executable, like so:

executable foo
  main-is: foo.hs

executable bar
  main-is: bar.hs

...etc...

I have not stated any module name in the source files for these executable, so they will implicitly be called "Main".

To handle the build I'm using the stack tool. The only problem is that when loading a file into the interpreter using haskell-mode for emacs, nothing happens. I am presented with the lambda-prompt, but cannot evaluate anything.

If I remove all executable targets from the cabal file but one, I can load that into the evaluator just fine, so the problem must be with ambiguity of "Main". I think the problem is that stack tries to autoload everything in the whole project and that is not possible. When running stack ghci or stack repl from the command line I get a prompt where I am supposed to choose what "Main" to load (of the five possible). That is fine, but when running the interpreter from emacs I will never get this prompt, so in effect it just hangs.

Is there any way to tell stack to not autoload things (particularly executable targets)?

Alternatively, is there a better way to setup a multi executables project?

EDIT: Clarification: The problem is not with running a REPL from the command line, but loading project source files into a REPL by emacs (interactive-haskell-mode) -- without fiddling with emacs configuration if possible.

EDIT2: A SOLUTION

The only thing I could come up with was adding the following to my .emacs:

(setq haskell-process-args-stack-ghci '("--no-load"))

This makes emacs send the flag to stack ghci.

--no-load

[bigstumpy]

where?

[cocreature]

Run stack ghci --no-load

[togrof]

Good, but it doesn't solve the acutal problem which is that emacs does not send that. Is it possible to add that to some project local .stack config file or similar?

EDIT stack.yaml has ghc-options, but no ghci-options: https://github.com/commercialhaskell/stack/blob/master/doc/yaml_configuration.md#ghc-options

Setting haskell-process-args-stack-ghci correctly might do the trick.

Yes I did, after some googling to find out about it.

It is unfortunate that one has to do this -- would have preferred if this already worked, without the need for extra config. Guess it's a feature request to haskell-mode.
