Launching with cabal new-repl doesn't work #10

Open sloane-shark opened 5 years ago

I'm attempting to use haskell-dap (0.0.13.0), phoityne-vscode (0.0.28.0) along with the phoityne-vscode extension with GHC 8.6.5 to debug code. When I run cabal new-repl --with-ghc=haskell-dap, I get an error like

Warning: cannot determine version of
/nix/store/i9wdlh5hxk93r0c7hhhjw1axrhydk81j-ghc-8.6.5-with-packages/bin/ghci-dap
:
"[DAP][INFO] start ghci-dap-0.0.12.0.\n8.6.5\n"
cabal: The program 'ghc' version >=7.0.1 is required but the version of
/nix/store/i9wdlh5hxk93r0c7hhhjw1axrhydk81j-ghc-8.6.5-with-packages/bin/ghci-dap
could not be determined.

Is there any special set up needed to use this program with cabal new-* style commands? Is it compatible?

Hi.

Thanks for your report. I will check cabal new-* style commands. (never tried so far.)

From your log, seems like that the current version might not work.

Regards.

Could you try this command in the cabal project directory to start repl ?

$ cabal new-exec -- ghci-dap --interactive

And set ghciCmd variable in the launch.json file as below, when using with vscode.

"ghciCmd": "cabal new-exec -- ghci-dap --interactive -i${workspaceRoot}/src",

Regards.
