Specify target with new-repl

[cah6]

Status

• A workaround is available
• A fix is written
• A fix is released
• The fixed verison is on the marketplace.

---

• Version of vscode-ghc-simple: 0.1.10
• Version of VSCode: 1.33.1
• Version of Haskell-related tools:
  • GHC: 8.4.3
  • Cabal: 2.2.0.0

Steps to reproduce

Given the workspace, launch VSCode in the nix shell with nix-shell -A shells.ghc --run "code .".

I found that you can force cabal new-style commands by setting "workspaceType" to "cabal new", but this doesn't work out of the box with multi-folder repositories. Notably, for these repositories the command needs to be cabal new-repl all. Is there a way to specify more arguments that will be passed through to the cabal launch?

Note that to work around this you can just set workspaceType to "cabal" to use cabal repl instead, but I would like to try getting the new-style commands to work.

Hi there,

You're in luck; I wrote this up just yesterday before seeing your issue! See #34

Nice! That looks like exactly what I needed.

I have to say I'm not familiar with how cabal works, especially the new-build part.

Is cabal new-repl all supposed to always select all targets? If so I'm going to actually make that the default, since it's actually what I do for stack.

@dramforever I think so! There might be some edge case I don't know about, but it looks like it selects all for single cabal file projects (where the cabal file is in the root, no .project file), and multiple cabal file repositories, where the .project file points to multiple sub-directories.

v0.1.11 now uses target all by default (cabal {new,v2}-repl all) and allows customizing the REPL command with ghcSimple.replCommand and ghcSimple.replScope. If this version does not solve this problem or causes other problems, please feel free to reopen this issue or raise a new one.
