I don't understand why. In my terminal stack repl is available

[rikvdkleij]

It looks like you hit this bug:
commercialhaskell/stack#2603

I have created workaround for this issue but apparently it does not work for you.

In the meantime it is fixed in master.
Can you try to upgrade Stack to master by:
stack upgrade --git

[xgrommx]

@rikvdkleij The same problem. My Stack Version 1.2.1, Git revision 7e31cd80e2394811ab62bf11295bfdfcf2d7c4d7 x86_64 hpack-0.14.1 and I use latest version of EAP of IDEA 2016

[rikvdkleij]

Can you show me complete Event log?

Did you reconfigure path to Stack? So you are sure latest version of Stack is used by IntelliJ.

Also check Intero is on your path.
stack exec -- which intero

[xgrommx]

@rikvdkleij What do u mean about? Did you reconfigure path to Stack? So you are sure latest version of Stack is used by IntelliJ. I have available stack in my terminal.

I mean before importing Haskell project you have to set path to folder where stack is installed.

If your project is already imported, take a look to module settings and Haskell Tool Stack setting.

[rikvdkleij]

[global-stack-repl] The following GHC options are incompatible with GHCi and have not been passed to it: -threaded /Users/gromm/.stack/programs/x86_64-osx/ghc-8.0.1/lib/ghc-8.0.1/package.conf.d/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (not enough bytes)

This means Intero is build with other GHC version as project.

See .5 of Remarks in Readme.

[xgrommx]

@rikvdkleij I found problem! I have several versions of ghc. And for my case I need install stack install intero --resolver lts-7 because I use ghc-8 by default.

[xgrommx]

@rikvdkleij Oh man! I like this plugin! This is first plugin which works with stack!

[rikvdkleij]

@rikvdkleij I found problem! I have several versions of ghc. And for my case I need install stack install intero --resolver lts-7 because I use ghc-8 by default.

Great! Or better, in root folder of project stack build intero Because using install will install it globally. You do not want that if you have projects with different GHC versions.

I do not know how to make this robust.

It's also issue for haskell-docs.

[rikvdkleij]

@rikvdkleij Oh man! I like this plugin! This is first plugin which works with stack!

Thanks!

[rikvdkleij]

Maybe solution is when importing/starting project to build intero and haskell-docs so they are always compatible with GHC-version of your project.

[xgrommx]

@rikvdkleij Do u have some plan to port some features like here http://haskforce.com/ ? For example Automatically add type signatures

[rikvdkleij]

It's already there, an intention action, ctrl + enter

[xgrommx]

@rikvdkleij ok, but what is on Mac?

[xgrommx]

ctrl + enter is just smart split.

[rikvdkleij]

Sorry, it's alt + enter

[unthingable]

I've been unable to get it to add a type signature. Intero REPL is started successfully, hlint is configured, this is happening with both 1.0 beta and beta2. Nothing is happening upon alt-enter, and no Haskell intentions are listed in IDEA settings (is that normal?). Meanwhile, when I hit alt+enter, I do see the type signature spit out by the REPL in the event log!

[rikvdkleij]

The type signature is extracted from compiler warning.

Can you give me the type signature that is spit out by Repl?

[unthingable]

Sure. Hitting alt-enter on a line foo = 1:

13:28   [project-stack-repl] command: :type-at /Users/[...]/src/Main.hs 58 1 58 4 foo

13:28   [project-stack-repl] stdOut: foo :: Integer

[unthingable]

"The type signature is extracted from compiler warning." — after rereading that a forehead smack is appropriate. GHC warnings have been turned off. Added -Wall to ghc-options in .cabal and now it works.

[JonasTaulien]

On my PC (Debian Jessie) I had to 'sudo apt-get install libtinfo-dev' and re-import the project. After that the repl was running successfully :)

[overdeliver]

I ran into this, too. Had to 'sudo apt-get install ncurses-dev' then did 'stack build terminfo' and 'stack build intero', in the root of the project, then opened up IntelliJ to find everything working. This was after I did a: 'stack upgrade --git' as suggested earlier.

[rikvdkleij]

@overdeliver So plugin works?
