    new-host-10:HaskellProject barryburd$ stack new Project1
    Downloading template "new-template" to create project "Project1" in Project1/ ...

    The following parameters were needed by the template but not provided: author-email, author-name, category, copyright, github-username
    You can provide them in /Users/barryburd/.stack/config.yaml, like this:
    templates:
    params:
    author-email: value
    author-name: value
    category: value
    copyright: value
    github-username: value
    Or you can pass each one as parameters like this:
    stack new Project1 new-template -p "author-email:value" -p "author-name:value" -p "category:value" -p "copyright:value" -p "github-username:value"

    Looking for .cabal or package.yaml files to use to init the project.
    Using cabal packages:

    • Project1/Project1.cabal

    it might just be that it was the first time stack was set up and so it took too long or something
    haskforce should give better feedback in that regard

    @carymrobbins
    so i'd recommend just creating the stack project on the command line and importing it into haskforce
    since these will be mostly new folks using the tools
    i could also look into improving the way the new project wizard works
    for new systems

    Question: Does haskforce support typed holes?
    Cary Robbins
    @carymrobbins
    (assuming that's the issue)
    Barry Burd
    @allmycode_twitter
    I still keep getting that AesonException "Error in $.packages.cassava.constraints.flags: on the command line on the Mac.
    Cary Robbins
    @carymrobbins
    @allmycode_twitter oh that seeems like some issue with stack
    Barry Burd
    @allmycode_twitter
    I'll try reinstalling stack on the Mac
    Cary Robbins
    @carymrobbins
    @allmycode_twitter this issue sounds familiar...may be worth a google
    @reggieperry nothing stops you from using type holes, although i recently added parser support for them so they won't appear red in the IDE. that will be released soon.
    Reggie Perry
    @reggieperry
    The reason I ask is because typed holes with the new valid-hole-fits feature would be very powerful in IntelliJ to aid in type driven development. I would be curious as to how tough that would be to implement in haskforce.
    Cary Robbins
    @carymrobbins
    @reggieperry haskforce currently has ghc-mod integration, and i believe ghc-mod provides something like this (the refine command)
    i'm not sure if this completely handles your use case, feel free to open a feature request on the haskforce issue tracker. i'll be able to add details there about what may be needed for implementing this
    Cary Robbins
    @carymrobbins
    oh and -frefinement-level-hole-fits looks interesting as well
    Barry Burd
    @allmycode_twitter
    @carymrobbins You said "the Haskell Stack Run is for running your compiled binary, not for running ghc" so I get "Executable named ... not found on path". I don't see any executable that's been created in any of the project directories.
    Cary Robbins
    @carymrobbins
    @allmycode_twitter Right, so first your build must succeed. Your binary name is defined in your cabal file (or package.yaml). The analogous workflow on the command line would be -
    $ stack build
$ stack exec <compiled-executable-name-from-cabal-file>
    if stack build fails, you can't exec the binary because it doesn't exist yet
    Barry Burd
    @allmycode_twitter
    I thought I already had a successful build after importing a project that I created on the command line, but I'll keep poking around.
    Cary Robbins
    @carymrobbins
    to debug this, what is the result of stack build from the command line?

    @carymrobbins
    btw you can wrap the output in triple backticks to make it easier to read 
    like this
    that said 
    Installing executable HaskForceCreatedWithStackCommand-exe in ...
    so you want to run 
    stack exec HaskForceCreatedWithStackCommand-exe
    Barry Burd
    @allmycode_twitter
    OK. Got to go now but I'll try it (and I'll use backticks in the future where necessary). Thanks.
    Cary Robbins
    @carymrobbins
    sounds good. last thing - in haskforce the executable name is HaskForceCreatedWithStackCommand-exe
    the name is defined in your cabal file
    Reggie Perry
    @reggieperry
    @carymrobbins Will do. Thanks.

    @develop7
    hey @carymrobbins, are there any plans on adopting Eta for plugin development?
    Rahul Muttineni
    @rahulmutt
    @develop7 @carymrobbins was working on the Eta Intellij plugin which is written (in as much as Eta’s interop features allow) in Eta itself. A lot of it took inspiration from haskforce code, so when Eta can compile GHC & support more interop features, haskforce should be able to use Eta completely w/o depending on other languages.
    The core plugin code that’s written in Eta is here: https://github.com/typelead/intellij-eta/tree/master/plugin/src/main/eta/IntelliJ/Plugin
    Andrei Dziahel
    @develop7
    @rahulmutt got it, thanks!
    Cary Robbins
    @carymrobbins
    @rahulmutt @develop7 The most recent stuff i think is in the eta-ide branch. There's also some Psi parser combinators for building intellij parsers which is pretty nice.
    Andrei Dziahel
    @develop7
    @carymrobbins @rahulmutt I've skimmed through source and there are a lot of reimports of IDEA SDK.
    Rahul Muttineni
    @rahulmutt
    @develop7 Yes, that’s the FFI boilerplate for binding against the required SDK APIs - we’re currently working on removing the boilerplate with some new features in Eta itself. There should be some modules that actually do something.
    Cary Robbins
    @carymrobbins
    @develop7 here's the psi parser combinator, for a non-ffi example - https://github.com/typelead/intellij-eta/blob/eta-ide/plugin/src/main/eta/IntelliJ/Plugin/Eta/Lang/Parser/EtaPsiParser.hs
