haskell-ghc-mod's Introduction

Deprecation & archival notice

GHC-Mod has been unsupported for several years now. This package still might work with older GHC releases (where GHC-Mod still works), but overall its usefulness is questionable. Hence, this repository is deprecated and archived.

If you want to discuss haskell-ghc-mod, feel free to open an issue on https://github.com/atom-haskell/ide-haskell/issues.

haskell-ghc-mod atom package

This package is primarily intended as backend for ide-haskell.

Haskell ghc-mod opens pipe to ghc-modi and queries types, info and checks for errors.

Installation and configuration

Please refer to the official documentation site https://atom-haskell.github.io

Service-hub API

Since 1.0.0, haskell-ghc-mod provides haskell-completion-backend service.

NOTE: Prior to 1.0.0, ide-backend service was provided. It has been scrapped in favor of ide-haskell's UPI.

You can find description in src/completion-backend/index.ts

fails to recognize bash PATH for ghc-mod / ghc-modi

I had tested this originally when installing ghc-mod via cabal and now with installing via stack. In both cases, I have ghc-mod on my bash PATH, i.e. I can run "which ghc-mod" and see the path and also can simply run "ghc-mod" with no path specified anywhere in bash and it works. It is on my path.

However, haskell-ghc-mod says that it can't find ghc-mod and ghc-modi unless I go to the settings and provide the path explicitly. So, the default path of just ghc-mod (thus deferring to the path known by bash) is not working.

Uncaught Error: Error: Command failed: ghc-mod type /var/folders/28/hhwsccr90x7_bwdl4dyl292m0000gn/T/haskell-ghc-mod11529-2337-ugp709.hs 31 3/Users/LiuMS/GitHub/BBQ/dist/setup-config: hGetContents: invalid argument (invalid byte sequence)

I am trying to use haskell-ghc-mod but haven't made any progress. Initially, whenever I tried to check an identifier's type, an error of "This socket is closed." was thrown. Later, I disabled "Enable Ghc Modi", the following problem appeared. Besides, whenever I save a file, the same error is thrown. (Considering the "check on save" I think this is reasonable).

I haven't used ghc-mod with any other ide/editors yet. It was installed through cabal and is indeed the latest version.

spawn error

getting this error msg when I open a haskell src file:

'ghc-modi' could not be spawned. Is it installed and on your path? If so please open an issue on the package spawning the process.

ghc-modi is installed and is in the current path. I can make this work by explicitly putting the path in the pkg settings within atom

spawn failure

Hello, I'm brand new here and, for me, using haskell-ghc-mod has never worked before because of this error:

Haskell-ghc-mod: C:\Users\Kieran\Appdata\Roaming\cabal\bin\ghc-mod.exe -d Playfair failed with error message Error: spawn C:\Users\Kieran\Appdata\Roaming\cabal\bin\ghc-mod.exe ENOENT

I'm on Atom version 1.0.0 and haskell-ghc-mod version 0.8.2 on Windows 8.1.

Type popups take several seconds to appear when ghc-modi is enabled

I am running:
Atom 1.0.2
haskell-ghc-mod 0.8.3
ide-haskell 0.6.2
ghc-mod version 5.2.1.2 compiled by GHC 7.8.4
GHC 7.8.4
Ubuntu 14.04

When ghc-modi is enabled in the haskell-ghc-mod Atom settings, it takes several seconds for the type to popup after hovering over some text. During this time the hourglass appears in the Haskell IDE panel. When the type finally appears, the hourglass turns back into a check-mark. Disabling ghc-modi fixes this; type popups appear promptly with the hourglass appearing for less than a second.

ghc-mod-master support

Getting some weird behavior with this plugin. Autocomplete Haskell is working fine, however ide-haskell is not highlighting the errors shown in the errors panel.

Controlling warnings shown

Nice module!

When I use ghc-mod from emacs, I run with this setting in my init.el:

(defvar ghc-ghc-options '("-fno-warn-name-shadowing") "*GHC options")

which disable the name shadowing warnings, which I really don't like.

How can I do this with the atom editors haskell-ghc-mod package?

Uncaught TypeError: Cannot read property 'getPath' for undefined

Affect version 0.8.6 . This may be related to #31

Reproduce:

Main Menu -> View -> Toggle Tree View make sure the left treeview is visible
remove any project folder in the left treeview
Main Menu -> Atom -> Preferences , now in the left treeview there will be an empty node named 'config'
open any .hs file
move mouse over a method or a variable , e.g. putStrLn, haskell-ghc-mod will show its type
right click on 'config' node in the left treeview and select 'remove project folder'
repeat 5 will cause an error 'Uncaught TypeError: Cannot read property 'getPath' of undefined'

Failed to spawn command ghc-mod

The latest update (not 100% sure about that) seems to have broken something.
It works for cabal projects, but when I open a single Haskell file I get the error.

Not really sure what other info I can provide.
I'm running Windows 8. Both Atom and all the ide-haskell packages are at their current latest versions.

This is the exception in the dev tools

Uncaught BufferedProcessError: Failed to spawn command `ghc-mod`. Make sure `ghc-mod` is installed and on your PATH

openFile: does not exist (No such file or directory)

I get endless stack traces of:

Haskell-ghc-mod: /Users/ptrckbrwn/.local/bin/ghc-mod check /Users/ptrckbrwn/git/github.com/ptrckbrwn/weblog/site.hs failed with error code 1
/Applications/ghc-7.8.4.app/Contents/lib/ghc-7.8.4/settings: openFile: does not exist (No such file or directory)

It's absolutely correct, I do not have ghc installed at /Applications/ghc-7.8.4.app. Is atom-haskell/hakell-ghc-mod compatible with ghc installed in other locations?

For example:

$ which ghc-mod
/Users/ptrckbrwn/.local/bin/ghc-mod

Not Auto-completing Haskell properly

Hi,

I have installed

$apm install language-haskell haskell-ghc-mod ide-haskell autocomplete-haskell

but, when i type import System. it is not auto-completing whole path. In Console, i am getting an error like :

"haskell-ghc-mod debug: System. moduleName mismatch: undefined != System."

i have set haskell environmnet variables in PATH. I have set ghc-mod and ghc-modi as
C:\Users\AppData\Roaming\cabal\bin

Let me know is there any configuration i missed to setup.

Thanks,
Senthil.

Does not work with ghc-mod 5.3.0.0

I have ghc-mod 5.3.0.0 on OS X. I get errors on launch:

ghc-mod failed to launch it is probably missing or misconfigured
failed to spawn command ghc-mod. Make sure ghc-mod is installed and on your PATH

ghc-mod runs perfectly fine when started from Terminal.app, it is installed by cabal, and is on path.
I know that it is specifically stated that ghc-mod 5.2.x is supported, but I still hope that this can be fixed. I cannot downgrade because it seem to necessitate a downgrade of ghc itself.

Thank You!

retrieval of the cabal configuration flags failed

Hello, I get the following error when I start up Atom:

ghc-mod spawn errors

Hello, good people.

Atom fails to spawn ghc-mod for me.

Error message:

/Users/rahulgomaphulore/Downloads/Atom.app/Contents/Resources/app.asar/src/buffered-process.js:260 Uncaught BufferedProcessError: Failed to spawn command `ghc-mod`. Make sure `ghc-mod` is installed and on your PATH

I am on OS X, but starting Atom from console.

Here's my ~/.atom/config.cson:

"*":
  "exception-reporting":
    userId: "526c136c-f715-ee5d-1def-7846da50cf76"
  welcome:

  ghcModiPath: "/Users/rahulgomaphulore/.cabal/bin/ghc-modi"
  additionalPathDirectories: "/Users/rahulgomaphulore/.cabal/bin/"

Here's a relevant chunk from my ~/.zshrc:

alias ghc-mod="~/.cabal/bin/ghc-mod"
alias ghc-modi="~/.cabal/bin/ghc-modi"
export ghcModPath="~/.cabal/bin/ghc-mod"
export ghcModiPath="~/.cabal/bin/ghc-modi"

As you can see, I am putting these settings pretty much everywhere, but nothing makes it work. :(

Path errors with OSX 10.10.3

On startup I'm getting the error:

Failed to spawn command /Users/dkoontz/Library/Haskell/bin/ghc-mod. Make sure /Users/dkoontz/Library/Haskell/bin/ghc-mod is installed and on your PATH

I have configured path in the settings for haskell-ghc-mod

"haskell-ghc-mod":
    additionalPathDirectories: [
      "/usr/bin/ghc"
    ]
    ghcModPath: "/Users/dkoontz/Library/Haskell/bin/ghc-mod"
    ghcModiPath: "/Users/dkoontz/Library/Haskell/bin/ghc-modi"

If I open my terminal and run /Users/dkoontz/Library/Haskell/bin/ghc-mod version I can confirm that I get ghc-mod version 5.2.1.2 compiled by GHC 7.8.3

When I hover over an identifier in a .hs file I get a second error

'/Users/dkoontz/Library/Haskell/bin/ghc-modi' could not be spawned. Is it installed and on your path? If so please open an issue on the package spawning the process.

I'm fairly stumped by what could be happening here. I've tried opening Atom from the command line, I've tried putting an explicit path in init.coffee as some other posts on this topic have suggested

process.env.PATH = ["/usr/bin",
                    "/usr/local/bin",
                    "/Users/dkoontz/Library/Haskell/bin",
                    process.env.PATH
                    ].join(":")

but that seems to have no effect.

Uncaught Error: write EPIPE

Yesterday it worked. Today I updated the ide-haskell and haskell-ghc-mod plugins.

Step to reproduce:
Simply reopening Atom with some haskell files open. Or simply opening a haskell file.

Together with the uncaught error message I also get the message: "'ghc-modi' could not be spawned. Is it installed and on your path? If so please open an issue on the package spawning the process."
I checked and ghc-modi is in my path.

Heads up: ghc-mod(i) must be run in project root directory

Hey,

This might be a breaking change depending on how you handle this now. You need to call ghc-mod root to get the project root directory, and start any other commands in that directory. We unfortunately have to push this to the frontend side because we can't just fork() on windows to work around it.

[Readme] Wrong links to services descriptions

The two links at the bottom of the readme (see picture below) give 404 error

Error crash

Haskell-ghc-mod: ghc-modi crashed on type with message 9 11 9 34 "WidgetT App IO (Route App -> [(Text, Text)] -> Text)"

No idea why

Typo in code?

Hi, I was just reading the code to understand how to write an hdevtools backend. Shouldn't this line:

https://github.com/atom-haskell/haskell-ghc-mod/blob/master/lib/haskell-ghc-mod.coffee#L41

say

unless atom.config.get('haskell-ghc-mod.suppressStartupWarning')

that is gch ====> ghc ?

Thanks!

Spurious `Could not find module`

Open this project. And modify P.hs on line 37 for example to introduce an error

                   , nulle

If I press CTRL+s again I get

Module ‘Data.List’ does not export ‘nulle’

as expected. If I fix the bug and save again, I get 9 errors (the same as before) and saving one more time removes all errors.

haskell-ghc-mod doesn't support local GHC using Stack

I'm creating a project using Stack that uses a different GHC version from $(which ghc). This causes

Haskell-ghc-mod: ~/.cabal/bin/ghc-mod check ~/project/File.hs failed with error code 1
cabal: At least the following dependencies are missing:
base >=4.7 && <5
ghc-mod: readProcess: cabal "configure" "--with-ghc=ghc" (exit 1): failed

because my local GHC doesn't support base >=4.7 && <5 but the one I'm stack building with does. Is there a way to configure haskell-ghc-mod to recognise and use GHCs on stack path when possible?
