rouge atom://config node leading to spawn ghc-mod ENOENT

[cblp]

rootPath may be a URL, for example, atom://config.

debug info: haskell-ghc-mod debug: PATH = atom://config/.cabal-sandbox/bin:/usr/bin:/home/cblp/b…n:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

[lierdakil]

I've encountered this, but could not track it down If you could provide a test case, that would be great.

[lierdakil]

Alternatively, if you can reproduce this, update to 0.8.2, enable "Debug" in haskell-ghc-mod options, and post dev. console output here.

[wridgers]

I have this problem, using 0.8.3. I am on Windows.

Here's the output from dev. console:

How else can I help?

[lierdakil]

@wridgers, thanks, but according to provided output, you seem to have a different problem, reported in #32. I think this should be fixed in 0.8.4.

[wridgers]

@lierdakil You're absolutely right, my apologies! Thanks.

[lierdakil]

@Centaur, sorry, traces are completely useless here. Not sure why, but they don't show actual trace. Can you actually reproduce this, or is it a random occurrence? Could you explain how to reproduce this, if possible?

[Centaur]

Every time opening a haskell source file, two red error popups at top-right corner says: "Haskell-ghc-mod: /Users/user/.cabal/bin/ghc-mod -d Main failed with error message Error: spawn /Users/user/.cabal/bin/ghc-mod ENOENT" and "Haskell-ghc-mod: /Users/user/.cabal/bin/ghc-mod -d Prelude failed with error message Error: spawn /Users/user/.cabal/bin/ghc-mod ENOENT" . Main is the module name defined in my source code.

/Users/user/.cabal/bin/ghc-mod does exist. I can run it in the shell.

[lierdakil]

How do you open those files?

[Centaur]

Atom Main Menu -> File -> Open , or dragndrop using mouse, what ever.

[lierdakil]

Makes no sense to me. Probably a quirk in Atom. I'll just try monkey-patching it then.

[lierdakil]

Please check if v0.8.6 fixes this issue.

[Centaur]

Ok. I think I have found out how to reproduce this in 0.8.5

1. Atom Main Menu -> View -> Toggle TreeView. make sure left treeview is visible
2. remove any project folder in the left treeview.
3. Atom Main Menu -> Atom -> Preferences then in the left treeview there is only an empty root node named 'config'. now open any .hs file will trigger the error.
4. Now right click on the 'config' node in the left treeview and select "remove project folder" then the error disappears.

This is really weird.

[lierdakil]

Thanks. This happens on Linux as well. Funny thing is, if you open preferences with hotkey (ctrl+, on Linux/Win -- not sure what OS X hotkey is), this rouge 'config' node doesn't show up. Doesn't break 0.8.6 for me, thankfully. Could you please confirm this?

Anyway, I think rouge 'config' node is a bug, and is worth reporting upstream. Would you prefer me to do it, or would you rather do it yourself?

[Centaur]

I think it's better you submit the bug report because you know the details much better than me. Thank you very much. 0.8.6 fix this immediate error but I have encountered another exception. I will file a separate issue for that.

[3noch]

I'm getting this on Windows. I'm using stack and GHC 7.10.2 with the latest release of ghc-mod (built with GHC 7.10.2). I've confirmed that ghc-mod check Build.hs works, but opening it in Atom produces a slew of errors like spawn ghc-mod ENOENT. Anything I can do to be helpful?

[3noch]

Could this be helpful for Windows? http://stackoverflow.com/questions/17516772/using-nodejss-spawn-causes-unknown-option-and-error-spawn-enoent-err

[dgpratt]

I'm also encountering this on Windows in basically the same configuration as @3noch. I determined that atom-haskell is launching ghc-mod like ghc-mod "legacy-interactive". I then inferred from the error messages in atom that it was sending a command to ghc-mod like browse -d Site.

I did likewise through a command prompt and this was the output:

Is that litany of warnings confusing atom-haskell, or is it likely I'm not seeing the actual issue in this process?

[lierdakil]

@3noch, @dpratt71, could we open new issue for this? Your case is unrelated to what was reported by OP.

[lierdakil]

Nevermind, I figured it out. v0.9.9 should work.

[3noch]

Woot! It's working! Thank you so much!

[oreqizer]

i've encountered this - happens if I create a .hs file in Atom.

if I open it with File > Open, everything works ok

[lierdakil]

@Oreqizer -- what you ran into is not much of an issue. It's not, in general, possible to check/lint/query a Haskell file that doesn't have a filename. I've added a couple checks to avoid unsightly error messages, but newly-created file won't work until you save it. Depending on your setup, you might also need to add it to your cabal file.

[oreqizer]

I just realized that it does not work, it just doesn't start at all - thus no error.

Now, this error is shown:

my ghc-mod is installed correctly, tho:

is it possible that it works from the terminal, but not in Atom?

[lierdakil]

@Oreqizer -- please see https://github.com/atom-haskell/haskell-ghc-mod#configuration. TL;DR -- unless ghc-mod, ghc etc are not in system PATH, additional setup is required, mostly amounting to telling Atom where to look for said executables.
