Neomake integration with bare files and STACK_YAML

[parsonsmatt]

Copied from #67 (thanks @tsoernes!):

When using STACK_YAML environment variable to specify a stack.yaml file, the neomake integration fails with following message:

Error detected while processing function <SNR>51_on_stdout[26]..<SNR>51_new_response[22]..intero#maker#write_update:
line    3:
E482: Can't open file /tmp/nvimWuC10t/3 for writing: no such file or directory

I don't use a STACK_YAML env var (echo $STACK_YAML doesn't print anything and I haven't set it myself), I assume stack just defaults to the global yaml file when run as a bare file.

That use case is working for me, oddly enough.

I'm not getting this issue on my other system using the exact same init.vim, editing same file on same operating system with same neovim version so I'm not getting any wiser. The systems are configured to be as identical as possible.

The weird thing about this is that we switched to using a tempfile instead of .stack-work specifically because of Stack scripts. Looking at the output of tempname() on the affected system could be interesting - I suspect the /tmp/nvimWuC10t directory doesn't exist.

My previous analysis of this issue was incorrect.

The error happens when the line

#!/usr/bin/env stack

is either added then :wq or removed then :wq.

In either case you won't get it the second time the file is opened then :wq (without editing anything) because in case 1 (line is present) intero won't start the second time around and in case 2 (line not present) intero seem to work correctly on bare files as @rdnetto mentioned.

When replicating these steps I also get this error on my other system.

It's for that reason that I think this issue is not Intero related. A while ago, I added this line to my vimrc: au! BufRead,BufEnter *.hs setlocal filetype=haskell This is more of a problem in the ftdetect files for haskell/conf than a problem with Intero. Maybe we should submit a bug report or a patch upstream, but I'm content merely adding this line to my vimrc.
