False positive error using embedFile with relative path

[swsnr]

No, there isn't yet. This requires deeper changes to Flycheck, see flycheck/flycheck#813. It'll come, some day, but not any time soon. It's a larger and deeper change, it requires careful testing, and that takes time that I don't have currently.

I'm closing this issue, please subscribe to flycheck/flycheck#813 to keep track of this. Thank you for your feedback.

The Flycheck change seems to have happened, but this still doesn't work for me.

@XenoG Can you provide a reproducible test case?

[jprupp]

@sergv, clone this repository in Spacemacs with the haskell and syntax-checking layers and then open this file. You should see this error near embedFile:

   109  12 error           • Exception when trying to run compile-time code:
     config/config.yml: openBinaryFile: does not exist (No such file or directory)
   Code: embedFile "config/config.yml"
 • In the untyped splice: $(embedFile "config/config.yml") (haskell-stack-ghc)

[sergv]

@XenoG I have reproduced the problem and I think I know what's causing the issue. The issue with current directory was resolved and now ghc is being executed from the directory that contains stack.yaml file, which in this case in the root of the project. However, file path is specified relative to root of subproject, thus the does not exist error. However, I cannot think from the top of my head of any reasonable strategy to deal with this issue...

Great, if the working directory is that one where the stack.yaml file is, I know exactly what I can do to patch the problem in my code.
