How to get build / set stack to include resource files (configs, images, etc.)

After putting the stack as a step to start writing non-trivial haskell programs (more than one file), I ran into the problem of not knowing how to get the stack to recognize .ini files, etc. It doesn't seem to fit in the .cabal or stack.yaml files anywhere.

To clarify: after starting the build / installing the stack, the folder with the generated .exe file has no resources, and therefore, of course, the program crashes with a bunch of I / O errors (file not found).

There are two options. I assume you are looking for data files . To do this, you essentially:

  • Add the appropriate files to the box data-files

    in the file .cabal

    so they are installed when the package is created
  • Add the module Paths_package_name

    to yours other-modules

    in your .cabal

    file (replace package_name

    with your package name)
  • Import the module Paths_*

    if needed
  • Use the generated function getDataFileName :: FilePath -> IO FilePath

    to get the absolute path to the data file you want.


An alternative is to embed the content of the data file inside the executable itself using Template Haskell, for example with the file-embed package .
