Including text files to embed with Cabal

Question

I've got a library I'm building that includes a few very large strings using Template Haskell and file-embed.

I'm wondering, how do I ensure these files are included when I run Cabal dist?

The are all in a folder called core, but some are within subdirectories of core.

Answer 1

Cabal has an extra-source-files field precisely for these kinds of scenarios:

Extra-source-files: relative/path/to/my/embedded-file.txt

Quoting the Cabal User Guide :

extra-source-files : filename list

A list of additional files to be included in source distributions built with setup sdist .

As with data-files it can use a limited form of wildcards in file names.
