ppx_blob

This is an OCaml PPX to include a binary blob from a file as a string. Writing [%blob "filename"] will replace the string with the contents of the file at compile time. This allows the inclusion of arbitrary, possibly compressed, data, without the need to respect OCaml's lexical conventions.

The filename can be relative to either the source file where [%blob] appears, or relative to the current working directory. If both files exist, the former takes precedence.

Integration with build systems

Dune

Add (preprocessor_deps (file path/to/file)) to your library or executable stanza. See test/dune for an example. This will make sure the file is copied to the build directory and therefore visible to ppx_blob.

Development

Requirements:

Run make and make test.
