using

(using <plugin> <version>)

Enable a dune language extension.

The language of configuration files read by Dune can be extended to support additional stanzas (e.g., menhir, coq.theory, mdx).

<plugin> is the name of the plugin that defines this stanza and <version> describes the configuration language’s version. Note that this version has nothing to do with the version of the associated tool or library. In particular, adding a using stanza will not result in a build dependency in the generated .opam file. See generate_opam_files.

Example:

(using mdx 0.3)
