What?

• Why don't you consider using Language Server Protocol ?

  Mainly because I want a strong integration in the IDE and I need a first class support of Windows.

• What versions does the plugin support at the moment?

  It should work with idea 15

• How is it different than ocaml language plugin?

  I wanted to have a plugin dedicated to reason and that's why I created one called reasonml, not ocaml. Then I realised that I still need ocaml support and that people are asking for it.

  I started this plugin by studying and copying parts of the ocaml plugin, but now the 2 projects are taking different orientations, technically.

  I am moving away from merlin and trying to use the most of Intellij structures.

  Now, they have incompatible implementations, and different goals.

Development

This project is heavily inspired by :

• custom language tutorial from intellij
• ocaml language plugin from sidharthkuruvila ( 👍 )
