Ecaml is a library for writing Emacs packages in OCaml. It uses Emacs
25 support for dynamic modules to load native OCaml code into Emacs.
Compile your plugin using (modes (native shared_object)) in the executable
stanza of your dune file. See example/dune.example
for an example.
Simply add (only_shared_object true) to the executables stanza in
your jbuild. For instance:
(executables
((names (my_plugin))
(libraries (ecaml))
(only_shared_object true)))Then build my_plugin.so with jenga. This has been tested in opam
using jane-build.
You need to use the -output-complete-obj option of ocamlopt to
produce a self-contained shared object file. For instance to build the
plugin in the example/ directory:
$ ocamlfind ocamlopt -linkpkg -package ecaml -thread -output-complete-obj \
-runtime-variant _pic -pp ppx-jane example_plugin.ml -o example_plugin.soAs of Emacs version 25, Emacs supports plugins. Here is the API:
