ocaml.nvim
Tools for working with OCaml. Status is very work in progress and likely to break. Use at your own risk (but feel free to file issues)
Just some utilties for working with ppx_rapper.
If you're not using OCaml (you should be) then this plugin is worthless to you.
Installation
Plug 'tjdevries/ocaml.nvim', {'do': ':lua require("ocaml").update()'}
And then, you'll probably need to do this before you load nvim-treesitter
(if you want to use ensure_installed
, but I do my best to make this not required)
require('ocaml').setup()
NOTE: you'll probably need to do this for your lspconfig (if you're using it)
ocamllsp = {
get_language_id = function(_, ftype)
return ftype
end,
},
Feature: Highlighting
- Automatically highlight code from
ppx_wraper
:
let create_query =
[%rapper
get_one
{|
INSERT INTO resources (name)
VALUES (%string{name})
RETURNING @int{id}
|}]
;;
You can customize the colors by doing something like:
hi! link @rapper_argument @parameter
hi! link @rapper_return @type
- Automatically highlight code from
%graphql
:
module SomeGraphql = [%graphql
{| mutation deposit($account: String, $amount: UInt64) {
changeBalance(account: $account) {
payment {
id
}
}
} |}
];
You just need to have graphql
grammar installed.
Feature: Easily update types in .ml
/.mli
files
You can map a function to easily update the corresponding type in your .ml
or .mli
files, by doing:
-- Use <leader>out to update the type
vim.keymap.set("n", "<leader>out", require('ocaml.actions').update_interface_type, { desc = "[O]caml [U]pdate [T]ype" })
