VSCode

You can install the vscode extension to use the language server.

Neovim

First install mlogls globally with a package manager:

npm i -g mlogls

Then, you can have a simple setup using lspconfig.

local lspconfig = require("lspconfig")
local configs = require("lspconfig.configs")

vim.filetype.add {
  extension = {
    mlog = "mlog"
  }
}

configs.mlogls = {
  default_config = {
    cmd = { "mlogls", "--stdio" },
    filetypes = { "mlog" },
    single_file_support = true
  }
}

configs.mlogls.setup {}
