als

https://github.com/AdaCore/ada_language_server

Installation instructions can be found here.

Can be configured by passing a "settings" object to als.setup{}:

require('lspconfig').als.setup{
    settings = {
      ada = {
        projectFile = "project.gpr";
        scenarioVariables = { ... };
      }
    }
}

require'lspconfig'.als.setup{}

  Commands:
  
  Default Values:
    cmd = { "ada_language_server" }
    filetypes = { "ada" }
    root_dir = util.root_pattern("Makefile", ".git")

angularls

https://github.com/angular/vscode-ng-language-service

angular-language-server can be installed via npm npm install -g @angular/language-server.

Note, that if you override the default cmd, you must also update on_new_config to set new_config.cmd during startup.

local project_library_path = "/path/to/project/lib"
local cmd = {"ngserver", "--stdio", "--tsProbeLocations", project_library_path , "--ngProbeLocations", project_library_path}

require'lspconfig'.angularls.setup{
  cmd = cmd,
  on_new_config = function(new_config,new_root_dir)
    new_config.cmd = cmd
  end,
}

require'lspconfig'.angularls.setup{}

  Commands:
  
  Default Values:
    cmd = { "ngserver", "--stdio", "--tsProbeLocations", "", "--ngProbeLocations", "" }

fsautocomplete

https://github.com/fsharp/FsAutoComplete

Language Server for F# provded by FsAutoComplete (FSAC).

Download a release of FsAutoComplete from here. Instructions to compile from source are found on the main repository.

FsAutoComplete requires the dotnet-sdk to be installed.

You may also need to configure the filetype as Vim defaults to Forth for *.fs files:

autocmd BufNewFile,BufRead *.fs,*.fsx,*.fsi set filetype=fsharp

This is automatically done by plugins such as vim-polyglot, PhilT/vim-fsharp or fsharp/vim-fsharp.

By default, this config doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of your unzipped and compiled fsautocomplete.dll.

require'lspconfig'.fsautocomplete.setup{
  cmd = {'dotnet', 'path/to/fsautocomplete.dll', '--background-service-enabled'}
}

require'lspconfig'.fsautocomplete.setup{}

  Commands:
  
  Default Values:
    filetypes = { "fsharp" }
    init_options = {
      AutomaticWorkspaceInit = true
    }
    root_dir = function(startpath)

If you have installed groovy language server, you can set the cmd custom path as follow:

require'lspconfig'.groovyls.setup{
    -- Unix
    cmd = { "java", "-jar", "path/to/groovyls/groovy-language-server-all.jar" },
    ...
}

require'lspconfig'.groovyls.setup{}

haxe_language_server

https://github.com/vshaxe/haxe-language-server

This will create bin/server.js. Note that the server requires Haxe 3.4.0 or higher.

After building the language server, set the cmd setting in your setup function:

lspconfig.haxe_language_server.setup({
  cmd = {"node", "path/to/bin/server.js"},
})

julials

https://github.com/julia-vscode/julia-vscode

LanguageServer.jl can be installed with julia and Pkg:

julia -e 'using Pkg; Pkg.add("LanguageServer"); Pkg.add("SymbolServer")'

The default config lazily evaluates the location of the julia language server from the your global julia packages. This adds a small overhead on first opening of a julia file. To avoid this overhead, replace server_path in on_new_config with a hard-coded path to the server.

require'lspconfig'.julials.setup{
    on_new_config = function(new_config,new_root_dir)
      server_path = "/path/to/directory/containing/LanguageServer.jl/src"
      cmd = {
        "julia",
        "--project="..server_path,

Omnisharp requires the dotnet-sdk to be installed.

By default, omnisharp-roslyn doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You must add the following to your init.vim or init.lua to set cmd to the absolute path ($HOME and ~ are not expanded) of the unzipped run script or binary.

local pid = vim.fn.getpid()
-- On linux/darwin if using a release build, otherwise under scripts/OmniSharp(.Core)(.cmd)
local omnisharp_bin = "/path/to/omnisharp-repo/run"
-- on Windows
-- local omnisharp_bin = "/path/to/omnisharp/OmniSharp.exe"
require'lspconfig'.omnisharp.setup{
    cmd = { omnisharp_bin, "--languageserver" , "--hostPID", tostring(pid) };
    ...
}

Note, if you download the executable for darwin you will need to strip the quarantine label to run:

rescriptls

https://github.com/rescript-lang/rescript-vscode

ReScript language server

By default, rescriptls doesn't have a cmd set. This is because nvim-lspconfig does not make assumptions about your path. You have to install the language server manually.

You can use the bundled language server inside the vim-rescript repo.

Clone the vim-rescript repo and point cmd to server.js inside server/out directory:

cmd = {'node', '<path_to_repo>/server/out/server.js', '--stdio'}

If you have vim-rescript installed you can also use that installation. for example if you're using packer.nvim you can set cmd to something like this:

cmd = {
  'node',
  '/home/username/.local/share/nvim/site/pack/packer/start/vim-rescript/server/out/server.js',
  '--stdio'
}

Another option is to use vscode extension release. Take a look at here for instructions.

require'lspconfig'.rescriptls.setup{}

  Commands:
  
  Default Values:
    cmd = {}
    filetypes = { "rescript" }
    root_dir = function(startpath)
        return M.search_ancestors(startpath, matcher)
      end
    settings = {}
