JetBrains IntelliJ IDEA Support

[snoweuph]

We'll need to decide whether we wanna package unfree stuff. Also in the future we might need some custom LSP commands for log in

CI fails due to it being a UNFREE package.

[snoweuph]

found the fix. its 2 part.

1. If you use maven or gradle, have it in your path (should be via a devshell provided and not shipped with nvf). if it detects maven or gradle, but those are not available it can't even resolve String
2. Define JDK in the LSP init options

[sand4rt]

i've tried that, but without success. i still cant do a go to definition on imported lib

[snoweuph]

FYI I updated inside this branch earlier. as for why it doesn't work, for you I don't know. did you look at your lsp.log file yet?

[sand4rt]

My flake input is:

nvf.url = "github:NotAShelf/nvf/3d54267724fe2da0abbbc7901875527b1e02120b";
nvf.inputs.nixpkgs.follows = "nixpkgs";

this is the nix config:

let
  intellij-server =
    pkgs.callPackage
      "${inputs.nvf}/flake/pkgs/by-name/intellij-server/package.nix"
      { };
in
{
  vim.lsp.enable = true;

  vim.languages.java = {
    enable = true;
    lsp.enable = false;
    extensions = {
      maven-nvim.enable = true;
      gradle-nvim.enable = true;
    };
  };

  vim.languages.kotlin = {
    enable = true;
    lsp.enable = false;
  };

  vim.lsp.presets.intellij-server.enable = true;
  vim.lsp.servers.intellij-server = {
    filetypes = [
      "java"
      "kotlin"
    ];

    cmd = lib.mkForce [
      (lib.getExe intellij-server)
      "--stdio"
      "--data-sharing=none"
      "--region=not_set"
    ];

    init_options.eulaHash = lib.mkForce (
      lib.generators.mkLuaInline ''
        (function()
          local file = assert(io.open("${intellij-server}/EULA.txt", "rb"))
          local hash = vim.fn.sha256(file:read("*a"))
          file:close()
          return hash:sub(1, 16)
        end)()
      ''
    );
  };
}

remove nvf.inputs.nixpkgs.follows = "nixpkgs"; plz. we dont support overriding nixpkgs for nvf, we always just test with the version we bundle

[snoweuph]

also youre overriding the cmd args and co for the lsp, why?

just test with

{
  vim.languages.java = {
    enable = true;
    treesitter.enable = true;
    lsp = {
      enable = true;
      servers = ["intellij-server"];
    };
    dap = {
      enable = true;
      debugger = ["intellij-server"];
    };
    extensions = {
      maven-nvim.enable = true;
      gradle-nvim.enable = true;
    };
  };
}

[sand4rt]

thanks for the tips, i`ve tried it with your sample, but got the same result. im using a gradle btw.

[snoweuph]

huh, im using maven. gradle is shit after all, doesnt even have the concept of licenses

[snoweuph]

Got the DAP hacked together to work locally

gonna clean this up and add to this MR later :3
gonna need some rest now

[snoweuph]

will only apply after the MR is merged.

[snoweuph]

new version theoreticlly has the test runner shiped and also now has lombok support. for now just updated the urls and hashes, so no custom wiring for the test runne yet
