Getting Started

The plugin is tested against Neovim (v0.7.0) and the latest neovim nightly commit, so it is unknown if earlier versions work correctly.

Requirements

• Jdtls setup using either lsp-config or nvim-jdtls. (or anything that uses the built in neovim lsp)
• nvim-treesitter
• Plenary

Installation

The plugin can be installed just like any other neovim plugin manager.

You could install java-util.nvim using:

• main branch
• dev branch (Will have the latest features)
• Any release tag

Using packer.nvim

use({
  "tobias-z/java-util.nvim",
  branch = "main",
  -- or branch = "dev"
  -- or tag = "0.1.0"
  requires = {
    { "nvim-treesitter/nvim-treesitter" },
    { "nvim-lua/plenary.nvim" }
  }
})

Setup

To make java-util work correctly you must call the setup function.

require("java_util").setup({})

Usage

Functions can be executed through either user commands or calling lua functions.

Example using lua

local opts = {
  noremap = true,
  silent = true,
--  buffer = bufnr (if this is done during an lsp on_attach)
}

vim.keymap.set("n", "<leader>rr", require("java_util.lsp").rename, opts)

Example using vimscript

nnoremap <leader>rr <cmd>JavaUtil lsp_rename<cr>

        local has_luasnip, luasnip = pcall(require, "luasnip")
        if not has_luasnip then
          return string.format(
            [[
package %s;

public class %s {

            info.package,

            [[
package %s;

public class %s {

  $0
