Goal

This project aims to provide a non intrusive Neovim configuration for Go development. The idea is that you can easily use this setup not having to touch your current Vim/Neovim configuration files.

Motivation

Go2one was created for someone who:

• wants to quickly try running Neovim with IDE features with modern technologies (LSP, Treesitter, DAP, etc) with zero configuration required.
• is curious about Neovim new features but wants to keep their current Vim/Neovim configuration files untouched.
• is curious about one specific plugin and wants to see it in action before spending time configuring it.

Features

• Quick docs, go to definition, go to implementation, find usage, diagnostics (native LSP)
• Git Integration (gitsigns + fugitive)
• Cool tree-sitter based themes (catppuccin, onedark)
• Code snippets (vim-vsnip)
• Auto completion (nvim-cmp)
• Fuzzy find about everything (telescope)
• Easy file context visualization (lualine + bufferline)
• Debugging (nvim-dap + nvim-dap-go)

and more..

Installation

Go2one provides two different installation methods:

Native install

Will use your current Neovim installation with isolated configuration files. This won't affect your existing Vim/Neovim setup.

This method will create two entries in your filesystem:

• /usr/local/bin/go2one: This a bash script that will be responsible to manage go2one configuration files and starting Neovim in a sandbox.
• $HOME/.config/go2one: This is the folder where all configuration and plugin files will be created.

Pre-reqs

• Neovim: 0.5.1
• Go: SDK for Go
• delve: for debugging Go projects
• gopls: LSP server for Go
• fzf: Fuzzy search of filesystem
• ripgrep: Live grep project file
• fd: Quickly find repos in the filesystem

To install go2one just run the command bellow:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/leoluz/go2one/main/scripts/install.sh)"

Once the installation is concluded just run the go2one command to start the sandboxed Neovim.

See go2one -h for additional commands about how to update or uninstall go2one.

Container based

Using this method, nothing will be installed in your computer. Neovim will run in a docker container with all dependencies installed and ready to use. The only requirement in this case is having Docker installed.

Note: Keep in mind that on MacOS or Windows, this method is going to have a lower filesystem performance if compared with the native installation. See this github issue for updates regarding this problem.

Pre-reqs

• Docker

Just run the following command in the folder having the files you want to edit:

docker run --rm -it -v$(PWD):/home/nvim/work leoluz/go2one:latest

Upgrading

nvim-0.7.0

Seems some previously compiled Treesitter parsers are incompatible with 0.7.0 and the following error might show up:

treesitter/highlighter: Error executing lua: /usr/share/nvim/runtime/lua/vim/treesitter/query.lua...

If this is the case run the following command in the terminal:

rm $HOME/.config/go2one/data/nvim/site/pack/packer/start/nvim-treesitter/parser/*

Then start nvim and run:

:TSInstall all
