+# Neovim configuration for Go development using lazy.nvim and go.nvim
+
+* [YouTube Video](https://youtu.be/n5_WLgxwkU8)
+* [Blog post](https://mariocarrion.com/2024/05/20/neovim-migrating-to-lazy-and-go-nvim.html)
+
+## Requirements
+
+* Install a patched font, my favorite is [JetBrains patched font](https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/JetBrainsMono).
+
+If you're using [iTerm](https://www.iterm2.com/downloads.html), I recommend the following preferences:
+
+* General -> Working Directory -> Advanced Configuration -> Working Directory for New Tabs -> Reuse previous session's directory
+* Text -> Font -> JetBrainsMono Nerd Font
+* Text -> Font -> Use ligatures
+* Text -> Font -> Anti-aliased
+* Keys -> General -> Left Option key -> Esc+
+* Keys -> Key Mappings -> Presets -> Natural Text Editing
+
+## Install
+
+You can copy the content of this folder to your Neovim config path or create a
+symbolic link, to know your Neovim config path use the following command:
+
+```
+:echo stdpath("config")
+```
+
+[lazy.nvim](https://github.com/folke/lazy.nvim) is the plugin manager, use `:Lazy` to install all plugins.
+
+### Dependencies
+
+Make sure the following are installed:
+
+* Python 3: `brew install python`. Make sure is a recipe for python3.x, and then `pip3 install neovim`.
+* `fd` alternative to `find`: `brew install fd`. Used by "telescope" plugins.
+
+## Tricks
+
+* Beautify JSON buffer: `:%!jq`
+
+## Language Server Protocol Implementations
+
+* [Go: gopls](https://github.com/golang/tools/tree/master/gopls)
+```
+go install golang.org/x/tools/gopls@latest
+```
+
+* [Python](https://github.com/microsoft/pyright)
+
+```
+brew install pyright
+```
+
+* [Ruby](https://solargraph.org/)
+
+```
+gem install solargraph
+```
+
+* [PHP](https://github.com/phpactor/phpactor)
+
+```
+brew install php
+```
