Plugin development

• watch Developing a Neovim Docker Plugin from Scratch - YouTube which was recommended in Jonas Hietala: Customizing Neovim

Ctrl+w deletes the last word in insert mode

🫵 custom mapping

• inspect custom mappings with :map

copy current file path to system clipboard :let @+ = expand("%")

Help

• F1 - 🫵 fuzzy search through tags
• CTRL-] - go to tag
• CTRL-T - go back - tag stack
• Ctlr+O - go back - jump list
• :helpgrep - grep through all help pages
• :Helptags - fzf search through help tags

Search and replace

• Visual selected text

  • yank it
  • type in the :%s/<C-R>0/replace text/
  • Ctrl+R pastes a register
  • 0 is the yank register

• across the whole project

  • :grep <search term>
  • :cfdo %s/<search term>/<replace term>/g
  • (If you want to save the changes in all files) :cfdo update

LSP support

• I installed the nvim-lspconfig plugin to make the LSP server config eaiser https://github.com/neovim/nvim-lspconfig
• For TypeScript, it required me to install the language server with

  • npm install -g typescript typescript-language-server
    

• Other LS configs can be found here https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#tsserver
• Rename tweak: Neovim LSP rename like a boss (with normal mode keymaps)
• Neovim - Make LSP Workspace Symbols show only workspace symbols

Debugging

• mappings

  • :verbose map <key>
  • taken from Debugging Lua mappings/commands/autocommands

• General

  • open logs with :e $NVIM_LOG_FILE
  • set verbosity -V9 (e.g. vim -V9 file.txt)

• lua modules

  • I found where lua module is loaded from with :lua print(debug.getinfo(package.loaded["nvim-treesitter.configs"].attach_module, "S").source)
  • I found out that lazy.nvim changed the runtimepath with a slight delay. So my init script was able to import the module from the “default” runtimepath and shortly after lazy.nvim changed runtimpath but the pesky module has already been loaded.
  • The best way is to skip init file with nvim -u NONE and then inspect the :set runtimepath to see where the modules can come from

Formatting

• :noautocmd w will turn off the “format on save” for this single command

Fast search and replace

• cgn replaces the next search term, then you can press . to repeat

TODOs

• It happens to me quite often that I see some diagnostics
  • 
  • But I don’t know what plugin is adding them.
  • I need to find a way to diagnose the diagnostics 👹
• I sometimes see error in the command window:
  • 
  • I would like to be able to quickly copy it to the clipboard so I can search for solution on the web.
