Neovim

Building Neovim

  1. Clone Neovim repo https://github.com/neovim/neovim.git
  2. Make with make CMAKE_BUILD_TYPE=Release install
  3. To change install directory add CMAKE_INSTALL_PREFIX=$HOME/Example/Dir to command above
  4. Try rm -rf build if build fails after pulling from master
  5. Even better, do make distclean and make CMAKE_BUILD_TYPE=Release

Troubleshooting

unknown terminal type = missing terminfo

If we got error unknown terminal type while setting up the TERM value, it's because we're missing terminfo information for that particular TERM on current machine. To solve this, we need another machine that have that terminfo. Here's how we can get that info for current machine.

  1. Export from donor machine infocmp -x _<TERM_NAME>_ > _<FILENAME>_
  2. Transfer to current machine.
  3. Import with tic -x _<FILENAME>_
  4. Set our TERM env with new <TERM_NAME>

Error installing Neovim HEAD with homebrew

If we got the following error

Solution

This should be fixed in Homebrew for now. You need to do brew unlink libvterm (or brew uninstall --force libvterm if you don't otherwise need it) if you have Homebrew installed into /usr/local. If that still doesn't work, do brew update first.

Tips

  1. Spelling
  • ]s or [s to jump to misspelled words.
  • zg to add word under cursor to external dictionary.
  • z= to get suggestions for misspelled word under cursor.
  1. Neovim <3 Lua
  • To access vim function from lua, prefix the function with vim.fn. Ex. vim.fn.fnameescape
  • To access vim variable from lua, prefix the function with vim.v. Ex. vim.v.oldfiles
  • To access vim global settings from lua, prefix the function with vim.g. Ex. vim.g.loaded_zip
  • To access vim options from lua, prefix the function with vim.opt. Ex. vim.opt.clipboard

Wezterm

Wezterm not detecting foreground process

Regarding this issue with Wezterm. It's actually zplug fault for not clearing it's job lock file in ~/.zplug/log/job.lock, this maybe happened when we interrupt zplug process forcefully.

This solution is found while searching why zsh can't send process to background with CTRL+z and looking at Wezterm REPL/debug message (SHIFT+CTRL+L), no other foreground process got detected.

So if you use zplug and have the same problem, find the ~/.zplug/log/job.lock and delete it.

Glitch over remote connections

  • First happens in mosh
  • Only recently
  • Seen in neovim, tmux, nnn
  • Also happens over SSH
  • Still happens in Zellij
  • Also happens with wezterm over mosh
  • SSH with Tmux on wezterm ok currently
