Error reading ShaDa

Resolution of Error while reading ShaDa file: there is an item at position …

Find all ShaDa related directories and files

find ~ -iname '*shada*'

Example list of folders returned by the find command above

/home/chris/.local/state/lvim/shada/
/home/chris/.local/state/nvim/shada/
/home/chris/.local/share/nvim/shada/
/home/chris/.cache/lvim/

Delete all shada files in these directories.

rm -rf ~/.local/state/lvim/shada
rm -rf ~/.local/state/nvim/shada
rm -rf ~/.local/share/nvim/shada
rm -rf ~/.cache/lvim

Swap files

Delete all swap files

rm -rf ~/.local/state/nvim/swap/*

Command line args

Mimics a fresh install of Nvim. “Factory defaults”, skip user config, plugins and shada

nvim --clean

Cause Nvim to look for configuration files in ~/.config/nvimfoo instead of ~/.config/nvim. Useful for experimenting with multiple Neovim configurations on the same system. See here for a potentially better strategy on Linux, using cgroups namespaces.

NVIM_APPNAME=nvimfoo nvim

Notes

  • Configuration ~/.config/lvim/config.lua
  • On my system, plugins directories are in ~/.local/share/lunarvim/site/pack/lazy/opt
  • To turn off ShellCheck warnings in .env files, place at the top # shellcheck disable=SC2034

Keybindings

Toggle spelling on/off with a function:

lvim.keys.normal_mode["<leader>sp"] = function()
    if (true == vim.opt.spell:get()) then
        vim.opt.spell = false
        print("spell = false")
    else
        vim.opt.spell = true
        vim.opt.spelllang = "en_gb"
        print("spell = true")
    end
end

Resize splits with number keys:

lvim.keys.normal_mode["<A-8>"] = ":resize -1<CR>"
lvim.keys.normal_mode["<A-9>"] = ":resize +1<CR>"
lvim.keys.normal_mode["<A-7>"] = ":vertical resize -1<CR>"
lvim.keys.normal_mode["<A-0>"] = ":vertical resize +1<CR>"
