I decided I needed a random colorscheme selector for those moments when you want to change things up but don’t want to make a specific choice. LazyVim already has uC for selecting a colorscheme, but it can be too mentally taxing as it requires you to manually select one. This script simply switches to a random one.

RandomColorScheme returns the name of a random colorscheme after searching through all available paths. SetRandomColorScheme sets the colorscheme to that choice. The keybinding is mapped to uR.

function RandomColorScheme()
  local color_schemes = vim.fn.globpath(vim.o.rtp, "colors/*.vim", false, true)
  for i, fullpath in ipairs(color_schemes) do
    color_schemes[i] = fullpath:match(".*/(.*).vim$")
  end

  -- Generate a random index
  local index = math.random(#color_schemes)

  local random_color_scheme = color_schemes[index]

  vim.notify("Random Color Scheme: " .. random_color_scheme)
  -- Select a random color scheme
  return random_color_scheme
end

function SetRandomColorScheme()
  vim.cmd("colorscheme " .. RandomColorScheme())
end

vim.api.nvim_set_keymap("n", "uR", ":lua SetRandomColorScheme()", { noremap = true, silent = true })

I believe in the value of reducing friction when taking notes. Today, I added a function to my Neovim configuration to create a timestamped file and open it for editing.

function CreateTimestampedFile()
  local zkdir = os.getenv("HOME") .. "/github.com/iesahin/garden/zk/"
  local timestamp = os.date("%Y%m%d%H%M%S")
  local filename = zkdir .. "/" .. timestamp .. ".md"
  vim.cmd("edit " .. filename)
end

vim.api.nvim_set_keymap("n", "F", ":lua CreateTimestampedFile()", { noremap = true, silent = true })

Now, I can just hit F (which is F in my setup) and immediately start adding a note to my zettelkasten.

I noticed it’s not possible to unmap the F1 key in Neovim using vim.api.nvim_del_keymap if it’s not already registered. Instead, you can simply override it with something like:

vim.keymap.set({ "n" }, "", ":Telescope buffers", { noremap = true, desc = "Find buffer" })

TIL 11: Unhide Markdown Code Block Types in LazyVim

Emre Şahin — 2024-02-26T10:22:29+00:00

To unhide Markdown code block types in LazyVim, you can set the conceallevel to 0.

Add the following to your configuration:

vim.opt.conceallevel = 0
