Gemini proposed this:

git diff --word-diff=plain -- "*.md" | rg -o '\{\+(.*?)\+\}' | str replace -r '\{\+|\+\}' '' | str join " " | str words | length

What I ended up doing:

git diff --word-diff=plain -- "*.md" | rg -o '\{\+(.*?)\+\}' | str replace -a "{+" "" | str replace -a "+}" "" | str replace -a ' ' "\n" | lines | length

I notice LLMs tend to err on the side of complexity. I don’t know if this is due to their training to spit as many tokens as possible, but using regular expressions when a simple single replace may suffice is a good sign that they may be adding more complexity than necessary.

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", "<leader>F", ":lua CreateTimestampedFile()<CR>", { noremap = true, silent = true })

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

vim.keymap.set({ "n", "i" }, "<F2>", '<esc><esc>yy:r!<c-r>"')

I type a command, like ls, on a line and hit <F2>. That line is copied, executed, and the output is read into the buffer just below it.

I use it for all sorts of tasks, from listing open PRs with gh to fetching website text with w3m. It has significantly improved my workflow, allowing me to use the shell effectively within textual notebooks.

bind-key -n S-F12 split-window -h -c "#{pane_current_path}" "gt c"

I just hit Shift-F12, and it opens a new pane in the current directory and runs the command.
