[mini.ai] How to move_cursor backward

[drowning-cat]

Note

Inspired by chrisgrieser/nvim-spider.

Let's define a textobject for selecting a subword:

local MiniAi = require("mini.ai")
MiniAi.setup({
  mappings = {
    -- Move forward
    goto_left = "g[",
    goto_right = "g]",
  },
  custom_textobjects = {
    e = {
      {
        "%f[%a]%l+%d*",
        "%f[%w]%d+",
        "%f[%u]%u%f[%A]%d*",
        "%f[%u]%u%l+%d*",
        "%f[%u]%u%u+%d*",

It could also be useful to jump backward between subwords:

vim.keymap.set("n", ",e", function() MiniAi.move_cursor("left", "a", "e", { n_times = vim.v.count1 }) end, { desc = "Next subword" })
vim.keymap.set("n", ",E", function() --[[ move backward ]], { desc = "Prev subword" })

|move_subword_next
2,e
move_subword_|next
,E
move_|subword_next
cae [1]
move|_next

This is already possible with opts.search_method='prev'. So something like this should work:

local make_ai_jump = function(side, tobj_id, search_method)
  return function() MiniAi.move_cursor(side, 'a', tobj_id, { n_times = vim.v.count1, search_method = search_method }) end
end
vim.keymap.set('n', ',e', make_ai_jump('left', 'e', 'cover_or_next'), { desc = 'Next subword' })
vim.keymap.set('n', ',E', make_ai_jump('left', 'e', 'prev'), { desc = 'Prev subword' })

Adjust search_method values to your liking (like 'cover_or_prev' instead of 'prev', etc.).

Thank you 😆
Too many letters - reading is hard.
