[mini.tabline] Update display name when terminal buffer issues OSC 0 or 2

[badosu]

A simple configuration to detect when OSC 0 (icon + title) or OSC 2 (title) is issued by the terminal buffer and updating the display name.

vim.api.nvim_create_autocmd('TermRequest', {
  desc = 'Redraw tabline when OSC0 or OSC2 is issued (set title)',
  callback = function(ev)
    if ev.data.sequence:find("^\27%][02];") then
      vim.cmd.redrawtabline()
    end
  end,
})

require("mini.tabline").setup({
  format = function(buf_id, label)
    local term_title = vim.b[buf_id].term_title
    if term_title and term_title ~= "" then
      label = term_title
    end

    return MiniTabline.default_format(buf_id, label)
  end,
})

As an interesting note, for some reason this doesn't work (it always returns) unless I uncomment the notify, any ideas?

-- vim.notify(vim.inspect(title))
if not title or title == vim.b[args.buf].term_title then
  return
end

Not sure about why commenting out vim.notify makes it work, but vim.b.term_title is already automatically set (at least on Neovim 0.12.3).

So instead of autocommand for setting vim.b.term_title, it can be for just redrawing tabline:

vim.api.nvim_create_autocmd('TermRequest', {
  desc = 'Redraw when OSC0 or OSC2 is issued (set title)',
  callback = function(args)
    local title = args.data.sequence:match('^\27%][02];(.*)$')
    if title ~= nil then vim.cmd.redrawtabline() end
  end,
})

That explains it 😅.

That works, much simpler! Thanks :-).

That's nice! Thanks for sharing! Somehow I missed the b:term_title (it is even documented). I'll take it for a spin and see if this something fit for 'mini.tabline'.
