Description

It just takes a simple {range = true}. And it allows us to utilize commands from the :Legendary panel that run on a selection.

This should absolutely be doable, and not that difficult to implement. Basically:

• Add opts.range = true to the :Legendary command in lua/legendary/api/cmds.lua
• In the function that implements the command, grab the current range, if one was passed
• Pass the range down to the UI via the opts parameter
  • instead of just l.find(), do l.find({ range = the_range_we_got })
  • Update the M.select(opts) function in lua/legendary/ui/init.lua to accept an opts.range option
  • Pass opts.range into the Executor context builder like so: local context = Executor.build_context(nil, opts.range)
  • Update the M.build_context(buf) function in lua/legendary/api/executor.lua like the following:

---Build a context object containing information about the editor
---state *before* triggering the finder so that it can be
---restored before executing the item.
---@param buf number buffer ID to build context for, used only for testing
---@overload fun():LegendaryEditorContext
---@overload fun(buf:number):LegendaryEditorContext
---@return table
function M.build_context(buf, range)
  buf = buf or vim.api.nvim_get_current_buf()
  return {
    buf = buf,
    buftype = vim.api.nvim_buf_get_option(buf, 'buftype') or '',
    filetype = vim.api.nvim_buf_get_option(buf, 'filetype') or '',
    mode = vim.fn.mode(),
    cursor_pos = vim.api.nvim_win_get_cursor(vim.api.nvim_get_current_win()),
    marks = range or Toolbox.get_marks(),
  }
end

Well I think you can already filter out commands specific to the visual/selection mode when activate Legendary:

   {
      mode = { "n", "v", "i" }, "<C-S-P>" 
      , function()
         require("legendary")
         .find( { filters = { filters.current_mode() } })
      end ,
      description = "Window: open command palette (Legendary plugin)"
   }

I didn't use it extensively though.

Not from cmdline. :<‘>’Legendary doesn’t currently work.

Oh yeah, it's for user cmd... overlooked that.
