How to focus summary window on toggle?

[lawrence-laz]

I use lua require("neotest").summary.toggle() to open and close summary window, but the window does not get focused automatically. Any way I could get it to focus on open?

You can do this in your mapping callback

      neotest.summary.toggle()
      local win = vim.fn.bufwinid("Neotest Summary")
      if win > -1 then
        vim.api.nvim_set_current_win(win)
      end

Great, this is what I was looking for!

It works just as expected, but LSP is showing a warning on bufwinid call:

Any idea why this might happen?

Just incorrect type annotations from neodev.lua, perfectly safe to ignore

Actual summary toggle method expands the summary window till the nearest test, but with above snippet it always remains at the root of hierarchy.

Default behaviour:

          require("neotest").summary.toggle()
          vim.defer_fn(function()
            ---@diagnostic disable-next-line: param-type-mismatch
            local win = vim.fn.bufwinid("Neotest Summary")
            if win > -1 then
              vim.api.nvim_set_current_win(win)
            end
          end, 101)

Obviously just waiting 101ms is a bad workaround, but I couldn't quickly find a good hook or event to use. The wait time is selected to outwait the initial sleep as well as because that's what worked for me.

You still don't get best results because the cursor will be on the wrong line in the summary panel, but you should see it expanded at least.

Hey there @guruor @hjdivad

Here's a solution that doesn't use a hard coded sleep time and select correctly the focused test:

            vim.api.nvim_create_autocmd("User", {
                pattern = "NeotestSummaryOpen",
                callback = function()
                    vim.defer_fn(
                        function() vim.api.nvim_set_current_win(vim.fn.bufwinid("Neotest Summary")) end,
                        1
                    )
                end,
            })

The "NeotestSummaryOpen" user event pattern can be found here, now if we don't apply a defer_fn with 1ms of delay it won't work, will select the root element.

No idea why the 1ms delay works, but it works 🙂
