Some questions about test running in nvim 0.10 and the plugin configuration in general

[x1a0]

Thanks for this great plugin!

Since upgraded NeoVim to 0.10, I noticed that when running all tests (via runnables), it does not show the split window any more. This seems due to in 0.10 the test executor is default to background.
Hence I have 3 questions:

• To bring back the "old" way, should I set test_executor = executors.termopen?

• If above is correct, where should I set it? Based on README I think I need to have this somewhere:

  vim.g.rustaceanvim = {
    tools = {
      test_executor = executors.termopen
    }
  }
  

  In the README it says:

  The options shown below are the defaults. You only need to pass the keys to the setup function that you want to be changed, because the defaults are applied for keys that are not provided.

  But in the README it also emphasizes that setup should not be called. So I am a bit confused that where should I put this table so it'd be correctly loaded. (I use Lazy btw).

• And another question is, how can I configure it so the testables/runnables executions run in a split window to the right (so a vertical split)? They are shown in the top window in a horizontal split by default it seems.

Thanks again!

Hey 👋

That quote from the readme was outdated rust-tools documentation that I forgot to remove. This plugin doesn't have a setup function.

You can set the test_executor using a string alias:

vim.g.rustaceanvim = {
  tools = {
    test_executor = 'termopen',
  },
}

It doesn't really matter where you put the table. This plugin will read from it when you open a rust file.

lazy.nvim users typically define it in the init or config function of the plugin spec.

Currently, horizontal splitting for termopen is hard coded, I'm afraid. But PRs are welcome 😀
You can also open a feature request, but I might need some time to implement it, as I don't use the termopen executor myself.

Thanks! I put it in config now and everything seems good 👍

Regarding the background mode (or maybe about "executions" in general), if say something is running in background, is it possible to "attach to it by split a window"? For example if I invoke a runnable, and press ECS while the cursor is in the runnable window, it'd close the window, but the process is still running in background. In my case it's a http server so it'd still be occupying the port. I realized that I could re-run it so it'd kill the prev process and start a new one. However I wonder is it possible to attach to the old process again somehow.

The background test_executor is only intended for tests, not runnables in general.
With the termopen executor, I don't think you can reattach (unless the buffer is still open, but hidden, in which case it would be a question of finding and switching back to the buffer).
The toggleterm executor (requires the toggleterm plugin) should be able to reattach, using the :Toggleterm <id> command, where <id> is the ID of the terminal (numbered starting from 1).

Come to think of it (I'm not 100 % sure), it may be able to configure toggleterm in such a way that this plugin's toggleterm executor opens in a vertical split.
