Ideally, I don't want to add new ya sub / ya sub-static because it overlaps with the functionality of yazi --remote-events, which means maintaining an additional set of code with identical functionality, something I'd prefer to avoid if possible.

Can you describe the issues you encountered when reading the output of yazi --remote-events in Neovim, ex what was the code like? I'll try it later to see if I can make it work.

The error I get is the following:

   Info  18:42:06 notify.info stderr: "\27[?1004l\27[?2004l\27[?1049l\27[0 q\27[?25hError: Device not configured (os error 6)\n"
   Info  18:42:06 notify.info stdout: nil

I realize it's not much to work with. Here's a code snippet that causes that error for me:

    local events_job = vim.system({ 'yazi', "--remote-events='hover'" }, {
      text = true,
      stderr = function(_, data)
        vim.notify('stderr: ' .. vim.inspect(data))
      end,
      stdout = function(_, data)
        vim.notify('stdout: ' .. vim.inspect(data))
      end,
    })

The error does not occur if I start lazygit instead (just as a test).

Just rebased to main and resolved all conflicts. No change in functionality was made.

The suggestions have now all been addressed. However, some odd issues now remain that I would like to see fixed:

• if no server is running, the command fails (I actually don't mind this myself)

• when starting, some old events are reported every time on startup:

  These seem to be from very old sessions and I'm not sure why they are still being reported.

• when yazi closes and reopens, no events are ever reported again. I think this makes sense as for the new yazi instance, the handshake has not been done. However, I would like to be able to reestablish the connection. Do you have advice how this could be done?

Yeah this is the expected behavior.

when starting, some old events are reported every time on startup:

Try rm ~/.local/state/yazi/.dds and see if it still. This may be related to the dirty data tested before.

When next_line() returns None, it means that the server has stopped. At this time, you can call Stream::connect() to try to re-establish the connection (if other servers are started), but you need to add time::sleep() for each attempt to avoid CPU consumption caused by fast failure

Thanks for the instructions! I was able to implement reconnecting, and it's much better now.

However, there is some odd behaviour when starting up: about 2000 empty messages are received.

As a proof of concept, I added a hacky counter to display the number of the current message. Here's a very short demo:

I'm not sure what this might mean. Could you try this out and see if you get the same behaviour?

Why is this PR closed?

There are two reasons:

1. it's been open for a long time and I'm starting to forget little details and
   ideas
2. I'm no longer convinced it will be a good idea. In my use case with neovim,
   this would enable real time event reading, and thus writing a few minor
   features. But what I have in mind for the neovim integration (which I wrote
   about in Increase possibilities for yazi<->embedding editor integration #989) would require a deeper
   level of integration, such as RPC.

I could maybe see such an integration layer being implemented in lua, perhaps
also as a yazi plugin, but right now I consider this "lua route" blocked by
(although all of these are totally solvable issues!)

• lack of typing for yazi apis (difficult to write lua bindings without them)
• lack of testing facilities in yazi plugins (hard to write features and
  maintain them)
• lack of versioning for yazi apis (upcoming breaking changes in yazi could
  break plugins without a clear way to detect this)
• uncertainty about what your vision for yazi is regarding these things (hard to
  justify the effort)

As you explained in
#1057 (comment), I think in
general yazi is still taking shape. It's probably best to wait and simply
reimplement it later, or do something completely new.
