tmux (and other providers) was killed

[PhantomYdn]

That's so unfortunate and force me to stick to older version. But... Why? Server approach is not a replacement for providers - it's just different approach with less functionality as for me.

So - any way to make tmux work again with the plugin?

#186

See the commit message for reasoning: 82332cf

Server approach is not a replacement for providers - it's just different approach with less functionality as for me.

It supports all the same behavior (or should - lmk if I missed something), just requires more user configuration. Which is unfortunate, but ultimately more pragmatic here 🙂

As fact, TMUX provider doesn't work for me any more after update. AI said that that provider cofiguration is "dead code" because providers were "killed" according to source code.

Of course it doesn't work, it was removed from plugin code... but you can externally configure opts.server yourself to use tmux. Please see the links in my other comment 🙂

Mentioned code (https://github.com/e-cal/opencode-tmux.nvim) also target to older version of opencode.nvim:( It expects for example opencode.cli.server. So there is no drop-in solution. I have to reuse some of the approaches for my config.

Thanks for sharing your solution! I hope to add a more stable configuration option someday for plugins like that to leverage.
