vim hanging when using SlimuxREPLSendLine

[arifb]

Hello, Great plugin, invaluable to me. Having issues however, may have been on upgrade to iTerm2 3.0, not sure.

When I issue a SlimuxREPLSendLine, MacVim is unresponsive, with the cursor remaining in the vim command line (bottom).

Looking at running processes, seems to be tmux load-buffer -b Slimux - the command that is causing the hanging. Killing that allows me to continue using vim.

Obviously I'm not able to send text out to the REPL however.

Are you using tmux 2.2? It's a known issue: see https://github.com/tmux/tmux/pull/416 and try this workaround. :neckbeard:

[arifb]

@sunaku Appreciate the tip - I am using tmux 2.2. Setting that environment variable doesn't do the trick however. I will try to pull in your patch and recompile tmux later today.

[arifb]

Rebuilt tmux including https://github.com/tmux/tmux/pull/416 and the issue persists. If there is more debugging that would be helpful to provide, please let me know.

[sunaku]

Oops, I missed the fact that you're on a Mac. :sweat_smile: The workaround and patch you tried only apply to Linux. Report this issue upstream at tmux: it might be a Mac-related issue that they (have yet to?) know about.

Hi @arifb did you managed to find a way around the problem. I'm having exactly the same issue after updating tmux and trying to export EVENT_NOEPOLL=1 as suggested in the link above. Did you have any luck in fixing the issue? I'm also using OS X.

[arifb]

@gzagatti I downgraded to tmux 2.1 for now

[gzagatti]

Yes @arifb I did the same and it works.

[sunaku]

Okay, I've got it! :neckbeard: MacOSX users, please try these settings with tmux 2.2:

export EVENT_NOKQUEUE=1
export EVENT_NOPOLL=1

These magic environment variables come from tmux's MacOSX-specific osdep_event_init() function, whose source code is available at https://github.com/tmux/tmux/blob/2.2/osdep-darwin.c#L77-L78.

Note: This is the same approach I followed for solving this issue in tmux 2.2 running under Linux. :penguin:

Thanks @sunaku it works like a charm

@arifb can you confirm that it works? I also just pushed a change that lets you specify the path to your tmux, this should allow for better flexibility.

I had an issue with the same symptoms when the tmux session was running one version and slimux found a tmux of another version, hopefully either the mention above or the configuration will alleviate the problem.

@slashfoo not sure if for @arifb worked, but I tried in tmux 2.2 and worked like a boss! 👍 Without those envs, vim crashes like described above.

[slashfoo]

thanks @hlegius I'll close this issue then.
