TMUX support

[zachlloyd]

Right now blocks and input don't work within tmux sessions.

The most likely way we would support this is through tmux's control mode feature, like iTerm, where it would integrate with split panes.

https://github.com/tmux/tmux/wiki/Control-Mode

Posting here to get a sense of how useful this would be. Please give it a thumbs up if you'd like it.

[alokedesai]

For anyone interested in this feature, we're running some focus groups to understand this use-case a little bit better. We would love for you to join if you are interested: https://calendly.com/aloke-warp/tmux-focus-group?month=2021-08&date=2021-08-18

[alexkubica]

Hi I'm a tmux & warp user and would like to join the focus group and perhaps test beta features once you have a draft.
The calendly link doesn't work anymore.

The first thing I do is enter a tmux session, always! Having everything in one window is so satisfying. Using keybindings that work on all stock tmux configurations is also crucial for me as system admin. If Warp can't work with that in the way to expect, I won't give it a shot.

[elviskahoro]

From @kendallm
During SSH:
"The window offset for the top of the window covers the first line of text. This isn't usually an issue using the Warp as normal, but attaching to a tmux session in a remote terminal this creates a bit of a UX issue. See attached screenshot.

To Reproduce
Steps to reproduce the behavior:

Create a tmux session in another terminal window
In warp, type tmux attach -d
See screenshot below
Expected behavior
I would expect the viewport for terminal window not be obstructed by the tab bar."

[elviskahoro]

@thomasmarcel - #156 support starting tmux by default

Describe the bug

"I have some functions to open a new tmux session or reattach it when a new terminal session is opened, but it keeps crashing Warp on zsh startup.

I tried with no `.tmux.conf` file, with less logic, only opening a new session, same error.

Opening a tmux session after Warp finishes loading works fine.

To Reproduce

Steps to reproduce:

Add the line below to your .zshrc

tmux new-session -As "test"

Launch Warp

Expected behaviour

The terminal starts as expected and opens a tmux session."

[elviskahoro]

from zheng:

To clarify, does it crash - or does it show this modal?

We've been meaning to make this modal less intrusive (show a toast instead). I also think it may make sense for us to avoid showing it if the user's in a full screen program

[elviskahoro]

from thomasmarcel

It freezes and shows the modal, precisely!

[elviskahoro]

mapping the left option key to meta on M1 Macbook Air wouldnt work when using Tmux in Warp.
Im trying to use it to switch panes with h/j/k/l and it works correctly in nvim but not in a tmux terminal pane.

[jimmyhmiller]

I can't start tmux sessions. I can attach to them. But when I try to start them in warp I just get.

tmux
[exited]

The exit code is 0. Kind of makes warp unusable for me sadly.

[jimmyhmiller]

For what it's worth, things seem to be working for me now on the latest release.

[odyslam]

Yeah me too, heavy tmux/vim user, and I loved warp from what I was told.

I usually use tabs in tmux and panes in vim

[dannyneira]

Split Panes may help with this your case. https://docs.warp.dev/features/split-panes

[maiaz]

Unfortunately no. As tmux keep your remote sessions, and open new pane in warp and then ssh is a little bit painful…

[SC7639]

I use tmuxinator to set up my projects and open all the panes and windows I use. It would be great to have the features of the warp in tmux

[dannyneira]

Give Launch Configuration feature a try for your use case. https://docs.warp.dev/features/session-management/launch-configurations

[nielsk]

That is not the same. If I accidentally close my window, I can just "tmux a" and have the session open again. I can even log out of my graphical session and can log back in again, open a terminal, "tmux a" and there is my session. I have a shell script I start that will configure my Lay-out in tmux and start several programs in the correct layers.

I have the same shortcuts for splitting and navigating tabs and windows across multiple terminals and machines (where my tmux.conf exists) across Linux and macOS. Headless or not.

[nielsk]

Regarding that shell-script - that works also on a headless machine which I regularly ssh into from iOS-devices where Warp is not available.

[praisedare]

This shell-script of yours sounds really cool. Do you have it in a public repo or gist? I'd really like to have something like that as I use vim/tmux a lot for my projects.

[LEI]

Plugins can help restoring sessions, for example https://github.com/tmux-plugins/tmux-resurrect saves the current state locally.
This way each host can have a different (and dynamic) layout.

I have an alias to attach or start a new session, usually one per host:

#!/usr/bin/env bash

if ! hash tmux 2>/dev/null; then
  return
fi

t() {
  if [[ $# -ne 0 ]]; then
    tmux "$@"
  elif [[ -n "$TMUX" ]]; then
    tmux new-session -d
  else
    tmux attach || tmux new-session
  fi
}

if hash _tmux 2>/dev/null; then
  complete -F _tmux t
fi

[haranrk]

Same here, would love to have tmux support in warp

[josecanhelp]

Tmux support would be fantastic. I pretty much only use tmux in my terminals.

[JLHasson]

Similarly, tmux+{mosh, ssh} is almost equivalent to the terminal for me.

[SharkBaitDLS]

Yeah. I love the idea of Warp but my setup is so ingrained into Tmux

[tbezman]

I wouldn't mind leaving my tmux workflow if warp supported something like "Workspaces". Basically offering what tmuxinator does.

Right now when I use warp, I just have like 10 tabs open. Usually 2 tabs per project (general command stuff, and then lazygit in the other tab). I just want to be able to switch to a different project without having to remember which tab group I was in.

[rumanHuq]

This along with detached mode would be so darn cool!

[dimfeld]

EDIT: moved my comment to the session management topic, but it talked about how Warp could do session management features that would completely replace my tmux usage.

[petervanderdoes]

Would love to see support for tmux like iTerm2, tmux sessions are opened in tabs

[nielsk]

I don't even need special tmux-support like iTerm because that is tbh not working well for me, but in tmux all the special features of warp are gone apparently. And the first thing I do when I open up my computer and open up the first terminal is to start a shell-script that sets up my environment in tmux for me with multiple tabs, splits and starting some programs.

[MichaelRBond]

Same. I start tmux from my .bashrc file, and stay in that one tmux session all day.

[fwip]

My day-to-day workflow involves connecting back to long-running tmux sessions - some on my local machine, and many on a remote machine that I access over SSH. Ideally, for me, the solution that Warp lands on would work as well with remote tmux sessions as it does with local sessions.

[krak3n]

This is my workflow as well.

[jum]

Even local sessions are tmux in my use case as I want my sessions to survive when I log in or out. Not that I log in or out often, but at least when MacOS force me to do that to cope with a bug in the GUI I at least still have my command windows where I left them.

[wayneeseguin]

I also often leverage this workflow.

[joehannes]

Here's my 50 cent (as mentioned in another issue here):

I usually prefer tmux to profiles/sessions, because tmux to me was the well established go to product #1 ... plus

• tmux is independent, like it or not, if I someday prefer another terminal or need another terminal ... I can use my profiles/sessions as of tmux there out of the box as well
• there's plugins for tmux
• community
• docs

I still don't use warp because I can't go tmux-fullscreen and tmux-statusline rendering isn't good either ...

However I want to propose something that I think would be useful, plus feasible if still early days as of sessions/profiles (which I heard isn't (fully??) implemented yet):

• Why not use the established .tmux.conf for simulating the tmux-statusline in the top tabline???
  I am an avid status/powerline-user and would really like to see custom components and fancy tabs in the tabline, along with the possibility to hide a tabline with 1 tab/no-components only.

If you want to support tmux better anyway and possibly need to integrate with tmux somewhat and plan to have sessions & profiles in the future, why not simply instead of -- take care, persuasive wording ahead

• inventing your own schema nobody knows, a brand new one that takes some time to architect properly
• maintain that schema and extend it as the community thrives
  parse and simulate/emulate tmux.conf and tmuxinator.yml?? instead
  You get:
• a well estabished schema that's being used by I guess a good percentage of all the CLI geeks out there
• being maintained and developed by an existing community
• open source, meaning you can contribute if the need arises or the community wants something (also giving to OSS)
• you can even fork-extend it should you need to ...

[brandondrew]

this is the way

Great points! I fully agree this is the way. I don't think any deeper integration is needed.

[pdonorio]

Hi team! 👋
Just like the others this is a blocker on using warp.
And this is the top voted (by far) in the roadmap,
may we please just get some information on ideas/progress
or eventually get confirmation if it won't be done? thanks 🙏

[mohwildan]

tmux support

[7flash]

I need tmux only to manage background processes, not interested in its layout features. Perhaps, Warp can offer alternative solution where I can throw any of my tabs into sidebar to send the process into background, or something if it makes sense.

[onionka]

Please don't make me go back to iTerm2 just because of missing TMUX support (iTerm2 sux compared to Warp 😭 ).
I am using tmux locally (can leave it be if needed) and on servers (on multiple layers, but we depend on this one), so this is big blocker for me too.

[cshintov]

Don't think this is a priority for them, can we try to implement this as Warp is OSS?

[cshintov]

Oh! It's not OSS! 😔

[Richigeht]

I would also really welcome this especially considering you are releasing tmux for Linux soon!
I could get around on Mac - but not on Linux (servers) which is also especially my issue for business cases.
The one non-linux Mac guy at work already use warp 😭

Though I bet they are smart enough to release tmux support with Warp Linux or shortly after ✌️

[AJReade]

++ for this, I need the ability to send keys/text to specific windows, the current synchronise in warp doesn't cut it unfortunately, I also need the ability to spawn background processes. I'd love more transparency on calling the underlying function of warp to open sessions using bash scripts rather than fixed warp commands.

[alor]

my only annoyance of using tmux/screen via ssh with warp is that I cannot scroll with the mouse wheel to see the output of a command that is longer than the current screen, when I scroll I just get a bunch of:
^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B^[[B

this is my only real blocker for warp vs iterm2.
huge productivity loss if I cannot scroll back the output of commands

[martin-braun]

Are you serious? You use tmux, you know that you can scroll using ... ehm ... tmux?

PREFIX[ and simply using vim motions.

[alor]

I can set -g mouse on to scroll. but it's not default. have you ever tried iterm2 with ssh + screen or tmux? no need to do anything and you can just scrollwheel the buffer like local terminal

[dannyneira]

Feedback from an avid tmux user

Should you guys choose this route, a few hurdles to win over the tmux junkies:

• a background process or daemon for window management
  • the window manager ought to not kill itself when warp terminal disappears.
  • this is immensely important for remote, high-performance computing. tmux allows panes with running code to remain active on the remote computer even if:
    • the ssh connection dies out of the blue
    • or ubuntu gdm3 seppukus itself
• and secondly, there should be some ability to save and resurrect collections of sessions, windows, and panes. If the computer turns off, it is wildly convenient to resurrect an entire collection of pane collections with their running programs (see tmux-resurrect)
