Discord username (optional)

No response

Shell and Version

fish shell 3.3.1

Operating System and Version

macOS Monterey 12.3.1

I have tried commenting out my system & user rcfiles and warp still will not bootstrap

Yes

Screenshots

Warp raised an error when I tried to use SSH, the screenshot is shown below. Thanks for your great software.

The command I used in the screenshot is like `ssh username@ip -oPort=xxxx`. By the way, the same command works fine under zsh.

Include shell xtrace output

Man.. I spent hours trying to figure out WTF was wrong with my fish.config on my SSH host. I couldn't find any trace of this code in any of my functions, plugins, etc. Turns out it's an issue with warp. 🤦

elviskahoro · 2022-07-08T19:24:54Z

From @SichangHe via #1054
Same problem

ssh username@ip
username@ip's password:
fish: Unsupported use of '='. In fish, please use 'set hook $(printf "{\"hook\": \"SSH\", \"value\": {\"socket_path\": \"~/.ssh/15932\", \"user\": \"%s\", \"machine\": \"%s\", \"remote_shell\": \"%s\"}}" $(whoami) $(hostname) ${SHELL##*/} | command xxd -p | command tr -d "\n")'.
Connection to ip closed.

I have the same issue as @elviskahoro , would like to be able to use the warp ssh wrapper with fish shell on my remote machines. for now I've fallen back to bash on the remote machines, but I want to use fish.

fish 3.5.1 on macOS Monterrey 12.5

SerenadeX · 2022-09-26T15:44:13Z

I am still having this issue as well. macOS Monterey 12.6, fish shell 3.5.1

sebastiandeutsch · 2022-11-24T21:11:23Z

The problem still exists. I'm ssh onto a server with fish as default and I'll get this error:

fish: Unsupported use of '='. In fish, please use 'set hook $(printf "{\"hook\": \"SSH\", \"value\": {\"socket_path\": \"~/.ssh/25958\", \"user\": \"%s\", \"machine\": \"%s\", \"remote_shell\": \"%s\"}}" $(whoami) $(hostname) ${SHELL##*/} | command od -An -v -tx1 | command tr -d " \n")'.

using

ssh -vvvv ...

Will give you slightly more info.

What does this hook do? It actually looks a bit shady.

cezarmathe · 2022-12-28T16:13:35Z

Is fish over SSH going to be a thing?

nihaals · 2023-02-28T14:14:06Z

It would be nice if ssh -t host bash worked as a workaround (currently it just does nothing in terms of Warp)

ajnart · 2023-03-02T23:59:55Z

I also want this ! Do you have an ETA ? Currently I am using /usr/bin/ssh to start SSH sessions with my server that uses fish shell.

mboyd1 · 2023-06-19T03:31:14Z

since Warp seems so keen on collecting user telemetry data here's a free telemetry signal for you, this remote server fish issue completely blocks me from using your product

dannyneira · 2023-07-17T23:01:36Z

hey folks, Sorry about the delays on this. If it's any consolation you can add the following line to your remote config.fish:

if status is-interactive
  printf '\eP$f{"hook": "SourcedRcFileForWarp", "value": { "shell": "fish"}}\x9c'
end

then use /usr/bin/ssh to ssh into the remote fish machine and Warp features should work.

Then I get "Starting shell..."

Just upgrade Fish to 3.6.1 with the following command (if you are using Ubuntu LTS):

sudo apt-add-repository ppa:fish-shell/release-3
sudo apt update
sudo apt upgrade fish

It works! :D

Still doesn't work. Time to uninstall warp and try again in a few months. I can't have a split workflow. It's cool enough I am willing to check it out every few months, but not use when basic functionality I would use is broken.

Almost all of my shell work is on remote systems. Warp is useless without the shell integrations through SSH to me. Might as well keep using iTerm, which I am more familiar with.

Well. You misunderstood our solution.

Disabling remote shell integration will only disable the automatic Warpify code injection of SSH. It does not affect the manual Warpify operation.
Then, we write the correct Warpify code in our Fish initialization script, ~/.config/fish/config.fish: SSH - Support Fish for remote machines #871 (comment).
Using the normal SSH way to sign in your machine. Your initialization script will work as what Warp's injection code does, and Warp shell will start warpify your shell.

So don't worry – even disabling the option, it won't affect the integration of Fish if you have written the Warpify code in your config.fish. Just make sure the version of your Fish is at least 3.6.

lexpierce · 2023-10-07T20:36:44Z

Ok, so it’s a partial solution for my personal systems. It does make fish seem like a secondary priority which gives me long term worries.

I’ll give it a try and see if it’s truly worth adding to a larger scale template deployment. It looks like it’s safe but must test all changes.

efc · 2023-11-18T18:00:07Z

I am trying the manual Warpify code for fish and that does get me into the remote with a fish shell, however there are still some rather unfortunate gaps when working with the remote fish shell.

When I use Warp with a local fish shell, fish can cleverly supply autocompletes for anywhere in the filesystem. For example, if I make a new directory with mkdir silly and then type ls s fish will suggest ls silly automatically.

However, when I use Warp with a remote fish shell, fish is not nearly as clever. When I get to the ls s step in the scenario above, fish will not suggest ls silly. Note, if I visit the same remote fish shell using Terminal, then fish happily fills in the brand new directory name for me. Also, once I complete the command for the first time, then fish is able to predict that completion just fine, even in Warp. But the effect is that the first time I visit any new path using Warp and remote fish shells I am "flying blind".

So clearly, even when it "works", Warp is interfering with the fish shell on the remote system in a way that is problematic.

Does anyone have suggestions of what might be going wrong?

I just tried the "show background blocks" feature and it shows a radically different behavior when on a local machine vs. a remote machine. When I type ls s on a local terminal in Warp, there are no extra blocks shown. But on the remote host Warp is running this warp_run_generator_command script on every keystroke:

case "${SHELL##*/}" in
zsh) set -o nullglob;;
bash) shopt -s nullglob; GLOBIGNORE=.:..;;
esac

for f in .* *; do
file_type=\'File\'
if [ -d "$f" ]; then
    line="{\"file_name\": \"$f\", \"file_type\": \"Directory\"}"
else
    line="{\"file_name\": \"$f\", \"file_type\": \"File\"}"
fi
printf "$line\n"
done

I suspect this is what is causing Warp to fail to show Fish autocompletes properly.

Interested by this, I asked chatGPT to translate it into a fish-compatible script and it gave me the following

switch (basename $SHELL)
    case 'zsh'
        set -q GLOB_NOMATCH; and set -e GLOB_NOMATCH
    case 'bash'
        set -q GLOB_NOMATCH; and set -e GLOB_NOMATCH
        set GLOBIGNORE . '..'
end

for f in .* *
    set file_type 'File'
    if test -d $f
        set line "{\"file_name\": \"$f\", \"file_type\": \"Directory\"}"
    else
        set line "{\"file_name\": \"$f\", \"file_type\": \"File\"}"
    end
    printf "$line\n"
end

Not sure of how good it is but maybe there is a way to overwrite this function and make it use a fish-compatible one?

Adding my anti-fish experiences here

https://app.warp.dev/block/5uVCeEoLsOS1XjVWGwN0rZ
https://app.warp.dev/block/PM5Vq7PMbOu0FyfwjJGMrZ

If my default shell is fish on remote host, (fish, version 3.6.4), the whole thing blows up. I changed the default shell to bash, and it worked, but on the remote host if I simply launched bash, it blows up.

I would like to try helping fix this, but I can't figure out where this warp process cuts in, or where the scripts are kept.

publicqi · 2024-01-12T00:35:57Z

Are you planning to fix it though?

shirok1 · 2024-04-21T16:32:43Z

The SourcedRcFileForWarp for fish is still literally half-baked. Support for $() is only added after 3.5.0 (released June 16, 2022) and shouldn't be take granted if you ever want to connect to Linux servers running stable distributions...Have you guys at Warp actually tested it?

[ -z $WARP_BOOTSTRAPPED ] && eval 'export WARP_HONOR_PS1=0; export WARP_COMBINED_PROMPT_COMMAND_GRID=0; set -g WARP_SESSION_ID (random);set _hostname $(command -v hostname >/dev/null 2>&1 && command hostname 2>/dev/null || uname -n);set _user $(command -v whoami >/dev/null 2>&1 && command whoami 2>/dev/null || echo $USER);set _msg $(echo -n "{\"hook\": \"InitShell\", \"value\": {\"session_id\": $WARP_SESSION_ID, \"user\": \"$_user\", \"hostname\": \"$_hostname\", \"shell\": \"fish\", \"is_subshell\": true}}" | od -An -v -tx1 | command tr -d " \n");echo -n \u1b\u50\u24"d$_msg"\u9c;set -e _hostname _user _msg;'

It could have work, if the $s are removed!

[ -z $WARP_BOOTSTRAPPED ] && eval 'export WARP_HONOR_PS1=0; export WARP_COMBINED_PROMPT_COMMAND_GRID=0; set -g WARP_SESSION_ID (random);set _hostname (command -v hostname >/dev/null 2>&1 && command hostname 2>/dev/null || uname -n);set _user (command -v whoami >/dev/null 2>&1 && command whoami 2>/dev/null || echo $USER);set _msg (echo -n "{\"hook\": \"InitShell\", \"value\": {\"session_id\": $WARP_SESSION_ID, \"user\": \"$_user\", \"hostname\": \"$_hostname\", \"shell\": \"fish\", \"is_subshell\": true}}" | od -An -v -tx1 | command tr -d " \n");echo -n \u1b\u50\u24"d$_msg"\u9c;set -e _hostname _user _msg;'
