Remapping keys to a command that requires input

[Eloitor]

Hi,

I want to send lines from helix to tmux. For this I wrote this script:

$ cat tmux-send-stdin.sh
#!/bin/sh

# Get the session name from the command line argument
session="$1"

while read -r command; do
    tmux send-keys -t "$session" "$command" Enter
done

I wanted to create a map for shell_pipe_to such as

[keys.normal]
A-a = ["shell_pipe_to", "tmux-send-stdin.sh session-0"] 

output when running hx:

Bad config: No command named 'tmux-send-stdin.sh session-0' for key `keys.normal.A-a` at line 23 column 1
Press <ENTER> to continue with default config

The main problem is that shell_pipe_to requires the user to enter the program to use, but I don't know if this is possible to emulate with a keymap. I found this similar use case: https://www.reddit.com/r/HelixEditor/comments/xde3f1/remapping_keys_to_a_command_that_requires_input/

Is this possible to do currently? Is this planned? Is there a better solution to send commands to tmux?

This is why :pipe-to was added. You should be able to map to :pipe-to tmux-send-stdin.sh session-0

Thanks for the answer. I get

Bad config: No TypableCommand named ':pipe-to tmux-send-stdin.sh session-0' for key `keys.normal.A-a` at line 18 column 7
Press <ENTER> to continue with default config

I have version 22.12

Looks like it's not in a release yet, it was merged after 22.12: #4931

While I'm waiting for the release I found this solution:

$ cat tmux-send-stdin.sh
#!/bin/sh

# Get the session name from the command line argument
session="$1"

while read -r command; do
    echo "$command"
    tmux send-keys -t "$session" "$command" Enter
done

And in the config:

[keys.normal]
A-a = ":pipe tmux-send-stdin.sh session-0"

Can we close this as it's already solved with pipe-to plus a duplicate of #1383 for keys that require input
