stdin broken with fish shell

[rsyring]

The stdin integration when using the fish shell is broken. Any command that runs from .envrc and requests input from the user seems to hang direnv. I came across this trying to use aws-vault ... and needing to put in an MFA code. But I have reproduced it with a simple read command.

Here is a docker setup to demonstrate the problem: https://github.com/rsyring/fish-direnv-stdin-bug

The same setup with bash runs just fine:

 ❯ docker compose run --rm --build fish-shell
root@bd0c85efe474 ~# cd example/
direnv: loading ~/example/.envrc
test: direnv: error signal: killed

root@bd0c85efe474 ~/example# cd
root@bd0c85efe474 ~# bash

root@bd0c85efe474:~# cd example/
direnv: loading ~/example/.envrc
test: foobar
response: foobar
root@bd0c85efe474:~/example#

I was just about to open an issue for the same problem. Simply adding this to my .envrc recreates the error:

$(read -p "Enter text: " text)

No keystrokes will appear and enter does nothing. I can ctrl-C out of it though. I tried also on bash, zsh, an nushell and they were able to read input correctly.

Ah. This has been a problem for quite some time I see #967

Does anyone know a workaround for this?

I posted a lengthy description of a workaround here:
