Subject: 31.0.50; Can't activate bash-ts-mode without a shebang
Date: Sat, 15 Mar 2025 06:41:10 +0000

[Message part 1 (text/plain, inline)]

If i try to activate bash-ts-mode in a file without a shebang, it
falls back to using shell-mode with zsh indentation.

Steps to reproduce:

1. emacs -Q
2. Clear out the scratch buffer from any text and paste this code into
the scratch buffer:

add_service() {
ln -s "$service_path" /var/service/
echo "Service is added:"
service_name=$(basename "$service_path")
ls -la /var/service/ | grep "$service_name"
}

3. If bash treesitter grammar isn't available, i usually install it
through the `treesit-install-language-grammar` command with all the
default options.
4. M-x bash-ts-mode

It returns this message "Indentation setup for shell type zsh", and
instead of using bash-ts-mode it uses sh-mode.

Now, if you add a shebang above like '#!/bin/sh' and try to activate
bash-ts-mode again, emacs will activate it.

The problem here is that this is probably the reason why i can't use
bash-ts-mode with org-babel, it always falls back to sh-mode when i
define a code block with bash-ts-mode.

I cannot reproduce this with today's master branch.  Your build seems
to be from an old (Jan 20) checkout of the master branch, so please
try to sync from upstream and then see if the problem persists.

I've tried to build with the latest commit, the end result is the same. I also tried to install the latest stable version of emacs (30.1) using nix. Same thing.

I attached a video snippet.

There's no need for video clips, I believe you.  I just cannot
reproduce this.

Could this be due to some outdated or newer grammar library?

Or maybe this is specific to GNU/Linux for some reason?

Can someone please try reproducing this and debugging it?  Yuan?

I guess that’s because your default shell is bash. On my machine, my default shell is fish, so it falls back to sh-mode too. When bash-ts-mode is enabled, it does an extra check to see if the file is actually bash, if it can’t be sure, it falls back to sh-mode. See sh--redirect-bash-ts-mode. 

If you enable bash-ts-mode in a file that ends with “.sh”, it should stay in bash-ts-mode.

I did this:

```
(defun my-sh--guess-shell ()
  "/bin/bash")
(advice-add 'sh--guess-shell :override #'my-sh--guess-shell)
```

Looks like it does what i want in my case.

So can we close this bug, or is there something else left to do here?

I think what bash-ts-mode does right now is reasonable, so closing the bug.
