@skovhus Is there anything else you need me to do in order to get this looked at?

Sorry, I completely missed this one.

There are some CI errors here related to outdates snapshots. Can you have a look?

shfmt needs to be installed in order for the tests to pass. I've updated the GitHub Actions workflow to install it. I haven't tested this, but it should work. If there are still issues with this run then I'll raise a pull request within my fork and debug.

Still some issues here.

The version of shfmt packaged on Ubuntu 22.04 is 3.4.3, which doesn't support long options. Switched to use short options now. This is a good catch, as there are likely lots of users running that version (or older).

All checks passed on my forked repo, so third time lucky...

Should it use -ln posix/-ln bash depending on whether the script is POSIX/bash?

Similarly, I believe the -s (simplify) option is missing from the configuration.

It's a month since I looked at this in detail. I did consider setting dialect, but shfmt's autodetection looked pretty good and setting a config option probably wouldn't be the right way for over-riding this on a per-script basis.

Similarly, I believe the -s (simplify) option is missing from the configuration.

Again, that was deliberate decision. The 'simplify' option doesn't just change formatting - it changes the code itself. That didn't seem like something a user would expect to happen when they format a document.

Having said that, if the community feels strongly that that option should be there it probably wouldn't be much effort for me (or someone else) to add it.

In Helix now with 5.3.1 when I save a ZSH file with auto-format on it deletes the contents of the file and saves an empty file. When I used shfmt by itself as an external formatter for Helix I did not have this problem: https://github.com/helix-editor/helix/wiki/Formatter-Configurations#shfmt

This might be an unrelated problem as I understand this language server is not compatible with ZSH, but it might be of interest. Helix shows that there are parsing errors, but it still more or less worked before enabling LSP formatting:

Could you share a (minimal) example file so that I can look into this from the shfmt/bash-language-server side please? Also, which version of shfmt are you running?

shfmt --version 3.6.0 on Debian 12.

Here is the file that when formatted goes blank. Just load it info Helix and use :format. Afraid I just changed everything back to the old setup so don't have time to go back and make this a minimal example file:

Yes, this is a bug. I've opened issue #1162 to track this, and raised PR #1163 to fix.

@chris-reeves It is all fixed now, thanks for your prompt reaction!
