nvim chezmoi edit returns exit status 134

[kaddkaka]

What exactly are you trying to do?

Editing a tracked config file with nvim and closing it with :wq will cause chezmoi to return with exit status 134 when this autocmd is present in my nvim config:

autocmd BufWritePost /tmp/chezmoi-edit*       silent! !chezmoi apply --source-path "%"

As recommended from https://www.chezmoi.io/user-guide/tools/editor/#configure-vim-to-run-chezmoi-apply-whenever-you-save-a-dotfile (except the filename is changed to the one used when invoking e.g. chezmoi edit .config/nvim/init.vim)

The problem is not seen when saving and quitting separately: :w :q.

The problem is not seen with vim

$ nvim --version
NVIM v0.9.0-dev-1254+g84027f751
$ vim --version
VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Apr 03 2023 07:45:49)

Where else have you checked for solutions?

I tried to find documentation about exit status, but I didn't find any.

• [x] I have read chezmoi's user guide, and not found the answer.
• [x] I have searched chezmoi's reference guide, and not found the answer.

Additional context

Doing the same change with vim and the same autocmd does not cause the bad exit status:

$ EDITOR=vim chezmoi edit .config/nvim/init.vim
$

Doing the changes "manually" in the `~/.local/ folder and vim/nvim gives no surprising exit status:

$ vim ~/.local/share/chezmoi/dot_bashrc
$ echo $?
0
$ nvim ~/.local/share/chezmoi/dot_bashrc
$ echo $?
0

(using this autocmd: autocmd BufWritePost ~/.local/share/chezmoi/* silent! !chezmoi apply --source-path "%")

[kaddkaka]

Oh, I realized having silent! on the !chezmoi external command was a bit stupid. And now I see this error when trigger the autocmd with :w:

"/tmp/chezmoi-edit391288291/.config/nvim/init.vim" 149L, 4739B written
:!chezmoi apply
chezmoi: open /dev/tty: no such device or address

shell returned 1

What to make of that?

[twpayne]

Presumably you're using a password manager that requires a password to store your secrets?

chezmoi: open /dev/tty: no such device or address means that chezmoi is trying to get a TTY to read your password manager password, but NVIM doesn't allow this when you run :!chezmoi apply.

[kaddkaka]

Almost, it was asking for what to do with another tracked file that had diffs (diff/overwrite/skip).

vim shows the prompt, but I'm not sure if I was able to interact with it, it seems to trigger on the first key stroke (which might be the default behavior, e.g. o means overwrite)

[twpayne]

Running chezmoi apply outside of NVIM should reveal exactly why chezmoi needs a TTY. It may well be the "file has changed since chezmoi last wrote it" warning. You can run chezmoi apply --force instead if you're feeling lucky.

Also consider chezmoi edit --watch and see https://www.chezmoi.io/links/related-software/.

[kaddkaka]

so I updated my autocmds to be:

autocmd BufWritePost ~/.local/share/chezmoi/* ! chezmoi apply --source-path "%"
autocmd BufWritePost /tmp/chezmoi-edit*       ! chezmoi apply

so that when editing a file directly under ~/.local/ only that file is applied. However I'm not sure if anything similar is possible with the /tmp/chezmoi-edit* so I left it with the "catch-all" command chezmoi apply. This has the drawback of applying changes to all files, not just the one being edited.

[kaddkaka]

Thanks for pointing out related software. The Lilja plugin should work for the chezmoi edit invocation as it uses ugly code to get the cmdline from the parent pid to extract the dotfile being edited:

if stridx(l:parentPidFileSplitted[0], l:chezmoiBinary) != -1 && l:parentPidFileSplitted[1] == "edit"
  let l:dotfile = l:parentPidFileSplitted[-1]

Would it be possible for the chezmoi edit command to modify the actual file under ~/.local/share/chezmoi/ instead of a temporary file? That would simplify some of this.

[twpayne]

Would it be possible for the chezmoi edit command to modify the actual file under ~/.local/share/chezmoi/ instead of a temporary file?

Yes and no.

Yes: chezmoi edit invokes your editor with a filename equal to the target file name and a hardlink target of the source file, i.e. chezmoi edit already edits the file in the actual file under ~/.local/share/chezmoi/.

No: this only works if the file is not encrypted. With encrypted files, chezmoi edit transparently decrypts and re-encrypts them for you.

i.e. this is already the case.

[kaddkaka]

Right, so is it possible to get the ~/.local/share/chezmoi/-path from the /tmp/chezmoi-edit1361922538/.config/nvim/init.vim?

Since chezmoi apply --source-path works with the first kind of path, but not the second.

[kaddkaka]

I guess the following is useful to find the source file:

$ find "$XDG_DATA_HOME"/chezmoi/ -samefile /tmp/chezmoi-edit332538725/.config/nvim/init.vim 2>/dev/null
$XDG_DATA_HOME/chezmoi/dot_config/nvim/init.vim

I am not sure what this means exactly

chezmoi edit invokes your editor with a filename equal to the target file name and a hardlink target of the source file, i.e. chezmoi edit already edits the file in the actual file under ~/.local/share/chezmoi/.

in vim/nvim, the name of the file being edited (the name of the buffer at least) is the tmp name, and I'm, not sure if target file name is available anywhere.

• :args is /tmp/chezmoi-edit332538725/.config/nvim/init.vim
• % contains /tmp/chezmoi-edit332538725/.config/nvim/init.vim

[twpayne]

The target path is visible after the temporary path, i.e. remove the /tmp/chezmoi-edit332538725/ prefix.

You can use the target path with chezmoi apply if you don't pass the --source-path flag.

[kaddkaka]

Oh! That's quite obvious now that you point it out. How is that tmppath generated (i.e. chezmoi-edit332538725)? Would this pattern substitution be a good enough way to extract the interesting part? s?/tmp/chezmoi-edit[0-9]*/??, as used in:

fnamemodify(expand('%'), ":s?/tmp/chezmoi-edit[0-9]*/??")

Also I just found the chezmoi edit apply command (https://www.chezmoi.io/user-guide/frequently-asked-questions/usage/), does that make the above vim autocmds redundant?

[twpayne]

How is that tmppath generated (i.e. chezmoi-edit332538725)?

/tmp comes from $TMPDIR (depending on your OS), the chezmoi-edit prefix is set by chezmoi, and the suffix is randomly generated. However, any or all of the above might change from OS to OS or from chezmoi version to chezmoi version.

Would this pattern substitution be a good enough way to extract the interesting part? s?/tmp/chezmoi-edit[0-9]*/??

No, for the reason above.

Also I just found the chezmoi edit apply command (https://www.chezmoi.io/user-guide/frequently-asked-questions/usage/), does that make the above vim autocmds redundant?

Pretty much. You should also look at the --watch flag and the edit.watch config variable.

Hopefully this is now resolved. Please re-open if needed.
