I've noticed that there is a problem when using `%m` in vcs_info,
where the default `get-applied-string` hook returns something with
backticks in it:

While the backticks can be replaced in the prompt itself, it might be
better to quote it in `VCS_INFO_git_handle_patches`:
diff --git i/Functions/VCS_Info/Backends/VCS_INFO_get_data_git w/Functions/VCS_Info/Backends/VCS_INFO_get_data_git
index ee50be6..371e935 100644
--- i/Functions/VCS_Info/Backends/VCS_INFO_get_data_git
+++ w/Functions/VCS_Info/Backends/VCS_INFO_get_data_git
@@ -121,7 +121,7 @@ VCS_INFO_git_handle_patches () {
if VCS_INFO_hook 'gen-applied-string' "${git_patches_applied[@]}"; then

- git_applied_s=${git_patches_applied[1]}
+ git_applied_s=${(qqq)git_patches_applied[1]}
else
git_applied_s=""
fi
There is probably a better place to apply the quoting, e.g. when reading
the patches from the file, or a more central place in vcs_info, because
this is likely to affect other backends, too.
Regards,
Daniel.

And there is no such commit in zsh's git repository.

I don't think we should post-process these values. The hooks should
return properly quoted data (I suppose your problem is that your hook
does returns a - maybe even single - backtick and you use the
prompt_subst option which would cause problems) as the rest of the
configuration requires.
Correct me if I'm missing something.

You are right - there is no default hook, but the default handling in case of no hook.

The commit is not in zsh's history, but in another private/local repo/branch.

I've added an own gen-applied-string hook, which quotes the value, but the default behavior is to get the data via:
elif [[ -d "${gitdir}/rebase-merge" ]]; then
patchdir="${gitdir}/rebase-merge"
local p
for p in ${(f)"$(< "${patchdir}/done")"}; do
# remove action
git_patches_applied+=("${${(s: :)p}[2,-1]}")
done
The quoting needs to get applied to all places where the Git sources are being read in Functions/VCS_Info/Backends/VCS_INFO_get_data_git then probably, and also in the code for other VCS (e.g. hg).

That's correct.

Daniel.

That's not a zsh commit, it's an example from some other software's
git repository where the log message happens to use backticks.

I guess we could introduce a function that does some form of
post-processing , if a style is set. Valid settings could be "quote" or
"strip" and "function", the latter would dispatch to a named function,
for example for the user to get full control. That function could be
used everywhere where a string from an external program is used.
That way, prompt_subst users (if you don't use prompt_subst, which is
the default, none of this is an issue) can get post-processing if they
like. Actually, we could make the default depend on the state of the
option when vcs_info initialises.
Unfortunately, I can't look into it right now due to lack of spare time.
Regards, Frank
