Incompatibility with custom config setopt globsubst

[fdelavier]

Hi,

I notice an issue when using zsh-history-substring-search plugin with my existing zsh customizations.

Indeed, in my .zshrc I typically use this configuration :
setopt globsubst

Problem: this option breaks zsh-history-substring-search when using "eval" build-in command.

First, enter this eval command :

% eval $(echo date +"%D")
11/01/22

So now this command is in the history.

Then, without option globsubst, we can use the Up key (click many times on this key)

% unsetopt globsubst

% [click on Up key several times]

=> OK

But now, with option globsubst, if we click 3 times on the Up key :

% setopt globsubst

% [click on Up key 3 times]

% eval $(echo date +"%D")
_history-substring-search-begin:46: missing end of string

=> history call fails after the eval command.

Maybe zsh-history-substring-search should use something like "emulate -L zsh" ?

According to man zshoptions :

       LOCAL_OPTIONS <K>
              If this option is set at the point of return from a shell  func‐
              tion, most options (including this one) which were in force upon
              entry to the function are restored; options  that  are  not  re‐
              stored  are PRIVILEGED and RESTRICTED.  Otherwise, only this op‐
              tion, and the LOCAL_LOOPS, XTRACE and  PRINT_EXIT_VALUE  options
              are  restored.   Hence  if  this  is explicitly unset by a shell
              function the other options in force at the point of return  will
              remain  so.   A shell function can also guarantee itself a known
              shell configuration with a formulation like  `emulate  -L  zsh';
              the -L activates LOCAL_OPTIONS.

Thanks
