Return immediately when running in Zsh

This might sound weird, but some users choose to source this script for both Bash and Zsh. I think it doesn’t harm to have something like this in the beginning:

if [[ -n $ZSH_NAME ]]; then
    return
fi

@FranklinYu thanks for the feedback! This should already be accounted for in:

bash-preexec/bash-preexec.sh

Lines 321 to 324 in 7884535

    
           # Make sure this is bash that's running this and return otherwise. 
        
           if [[ -z "${BASH_VERSION:-}" ]]; then 
        
               return 1; 
        
           fi

This line should effectively cause this script to exit with 1 when trying to source with zsh or any shell other than Bash. Please let me know if I'm mistaken.

Thank you very much. I have noticed this line, but it is very late in the script. At that time all the functions and variables are already there. How about moving this 4 lines to the top?

Noticed this when you first posted, but didn't give it much thought. Thanks for the feedback! Updated in #114 Let me know if you have something else in mind.

	# Make sure this is bash that's running this and return otherwise.
	if [[ -z "${BASH_VERSION:-}" ]]; then
	return 1;
	fi
