Hi Daniel Shahaf,

Thank you very much for responding. To get some context to my use case you
can check:

https://stackoverflow.com/questions/64416625/can-not-use-some-of-my-aliases-with-bare-repo

Long story short, as far I know, there is no easy way to use some of my
aliases with bare repo. There are some solutions like special git alias
like:

example1 = "!f() { .....; }; f"

However, I am feeling much comfortable with this approach. Here, I am
trying to change my command on the fly by running it before accept-line.
The widget is working perfectly for me except, it is not saving the
original buffer in the history.

I need a command or widget like *save-to-history *so that I can use it the
following way:

if [[ $BUFFER =~ ^"g d untrack-all" ]]
then
*zle save-to-history $BUFFER*
BUFFER="g d rm --cached -r ~"
zle .accept-line
....

That way I can save the value of the $BUFFER in the .zsh_history file in
proper format.

And yes you are right when you said:

I'd scratch the approach of checking [[ $BUFFER =~ '^g d foo' ]],

But, this script is only for my personal use, so I will continue tweaking
it as per my requirement.

Being said that, I actually do not know how to check PREBUFFER before
checking BUFFER. I will be glad if you can give me some code to fix this
issue.

*Thanks and Best Regards,Ahmad Ismail*
