Is it possible to suppress the output of a register? For example, I am using getchar() to 'consume' a character, but I don't need it to return anything. I suppose I could add in a hackish ternary operator to do this, such as:

=getchar()?'':''

But I was wondering if there was a cleaner or better way to do this?

  • "cleaner" is subjective, but getchar()[-1] is shorter.

  • @user938271 thanks. Do you want to post an answer and show how that would work? Does the -1 work differently than for example it does in python?

"cleaner" is subjective, but getchar()[-1] is shorter.

From :h expr-[]:

A negative index always results in an empty string (reason: backward compatibility).
