How to use regular expressions for variables with text in vimscript?

Question

I have text stored in a variable, for example, for example:

let text = getline(line(".")-1) 

How to check if text matches regular expression? I expect something like this:

 let text = getline(line(".")-1) if regexp_match(text, "^[Ss]tuff$") dostuff endif 

Answer 1

I did some more research and found out that I need = ~ # operator , which is used to check if some text matches the regular expression:

 if "text"=~#"^te.." echo "Matches!"
