vim call function on a group in substitute string

Question

how to call a function from the substitute string in vim? When i have:

%s/regex/string/g and i want the group as argument and replace it with the return value of the function:

%s/regex/call function(\1)/g so the group #1 will be the argument of the function, and the return value of the function will replace all the matches in buffer.

is it posible?

To use a vimscript expression you need to add \= to your replacement string:

%s/regex/\= function(submatch(1))/g

@microo8 Thanks for your comment. I've added the missing `submatch` call to get `\1`. – jcollado Mar 01 '12 at 09:06

Note see ``:h sub-replace-expression`` for more details. – Bryce Guinta Nov 27 '16 at 23:16

This somehow does not work when there is a character before the function call. – Behlül Aug 04 '22 at 21:17
