I've plenty fill and want to find all of them which are like this:
A = A + B
So I wanna use a regular expression using M + x rgrep
. and was thinking to something like that: ([A-Za-z][A-Za-z0-9]*) = () + [A-Za-z][A-Za-z0-9]*
where ()
create a group which can be used latter.
Their is a way to make a regular expression where two item must be the same but without knowing the form of them?
