Regular Expression to replace CGRectMake

Question

As CGRectMake is not available in swift 3.0 and migrator did not convert it i need to manually replace it and it is used more than 300 times in my code so can anyone help me in this to develop regular expression so i can find and replace code. What i want to do is to convert

CGRectMake(a,a,a,a) here a is some value.

to

CGRect(x: a, y: a, w: a, h: a)

Answer 1

Find by this:

CGRectMake\(([^,]*),([^,]*),([^,]*),([^,]*)\)

and Replace by this:

CGRect\(x:\1, y:\2, w:\3, h:\4\)

Tried it in notepad++
