Eclipse Regular expression Lookup and substitution

CTRL + space in the textboxes gives your all kinds of suggestions for regular expression writing.

Find

Replace

Be sure to check out the \c regular expression operator, which I think are specific to Eclipse.

It saves a lot of work in replacing the same word in upper-case, lower-case, and CamelCase variants.

For example, if the original text is:

Someobject Someobject Someobject;

Then doing a "Replace all" replacing

Someobject

with 

\cAnotherobject

Would get you:

Anotherobject anotherobject = Anotherobject;

I had an old method with hundreds of lines doing calling a getattribute ("X") and casting the result to a string.

(string) Object1.getattribute ("X") (string) Object2.getattribute (" Y " ) (String) Objectn.getattribute ("Z")

I had to change them any to use a new method, which checks if the attribute is null. So the new line would is

Getsafestringattribute (Object1,"X") Getsafestringattribute (object2,"  Y") Getsafestringattribute (objectn,"Z")

With the simple regEx you can do a replace all!

Find :

\ (string\) (. +) \.getattribute\ ("(. +)" \)

Replace: Getsafestringattribute ($ "$")

The first (. +) would match the Objectx part while the second would match the attribute name.

The best thing is the If you select some text and

Type CTRL + F (if the Regular Expressions checkbox is ticked)

You string in the find would be a already escaped from characters like ' (', ') ' etc!
