问题
Is it possible to have a regex expression match with a pattern that finds a word and then also matches with any other occurrences of that word?
To be more explicit, lets say I have some language that declares variables with a # like #varName
I also have the regex expression (?<=#)\w* to locate such words.
However, in another part of my code I use varName without the # and thus cannot identify it using the same method.
So my question is, can I write one regex expression to locate varName in both instances?
My intention is to use this to write a syntax definition for sublime-text, so I am using textmate's regex syntax.
