Retrieve RegEx Pattern From A EReg Insance As A String

[AlienCoder]

Hello Community,

is it possible to return the regEx pattern string of an EReg object once it is instanced?

To become more concrete:

I am resolving a string that consists of integers seperated by one or many none-word-character(s).

var regEx : EReg = ~/([0-9]+)(\W+[0-9]+)+/;
var string = "33#44#22#31";

This is just a radical simplification. The regular expression check in my code is a little more complex. And there are different checks to be done. To keep the procedure a little more simple I would like to re-use the regEx pattern and complement it with some additional regEx statements.

It seems the EReg api has no method for that purpose.

So, is it possible to get the part "([0-9]+)(\W+[0-9]+)+" from the regEx instance as a string?

Kind regards
Michael

From what I can tell there is a private var `r` that you could use @:access with and use toString() to get the value, I'm thinking this is private for a  reason and might not exist on every target. I had a similar problem in the past and just ended up storing the string and creating the regex through the constructor when it was needed.

Here is what i was able to acheive in extracting regex from EReg instance on all Haxe targets: https://github.com/RealyUniqueName/HUnit/blob/master/src/hunit/match/ERegMatch.hx#L56
