Regex regression?

A lot is happening, so I could be off here. In the 10496 web image, I noted that there might be problems with the regex package. Now trying to build a new image I hit a walkback over

'*username*' asRegex

Any other takers? I am seeing this problem in both 10496 and the new RC1 on the download page.

Yes!!! Is the same error I saw trying to install Seaside2.8 as it uses exatly that

I already contact Dale few days ago to see if he could look at it. Lukas ?

Re: Regex regression?

Installing Seaside is how I hit it also. I also _suspect_ something wrong elsewhere. I use SIF to get my code out of Dolphin and into Pharo. Between those steps, I edit the "raw SIF" and began using regex for the task. It's not going well lately, and this increases my suspicion that it is not my doing.

I will try to capture what I did as a test case.

No wonder, this expression is invalid. If this is from some old code, then
probably it's a result of half backed migration from #match:. If it's
your code, then try '.*username.*' asRegex.

There are quite a few unresolved bugs in the regexp engine, but this
is definitely not one of them.

The problem is that this is not a valid regular expression. See the
wikipedia article for a general description
(<http://en.wikipedia.org/wiki/Regular_expression>) or the
documentation on the class side of RxParser for a specific description
of the Smalltalk implementation.

Your code looks more like a String>>#match: pattern.

Thanks Lukas and Levente.

Dale, can we update this?

It's not my code - it's from ConfigurationOfSeaside28.
