CLOSED - RegEx EOF needed

Bob Hansen · Post by **Bob Hansen** » Thu Mar 19, 2009 3:44 am

I work with another product that uses a RegEx engine. It has the value of \z that represents EOF. I don't see an EOF pattern in Perl or EasyPatterns. Any chance of createing that capability for us?

Is very useful to add footers to files and to truncate files.

\Z is standard Perl RegEx for "Assert position at very end of string". It therefore *IS* supported by Macro Scheduler's RegEx implementation.

The EasyPatterns keyword for \Z is [textEnd]. for \A it is [textStart]

Let>pattern=\A[a-z]+\Z
RegEx>pattern,joe,0,matches,num,0

Thanks for that Marcus.

I was used to thinking of string management on a line by line basis. I had used \Z like $. It never occurred to me to try it on an entire file vs. individual lines.

I already have http://www.regular-expressions.info as one of my RegEx references, I have just missed that \Z for EOF for all these years.

I learn something new every day here. Luv it!
