Regex matching

Postby Davin Church » September 26th, 2018, 11:51 pm

Since )FNS and friends now have Regex matching, is there some Quad function available for us to do matching and/or replacing from our applications? I've often liked to have that, but never had enough time to build my own tools for it.

Which RegEx engine? There are dozens.

Would be useful - in the Find and Find/Replace functionality of the editor.

I'm not really sure it would matter to me, but something flexible and popular (popularity has its reasons). But I was expecting to get whatever they were already using for )FNS.

Some Regex systems also allow replacement as well as searching, which would be a nice benefit, but may be a little tricky to implement.

RegEx is one of those things that remind me to heed the warning be careful what you wish for, you might get it.

It is one thing that I have to learn afresh every time I use it.

What works for SQL Server's LIKE and PATINDEX does not work for NOTEPAD++ and does not work for DOS's FINDSTR and does not work with C# ... the list goes on (or the other way round). The number of times I locate the RegEX patterns on the internet (usually for Python) only to find that it does not work in my context!
