Conditionals in function strings?

PaoloFCantoni · Apr 19, 2006#12006-04-19T10:51+00:00

The ^{A^}^{B^} - matches expression A or B

I can only get it to work in a Function string with literal A or B.

Can the expression be used inside the ^( ^) tag?

Secondly, can the expression be a generalised expression or only a literal?

A worked example would be really helpful.

TIA
Paolo

Both questions: No!

^{A^}^{B^} is extremly limited. You cannot really use it with other regular expression conditions neither inside the brackets nor outside. For a really full featured OR you would need Perl compatible regular expression. Sorry!

Thanks Mofi.

My experiments suggested this, but I was hoping I had missed something...

For those of you interested in conditionalisations in Function strings, I had a bit of a "lateral think" and came up with this (for C#):

/Function String 3 = "%[ ^t]++[publicrvaten]+[ ^t]+^([clasenumrt]+[ ^t]+[a-zA-Z0-9_]+^)"

If you look at the funny character ranges:
[publicrvaten]+ will match: public private internal
and
[clasenumrt]+ will match: class struct enum

This allows me to list classes, enums and structs in the functions list.

Hope this helps someone...
