[Closed] Regular Expressions … HELP

Start imagining
There is limited pattern matching for strings (the method is called matchPattern someString pattern:“somepattern”), but it is not a full-featured regex implementation. There are enough parsing methods to do what you want in MAXScript though, so this hasn’t stopped anyone from coding in Max.
Since MAXScript was developed to work mostly inside of (surprise!) Max, it does not provide some features general scripting languages used at OS shell level provide. At the same time it provides Max-related methods from the field of 3D math and graphics other scripting languages do not necessarily need.

Huh? Really? I must have missed something…

Incidently, a Frantic Films extension which ships with the free Amaretto bridge to NVidia’s Gelato renderer provides full regex support. I will investigate what the exact interface name and methods were tomorrow…

Ok, the interface is called Frantic and is exposed by the Amaretto plugin which ships (in Beta) with the free Gelato renderer by nVidia.

Interface: Frantic

Examples:

Frantic.RegExSearch “a;lsjaeoi5r” “^[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$”
RESULT:
undefined – not an email

Frantic.RegExSearch “abc@def.com” “^[a-zA-Z0-9._%-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$”
RESULT:
#() – matches the pattern completely

Frantic.RegExSearch “abc@def.com” “^([a-zA-Z0-9._%-]+)@([a-zA-Z0-9.-]+.[a-zA-Z]{2,4})$”
RESULT:
#(“abc”, “def.com”) –sub-patterns matched

Frantic.RegExSearch “@abc@def.com” “^([a-zA-Z0-9._%-]+)@([a-zA-Z0-9.-]+.[a-zA-Z]{2,4})$”
RESULT:
undefined –does not match, since we are checking from beginning ^ to end $

Frantic.RegExSearch “@abc@def.com” “([a-zA-Z0-9._%-]+)@([a-zA-Z0-9.-]+.[a-zA-Z]{2,4})”
RESULT:
#(“abc”, “def.com”) –this matches, because we don’t check from beginning to end
