splitting camel case?

[PA <petite.abeille@...>]

Hello,

Does anyone have a simple pattern to split camel case strings?

For example:

"componentWithName" -> { "component", "With", "Name" }

Here is what I have presently:

( "componentWithName" ):gsub( "%u?%l+", print )

> component
> With
> Name

However this doesn't quite cover all potential cases, specially  
acronyms (e.g. "componentWithURL"):

Also, is the "frontier pattern" aka "%f" something which is officially  
supported? It doesn't seem to be documented anywhere beside this wiki  
page:

http://lua-users.org/wiki/FrontierPattern

Ideas?

Cheers
