ViewLoader

Com problemas para definir a navegação com formulários e frames da sua aplicação? Cansado de usar TTabControl e TTabItems para compor a UI do seu App mobile ou desktop? A transição SLIDE do TTabControl é legal, mas já está muito batida? Cansado de usar TFrame como classe base para suas views? No FMX até um TEdit pode ser usado como componente agregador, então que tal usar TLayout, ou qualquer outro componente derivado no lugar? Quer mais liberdade para manipular suas listas de views, sem abrir mão de controle? ViewLoader.

Oz-CocoR-Delphi

Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.
