Descripción del Proyecto

Yappy provides a lexical analyser and a LR parser generator
for Python applications. Currently it builds SLR, LR(1), and
LALR(1) parsing tables. Tables are kept in Python shelves for
use in parsing. Some ambiguous grammars can be handled
if priority and associativity information is provided.

En las especificaciones de la gramática, la separación entre las reglas semánticas (dentro de (())) e información de precedencia. Las normas de la semántica de un bisonte con argumentos semánticos se llevaron a cabo: E -> E + T (( "Suma ($ 0, $ 2 )"}}. Manejo de algunas excepciones en LRparser fue corregido.

In grammar specifications, separation is made
between semantic rules (inside {{ }}) and
precedence information. Semantic rules a la Bison
with semantic arguments were implemented: E -> E +
T {{ "Sum($0,$2)"}}. Handling of some exceptions
in LRparser was corrected.
