еще один компилятор компилятора (РАЗРАБОТКА) (yet another compiler compiler (DEVELOPMENT))
Описание (Description)
The yacc utility shall read a description of a context-free
grammar in grammar and write C source code, conforming to the
ISO C standard, to a code file, and optionally header information
into a header file, in the current directory. The generated
source code shall not depend on any undefined, unspecified, or
implementation-defined behavior, except in cases where it is
copied directly from the supplied grammar, or in cases that are
documented by the implementation. The C code shall define a
function and related routines and macros for an automaton that
executes a parsing algorithm meeting the requirements in
Algorithms.
The form and meaning of the grammar are described in the EXTENDED
DESCRIPTION section.
The C source code and header file shall be produced in a form
suitable as input for the C compiler (see c99(1p)).
