<
tool> (PCCTS) A highly integrated
lexical analser generator
and
parser generator by Terence J. Parr <

Will E. Cohen and Henry G. Dietz <

of
Purdue University.
ANTLR (ANother
Tool for Language Recognition) corresponds to
YACC and DLG (DFA-based Lexical analyser Generator) functions
like
LEX. PCCTS has many additional features which make it
easier to use for a wide range of translation problems. PCCTS
grammars contain specifications for lexical and syntactic
analysis with selective
backtracking ("infinite lookahead"),
semantic predicates, intermediate-form
construction and
error reporting. Rules may employ
Extended BNF (EBNF)
grammar constructs and may define parameters, return values,
and have
local variables.
Languages described in PCCTS are recognised via
LLk parsers
constructed in pure, human-readable,
C code. Selective
backtracking is available to handle non-LL(k) constructs.
PCCTS
parsers may be compiled with a
C++ compiler. PCCTS
also includes the
SORCERER tree parser generator.
Latest version: 1.10, runs under
Unix,
MS-DOS,
OS/2, and
Macintosh and is very portable.
