From 9aeaed383b0ce7d578251ff5765b8c94d1b3f167 Mon Sep 17 00:00:00 2001 From: H.G. Muller Date: Wed, 2 Mar 2011 22:14:57 +0100 Subject: [PATCH] New parser, written in C A new parser was written to replace the flex-generated one. Immediate improvements are that it understand double-digit rank numbers, and Shogi coordinates. No changes were made in the Makefile yet to reflect the new, flexless building procedure. --- parser.c | 4831 ++++++++------------------------------------------------------ 1 files changed, 575 insertions(+), 4256 deletions(-) diff --git a/parser.c b/parser.c index a87313f..407b92e 100644 --- a/parser.c +++ b/parser.c @@ -1,4256 +1,575 @@ - -#line 3 "parser.c" - -#define YY_INT_ALIGNED short int - -/* A lexical scanner generated by flex */ - -#define FLEX_SCANNER -#define YY_FLEX_MAJOR_VERSION 2 -#define YY_FLEX_MINOR_VERSION 5 -#define YY_FLEX_SUBMINOR_VERSION 35 -#if YY_FLEX_SUBMINOR_VERSION > 0 -#define FLEX_BETA -#endif - -/* First, we deal with platform-specific or compiler-specific issues. */ - -/* begin standard C headers. */ -#include -#include -#include -#include - -/* end standard C headers. */ - -/* flex integer type definitions */ - -#ifndef FLEXINT_H -#define FLEXINT_H - -/* C99 systems have .
