From e37c8ef903e49e33defdcb5197862161a9dbe420 Mon Sep 17 00:00:00 2001 From: "shanjian%netscape.com" Date: Thu, 14 Mar 2002 00:47:05 +0000 Subject: [PATCH] #125628 Auto-detect can not detect the gb18030 page above properly This patch added a state machine for gb18030 verification. The data of the state machine is created based on GB18030 standard, and the code was generated by a perl script which is almost identical to rest of the perl script that generated other header files. Rest of the code is just adding this state machine to some charset detectors. r=ftang, sr=shaver, a=asa git-svn-id: svn://10.0.0.236/trunk@116509 18797224-902f-48f8-a5cc-f745e15eee43 --- mozilla/intl/chardet/src/nsGB18030Verifier.h | 109 +++++++++++++++++++ mozilla/intl/chardet/src/nsPSMDetectors.cpp | 3 + mozilla/intl/chardet/src/nsPSMDetectors.h | 7 +- mozilla/intl/chardet/tools/gengb18030.pl | 40 +++++++ 4 files changed, 156 insertions(+), 3 deletions(-) create mode 100644 mozilla/intl/chardet/src/nsGB18030Verifier.h create mode 100644 mozilla/intl/chardet/tools/gengb18030.pl diff --git a/mozilla/intl/chardet/src/nsGB18030Verifier.h b/mozilla/intl/chardet/src/nsGB18030Verifier.h new file mode 100644 index 00000000000..2a01f143f04 --- /dev/null +++ b/mozilla/intl/chardet/src/nsGB18030Verifier.h @@ -0,0 +1,109 @@ +/* -*- Mode: C; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 2 -*- */ +/* ***** BEGIN LICENSE BLOCK ***** + * Version: NPL 1.1/GPL 2.0/LGPL 2.1 + * + * The contents of this file are subject to the Netscape Public License + * Version 1.1 (the "License"); you may not use this file except in + * compliance with the License.
