Javascript解析器v8库入门
1) 签出源代码
svn checkout http://v8.googlecode.com/svn/trunk/ v8
2)在v8根目录下签出gyp
svn co http://gyp.googlecode.com/svn/trunk build/gyp
3)在v8根目录下签出python和cygwin
svn co http://src.chromium.org/svn/trunk/tools/third_party/python_26@89111 third_party/python_26
svn co http://src.chromium.org/svn/trunk/deps/third_party/cygwin@66844 third_party/cygwin
4)添加python和cygwin的路径到环境变量
set path="%cd%\third_party\python_26";"%cd%\third_party\cygwin\bin;%path%
5) 生成编译项目文件(gyp是json配置文件和python脚本的工具集，是一个元编译系统，用来生成真正的编译系统，比如常见的Makefile, *.sln, *.vcproj 等）
python build\gyp_v8
6) 打开编译项目编译(在命令行里面用start方式打开sln文件，可以让visual studio编译系统继承环境变量)
start build\all.sln
7) 编译
在 build/{debug,release}/lib 下得到4个静态库文件(windows上默认也是静态库文件)
preparser_lib.lib
v8_base.lib
v8_nosnapshot.lib
v8_snapshot.lib
头文件在v8根目录下的include文件夹里面
8) 测试
testv8.cxx
// testv8.cpp : Defines the entry point for the console application.
//
#include <v8.h>
using namespace v8;
int main(int argc, char* argv[]) {
// Create a stack-allocated handle scope.
HandleScope handle_scope;
// Create a new context.
Persistent<Context> context = Context::New();
// Enter the created context for compiling and
// running the hello world script.
Context::Scope context_scope(context);
// Create a string containing the JavaScript source code.
Handle<String> source = String::New("var x='xyziamheres2///sdfsdf123'; x.match(/\\d{3,3}/);");
// Compile the source code.
Handle<Script> script = Script::Compile(source);
// Run the script to get the result.
Handle<Value> result = script->Run();
// Dispose the persistent context.
context.Dispose();
// Convert the result to an ASCII string and print it.
String::AsciiValue ascii(result);
printf("%s\n", *ascii);
return 0;
}
在testv8.cxx所在目录下新建文件夹
v8/inc
v8/lib/debug
v8/lib/release
把生成lib文件和头文件一起复制到相应的目录
9) 编译测试testv8
cl /Od /I "v8/inc" /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /MDd /Fo"Debug\\" /Fd"Debug\vc90.pdb" /W3 /c /ZI /TP ".\testv8.cpp"
