Antlr的贪婪模式语法

Submitted by gougou on Mon, 2005-08-29 09:43

.-noscript-blocked { border: 1px solid red !important; background: white url("chrome://noscript/skin/icon32.png") no-repeat left top !important; opacity: 0.6 !important; }

CURLY_BLOCK_SCARF
    :   '{' (.)* '}'
    ;
 
要想让Antlr能够匹配}，我们需要将规则改为

Delphi调用VC生成用于C程序调用的DLL的注意事项

Submitted by gougou on Sat, 2005-08-27 16:45

在VC中可以Export DLL函数供C程序调用

#define PARSERDLL_API __declspec(dllexport)

extern "C" {
PARSERDLL_API int GetSqlType(LPCTSTR szSql);
}

Delphi要想调用这样的针对C输出的函数，不能使用stdcall的调用规范，而应使用cdecl的调用规范

如何include预编译头文件到antlr生成的cpp中

Submitted by gougou on Sat, 2005-08-27 09:33

在Antlr生成cpp文件时，我们可能希望添加预编译头文件StdAfx.h到cpp文件中，标准的Header开关只能把头文件include到生成的头文件，而不能是cpp文件。

要想添加头文件到cpp中，需要使用antlr cpp生成器特殊控制开关关键字pre_include_cpp，示意如下
header "pre_include_cpp" {
#include "StdAfx.h"
}

关于DailyBuild

Submitted by gougou on Thu, 2005-08-25 06:38

在XP开发理念中，很重要的就是要能够Daily Build，主要的理由是频繁的发布，频繁的获得反馈。但是从实际开发过程中来看，在开发的不同阶段，对于DailyBuild的需求是不一样的。在原型开发阶段，大家都在忙着写自己的部分，所有的模块还无法组装到一起时，DailyBuild其实没有什么意义，测试人员即便拿到了DailyBuild的时候，也无法进行集成测试。
