SolidityPreprocessor

This project is related to the preprocessor that rewrites solidity code. Provide the user with the keyword nonfallback so that the user can indicate that the fallback function should not be called. When the user displays the intention using the keyword, it uses the if condition statement to check the status variable and informs the user whether to call the fallback function. The preprocessor adds new contracts and state variables to know if the fallback function is called.

Example) A Sol source file (including “NONFALLBACK” keyword)

 contract Caller {     function callTest(Test test) public {         test.call(0xabcdef01 , NONFALLBACK); // hash does not exist     } } 

The code above will look like the code below after passing through the preprocessor.

 contract Caller {     function callTest(Test test) public {         forFallback ffb = new forFallback();         test.call(0xabcdef01 , NONFALLBACK); // hash does not exist         if(ffb.getData = 1){           throw;         }     } } contract forFallback {   uint private getfb = 0;   function setData(uint a) public { getfb = a; }   function getData() public returns(uint) { return getfb; } }

固体再加工机

此项目与重写solidity代码的预处理器有关。为用户提供关键字nonfallback,以便用户可以指示不应调用fallback函数。当用户使用关键字显示意图时,它使用if条件语句检查状态变量,并通知用户是否调用fallback函数。预处理器添加新的协定和状态变量,以了解是否调用了回退函数。

示例)一个Sol源文件(包括“NONFALLBACK”关键字)

 contract Caller {     function callTest(Test test) public {         test.call(0xabcdef01 , NONFALLBACK); // hash does not exist     } } 

上面的代码在经过预处理器后将与下面的代码类似。

 contract Caller {     function callTest(Test test) public {         forFallback ffb = new forFallback();         test.call(0xabcdef01 , NONFALLBACK); // hash does not exist         if(ffb.getData = 1){           throw;         }     } } contract forFallback {   uint private getfb = 0;   function setData(uint a) public { getfb = a; }   function getData() public returns(uint) { return getfb; } }
