在C ++中通过函数调用替换cast [英] Replace cast by function call in C++

问题描述

重构/替换转换的工具或方法的任何建议，例如：

Any recommendations of a tool or method to refactor/replace casts such as:

(type*) data

into：

convert_to_type(data)

data 有更高优先级的运算符，括号或换行符：

Things become trickier when data has higher priority operators, parenthesis or line breaks in it:

(type*) a(b)->
              c

应成为 convert_to_type（a（b） - > c）不是 convert_to_type（a）（b） - > c 等。

推荐答案

我不知道有一个工具能够自动正确解析和替换。

I'm not aware of a tool that's able to properly parse and replace these automatically.

意识到是使用g ++与 -Wold-style-cast 这将有助于警告你所有这样的C风格的演员，允许你通过分析代码正确处置问题。这显然比工具需要更多的时间，但它也给你机会审查和防止工具做错误的转换。

The best option I'm aware of is to use g++ with -Wold-style-cast which will then helpfully warn you for all such C-style casts, allowing you to disposition them properly by analyzing the code in question. This will obviously take more time than a tool but it also give you the opportunity to review and prevent a tool from doing an incorrect conversion.
