最安全的方法来改变项目中的变量名 [英] Safest way to change variable names in a project
问题描述
所以我一直在做一个相对大的项目，我自己，我已经认识到，早些时候的一些变量名是..不太理想。
So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal.
但是，如何轻松地改变项目中的变量名？有没有这样一个工具，可以通过一个项目目录，解析所有的文件，然后将变量名称替换为所需的一个？
But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine.
我在想使用regexp（sed / awk on linux？）工具来替换变量名，但是有很多次我的特定变量也被包含为字符串的一部分。
I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings.
还有一个关于改变c ++命名空间的东西的问题，因为实际上有两个
There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces.
我记得视频工作室能够做到这一点，但是最安全和最优雅的方式是什么
I remember visual studio being able to do this, but what's the safest and most elegant way to do this on linux?
推荐答案
最安全（非自动化方式）：
Safest (non automated way) way:
- 确保所有的单元测试都正常工作。
- 将所有内容保存到源代码管理中。
- 全球用XXXvarXXX（认真）替换var
a。或者也许只是你认为需要编辑的文件。 - 尝试并编译。无法编译的一切都很容易撤消，只需删除XXX。
- 编译时运行单元测试。
- 单元测试工作时。将XXXvarXXX全局替换为新名称。
- 确保单元测试仍然有效
- 将所有内容保存在源代码管理中。
- Make sure all your unit tests work.
- Save everything into source control.
- Globally replace var with XXXvarXXX (seriously)
a. Or maybe just the files you think need editing. - Try and compile. Everything that does not compile is easy to undo just remove the XXX.
- When it compiles run the unit tests.
- When the unit tests work. Do a global replace of XXXvarXXX to the new name.
- Make sure the unit tests still work
- Save everything in source control.
