从变量名中删除 m_ 前缀
最初，我们计划采用旧的约定，为类变量添加 m_ 前缀。但现在要求将所有m_VaribaleName替换为this.variableName，即删除m_并使m_后面的第一个字符小写。
我可以搜索并用它替换 m_ 。但这不会将变量的第一个字符重命名为小写。搜索和替换后，如果我使用重构工具将 VariableName 重命名为variableName，这也会重命名已存在的 VariableName 属性。
我想知道是否有任何正则表达式、工具、宏可以使此任务自动化。
Initially we planned to have old convention of having m_ prefix for class variables. But now requirement has come to replace all the m_VaribaleName to this.variableName, i.e. remove the m_ and make the first character after m_ lowercase.
I can search and replace m_ with this. but this doesn't rename the variable's first character to lowercase. After search and replace if I use re-factoring tool to rename VariableName to variableName this also renames the property already exists with VariableName.
I am wondering is there any regex, tool, macro to make this task automated.

Resharper 将突出显示解决方案中的所有此类错误，并单独修复它们，但我认为它无法通过单个命令修复所有这些错误。尽管如此，在它发现的错误之间导航还是很容易的。
Resharper will highlight all such errors in a solution, and fix them individually, but I don't think it can fix all of them with a single command. Still, it's easy enough to navigate between errors that it finds.
您可以在 emacs 中执行此操作。
打开您的文件 (
Cx Cf) 并执行Mx Replace-regexp。假设变量的名称是
Variable。您的正则表达式查询会将
\(V\)ariable替换为\,(downcase \1)ariable。\,告诉 emacs 下面的语句是一个 lisp 表达式。此外，如果您想同时替换 m_，您可以将
m_\(V\)ariable替换为\,(downcase \1)ariable。这将同时处理文件中的所有实例，并且 emacs 会记住您的最后一个替换正则表达式查询，因此您不必为多个文件重新键入它。此外，还有一种方法使用 DIRED 模式同时对多个文件进行替换正则表达式。
在 DIRED 模式下打开一个目录 (
Cx Cf DIR_NAME)，通过浏览标记您想要的文件（您可以使用n和p进行导航>) 按m。一旦标记了要处理的文件，请按Q（大写字母）。您将获得与执行单个文件相同的正则表达式提示，输入正则表达式、RET、替换内容和RET。它将一次打开每个文件，对每个文件按!来替换该文件中的所有 reg-exp。之后，您仍然需要保存文件。您可以使用
Cs然后使用!来完成此操作。You can do this in emacs.
Open your file (
C-x C-f) and doM-x replace-regexp.Let's say the name of the variable is
Variable.Your regexp query would replace
\(V\)ariablefor\,(downcase \1)ariable.The
\,tells emacs the following statement is a lisp expression.Additionally, if you wanted to replace the m_ at the same time you could do replace
m_\(V\)ariablefor\,(downcase \1)ariable.This will take care of all instances in a file at the same time and emacs does remember your last replace-regexp query so you do not have to retype it for multiple files. Furthermore, there is a way using DIRED mode to do the replace-regexp on multiple files at the same time.
Open up a directory on DIRED mode (
C-x C-f DIR_NAME), mark the files you want by going over them (you can navigate usingnandp) by pressingm. Once the files you want to process are marked pressQ(capital-case). You will get the same regexp prompt as if you did a single file, enter the regexp,RET, the replacement, andRET. It will open up each file at a time, press!for every file to replace all reg-exps in that file.After that, you still have to save the files. Which you can do with
C-sand then!.
