Vim c++ 区分同名符号的索引

[英]Vim c++ indexing that differentiates between symbols with same names

原文 2022-06-01 17:36:49 6 1 vim/ tags/ ctags/ cscope

I've been trying out vim with exuberant tags and cscope but when listing the usages of a variable it also lists variables with the same name that aren't really the symbol I'm looking at.我一直在尝试使用 vim 和 exuberant 标签和 cscope，但是在列出变量的用法时，它还会列出具有相同名称的变量，这些变量并不是我正在查看的符号。 For example if I want to jump to the declaration or other usages of a variable called "temp", it will give me all variables called "temp" in the whole repo.例如，如果我想跳转到名为“temp”的变量的声明或其他用法，它将给我整个仓库中所有名为“temp”的变量。 Am I using tags and cscope wrong or is there another plugin I should be using instead?我使用的标签和 cscope 是错误的还是我应该使用另一个插件？

1 个解决方案

Ctags and cscope use parsers and even regular expressions to find symbols in files. Ctags 和 cscope 使用解析器甚至正则表达式来查找文件中的符号。 They "understand" syntax, in a way, but they don't understand code so they have no idea about what specific function is called where.他们在某种程度上“理解”语法，但他们不理解代码，因此他们不知道具体的 function 在哪里被调用。

Consequently…最后…

that relationship is not encoded in the resulting database,该关系未编码在生成的数据库中，
and it is lost to any program using ctags or cscope.并且它会丢失给任何使用 ctags 或 cscope 的程序。

If you want a tool that knows exactly which temp is referenced, then you don't want csope or ctags.如果您想要一个准确知道引用了哪个temp的工具，那么您不需要 csope 或 ctags。 You want something based on a compiler, like clang.你想要一些基于编译器的东西，比如 clang。
