我正在阅读xl2tpd的源代码,并在阅读此代码时遇到很多问题.例如,我找不到结构lac的定义.我如何找到这个结构的定义？
我使用ctags和vim来读取此代码,但未能找到结构.我用Google搜索,找不到结构.有没有什么方法可以让代码阅读过程更舒服？也就是说,我可以跳到大多数变量,函数和结构的定义？
解决方法
用vim试试cscope.按照以下步骤 –
1)在xl2tpd目录中运行cscope -R.它将创建文件cscope.out
2)使用vim打开文件,其中使用结构lac
3)使用：cs f g< lac> .现在它将显示定义lac的文件.
4)选择file.h.它包含定义.
如果您对struct lac的定义非常感兴趣,那么它是 –
