如何跳转到C / C ++函数声明而不是它的定义？

Question

I know CTRL+] to jump to definition of a function in various languages in vim. What about jump to declaration in C/C++ header?

Since I have plenty of headers containing meaningful comments/explanations, I would frequently find function declarations among a large code base. Is there some sorts of shortcuts to do this?

Answer 1

ctags does not add function prototypes by default. You have to add the option

--c++-kinds=+p

to support function prototypes. My ctags looks like this:

ctags --c++-kinds=+p --fields=+iaS --extra=+q *.h *.c

When you are at a tag, you can use the following editor commands to browser through the tags (Meaning the same tag occuring multiple times as definition/declaration)-

tn (Next Tag)

tp (Previous Tag)

Answer 2

I am satisfied with cscope, which includes header files in database.

Just put cscope_maps.vim in ~/.vim/plugin/ and then CTRL-] will list all choices if a cscope database is built.

To build a cscope database, just type

cscope -bR

Answer 3

Based on Bram's 7 habits , without any plugin, you can do

1) Set the path to your headers(This is crucial to work with point 2 below)

:set path+=/path/to/headers

2) Then do one of the following command

[I Display all list where keyword under cursor is in header files or

[<Tab> will jump there and you can come back to your file using Ctrl + 6
