Vim关键字完成

Question

如何告诉Vim编辑器我的包含文件路径,以便在按CTRL+ 时它可以自动完成功能名称N？

例如,我有一个如下的C程序:

#include<stdio.h>
int main()
{
    sca // here I press control+N, it does not complete to scanf
}

Answer 1

在你的.vimrc,添加路径.vimrc:

set path+=/usr/include/**
set path+=/my_include_dir/include
set path+=/my_include_dir/srclib/apr/**
set path+=/my_other_include_dir/srclib/apr-util/**

** means all sub-directories.
*  means all contained directories
.  means all files in the directory of the found file
+= means prepend to existing path (iirc)

您也可以通过打开文件然后输入来检查路径

:checkpath

这将为您提供缺少的所有包含文件的列表.注意它似乎没有处理预处理器指令,所以你会得到一些误报.进入

:checkpath!

将提供已找到和缺失的包含文件的完整列表.

此外,重要的是要注意有许多完成功能.

^x ^o  = "omnicomplete" 
^x ^i  = "included-files completion" 
^x ^f  = "path completion" 
^x ^l  = "Complete this line using one that looks the same"
