在 Vim 中，文件名的制表符补全不起作用

Question

When I try to open a file in Vim (Linux) for editing, when I press TAB, Vim autocompletes filename only with filenames from the current directory. However, having searched on the Web, I suppose that from version 7 Vim should support bash-like filename autocompletion using filenames from all the directories in the search path.

Say, there is a file file1 in a directory dir1 (which directory is also in the environment variable PATH).

I type the following commands in Vim:

set path=/dir1
set wildmode=list:longest

And then, when I type:

:e fil<TAB>

The filename is not autocompleted. How to enable this feature in Vim?

Answer 1

Tab-completion works. You just expect it to do something it is not actually supposed to do.

:e[dit] and its siblings ( :sp[lit] , :vs[plit] , :tabe[dit] ) don't use the path option at all, no matter what version of Vim you have.

• Use :fin[d] fil<Tab> instead (and :sf[ind] , :vert sf[ind] , :tabf[ind] ).

• Use set path=/dir1/** to make :find recursive.

See :help 'path' and :help :find .

It is generally considered "good practice" to start Vim from the root of your project:

$ cd /path/to/project
$ vim somefile

The main advantage being that it sets Vim's "current directory" to a usable value that allows you to browse your project relatively easily or use external programs on your project in a clean and intuitive way.
