Command T is a Vim Plugin that is Ruby based. It enables to make a fuzzy search for files and in files.

To The Point


To install Command_T you need to have ruby addons in vim.

Check out if you have ruby-support in vim with vim command:

:ruby 1

If you are so lucky as I am and you have following output:

E319: Sorry, the command is not available in this version

Than you have to add ruby-support to your vim or install vim with pre-existing ruby support.

Installing Vim with Ruby support

If you use Ubuntu system, you can install vim with ruby support with:

sudo apt-get install -y vim-nox;

For other, I'd suggest to build vim with commands shown in this stackoverflow answer:

git clone vim
cd vim
./configure --enable-rubyinterp
sudo make install

Installing vim-plugin.

After enabling ruby support in vim, you need to add this to your vimrc using Vundle :

Plugin 'wincent/command-t'


To use you can invoke it with <Leader>t - so the \t standard vim combination.

Well ... My first usage outputed with this beautiful error:

command-t.vim could not load the C extension.
Please see INSTALLATION and TROUBLE-SHOOTING in the help.
Vim Ruby version: 1.9.3-p484
Expected version: [unknown]-p[unknown]
For more information type:    :help command-t

What it means? it means that we need C extension for the plugin to work properly.

The documentation with this installation guide gives information that we should go to vim-plugin folder:

cd ~/.vim/bundle/command-t/ruby/command-t/ext/command-t

And compile extension with:

ruby extconf.rb 

But my system does not have all ruby-extensions and building tools, so it failed with:

Unable to require "mkmf"; you may need to install Ruby development tools
(depending on your system, a "ruby-dev"/"ruby-devel" package or similar).

Let's install them:

sudo apt-get install -y ruby-dev

And now checking again compilation goes with this effect:

ruby extconf.rb 
checking for float.h... yes
checking for ruby.h... yes
checking for stdlib.h... yes
checking for string.h... yes
checking for fcntl.h... yes
checking for stdint.h... yes
checking for sys/errno.h... yes
checking for sys/socket.h... yes
checking for ruby/st.h... yes
checking for st.h... yes
checking for pthread_create() in -lpthread... yes
creating Makefile

Now let's make this.:


Outputs with:

compiling heap.c
compiling ext.c
compiling matcher.c
compiling match.c
compiling watchman.c
linking shared-object

So it means we are good to go ?

Checking... Yeah!! It works.



sudo apt-get install -y vim-nox;
sudo apt-get install -y ruby-dev;


Plugin 'wincent/command-t'

Building plugin:

cd ~/.vim/bundle/command-t/ruby/command-t/ext/command-t
ruby extconf.rb
