Install and setup vim on Ubuntu 14.04

This post is more than 5 years old. While math doesn't age, code and operating systems do. Please use the code/ideas with caution and expect some issues due to the age of the content. I am keeping these posts up for archival purposes because I still find them useful for reference, even when they are out of date!
Vim is a powerful editor that can be used on your laptop/desktop and is also typically found on any Linux server you might encounter. As a result, I started using vim as my main editor. The Ubuntu install is simple:
$ sudo apt-get install vim
My next step is to add a variety of vim plugins that make (my) life easier. To do this I use pathogen a wonderful vim package manager. Installation is accomplished with the following lines:
$ mkdir -p ~/.vim/autoload ~/.vim/bundle;
$ curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim
If you don't have curl installed, use:
$ sudo apt-get install curl
and try the second line again. Finally, if you don't have a
~/.vimrc file create the following minimal
" contents of minimal .vimrc
filetype plugin indent on
NERDTree is a plugin the provides a nice file browser with bookmarks. With pathogen available, getting NERDTree installed is as simple as:
$ cd ~/.vim/bundle
$ git clone https://github.com/scrooloose/nerdtree.git
After installing, start vim and type::
to toggle the file browser open or closed. Use up and down arrows to select
files and press
enter to open file in current tab. To open in
a new tab, select the file and press
To bookmark, select a directory and type
to assign bookmarkname to the desired directory. To toggle
the bookmarks open or closed (while in the NERDTree window)
shift-b. Finally, to open a bookmark,
select the bookmark using up/down arrows and press
enter when the desired bookmark is
Tagbar does a nice job of showing code outlines-- class, methods, etc and allows for jumping to different parts of the code using the outline. I've mainly used this with Python, where the results are very nice.
First, we have to install exhuberant ctags , which Tagbar uses to do its parsing. Luckily, there is version in the Ubuntu repository:
$ sudo apt-get install exuberant-ctags
Next, install the vim plugin using pathogen, as before:
$ cd ~/.vim/bundle
$ git clone git://github.com/majutsushi/tagbar
Thanks to pathogen, we can now start vim and type::
to toggle the code outline open or closed. To get to the code outline window
Cntrl-w and then
l -- this is a general vim
command to move to the right window. Use up and down arrows
to move through the code outline. When the desired class or function is
enter and vim will
jump to the desired code. This is very nice for larger files!
$ pip install --user jedi
I use this command assuming that you are installing all python packages as a user. Otherwise you will have install with
# global install
$ sudo pip install jedi
# or, activate virtual environment and use
$ pip install jedi
Finally, use pathogen to install jedi-vim in the usual way:
$ cd ~/.vim/bundle/
$ git clone https://github.com/davidhalter/jedi-vim.git
The two command I use most with jedi are:
shift-k: get documentation (must be in command-mode and put cursor on function of class of interest)
vim-template is a plugin that provides nice file templates for new files. Using pathogen the installation is simple:
$ cd ~/.vim/bundle
$ git clone git://github.com/aperezdc/vim-template.git
$ vim test.py
$ vim test.sh
to see the standard templates for Python files and bash scripts, respectively.
There are a variety of customizations that can be made (see the link above),
but I like to add the following defaults to my
" Customize the settings for vim-template plugin
let g:email = "email@example.com"
let g:user = "Desired Name"
let g:license = "Desired License"
That's it for my basic vim and vim-plugins setup. Questions and comments are always welcome.
