Powerline is a statusline plugin for vim, and provides statuslines and prompts for several other applications, including zsh, bash, tmux, IPython, Awesome and Qtile.
Equivalent to airline csv Christian Brabandt plugin integration, but uses Python
own facilities.
Note: filetype detection is out of the scope of the powerline responsibilities.
CSV is supported by powerline, but only as long as filetype detection is
done by Vim correctly. By default CSV files are neither detected nor
highlighted.
Some known differences between powerline code and @chrisbra plugin with
corresponding airline integration:
1. Detection work differently. I cannot say which is better because I have not
tested it much, but it is definitely different.
2. My variant is able to detect whether there is (no) header. (Of course,
relying on Python code.) Airline is using a setting. (Both do not allow
manual per-filetype setting.) Of course, user can force either variant (no
headers at all or headers always).
3. My variant makes it possible to configure header output format, including
truncating it at 15 characters (the default).
4. CSV plugin does not work with multiline CSV items (in some dialects one can
use code like `abc;"I<CR>am<CR>multiline<CR>string"`). See `:h csv-column` on
how to fix this if possible (will require also changing `<sid>WColumn`
function because currently it only works with one line).
5. AFAIK Python does not such a thing as “fixed width CSV”. Thus I do not work
with this, but CSV plugin does. Not sure whether it is different with
space-separated CSV files though.
This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

Features
--------
* **Extensible and feature rich, written in Python.** Powerline was
completely rewritten in Python to get rid of as much vimscript as
possible. This has allowed much better extensibility, leaner and better
config files, and a structured, object-oriented codebase with no mandatory
third-party dependencies other than a Python interpreter.
* **Stable and testable code base.** Using Python has allowed unit testing
of all the project code. The code is tested to work in Python 2.6+ and
Python 3.
* **Support for prompts and statuslines in many applications.** Originally
created exclusively for vim statuslines, the project has evolved to
provide statuslines in tmux and several WMs, and prompts for shells like
bash/zsh and other applications. It’s simple to write renderers for any
other applications that Powerline doesn’t yet support.
* **Configuration and colorschemes written in JSON.** JSON is
a standardized, simple and easy to use file format that allows for easy
user configuration across all of Powerline’s supported applications.
* **Fast and lightweight, with daemon support for even better performance.**
Although the code base spans a couple of thousand lines of code with no
goal of “less than X lines of code”, the main focus is on good performance
and as little code as possible while still providing a rich set of
features. The new daemon also ensures that only one Python instance is
launched for prompts and statuslines, which provides excellent
performance.
*But I hate Python / I don’t need shell prompts / this is just too much
hassle for me / what happened to the original vim-powerline project / …*
You should check out some of the Powerline derivatives. The most lightweight
and feature-rich alternative is currently Bailey Ling’s `vim-airline
<https://github.com/bling/vim-airline>`_ project.
