问题
I want to mark erroneous lines a source code. I detect the incorrect lines using an external program (e.g., flake8). When I save the source, I would like VIM to execute the external program and mark invalid lines.
I thought about different possibilities of "marking" the lines, like underlining full line or changing background colour. What I would like to do is to have an additional column on the left hand side of the text, where I could place some markers (e.g., ">") indicating the offending lines.
I know about the flake8 vim plugin, it displays full flask output and I want just small markers.
Question:
How can I add such a "special column"?
I thought about a separate window with width=1, but maybe there are better options.

回答1:
for your requirement, I suggest syntastic plugin, like others.
for your question, "add a customer marker before lines/special column" you should take a look sign.
:h sign
has more details, with examples.
Many plugins (syntastic, showmarkers....) have used this feature. you could add your own text, highlight and so on for your own sign.
回答2:
Take a look at the sources of the Syntastic plugin. Maybe you don't even have to write your own plugin, but can leverage Syntastic's powers.
回答3:
Did you try Syntastic? It does everything you want and more.
The column you speak of is the "sign column", you can read all about it in :h signs.
