VIM: How to add custom markers before lines

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.

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.

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.

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.
