Markdown Discuss - Oct 2016 - Tab size of code blocks

Hi.

Markdown allows to include code blocks by using
```c
    printf("Hello World\n");
```

But it doesn't allow to specify the tab size (number of spaces). As I see,
Markdown states that the tab size is 4: "To produce a code block
in Markdown, simply indent every line of the block by at least 4 spaces
or 1 tab."

We use Markdown as a format for projects' wikis in gitlab. And we need
sometimes to include snippets of code to wiki pages. And lot of projects
use tab size of 8. It would be nice to allow to specify the tab size per
code block. For example (or with any other syntax):
```c;tab-size=8
    printf("Hello World\n");
```
(Or there could be some global setting at the start of the file.)

This would allow markdown to HTML converters to set the tab-size CSS
property properly. What you think?

Thank you.

Technically this syntax is an extension that is not part of the reference
Markdown spec. But it's true that many (most?) Markdown parsers support it
today.

You will have to check if the parser you are using has a setting like this. For
instance, there is one called [`tab_width`][1] in PHP Markdown. But note that
its effect will apply to everything in the document, not just code blocks, so be
cautious about using tabs to indent lists and other things if you change this
settings. Most likely, Gitlab uses another parser, so it it might behave
differently if it has such a setting.
