Problem with codeblocks following lists #100
Comments
|
It's standard Markdown to expect a blank line between a list and any
other item. Same with code blocks. Don't be afraid of whitespace, it
makes it more readable even when it's not rendered.

Yeah, I discovered that the hard way :D Anyway, other markdown tools work with that kind of syntax, which makes mdless not render properly markdown files that are written like that ... But the scary thing is that mdless crashses on some conditions as explained above 😅 Example of that incorrect markdown rendering in github:

Mdless uses a specific markdown flavor. Markdown flavors vary pretty widely. But using standardized syntax works everywhere, e.g. adding a newline before and after block elements. That won’t break anywhere.
I can’t make a command line renderer work with every quirk of every Markdown flavor. Using responsible markup that offers the widest range of compatibility should be the writer’s goal.
Thanks,
Brett

I understand your point of view, but as a user, I want a tool I can use with files I did not produce. At least for me, it is the main use of mdless :) However, the big concern is not that something is rendered incorrectly, but that the app crashes, and thus nothing is rendered |

Assuming you’re using the 2.x series of mdless, the universality of the rendering is the best I can get it using the RedCarpet processor.
Thanks,
Brett

I'm not sure what the difference between "crashing" and not rendering
anything is. Do you receive an error?

Here is how it looks when it does not render the code block properly, but the file is processed anyway: And here is what happens when it crashes: |

can you attach the index.md file that this is failing on?
