Code fences inside a list render as one line

Bug
1

While testing another bug, I posted this text to try.discourse.org:

problem_post.txt (2.5 KB)

The editor preview shows line breaks in the code block, but the post itself renders without the line breaks.

This can happens when an invalid language keyword is used, let’s see

line above

size(600, 400);
println("width " + width);
println("height " + height);

versus

line above

size(600, 400);
println("width " + width);
println("height " + height);

line above
``` bleh
size(600, 400);
println("width " + width);
println("height " + height);
```

versus

line above
```
size(600, 400);
println("width " + width);
println("height " + height);
```

The code seems to work fine when it is not nested under a bullet.

  1. Some list

    size(100,100);
ellipse(x,y,100,100);

  2. Another list item

versus…

size(100,100);
ellipse(x,y,100,100);

It’s the backtick code blocks inside list which are not standardized across implementations (the preview and output differing seems like a real bug though). But you can use indented code blocks as a workaround until Discourse switches to markdown-it (which supports what you are trying to do).

1. first

        size(x, y);
        print(1);

2. second

        size(x, y);
        print(1);

3. third
4. and so on

  1. first

     size(x, y);
 print(1);

  2. second

     size(x, y);
 print(1);

  3. third

  4. and so on

Thanks I’ve fixed this in master (it’s currently being deployed):
