How to correctly convert code blocks with newlines?

[leakec]

Hello,

I'm having trouble correctly converting the following code block, i.e., with a newline at the beginning and the end:

```

code-block

```

I'm trying to do this conversion using

python -m markdown test.md -x pymdownx.extra

where test.md contains the code block above.

If I run it using a code block without spaces, i.e.,

```
code-block
```

everything runs correctly. Alternatively, if I downgrade pymdown-extensions to version 9.2, the code block with newlines runs correctly. Is this a bug, or is there something I need to do in version 9.4 to get code blocks with newlines to convert correctly?

Thanks,
Carl

I'm not sure why you are having issues. So I checked out the latest tag (9.4). Dropped your markdown into a test.md file, and this is what I got:

➜  pymdown-extensions git:(72390ce2) ✗ python3 -m markdown -x pymdownx.extra example.md
<div class="highlight"><pre><span></span><code>code-block
</code></pre></div>%

Can you elaborate on what you mean my it isn't working correctly?

Hmm. Maybe update Pygments? It's the only other thing I can think may be giving you trouble.

I'm not sure which package was the offending one, but updating everything via:

pip list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

did the trick. Now everything woks with version 9.4 and 9.2 :)

Thanks for all the help!

You're right pygments was it. I tried downgrading to the one I originally had (2.7.4), and the issue popped up again. Upgrading it to 2.12.0 fixes it!

Okay, that makes sense. Pygments made a change to their formatting very recently. Pymdown Extensions had to accommodate it properly in the most recent version. Sorry I didn't put 2 + 2 together on that one earlier 🙃.

No worries; I'm glad you found it, since there a few more computers this will be used on that will need to update pygments as well.
