Extension broken with Markdown 3

[ntarocco]

I am using the extension but with the release of Markdown 3.0.0 and 3.0.1 the extension is broken. I didn't have time to look into the code. For now, I have pinned to Markdown<3 and everything works.

I've tested v1.2.5 of the plugin with Python 3.5.5 and Markdown 3.0.1 and seems to work without problems. Can you post a log trace and a simple markdown test to be able to reproduce your error? And, what version of Python are you using?

[ntarocco]

I am sorry, the problem apparently comes from mkdocs and not from this package. Sorry for the noise, I close the issue.

Actually, I am doing further tests, the problem happens loading plantuml.py (I am using mkdocs).

Environment:

• Python 2.7
• Markdown==3.0.1
• pymdown-extensions==5.0

While, downgrading Markdown, everything works. Does it help?

[mikitex70]

I'm unable reproduce your problem. My test steps:

# Create a test environment
mkdir /tmp/test
cd /tmp/test
python2 -m virtualenv env
. env/bin/activate
# installing required packages
pip install mkdocs==1.0.4 markdown==3.0.1 plantuml-markdown==1.2.5 pymdown-extensions==5.0
mkdocs new testsite
cd testsite
# Activating plantuml markdown extension
cat >>mkdocs.yml <<EOF
markdown_extensions:
    - plantuml
EOF
# Adding a simple diagram to index page
cat >>docs/index.md <<'EOF'

```plantuml
a -> b

EOF

Starting server

mkdocs serve

and the diagram was correctly rendered.
I'm missing something?

Thank you @mikitex70 for the example, it actually works. So, I was not using directly the extension via pip install, but using the second method explained in your readme (old tests) that was copying the file. Well it should be the same, but it stopped working with the release of Markdown... I don't have a clear explanation, sorry. Now I switched to pip install everything, and it works perfectly.

Thank you for trying it out!
