HtmlLexer moved in Pygments 2.2.0

[tsvenson]

In: examples/full-screen/full-screen-demo.py

from pygments.lexers import HtmlLexer

Needs to be changed to:

from pygments.lexers.html import HtmlLexer

When using Pygments 2.2.0

PS: Haven't checked if this change happened in earlier version as I just installed latest version and stumbled on it.

@tsvenson,

I'm not sure this is correct.
Starting from a fresh docker container, it looks like this should work:

The thing that confused me was that in PyCharm, without .html then HtmlLexer was underlined in red with the error "Cannot find reference 'HtmlLexer' in '__init__.py'". It was also not possible to autocomplete it until I added .html.

I does work without for me too though.

That's because pygments uses a plugin system to load its lexers (even the built in ones), which is too dynamic for pycharm's completer to detect.

[tsvenson]

Thanks for the clarification @asmeurer, will report this to Jetbrains and see if it is something that can be addressed in PyCharm then.

Hi @tsvenson,

If you create a pull request, I don't mind merging that, if you think that's better. Otherwise, we can close this issue. Personally, I think the Pygments plugin system is too dynamic.

Hi @jonathanslenders,

Done. Even though it does work, this is better as it avoids the confusion I experienced while using PyCharm.

[asmeurer]

I spoke to some pycharm devs here at SciPy. Apparently if pygments stubs were added to https://github.com/python/typeshed it would fix the issue (pycharm uses typeshed).

@tsvenson: Can we close this issue?

[tsvenson]

@jonathanslenders: Of course. Thanks for letting me contribute!
