1.1.0 -> 1.1.1 breaks Python highlighting in Docusaurus

Hi,

Docusaurus (v2) uses this project for syntax highlighting.

https://v2.docusaurus.io/docs/theme-classic/#codeblock

Let’s take this code:

@dataclass
class MySQLConfig:
    host: str = "localhost"
    port: int = 3306

@dataclass
class Config:
    db: MySQLConfig = MySQLConfig()
    verbose: bool = True

cfg_store = ConfigStore.instance()
cfg_store.store(name="config", node=MyConfig)

@hydra.main(config_name="config")
def my_app(cfg: MyConfig) -> None:
    # Python knows that the type of cfg.db is MySQLConfig without any additional hints
    print(f"Host: {cfg.db.host}, port: {cfg.db.port}")

if __name__ == "__main__":
    my_app()

When using:

  "resolutions": {
    "prism-react-renderer": "1.1.0"
  },

Python highlighting works fine for this code:

But when using newest version, highlighting is missing for things like decorators (or applied partially):

  "resolutions": {
    "prism-react-renderer": "1.1.1"
  },

@kitten as you proposed your help already here: https://github.com/facebook/docusaurus/pull/2666#issuecomment-619602671 wonder if you can help me figure out what’s happening.

The code does not seems to change much from 1.1.0 to 1.1.1 so I don’t understand.

Anything I don’t see in the commits?

Do you think this might affect other languages as Python, and that we should temporarily lock users to 1.1.0?

Hm, that’s odd, it should indeed still be 1.20.0. I may have to look into this a little further

Thanks.

How can I know which version is currently vendored in this lib?

The package says "prismjs": "^1.20.0", and it does seem to have changed, and it’s the latest version of Prism anyway. Is this the version vendored here?

Here’s a PR that fixes a Docusaurus site: https://github.com/facebookresearch/hydra/pull/730/files#diff-133739a86bc2f5157391e0018e5f9d01R7409

The yarn lock versions of prism is still the same before/after
