julia> str = md"""
hi
```
1 + 1

""";
then display will print the markdown string in a nice way:

but print and show and friends all fail to do it:

Is there a way to do this without display? I need to specify a specific output stream, which you can't do with display.
Mason Protter (Feb 27 2024 at 13:45):cc @Timothy since I suspect you're the expert on this
Fredrik Ekre (Feb 27 2024 at 13:50):Markdown.term I think?
Timothy (Feb 27 2024 at 14:01):Yep! Markdown.term(::IO, ::Markdown.MD) is what you want.
Mason Protter (Feb 27 2024 at 14:02):ah cool. It'd be good if this was documented then
Timothy (Feb 27 2024 at 14:02):Yea. Reminds me, I really should get a move on with checkdoc...
Mason Protter (Feb 27 2024 at 14:03):in particular, does Markdown.term fail gracefully if io doesn't support fancy outputs?
Sebastian Pfitzner (Feb 27 2024 at 14:04):actually, why is that the bevhaviour of show for markdown objects? seems like the show method should check the output streams capabilities (just color is probably enough), no?
Timothy (Feb 27 2024 at 14:04):in particular, does Markdown.term fail gracefully if io doesn't support fancy outputs?
Yes
Mason Protter (Feb 27 2024 at 14:04):very annoying, since show is supposed to be the function that does that
Timothy (Feb 27 2024 at 14:05):IMO it should behave like you expect
Mason Protter (Feb 27 2024 at 14:15):In any case, thanks both of you!

It's nice to have markdown formatting for register_error_hint.
Timothy (Feb 27 2024 at 15:13):I was curious :)
Timothy (Feb 27 2024 at 15:14):I think that use of Experimental API isn't quite right though IIRC
Timothy (Feb 27 2024 at 15:15):I think the version check should be replaced with a isdefined(Base.Experimental, :register_error_hint) check
Mason Protter (Feb 27 2024 at 15:16):The version check was there because I was trying to avoid a failure on 1.6. The original PR did the isdefined but then it turned out the failure was something else, so I've now switched it back.
Mason Protter (Feb 27 2024 at 15:19):By the way Timothy, since you're looking at it, do you have thoughts on the hint itself? I know you advocated in your manifesto-in-progress for using error codes so people can look up more elaborate descriptions of errors, do you think this is case that'd be better off with an error code or documentation link?
Timothy (Feb 27 2024 at 15:20):I feel like much of the benefit with error codes is when they're a standard/ubiquitous system. I'm looking forward to that day, but until we get there I think your current approach is probably the best option. My 2c.
Timothy (Feb 27 2024 at 15:20):As an aside, I love to see the effort you've gone to in creating a properly helpful error message there :heart:
Mason Protter (Feb 27 2024 at 15:34):Well I did it because I was thinking of your document
