Use case or problem
Users have need to add various container based blocks into their article.
An extensive syntax called admonition did a adequate effect, it’s syntax is like that:
!!! note "Jaycee Chow's diary"
Today is a sunny day.
??? note
This is collapsed by default.
!!! abstract
Long long time ago, ......
A existing obsidian plugin provide such syntax:
```admonition-note
The note message
```
But, in a normal Markdown editor, the above syntax don’t have a good downward compatibility.
In the meantime, many users do have urge need of a way to create admonition or other container based blocks.
Proposed solution
The quote syntax is naturally a container syntax of Markdown, a suggested solution is to introduce a quote syntax based extension syntax, for example:
> [info] Alice's *reminder*
>
> Don't forget to take the garbage before going outside.
> [warning] ==Warning Title==
>
> This is a warning admonition block.
> [danger] A danger reminder
>
> > [info] note
> >
> > Indent note
> [info|hide] The message below is **collapsed**.
>
> This part is collapsed by default, because of the 'hide' keyword. But you can unfold it.
> [note|center] A poem
>
> 床前明月光，
> 疑是地上霜。
> 举头望明月，
> 低头思故乡。
>
> (This part is ought to be center-aligned, a better way to show a poem)
> [box|red] This part should be within a red box frame
>
> It can highlight some important paragraphs.
The preview of the above could look like that:
A great advantage of this syntax is that it have a great downward compatibility to normal Markdown Editor. Even if your editor don’t have special support of this syntax, it still can show the message as a quote block, just less colors and styles:
[info] Alice’s reminder
Don’t forget to take the garbage before going outside.
[warning] ==Warning Title==
This is a warning admonition block.
[danger] A danger reminder
[info] note
Indent note
[info|hide] The message below is collapsed.
This part is collapsed by default, because of the ‘hide’ keyword. But you can unfold it.
[note|center] A poem
床前明月光，
疑是地上霜。
举头望明月，
低头思故乡。(This part is ought to be center-aligned, a better way to show a poem)
[box|red] This part should be within a red box frame
It can highlight some important paragraphs.
See, all the indent, container, inline style were all kept (just less colorful styles). Even if in a plaintext editor, you can easily tell that part is in a container block.
At the end
This topic is meant to open a discussion of this new syntax, details of it’s implementation ought to be explored. I think it’s pretty innovative.
