Support parsing ```plantuml code block in markdown

[chuxubank]

vscode-plantuml gives a way to preview plantuml in markdown in vscode. See here

It will be a nice thing to support this feature because there is no need to delete ```plantuml ... ``` when deploy a site.

Thanks for creating an issue! I am really busy right now. I will have a look at this in a week or so.

Markdown uses ``` to display source code. To me, it is really weird how that plugin uses ``` to actually run the code. After a bit of though, I am not going to integrate this in the library, sorry =(

Actually not only vscode-plantuml run the code, in Typora many other diagram plugins also run the code lol, such as Sequence, Flowchart and Mermaid. See here

Ohhh it's a pity! Also Gitlab uses this behaviour: https://docs.gitlab.com/ce/administration/integration/plantuml.html

Yes indeed, please reopen this issue. This syntax is much more clean and compatible with other markdown parsers.

Agree, for sake of consistency with other markdown parsers, please consider reopening this issue.

I ended up writing some custom code to use fenced blocks

```plantuml

as markers. The source code of this plugin was helpful to understand how Markdown-it plugins work, so thanks to the original author.

I use this config:

const config = {
  openMarker: '```plantuml',
  closeMarker: '```'
}

I'd also rather see the fenced version as default, as this allows indentation (which can be very helpful). Anyway regular markdown would treat indentation as code blocks.

@gossi This config conflict with hexo's built-in highlighter. Maybe it's not possible to use code blocks for rendering in hexo
