Coming to CommonMark from Github Markdown we desperately miss multiline image URLs for e.g. embedding PlantUML diagrams in our documentation. Here’s an example:
!(http://plantuml.rado0x54.com/png?uml= @startuml Hans -> John : Hallo John -> Carla : Hi Carla -> Hans : Ola @enduml )
This worked on Github and still works in some markdown editors like MacDown and it would be great to have it back. All additional lines within the brackets are just URL-escaped on the fly leading to the following code for the example above:
The original allows our diagrams to be edited in place and having diagrams as first class citizens in our documentation was a huge win to using external tools as we did before…
What’s your opinion? Does it hurt to add that to CommonMark?
