I use a text to diagram tool called PlantUML. It’s perfect! Now, I want to use it with my hugo site, through a short code. So, I I type a code like below, I should see out like as the image.
A -> B : Hello
Update: I spend many hours trying to work this out. Created a firebase function to process posting and converting and yada yada. But finally gave up on Hugo. Until there is a plugin support in the core, this will be a very challenging thing.
