   Generate diagrams from textual description

   

   I have used Plant UML a lot and I love it. Anything that can help me draw less figures is a bonus and the markup language they use is pretty flexible and ergonomic.

   However, I have one major gripe with Plant UML. About 3-4 years ago, my local install started showing memorial plaques for people who died in a terrorist attack in Paris [1]. While this attack was undoubtedly a horrible event, I still feel it is deeply unprofessional to include stuff like that in a program, and it makes me lose all trust in the developers. If they had just added a memorial section in the program, it would have been fine. However, for every error generating a diagram, Plant UML would show a popup window with a picture and a text in memory of that person.

   This is similar to what the Notepad++ developer(s) did back in 2013-ish where they had a memorial build into a new release of the program. On startup, Notepad++ would write (literally type it out) some message into the default empty document [2].

   It might be a bit harsh. But in my mind, if the developers of these programs can be so influenced as to push this onto their unsuspecting users, I feel they have misused my trust. It makes me think: "What are they going to put into it next? Malware? Perhaps watermark the output with a statement?"

   Since these events, I have avoided Notepad++ entirely and been reluctant to use Plant UML, but used it out of necessity.

   Generate PlantUML ER diagram textual description from PostgreSQL tables

   

   I use Plant UML in combination with planter [1] to auto-generate a DB schema during CI runs.

   Recently I see a lot general statements on HN like "UML is dead" which I think is not the case. Especially in complex, data-heavy projects it's a great way to visualize how things work -- if kept up-to-date and precise.

   Generation of diagrams like flowcharts or sequence diagrams from text in a similar manner as markdown

   

   Huge fan of the Javascript equivalent, although not as featureful: https://mermaid-js.github.io/mermaid/#/

   Gitlab has support for it built-in, and so do many Markdown editors (https://marknoteapp.com/).
