I'm more and more tempted by this kind of approach. Managing architecture models using code seems fairly neat. That said I wish we'd have better free software tooling for that, I find it still fairly limited. Maybe I should check out the Haskell library which is mentioned.

That looks like a nice declarative language to make diagrams. Missing sequence diagrams but otherwise seems fairly useful and readable.

A good list of tools for making diagrams in various situations.

Good collection of tools, I knew a couple but not all of them. Will go well with markdown uses or similar.
