d2 VS dmd

While not embedded in markdown, I like d2 [1]. I can use it with org-babel to embed and view the diagrams on emacs. After using graphviz for years, the visual output seems more polished to me. With that said, I want to give pikchr a try.

In the next post I'll deep-dive into the D2 language which also has a huge set of features. Stay tuned.

That site is created by the maintainers of D2[1], so it might be biased, but I still think D2 has the friendliest syntax of the bunch, including nomnoml.

I've been using https://structurizr.com/ to automatically generate C4 diagrams from a model (rather than drawing them by hand). It works well with the approach for written documentation as proposed in https://arc42.org/. It's very easy to embed a C4 diagram into a markdown document.

The result is a set of documents and diagrams under version control that can be rendered using the structurizr documentation server (for interactive diagrams and indexed search).

I also use https://d2lang.com/ for declarative diagrams in addition to C4, e.g., sequence diagrams and https://adr.github.io/ for architectural decision records. These are also well integrated into structurizr.

Here's the pipeline spitting out the same error as on my macbook did.

Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo:

A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The reference compiler, DMD, is open source: https://github.com/dlang/dmd

But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md

However, by some accounts, it's really hard to get anything through.

Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
