Good feedback, thanks!
> PostScript is both a general-purpose and domain-specific programming language. Can you make that consideration?
Ah you are right, the current categorization as a textMarkup isn't quite a great fit and the ontology in PLDB can be improved. I'm linking your comment to a related issue that I hope to address this week. https://github.com/breck7/pldb/issues/39
Some programming languages that have semantic indentation allow to turn off that feature, such as Haskell. Other more complex considerations than only has or not has, also is relevant for other features of other programming languages, too.
Some programming languages are domain-specific and might only be used in specific programs because it is a narrow enough use, e.g. ZZT, MegaZeux, and Free Hero Mesh; do any of those count? (ZZT is rather limited, but the other two aren't so limited.)
Other features of programming languages to be considered:
- Character encodings
- GOSUB
- Byte arrays
- Generalized algebraic data types
- Sigils
There is also consideration of variants of programming languages.
