#ReleaseWednesday — Extracted & extended the LISP-like DSL from an existing #ThingUmbrella example[1] as new small package for better/direct re-use in other projects:
The core language is kept intentionally minimal, aimed at simple sandboxed data transformations/derivations, small code snippets/expressions in GUIs or config settings. However, the language is very easy to extend/customize with new functions or control flow constructs etc. Currently, the language is interpreted and has the following builtins (see screenshots). There's no macro support so far (and not sure if that's even desired here)...
[1] The original #HowToThing example browser REPL this was extracted from (and which has now been updated to use the new package):
