https://peertube.watch/videos/watch/172ea99d-e239-4e18-8602-44f6fa2a0cb9 calculang is a language for calculations, pure-functional and portable in concept, currently compiling to Javascript. In this talk I'll show some examples that demonstrate language design principles: input inference, modularity and specific features:, inheritance of parent functions and overriding, These work together so that calculang functions (or 'formulae') are flexible, concise and understandable, and maintainable. I will also demo calcuvizspec, a declarative visualization API for calculang models based on vega-lite. calculang and calcuvizspec are free software. calculang is currently available on GitHub. Updates @calculang on Fosstodon. Slides: link calcuvizspec Visualization API based on Vega-Lite presentation: link (but, calculang is non-opinionated!)
