Show HN: Larksson-lang: everything is a map or an atom
Larksson-lang is a new homoiconic programming language where programs and data share the same structure. It operates on two types of values: integers and maps, eliminating the distinction between expressions and data. The language allows for dynamic program construction and execution by treating everything as a map.
- ▪Larksson-lang treats programs and data as the same entity, utilizing a homoiconic structure.
- ▪It features only two types of values: integers and maps, simplifying the programming model.
- ▪The language allows for runtime program construction and execution by using maps.

<name, formerly larksson> A small homoiconic language: programs and data have the same shape because they are the same thing. lines! .ops.add. = { args: { left: 2, right: 3 }, return: 0, trigger: 0 } .var.sum. = (.ops.add.return.) That runs 2 + 3, stores 5 in .var.sum., and dumps the final state of root. Three things to notice: add is a value with a particular shape, the assignment to a key called trigger is what causes computation to happen, and the result is read back through a path. Every operation works this way. The conceit There are exactly two kinds of values: integers and maps. Strings are maps from indices to character codes. Arrays are maps from indices to their elements. Paths are maps from indices to their components. Programs are maps from indices to statements.
