Jun 2025 (v0.6.2)

Mochi v0.6.2 expands the foreign function interface and adds more data loading options.

Foreign Function Interface​

Programs can import modules from Go, Python and TypeScript and call them through new FFI runtimes. A Deno runtime enables TypeScript interoperability.

import go "math" as math
import python "polars" as pl

extern fun math.Sqrt(x: float): float
extern fun pl.col(name: string): any

Dataset Loaders​

load now supports JSON and YAML files in addition to CSV.

let people = load "people.yaml" as Person

Other Changes​

  • FFI code moved to runtime/ffi
  • Fixed notebook magic path and TypeScript import tests
