Examples

The Rhyme test suite explores a number of use cases with helpful examples:

• Test Suite Entry Point (test/)
  • Advent of Code (aoc/):
    • AOC 2023 (aoc_2023.test.js): full implementation of the 2023 advent of code challenges
  • C generation (cgen/) generating C code for sparse tensors and SQL-style workloads
  • JSONBench (json-bench/) the five queries of JSONBench over a stream of Bluesky events in NDJSON form, compiled to C
  • Miscellaneous (original/)
    • Grouping (grouping.test.js) demontrate various forms of grouping
    • Sorting (sorting.test.js) demontrate how to implement sorting using UDFs
    • Recursion (recursion.test.js) demontrate how to implement recursion using an external driver loop
    • Tensors (tensors.test.js) demonstrate various matrix and tensor operations, including batched matrix products
  • Semantics (semantics/)
    • Custom data structures (se-datastruct.test.js) demontrate how to use custom datastructures (red black trees, typed arrays, sparse and dense tensors)
    • Recursion (se-recursion.test.js) demontrate how to implement recursion using an external driver loop (additional tests)
    • Tree paths (se-tree-paths.test.js) demonstrate shape polymorphism using tree-path variables
  • TPC-H (tpch/) all 22 TPC-H queries expressed in Rhyme and compiled to C, using typed schemas for the CSV input tables (plus alternative formulations of q1 and q17)
  • Typing (typing/) demonstrate experimental typing facility

Interactive Demos

In addition, there are a number of interactive examples for running Rhyme in the browser:
