write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • sounio_check

    Type-check a `.sio` source file and return structured diagnostics.

  • sounio_compile

    Compile a `.sio` source file.

  • sounio_runwrite action

    Compile and run a `.sio` source file, capturing stdout/stderr/exit code.

  • sounio_testwrite action

    Run Sounio tests and return per-test failures.

SOUNIO A self-hosted systems + scientific programming language for epistemic computing, uncertainty propagation, and algebraic effects

Website · Playground · Documentation · Manifesto · Examples · Status · Contributing

Sounio is a systems programming language for epistemic computing — its type system tracks not just what your data is, but how much you should trust it. Uncertainty propagation, provenance tracking, and confidence-gated execution are built into the type system, not bolted on as libraries.

Keywords: systems programming language, scientific computing language, epistemic types, uncertainty propagation, algebraic effects, self-hosted compiler, formal verification, non-associative algebra, octonions, e-graphs.

Technical Pillars & Core Keywords

The compiler is self-hosted: Sounio compiles itself, bootstrapped from a 2000-line C compiler through a multi-stage chain to a true fixed-point where stage N and stage N+1 produce bit-identical binaries. It was used to computationally verify a new result in algebra — that the count of nonzero octonion basis associators equals |PSL(2,7)| = 168 — now submitted for publication.

This is an active research project, not a production release. Read the honest status before using it for anything serious.

Cross-Repo Example: Cognitive O-SSM on SWOW-EN

The canonical Sounio checkout now includes a bounded cross-repo example under:

  • examples/cognitive_ossm/
