v0.1.0
66f29c1

First release of Prismio: a compiled, statically typed language where the compiler decides how memory is managed. No garbage collector, no free, no lifetime annotations. The compiler is written in Prismio and builds itself to a byte-identical fixpoint.

Highlights

  • Smaller compiler: three LLVM backends (AArch64, X86, WebAssembly) instead of 25, about half the size.
  • Constant array globals: let words = ["alpha", "beta"] is read-only data.
  • print / println take anything printable, Option<T> included; std.term styles any printable value.
  • Shorter input: readLineOr, prompt, readInt, readFloat, readLines, readWords, isAtEnd.
  • Faster to compile: self-build IR emit 1.4 s to 0.7 s, identical output.
  • Fixed: a function ending in panic, unreachable or exit while owning a value emitted invalid IR.

Performance

On 62 workloads (Apple M5, 5 runs): geometric mean 0.87× of C++ and 0.84× of Rust, with peak memory level with C++ and 4% below Rust.

Install

macOS and Linux: curl -fsSL https://prismio.org/install.sh | sh
Windows: unpack the .zip and put bin on PATH.

Archives are named prismio-0.1.0-[os]-[arch] and each has a .sha256. They are not signed, so check the checksum from this page. You also need your platform's C tools to link programs (Xcode Command Line Tools, build-essential, or Visual Studio Build Tools).
