Lost nothing in translation.
Useful libraries, each ported to the languages it's needed in: Swift, Go, Python, Kotlin, Rust, Nim, Zig and Julia. The first ports are in Swift, Nim, Zig and Julia, with Go and Python next.
The goal is to take on a whole project in one language, or try the same one in a different language just for fun.
Each library is written down once, as a spec with shared test cases, and every port passes the same cases. Each port aims to read like it was written natively in its language, not translated word for word, and credits the format or project it implements.
| Library | Swift | Go | Python | Kotlin | Rust | Nim | Zig | Julia |
|---|---|---|---|---|---|---|---|---|
| Polyline: Google's encoded polyline format | polyline-nim v0.1.0 |
polyline-zig v0.1.0 |
EncodedPolyline.jl (registering) |
|||||
| PMTiles: read PMTiles v3 tile archives | pmtiles-swift 0.2.0 |
pmtiles-nim v0.2.0 |
pmtiles-zig v0.2.0 |
|||||
| robots.txt: RFC 9309 parsing and matching | robotstxt-swift 0.1.0 |
robotstxt-zig v0.1.0 |
RobotsTxt.jl (registering) |
Install instructions and examples for every port are at docs.xenoglyphiq.dev.
Each library has a spec repo, <lib>-spec, and one repo per language, <lib>-<language>
(Julia: <Lib>.jl). For example, PMTiles is pmtiles-spec, pmtiles-swift, pmtiles-nim
and pmtiles-zig. Package names follow each language's own conventions; see
NAMING.md.
