selo-pona

Two black sitelen pona characters in column, the top one is 'selo', the second one is 'pona'

selo pona (simple shell in toki pona) is an (planned) interactive shell and (planned) interpreted scripting language that is a (planned) superset of bash. That is, every bash script is also a selo pona script (planned), but selo pona adds some nicer syntax, on top. (planned)

Built in Rust, with minimal dependencies (for now, only libc, and leftpad)

Installation

You have to compile from source for now, some packages may be available when this project's out of pre-alpha someday.

Compiling from source

This project uses cargo. MSRV is 1.93. The only dependency you need is libc, it should work with either glibc or musl. File an issue if you find some discrepancy between them.

Clone the project, and run cargo build --release.
