Rust Playground for MacOS

status: experimental / pre-release / guaranteed buggy

The Rust Playground for MacOS is a standalone native mac application that allows quickly editing and testing rust snippets.

installation

You can download a disk image of a recent build on the releases page.

requirements

The playground requires rustup, and allows code to be run with any installed toolchain. note: Rustup must currently be in the default directory, $HOME/.rustup.

install from source (requires Xcode)

clone this repository
cd in to the RustPlayground directory
run xcodebuild from the command line
copy build/Release/Rust Playground.app to your Applications directory

About

This project is based on a fork of the xi-editor core. It is intended largely as an experimental offshoot of xi; a narrowly scoped editor frontend that can be used to experiment with various design decisions.

Document state is handled in rust; the swift frontend interfaces with the rust code via FFI.

Features

syntax highlighting
font selection
auto-indent
comment toggling
line breaking
extern crates (with a hacky custom syntax for declaring imports)
use any installed toolchains

Known issues

Performance is not great; it is expected that documents are only ever a few hundred lines.
Drawing is hacky. We may draw ghost selections.

TODO

~~export to gist / web playground~~
export to new cargo project?
rustfmt / clippy
multiple documents, saving snippets?
ASM / IR output

One day, maybe

integrate with cargo-instruments
benchmarking
inline compiler warnings
autocomplete
RLS support
Rust Analyzer support

Thanks

to the xi-editor contributors, to Jake Goulding for the excellent play.rust-lang.org implementation, and to the Rust community at large.
