lead

Redesign + rewrite of ayr, a toy array language intended for code golfing. The rewrite takes a more general purpose approach, although most of the symbols will be lifted from the previous version.

Building

Clone the repository to a local location. Run

cargo install --path lead-cli

Use

cargo install --path lead-cli --features ffi

to compile with the supporting FFI linking internals []extern and []link.

For building the webserver, ensure you have wasm-bindgen installed and accessible on the path. Use

RUSTFLAGS='--cfg=getrandom_backend="wasm_js"' cargo build --package lead-wasm --target=wasm32-unknown-unknown --release
wasm-bindgen --out-dir ./docs/pkg ./target/wasm32-unknown-unknown/release/lead_wasm.wasm --target web

to build the files into the ./docs directory

Syntax (tentative)

[~] 2 * ~e9    -- Don't print
mean: +/%#     -- Define literal
mean ~25       -- Mean 1..=25
'hello world'  -- String
map: [:]{ a: 'first'; b: 'second' }
map.a        -- 'first'
map.('b')    -- 'second'
[]I          -- STDIN?

TODO

• Non-instant groups (mainly trains)
• Operators
• Proper @ rank support
• Recursive blocks via v
• Port symbols + operators
• Support maps in some functions?
• Maps
• Support variadic accessors?
• Accessors
• Tables?
