Crate jay 

libjay core: compiles J/APL expressions to a shared IR and executes them.

The public surface is deliberately PCRE-shaped: compile turns a string into a reusable Program; running it with data is a separate step owned by the caller.

Modules

array

Dense multidimensional array: a shape and a flat row-major buffer.

complex

Complex arithmetic on interleaved [re, im] pairs.

device

Where a compiled expression runs.

dtype

Element types. The set is deliberately small; nothing here may assume it stays small.

error

Error type carrying a position in the user’s source expression.

exact

Exact numbers: arbitrary-precision integers and rationals.

fmt

Human-readable array formatting, J session style: numeric columns aligned, higher-rank arrays printed as planes separated by blank lines.

frontend

Language frontends. Each parses its own syntax into the shared IR.

fuse

Fusing chains of elementwise verbs into one blockwise pass.

ir

The language-agnostic program representation and its evaluator.

limits

The ceiling on how large a single value may be.

simd

Runtime dispatch over CPU feature levels.

verb

Verbs and the rank machinery: the language-agnostic execution core.
