Module repl 

Top-level runner: parse → lower → evaluate.

TopLevel is a thin wrapper that accumulates an environment and staging context. There is no define, no macro system, no prelude - the language is exactly λ↑↓ from the paper. All recursion goes through the lambda self-ref slot; all naming goes through let.

Re-exports

pub use runner::eval_str;

pub use runner::load_file;

pub use runner::run_repl;

Modules

commands

REPL command implementations (:help, :env, :ctx, :load, :reset).

highlight

Syntax highlighting and bracket validation for the narju REPL.

runner

The interactive REPL loop and file/expression runners.

Structs

RunResult

The outcome of evaluating one top-level form.

TopLevel

Accumulated evaluator state: environment vector and staging context. Exists purely as a convenience for multi-expression REPL sessions.

Functions

parse_all

Read every form in src, wrapping reader failures in NarjuError::Parse. A thin shim over crate::parse::parse_all, whose error type is a bare String.

run_form

Execute a single pre-parsed form, evaluating it in top’s current env. Every form is an expression — there are no top-level special forms.
