Module runner 

The interactive REPL loop and file/expression runners.

Functions

banner_purple

Banner shown when entering the Purple REPL (default narju).

banner_raw

Banner shown when entering the raw λ↑↓ REPL (narju --raw).

eval_str

Evaluate every form in src (the CLI’s -e flag), printing each result. Returns false on the first error, after printing it to stderr.

load_file

Read and evaluate every form in the file at path, printing each result unless silent. Returns false on the first read, parse, or evaluation error, after printing it to stderr — the CLI turns that into a nonzero exit.

make_prompt

The REPL prompt for a given tower level: plain at level 0, with the level in brackets inside a run at level > 0.

run_repl

The raw λ↑↓ read-eval-print loop.
