gsh/command/history
The history module provides introspection into the REPL’s chronological
execution log.
It allows users to review their past inputs, formatting the raw string history into a numbered, human-readable list for quick reference.
Values
pub fn show(history: List(String)) -> NilRenders a sequentially numbered list of all previously executed commands within the current active session.
Formatting Logic:
- Iterates through the provided history list and prefixes each command
with its chronological execution index (e.g.,
1 let x = 5). - Safely handles fresh or recently cleared sessions by printing
(empty).
