Crate perl_dap_variables 

Variable rendering for Perl DAP

This crate provides types and utilities for rendering Perl variables in the Debug Adapter Protocol (DAP) format, enabling debugging support in VSCode and other DAP-compatible editors.

Overview

The crate provides:

• PerlValue - Represents Perl values (scalars, arrays, hashes, references)
• RenderedVariable - DAP-compatible variable representation with lazy expansion
• VariableRenderer - Trait for custom variable rendering strategies
• PerlVariableRenderer - Default implementation for Perl variables

Example

use perl_dap_variables::{PerlValue, RenderedVariable, PerlVariableRenderer, VariableRenderer};

let renderer = PerlVariableRenderer::new();
let value = PerlValue::Scalar("hello".to_string());
let rendered = renderer.render("$greeting", &value);

assert_eq!(rendered.name, "$greeting");
assert_eq!(rendered.value, "\"hello\"");

Parser for Perl debugger variable output.

Enums
