Swamp Pretty Printer

Provides functions to format and display internal data structures from the Swamp programming language compiler in a human-readable, colorized way.

Overview

This crate is a debugging and inspection tool for developers working on the Swamp compiler. It takes complex internal representations like the Abstract Semantic Graph (swamp_semantic::Expression), type structures (swamp_types::Type), symbol tables (swamp_modules::SymbolTable), etc., and formats them into indented, color-coded strings.

It utilizes swamp-source-map-lookup to include source text snippets and yansi for terminal colorization.

Key Features

• Formats Internal Structures: Pretty-prints Expression, Type, SymbolTable, Modules, AssociatedImpls, and more.
• Color Highlighting: Uses terminal colors to differentiate between different kinds of symbols, types, and syntax elements.
• Indentation: Uses indentation to reflect the structure of the data (e.g., nested expressions, struct fields).
• Source Integration: Leverages SourceMapLookup to display identifiers based on their source text.

Core Structures

• SourceMapDisplay: A wrapper around a SourceMapLookup implementation that provides the core formatting methods.
• SymbolTableDisplay, ExpressionDisplay, etc.: Wrapper structs that implement std::fmt::Display by using SourceMapDisplay to format the contained compiler structure.

Installation

This crate is primarily intended for use within the Swamp compiler or related debugging tools.
