Swamp Parser

Parses Swamp programming language source code text into an Abstract Syntax Tree (AST).

Overview

This crate takes a string containing Swamp source code and attempts to parse it according to the grammar defined in src/grammar.pest. If successful, it produces an AST representation using the data structures defined in the swamp-ast crate. If the source code contains syntax errors, it returns a ParseError.

The parser is built using the pest parser generator library.

Key Features

• Input: Swamp source code as a &str.
• Output: A Result<swamp_ast::Module, ParseError>.
• AST: The success variant contains the root of the Abstract Syntax Tree (swamp_ast::Module).
• Error Handling: The error variant (ParseError) provides information about the location and nature of the syntax error.
• Span Information: Attaches source location information (swamp_ast::Node containing SpanWithoutFileId) to the generated AST nodes.
