How It Works

The Syntax Tree Visualizer demonstrates how compilers and interpreters parse source code into Abstract Syntax Trees. This is a fundamental step in language processing.

Parsing Process

  1. Tokenization: Code is broken down into tokens (keywords, identifiers, operators, etc.)
  2. Parsing: Tokens are organized into a hierarchical tree structure
  3. AST Construction: The tree represents the syntactic structure of the code
  4. Visualization: The tree is displayed for exploration and analysis

Features

  • Operator precedence handling (multiplication before addition, etc.)
  • Function call parsing with argument lists
  • Ternary operator support
  • Interactive node selection and inspection
  • JSON export for further analysis
  • Position tracking (line and column information)
  • Multiple view modes (tree and JSON)
