Php Token Stream
php-token-stream is a lexical analysis tool and tokenizer wrapper for PHP. It functions as a source code streamer that reads tokens one by one, preventing the need to load entire source files into memory.
The project provides memory-efficient parsing by wrapping the native PHP tokenizer extension. This allows for the sequential processing of source code tokens to analyze structural components and syntax.
The tool is designed for static code analysis and the development of compiler tooling. It supports linear token processing and sequential traversal to examine language constructs and project structures.
Features
- Lexical Analyzers - Functions as a lexical analyzer that breaks PHP source code into a stream of tokens for analysis.
- Tokenizer Wrappers - Wraps the native PHP tokenizer extension to provide a memory-efficient streaming interface.
- Memory-Efficient Parsing - Minimizes memory overhead when analyzing large PHP files by streaming tokens instead of loading the full source.
- Lexical Token Streams - Represents PHP source code as a sequence of discrete tokens for syntactic and structural analysis.
- PHP Code Analysis - Analyzes the structure and syntax of PHP source code token by token without loading entire files.
- Source Code Streamers - Reads PHP tokens one by one as a stream to prevent loading entire source files into memory.
- Source Code Token Streaming - Implements an iterator-based approach to stream PHP tokens without loading entire source files into memory.
- Compiler Tooling - Provides the sequential token parsing necessary for building PHP compiler and transformation tools.
- Lazy Sequences - Provides a lazy-loading sequence that retrieves tokens only when requested to reduce memory overhead.
- Token Stream Navigators - Maintains a stateful pointer within the token sequence to support sequential traversal and look-ahead operations.
- Linear Tokenizers - Processes source code as a one-dimensional stream of tokens to simplify structural analysis.
- Static Code Analysis Tools - Enables the examination of PHP source code for bugs and structural patterns without executing it.
