PHP Parser Syntax Visualizer Tool

Overview

VSCode Extension that demonstrates some of the basic usage and functionality of the parser.

• writes AST to adjacent *.ast file using JSON representation
• Error squigglies

Instructions

1. npm install client/server dependencies, run Extension
2. open PHP file from example folder, and *.ast file to the side
3. check out error information, and corresponding AST
4. make some changes, and save to view updates

Settings

• php.syntaxVisualizer.parserPath: set this path to use a different parser version than the one bundled with the syntax visualizer. For instance, after git clone https://github.com/Microsoft/tolerant-php-parser, set php.syntaxVisualizer.parserPath to the absolute directory of the tolerant-php-parser/src folder. This will enable you to easily debug the parser during development.
