vf-parser

Parser for Salesforce Visualforce. This is based on an ANTLR4 grammar, see antlr/ApexParser.g4.

There are two builds of the parser available, a NPM module for use with Node and a Maven package for use on JVMs.

These builds just contain the Parser & Lexer and provides no further support for analysing the generated parse trees beyond what is provided by ANTLR4.

Example

To parse a page file (NPM version):

let lexer = new VFLexer(CharStreams.fromString("<apex:page/>"));
let tokens = new CommonTokenStream(lexer);

let parser = new VFParser(tokens);
let context = parser.vfUnit();

The 'context' is a VfUnitContext object which is the root of the parsed representation of the page. You can access the parse tree via functions on it.
