Antlr v4 grammar editor and builder for Eclipse

• Syntax-assisted editing with syntax highlighting, smart editing actions, and folding
• Incremental grammar builder
• Grammar formatter
• Graphical parse tree display with full token and parser/lexer error reporting
• Graphical rule path (connectivity) analysis

The folders containing the 'g4' grammars and the generated files must be on the project classpath, i.e., a Java source folder. Otherwise, AntlrDT has no reliable way of finding them.

From the Antlr tools section of the platform toolbar :

• Tokens View: select the icon.
• Paths View: select the icon.

[workspace root]
  [project]
     /src/main/java
       /your/package/path
         /parser
            YourParser.g4
            YourLexer.g4
            YourTokenFactory.java
            YourToken.java
            /gen
               [[generated files produced here]]
     /test.snippets
       /basic
           [[source snippets]]
       /complex 
           [[source snippets]]

Add the appropriate @header to the lexer and parser grammars:

@header { package your.package.path.parser.gen; }

After opening the token view, be sure to verify the values in the 'Integration' dialog.
