During the migration of the ANTLR4 grammar for ANTLR4 itself, I will write down which steps were needed. That might not apply to ANTLR4's regex-like lexer token definitions. An antlr4 grammar for parsing smali files. To review, open the file in an editor that reveals hidden Unicode characters. Using a file name has the advantage that the module can load file content transparently, if no grammar code is given as string (especially important for dependencies). The failures are broken down like so: antlr - ANTLR failed to generate Go code from the grammar. To review, open the file in an editor that reveals hidden Unicode characters. Use Git or checkout with SVN using the web URL. It then merges the rules, token types, and named actions from the imported grammars into the main grammar. duplicate symbols, unknown symbols).

Grammar formatting, controlled by large set of (dynamically switchable) options. According to Regex - Should hyphens be escaped?, the hyphen should be treated as a character instead of range operator if it is either first or last. Added support for symbol references (e.g. A parser takes a text input, and according to a grammar, extracts the recognized lexicons terms (action of the lexer), and produce an AST: Abstract Syntax Tree (action of the parser).
