Usage:
java org.antlr.Tool [args] file.g [file2.g file3.g ...]
Option |
description |
---|---|
-o outputDir |
specify output directory where all output is generated; search for token vocabularies in here also |
-fo outputDir |
same as -o but force even files with relative paths to dir |
-depend |
generate file dependencies; don't actually run antlr |
-lib dir |
specify location of token files and important grammars |
-report |
print out a report about the grammar(s) processed |
print out the grammar without actions |
|
-trace |
generate a parser with trace output - if the default output is not enough, you can override the traceIn and traceOut methods |
-debug |
generate a parser that emits debugging events |
-profile |
generate a parser that computes profiling information |
-nfa |
generate an NFA for each rule |
-dfa |
generate a DFA for each decision point |
-message-format name |
specify output style for messages |
-X |
display extended option list |
There are a bunch of less often used "extended" options as well.
