NAME
ANTLR - ANother Tool for Language Recognition, version 3
SYNOPSIS
antlr3 [args] file.g [ file2.g file3.g ...]
DESCRIPTION
ANTLR (ANother Tool for Language Recognition) is a parser generator for
reading, processing, executing, or translating structured text or bi-
nary files. It's widely used to build languages, tools, and frameworks.
From a grammar, ANTLR generates a parser that can build and walk parse
trees.
-o outputDir
specify output directory where all output generated.
-fo outputDir
same as -o but force even files with relative paths to dir.
-lib dir
specify location of token files.
-depend
generate file dependencies.
-report
print out a report about the grammar(s) processed.
-print print out the grammar without actions.
-debug generate a parser that emits debugging events.
-profile
generate a parser that computes profiling information.
-trace generate a recognizer that traces rule entry/exit.
-nfa generate an NFA for each rule.
-dfa generate a DFA for each decision point.
-message-format name
specify output style for messages.
-verbose
generate ANTLR version and other information.
-make only build if generated files older than grammar.
-version
print the version of ANTLR and exit.
-language L
override language grammar option; generate L
-X display the list of extended arguments
-Xgrtree
print the grammar AST
-Xdfa print DFA as text
-Xnoprune
test lookahead against EBNF block exit branches
-Xnocollapse
collapse incident edges into DFA states
-Xdbgconversion
dump lots of info during NFA conversion
-Xconversiontimeout
use to restrict NFA conversion exponentiality
-Xmultithreaded
run the analysis in 2 threads
-Xnomergestopstates
do not merge stop states
-Xdfaverbose
generate DFA states in DOT with NFA configs
-Xwatchconversion
print a message for each NFA before converting
-XdbgST
put tags at start/stop of all templates in output
-Xnfastates
for nondeterminisms, list NFA states for each path
-Xm m max number of rule invocations during conversion [4]
-Xmaxdfaedges m
max "comfortable" number of edges for single DFA state [65534]
-Xmaxinlinedfastates m
max DFA states before table used rather than inlining [60]
-Xmaxswitchcaselabels m
don't generate switch() statements for dfas bigger than m [300]
-Xminswitchalts m
don't generate switch() statements for dfas smaller than m [3]
-Xsavelexer
don't delete temporary lexers generated from combined grammars
