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 binary 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 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
