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
-
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
