JavaCC Command Line Syntax

# JavaCC [tm]: Command Line Syntax

First, you can obtain a synopsis of the command line syntax by simply typing "javacc". This is what you get:

    % javacc
    <<<< Version and copyright info>>>

    Usage:
        javacc option-settings inputfile

    "option-settings" is a sequence of settings separated by spaces.
    Each option setting must be of one of the following forms:

        -optionname=value (e.g., -STATIC=false)
        -optionname:value (e.g., -STATIC:false)
        -optionname       (equivalent to -optionname=true.  e.g., -STATIC)
        -NOoptionname     (equivalent to -optionname=false. e.g., -NOSTATIC)

    Option settings are not case-sensitive, so one can say "-nOsTaTiC" instead
    of "-NOSTATIC".  Option values must be appropriate for the corresponding
    option, and must be either an integer, a boolean, or a string value.

    The integer valued options are:

        LOOKAHEAD              (default 1)
        CHOICE_AMBIGUITY_CHECK (default 2)
        OTHER_AMBIGUITY_CHECK  (default 1)

    The boolean valued options are:

        STATIC                 (default true)
        SUPPORT_CLASS_VISIBILITY_PUBLIC (default true)
        DEBUG_PARSER           (default false)
        DEBUG_LOOKAHEAD        (default false)
        DEBUG_TOKEN_MANAGER    (default false)
        ERROR_REPORTING        (default true)
        JAVA_UNICODE_ESCAPE    (default false)
        UNICODE_INPUT          (default false)
        IGNORE_CASE            (default false)
        COMMON_TOKEN_ACTION    (default false)
        USER_TOKEN_MANAGER     (default false)
        USER_CHAR_STREAM       (default false)
        BUILD_PARSER           (default true)
        BUILD_TOKEN_MANAGER    (default true)
        TOKEN_MANAGER_USES_PARSER (default false)
        SANITY_CHECK           (default true)
        FORCE_LA_CHECK         (default false)
        CACHE_TOKENS           (default false)
        KEEP_LINE_COLUMN       (default true)

    The string valued options are:

        OUTPUT_DIRECTORY       (default Current Directory)
        TOKEN_EXTENDS          (java.lang.Object)
        TOKEN_FACTORY          (java.lang.Object)
        JDK_VERSION            (1.5)
        GRAMMAR_ENCODING       (default file.encoding)

    EXAMPLE:
        javacc -STATIC=false -LOOKAHEAD:2 -debug_parser mygrammar.jj

Any option may be set either on the command line as shown in the help message above, or in the grammar file as described in JavaCC grammar syntax. The effect is exactly the same.

If the same option is set in both the command line and the grammar file, then the option setting in the command line takes precedence.
