This manual page was written for the Debian distribution because the original program does
not have a manual page.

jjtree is a tree builder for javacc

jjdoc is a documentation generator javacc


javacc, jjtree or jjdoc without any argument prints a small help with the list of
available options.

"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 or a string value.

For a list of available options, please refer to the command's internal help.


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

% jjtree -STATIC=false mygrammar.jjt

% jjdoc mygrammar.jj
