INT : ('0' .. '9')+ ;
MUL : '*' ;
DIV : '/' ;
ADD : '+' ;
SUB : '-' ;
LP : '(' ;
RP : ')' ;
WS : [ \r\n\t] + -> skip ;
Command:
trparse Expression.g4 | trdelete "//parserRuleSpec[RULE_REF/text() = 'a']" | trprint

grammar Expression;

# Notes
If you are running MSYS2 on Windows, you may notice that XPaths are not being
processed by this command correctly. To avoid the Bash shell from altering
XPaths, type _export MSYS2_ARG_CONV_EXCL="*"_, then execute your command.
