* Added org.antlr.tool.Strip (reads from file arg or stdin, emits to
stdout)
to strip actions from a grammar.
Leon: you can use this now for morph and can remove your strip...let
me know if it's good enough.
Sample input:
/** sdkfljdksafl
* sakljd
*/
grammar T; // ckjfdsl
options {k=1; output=AST;}
@parser::header {...}
@members {
akdsfljklas
}
z
scope A;
: q=a[34] ids+=ID
;
a[int i] returns [float f]
options {k=1;}
@init {rmoeve}
: {sfkljlsf} B^
| '3' -> '3'
{aaa}
;
b
scope {
String name;
}
: B
-> {$arg!=null&&op!=null}? ^($op RULE_REF $arg)
-> ^(RULE_REF $arg)
;
c : {true}? B | {false}?=> C ;
/** dsklfjds */
fragment A : '0' {foo} ;
B : ~A
'z' ;
Output:
/** sdkfljdksafl
* sakljd
*/
grammar T; // ckjfdsl
options {k=1; output=AST;}
@parser::header {...}
z
: a ID
;
a
options {k=1;}
: B
| '3' ;
b
: B
;
c : /*{true}?*/ B | /*{false}?=>*/ C ;
/** dsklfjds */
fragment A : '0' {foo} ;
B : ~A
'z' ;
