all I have grammar and when I parse file have following exception on line 113.
[document, program, programs]>>token:[@285,1521:1526='N20G91',<126>,113:0] line:113 charPositionInLine:0 e.token.getText():N20G91
But, when I see on the grammar I suppouse that line N20G91 will be parsed with rule
gcode : GCODE^ xvalue? yvalue? ivalue? jvalue? GCODE? FCODE? ; I.e. first is line number "N20" then I have GCODE G91 But, it's not happends. Have the parsing error instead Where I'm wrong?
Regards, Vladimir
p.s. Please, see grammar and file for the parsing below
