Code:
`+this.showPosition(),{text:"",token:null,line:this.yylineno});return this},less:function(Si){this.unput(this.match.slice(Si))},pastInput:function(){var Si=this.matched.substr(0,this.matched.length-this.match.length);return(Si.length>20?"...":"")+Si.substr(-20).replace(/\n/g,"")},upcomingInput:function(){var Si=this.match;return Si.length<20&&(Si+=this._input.substr(0,20-Si.length)),(Si.substr(0,20)+(Si.length>20?"...":"")).replace(/\n/g,"")},showPosition:function(){var Si=this.pastInput(),Oi=new Array(Si.length+1).join("-");return Si+this.upcomingInput()+`
