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