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