eval lines

Last update about 1 year ago

Does a JS eval on every line of your draft and plops the result at the end of the line.

Some things to try:

5+5 # 10
Math.PI * 2 # 6.283185307179586
var x=8675309
x/3 # 2891769.6666666665

Steps

  • script

        function evalLines(text){
          var lines = text.split("\n");
          var output = "";
    
          for(var i=0;i<lines.length;i++){
            var line = lines[i];
            if(line.indexOf("#")>-1){
              line = line.substring(0,line.indexOf("#"));
            }
            var result = "";
            try{
              result = eval(line);
              if(result == undefined){
                result = "";
              }
            }catch(error){
              result = "error";
            }
            output += line;
            if(result != ""){
              output += " # "+result;
            } 
            output += "\n";
          }
