Drafts Directory: eval lines

Action

Last update over 6 years 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";
      }  
      return output;    
    }
