Accept date that is supplied relatively (yesterday, 2 days ago)

[icyflame]

This has a lot of possibility.

Can start with simple strings like yesterday, #{n} days ago, but can also be improved to last Wednesday, a week ago (which should resolve to 7 days ago)

This should be implemented as a separate module: (if one doesn't already exist)

• which takes one argument and the present Date() (defaults to Date() if not supplied)
• parses the argument, returns a Date() object.
• can be given conditionals such must be in the past, must be in the future, etc.

I have not tested this, but I am thinking along these lines. Have a look and comment.

  date_options = {
    "today" : 0,
    "yesterday" : 24*60*60*1000 ,
    "day" : 24*60*60*1000,
    "week" : 7*24*60*60*1000,
    "weeks" :7*24*60*60*1000 
  }

  if (expenseObject.date) {
    var dateRe = /(\d{4})-(\d{2})-(\d{2})/;
    var matchObject = expenseObject.date.match(dateRe);
    if (!matchObject) {
      var datesplit = expenseObject.date.split(" ")
      if (isNaN(parseInt(datesplit[0]))) {
        if(date_options.slice(0,2).indexOf(datesplit[0])==-1) {
          throw new Error(Consts.MSG_INVALID_DATE);
        } else {
          expenseObject.date = require('date-format').asString('yyyy-MM-dd', new Date().setTime((new Date()).getTime()-datesplit[0]));
        }
      } else {
        if(date_options.slice(2).indexOf(datesplit[1])==-1) {
          throw new Error(Consts.MSG_INVALID_DATE);
        } else {
          expenseObject.date = require('date-format').asString('yyyy-MM-dd', new Date().setTime((new Date()).getTime()-datesplit[1])); 
        }
      }

    }

  } else {
    expenseObject.date = require('date-format').asString('yyyy-MM-dd', new Date());
  }

@light94 Thanks a lot for that snippet of code. I couldn't really get the nested if statements, but I did understand your thinking behind this.

I have setup everything both in this module terminal-wallet and also, I have created a new module relative-date-reverse, which will house the code for solving this problem.

I have used some of the code above, and cleaned it up, and used it to implement basic stuff like yesterday, day before yesterday, etc)

I hope you can find some time to help me out on that module! (index.js)
