Create new entry with timestamp

Action

Posted by @scripts4drafts, Last update almost 6 years ago

This script creates a new entry in the current draft, right after the entry where the cursor is. The new entry includes a timestamp (YYYY-MM-DD-day hh:mm).

By default, the timestamps are sorted by date and time (i.e. in the last entry, it’s the current date and time, but if you insert an entry between two existing one, it’s the date and time of the following one).

The separator between entries is set in the ‘Init’ function.

Steps

script

function Init() {
  // set separator
  this.sep = '***'; // will be passed to RegExp.quote function
  // set timestamp format and timestamp regexp (both must be consistent)
  let tsf = '%Y-%m-%d-%a %H:%M', // strftime format
    ret = '20[0-9][0-9]-[0-1][0-9]-[0-3][0-9]-\\w\\w\\w [0-2][0-9]:[0-5][0-9]'; // will NOT be passed to RegExp.quote function
  // locate cursor
  this.loc = editor.getSelectedRange()[0];
  // locate the end of current draft
  let eod = draft.content.length;
  // set regexp before
  let reb = new RegExp('^([\\s\\S]*' + RegExp.quote(this.sep) + ')?[\\s\\S]*?$');
  //set regexp after
  let rea = new RegExp('^([\\s\\S]*?)(' + RegExp.quote(this.sep) + '([\\s\\S]*?\\n(' + ret + '))?[\\s\\S]*)?$');
  // regexp before cursor
  editor.getTextInRange(0, this.loc).match(reb);
  // locate start of current entry
  this.sce = (RegExp.$1?RegExp.$1.length:0);
  // regexp after cursor
  editor.getTextInRange(this.loc, eod).match(rea);
  // set length of current entry
  this.lce = this.loc - this.sce + RegExp.$1.length;
  // check if current entry is the last one in draft
  this.ile = (RegExp.$2?false:true);
  // set timestamp of next entry
  let nts = RegExp.$4;
  // set timestamp for new entry
  if (this.ile)
    this.sts = strftime(new Date(), tsf);
  else
    this.sts = (nts?nts:strftime(new Date(), tsf));
  // set current entry
  this.cue = editor.getTextInRange(this.sce, this.lce).trim();
}

Object.prototype.newEntry = function() {
  // modify current entry with no empty lines before and after entry, then add separators
  let str = (!this.sce && !this.cue?this.sep:'') + '\n' + this.cue + (this.cue?'\n' + this.sep + '\n':'') + this.sts + (this.ile?'':'\n');
  // replace current entry with modified entry
  editor.setTextInRange(this.sce, this.lce, str);
  // locate the end of timestamp in new entry
  this.loc = this.sce + str.length - (this.ile?0:1);
  // move the cursor at the end of timestamp in new entry
  editor.setSelectedRange(this.loc, 0);
  editor.setSelectedText('');
}

RegExp.quote = function(str) {
  return str.replace(/([.?*+^$[\]\\(){}|-])/g, '\\$1');
}

let it = new Init();
it.newEntry();
