Fix Date Parser Accidentally Parsing Two-Digit Number as Year

[bytrangle]

Description

When user creates a new task which includes short syntax for date, then following by a two-digit number, the number will be interpreted as year.

For example: "Task @14/4 90m". Implication: User schedules the task for 14/4 going forward and estimates the task as taking 90 minutes. Two problems:

• This task will be scheduled for 14/4/1990 because Chrono understands 90 as 1990.
• The task title will include the word "m" when it should have been escaped.

Changes I've made:

• Write a custom parser that checks if the task title contains string in the format of DD/MM YY. The regex pattern is more complicated than that, because there are so many ways a user can write date informally. It doesn't take into account syntax like "August 8 90m".
• The parser will set the year for the task to the current year or a year in the future
• The parseScheduledDate is changed so that the word "m" won't be a part of the final task title.

• [nitpick] The hacky check for a time estimate appended to the date might not handle all edge cases. A clearer separation of date and time estimate parsing would improve robustness.

if (inputDate.match(/ [0-9]{1,}m/g)) {

Replacing the two-digit year indiscriminately may remove matching digits elsewhere in the string. Consider targeting the exact location of the match or using a more precise replacement strategy.

Suggested change

	result.text = text.replace(twoDigits, '');
	const startIndex = matched.index + matched[0].lastIndexOf(twoDigits);
	const endIndex = startIndex + twoDigits.length;
	result.text = text.slice(0, startIndex) + text.slice(endIndex);
