This article gives some tips and examples for outputting dates in [[:Category:EasyLanguage|EasyLanguage]].
== Relevant EasyLanguage Date reserved words ==
Just as a reminder, the following Date reserved words are often used in working with dates:
* [[Date]], which returns the Date of the current bar in ''YYYMMdd'' format. This date format is always the format with which a date calculation starts.
* [[CurrentDate]], returns the current computer date in ''YYYMMdd'' format.
* [[ELDateToDateTime]], converts a date in ''YYmmdd'' format to a date into DateTime format.
See the [[:Category:Date_and_Time_Routines|Date & Time Routines]] for all EasyLanguage reserved words.
== Outputting the date ==
The following example prints the current date to the [[PowerLanguage Editor]] log:
<syntaxhighlight>
Print("The current date is: ", CurrentDate);
</syntaxhighlight>
Which returns the following sentence: ''The current date is: 1120127.00''.
To output the date in a more readable format, the reserved word [[FormatDate]] is needed. However, FormatDate requires that the date is in DateTime format, while the default Date is in YYYMMdd format. So, a conversion to DateTime is needed first. This is done with the [[ELDateToDateTime]] reserved word.
The code example below shows in detail which steps needs to be made.
<syntaxhighlight>
Variables:
dateToday(0), dateInDateTimeFormat(0), dateReadable("");
// 1. Assign the date of today to the variable 'dateToday'
dateToday = CurrentDate;
Print("The current date in YYYMMdd format is: ", dateToday, NewLine);
// 2. Now, convert the date to DateTime format
dateInDateTimeFormat = ELDateToDateTime(dateToday);
Print("The current date in DateTime format is: ", NumToStr(dateInDateTimeFormat, 5), NewLine);
// 3. Now we can print the current date in a more readable format
dateReadable = FormatDate("dd-MM-yyyy", dateInDateTimeFormat);
Print("The current date in a readable format is: ", dateReadable);
</syntaxhighlight>
This returns the following:
<syntaxhighlight>
The current date in YYYMMdd format is: 1120127.00
The current date in DateTime format is: 40935.00000
The current date in a readable format is: 27-01-2012
</syntaxhighlight>
Of course, not all these steps are needed. The extensive above example can be rewritten to simply:
<syntaxhighlight>
Print("The current date in a readable format is: ", FormatDate("dd-MM-yyyy", ELDateToDateTime(CurrentDate)));
</syntaxhighlight>
Which returns:
<syntaxhighlight>
The current date in a readable format is: 27-01-2012
</syntaxhighlight>
== Outputting the date in different formats ==
The [[FormatDate]] reserved word has a parameter string by which different date outputs can be generated. For example, in the code above we used “dd-MM-yyyy” to return “27-1-2012”.
The code example below shows some of these parameter options for FormatDate (see the [[FormatDate]] article for an extensive list of parameter options).
<syntaxhighlight>
Variables:
dateInDateTime(0);
dateInDateTime = ELDateToDateTime(CurrentDate);
Print("Date in short version: ", FormatDate("d-M-y", dateInDateTime), NewLine);
// Note: the output of the following statement depends on your regionale
Print("Date in abbreviations: ", FormatDate("ddd-MMM-yy", dateInDateTime), NewLine);
Print("Date fully written: ", FormatDate("dddd MMMM yyyy", dateInDateTime), NewLine);
Print("Date in a sentence: ",
FormatDate("The current Date is dddd anD the month is MMMM (which is month #MM). The Year is yyyy.", dateInDateTime));
end;
</syntaxhighlight>
This gives the following output:
<syntaxhighlight>
Date in short version: 27-1-12
Date in abbreviations: vr-jan-12
Date fully written: vrijdag januari 2012
Date in a sentence: The current Date is vrijdag anD the month is januari (which is month #01). The Year is 2012.
</syntaxhighlight>
