Utilities for transforming dates within Maptitude GIS. GPLv3 license.

DateWidget.rsc contains five macros:

"Test"  is a simple demo allowing you to explore the functionality of the DateWidget.

"Date Field" provides a more applied demo of the DateWidget. This macro adds a new field (whose name is specified in the administrative settings) to hold the widgetized date (whose format is also specified in the administrative settings). It will then loop through all records, read the contents of the date field, and then write the widgetized date in the format specified in the options. The "Sample_dates.bin" file is provided as demo data.

"DateWidget" is the main macro. It converts dates from all-numeric formats, e.g. 2/14/2011 to formats such as February 14, 2011. If you use the string "today" for a date, it will produce today's date in the desired format. The macro takes two options related to input: date type (e.g. MDY vs. DMY) and separator (e.g. 2/14/2011 vs. 2-14-2011). It also accepts five options related to output: format (e.g. Monday, February 14, 2011 vs. 14-02-2011); day (include day of week if format is not otherwise specified); longmonth (e.g. Feb vs. February); zeroes (02/01/2011 vs. 2/1/2011); and language.

"DOW" is a helper macro for DateWidget, but may also be used separately,. It macro converts an English day of the week to another language. The first parameter, american_date, is a date of the form "MM/DD/YYYY". The second parameter, days, is an array of days of the week in the target language, beginning with Sunday.

"Today" is another helper macro for DateWidget that may be used separately. It converts today's date (via Maptitude's GetDateAndTime() function) into an American-style (MM/DD/YYYY) date, which is the format Maptitude requires for its built-in date functions.
