--NoDr - YGO--

The better way to learn new language is writing code so I do it.

This is the premices of a dates/calendar lib.
Actually it is not finished yet, but some part seem to work. It is not tested at all, so, probably buggy.
I am not sure the code is the clever one because I am still not confident with Factor and also because I am pragmatic … if it works fine … let’s go … I leave the subjective beauty of the code for purist.

Uncompress this CALENDAR in Factor/library and go

• TEST

  new-calendar .s  (word for today <calendar> )
  << calendar [ ] 1121715062216 12982 70262 2005 199 7 18 19 31 2 “fr” 0 “fr” >>
  dup print-fmt .
  “18/7/2005 19:31″
  dup 2 swap settimezone
  dup print-fmt-fr-full .
  “Lundi 18/7/2005 21:31:2 GMT:2″

COMMENT and QUERY
The <calendar> is immutable ( except the fact TUPLE is not immutable .. I have to learn deeper this)
- The millisec field is ALWAYS express in GMT 0.
- Other fields are the externals representation of the date according the timelag
- settimezone create new calendar with same millisec but different representation (don’t know if it is a good idea)

• DATES

  primitives for dates computations

• CALENDAR

  calendar classes

• LOCALES

  printer and parser (not yet done) for differents locales

I wonder if TUPLE should not have something like :R or :RW modifyer to change the built of the words associated
( :R doesn’t create mutator for field while :RW does and default :R)

I hope I’ll finish calendar soon
