README
YYMMDD
Tiny DSL for idiomatic date parsing and formatting.
Overview
require "yymmdd"
include YYMMDD
puts yy/mm # 14/08 (i.e., today's date)
puts yyyy/mm # 2014/08
date = ymd(411207) # Date.new(1941, 12, 7)
date = Date.today
puts yyyy.mm.dd(date) # 2014.08.09
puts dd/mm/yy(date) # 08/09/14
puts ymd(date) # 1489
puts yymmdd(date) # 140809
date = yyyy.mm.dd("1941.12.07") # Date.new(1941, 12, 7)
date = mm.dd.yy("11.22.63") # Date.new(1963, 11, 22)
date = mm/dd/yy("11/21/99") # ...
date = mm/dd/yyyy("11/21/1999")
date = mm-dd-yyyy("11-21-1999")
date = m-d-y("11-21-99")
Installation
Rubygems:
gem install yymmdd
Bundler:
gem "yymmdd"
Usage
All functions are module_functions
so you must include YYMMDD to use them.
When given a String it will attempt to parse it as the specified format and return a Date.
When given a Date it will return a String in the specified format.
An ArgumentError is raised if the date can't be parsed or formatted.
With no arguments it will return an instance of a String-like object (it overrides to_s and to_str) representing
today's date in the specified format. In the most common cases you can treat it like a String:
date = yyyy/mm/dd
puts "Today's date: #{date}"
text = ["Dates: ", yy/mm, yyyy/mm].join(", ")
text = "A great date: " << date
But in some instances you'll have to expilictly call to_s:
printf "Today's date: %s\n", date.to_s
All the heavy lifting is done by Date#strftime and Date.strptime.
Format Specifiers
The table below lists the available format specifiers. All of these can be separated by one of the supported
delimiters: "/", ".", or "-".
NameFormat dday of the year, no 0 padding ddday of the year mday of the month, no 0 padding mmday of the month y2 digit year yy2 digit year yyyy4 digit year
There are also combined, delimiterless functions for all combinations of the above, e.g., ymd, mdy, yymmdd, etc...
Caveats
Due to operator precedence you can't mix delimiters.
