Datemath
Elasticsearch's date parser for Ruby
Installation
Add this line to your application's Gemfile:
gem 'datemath'
And then execute:
$ bundle
Or install it yourself as:
$ gem install datemath
Usage
Datemath uses Elasticsearch's date parser to handle date expressions.
Here are a few examples:
Current date time:
Datemath::Parser.new("now").parse
Specific date time:
Datemath::Parser.new("2015-05-05T00:00:00").parse
Complex expression:
Datemath::Parser.new("now+1d").parse
Multiple operations:
Datemath::Parser.new("now+1d-1m").parse
Rounding:
Datemath::Parser.new("now+1d-1m/d").parse
Anchoring dates:
Datemath::Parser.new("2015-05-05T00:00:00||+1d-1m").parse
