Time Range Extractor

This gem makes it easy to extract a time range from some text. The goal is to be able to pull out start and end times from a body of text so that you can give more context to the information.

For example:

result = TimeRangeExtractor.call("Meet with Jessie from 4-5pm")
result.begin
#=> 2019-06-20 16:00:00 -0700
result.end
#=> 2019-06-20 17:00:00 -0700

A few caveats:

• Only reads out the first time it can find
• If only one time is found, that becomes the start time
• Only the last time zone is taken into account
• Doesn't support 24 hour clocks yet
• Likely no support for international times
• Check the test suite for supported cases

Add this line to your application's Gemfile:

gem 'time_range_extractor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install time_range_extractor

result = TimeRangeExtractor.call("Meet with Jessie from 4-5pm")
result.begin
#=> 2019-06-24 16:00:00 -0700
result.end
#=> 2019-06-24 17:00:00 -0700

result = TimeRangeExtractor.call("Meet with Jessie at 4pm EDT", date: 4.days.ago.to_date)
result.begin
#=> 2019-06-20 16:00:00 -0400
result.end
#=> 2019-06-20 16:00:00 -0400

Time.zone = 'America/Vancouver'

result = TimeRangeExtractor.call("Meet with Jessie at 4pm EDT", date: 4.days.ago.to_date)
result.begin
#=> Thu, 20 Jun 2019 13:00:00 PDT -07:00
result.end
#=> Thu, 20 Jun 2019 13:00:00 PDT -07:00
