bible_bot

Gem for parsing and working with bible verse references.

Getting Started

# Gemfile
gem 'bible_bot', github: 'LittleLea/bible_bot'
$ bundle install
require 'bible_bot'

# Parsing
references = BibleBot::Reference.parse( "John 1:1 is the first but Rom 8:9-10 is another." )

# Formatting
references.formatted #=> "John 1:1; Romans 8:9-10"
references.map(&:formatted).join( ", " ) #=> "John 1:1, Romans 8:9-10"
reference = references.last
reference.start_verse.formatted #=> "Romans 8:9"
reference.end_verse.formatted   #=> "Romans 8:10"

# Invalid references are skipped by default
BibleBot::Reference.parse( "Genesis 100:1" ) #=> []

# Optionally include invalid references
references = BibleBot::Reference.parse( "Genesis 100:1", validate: false )
references.first.valid? #=> false

# Optionally raise on errors
BibleBot::Reference.parse( "Genesis 100:1", validate: :raise_errors )
# => BibleBot::InvalidVerseError:
#      Verse is not valid: {:book=>"Genesis", :chapter_number=>100, :verse_number=>1}

# Find Books
book = BibleBot::Book.find_by_name("1 John")
book.reference.inspect #=> {:start_verse=>"1 John 1:1", :end_verse=>"1 John 5:21"}

Terms

  • Verse - A single verse in the bible.
  • Reference - A range of two verses. Start and end verse may be equal, in which case it is a single verse reference.
  • ReferenceMatch - A lower level wrapper around regular expression Match results. This class contains all the parsing logic. Except for advanced use cases, use Reference.parse instead.
  • Book - One of the 66 books in the bible.
  • Bible - A wrapper containing all 66 books and the regular expressions used for parsing.

Supported Abbreviation Rules

  • May abbreviate the book title. See BibleBot::Bible for which book abbreviations are supported.
"Gen 1:1"
  • May omit the end book if it is the same as the start book.
"Genesis 1:1-2:3"  #=> Genesis 1:1 - Genesis 2:3
  • May omit the end chapter if it is the same as the start chapter.
"Genesis 1:1-3"    #=> Genesis 1:1 - Genesis 1:3
  • May omit the verse number if the reference includes the entire chapter.
"Genesis 1"    #=> Genesis 1:1 - Genesis 1:31
"Genesis 1-2"  #=> Genesis 1:1 - Genesis 2:25

Persisting References and Verses

A Reference is made up of two Verse objects.

reference.start_verse
reference.end_verse

Each verse is represented by an integer ID that can be stored in your database.

#   |- book.id
#   |   |- chapter_number
#   |   |   |- verse_number
#   XX_XXX_XXX

reference.start_verse.id #=> 1_001_001  (Genesis 1:1)
reference.end_verse.id   #=> 2_010_020  (Exodus 10:20)

How you store the start_verse and end_verse is up to you.

To re-instantiate a reference, you can use Reference.from_verse_ids(:start_verse_id, :end_verse_id).

Reference.from_verse_ids(1_001_001, 2_010_020)

# Which is shorthand for
Reference.new(
  start_verse: Verse.from_id(1_001_001),
  end_verse: Verse.from_id(2_010_020)
)

Comparing References

If you want to see if a Reference intersects any you have stored in your database, you might do something like:

Foo.where("start_verse_id <= ?", reference.end_verse.id)
   .where("end_verse_id >= ?", reference.start_verse.id)

Reference and Verse also have built in methods for comparing against each other.

reference.intersects_reference?(other_reference)
reference.includes_verse?(verse)
verse < other_verse
verse == other_verse
verse > other_verse

Apocryphal References

If you want to match apocryphal references in your strings, you can enable a collection of matchers like this:

BibleBot.include_apocryphal_content = true

ReferenceMatch.scan( "Tob 1:1" ).first.reference.formatted

# > "Tobit 1:1"

You can see the supported apocryphal works in bible.rb
