VerificadorBoletoBr

Essa gem o ajudará a identificar boletos bancários nos seguinte items:

• Banco
• Valor
• Data de Vencimento

e, no caso de boleto de arrecadação:

• Segmento
• Concessionario (Emissor)
• Valor
• Validade (se disponível e "padrão" (🤣🤣🤣🤣) Febraban)

E ainda conferir a validade dos mesmos.

Add this line to your application's Gemfile:

gem 'verificador_boleto_br'

And then execute:

$ bundle

Or install it yourself as:

$ gem install verificador_boleto_br

require './lib/verificador_boleto_br'
>> slip = VerificadorBoletoBr.check('34191 75801 03928 662935 80573 180009 4 67700000007388')
=> #<VerificadorBoletoBr::Slip::Bank::Validity:0x00007f9f820c7a00 @digitable_line="34191 75801 03928 662935 80573 180009 4 67700000007388", @kind=:bank_slip>

It will return the respective slip class with its methods:

>> slip.valid?
=> true
>> slip.bank_code
=> 341
>> slip.currency_code 
=> 9
>> slip.kind
=> :bank_slip
>> slip.value_in_cents
=> 7388
>> slip.value
=> 73.88
>> slip.due_date
=> #<Date: 2016-04-20 ((2457499j,0s,0n),+0s,2299161j)

>> slip = VerificadorBoletoBr.check('858900000018 097802702000 323858108001 011520190292')
=> #<VerificadorBoletoBr::Slip::Arrecadation::Validity:0x00007f9f821bbd08 @digitable_line="858900000018 097802702000 323858108001 011520190292", @errors=[], @kind=:arrecadation_slip>
>> slip.valid?
=> true
>> slip.kind
=> :arrecadation_slip
>> slip.value_in_cents
=> 10978
>> slip.value
=> 109.78
>> slip.due_date
=> nil # if unavailable
>> slip.segment
=> "Órgãos Governamentais"
>> slip.identification
=> "Guia GPS - INSS"

You can access the slip classes directly if you want.

slip = VerificadorBoletoBr.translate_barcode('34196773300001455851090806185172938349558000')
=> #<VerificadorBoletoBr::Slip::Bank::CodeAssembly:0x00007f9f84810990 @code="34196773300001455851090806185172938349558000">
>> slip.digitable_line 
=> "34191090810618517293683495580009677330000145585"

Some bank slips do not validate the global digit well (anybody, feel free to explain me if my theory is correct) for example credit card slips (eg: NuBank). It may be because credit card bills can be paid with any value and global verification ensures that the value is also correct. This method allows to validate bank slips without global digit validation:

slip.valid_without_global?

Encontrei a lista de identificadores de bolego no repositório do Rodrigo Stuchi (https://github.com/rod-stuchi) Obrigado cara.. não sei a origem dos dados (porque não consegui com a Febraban) mas parabens ;)
