Rite

Define validators for Ruby classes and objects. Rite provides a simple, chainable validator solution based on the principles of functional design: small, composable validators used to build complex validation logic.

• gemspec
• Validator base class
• Basic validators
  • type validator
  • value validator
  • required validator
  • numeric validator
  • hash validator
  • array validator
• Transformers (chainable with validators but transform data/error messages)
• Passage
• "Friendly" DSL
  • DSL for validator
    • define validate function
    • define custom failure message
    • define error handling
  • DSL for transformer
  • DSL for Passage

Add this line to your application's Gemfile:

gem 'rite'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rite

# Define a schema for SSNs
ssn_schema = Rite
  .string
  .matches(/\d{3}-\d{2}-\d{4}/)

ssn_schema.parse!('apple') # => raises Rite::Error
ssn_schema.parse('000-00-0000') # => returns Rite::Result
# result.success? => true
# result.value => '000-00-0000'

# Define the schema
positive_integer_schema = Rite
  .integer
  .positive

# validate data with it
positive_integer_schema.parse!(1) # => 1
positive_integer_schema.parse(-8) # => Rite::Result
# result.success? => false
# result.failed? => true
# result.error => Rite::Error
