Module: Tins::Full

Defined in:

lib/tins/xt/full.rb

Overview

Provides methods for checking if objects are “full” (non-blank) and safely processing them in conditional contexts.

This module adds the ‘full?` and `all_full?` methods to all objects, enabling clean, readable patterns for validation and conditional processing.

Examples:

Basic usage

"hello".full?        # => "hello"
"".full?             # => nil

Method dispatch with block

user.full?(:name) { |name| "Hello #{name}" }  # Returns "Hello John" if name is full

Safe assignment and processing

if name = user.full?(:name)
  puts "Hello #{name}"
end

Instance Method Summary

• #all_full? ⇒ Object^?

  Checks if all elements in a collection are “full” (not blank).

• #full?(dispatch = nil, *args) {|Object| ... } ⇒ Object^?

  Checks if the object is not blank, returning the object itself if it’s full, or nil if it’s blank.

Instance Method Details

#all_full? ⇒ Object^?

Checks if all elements in a collection are “full” (not blank). If the object responds to all? and all elements pass the full? test, then the block is executed with the collection itself or the collection is returned.

Examples:

Basic usage

[1,2,3].all_full?    # => [1,2,3]
[1,nil,3].all_full?  # => nil

With block execution

[1,2,3].all_full? { |array| array.sum }

# File 'lib/tins/xt/full.rb', line 74

def all_full?
  if respond_to?(:all?) && all?(&:full?)
    block_given? ? yield(self) : self
  end
end

#full?(dispatch = nil, *args) {|Object| ... } ⇒ Object^?

Checks if the object is not blank, returning the object itself if it’s full, or nil if it’s blank. If a method name is provided as dispatch, that method is called on the object and the result is checked for being full.

dispatched result not nil

Examples:

Basic usage

"hello".full?        # => "hello"
"".full?             # => nil

Method dispatch

user.full?(:name)    # Returns user.name if not blank, nil otherwise

Method dispatch with arguments

user.full?(:method_with_args, arg1, arg2)

With block execution

user.full?(:name) { |name| "Hello #{name}" }

Yields:

• (Object) —

  Optional block to execute with the result if result or
