CSV::Row#delete_if

row.delete_if {|header, value| ... } → self

# File tmp/rubies/ruby-3.3.0/lib/csv/row.rb, line 476
def delete_if(&block)
  return enum_for(__method__) { size } unless block_given?

  @row.delete_if(&block)

  self  # for chaining
end

Removes fields from self as selected by the block; returns self.

Removes each field for which the block returns a truthy value:

Example

source = "Name,Name,Name\nFoo,Bar,Baz\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.delete_if {|header, value| value.start_with?('B') } # => true
row # => #<CSV::Row "Name":"Foo">
row.delete_if {|header, value| header.start_with?('B') } # => false

If no block is given, returns a new Enumerator:

Example

row.delete_if # => #<Enumerator: #<CSV::Row "Name":"Foo">:delete_if>
