NAME

Catmandu::Fix::Condition::in - only execute fixes the data in one path is contained in another

SYNOPSIS

#-------------------------------------------------------------------
# Compare single values
# foo => 42 , bar => 42 => in(foo,bar) -> true
if in(foo,bar)
   add_field(forty_two,ok)
end

# When comparing single values to an array: test if the value is 
# contained in the array  

# foo => 1 , bar => [3,2,1]  => in(foo,bar) -> true
if in(foo,bar)
   add_field(test,ok)
end

# foo => 42 , bar => [1,2,3] => in(foo,bar) -> false
unless in(foo,bar)
   add_field(test,ok)
end

# In the following examples we'll write in pseudo code the true/false
# values of some 'in()' comparissons

# scalars vs arrays - check if the value is in the array
foo: 42 , bar: [1,2,3]                   in(foo,bar) -> false
foo: 1  , bar: [1,2,3]                   in(foo,bar) -> true

# scalars vs hashes - check if the key is in the hash
foo: name , bar: { name => 'Patrick' }           in(foo,bar) -> true
foo: name , bar: { deep => {name => 'Nicolas'}}  in(foo,bar) -> false

# array vs array - check if the contents is equal
foo: [1,2] , bar: [1,2]                  in(foo,bar) -> true
foo: [1,2] , bar: [1,2,3]                in(foo,bar) -> false
foo: [1,2] , bar: [[1,2],3]              in(foo,bar) -> false
