This module contains basic methods for accessing and defining element and mark attributes.
An attribute is a key value pair. It's used to store information on an element or mark. Information you can store are things like color, font type, or image or link locations.
StringAttribute "href" "www.google.com"
findBoolAttribute : String -> List Attribute -> Maybe Basics.Bool
Find the first BoolAttribute that has the name provided and return Just that value. If no attribute exists, return Nothing.
findBoolAttribute "foo" [ BoolAttribute "foo" True, StringAttribute "foo2" "bar2" ]
--> Just True
findFloatAttribute : String -> List Attribute -> Maybe Basics.Float
Find the first FloatAttribute that has the name provided and return Just that value. If no attribute exists, return Nothing.
findFloatAttribute "foo" [ FloatAttribute "foo" 1.1, StringAttribute "foo2" "bar2" ]
--> Just 1.1
findIntegerAttribute : String -> List Attribute -> Maybe Basics.Int
Find the first IntegerAttribute that has the name provided and return Just that value. If no attribute exists, return Nothing.
findIntegerAttribute "foo" [ IntegerAttribute "foo" 1, StringAttribute "foo2" "bar2" ]
--> Just 1
findStringAttribute : String -> List Attribute -> Maybe String
Find the first StringAttribute that has the name provided and return Just that value. If no attribute exists, return Nothing.
findStringAttribute "foo2" [ FloatAttribute "foo" 1.1, StringAttribute "foo2" "bar2" ]
--> Just "bar2"
replaceOrAddBoolAttribute : String -> Basics.Bool -> List Attribute -> List Attribute
Replaces all BoolAttributes that have the name provided in the list, or add it to the beginning of the list if no pre existing BoolAttribute exists.
replaceOrAddBoolAttribute "foo" True [ BoolAttribute "foo" False, StringAttribute "foo2" "bar2" ]
--> [ BoolAttribute "foo" True, StringAttribute "foo2" "bar2" ]
replaceOrAddFloatAttribute : String -> Basics.Float -> List Attribute -> List Attribute
Replaces all FloatAttributes that have the name provided in the list, or add it to the beginning of the list if no pre existing FloatAttribute exists.
replaceOrAddFloatAttribute "foo" 2.2 [ FloatAttribute "foo" 1.1, StringAttribute "foo2" "bar2" ]
--> [ FloatAttribute "foo" 2.2, StringAttribute "foo2" "bar2" ]
replaceOrAddIntegerAttribute : String -> Basics.Int -> List Attribute -> List Attribute
Replaces all IntegerAttributes that have the name provided in the list, or add it to the beginning of the list if no pre existing IntegerAttribute exists.
replaceOrAddIntegerAttribute "foo" 2 [ IntegerAttribute "foo" 1, StringAttribute "foo2" "bar2" ]
--> [ IntegerAttribute "foo" 2, StringAttribute "foo2" "bar2" ]
replaceOrAddStringAttribute : String -> String -> List Attribute -> List Attribute
Replaces all StringAttributes that have the name provided in the list, or add it to the beginning of the list if no pre existing StringAttribute exists.
replaceOrAddStringAttribute "foo2" "bar3" [ BoolAttribute "foo" False, StringAttribute "foo2" "bar2" ]
--> [ BoolAttribute "foo" False, StringAttribute "foo2" "bar3" ]
