Class | Sass::Selector::Simple |
In: |
lib/sass/selector/simple.rb
|
Parent: | Object |
The abstract superclass for simple selectors (that is, those that don‘t compose multiple selectors).
filename | [RW] |
The name of the file in which this selector was declared, or `nil` if it
was not declared in a file (e.g. on stdin).
@return [String, nil] |
line | [RW] |
The line of the Sass template on which this
selector was declared.
@return [Fixnum] |
Checks equality between this and another object.
By default, this is based on the value of \{to_a}, so if that contains information irrelevant to the identity of the selector, this should be overridden.
@param other [Object] The object to test equality against @return [Boolean] Whether or not this is equal to `other`
Returns a hash code for this selector object.
By default, this is based on the value of \{to_a}, so if that contains information irrelevant to the identity of the selector, this should be overridden.
@return [Fixnum]
Returns a string representation of the node. This is basically the selector string.
@return [String]
Returns a representation of the node as an array of strings and potentially {Sass::Script::Node}s (if there‘s interpolation in the selector). When the interpolation is resolved and the strings are joined together, this will be the string representation of this node.
@return [Array<String, Sass::Script::Node>]
Unifies this selector with a {SimpleSequence}’s {SimpleSequence#members members array}, returning another `SimpleSequence` members array that matches both this selector and the input selector.
By default, this just appends this selector to the end of the array (or returns the original array if this selector already exists in it).
@param sels [Array<Simple>] A {SimpleSequence}’s {SimpleSequence#members members array} @return [Array<Simple>, nil] A {SimpleSequence} {SimpleSequence#members members array}
matching both `sels` and this selector, or `nil` if this is impossible (e.g. unifying `#foo` and `#bar`)
@raise [Sass::SyntaxError] If this selector cannot be unified.
This will only ever occur when a dynamic selector, such as {Parent} or {Interpolation}, is used in unification. Since these selectors should be resolved by the time extension and unification happen, this exception will only ever be raised as a result of programmer error
Unifies two namespaces, returning a namespace that works for both of them if possible.
@param ns1 [String, nil] The first namespace.
`nil` means none specified, e.g. `foo`. The empty string means no namespace specified, e.g. `|foo`. `"*"` means any namespace is allowed, e.g. `*|foo`.
@param ns2 [String, nil] The second namespace. See `ns1`. @return [Array(String or nil, Boolean)]
The first value is the unified namespace, or `nil` for no namespace. The second value is whether or not a namespace that works for both inputs could be found at all. If the second value is `false`, the first should be ignored.
