Returns JavaScript's null value if this is sassNull, and returns
this otherwise.
This value as a list.
All SassScript values can be used as lists. Maps count as lists of pairs, and all other values count as single-value lists.
An immutable List from the immutable
package.
Whether this value as a list has brackets.
All SassScript values can be used as lists. Maps count as lists of pairs, and all other values count as single-value lists.
Whether the value counts as true in an @if statement and other
contexts.
The separator for this value as a list.
All SassScript values can be used as lists. Maps count as lists of pairs, and all other values count as single-value lists.
Throws if this isn't a SassBoolean.
Heads up! Functions should generally use isTruthy rather than requiring a literal boolean.
Optionalname: stringThe name of the function argument this came from (without
the $) if it came from an argument. Used for error reporting.
Throws if this isn't a SassCalculation.
Optionalname: stringThe name of the function argument this came from (without
the $) if it came from an argument. Used for error reporting.
Throws if this isn't a SassFunction.
Optionalname: stringThe name of the function argument this came from (without
the $) if it came from an argument. Used for error reporting.
Throws if this isn't a SassNumber.
Optionalname: stringThe name of the function argument this came from (without
the $) if it came from an argument. Used for error reporting.
Throws if this isn't a SassString.
Optionalname: stringThe name of the function argument this came from (without
the $) if it came from an argument. Used for error reporting.
Returns the value at index index in this value as a list, or undefined
if index isn't valid for this list.
All SassScript values can be used as lists. Maps count as lists of pairs, and all other values count as single-value lists.
This is a shorthand for this.asList.get(index), although it may be more
efficient in some cases.
Heads up! This method uses the same indexing conventions as the
immutable package: unlike Sass the index of the first element is 0, but
like Sass negative numbers index from the end of the list.
Returns a hash code that can be used to store this in a hash map.
Converts sassIndex into a JavaScript-style index into the list returned
by asList.
Sass indexes are one-based, while JavaScript indexes are zero-based. Sass indexes may also be negative in order to index from the end of the list.
The Sass-style index into this as a list.
Optionalname: stringThe name of the function argument sassIndex came from
(without the $) if it came from an argument. Used for error reporting.
Error If sassIndex isn't a number, if that number isn't an
integer, or if that integer isn't a valid index for asList.
Returns this as a map if it counts as one (empty lists count as empty
maps) or null if it doesn't.
