Given a tree, it creates a flattened one by merging the keys and binding the leaf values to the new keys.
Description
It also transforms camelCase names into kebab-case and substitutes ‘/’ by ‘-‘.
This is thought to be useful to generate CSS Custom Properties from a tree, although there’s nothing in the implementation of this function that requires that format.
For example, assuming the given prefix is ‘–wp’ and the token is ‘–‘, for this input tree:
{
'some/property': 'value',
'nestedProperty': {
'sub-property': 'value'
}
}it’ll return this output:
{
'--wp--some-property': 'value',
'--wp--nested-property--sub-property': 'value'
}Parameters
$treearrayrequired- Input tree to process.
$prefixstringoptional- Prefix to prepend to each variable.
Default:
'' $tokenstringoptional- Token to use between levels. Default
'--'.Default:
'--'
