RulesTree

RulesTree[data{rule₁,rule₂,…}]

gives a tree whose root contains data and that has children specified by the rule_i.

Details

RulesTree gives a Tree object.
The children of RulesTree[data{rule₁,rule₂,…}] are given by {RulesTree[rule₁],RulesTree[rule₂],…}.
RulesTree[data] for data not of the form …{…} is equivalent to RulesTree[data{}]. »

Construct a tree with one node:

Specify a list of children:

RulesTree constructs a tree associated with the given rules:

Use TreeRules on the result to recover the original rules:

RulesTree can be computed with NestTree:

RulesTree[expr{}] is generally equivalent to RulesTree[expr]:

However, the empty list is necessary to specify a tree with data of the form lhs{e₁,e₂,…}:

Without the empty list, this would be treated as a tree whose root contains lhs with children {RulesTree[e₁],RulesTree[e₂],…}:
