NAME

DESCRIPTION

This AST library provides the following classes:

Makefile::AST

The primary class for ASTs. Provides interface for node adding and querying, such as "add_implicit_rule", "apply_implicit_rules", "add_explicit_rule", "apply_explicit_rules", "add_var", "add_auto_var", "get_var", as well as lots of other utility functions, like method "eval_var_value" for computing the ultimate values of makefile variables, method "enter_pad" and "leave_pad" for local variable's scoping pad.

Makefile::AST::Rule::Base

This is the base class for the rule nodes in the AST. It has properties like "normal_prereqs", "order_prereqs", "commands", and "colon".

Makefile::AST::Rule

This class represents the de-sugared form of simple rules and implicite rules after application. It inherits from Makefile::AST::Rule::Base, and adds new properties "target" and "other_targets".

Makefile::AST::Rule::Implicit

This class represents the implicit rule nodes in the AST. It inherits from Makefile::AST::Rule::Base, and adds new properties "targets", "match_anything", and "is_terminal".

Makefile::AST::StemMatch

This class encapsulates the file pattern matching (file names containing "%") and stem substitution algorithms.

Makefile::AST::Variable

It represents the makefile variable nodes in the AST, including "name", "value", "flavor", and "origin".

Makefile::AST::Command

Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers "@", "-", "+", and etc.) as a whole.
