Provides interface for node adding and querying, such as \f(CW\*(C`add_implicit_rule\*(C'\fR, \f(CW\*(C`apply_implicit_rules\*(C'\fR, \f(CW\*(C`add_explicit_rule\*(C'\fR, \f(CW\*(C`apply_explicit_rules\*(C'\fR, \f(CW\*(C`add_var\*(C'\fR, \f(CW\*(C`add_auto_var\*(C'\fR, \f(CW\*(C`get_var\*(C'\fR, as well as lots of other utility functions, like method \f(CW\*(C`eval_var_value\*(C'\fR for computing the ultimate values of makefile variables, method \f(CW\*(C`enter_pad\*(C'\fR and \f(CW\*(C`leave_pad\*(C'\fR for local variable's scoping pad. .IP "Makefile::AST::Rule::Base" 4 .IX Item "Makefile::AST::Rule::Base" This is the base class for the rule nodes in the \s-1AST\s0. It has properties like \f(CW\*(C`normal_prereqs\*(C'\fR, \f(CW\*(C`order_prereqs\*(C'\fR, \f(CW\*(C`commands\*(C'\fR, and \f(CW\*(C`colon\*(C'\fR. .IP "Makefile::AST::Rule" 4 .IX Item "Makefile::AST::Rule" This class represents the de-sugared form of simple rules and implicite rules \fIafter\fR application. It inherits from Makefile::AST::Rule::Base, and adds new properties \f(CW\*(C`target\*(C'\fR and \f(CW\*(C`other_targets\*(C'\fR. .IP "Makefile::AST::Rule::Implicit" 4 .IX Item "Makefile::AST::Rule::Implicit" This class represents the implicit rule nodes in the \s-1AST\s0. It inherits from Makefile::AST::Rule::Base, and adds new properties \f(CW\*(C`targets\*(C'\fR, \f(CW\*(C`match_anything\*(C'\fR, and \f(CW\*(C`is_terminal\*(C'\fR. .IP "Makefile::AST::StemMatch" 4 .IX Item "Makefile::AST::StemMatch" This class encapsulates the file pattern matching (file names containing \f(CW\*(C`%\*(C'\fR) and stem substitution algorithms. .IP "Makefile::AST::Variable" 4 .IX Item "Makefile::AST::Variable" It represents the makefile variable nodes in the \s-1AST\s0, including \f(CW\*(C`name\*(C'\fR, \f(CW\*(C`value\*(C'\fR, \f(CW\*(C`flavor\*(C'\fR, and \f(CW\*(C`origin\*(C'\fR. .IP "Makefile::AST::Command" 4 .IX Item "Makefile::AST::Command" Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers \f(CW\*(C`@\*(C'\fR, \f(CW\*(C`\-\*(C'\fR, \f(CW\*(C`+\*(C'\fR, and etc.) as a whole. .SH "LIMITATIONS AND TODO" .IX Header "LIMITATIONS AND TODO" Adding support for other flavors' makes into this \s-1AST\s0 library should make a huge amount of sense.
