NAME

Makefile::AST - AST for (GNU) makefiles

CONTENTS

DESCRIPTION

The structure of this (GNU) makefile AST is designed based on GNU make’s data base listing output produced by --print-data-base.

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.

LIMITATIONS AND TODO

Adding support for other flavors’ makes into this AST library should make a huge amount of sense. The most interesting candiate is Microsoft’s NMAKE.
