Makefile::AST::Evaluator(3pm) User Contributed Perl Documentation Makefile::AST::Evaluator(3pm)
NAME
Makefile::AST::Evaluator - Evaluator and runtime for Makefile::AST instances
SYNOPSIS
use Makefile::AST::Evaluator;
$Makefile::AST::Evaluator::JustPrint = 0;
$Makefile::AST::Evaluator::Quiet = 1;
$Makefile::AST::Evaluator::IgnoreErrors = 1;
$Makefile::AST::Evaluator::AlwaysMake = 1;
$Makefile::AST::Evaluator::Question = 1;
# $ast is a Makefile::AST instance:
my $eval = Makefile::AST::Evaluator->new($ast);
Makefile::AST::Evaluator->add_trigger(
firing_rule => sub {
my ($self, $rule, $ast_cmds) = @_;
my $target = $rule->target;
my $colon = $rule->colon;
my @normal_prereqs = @{ $rule->normal_prereqs };
# ...
}
);
$eval->set_required_target($user_makefile)
$eval->make($goal);
DESCRIPTION
This module implementes an evaluator or a runtime for makefile ASTs represented by Makefile::AST instances.
It "executes" the specified GNU make AST by the GNU makefile semantics. Note that, "execution" not necessarily mean building a project tree
by firing makefile rule commands. Actually you can defining your own triggers by calling the add_trigger method. (See the "SYNOPSIS" for
examples.) In other words, you can do more interesting things like plotting the call path tree of a Makefile using Graphviz, or translating
the original makefile to another form (like what the makesimple script does).
It's worth mentioning that, most of the construction algorithm for topological graph s (including implicit rule application) have already
been implemented in Makefile::AST and its child node classes.
CONFIGURE VARIABLES
This module provides several package variables (i.e. static class variables) for controlling the behavior of the evaluator.
Particularly the user needs to set the $AlwaysMake variable to true and $Question to true, if she wants to use the evaluator to do special
tasks like plotting dependency graphs and translating GNU makefiles to other format.
Setting $AlwaysMake to true will force the evaluator to ignore the timestamps of external files appeared in the makefiles while setting
$Question to true will prevent the evaluator from executing the shell commands specified in the makefile rules.
Here's the detailed listing for all the config variables:
$Question
This variable corresponds to the command-line option "-q" or <--question> in GNU make. Its purpose is to make the evaluator enter the
"questioning mode", i.e., a mode in which "make" will never try executing rule commands unless it has to, "and" echoing is suppressed
at the same time.
$AlwaysMake
This variable corresponds to the command-line option "-B" or "--always-make". It forces re-constructing all the rule's targets related
to the goal, ignoring the timestamp or existence of targets' dependencies.
$Quiet
It corresponds to GNU make's command-line option "-s", "--silent", or "--quiet". Its effect is to cancel the echoing of shell commands
being executed.
$JustPrint
This variable corresponds to GNU make's command line option "-n", "--just-print", "--dry-run", or "--recon". Its effect is to print out
the shell commands requiring execution but without actually executing them.
$IgnoreErrors
This variable corresponds to GNU make's command line option "-i" or "--ignore-errors"ieXXIt's used to ignore the errors of shell
commands being executed during the make process. The default behavior is quitting as soon as a shell command without the "-" modifier
fails.
CLASS TRIGGERS
The "make_by_rule" method of this class defines a trigger named "firing_rule" via the Class::Trait module. Everytime the "make_by_rule"
method reaches the trigger point, it will invoke the user's processing handler with the following three arguments: the self object, the
Makefile::AST::Rule object, and the corresponding "Makefile::AST::Command" object in the context.
By registering his own processing handlers for the "firing_rule" trigger, the user's code can reuse the evaluator to do his own cool things
without traversing the makefile ASTs himself.
See the "SYNOPSIS" for code examples.
