NAME

File::ShouldUpdate - should files be rebuilt?

VERSION

version 0.2.0

SYNOPSIS

    use File::ShouldUpdate qw/ should_update should_update_multi /;

    if (should_update("output.html", ":", "in.tt2", "data.sqlite"))
    {
        system("./my-gen-html");
    }

    if (should_update_multi(["output.html", "about.html", "contact.html"], ":", ["in.tt2", "data.sqlite"]))
    {
        system("./my-gen-html-multi");
    }

DESCRIPTION

This module provides should_update() which can be used to determine if files should be updated based on the mtime timestamps of their dependencies. It avoids confusing between target and dependencies by using syntactic sugar of the familiar makefile rules ( https://en.wikipedia.org/wiki/Make_(software) ).

FUNCTIONS

my $verdict = should_update($target, ":", @deps);

Should $target be updated if it doesn't exist or older than any of the deps.

my $verdict = should_update_multi([@targets], ":", [@deps]);

Should @targets be updated if some of them do not exist or any of them are older than any of the deps.

Note that you must pass array references.

[Added in version 0.2.0.]
