# The idea here is to take the benefits of make (highly visible code,
# excellent dependency tracking) and combine them with Module::Build
# (portable, OO overrides).

# This is all valid Perl code (with a small source filter)
# To use, you run the schmakefile directly.
# perl schmake
# perl schmake test
# perl schmake install
# Some calculated data may be cached to improve performance.

# Minimal source filter.  Turns this into an anon subclass and turms
# "target : dep" into methods.
use Schmake;

# ******Features to consider******
# Equivalent to make -n
# Ignore return status (is eval enough?)
# Don't echo this line (possibly default)
# Kill the target if a command fails
# Equivalent to $? and $* and the like
# Introspection of the dependency tree
# Self-hosting
# Makefile.PL and Build.PL and autoconf emulation
# Better user diagnostics for things like missing deps

# Module::Install style declarations of metadata
name         "Foo::Bar";
perl_version "5.10.1";
requires     "perl5i";
external_dep "...";  # libraries, binaries, databases


# Execute before the default install
install :< dep1 dep2
    ...

# Execute after the default install target
install :: conf/my.conf conf/other.conf
    install($_, { type => "config" }) for @_;
    say <<END;
    Write it from here.
    END
    run(...a shell command...);

# Execute this after the default install as well
install :: sbin/foo sbin/bar
    install($_, { type => "sbin" }) for @_; 

# Completely override the default install target
install : dep1 dep2
    ...

# Perfectly valid Perl code
say "This is the end";
