ExtUtils::PerlPP 1.2219

ExtUtils::PerlPP is a Perl Preprocessor. SYNOPSIS use ExtUtils::PerlPP; my $config = { version => $VERSION, driver => $DRIVER }; # The long and winding road ... my $self = ExtUtils::PerlPP->new(); $self->{in_fh} = IO::File->new(file.PL, r); $self->{out_fh} = IO::File->new(file, w); $self->{config} = $self->parse(); # And now a short cut for the same: ppp(file.PL, file, $config); Perls installation suite, ExtUtils::MakeMaker, contains a mechanism for installing preparsed files, so-called PL files: If the MakeMaker utility detects files with the extension .PL then these files are executed by make, usually creating a file of the same name, except the .PL extension. Writing these PL files is usually always the same, for example a typical .PL file might look like this: my $script = <<SCRIPT; ... # True file following here SCRIPT # Modify variable $script, depending on configuration, local # site or whatever ... if (!open(FILE, ">file") || !(print FILE $script) || !close(FILE)) { die "Cannot write file: $!"; } But in essence, what else is this than a Perl preprocessor? Traditionally you have to write such a Perl preprocessor for yourself all the time, although I have found that they always do the same, for example: - Fix defaults, for example installation paths. - Including or excluding code sections. It is a matter of taste whether one likes to see if ($] < 5.003) { # Thirty lines of code following here ... } else { # A single line of code ... } when already using Perl 5.005. I dont..
