# ABSTRACT: command line app runner for Reply
use Getopt::Long 'GetOptionsFromArray';
use Reply;
use Reply::Config;
=head1 SYNOPSIS
use Reply::App;
exit(Reply::App->new->run(@ARGV));
=head1 DESCRIPTION
This module encapsulates the various bits of functionality related to running
L<Reply> as a command line application.
=cut
=method new
Returns a new Reply::App instance. Takes no arguments.
=cut
sub new { bless {}, shift }
=method run(@argv)
Parses the argument list given (typically from @ARGV), along with the user's configuration file, and attempts to start a Reply shell. A default configuration file will be generated for the user if none exists.
=cut
sub run {
my $self = shift;
my @argv = @_;
my $cfgfile = '.replyrc';
my $exitcode;
my $parsed = GetOptionsFromArray(
\@argv,
'cfg:s' => \$cfgfile,
'version' => sub { $exitcode = 0; version() },
'help' => sub { $exitcode = 0; usage() },
);
if (!$parsed) {
usage(1);
$exitcode = 1;
}
return $exitcode if defined $exitcode;
my $cfg = Reply::Config->new(file => $cfgfile);
my %args = (config => $cfg);
my $file = $cfg->file;
if (!-e $file) {
print("$file not found. Generating a default...\n");
if (open my $fh, '>', $file) {
my $contents = do {
local $/;
<DATA>
};
$contents =~ s/use 5.XXX/use $]/;
print $fh $contents;
close $fh;
}
else {
warn "Couldn't write to $file";
%args = ();
}
}
Reply->new(%args)->run;
return 0;
}
=method usage($exitcode)
Prints usage information to the screen. If C<$exitcode> is 0, it will be
printed to C<STDOUT>, otherwise it will be printed to C<STDERR>.
=cut
sub usage {
my $fh = $_[0] ? *STDERR : *STDOUT;
print $fh " reply [--version] [--help] [--cfg file]\n";
}
=method version($exitcode)
Prints version information to the screen. If C<$exitcode> is 0, it will be
printed to C<STDOUT>, otherwise it will be printed to C<STDERR>.
=cut
sub version {
my $fh = $_[0] ? *STDERR : *STDOUT;
print $fh "Reply version $Reply::VERSION\n";
}
