in reply to Perl syntax checking without `perl -c`

Went one step further and wrote Syntax::Check, which comes with its own syncheck binary:

$ syncheck t/data/test.pl 

t/data/test.pl syntax OK

[download]

Add --verbose|-v to get output of the name of the temporary lib dir and all modules it skipped. Use --keep|-k to keep the temporary directory around after program execution.

Uses PPI, so if that's not installed, installation of this distribution may take a bit of time.

Re^2: Perl syntax checking without `perl -c` [Syntax::Check]

    I had a look in both the POD and the source: couldn't see anything that dealt with "Can't use bareword ("syntactic_sugar") ..." which I first mentioned in "Re: Perl syntax checking without `perl -c` [general reply to all]".

    I checked and found that I did have PPI so I thought I'd install it. More than 45 minutes later, and it's still installing (I have neither a slow machine nor a slow internet connection). The issue seems to involve the "Module::Installed::Tiny dependency tree" — that doesn't look very Tiny to me.

    I have to go back to $work now. The installation is still running. I can't wait for it any longer.

    Update: I checked back periodically. It looks like the installation hung after about 1hr 10mins.

      Sheesh! I never noticed that. The deps are ALL related to test prereqs.

      I liked the premise of the distribution, so I wrote my own. Module::Installed. It not only checks single modules, but I added a function that will list all includes in a file and whether or not they are installed or not. There are no non-core deps. PPI is required to use the includes_installed() function, but we load it dynamically only if it's available:

      use warnings;
use strict;

use Data::Dumper;
use Module::Installed qw(module_installed includes_installed);

my $module = 'PPI';
my $file = '/home/spek/repos/module-installed/t/data/test.pl';

my $statement = module_installed($module)
    ? "is installed"
    : "isn't installed";

print "$module $statement\n\n";

print "Checking includes in file $file\n\n";

my $includes = includes_installed($file);

print Dumper $includes;

      Output:

      PPI is installed

      I just finished a very large Perl project that I landed a little while ago. It's nice to be back in the Perl mindset, hammering out all manner of weird stuff. I'll take a look at the "bareword" issue in Syntax::Check later this afternoon.

      Update: Holy crap, I just realized I've hit the 50 mark in published CPAN distributions!
