Terminal tells me that there's an issue with the code

[willfbren]

I've installed all the proper modules for perl and still get this issue when trying to parse the beatport release.

$ perl beatport.pl "http://www.beatport.com/release/low-key-ep/131754"
defined(@array) is deprecated at beatport.pl line 8.
    (Maybe you should just omit the defined()?)
malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "(end of string)") at beatport.pl line 51.

Any suggestions?

[VxJasonxV]

Pull updates. defined isn't located in the script at all anymore.

I just tested it against the current version, and it works fine. You may be running an older commit.

[willfbren]

Great thank you! Was running against older version.

This is the error I get now: html.query error - The query does not contain any elements

Sorry if this is basic stuff, I'm learning slowly.

[willfbren]

Any ideas?

That is the error when passing a URL thru the parser.

[VxJasonxV]

That's happening still when running the perl script? Like I said initially, I passed your exact command line in and had no issues whatsoever. My web browser opens with the submission button, and there is no output on the command line, indicating a successful execution.

I suspect that you're not actually getting the Beatport web page when you run it, but I wouldn't have the slightest idea why.

Since I don't really have any debugging already implemented, we can probably use the perl debugger to figure this out:

Run perl -d beatport.pl "http://www.beatport.com/release/low-key-ep/131754"

You should see the following output:

Loading DB routines from perl5db.pl version 1.37
Editor support available.

Enter h or 'h h' for help, or 'man perldebug' for more help.

main::(beatport.pl:32): my $URI = shift @ARGV unless not @ARGV;
  DB<1>

Here, type c 39 and press enter. You'll get a single line back:

  DB<1> c 39
main::(beatport.pl:39): my $c = Query( text => $content, 'div.release-detail' );
  DB<2>

Here, you can run x $content and copy the output. There will be a lot. Hopefully it will be pretty obvious (to me) whether or not it's the webpage we're looking for.

[willfbren]

Thank you man. I'll run that in the morning and let you know what I get.

Thanks for all your help. I really like perl and beets and I'm just trying to learn more about it. If you have any sites I should check out that would futher my understanding/tutorials, please pass those along. I want to learn as much as I can.

So this is odd... I get a webpage but for some reason it looks like it's the checkout page on Beatport?

I was talking to another user and the only thing we noticed different in our setups were when he runs: which perl his output is: /opt/local/bin/perl

When I run which perl my output is /usr/bin/perl

We were checking to make sure my perl version was up-to-date I believe. Thanks for your help.

It's definitely not the checkout page. There's tons of information pre-loaded in order to get AJAX to work for them. Think of it this way: Beatport's site doesn't use frames, but the audio player continues to work while you browse around the site. This is accomplished by having a ton of information available in every page, and updating only the necessary pieces of the site as you browse from page to page.

Your friend installed perl via some third party system. Macports, Homebrew, or something else like those, where you're using the built-in system version. If you were able to install the modules, then I don't think a version discrepancy is to blame here.

I'm thinking about the best way to try and debug this, which more than likely means adding new code to find parts of the page and report them. Might mean learning more about the debugger. We'll see.

[VxJasonxV]

It's local to your machine, but that doesn't mean it's not a bug. It can be both, the two are not mutually exclusive. Version numbers and interactivity and all that stuff is hard.

[willfbren]

Figured the issue out. Did not have perl installed at the user level. Only at the root. Not sure why it couldn't run at root, but as soon as all packages were installed at user level, works perfectly.

Thanks for the parser!

[VxJasonxV]

I don't entirely understand that explanation. If you were missing perl, the script wouldn't run at all, running perl would say "command not found". If you were missing HTML::Query, the script wouldn't have run at all and you would have gotten an error loading that package. But both happened, perl ran and you got a very specific message from HTML::Query indicating it functioned, but couldn't fulfill the request.

Can you tell me exactly what you did to fix it?

[willfbren]

Sorry for the confusion. Not sure of all the proper lingo.

What I found fixed it was this:

I had originally installed perl and all the modules at ~HD/Library/perl. (I'm on a Mac).

That is when I was getting the errors. First, because I didn't pull the latest version then the HTML query error that nothing was defined. I do have HTML::Query installed in that library though, so I'm not sure why I was getting that error.

After you mentioned Macports, I did some research and installed perl using Macports. This time it installed at ~HD/Users/William/perl. This is what I meant by "user level". Made sure I had all the proper modules installed and voila. Worked like a charm.

I'm very new to command line languages and the proper terms. Let me know if this explanation makes better sense.
