ordered hashes

[brendag4]

How do I get a hash to output data in the order the data was put in?

I have been trying to look it up... I see that Tie is used.. but there are a lot of different types... and one thing I read said it was not standard. (Tie::IxHash)

How do I find out if I have it, or the server has it?

What is the best way to get what is stored in a hash in the order you inserted it in?

You can always find out if a module is installed by doing this at the command line -

perl -e "use Tie::IxHash"
perl -e "use CGI"

If nothing is output, then the module is available.

Tie::IxHash is the best way to do what you want. It isn't installed on SEVEN. You could always install it yourself. Instead of - perl Makefile.PL, you would do a perl Makefile.PL PREFIX=/some/directory, and then just add a uselib '/some/directory'; to your code.

Actually, for Tie::IxHash, you don't even really have to do the -
perl Makefile.PL
make
make install

Just download it, tar xvfpz it, go into the lib directory and do cp -pr Tie to what ever directory you want to keep modules in. Then just add a use lib to your script.

While on the subject of perl modules, does anyone know a way to get around the use lib in a cgi script? Is there a way to set the env var PERL5LIB so that it will be used by a cgi script?

Umm... your post was way over my head :-)

I am just using the Perl I downloaded that was already all made up. (Whatever you call that.)

I am not on FQ yet... I am using HyperMart and Virtual Ave.

I don't think it is possible to get to the shell on HyperMart. I don't know about Virtual Ave.

I am not on FQ yet...

Tsk. Tsk. Tsk.  

If you were, then I probably would have added it to our perl module core...

When I get a paid site it will definitely be with FQ :-)

Think I am finally getting near the finishing stages of my script...
