Programming :: Perl - Store And Access An Array In A Hash Of Hashes?
Jul 7, 2010I am in need of some syntax help. I'm trying to figure out how to store and retrieve an array out of a hash of hashes. For this example, I'm trying to access the city list for a particular state for a particular country. I understand I could do a join and split on the hash key to combine Country and State, but trying to keep things separated.The code I have gets in all the information for the Countries, and states, and gets the list of cities together, no problem. I store all the city names in an array, then make an anonymous pointer to the array for the hash, like this - $MY_CITIES{$COUNTRY}{$STATE} = [@CITIES]I believe that syntax is correct, or is it? What I'd like to do is I need to cycle through every hash to find if a city exists or not. If it exists in 3 states, then it should print 3 times. Here is the code block to search -
Code:
for $COUNTRY (@LIST_OF_COUNTRIES) {
for $STATE ( keys %MY_CITIES{$COUNTRY){$STATE} ) {

Software :: Perl Installation In Custom Location?
May 11, 2011I have an requirement of installing perl in custom location (NFS share that will be mounted on many machines).e.g,suppose '/usr/perly' is the NFS share, perl will be invoked as /usr/perly/bin/perl I require all the libraries to be created on the same share so that no local libraries are referred. Also, I need hundreds of modules installed in the same location.How do I do it with CPAN method?

May 19, 2011I have installed perl5.12.3 in a custom location, ( a NFS share). I have all the libraries created in the same location. This was an attempt not to disturb existing version of perl. I have succeeded doing this.Now, I need to install around 200 perl modules. I tried Bundle option in CPAN shell, it somehow did not work. Does anyone here know off any other better method of installing multiple perl modules. How do I use CPANPLUS to install all the modules. What changes do I make to Config.pm considering custom location of perl installation I have done.

Programming :: Association Lists Are Faster Than Hash Tables?
Jun 13, 2011I'm writing an interpreter and it used simple association lists for mapping varaible names to their values. Here's the code:
Code:
#include "assoc_array.hpp"
#include <string.h>
using namespace LANG_NAMESPACE;
[code]....
I thought that I would replace it with a hash table to increase performance. Note that I decided to store linked lists in the buckets instead of the actual values, in case the hash function outputs the same index for multiple variable names:
Code:
#include "hash_table.hpp"
#include "assoc_array.hpp"
#include <string.h>
[code]....
It runs in about 0.333 seconds on my machine. Since I'm using git version control, I decided to bring back the old version that used association lists. To my amazement, it ran 3 times faster, completing in 0.116 seconds! Is my hash table implementaion really that bad, or is this a really poor benchmark (and real-world code actually will be faster using the hash table)?
Programming :: Store Executable Code In The Value Part Of A Hash?
May 28, 2010I was reading about Ruby code blocks, but it's all a bit hazy.My questions:1. Can you store executable code in the value part of a hash (err...associative array)2. If you did, how would you call the code?3. If you executed this stored code, would it be possible when doing soto pass in an object to the code that it could use?

Programming :: Hashing The Components Of An Tcp Session To Assign/locate The Session In A Hash Table Bucket?
Nov 10, 2010I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

View 8 Replies View RelatedProgramming :: MP3 - Tag And Perl Script
Mar 27, 2011I am a newbie on linux and just searching everything about perl scripting and modules nearly 3-4 days. I need a perl script but one of not easy to find on searching google. Okay now I need a perl script which create or recreate (edit) id3 tags (artist, comment, album, year, cover) of mp3 files stored on my linux centos server. I installed MP3::Tag version 1.13 pearl module to my server. I Searched tutorials about how to use it, finally I get through reading id3 tag of mp3 file but not achieve to modify it or create a new id3tag.
These are the details:
I have a mp3 file called 1.mp3 this script will process that '1.mp3' file read its id3tag if there is one, than modify or create id3tag for it by my fix artist name for example:
'1.mp3' files id3 tag details are like this
Artist: Dj xx
Year:2010
Title:yyyyy
Comment:eerwer
Cover: x.jpg
Now via this perl script which uses MP3::TAG I will change it's
artist as YYY
Title:ttt
Comment:cool
Cover:t.jpg
these are gonna be my fixed values. I mean all '1.mp3' file will have same artist based on script value.
The reason of this script is I will share Dj podcasts on my server and Dj's would have upload their mp3's which has got different id3 tags and cover pics. etc. I want to create more organized podcasts of them by the way I would trigger this perl script via Cronjob.
