RE: one liner for removing string from an element of string array
Ron, Shlomi, I realized I haven’t thanked you. Thanks, Regards, Satya P.S : I am not a fan of one liners but as a beginner of perl there are many others out there who want to see the power of perl to do that in one line, it is just a way to be a fan of the language and then things get improved automatically since you love it. -Original Message- From: Shlomi Fish [mailto:shlo...@shlomifish.org] Sent: 13 July 2012 17:00 To: Nemana, Satya Cc: beginners@perl.org Subject: Re: one liner for removing string from an element of string array Hi Satya, On Fri, 13 Jul 2012 15:38:20 + Nemana, Satya snem...@sonusnet.com wrote: Hi I have written a small program like this to just print file2 from the second element of the array by removing the .template from the entry (the name file2 can change and can be longer or shorter) use strict; use Data::Dumper; use warnings; my @templates = ( /a/b/c/d/e/f/file1.template, /a/b/c/d/e/f/file2.template ); my @tokens=split( /\//, $templates[1]); print(\n.substr($tokens[$#tokens],0,-9)); However I want this to be more efficient and want to do this in a single line as I have to do this several times.

Storage using Storable
Hi , I have a multiple processes which are modifying hash of hash of array. For multiprocessing I am using Parallel::ForkManager The requirement is I set Max processes to say 5. Each process is fired by the script and max 5 parallel process runs and it performs some actions on a complex datastructure like each process after performing a task based on success moves user entry from pending hash key to completed hash key. Now this task needs to be run on around 10K users and I need not run this more than 1 hr after which I need to store the state disc which I can revisit and start from point where I left. I am planning to use Storable module for storing and retrieve later. My question is do I need to implement locks on write operation as multiple Procs will be writing data to same complex datastructure ? or just using store() in each process will take care of simultaneous writes ? Any pointers to some code will be helpful. Thanks and Regards, Puneet

suggestions for perl program to make excel graph out from top output
Gurus, I want to write a perl program that captures top output in linux and makes nice graphs out of them(Microsoft excel) Are there ready to use modules for this which will help in writing the program? Any suggestions for inspirations? Search in cpan for top is resulting in a lot of results, most of which are irrelevant, are there smarter ways to search?

Re: Perl MVC framework
Chris, an MVC Framework is just a design approach to help manage your code, so you don't really need to use Catalyst or Dancer, or anyone else's framework. Instead, you can easily emulate what you like best about any of them when setting up an app structure and design one that you can be most productive with. I thought I'd mention that you always have that option too.

I agree, that's just a messy approach. I've mentioned before that there ought to be Perl runtime for the client side, but that seems to be a pretty stupid idea because no one else liked it ;) I still don't use sql in the apps I've made. I haven't run into a desperate need for it. The thing I think many developers ignore is that if you know where the data you want to use resides (the path to the file), you really can't get it much faster than opening and reading the file (using the system B-tree). I don't use Template Toolkit. To me, calls to my perl code that are embedded in HTML is just the opposite of putting html in my perl code. It adds complexity that I don't want. I use HTML Template instead. It's simple and straight forward. I struggle with JS, and CSS, but I'm getting a little better with both. I recently got Dreamweaver 5.5 and that's helped a lot with applying CSS. I've been using the Prototype JS libraries for a bit now, and they're pretty easy to figure out, but I still struggle and fumble my way along with them and JS in general. There is a lot to be said for keeping things simple. If you're one guy coding perl, js, css, and html for an app, you've already got too much to do.

What is the best Perl MVC framework for someone to learn that has minimal web development back ground, but is intermediate with Perl scripting? Just a note - at the last YAPC::NA there were a number of good review sessions, for mojolicious, dancer etc. I hope there up here already: http://www.youtube.com/yapcna otherwise, they will be soon. -- a Andy Bach, afb...@gmail.com 608 658-1890 cell 608 261-5738 wk -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
