  • Parsing command line options in Perl

    - by Jay Gridley
    Hi guys, I am parsing command line options in Perl using Getopt::Long. I am forced to use prefix - (one dash) for short commands (-s) and -- (double dash) for long commands (ex. --input=file), but problem is, that there is one special option (-r=) so it is long option for its requirement for argument, but it has to have one dash (-) prefix not double dash (--) like other long options. Is possible to setup Getopt::Long to accept these?

  • Perl Term::ReadKey don't wait for newline

    - by tim
    In a perl script, I'm trying to accept input without blocking and without echoing the characters entered (The script is producing output and I want to have 'hotkeys' to alter its behaviour). I got as far as using use Term::ReadKey; ReadMode( "cbreak", STDIN ); if($input = ReadKey($pause_time, STDIN)){ #process input } But once the user types anything then the script stops until a newline is entered. I'd like the input to be processed per-character, without waiting for a newline.

  • Perl like regex in Python

    - by anansi
    In Perl I would do something like this for taking different fields in a regexp, separating different fields by () and getting them using $ foreach $line (@lines) { $line =~ m/(.*?):([^-]*)-(.*)/; $field_1 = $1 $field_2 = $2 $field_3 = $3 } How could I do something like this in Python?

  • Architecting Python application consisting of many small scripts

    - by Duke Dougal
    I am building an application which, at the moment, consists of many small Python scripts. Each Python script processes items from one Amazon SQS queue. Emails come into an initial queue and are processed by a script and typically the script will do a small unit of processing (for example, parse email and store some database fields), then an item will be placed on the next queue for further processing, until eventually the email has finished going through the various scripts and queues. What I like about this approach is that it is very loosely coupled. However, I'm not sure how I should implement live. Should I make each script a daemon which is constantly polling it's inbound queue for things to do? Or should there be some overarching orchestration program or process? Or maybe I should not have lots of small Python scripts but one large application? Specific questions: How should I run each of these scripts - as a daemon with some sort or restart monitor to restart them in case they stop for any reason? If yes, should I have some program which orchestrates this? Or is the idea of many small script not a good one, would it make more sense to have a larger python program which contains all the functionality and does all the queue polling and execution of functionality for each queue? What is the current preferred approach to daemonising Python scripts? Broadly I would welcome any comments or opinions on any aspect of this. thanks

  • Pros and cons of hosted scripts

    - by P.Brian.Mackey
    I have seen some developers use hosted scripts to link their libraries. cdn.jquerytools.org is one example. I have also seen people complain that a hosted script link has been hijacked. How safe is using hosted scripts in reality? Are the scripts automatically updated? For example, if jQuery 5 goes to 6 do I automatically get version 6 or do I need to update my link? I also see that Google has a large set of these scripts setup for hosting. What are the pros and cons?

  • What conventions or frameworks exist for MVVM in Perl?

    - by Will Sheppard
    We're using Catalyst to render lots of webforms in what will become a large application. I don't like the way all the form data is confusingly into a big hash in the Controller, before being passed to the template. It seems jumbled up and messy for the template. I'm sure there are real disadvantages that I haven't described properly... Are there? One solution is to just decide on a convention for the hash, e.g.: { defaults => { type => ['a', 'b', 'c'] }, input => { type => 'a' }, output => { message => "2 widgets found of type a", widgets => [ 'foo', 'bar' ] } } Another way is to store the page/form data as attributes in a class (a ViewModel?), and pass a whole object to the template, which it could use like this: <p class="message">[% model.message %]<p> [% FOREACH widget IN model.widgets %] Which way is more flexible for large applications? Are there any other solutions or existing Catalyst-compatible frameworks?

  • Fast and Free; SQL Scripts Manager's Script Generator

    When William produced his second article on the free tool 'SQL Scripts Manager', revealing that it worked just as well with PowerShell and Python scripts as it does with TSQL, he thought that would be the end of the series. Oh no; in response to feedback, comes a small add-in called 'Script Generator' that makes a big difference to the speed of developing and producing new scripts.

  • How to profile a Perl + FastCGi + StarRunner web program?

    - by Paul Tomblin
    I've written an extension to RequestTracker for a client, but he says the performance isn't good enough. I'd like to do some profiling, but I'm not sure how to connect up a profiler (say NYTProf, for example)? I tried what the man page says and put PerlModule Devel::NYTProf::Apache in my apache config, but all I get in the results are Apache2:XSLoader, Devel::NYTProf::Apache and ModPerl::Util modules in the results, and neither my own nor RT's modules.

    I have several thousand objects with string property in the format of "yyyy-MM-ddTHH:mm:ssZ". I want to sort these objects ordered by time. Is there any useful packages or scripts for this ? (currently I'm just comparing individual numeric values and it seems it's not very efficient and neat)

    - by zedoo
    Hi I am getting started with Test::More, already have a few .t test scripts. Now I'd like to define a function that will only be used for the tests, but accross different .t files. Where's the best place to put such a function? Define another .t without any tests and require it where needed? (As a sidenote I use the module structure created by Module::Starter)
