I previously asked how to do this in Groovy. However, now I'm rewriting my app in Perl because of all the CPAN libraries.

Andy Lester Please look at using the WWW::Mechanize module for this. It will fetch your web pages for you, and then give you easy-to-work with lists of URLs. my $mech = WWW::Mechanize->new(); $mech->get( $some_url ); my @links = $mech-

Installing modules using Strawberry Perl

由 [亡魂溺海] 提交于 2019-11-26 19:01:54
问题 Until now I used ActiveState's ActivePerl, and used the ppm for installing modules. Last week I moved to Strawberry Perl, but I don't know how I should install modules using Strawberry Perl. What is some information on how module installation is done using Strawberry Perl or is there some link on how to install new modules? 回答1: You can still use ppm , but it is not recommended. Run CPAN client from the Strawberry Perl or Strawberry Perl (64-bit) , sub folder Tools , entry in the Start menu.

问题 Aside from trying perldoc <module name> individually for any CPAN module that takes my fancy or going through the file system and looking at the directories I have no idea what modules we have installed. What's the easiest way to just get a big list of every CPAN module installed? From the command line or otherwise. 回答1: This is answered in the Perl FAQ, the answer which can be quickly found with perldoc -q installed . In short, it comes down to using ExtUtils::Installed or using File::Find ,

Can a Perl script install its own CPAN dependencies?

由 删除回忆录丶 提交于 2019-11-26 16:18:43
问题 I have a Perl script that has two dependencies that exist in CPAN. What I'd like to do is have the script itself prompt the user to install the necessary dependencies so the script will run properly. If the user needs to enter in some kind of authentication to install the dependencies that's fine: what I'm trying to avoid is the following workflow: Run script -> Watch it fail -> Scour CPAN aimlessly -> Lynch the script writer Instead I'm hoping for something like: Run script -> Auto-download

Which cpan installer is the right one? (CPAN.pm/CPANPLUS/cpanminus)

由 喜欢而已 提交于 2019-11-26 12:08:14
问题 There are multiple installers for cpan modules available; I know of at least CPAN.pm (comes with perl,) CPANPLUS, and cpanminus. What is the difference between the three? What situations call for using one over the other? Are there other module installers I should know about? 回答1: CPAN.pm ( cpan ) is the original client. It comes with Perl, so you already have it. It has the most features. It has a lot of configuration options to customize the way it works, though virtually everyone accepts

How can I install a specific version of a set of Perl modules?

问题 I\'m tasked with replicating a production environment to create many test/sit environments. One of the things I need to do is build up Perl, with all the modules which have been installed (including internal and external modules) over the years. I could just use CPAN.pm autobundle, but this will result in the test environment having much newer versions of the external modules that production has. What is the easiest/best way to get and install (a lot of) version specific Perl modules. 回答1:

How do I tell CPAN to install all dependencies?

问题 How do I tell CPAN to install all dependencies? I tried setting these in cpan : cpan> o conf prerequisites_policy follow cpan> o conf commit I still had to answer \"y\" a couple of times (but fewer than before it feels like). Is there a way to get it to always go ahead and install? I want to make it unattended. It would seem that I want a flag to always trust CPAN to do the right thing, and if it suggests an answer I would like to follow it (always hit Enter when it asks something). 回答1: Here
