I take it that MIDI::ALSA  (https://metacpan.org/pod/MIDI::ALSA) has little

What I did in a project is having the main functionality written in C,
but using Perl for things that could be handy like parsing a config file
(lot of text, regex, etc.) or calling outside script that could be
written independently from the main code.

Best luck,

Many thanks.  I am glad I asked the question but it has taken me
some time to digest your answer as I wasn't familiar with the
term FFI so, after exercising duckduckgo, I now know those
letters stand for Foreign Function Interface which makes perfect
sense based on what needs to be done.  Unfortunately, FFI's are
usually used by higher-level languages to take advantage of the
capabilities found in lower-level languages such as C which is
closer to assembler and can efficiently access the hardware such
as an audio or video device.

I was hoping there might be a perl module like a
fictional one I will call Device::ALSA which would understand the
syntax used in capturing audio from a microphone or line input,
like a microphone input, only not as sensitive, where one
customarily feeds sound from the output of whatever one is
recording from.

There are standard alsa conventions for setting sample
rate and other parameters which I mentioned in the earlier
posting so if one knows what sort of digital stream they nead,
they just stuff those values in to the function whose output is
that stream of digital  data.  What you do with those data is up
to you but the module takes care of getting the bits from the
hardware or sending the bits to your speakers or headphones and
would also support the alsa plugins which are used by the arecord
and aplay utilities for added capabilities.

I can understand why there is no perl module like
Device::alsa because it would not be portable between Windows and
Linus.  The l in alsa is for Linux so basically, I was just
curious to see if anything like Device::ALSA existed and it
apparently does not exist.

Anyway, the FFI concept will probably someday come in
handy for a different project so I will continue with the C I was
working on.

Thanks again.

I would think that one nowadays would use (go through) pipewire for
anything that involves recording and playing sounds.

I've no clue how that would work, though.

Are there any ALSA Perl Modules?

[Martin McCormick]

Several years ago, I wrote some C code which turns one's
computer's sound interface in to a sound-activated recorder that
I could then connect to radio receivers or microphones and record
when audio started and stop recording when there is nothing but
silence.  One essentially sets a sound card to record
continuously but the sound samples go through code that knows
what silence looks like.  In short, silence looks like samples
whose numeric value is exactly half-way between the lowest and
highest voltage that the analog-to-digital converter reads,
commonly either 32,767 representing silence, give or take a count
or two due to digital sampling errors or decimal 128, hex 80 for
8-bit mono audio.

The Advanced Linux Sound Architecture Project has C library
functions for setting sample rates, mono, stereo, big or little
endianness and 8 or 16-bit audio, whatever one needs for their
application.  One can even define samples as signed or unsigned
integers.

Once one gets a stream of ints which are usually 32-bits
wide for stereo or 16-bit shorts for mono, the sound processing
can begin which C is really good at but perl is just as good at
so if one could get the same alsa modules which are used by aplay
and arecord for setting up one's audio interfaces or sound cards,
the manipulation of those data that was done in C could also be
done in perl without hardly any modification to it at all.

Perl has just the right mix of low-level logic and
bitwise operators plus a much more easy-to-use string handling
capability which is why I am asking this question.

I may be looking in the wrong places but, so far, I seem
to be batting zeros when looking for perl and alsa together.

Any good ideas are greatly appreciated, here.

Re: Modules

[Levi Elias Nystad-Johansen via beginners]

I use modules for complex things that I might get wrong. To re-use other 
people's code is often better than to re-invent their solutions.

https://metacpan.org/pod/WWW::Mechanize::Examples has some good examples of 
useful scripts that are short and simple.
Imagine how hard it would be to write the same scripts without the module.

When I have an issue that I think others must also have faced, I look for a 
module to solve the issue.

But I am critical to modules that are outdated/abandoned, heavy with many 
dependencies, or unproven with few downloads etc.

I also remove modules when I no longer need them. I find this easier with 
App::cpanminus

Well, no.  That one didn't work.  I had to be specific about where 
CGI::Carp was installed to get it to work:

use lib '/home/user/.cpanm/work/1512448551.26554/CGI-4.38/lib';

I've read about those, but I'd rather not jerry rig this install just 
to get it to work.  I've been using perlbrew on my Mac (with 5 different perls) 
for years without incident, so that's why I'm at a loss as to what's happening 
on this VPS.  Maybe I should just cut my losses, delete everything, and start 
over.  I just hate doing that after spending so much time on something.  It's 
like admitting defeat and giving up. ;)

I just thought to compare the install on my Mac with the one on the VPS 
and the binaries of perlbrew are exactly the same, but the binaries for 
patchperl and cpanm are wildly different from each other.  Are these customized 
during installation for the platform that running?  If not, would it be safe to 
copy my known good copies over to the server (Mac vs Linux)?

Those errors aren't appearing in the errors log in cPanel.  I couldn't 
find another error log in WHM.

I ran your script and, when I manually include the .cpanm directory, it 
returns:

/home/user/cgi-bin/test.pl syntax OK

otherwise, it returns:

Can't locate CGI/Carp.pm in @INC (you may need to install the CGI::Carp module)

Looks like this has been reported for a few years without a solution:

Could this be part of the problem?  I'm running perlbrew 0.80.

Can you not look a the web server's error_log?  A 500 error would put the
perl error msg in there.  Have you tried just "use" a different module?
Hmm, can you try

#!/home/user/perl5/perlbrew/perls/latest/bin/perl

use warnings;
use diagnostics;

print "Content-type: text/html\n\n";
print `/home/user/perl5/perlbrew/perls/latest/bin/perl -c

That's what I thought.  Shouldn't "cpanm install Module::Name" do that 
on it's own?  There's only one perl install and one alias, and the alias is 
selected.  Running "perl -v" returns version 5.26.1 so how can I get perlbrew 
set to install in the current installation?

you should make sure that the modules you wish to use are in one of the
dirs in @INC. cpanm should install to  the global directories.

I get:

I found a .cpanm directory in /home/user where all the modules are 
being installed.  Could that have anything to do with it?  I tried adding that 
directory with "use lib" but I still get the 500 error.

Thanks,

perlbrew and modules

[SSC_perl]

I've run into another strange problem that I don't understand.  Running 
the script below produces the output "Perl v5.26.1".  However, if I add the 
line: use CGI::Carp qw(fatalsToBrowser);  it produces a 500 error.

On the shared server, this worked as it should, with 'fatalsToBrowser' 
showing any errors.  But the VPS is just backwards - adding it crashes the 
script!  This actually happens with any module and, yes, they are installed:

> cpanm install CGI::Carp
install is up to date. (0.01)
CGI::Carp is up to date. (4.38)

I have been fighting with this VPS setup for almost 2 weeks now just to 
get a functioning modern Perl environment and I'm about at my wits end.  It 
shouldn't be this hard.

I'd appreciate any help.

Thanks,
Frank

I found I had a mess configuration with PERL5_MB_OPT and PERL5_MM_OPT

Removing/unsetting the variables fixed the problem.

Take note at least on rehl, you have to run 'yum install perl perl-core'

Re: Best way to install perl modules

[Benjamin Fernandis]

Hi,

Today I face same previous problem to install package with cpanm.

This time i have already installed Development Tools as suggested by Sam.


For testing it more, i was trying to install dancer by cpanm. First trial,
i got failed and then looked into build log and found some dependent
modules are not there so then i tried to first install them and those also
have some more dependencies and then i have to resolve first from those and
then step by step do install manually and lastly dancer installation works
for me.

Below is my manually package installation.

Please suggest me to resolve this installation problem. Also suggest me if
I am missing anything at OS level.

OS : cenots 7

Ben

 Hi Mike,

 Thanks for your kind response. I tried cpanm instead of cpan, but many
 times, it does not install require dependencies for module.

 For example, when i was trying to install
 cpanm XML::SAX  - it failed and said no Fatal.pm module , then i
 manually first installed that module and then i tried to install
 XML::SAX and it works.

 It happens many times while installing different modules. I mean cpanm
 does not automatically fetch require dependencies for module. like yum

 Is there any tool or something like yum for perl module installations.

Lacking Env.pm basically means your vendor's Perl is broken.  Env.pm is
shipped with Perl itself, and subsequently things may forget to depend on
it ( at least, in a way that cpan tools recognise ) and be silently broken
as a consequence.

It *might*  be worth filing a bug with the respective packages saying hey,
you need Env.pm, but dont depend on it

But the thing that will make life easiest for you is working out why you
don't have things installed that are EXPECTED to be installed as part of a
standard perl installation.

But the general problem is, sometimes people in Perl have external
dependencies and forget to declare them as such.

When they do that, things break.

When things break like that, if you're sure the problem is them failing to
declare the dependency, then you file a bug requesting they declare the
dependency.

Once the dependency is declared, CPAN, CPANPLUS and cpanm will detect and
respond to it.

You want use lib - in particular, to say look in a directory named

use lib './lib';

(in fact, use lib 'lib' would be enough, but I think it's mildly
clearer with the ./ notation)

web scraper modules

[Mike McClain]

Hi,
A few years ago I wrote a script to search a couple of dozen sites
like CalJobs, craigslist, Dice, Indeed, several temp agencies in the
area and a few of the major companies who use electronics techs
for jobs I might care to apply for.
At the time I used LWP::Simple, LWP::UserAgent, HTML::TreeBuilder,
WWW::Mechanize  HTTP::Cookies but many of the sites have modified
their pages so that my program needs to be rewritten.
I'm wondering if anyone has suggestions of modules that make this
sort of task easier.
Thanks,

Which part of the process do you find hard and want to make easier?

The process has 2 important parts:
- downloading the pages
- scraping them

To download, Mechanize is good because it is higher level and offers some 
helpful methods, but it won't help you if those pages are hard to get... if 
they use a kind of anti-scraping protection. In that case LWP is better, but 
Mechanize can use LWP's methods.

For scraping the content, HTML::TreeBuilder is very good.
If you have a good XPath knowledge you may find helpful 
HTML::TreeBuilder::XPath.

CSS is just a subset of XPath, so it is not as advanced, but it has a nicer 
syntax, so if you have a good CSS knowledge, you may use other scrapers like:
WWW::Mechanize::Query
Web::Scraper
Scrappy::Scraper::Parser
Mojo::UserAgent

All of them do the same thing, so it depends which type of syntax do you like

 Each module is used differently. Almost all modules can be included in your
 program with the statement (usually near the beginning of your program):
 
   use Module;
 
 where you substitute the name of the module you are going to use for
 Module. This statement imports the module's program statements into your
 program. This happens at compile time, no matter where in your program you
 actually put the 'use' statement.
 
 You can also import modules using 'do' or 'require', but you need to know
 what those do and why to use them before you use them instead of 'use'.
 
 Modules come in two flavors: procedural and object-oriented. Some modules
 support both flavors. Most modules come with built-in documentation that
 describes how to use them, usually including some sample code statements. To
 access the documentation, you can do the following on a command-line:
 
   perldoc Module
 
 Strawberry Perl may afford another way of accessing documentation.
 
 Procedural modules will import functions into your namespace, so you can just
 call these functions as if they were part of built-in Perl or part of your
 own program.

Well, it is a good idea to explicitly import these subroutines to avoid
having to hunt where these subroutines are coming from:

So you do:

use Module qw( func1 func2 func3 );

Instead of:

use Module;

 
 Object-oriented modules allow you to create objects of the module class,
 and call methods of those objects. To create an object instance of the Module
 class:
 
   my $object = Module-new();
 
 The new() method is a convention. It could be called anything, but most OO
 modules use a new() method for object creation, Some new() methods take
 arguments.
 
 To call a method on the object:
 
   $object-method();
 
 See the documentation for each module to find out what functions and methods
 are available.
 
 There are Perl tutorials for using modules and doing object-oriented
 programming:
 
   perldoc perlmod
   perldoc perlmodlib
   perldoc perlmodstyle
   perldoc perlmodinstall
   perldoc perlboot
   perldoc perltoot
   perldoc perltooc

perlboot, perltoot and perltooc have been deprecated and deleted from the Perl
documentation. See:

http://perldoc.perl.org/perlboot.html

You should use http://perldoc.perl.org/perlootut.html and
http://perldoc.perl.org/perlobj.html instead. For more resources see:

http://perl-begin.org/topics/object-oriented/ (a link to my site)

 Hi Ray,
 
 So, I assume you downloaded whatever modules you chose to because you wanted 
 the whatever functionality they provide.  Since I don't know _what_ modules 
 you chose I'll give an imaginary example and then a specific example from a 
 favorite module I use.
 
   Having said that:
 The CPAN page for a module always includes a SYNOPSIS - this gives a very
 terse example of using the module.  Check there.
 
 For our example I'll use the fictional raspberry.pm.
 It's synopsis reads;
use raspberry;
my $answer = raspberry();

Just a note - you should not call your modules or packages with an initial
lowercase letter, as this is reserved for pragmas:

http://perl-begin.org/tutorials/bad-elements/#lowercase_modules_and_pkgs (link
to a page I created).

 
 The description says:
 raspberry returns a line from the raspberry wisdom list.
 
 In your code then it might be used:
 
 #!/usr/bin/perl
 use warnings;
 use strict;
 use raspberry;   # the use line incorporates the module code into your
 program
 
 my $answer = raspberry(); # the function call uses code from the module
 that you didn't write
 
 print $answer, $/;
 
 and the output might be something like 
 
 Raspberries are delicious!  Eat some soon to feel good!
 
 Now for a specific, real world example:
 
 #!/usr/bin/perl
 use Data::Dumper; 

You forgot strict and warnings.

 
 [ imagine a bunch of code that does something, but you don't quite know
 what] [ someone else wrote it, and it's now time for you to fix a
 problem ] [ there's a huge complex data structure that
 hash of arrays or a hash of hashes or ...? ]
 
 print Dumper( \%my_hash_with_who_knows_what ):

Need clarification in using return value for modules

[*Shaji Kalidasan*]

Greetings,

I am using the following module

[module]
package My::GoldenRock::Utilities;

use strict;
use warnings;

use base 'Exporter';
our @EXPORT_OK = qw(foo bar);
our %EXPORT_TAGS = (all = \@EXPORT_OK);

our $VERSION = 0.1;

sub foo() { print Inside foo\n; }

sub bar { print Inside bar\n; }
[/module]
#Please note that I am not using a return value (1 in this case) as the last 
statement

[code]
use My::GoldenRock::Utilities 'bar';

print bar();
[/code]
 
[output]
Inside bar
1
[/output]

From where is the number 1 coming in the output. Earlier I mentioned '1' as the 
last statement in the module and I thought '1' is printed in the output owing 
to that. How to eliminate '1' from the output?

Please explain the intricacies of

use base 'Exporter';
our @EXPORT_OK = qw(foo bar);
our %EXPORT_TAGS = (all = \@EXPORT_OK);

Any pointers are greatly appreciated.

Shaji

Your subroutine bar() has a print statement in it, that prints Inside 
bar and a newline.  bar() then returns the value of the last statement 
(which is the print in this case).  The print function returns true 
when it succeeds, so it returns a 1 in this case.  Your mainline code 
then prints (with another print) the return value of 
My::GoldenRock::Utilities::bar().  This is where you printed '1' comes from.

Hi Chenlin,

You can use corelist to find out if it is part of standard distribution or not.


corelist XML::DOM

XML::DOM was not in CORE (or so I think)

corelist IO::File

IO::File was first released with perl 5.00307

corelist strict

strict was first released with perl 5

Package modules and EXPORTER use

[Mark Haney]

I've got an odd situation here and I'm not sure what to think about it. 
 I've had to pull several subroutines into it's own package since they 
all have similar functions (as far as that goes) and I find that I reuse 
them more than I thought.


My question stems from the EXPORTER directive.  I've got one package 
that does NOT include an EXPORTER nor exports any subroutines, yet it's 
used by virtually all other parts of the system.  I've never really 
noticed it before, which is why now it's so curious.


I can't find anywhere that EXPORTER is optional, but also can't find 
anything special about the content or syntax, etc about the package that 
doesn't use it.


So, should I use it?  Does it really matter in small apps?  What am I 
missing here?

Did you put them into their own package or also into their own module? I hope
you know there's a difference. Do the module and package share the same name.

 
 My question stems from the EXPORTER directive.  I've got one package 
 that does NOT include an EXPORTER nor exports any subroutines, yet it's

By EXPORTER you probably mean «use parent 'Exporter';» (or use base
'Exporter') along with the special variable of @EXPORT, @EXPORT_OK, etc. In any
case, is it a module that does not have a package specifier (in which case
it will dump its contents into the current package). Maybe it does have a
package specifier, but names from it are called using MyPackage::my_sub()
(i.e: fully-qualified names).

 
 I can't find anywhere that EXPORTER is optional, but also can't find 
 anything special about the content or syntax, etc about the package that 
 doesn't use it.

Use of Exporter.pm (or Sub::Exporter for that matter) is optional, and you may
opt to avoid them if you're creating an object-oriented interface.

 
 So, should I use it?  Does it really matter in small apps?  What am I 
 missing here?

Can you give a code sample that reproduces the issue?

Let me see if I can explain better. I have a Package called EMBMON::DAO 
which (as may be obvious) handles the object for accessing the database. 
This one does NOT have an EXPORT line yet nearly all the code in the web 
app uses the subroutines (about 2 dozen) in this package.


I also have a package EMBMON::UTIL that houses various subroutines for 
things like calculating averages or other things specific to the app. 
There are only 6 subs in that package and it HAS an EXPORT line 
exporting the subs in the package.


Vaguely, I knew there was a difference in modules and packages, but 
nothing I've ever had to write has really required modules and only one 
or two packages.


Does this help?

So - there are subroutines that are being called in the package as 
subroutine calls e.g.


my $answer = dosomething($some,@parameter);

(As opposed to some methods being called in the class like

my $dao_thing = EMBMON::DAO-new(%configuration);
$dao_thing-do_something($some,@parameter);

To do the first, your package would have to perform the same magic 
that Exporter would do - which would work the same.  I'd recommend using 
Exporter because it provides a rich feature set that is known to work 
and is well documented.





I also have a package EMBMON::UTIL that houses various subroutines for
things like calculating averages or other things specific to the app.
There are only 6 subs in that package and it HAS an EXPORT line
exporting the subs in the package.



Which is probably the better thing to do.

As I age, I find myself importing names into my package namespace less 
and less often - I actually prefer to use the fully qualified subroutine 
names, because it makes it (in my opinion) easier to find the 
documentation for a specific function call.


Of course, being a big old OO bigot - I prefer objects and their method 
calls to functions any day of the week and twice on Sundays.

 Hi Mark,
 
 
 So, should I use it?  Does it really matter in small apps?  What am I
 missing here?
 
 Can you give a code sample that reproduces the issue?
 
 
 
 Let me see if I can explain better. I have a Package called EMBMON::DAO which 
 (as may be obvious) handles the object for accessing the database. This one 
 does NOT have an EXPORT line yet nearly all the code in the web app uses the 
 subroutines (about 2 dozen) in this package.

Can you give us an example of how your main program calls the subroutines in 
the EMBMON::DAO package? Are you calling them as simple functions (which need 
to be exported_) or as object methods (which do not)?
 
 I also have a package EMBMON::UTIL that houses various subroutines for things 
 like calculating averages or other things specific to the app. There are only 
 6 subs in that package and it HAS an EXPORT line exporting the subs in the 
 package.
 
 Vaguely, I knew there was a difference in modules and packages, but nothing 
 I've ever had to write has really required modules and only one or two 
 packages.
 
 Does this help?

Including code samples always helps!

moving from ubuntu 10.04 to 12.04. how to have same PERL modules there?

[Rajeev Prasad]

Hello,
 
I am going to move (not upgrade) from my current ubuntu ver 10.10  to ver. 
12.04 (fresh install). I will restore my data and scripts there and have them 
ready.
 
But, how do i have all the required modules (which i have installed on my 
current PC over months) installed on target system?
 
I do not want to have old versions of software on new PC, buut i just want to 
make sure that all which was installed (in regard to PERL) on old PC should be 
on new PC as well.
 
for e.g.
on 10.10: perl ver is: v5.10
on 12.04 it is: perl (5.14.2-6ubuntu2)
 
is there a quick method to do that?
 
thank you.
Rajeev

No, but you can adapt this algorithm: 
http://onionstand.blogspot.ca/2012/05/moving-modules-across-perlbrew.html


Use this command to create the list of installed modules:

$ perl -MExtUtils::Installed -E 'print $_\n for 
ExtUtils::Installed-new-modules'  /tmp/installed.list


Copy installed.list to the target system, install `cpanm` and then use 
this commnad to install them:


$ cat /tmp/installed.list | cpanm --interactive

Re: moving from ubuntu 10.04 to 12.04. how to have same PERL modules there?

[Rajeev Prasad]

thx Shawn,
 
I guess, it would not check which modules have newer versions available, and 
will install the same modules whihc were there in old PC.
 
I install only those modules which come thru ubuntu, so that (I assume) there 
is some compatibility testing already done. (anD) it does not break anythign 
else in my PERL install.
 
I will try it on test system first.
 
I found another simple way, which works for me (my scripts are simple ones): I 
would just go thru all my scripts and see what am I 'useing' like __  use 
abc::def  __ and then make a list of those. then go on target system and open 
some tool like synaptic (for ubuntu) and install all those modules. :) I will 
try that too.
 
ty.

From the following line:

   LWP failed with code[500] message[Can't connect to
cpan.strawberryperl.com:80 http://cpan.strawberryperl.com/ (connect:

it looks like LWP is unable to connect to the site to download the modules.
 You need to make sure your connected to the internet.  Also, if you are,
check your firewall and ensure your not blocking access to the application.

RE: How to compile just the current perl module, ignoring all the other included modules

[Nemana, Satya]

Hi Shawn

How do I use this option of -MO=Deparse when executing a perl script with an 
embedded #! Prompt?
Our scripts start with the line
#!/ats/bin/perl -w

I tried adding the parameters here, but got the following errors

Too late for -MO=Deparse option at ./startAutomation line 1.
BEGIN { $^W = 1; }

Then there are a host of other environment variables set before executing the 
functions in the modules by a call to 
unless ( my $return_val = do $test_suite_list_file ) {
die ERROR: Couldn't parse test suite file \$test_suite_list_file\: $@\n 
if $@;
die ERROR: Couldn't 'do' test suite file \$test_suite_list_file\: $!\n 
unless defined $return_val;
die ERROR: Couldn't run test suite file \$test_suite_list_file\: $!\n 
unless $return_val;

is there other way of using the option -MO=Deparse??

Thanks,
Satya

That's very unusual, most scripts take only a few seconds to compile. Try:

perl -MO=Deparse MyModule.pm

No, the module has to be mentioned on the comnmand line, but you can say

  /ats/bin/perl -w -MO=Deparse prog.pl

which will have the desired effect. You can also add the additional 
files in the same command if necessary using the -f option like this


  /ats/bin/perl -w -MO=Deparse -f file1.pl -f file2.pl prog.pl

Also you should be using

  use warnings;

instead of -w in the #! line.

RE: How to compile just the current perl module, ignoring all the other included modules

[Nemana, Satya]

Hi Rob

All I got from this exercise is 

./startAutomation syntax OK 

and a complete print of the startAutomation perl file with the fully qualified 
function names, all the variables used in the program at the beginning of the 
program.

From the time command output, as used in the command time /ats/bin/perl -w 
-MO=Deparse ./startAutomation 
I have
92.765u 110.414s 3:24.11 99.5%  0+0k 0+0io 0pf+0w

How do I know module wise, how much time perl is taking for compiling each of 
the modules and where perl is spending time in the compilation?

How do I enable more verbose in the compilation or execution of the program?

Thanks,
Satya

4-5 minutes?!  Either you have an unbearably slow computer or something

How to compile just the current perl module, ignoring all the other included modules

[Nemana, Satya]

Hi Gurus

I have to compile a perl module which includes a lot of other modules.
The other modules will not change during compilations of my current module.
Only my current module keeps on changing.
The compiler however starts compiling from all the modules included in the 
current module with the use directive and the dependent modules.
Is there any way to work around this intelligence of the perl compiler to 
ignore the compilation on the other modules and just compile the current 
program/module?
I want these errors if any to be only caught in the run time. (although it will 
not happen because ultimately I will compile the complete modules to run the 
program)

Thanks,

Perl has to compile and run the modules yours depends on to have the 
correct context. Without them, it cannot determine if your module is 
correct.

The simplest way to do this is to use the exec command it is not the right
way by any means but it should work most of the time. The main problems you
will find is that you cannot do much error handling, you would basically
only be able to see if your script executed SSH correctly or not and that
is all that you would be able to do... As far as output you should be able
to capture that but it would be just plain old flat text any other work you
might want to do with it you would have to do using regular expressions
etc...

All in all it is not a nice solution, but if you really cannot use modules
then you are likely stuck with it. I would advise you to have a look at the
Net::OpenSSH module. I know you said no modules but hear me
out... Net::OpenSSH is a pure perl module that doesn't have any mandatory
dependencies (obviously, besides requiring OpenSSH binaries). This means
that you could include it as a part of your program as a module that does
not need installing as there is no need to do this. Of course you will have
to go into the gutts of the module and find out how it calls the OpenSSH
binaries and make sure that you deal with a situation where the binaries
are in another location then the one on your machine and of course the case
where the are not installed at all. It is going to be a nasty thing and you
will have to deal with solving the same problem over and over again with
every new release of the Net::OpenSSH module you want to use... You also
will need to deal with stuff like outdated versions of OpenSSH and other
such wonderful situations.
Personally I would not go this route but it really depends on what you need
to do if all you need is just a directory listing the exec command might be
enough, if you are looking for more things and need to do proper error
handling then you will most likely need to find a way to deal with a module
anyway.

By the way, if you are using SSH to connect to remote machines why could
you not simply run this on a single machine? This would make your life a
lot simpler as getting a module installed on a single machine is a lot less
arguing with the administrator of the server park then getting it installed
on a lot of machines. After all if you are to use perl but have to live
without modules then what is the point... Perl without modules is like
C/C++ without external libraries it will work but it is going to be a
massive pain in the rear and likely a very difficult slow and error prone
job.

Rob

Subject: Re: can only install cpan modules as sudo

in response to the question of writing a perl to python converter i
forwarded to the list thisand no one has responded nor has it appeared on
the list.. is something wrong with the list?
Maybe a better project would be to work toward the development of a standard
xsl style sheet able to parse source code or binary of each software
language into a tree such that xslt could parse the intermediate tree and
transform its structure into a multitude of other language source codes or
binaries. I do not know if it would be easier to work at the binary level
than the source code level. But I believe much of the technology to
transform source code and binaries from one language set to another language
set already exist. 

xsl, xslt tools I believe have a perfect fit in perl.

 XSL [code lang1], [ XSLT :: XSLT ], XSL [code lang2[

 Parse the code, build the tree::parse the tree, output the new code.



Merely writing xsl parsing and tree layouts for each language [source or
complied binary] and conforming the xsl style sheet to the xslt transform
standards, the machine genetics and super protected kernels that talk to
them, might resolve to trivial. Moreover there are lots of persons with
transforming experience around who might help.



Is it not possible to develop the transforms between languages in xslt style
sheet fashion? Would such a transform impose on the copyright or patent
rights of one or more languages or language parts?

Depends whereabouts it is on your machine. If ActiveState resides in ~/ then
yes, I would. If not, it's entirely optional  you can just go ahead 
install perlbrew as per the defaults.

in response to the question of writing a perl to python converter i

Maybe a better project would be to work toward the development of a standard
xsl style sheet able to parse source code or binary of each software
language into a tree such that xslt could parse the intermediate tree and
transform its structure into a multitude of other language source codes or
binaries. I do not know if it would be easier to work at the binary level
than the source code level. But I believe much of the technology to
transform source code and binaries from one language set to another language
set already exist. 

xsl, xslt tools I believe have a perfect fit in perl.

 XSL [code lang1], [ XSLT :: XSLT ], XSL [code lang2[

 Parse the code, build the tree::parse the tree, output the new code.



Merely writing xsl parsing and tree layouts for each language [source or
complied binary] and conforming the xsl style sheet to the xslt transform
standards, the machine genetics and super protected kernels that talk to
them, might resolve to trivial. Moreover there are lots of persons with
transforming experience around who might help.



Is it not possible to develop the transforms between languages in xslt style
sheet fashion? Would such a transform impose on the copyright or patent
rights of one or more languages or language parts?

can only install cpan modules as sudo

[Ryan.Barracuda]

Hi all,

I can only install cpan modules as sudo. I installed ActiveState Perl
v.5.14.2 and cpanm without a problem.

$ cpanm Net::SMTP
-bash: /usr/local/bin/cpanm: /usr/bin/perl: bad interpreter: No such file or
directory

However, with sudo

$ sudo cpanm Net::SMTP
Net::SMTP is up to date. (2.31)

How do I install cpan modules without being sudo?

Ryan

Re: can only install cpan modules as sudo

[Ryan.Barracuda]

Another example:

ryan-munsons-macbook-pro:bin barracuda$ cpanm MIME::Entity
-bash: /usr/local/bin/cpanm: /usr/bin/perl: bad interpreter: No such file or
directory

This was not installed. When using sudo, however:

ryan-munsons-macbook-pro:bin barracuda$ cpanm MIME::Entity
-bash: /usr/local/bin/cpanm: /usr/bin/perl: bad interpreter: No such file or
directory
ryan-munsons-macbook-pro:bin barracuda$ sudo cpanm MIME::Entity

Console Modules for Windows (DOS mode)

[Steven Perry]

Does anybody know of any modules to create console applications for windows?
I don't want a GUI like tk does. I want it to be text based and run in a DOS
window.

I saw the below example but couldn't get the curses module to work in
Windows. 
This is a good example of what I'd like to do.

Google wasn't any help but it was probably the terms I used.

Thanks.

I recall being told by someone that he had a problem getting PDcurses up and
running on Windows. You can try http://metacpan.org/release/Win32-Console as
long as you don't mind your code being Win32/Win64-only. If you do, then
create a layer of abstraction for it and Curses.

Re: Strawberry Perl Installing CPAN modules

[Perl developer]

Shlomi,
  I installed Terdata software packages like cli, teragss, and tdicu. I
edited windows hosts file.
Now I got the following error.

dmake.exe:  makefile:  line 871:  Error: -- Missing targets or attributes in

The following perl script is used to connect to SQL server database using
DBI and DBD::ODBC modules.

*my *$dbh = DBI-*connect*(DBI:ODBC:Driver={SQL
Server};Server=$db_instance;Database=$db_name;UID=$db_user;PWD=$db_pass) or
*die*(\n\nCONNECT ERROR:\n\n$DBI::errstr);


Using ODBC I am getting the following error.


DBI

Any help is appreciated. Thank you.
