And we were trying to explain to you that it doesn't really matter 
whether you have some builtin method of the builtin types or just a 
buch of builtin functions&operators. And that we actually prefer the 
second for the very basic types like numbers and strings.

I asked you in another mail whether you'd rather write
x = y.sin().plus(z)
or
x = sin(x) + z

What's the reply?

Do not sweat about "real whatever" langauges. That's not what gets 
the job done. So Perl doesn't treat the base types like objects. So 
what? That doesn't make its support for OO programming any less 
complete.

Yeah in strongly typed languages with oldstyle type system (read all 
mainstream strongly typed langauges including Java and C#) need some 
base "Object" type that all other types, including the base ones, 
inherit from. You don't need this in Perl, you can pass a number or a 
string or an object to the same function or method and the method may 
easily be programmed to accept them all and do the right thing. Even 
if some of them are not considered objects.

In my opinion forcing everything to be an object is wrong. Or at 
least inconvenient. (Especialy the way Java/C# does it.)
But that's just my personal preference.

Dear friend!
I MEANT STANDART TYPES. ARE YOU ABLE TO SEE THE DIFFERENCE? If you 
assign the value for string variable it automaticaly gets the number of 
methods belonging to String object. And as an example I wrote the 
s.replace statement.. The similar approach has Ruby. Of course, if you 
need more complicated functionality you make "import" or another 
including of some module.

I wrote about this only to show what can the real OO language (Python of

s.replace(...) is a consequence of "everything is object" thinking.

Look at the following:

import re;
m = re.match(r"(?P\d+)\.(\d*)", '3.14');
//After performing this match
//m.group(1) is '3', as is m.group('int')
//and m.group(2) is '14'. 

There is a similar ugly thing in Java.
All of this because you want everything to be an object.

Can you tell us how will you perform the above
matching without import re; :).

In Perl you don't absolutely need a kind of use RE; to be able
performing regular expression macthing.

So, don't force my $s = "I am Perl Guru"; to be an object and contain a
replace() method.

$s is a string will be treated as is in Perl.

José.

So you have to do basically the equivalent of use CGI to be able to use 
the cgi object and therefore have access to all its functions.

And if you say, "Well I don't have to do my $cgi = new CGI so its 
better" is like me saying that perl is better because my shebang line 
takes up less file space that your python path. It's just pointless.

No I don't understand.
Who cares if you do a regex or a built in function/method that does the 
regex for you?

You're arguments are all like "My dad can beat up your dad" when the 
truth is, in different circumstances either dad could beat up either dad.

Its better to you because you understand it, which doesn't make it 
better or worse.

In my opinion and experience Perl does everything I've ever needed to do 
programming wise, its easy to learn and expand, and has been easier to 
do that with than any other language I've played with. Your experience 
may be different. So in that sense my dad can beat up your dad, but in 
your experience it would seem your dad can beat up my dad :)

So to the OP: chin up! Python (or any other language) isn't going to 
replace Perl (and Perl is not going to replace any other languages), 
especially with lame arguments for Python like we've seen here ;p

(code snipped to save space)


i found the Python script to be very readable- i am far more comfortable
with Perl syntax, but it worked for me.

I think there are two arguments which can be made here- both good.

1.  code syntax (limitation/flexibility/readability) - how languages
differ and language preference.

2.  Language strengths and weaknesses (outside of syntax).


My impression was that OO in Perl has historically been fraught with 
CPU overhead - this will change in Perl 6?  (argument number 2)

I like the functional() as apposed to the menthod.syntax() because i can
more easily visualise the path that data takes through the code.  makes
my life easier (argument number 1)


for me something like $new_s = change($s, $string); just works better
for me.  anyway, the advantages of encapsulation are easily produced in
functional() code with good coding practices.

of course, now we're talking about meta topics as apposed to particular
Perl
questions- but I think the argument is worth while.

I won't even reply to the person that said, perl is old news.  And that everyone talks

Then comes perl.

No, you're using Python's built in string operators. Perl has them too:

 $s = "I am a Perl guru";
 ( $new_s = $s ) =~ s/perl/python/;

Remark, no additional modules.

You're using methods defined by modules that live with Python.

You haven't come across eval{...} yet, have ya?  

The differences among Perl, Python, and Ruby are mostly semantic -- each 
of them can accomplish all the same tasks, but they wrap up the way to 
implement these tasks in ever-so-slightly different syntax. But so what? 
Any of them are *much* more pleasant to work with than Java, C/C++, or

Sorry? Oh you want substr() to be a method, not a function, you want 
to write
$line.chomp();
instead of
chomp($line);
right?

I'd rather not.
Not everything has to be an object. Not everything has to be called 
like methods.

Would you like to have to write
$x = $y.sin().plus($y)
instead of
$x = sin($x) + $y;
?

There is a big difference between a functionaly complete OO language 
and a language that forces everything to be an object.

To Randal and Chris. You all don't understand me. CGI is a module, 
earlier wrote and stored in a separate files. I don't mean such objects.

Python and Ruby don't write the code for me. But look at this Python code:
s = "I am Perl guru";
new_s = s.replace("Perl", "Python");
Huh? Remark, no addition modules.
The similar way is in Ruby and other nice.
By the way, these languages have people friendly exceptions handling ;) with 
try-except in Python and begin-rescue in Ruby.

I'm not quite following you, but I'm not sure why you think that
Python or Ruby writes your code for you.  There's as much (or little)
work to create an object in Perl as there is in either of those other
languages, in terms of what matters every day.

Huh?

  my $cgi = new CGI;

And hey presto, $cgi has all the methods of the CGI class.

And so on and so forth for all other OO Perl. (And most other languages 
with OO capabilities, for that matter, including C++.)

What are you talking about? The fact that strings, scalars, etc aren't 
usually thought of as objects (even though they have both data and 
standard methods for operating on them)? 

Unlike what I suspect Randal would say, I like Python. I have no problem 
with it. It's a nice language. But that doesn't invalidate the fact that 
Perl does indeed have a complete and fully functional OO framework, even 
though the language didn't grow up around this framework the way Python 
did.

2004-10-01 Thread Nicolay A. Vasiliev
Hello!
This is very interesting thread. So, let me add some words to this. 
(Sorry in advance my English).

Best of all, let me express my respect to Mr. Schwartz. I read your 
Lama-book and I think that's very useful for every Perl newbie. I got 
such chain: Lama-book, Camel-book and Cook-book :).

I love Perl and work with it more often than Python, but...

Perl is more powerful.  Python is simpler.  Python is for people
who don't want to master a language -- just use it casually.
 

This is no serious statement. Python is simple and power too. Read 
please Bruce Eckel why he left Perl and came to Python.
At least, it's really object-oriented as against Perl and it has more 
funny syntax :).

However, if you're gonna spend two or more hours a day hacking code,
Perl is definitely the right place to be.  Still.
Those Python weenies are all just casual programmers complaining
that for Perl, "with great power comes great responsibility".  Let'em.
Perl's support only grows.  I used to be able to follow the CPAN "new
modules list" by examining the daily run at search.cpan.org/recent.
But no more.  Look at all the new modules just in the past *seven*
days.  (It's typically a full web page for each day!) If that doesn't
show you an intense activity in the Perl community, I really don't
know what else I could show you.
 

Python community is large too (of course not yet as perl community 
because it's more young), and it grows too. Let me know please why this 
is a good - such enormous modules number for one task? In this case I'd 
like to think noone from them is clever and bugs free. That's enough one 
or two clever modules like in Python, that even could be included into 
standart distribution.

Ask your Python friends where such a similar list exists. :)
Python may be newer, but Perl is more mature, and here to stay.
Remember "new coke", and how long we had that. (If you're old enough
to remember that fiasco.)

I have that feeling now, one person (the one paying me to learn Python)
said they tried Perl about 10 years ago and couldn't really it and
understand RE. Well, your comment kind of sums him up. I have just bought
"Mastering RE from O'reilly", so I don't get scared of them :-)

The only reason I might find Python interesting is that Fedora uses it for
all the sys-admin utils, so I can help with those. (I am
http://FedoraNEWS.ORG/ghenry so I have an interest in Fedora)

I'm almost at that level, but I should be doing other jobs, but I can't
seem to pull myself out if Vi to do technical documentations etc ;-)

Again, thanks for this. My morale is now completely topped up, so I am
going to shell out for Programming Perl, although I do have the CD
Bookshelf 3.0 (better than 4.0)


Lastly, I just want to say that these kind of responses are what I love
about the open source etc. communities. Everyone is friendly (give or
take) and as long as you ask sensible questions, people will chat. After
all, we are all people.

If fact, this gives me the excuse to say why I am hooked to Linux and OSS.
When I setup my Linux company: http://www.suretecsystems.com I e-mailed
Linus to ask if Tux was registered to him, as the original company name
was going to be Inventux Solutions Ltd. Lo and behold he replied, with a
kind, "Nope, go ahead".

Well, from that day I have been hooked. Would Bill Gates answer a personal
e-mail? Would he f**k...

Thanks,

Gavin.

Perl is more powerful.  Python is simpler.  Python is for people
who don't want to master a language -- just use it casually.

However, if you're gonna spend two or more hours a day hacking code,
Perl is definitely the right place to be.  Still.

Those Python weenies are all just casual programmers complaining
that for Perl, "with great power comes great responsibility".  Let'em.

Perl's support only grows.  I used to be able to follow the CPAN "new
modules list" by examining the daily run at search.cpan.org/recent.
But no more.  Look at all the new modules just in the past *seven*
days.  (It's typically a full web page for each day!) If that doesn't
show you an intense activity in the Perl community, I really don't
know what else I could show you.

Ask your Python friends where such a similar list exists. :)

Python may be newer, but Perl is more mature, and here to stay.

Agreed. Thanks for this. My morale is up, but it's looking like I might be 
getting paid to learn Python, which is a bonus, but my heart is with Perl.

You know, I'm kinda going through a similar thing. I wrote a script to search for 
users in an LDAP directory and update an attribute at the same time. I decided to 
write it in Perl because it looked so easy. And, it was. Works like a champ. Being new 
to Perl, and this was my first script, I was amazed at the power in a short amount of 
code. I've written in C, C++, Java, Lisp, Ada, Modula-2, Prolog, Pascal, and none of 
these are as easy as Perl (although Java is nice).
 
However, my co-worker, who is familiar with JSP, began writing an HTML form to collect 
input data to pass to the script. We found that JSP and Perl didn't mix very well. In 
fact, we are still having trouble getting the two to integrate (probably ignorance 
hold us back).
 
What's the point? The point is that sometimes a language choice defines an

OS (or browser). If Windows were my primary OS and I was writing a commerical 
application, I might think twice about Java. If the application must be cross-OS

Fortran, Cobol, Lisp, C and Basic are older and people still use them.
There are always people who will say that X is better then Y (and people who 
will say that Y is better then X) and maybe for them it is.  It could be that 
they don't fully understand X and Y (and A, B, C and D) and are making a 
judgment on limited knowledge.  It could be that their particular 
circumstances are more conducive to using Y instead of X.

As a professional programmer you should learn many languages and use the best 
one for the circumstances at hand.  :-)  IMHO

THese days Python is gaining support in the field.  But I do think it is
mainly hype.

I do think it is not the question of programming language. Python has
its merits, some good points which are not implemented in Perl. BUT
Do not be confused you do your code, so you can be smarter than Python.

My Good Lord, where have you been? Python is _already_ old news. Ruby, 
baby! :-)

I am on the right path?
The right path is probably to learn them all, and pick whichever 
satisfies you the most. Or use the right tool for the right job.

I know not everybody have the time to learn new programming languages 
every few months. But frankly I think that's the best advice I can give 
you. Learning new programming languages will make you a better 
programmer, and it will asnwer your own question on whether you should 
continue using language X, use both X and Y, or move on to Y completely.

Here's my own experience, hopefully it can help you. I know Perl since 
1997. It has taught me _a lot_ (about programming, about the hacking 
culture, about other languages). Then I started to be interested in 
Python around 2000. Despite 1-2 years trying to familiarize and use 
Python, it never really got to me. I guess I never enjoy programming in 
that language. Nowadays I very rarely use Python at all. I install 
Python mostly just to run BitTorrent.

Then I started to be interested in Ruby in 2001. This I like. But 
despite promising myself to replace Perl with Ruby, today I still 
program like 50% : 50% in Ruby : Perl. There are just some things that I 
can write much faster and more convenient using Perl. Especially when 
writing one liners or when I can just use one or two CPAN modules and 
get the job done.

And then there's PHP. I use (or have to use it) since 1999. Despite 
swearing several times never to use PHP again, and cursing every time I 
have to code many lines in it, today I am still stuck with PHP at times.

I found that, once you learn enough Perl, you just can't let it go 
completely. Perl and CPAN are too damn useful :-)

Re: Becoming Disenheartened - Everyone talks about Python and says Perl is old news.

shouldn't be learning Perl as it's old and Python is better.
Python is different not necessarily better.
Since starting to learn Perl though, every other language I started to
learn/t, C, PHP etc. seem to make more sense now, as Perl has cleared
things up.
Because Perl rocks!
When I look at Perl, I can understand it (it kind of looks like bash),
when I look at a Python script, ugh.
I have been also trying to do some gui work with perl using wxperl, Python
seems to be much better suited/supported (for wx) and I couldn't find very
many docs for wxperl. What else is good looking to use?
have a look at tk at cpan
I love CPAN.
Another plus over many other languages. Perl has many advantages over 
other languages.
1) Its readily available in most systems as its alreayd installed.
2) Its capable of any task any other language is
3) It can be run persistantly or as part of apache as needed but is not 
necessary.
4) If it is part of apache and you expand its functionality by adding a 
module you don't break apache half the time like another bloated 
language who name I won't say (its initials are PHP ;p)
5)

Basically, my morale is getting low and I need a boost from you guys. Perl
isn't old is it?
It is mature, that is one thing that makes it great, less "oh crap 
upgrade to 4.3.8 or you're server is vulnerable" like the other 
unmentionable language I hinted at earlier.

I am on the right path?
Yes you are padawan. One thing that makes other languages appeal to 
people is;t anythgin to do with the language itself. Rather its the 
developers and there wise use of nice design. For example, phpbb is an 
excellent forum. There are tons of other forums that have the same 
functionality but it just looks slick so people just use it.
Of course the point being is that its html and css that make people 
choose it, not PHP.

With perl, we seem to tend toward, "here';s how you do that" and not put 
much into the presentation (IE html/css, etc) and therefore it *looks* 
clunkier on the outside.

So lets all keep using Perl and make it look nice so it sells!!!
Be kind ;-)
use The::Force;
Thanks all,
No woriies :)
