I am not very familiar with perl. Although, I do have shell scripting experience.
I thought this would be easier to do this in perl.
I have a file that doesn't have a field delimiter between the columns and I want to add a colon between each column. I can identify the columns by hard coding the range:
such as "col1 to col 10" "col11 to col24" etc...
I am stuck. Any advise would help. Thanks.

If the column ranges are guaranteed to be the same, you can do
something like:
my @fields =3D unpack("a10 a14", $line);
to extract out the fields in each column. Then you can re-print them
with colons in between them like this:
print join(':', @fields);
Here's a quick one-line solution. If you have a file (named
"input.txt") with these two lines:
1234567890abcdefghijklmn
happy day
Then running this one-liner:
# For Unix:
perl -wlne 'print join(":", unpack("a10 a14", $_))' input.txt
# For Windows/DOS:
perl -wlne "print join(':', unpack('a10 a14', $_))" input.txt
will get you this output:
1234567890:abcdefghijklmn
happy :day
Note that trailing spaces aren't stripped (you can see an example
of this this in the second line of output). If you want them to be
stripped, replace "a10 a14" with "A10 A14". Then your output will
look like:
1234567890:abcdefghijklmn
happy:day
You can look up the documentation for join() with "perldoc -f
join". You can read the documentation for unpack() with "perldoc -f
unpack". You can look up the letter templates (such as "a" and "A"
that you pass into unpack()) with "perldoc -f pack".
I hope this helps!

This might be just a mental glitch, but I seem to be having a problem
wrapping my mind around POD. My mental image is javadoc, which allows
me to produce HTML documentation of Java classes from internal
documation (in Javadoc format) by running a command.
If I document my Perl code (either an executable or a PM) using POD
formatted text, what command do I run to produce a series of HTML
pages?
What I want to do is pass a source listing (such as some_script.plx,
or SOMEPM.pm or <some_perl_dir>) to a utility and have it output HTML
files.
Thanks, CC.

Yeah. I tried that. This isn't the same as the javadoc command.
I can write a (small) perl script that takes a file or a list of files
as input, and produces an html file for each input, plus an index.html
that hyper links all of them. However, I'd have to spend several days
to get it right. It seems to me that this is something that someone
else might have written, but I can't seem to find it.
Maybe I'm unique in that this is the first time that someone has
thought of this. I think not ... which is why I'm confused.

Have you looked on CPAN for POD-processing modules? You will get lots
of hits. (I haven't tried any of them). So, no, you are not the first
person who has tried this.
perldoc is not the same as javadoc. javadoc will scan the Java source
and extract information from Java methods and annotations. perldoc
scans the Perl code and extracts information from between POD tags that
is independent of the code.

For ActivePerl on Windows, when you use their PPM tool to install
modules, it grabs the module, installs it and generates HTML on the fly
to add into index.html. You could take a peak into that code to see how
they do it. I am pretty sure it is all perl.

Yeah, same idea but with the code I write. We lost a programmer who
left eight years of code and ZERO documentation (not Perl code).
Guess what the latest initiative of management is right about now!
I never minded writing javadoc comments, and I don't mind writing perl
comments in POD format. I /do/ mind jumping through hoops to generate
HTML pages.
I use Strawberry (on M$), but looking at ActvePerl is a good idea.
Thanks.

Well, the obvious script "that someone else might have written" is of
course pod2html. Maybe you should start by explaining why that isn't
adequate for your needs (I can think of a couple of reasons, but my
reasons are probably not the same as your reasons).

You can use "pd2html" to accomplish that. For example, let's say
you want to read the perldocs for the Math::BigInt module. You can
read them straight up with the command:
perldoc Math::BigInt
but if you'd rather read them with a web browser, you can use
"pod2html" like this:
pod2html Math::BigInt > math_bigint_documentation.html
then open the file "math_bigint_documentation.html" in your favorite
web browser, and enjoy!
There are more formats you can read the perldocs in. For example,
if you prefer to read a LaTeX-formatted documentation, you can create
one with the command:
pod2latex Math::BigInt > latex_file
Incidentally, I can't always remember the proper formatting codes
to use, and instead of looking them up with "perldoc perlpod",
sometimes I prefer to pick apart an already written POD and learn by
example. (If you haven't figured it out by now, I often use the
Math::BigInt module to see how some POD formatting was done.)
If I want to see how some formatting was done in the Math::BigInt
module, I type:
perldoc -l Math::BigInt
(that's the letter "ell", not the number 1)
That shows me where the module's file is literally located, then I can
read it with any text viewer/editor I have available.
I can also skip a step just by typing:
perldoc -m Math::BigInt
and then I'll be immediately shown the module file's exact contents
(code, POD, and all).
I hope this helps!

The simple answer is that it doesn't do what I want it to.
For example, suppose I have the directory listing shown below because
it's rather lengthy.
Further suppose I run the following command at the command prompt,
> generate_html_from_embedded_pod_in_perl_source_files *.pm *.plx *.cgi
expecting it to generate a sub-directory (perhaps called
'documentation') with the following files:
- index.html
- CCC_LOCATIONS.html
- console.html
- SQL.html
- etc.
I want a separate html file for every perl source file. I want the
index.html to list and link to each html file and each html file to
extract all the POD embedded in each plx, pm, or cgi file. pod2html
doesn't do this.
If nothing does this, it's okay. With a little effort I can write a
clunky something that does a minimal job. Obviously, I'd rather use
something the has been written and tested by someone who knows what
they are doing better than I do.

Don't test $@, but test the what the eval returns.
eval {

This is a hack intended to work around destructors clearing or
changing $@ which happen to be executed automatically before the 'eval
scope' is left using a version of Perl older than 5.14, based on the
'ideological standpoint' that fixing broken code is Just Completely
Wrong[tm] and that one should always prefer adding bizarre
workarounds, ideally, even in places where the aren't needed, instead.
Anything else just makes the code too easy to understand and since "it
was hard to write, it should be hard to read" ...

I installed 5.10 from Paul's site into root of a drive that also had
Paul's environment on it. Once again nothing works CPAN wise. Usually
"make test" runs no tests - they all come back "no subtests run". If
you try the tests individually they sometimes run OK, sometimes fail
and sometimes hang needing a CTRL-C.
On top of this I have the same problem as 5.8.2 in that the supplied
modules are too old to update. Choose a module, does not really matter
which, say A.
A won't install because it requires B.
B won't install because C is too low a level.
C won't install because A .......................
These are modules like Test* Module::Build etc. All you need to get up
tp date - except you can't. :-(
Doing a similar install of 5.14 yeilds the same mess - From a fresh
install I can't even install Astro::Sunrise which is working happily
on my 5.8.2 server from when it was installed on 5.8.0!
Now you see why I am still using 5.8.2. It might be old and
unsupported, but it actually works - as long as I don't need a new
module - which I do :-( This mess all started when I decided I needed
to be able to generate graphs on the fly for web pages.

Have you tried manually downloading and untarring? I've not had the

No because there are so many dependencies. Perhaps you have kept your

No, but when I need another module I download the most recent version
of everything it depends on. Since I'm doing that manually it's an
iterative process, but it's only about 3 dozen..

Message-Id: <gpjvr7pc2bjv4dc4ps0hudmaafh77r0kv1@4ax.com>
When someone uses s browser and goes to a www.somesite.com/someperl.pl how does
it work at the server end? Let's say I'd like to create a "perl-clone" or
something like perl or php where would I get more info?

The web server will either return the raw contents of that page or, if
configured to do so, execute the file and instead return the output.
Again, this is a server specific configuration.

You'd like to design a new language? Jeez, kind of a big thing to do.
I'd start with the basics. Here is a free online book that I think is
really good and is very approachable if you already know Perl.
http://billhails.net/Book/
After you make it through that take what you learned and check out
some real life examples. There is no shortage of code for you to
go through in this area. Look at what Perl6, Jython, or PHP are
doing, for example.

There are a number of ways this /could/ work, but the simplest case
perhaps is CGI. It works like this:
1. The client user accesses http://example.com/script.cgi
2. The client browser constructs an HTTP header and perhaps body
3. The package is sent over the wire to some web server
4. The web server receives the HTTP request and parses it
5. The web server decides that 'cgi' represents a call to a script,
and hands it off to a script, invoking the Perl executable, and sends
the appropriate parameters
6. The Perl executable executes the script, accepting the parameters
as input and returning the appropriate results as output. This usually
consists of HTML, but could consists of other things and usually
involves some other kinds of machinations behind the scenes, like
running some SQL against a database and munging the SQL results
7. The web server receives the return value from the script and sends
it back down the wire to the client browser
8. The client browser renders the HTML, or does some else (like show a
Flash movie or play a wav file)
CC.

Thank you. I had looked at Perl Monks and not found this article.
