Hello All,

Uptil now I have been coding fairly simple Perl scripts.

Lately I have started designing some complex scripts. And I always felt that
if you place the logic and flow of the script on paper first then coding
part is simplified to a great extent. And uptil now I have mainly used pen
and paper for it. :)

Was just wondering if there is any graphical tool (of course opensource :))
specific to Perl to design the flow of the Perl script projects before we
actually start coding it.

Using it I should be able to design something similar to flowcharts and
should be able to share it with others to get it reviewed.

So just wanted to know which tool does Perl developers use in general to
design the flow of the Perl projects.

Cheers,
Parag


“Show me your flowcharts and conceal your tables, and I shall continue
to be mystified. Show me your tables, and I won’t usually need your
flowcharts; they’ll be obvious.”

A lot of my work is data munging so YMMV. But when I start coding, I
write down the data structure of the input and the data structure of the
output. I then create any required internal data structures. After
that, it's as the man said, it becomes obvious; it's just a matter of
connecting the dots.

Of course, knowing how to build complex data structures in Perl is a big
plus. See these perldocs for help:

perldata http://perldoc.perl.org/perldata.html
perldsc http://perldoc.perl.org/perldsc.html
perllol http://perldoc.perl.org/perllol.html

The general rule of thumb is: if the order is important, use an array;
otherwise use a hash.

Also, don't store more than one reference to an item in your data
structures. This can cause circular references. Use the hash key (or
array index) to indirect link items.

Programming is as much about organization and communication
as it is about coding.

I like Perl; it's the only language where you can bless your
thingy.
