Building
Blocks in PERL
All of the programs I have
poseted here are very simple. Even an average webmaster with no
perl experience should be able to install and modify any of them
without much trouble.
But the concept is that each
is a building block in a bigger project.
There is nothing comlex about
perl. It is very basic, very litteral and very deliberate. You
tell it to add 2 numbers and if the vale is greater than 10 do
one thing or else do something else. You don't have to be a
programer to understand that or work with that logic.
If you can relate to simple
math and follow directions, you can program in perl.
Although each of the programs
offered free here are simple, when you add them all together they
can form a much more complex program.
That is what programing is all
about.
You start off with a program
like the simple search. You add a sub routine to sort the sesults
into alphabetical order. Now the program is more complex. Add
more and more and then add a few lines from the RSS fetch and
print and add in pages from outside websites.
Now you use the fetch and
print to access other websites and write the files to a database
and the simple search reads those files.
You are progressivly building
a search engine like google by combining the basic ideas each of
the building blocks offers.
If you think in small pieces
and build in baby steps, you can reach amazing heights.
All you need is some basic
building blocks which can be found here at bumblebeeware.com as
well as hundreds of other sites offering free perl scripts.
