Perlmind Programming Journal (PMPJ) -- Sunday, April 12, 2015Sun.12.APR.2015 -- Mentifex AI moves into Perl.
Next we need to do a Google search-and-deploy mission for obtaining a viable version of the Perl language for our Acer Aspire One netbook running Windows XP home edition.
Ooh, sweet! When we search for "download Perl" on Google, we are immediately directed to http://www.perl.org/get.html which presents to us a choice among the Unix/Linux, MAC OS X, and Windows operating systems. Although we wish we were on 64-bit Linux so that we could be listed in a GNU/Linux AI website, we had better choose between ActiveState Perl and Strawberry Perl for our current Windows XP platform. Let's click on the link for Download Strawberry Perl because it is a 100% Open Source Perl for Windows without the need for binary packages. Perl.org recommends that we use the "latest stable version, currently 5.20.2." and Strawberry Perl 184.108.40.206 (32 bit) is offered to us. When we first click on the download, a Security Warning asks is whether we want to run or save this 68.6MB file. We click to save the file on our Acer Aspire One netbook. Huh? Almost instantaneously, after we see that the target will be our Acer C-drive, we get a pop-up window that says that we have completed a download not of 68.6 megabytes, but that we have downloaded 116KB in one second to C:\strawberry-perl-220.127.116.11-32bit.msi and we may now click on "Run" or "Open Folder" or "Close". Let us click on "Run" to see what happens. Now we get another Security Warning that "The publisher could not be verified. Are you sure you want to run this software?" Its name is "strawberry-per-18.104.22.168-32bit msi" and we can click on "Run" or "Don't Run". Let's click on "Run". It starts to show a green download transfer, but suddenly it stops and a "Windows Installer" message says, "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." So we go back to where we had the choice between "Run" and "Save" and this time we click "Run" instead of "Save." In a space of between two and three minutes, the package downloads into a "temporary folder." Then a Security Warning says, "The publisher could not be verified. Are you sure you want to run this software?" Let's click "Run." Now it says "preparing to install" and "wait for the set-up wizard." Finally it says "The Setup Wizard will install Strawberry Perl on your computer. Click Next to continue or Cancel to exit Setup." Well, I have a complaint. Why did the process not work when I tried to "Save" the download instead of merely "Running" it for what I was afraid would be one single time? Why is the process of installing Perl so obfuscated and so counter-intuitive? Well anyway, let's click on "Next" and get with the program. Next we have to click the checkbox for "I accept the terms in the License Agreement." Now for a Destination Folder the Strawberry Perl Setup says to "Click Next to install to the default folder or click Change to choose another." C:\Strawberry\ is good enough for Mentifex here. Then we "Click Install to begin the installation." Oops. "Error reading from file C:\Documents and Settings\Arthur\Local Settings\Temporary Internet Files\ Content.IR5\R6BYZW40\strawberry-perl-22.214.171.124-32bit.msi. Verify that the file exists and that you can access it." Now we have ended prematurely because of an error. Then we went back again to the initial download process and we went with "Run" instead of "Save," and wonder of wonders, we were able to download Perl. We will "Click the Finish button to exit the Setup Wizard," and we will read the Release Notes and the README file" available from the start menu. Aha! Upon clicking the Windows XP "start" button, we proceed into "All Programs" through "Strawberry Perl" to Strawberry Perl README in a Notepad file on-screen.Sun.12.APR.2015 -- Learning to program Perl Strong AI
http://learn.perl.org/first_steps says to check
that you have Perl installed by entering
perl -v and so we actually do
C:\Strawberry\perl -v and it works! It says "This is perl 5, version 20, subversion 2 (v5.20.2)" etc. Next with the MS-DOS make-directory "md" command we md perl_tests to create a "perl_tests" subdirectory.
Then we open the Notepad text editor and we create a file that
we call not hello_world.pl but rather mind0001.pl because
we want to start programming Perl artificial intelligence immediately.
C:\Strawberry>perl /path/to/perl_tests/mind0001.pl is what
we try to run. At first we get "No such file or directory" but when we
changed directory and entered
C:\Strawberry\perl_tests>perl mind0001.pl we saw:
hi mind0001.pl and so we have run our first Perlmind AI program.
