Issue #477 - 2020-09-14 - GUI with Perl Tk

latest | archive | by Gabor Szabo
Don't miss the next issue!

Hi,

You might recall a long time ago I started a project called Padre, the Perl IDE that was, in its time, a fairly popular project. Unfortunately with time all the contributors moved to other projects and some of them to other programming languages. Now the project is dormant.

However, I remember how much fun it was to build a GUI and thus after so many years I am back with another, albeit much less ambitious GUI project. One goal is to make it easier for you to decide on your PerlTidy configuration options, that will generate your favorite layout of code. The second goal is to create a set of Perl Tk examples and videos explaining it to make it easier to you too to create Perl Tk based GUIs.

I also hope that some of you will find this project a good reason to support yours truly.

Enjoy your week!

Gabor Szabo
