I originally wrote AFT in awk (sometime during the early/mid 1990s) . I ported it to Perl by using the awk to perl translator (a2p) as a starting point.
Every once in a while I revisit AFT to see if there are any new tricks to add or just to clean up the code and make it a bit more Modern Perl. AFT is still in the Ubuntu software repository, so you can install it under Ubuntu by simply doing sudo apt-get install aft.
I'm still using Perl. I am doing some funky stuff with the AWS cloud (EC2 instances) and find Lincoln D. Stein's VM::EC2 package fits my needs. Perl is still great for replacing nasty bash/sh scripts (although some would say I am replacing the nastiness of bash with nastiness of Perl).
I'm not much of a CPAN user, but those who know me understand that I am very selective of libraries and frameworks. I prefer to avoid layering and loading lots of dependencies. What I find attractive about Perl is how much the basic distribution can get accomplished (e.g. I don't have to resort to libraries so quickly as when I program in Lua).
I'm particularly interested in investigating Mojolicious for use in my elderly monitoring project. I use LuaJIT primarily on the base station (with a bit of Erlang). The cloud side is currently a fair amount of Perl. But aren't there better languages to do cloud/web development? Isn't Perl old hat?
For those folk who think that Perl is old hat and doesn't have a place in the modern Web, do you use DuckDuckGo? It was developed primarily in Perl....
