Polyglot (many languages) Test

A script I use on my server to test ALL the things.

Languages

• C (using both clang and gcc)
• Clojure
• CoffeeScript
• D
• Dart
• Erlang
• Go
• Hack
• Haskell
• Haxe
• Icon
• Io
• Java
• JavaScript
• Lua
• OCaml
• Perl
• PHP
• Python
• Ruby
• Rust
• Scala

By virtue of the fact that the test script is in BASH, that's being automatically tested as well.

Usage

Well... I use the script by executing /root/sandbox/lang/test-all.sh, but that only works because that BASH script is specifically written for my specific environment.

Environment

I'm running all of this on a $10/month DigitalOcean Droplet with Ubuntu 15.04. A lot of these are either languages that I installed with apt-get or they existed on the droplet already. Some were custom installed, and a couple (Haxe, Scala) were simply tar xvf'd right into the directory in which I'm running the test.

Future

I'm planning to change the paths to be variables, making it a bit more portable. I may do something with Chef to spread the love, and a Docker image would make a lot of sense. If you're interested in getting all of these languages working together on your system as I have on mine, feel free to reach out to me at DavidCanHelp.me

I also plan to flesh out the tests from bare-bones hello-worlds to idiomatic stubs that actually flex the muscles of each language just a wee bit more.

Why?

Because it's there.

Really, why?

I was tired of testing each environment with spot checks. Heck, I was tired of trying to remember where everything was. By putting a simple hello-world test into play for each language, I not only see whether everything is still working, but also have a quick reminder of how to jump back into that language/environment and get things going quickly when I need to use one. Mostly it's just a lot of fun, and relieves stress. If you've ever seen crap-tons of stuff flying past on my second monitor, that's probably been me monitoring the compilation of one of these languages while I get my work done. It's a good feeling to have them all working in a single box, and it builds confidence to know that I can reach for any one of these platforms and instantly get results without having to go through any configuration or remembering of first steps. Also, it demonstrates that I actually can get each one working smoothly and consistently over time on my own, so each language I've listed on my résumé (no, I don't have all of these listed -- just the ones I actually do know how to use in real-world situations for work) is backed up by proof you can touch with your own two hands. :D
