Re: Lua scripting language

You could try this - http://andre-simon.de/doku/rpi_gpio_lua ... io_lua.php - I don't have lua installed on my Raspberry Pi so I don't know how well it works.

Re: ruby 2.0.0 installation

I downloaded the 2.2.1 source from https://www.ruby-lang.org/en/downloads/ using Epiphany. Clicking on the link for the source code for Ruby 2.2.1. When it was downloaded, the extract window popped up and I extracted. The suggested location would be fine: pi/downloads/ruby-2.2.1 Next I opened the te...

Re: ruby 2.0.0 installation

Actually, I believe that Ruby 1.9.3 code will run happily under Ruby 2+. As I understand, the main changes between Ruby 1.9 and Ruby 2.0 are some additions to the language and the default encoding for text encoding being changed to UTF-8. To check, I installed Ruby 2.2.1 on a Raspberry Pi by downloa...

Re: ruby 2.0.0 installation

You could install Ruby 2.0.0 using one of the popular version managers, RVM or Rbenv. This would allow you to keep the installed Ruby untouched and switch between it and Ruby 2.0.0 as you wish. There is a little bit of "fiddling around" to install them so it wouldn't be an ideal solution unless you ...

Re: Some success with Java/JRuby

Many thanks for that link Rich. Actually I did finally manage to install JRuby but I didn't leave a note here.

This is how I did it: http://peterwawood.blogspot.com/2014/09 ... ry-pi.html

Re: How to Run Tests in Command Line Wolfram

I asked a similar question on the Wolfram Raspberry Pi forum. The answer was that Munit is not in the current Raspberry Pi release and that it may be in a future one.

I do hope so.

Re: How to Run Tests in Command Line Wolfram

The unit tests also appear to be missing from the Notebooks too. I get the same "Get::noopen: Cannot open MUnitLoader`." message.

How to Run Tests in Command Line Wolfram

Is it possible to write Wolfram tests using the Wolfram command line. When I tried I got this message and the tests didn't run: Wolfram Language (Raspberry Pi Pilot Release) Copyright 1988-2014 Wolfram Research Information & help: wolfram.com/raspi In[1]:= VerificationTest[Sin[E]>Cos[E]] Get::noopen...

Re: Remove Ruby compiled from source

The script that you linked to will install rbenv, a method to manage multiple versions on Ruby . There is no need to remove the existing version of Ruby prior to installing first.
