Ruby language support

Daniils Kostornijs

Today I've received my Onion and extensions pack. Thanks a lot for a wonderful product! Extremely well done!
I would like to know if you have any plans for Ruby language wrappers for GPIO and extensions? There is no need for exact release date, just say if you have them in plan or not

P.S. You must by damn busy trying to polish all the things and release new features, but it would be nice if you could publish some roadmap for the Onion feature.

Thanks once again!

Yeah, Ruby is in our roadmap. We are just focusing on the wrapper for Python and NodeJS for now. Once those are done, we'll be working on the wrappers for PHP and Ruby.

You can start with just falling back to terminal commands until the library is ready

First, install Ruby

opkg update
opkg install ruby ruby-irb

Then do something like this

root@Omega-271C:~# irb
irb(main):001:0> `fast-gpio read 8`
=> "> Read GPIO8: 1\n"
irb(main):002:0> `fast-gpio set 8 0`
=> "> Set GPIO8: 0\n"
irb(main):003:0> `fast-gpio read 8`
=> "> Read GPIO8: 0\n"
irb(main):004:0> `fast-gpio set 8 1`
=> "> Set GPIO8: 1\n"
irb(main):005:0> `fast-gpio read 8`
=> "> Read GPIO8: 1\n"

Then you can wrap it in a function to abstract it away

irb(main):007:0> def gpio_read(pin)
irb(main):008:1> `fast-gpio read #{pin}`.split.last == "1"
irb(main):009:1> end
=> :gpio_read
irb(main):010:0> gpio_read(8)
=> false

I guess i could quickly build a thin lib for this. will let you know if I do.

After installing ruby, I've taken up 68% of space.
I think i only explicitly installed ruby, ruby-readline, ruby-openssl, ruby-irb and ruby-gems. Other packages were sucked in as dependencies.

Andrei - I don't know if this helps, but your comments were so helpful I wanted to mention this. I've had ruby installed and didn't see a lot of additional dependencies. I just now installed ruby-irb and saw that opkg installed a whole bunch of ruby-related stuff.
