Help with Ruby.

FurySh0ck · Nov 26, 2016

Hello friends! I post this on the off to pic because I can't really find a fitting sub-forum. If you know a better place I can post this thread, please let me know.
I want ruby and Ruby gems to run on my android device (galaxy S4 GT-I9515, not that it matters). I know android is Linux based so there shouldn't be a problem doing this.
Basically, I don't want to use Ruby for development, I just need to use some of it's applications (gems).
I tried ruboto core and ruboto IRB, but couldn't install a gem.

In general, my android won't read "apt-get" command in terminal. I don't know why.
If anyone could help me to run some Ruby gems on my device, I would really appreciate it. Thanks for people who answer!

Android is a Linux kernel, however it is not a full Linux like Debian or Ubuntu.
Android doesn't have a package manager by default (unless with Google Play or other app markets). It doesn't have apt-get.
However, I can say that there's a terminal called Termux in Google Play or F-Droid.
It does have apt and it doesn't require root.
I found Ruby in the apt repos of Termux though.

Code:

$ apt list | grep ruby

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

ruby/stable 2.3.3 arm
ruby-dev/stable 2.3.3 arm
ruby-ri/stable 2.3.3 all

First of all thanks for the reply!
So, in order to use ruby on android all I have to do is use a more linux-like terminal, and use the command "$ apt list | grep ruby", am I right?
Will I have access to apt-get and commands like that with the new terminal?

Termux is not really more Linux like, it's still using the same kernel. It downloads a core (other applications, etc) to /data folder. That's how it works.
You will have access to apt in the new terminal. However, there is not much packages in the repo as your Android device is ARM and the packages have to be built into a package file. If you'd like the full experience, consider using a KVM or Xen VPS which run full on distributions (Debian, Ubuntu, etc). They also have more packages over there.
Now to install Ruby, you wouldn't apt list. What you would do in Termux:

Code:

apt install ruby

would install Ruby and you would be able to use it and install gems.
I installed Ruby with that command and confirmed it works:

Code:

$ apt install ruby

When I ran the

Awesome! It worked well and neat. +1 For your Thanks-o'-meter.
Now I have some questions about termux, if you could answer:
1) Where does it save all the files? I used

Code:

 apt update

and I am going to download packages from now on. I think I should know where it goes / how can I change that save directory.
2) When I tried using root permissions (you know, my device is rooted so I used

Code:

su

in order to gain access) I couldn't use apt commands anymore. I think some of my ruby gems will require root permissions, so I would like further explanation about it (only if you could of course

)

1. It saves inside app data, specific folder is /data/data/com.termux/files/usr/var/cache/apt
2. I don't think su works in Termux really, however my root doesn't work right now so I can't really say a definite answer.

That's all I had to ask in this thread.
