ANN: TKXXS, a very simple "GUI"

Ruby
1

Happy new year!

TKXXS provides a very simple and very easy to use GUI (graphical user
interface) for Ruby. It gives you a persistent output window and popping
up (modal) dialogs for input. For a screenshot, see:

Tested on Windows, only.

Homepage: GitHub - Axel2/tkxxs: TKXXS provides a very simple and very easy to use GUI for Ruby

Prerequisites:
Ruby 1.8.7 or 1.9.x with TK (e.g. RubyInstaller)

Install:
gem install Platform
gem install tkxxs

Based on TK.

I was trying out the library in ruby. It had an issue of missing ‘tk’
library. And i found this error:

/usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- tk (LoadError) from /usr/local/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in require’

I believe my system as tcl/tk. Am i missing anything else? Can you
suggest
me some command to verify my TCL/TK installation.

Oh sorry for not including much information in my previous mail.

I was trying out the library in linux (ubunutu).

Ruby version: ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]

Hi,

I believe my system as tcl/tk. Am i missing anything else? Can you
suggest
me some command to verify my TCL/TK installation.

  • Which OS (Windows xxx, Linux, …) are you using?
  • Which Ruby-Version do you use?
  • Did you use RubyInstaller? (Downloads)
    ** If yes, did you use the exe-Installer (As opposed to 7z)? Then you
    must have clicked something like " …activate tcltk… "
    ** Do you have this directory: <your_ruby_path>\lib\ruby\1.9.1\tk
    ** Do you have this file:
    <your_ruby_path>\lib\ruby\1.9.1\i386-mingw32\tcltklib.so

Maybe you must replace “1.9.1” to “1.8.7” or whatever you use.

BTW, it is easy to install Ruby with tcltk support using the
RubyInstaller.

I tested it only on Windows, but I’m not aware of things which are
OS-dependent (but I wrote the code in 2010, maybe I overlooked
something.)

This line of your error-message is quite obvious:
“…cannot load such file – tk (LoadError)…”
Seems, that you have not tk.

You can create a file tmp001.rb with the following content.

require ‘tk’
require ‘tkextlib/tile’

and run it with your ruby. Which message do you get?

Yes, it seems the tk library is missing. But i tried gem install tk, but
it
said there no such file.

I think I found an answer to your question:

“…On Ubuntu, there is a libtcltk-ruby package…”

I found it here: https://www.ruby-forum.com/topic/441820

A better first command could be:
gem q -r -n tk

-> q(uery) r(emote) n(ame matches) tk

But right, this doesn’t give a tk-gem.

I don’t know much about linux, but does your Ubuntu have something like
a “package manager” for software? Does this show tk for ruby?
