Thank You

It already supports Ruby Gems!

[sal]

how?
I tried the ruby way without success

[sal]

Code: Select all

gem install mysql
gem install sqlite3-ruby
gem list


how do i accomplish this ?


mr DSP how do you install and use gems?

Code: Select all

gem install mysql
gem install sqlite3-ruby
gem list

How do I accomplish this ?

Have you tried to install the gems manually?

yes i tried that, but at the moment the use of gems is not allowed as confirmed by dsp robotics on pm due to bugs caused by gems on windows platform.
Hope they will find a solution at least for adding database connectivity and network usage.

Oh, OK, cheers.

Sal - here's the workaround to get Gems working inside FS.
As said before many of the Gems will not work on Windows!

FOR ADVANCED PROGRAMMERS ONLY!!!

Step 1) Install Ruby on your PC

In order for this to work it needs to be a mswin32 compiled version of Ruby not a ming32 version.

Try this: http://www.dsprobotics.com/Files/Ruby192MSwin.zip

Just copy the folder to somewhere on your PC, you can also have the ming32 one installed in a different folder.

Check: Ruby -v

Should say something like: i386-mswin32

Step 2) Create a shortcut on your desktop

Right click - shortcut etc.

Use this string: C:\WINDOWS\system32\cmd.exe /E:ON /K D:\Ruby192MSwin\bin\setrbvars.bat

but remember to modify the path to match your ruby installation.

Step 3) download Install Gem on your system:

Put the downloaded gem in the gem folder: D:\Ruby192MSwin\lib\ruby\gems\1.9.1\gems (using your own path)

then in Ruby:

gem install gemname

You should see the gem install:

Step 4) Add the new path to FlowStone's ruby

Open FS2 and enter something like this into a Ruby edit module:

$LOAD_PATH << "D:/Ruby192MSwin/lib/ruby/gems/1.9.1/gems/myGemFolder"

Remembering to use / not \

This only has to be done once!

Step 4) Test Gem

Start with a new Ruby Edit module and test if it loads:

ie. require 'MyGemName'

Results: the first time it load you get a result of True, from then on False - both are good it has been loaded!

If the loaded gem causes a crash then it is the gem that doesn't work on Windows NOT FlowStone!

Thanks 'DSP' for you help on this..

Embedded - You're welcome, glad I could help...

Also worth mentioning is that gems are all the rage, but on Windows dll's have been doing these things for years.

dlls work perfectly with FlowStone V2 & Ruby on Windows, so if you have any specific need it's probably more reliable to just make a call to the dll.

i have already tested this but for example this simple sock call

Code: Select all

require'socket'
#Socket.ip_address_list
Addrinfo.udp("192.168.0.2", 10001).bind {|s|
  p s.recv(10) #=> "hello"
}

stop the ruby code
""Execessive processing detected...etc.etc"

and even this

require 'Win32API'

Code: Select all

getForegroundWindow = Win32API.new('user32', 'GetForegroundWindow', 'V', 'L')
window_handle = getForegroundWindow.Call()
getWindowText = Win32API.new('user32', 'GetWindowText', 'LP', 'I')
title_buffer = ' ' * 512
getWindowText.Call(window_handle, title_buffer,512)
title_buffer

but the oddity is that, by removing the buffer size, working
getWindowText.Call(window_handle, title_buffer,512)
getWindowText.Call(window_handle, title_buffer)

Code: Select all

getForegroundWindow = Win32API.new('user32', 'GetForegroundWindow', 'V', 'L')
window_handle = getForegroundWindow.Call()
getWindowText = Win32API.new('user32', 'GetWindowText', 'LP', 'I')
title_buffer = ' ' * 512
getWindowText.Call(window_handle, title_buffer)
title_buffer
