RScript22

IActiveScript implementation for Ruby2.x both Win32/Win64 MT

• IActiveScript interface for ruby interpreter
  • It can write ruby code as embeded script. For example HTA (Html application).
• Rubyizer
  • Rubyizer is simple COM object that exports ruby object into the caller's environment.

Rubyizer

Rubyize example

The below VBScript code illustrates the power of Rubyizer.

'test.vbs
set r = CreateObject("ruby.object.2.2")
WSH.echo r.RubyVersion  '=>2.2.0-p0 (x64-mswin64_100)
Set reg = r.erubyize("/\Azb(\d+)(a?)C/")
Set m = reg.match("zb321aC")
If Not m Is Nothing Then
  group = m.to_a
  WSH.echo "match:" & group(0)      '=>zb321aC
  WSH.echo "1st group:" & group(1)  '=>321
  WSH.echo "2nd group:" & group(2)  '=>a
End If

description

• line 2 : instantiate Rubyizer
• line 4 : Rubyizer#erubyize evaluates the string argument as Ruby script and returns the evaluated value as an object. In this sample code, the argument is a ruby's Regexp literal, therefore the returned value is Regexp object.
• line 5 : send 'match' to the Regex object and set the result object to a variable 'm'.
• line 7 : get the result array from Match object and set it to a variable 'group'.
• line 8 : Because 'group' is VBScript's array, it can accessed its element with (index) syntax.

Rubyizer methods

Rubyizer#rubyize

convert the argument to the rubyized object.

set r = CreateObject("ruby.object.2.2")
set num = r.rubyize(3)  ' get ruby Fixnum object
WSH.echo num.next       ' => 4 

Rubyizer#erubyize
