在同一个脚本上运行两个不同的解释器

我有一个用Ironruby编写的脚本,它使用C#.dll来检索哈希。然后我在其余的Ruby代码中使用该哈希。我宁愿不从Ironruby解释器运行我的整个脚本。无论如何在IR解释器上运行一段代码,获取哈希值,并通过常规Ruby解释器执行其余的代码?

一种可能的解决方案是将脚本分成两部分, 铁红宝石执行的第一部分必须将他的状态保存在yaml文件中,然后将控制权交给第二部分,这部分将由ruby运行

这是一个小型演示:

C:\devkit\home\demo>demo
"running program:demo_ir.rb"
"the first part of the script running by the iron_ruby interpreter"
"my_hash attributes:"
"attr1: first value"
"attr2: second value"
"attr3: 2012"
"hash_store_filename:temp.yaml"
"running program:demo_ruby.rb"
"hash_store_filename:temp.yaml"
"the second part of the script running by ruby 1.8.x interpreter"
"my_hash attributes:"
"attr1: first value"
"attr2: second value"
"attr3: 2012"

这里是ironruby(demo_ir.rb)第一部分的来源:

require "yaml"
p "running program:#{$0}"
hash_store_filename = ARGV[0]

my_hash = { attr1: 'first value', attr2: 'second value', attr3: 2012}

p "the first part of the script running by the iron_ruby interpreter" 
p "my_hash attributes:"
p "attr1: #{my_hash[:attr1]}"
p "attr2: #{my_hash[:attr2]}"
p "attr3: #{my_hash[:attr3]}"

# save the state of the script in an array where my_hash is the first element
p "hash_store_filename:#{hash_store_filename}"
File.open( hash_store_filename, 'w' ) do |out|
  YAML.dump( [my_hash], out )
end

这里是ruby 1.8(demo_ruby.rb)第二部分的代码

require "yaml"
p "running program:#{$0}"
hash_store_filename = ARGV[0]
p "hash_store_filename:#{hash_store_filename}"
ar = YAML.load_file(hash_store_filename)
my_hash=ar[0]

p "the second part of the script running by ruby 1.8.x interpreter"
p "my_hash attributes:"
p "attr1: #{my_hash[:attr1]}"
p "attr2: #{my_hash[:attr2]}"
p "attr3: #{my_hash[:attr3]}"

和发射器:

@ECHO OFF
REM file: demo.bat
SET TEMP_YAML=temp.yaml
ir demo_ir.rb %TEMP_YAML%
ruby demo_ruby.rb %TEMP_YAML%
del %TEMP_YAML%

如果在并发环境中运行脚本,则可以在ironruby脚本中生成yaml文件的唯一临时名称,避免两个进程(或线程)尝试写入相同的文件。

如果您愿意,可以使用一些C#代码行而不是.bat来集成脚本的两个部分,但这有点困难(恕我直言)

我使用以下方法成功测试了此解决方案:

C:\devkit\home\demo>ir -v
IronRuby 1.1.3.0 on .NET 4.0.30319.239

C:\devkit\home\demo>ruby -v
ruby 1.8.7 (2011-12-28 patchlevel 357) [i386-mingw32]
