ming-ruby question

George Moschovitis

Hello everyone,

I would like to capture of Ming-Ruby in a Ruby String/StringIO.
I tried the following w/o success:

tmp = $stdout
flash = $stdout = StringIO.new
m.output
$stdout = tmp

The low level C output methods doesnt understand about
$stdout and keeps dumping bytes to the standard output.
Any ideas?

Thanks in advance for any help.
George.

Well this idea is a hack obviously but have you tried:

# mingout.rb
...
ming.output

# mingin.rb
m = IO::popen("mingout.rb")
data = m.read

The massive downside to this is that it requires two programs, and I
am sure there is
a better way, but it should work

Well I downloaded the ming source, and looked at the code for the
output method. It uses putchar() directly. You'd probably have to
patch the ming source and create a method that could use fputc( ) and
took a FILE* or something similiar (suitably wrapped up in a ruby
object) as an argument. Sorry
