[ANN] RubyInline 1.0.6 Released

RubyInline 1.0.6 has been released!

Ruby Inline is my quick attempt to create an analog to Perl’s
Inline::C. It allows you to embed C external module code in your ruby
script directly. The code is compiled and run on the fly when needed.
The ruby version isn’t near as feature-full as the perl version, but it
is neat!

Changes:

  • Added a prelude argument for header and datatype declarations.
  • Only output stuff if invoked verbose (ie ‘ruby -v ./example.rb’).
  • Added some compatibility code for windows.
  • Declared requirement on POSIX system.

Very neat !

  • Added a prelude argument for header and datatype declarations.

Can you please show with an example how to use the “prelude” argument.
My (dumb) attempt was :

inline args, ‘#include <stdio.h>’,<<-END
…
END

But then what if I have multiple lines in the prelude?

  • Added some compatibility code for windows.

I hate to bother you again …but I couldn’t make it work on Windows XP
(Home Edition).
I got this message:

Patch below for better error messages if the inline code fails to
compile:

  • Added a prelude argument for header and datatype declarations.

Can you please show with an example how to use the “prelude” argument.
My (dumb) attempt was :

inline args, ‘#include <stdio.h>’,<<-END
…
END

But then what if I have multiple lines in the prelude?

Either:

  • embed \n in a double quoted (or other form of interpreted) string.
  • just have a multi line string
  • use the heredoc style string as above, but w/ a variable above the
    inline call…

I got this message:

Define INLINEDIR or HOME in your environment. Better yet, get cygwin
and run in a POSIX environment. Windows does too many things on too
many platforms and I own NONE of them to test on.

Yes, that was a natural extension of my earlier attempt and I tried that.

That worked too ! Thanks…

Got it …now it is working.

Better yet, get cygwin and run in a POSIX environment.

I can definitely do that at home … but I do not have that option at work.

Windows does too many things on too many platforms and I own NONE of them
to test on.

I agree … no problem.

Again, thanks for coming up this neat utility.
