Tar2RubyScript generates a standalone Ruby script from an existing directory, which contains a complete Ruby application (scripts, DLL's and resources). This standalone Ruby script can be converted to an executable with RubyScript2Exe. That's how I distribute all my applications, complete with resources, help files, licenses, readme, images, default configurations, everything. Even including the graphical front end (WXRuby or RubyWebDialogs [5]). And it just works... > Being able to easily include own media would also be very > nifty in my use case.

I did a test (on Linux) with the progressbar example. Yes, RubyScript2Exe detects progressbar.rb [1] and yes, it is included in the executable [2]. But when the executable is run, require\_gem only searches for progressbar.rb in its own dirs, not in the regular places. Resulting in an Gem::LoadError. If I catch this exception, it does work. See below. I'll have a look at it. Thanks. gegroet, Erik V.

This sounds cool. Anyone know what it would take to have this for OS X? It would be cool to be able to use RubyCocoa or TKRuby or QTRuby and then make it into an executable easily.

Resulting in an Gem::LoadError. require\_gem does not search for progressbar.rb. It searches for the progressbar \*gem\* (progressbar.rb gets required as a side effect if the gem specifies an autorequire file). Since you are not replicating the gems metadata structure in your packaged app, its not surprizing that it is not found. There are a couple of ways of attacking this. You /could/ replicate the gem metadata (not really recommended). Perhaps supplying a custom require\_gem that works in your packaged app. I think the only thing the custom require\_gem would need to do is do a require on that gems autorequire file (if any). Contact me (or another gem developer) if you need help pursuing this.

You need "FreePascal on the Macintosh" [1] and a machine with OS X. Since I'm the only developer of RubyScript2Exe and not possessing such a machine, it will probably never happen. Unless somebody is able and willing to do the porting... Or provides a SSH connection... I don't think it's to hard to do. > It would be cool to be able to use RubyCocoa or TKRuby or > QTRuby and then make it into an executable easily. The bindings for QT and TK are detected and included in the executable. QT and TK themselfs are not detected, because they have nothing to do with Ruby. They have to be installed manually. gegroet, Erik V.

Do you think tt may be good to have a gem-recommended way of dealing with this more broadly? With gems gaining wider use this could be useful for any app (rubscript, an IDE, etc.) that needs to know about ruby's directory structure, and hence about gems. ---

I did it once. It was something like this: api = Win32API.new(newlocation("file.dll"), "proc", %w(P P P P), "V") Newlocation the is path to "the internals of the package". (Of course, it's a temp dir...) But that only works when you directly access the DLL. Otherwise, when you access the DLL indirectly, you have to change the environment before starting the child process. Could be done with: ENV["PATH"] = newlocation("bin/in/package").gsub(/\//, "\\\\") + ";" + ENV["PATH"] system("command") You might have to combine them: ENV["PATH"] = newlocation("bin/in/package").gsub(/\//, "\\\\") + ";" + ENV["PATH"] api = Win32API.new(newlocation("file.dll"), "proc", %w(P P P P), "V") Not tested. Just an idea. gegroet, Erik V. ---

RubyScript2Exe executes the application, in order to trace it, with (simplified): $ ruby -r require2lib app.rb This require2lib sets an at\_exit block. In this block, all required and loaded files are copied to ./lib . This ./lib is packed into the executable and recreated on the destination machine just before doing something like: $ ruby -I ./lib app.rb That's part of the job RubyScript2Exe does to satisfy the requirements (besides ruby.exe and ruby.dll and a bunch of recursively determined dll's en so's). This copying works for files required via require\_gem as well, because the old require is still done by require\_gem, so they show up in $". Checked that. It works. It's just that rubygems.rb doesn't work properly on the targeted machine, because it expects its own environment, which is not recreated. My plan was to overwrite this rubygems.rb which a version of my own, only implementing require\_gem. I came up with the code below. Any RubyGems hackers willing to have a look at it? Just shoot...

If you don't care what version you get, just do a normal require. In addition, you need to make sure the rubygems library is loaded. You can do this by: \* explicitly requiring 'rubygems' before requiring any file   that would be in a gem.[1] \* explicitly starting ruby with a -rubygems command line option. \* Setting the RUBYOPT environment variable to 'rubygems' If you /do/ care about which the version of a gem you are using, then use a require\_gem command with explicit versioning requirements. Again, make sure the rubygems library is loaded using one of the above three techniques. Regarding your GEM\_PATH comment, I'm not sure what you are getting at. GEM\_PATH is for specifying where multiple gem repositories are locally stored.

Coincidently, on the rubygems-dev mailing list we just had a discussion on the value of identifying an "API" for gems that identifies some kind of programatic interface for doing gem related things. These kinds of operations certainly fall into that category. Thanks for the feedback. We certainly want to head in that direction. > **···** > > -- > -- Jim Weirich jim@weirichhouse.org [http://onestepback.org](http://onestepback.org) > ----------------------------------------------------------------- > "Beware of bugs in the above code; I have only proved it correct, > not tried it." -- Donald Knuth (in a memo to Peter van Emde Boas) ---

I'm just require()ing a Ruby library (C++ extension) that is dynamically linked against a few DLLs. One of those is fmod.dll, but there's also msvcp71.dll and msvcr71.dll and a custom one involved. I know that RubyScript2Exe is already able to bundle the DLLs that Ruby uses so an option for adding the specified DLLs in a similar way would be just what I need. I'm not sure if this involves doing a Win32-API call to tell Ruby to also look for DLLs at the location the executable was unpacked to. Does this sound possible? Thanks a lot for helping out with this. [Next page](https://rubytalk.org/t/ann-rubyscript2exe-0-2-0/15204.md?page=2)
