Rubyscript2Exe directory management

I’d like to use rubyscript2exe to move over a Ruby application and its
environment to a production box that will be run by a sysadmin. As such
he needs some control over things like where the app installs itself,
and the ability to modify the config.yml file I’ve associated with the
app. I don’t really have a handle on what I can and can’t control.
This is a windows box, by the way.

For instance, the app and everything about it seems to install itself
relative to c:\documents and settings\user\local settings… blah blah
blah. I would rather be able to tell it exactly where to uninstall
itself. Possible? I suppose I can set the TEMP environment variable,
but that seems like a hack that I wouldn’t be too excited to write in
the official instructions.

Second, I can’t “just extract” the app. I try running with the
–eee-just-extract flag and I get this: COuldn’t create directory
c:\temp\C:/ApplicationDirectory

where c:\ApplicationDirectory is what my present working directory was
when I ran the original rubyscript2exe executable. Just thinking aloud,
can I manipulate either the appdir or userdir variable during the
is_compiling phase to change this? How do I make the extra C:\ go away
so it is a legal directory?

Is there any way to tell the app that it’s ok to use the directories
specified? For instance in my config.yml file if I want to say datadir:
d:\client\data\ftp or something like that, I can’t seem to get it to
work properly. I think it is looking for this directory relative to the
temp area where the app installed itself, which is not what I want.

Thanks for any help!

Ok, not really sure what changed on me, but I’m getting different
results now. I can run --eee-justextract on my application and it does
successfully explode itself into the current directory. I could swear
that it tried to extract itself into the temp directory yesterday, I did
not imagine that nested C:\ error message :).

But now my error has changed. When I run the app directly as an
executable (something I don’t want to do, because my operations guy
wants this thing to have a permanent home, not extract itself as
needed), it runs. But when I extract it first and then run it, it keeps
telling me some key gems I need are missing. ActiveRecord, for one:

./lib/rubygems.rb:251:in report_activate_error': Could not find RubyGem activer ecord (>= 0.0.0) (Gem::LoadError) from ./lib/rubygems.rb:188:inactivate’
from ./lib/rubygems.rb:66:in active_gem_with_options' from ./lib/rubygems.rb:59:inrequire_gem’

from ./lib/rubygems/custom_require.rb:27:in
gem_original_require' from ./lib/rubygems/custom_require.rb:27:inrequire’
from app/init.rb:39

Which is where because, from what I can see, it’s in there:

Directory of C:\bla\lib\rubyscript2exe.gems\gems\activerecord-1.14.4

I am specifying the -I lib\ parameter, as described in the instructions:

bin\ruby -I lib\ app\init.rb

I know it’s in there and works, because as I said, when I don’t extract,
it works fine. Could it be extracting into the wrong place or
something? This happened with a number of other libraries (pdf-writer,
rubyzip) but through some juggling of directories and additional -I
parameters I made those go away. But I’m stuck on activerecord now.

It’s only possible to use a fixed directory name in %TEMP%. You
can’t specify a full path. But it probably isn’t too hard to
implement. I’ll consider it.

You did “–eee-justextract” instead of “–eee-just-extract”…
;] The former works; the latter doesn’t.

I could swear that it tried to extract itself into the temp
directory yesterday, I did not imagine that nested C:\ error
message :).

“c:\temp\C:/ApplicationDirectory” probably was a result of
running “–eee-just-extract” in combination with
“RUBYSCRIPT2EXE.tempdir=‘C:/ApplicationDirectory’”. Debugging
isn’t easy when making 2 errors at the same time… ;]

where c:\ApplicationDirectory is what my present working
directory was when I ran the original rubyscript2exe
executable.

Sorry, should be “3 errors”… ;] You probably thought that
“c:\ApplicationDirectory” was there because it was the current
directory, although it probably was there because you specified
it in your code. But I’m not sure, it’s just a guess.

I am specifying the -I lib\ parameter, as described in the
instructions:

bin\ruby -I lib\ app\init.rb

That’s not correct, anymore. (As usual, code is faster than
documentation…) It should be (on Windows):

bin\ruby -r .\bootstrap.rb -T1 empty.rb .\app\yourscript.rb

This bootstrap.rb sets up the (fake) RubyGems environment.

Thanks.
