Instantrails users - Sep 2006 - An absolute minimal install of ruby and rails.

Hello All.

I am trying to distribute rails apps to several windows servers.  I
don''t want to install and update a separate ruby install on each
machine so I was thinking about using ifolders as a deployment tool.
Ifolders is a wonderful product but occationally it has problems
syncronizing large amounts of data.

What I would like to do is to deploy the smallest subset of ruby
including all the site libs and gems and maybe apache (not really
required because I can use mongrel).

Would it work to simply copy the bin and lib directories of the
allinone/ruby tree? Can I do anything to clear out the older libs and
gems? Can I clear the cache? what is the best way to set the path on
the machines?

Any advice would be much appreciated.

Thanks.

Yes, the bin and lib directories are the only thing you need out of the ruby
dir. Also, you can go to the command line and "gem uninstall fxruby"
because
you won''t need that and its pretty big.

Here is what I have done so far.

I copied the ruby directory from instantrails into another directory.
I deleted all the directories except for bin and lib.
I opened up a command prompt and set my path to the new directory and
nothing else.
I did a gem clean and it cleaned up all the old gems IN THE NEW
DIRECTORY!. (ruby rocks)
I then did a gem uninstall fxruby.
Then I manually went in and cleared the cache directory and the
gems/doc directory.

At the end of all this I have 29.5 megs of stuff in 3219 files.  Each
gem has it''s own doc directory and I suppose I can delete those too to
get a little more space.

Here is my problem though. All the cmd files in the bin directory have
hard coded paths in them of where instantrails used to be. For example
the cap.cmd says @ruby "D:/InstantRails/ruby/bin/cap" %*

That''s not good. I want this app to be totally portable so there
should be no absolute paths at all.  I suppose I could set some
environment variable or something. Is there a better way to do this?
Does the windows command line have any equivalent of __FILE__?

"When you run InstantRails.exe in a new directory, he''ll detect
that
and update all of those paths to the new location."

Here is a cool trick I cooked up. Feel free to grab it and pass it on.

I have written the following batch file, the REMs explain what is
going on. This would work for most scripts I would think. You could
expand it by doing even more trickery if you wanted to.
.
-----------------SNIP-------------------------------
@REM  Generic Batch file for running ruby scripts
@REM  This file takes it''s name, strips off the
''.cmd'' at the end
@REM   and then passes the remaining to the ruby executable in it''s
own directory.
@REM   It should be used in the ruby/bin directory.
@REM
@REM   EXAMPLE:  if you wanted to run the cap script in the ruby/bin directory
@REM              you would copy this batch file to a file called cap.cmd.
@REM              this way you could set up a .cmd file for all the
ruby scripts in your ruby/bin

@set BINPATH=%~dp0
@set RUBY=%BINPATH%ruby
@set FILENAME=%~nx0
@set SCRIPTNAME=%FILENAME:~0,-4%

%RUBY% "%BINPATH%%SCRIPTNAME%" %*

Nice!  Is that a bat file or a cmd file? Will this run on both Win 2000 and
XP?

I wrote it as a CMD file on XP. According to the documentation it
should also work on windows 2000 and NT. I am not sure if it will work
 run on 95 and I have no way of testing it.
