Is there anything you comp.lang.ruby readers would recommend that would
abstract away things like "if file load fails" or "if file not found" or
"index of all .xml -files in the subdirs"?

I can do the rescue patrol -mission, but time is running out! Lost on
the Apache mountain. I am not sure my squad will get us there on time...

Not looking for anything big, preferably small and simple (ie. practical).

Thanks

I am not sure what you are missing. You can do

File.open("foo") do |io|
end resuce nil

if File.exists? "foo"

xml_files = Dir["bas/**/*.xml"]

Which is pretty small I'd say. What am I missing?

Kind regards

robert

I admint! I is dummy! IT's easy! 8)

Dir['/home/kasbah/*.jpg' && '/home/kasbah/*.png'].sort!.each { |f| puts
f.to_s }

But then its not that short:

if File.exists? $imgSourcePathStr
if File.exists? $imgDestPathStr
indexedDirs = indexImagesInDirs
($imgSourcePathStrs, $imgDestPathStr)
else
puts "no dest!"
exit
end
else
puts "no src!"
exit
end

indexedDirs.each { |one|
path=one[0]
num=0
one.flatten!.length < 8 ? num = (one.length.to_i-1) : num = 7
num.times { |m|
puts "converting (" + (m+1).to_s + "/" + num.to_s + ")"
imgname = one[(m+1)]
savesubpath = path.split("/").last
saveresized = savetargetstr.to_s + "/" + path.split("/").last + "/" +
(m+1).to_s + "fullsize" + imageFormat
#and then write and FAIL..
#Double slash kills..
#Or directory doesnt exist!
#Its all too complicated
#I is dum!
}
}

I think the lines above are more easily handled if you use the methods
in the core File library, such as File.basename etc. Much to choose from
there.

Yes. I was oblivious to File.basename which was exactly what I was
looking for. Thank you for pushing me in the right direction!

But I was not waste of time! I twas gathering cases for file ops. IT's
easy! 8)

Here's what I got, minimal case plan
- Open file
- Create file that doesn't exist, open
- Save file
- Overwrite file
- Dir doesnt exist, create
- get filename from path str (file.basename).
- get the sub dir file is ("deepest" dir)
- remove dbl slashes (etc crap).
- nonrelative dir (remove /dir1/../dir1/ etc.)

I was looking for guide covering these on google. Didn't find one. I
guess I will have to write a micro guide to these. 8)
