Hi J, asshb, et al,
Thanks for your replies. I think I have the question of applying a style to
a class down, now.  I might tackle the new widget thing or not, but it's
good to know that I can at least display the characters I need in the
listbox as is, even if they're a bit small for my liking.

May the shoes be with you,
Ros

I'm just now starting to play with Shoes (and Ruby for that matter … I've 
been an AppleScript person for a long time)… 

I do have a basic question though (maybe this is more Ruby related than 
Shoes), but here goes.

In this basic script I came up with to list the files, I want to list full
paths. How do I do that? 

Shoes.app :title =>'Add Navtitle Field', :width => 300 do
  stack do
    para "Choose the directory to list files"
    button("Choose") do
	folder = ask_open_folder
	clear()
	Dir.entries(folder).each {|indfile| para "files are: " + indfile + "\n"} 
	end
  end
end


I would think I should be able to use the Files.dirname but when I tried, 
it failed and I'm not so sure I can. Maybe it's all a matter of 
misunderstanding how File.dirname is used.

hi Wayne,

  welcome to Shoes!

  try this:

       Dir.entries(folder).each {|indfile| para "files are: " +
File.expand_path(indfile) + "\n"}

  hth,

Let's try this again, making sure plain text is selected. Sorry folks! 

I suspect it's just me being the idiot, and trying to think this script 
out the way I would have done it in AppleScript, but If I did something 
like this in AppleScript: 

set SourceFolder to choose folder
tell application "Finder"
	set FileNames to name of every file of SourceFolder
end tell

What I guess I'm trying to figure out is how to get shoes to do this same 
behavior. That is all me to pick a directory, so that later I can go 
through that directory and parse various files. Looking at Eric's example,
he provided the path, but what I'm missing I think is how to get that path
from shoes pick a directory dialog.

Also, did the Mac OS X 10.7 version of Shoes ever get released?

Wayne, 
  
  Try this little Shoes/Ruby snippet that pops up a dialog box for the
folder name and displays the file names and folder names within.

Shoes.app do
  dirString = ask_open_folder
  title dirString+":\n"
  fileNames = []
  Dir.foreach(dirString) do |nm| 
    fileNames << nm
  end
  fileNames.each do |foo| 
    para dirString+"/"+foo+"\n"
  end
end

For an Applescripter there are many rubyism's in that snippet that may
confuse you as when mixed into Shoes. In Ruby, there are many ways to
get a file list and I know my example is not the best way, but it does
put up a dialog for a folder, it runs through folder contents and
creates an array of the filenames inside (beware -- sub-folders are
filenames too) and it prints out the full path to the file (or
subdirectory). Dot (.) and Dot-dot (..) are file names and directories.

Thanks Cecil. This does do what I was wanting to do.

Hi all, it's  me again. ;) 

I'm wondering if this is a Shoes thing, or a Ruby thing, but 
File.expand_path isn't returning the right path. Initially I didn't notice
this since I tested this on a directory that was on the same volume as the
test Shoes script. However, when I tried this  on a directory that resided
on another volume, my path stayed the same as the previous one. In all 
cases it looks like it's using the path to where the script resides, not 
where the files are located.

What am I missing? shouldn't the File methods point to the files and not 
where the Shoes script resides? 

Thanks,
Wayne

Wayne, 

It's a ruby thing ;)

File.expand_path is kind of dumb. It doesn't look for a real path, it just
tells you what the full path to the filename you specify *would be*. With 
one argument, it give the full path assuming the file is in the current 
directory. If you want the full path to a different directory, just pass 
that directory as the second argument. Like this:


huckle:code eric$ irb
rbx-head :001 > f = "file.txt"
 => "file.txt" 
rbx-head :002 > File.expand_path f
 => "/Users/eric/code/file.txt" 
rbx-head :003 > File.expand_path f, "/Volumes/some/other/volume"
 => "/Volumes/some/other/volume/file.txt" 
rbx-head :004 > 


Hope that helps!

Eric

hi Wayne,

  as far as i understand it, File.expand_path always returns the path that
the script is located in - it can be used for locating other files or
directories relative to where the script is.

  if you want to recursively search another directory and extract the paths
of all the files and directories in it, check out the Find module...

Thanks! That worked perfectly. : )
