I had a basic copy function working, but I extended it to handle sub directories when passed ancestors and now receive an error.
def copy_to(dest, src)
files = FileList.new()
EXT_ALLOWED.each {|ext| files.include "#{src}/**/*.#{ext}"}
files.each do |file|
dir = File.dirname(file)
filename = File.basename(file)
path = dir.match(/shared\/(.*)/)
if dest == path[1] + '/'
bin = dest
else
bin = File.join(dest, path[1] + '/')
end
puts "copying #{filename} to #{bin}"
FileUtils.mkdir_p(bin)
FileUtils.cp src, bin
end
end
Here is how I am calling the function:
task :ui_gateway do
copy_to 'static/', 'c:/xampp/htdocs/home/shared/css'
copy_to 'static/', 'c:/xampp/htdocs/home/shared/fonts'
copy_to 'static/', 'c:/xampp/htdocs/home/shared/images'
copy_to 'static/', 'c:/xampp/htdocs/home/shared/lib'
copy_to 'static/', 'c:/xampp/htdocs/home/shared/scripts'
copy_to 'ui/', 'c:/xampp/htdocs/home/shared/ui'
end
The complete --trace:
C:\xampp\htdocs\home\app\gateway>rake ui_gateway --trace
(in C:/xampp/htdocs/home/app/gateway)
** Invoke ui_gateway (first_time)

The goal is to have a directory created in the destination directory which matches the directory(s) in the source. If the destination is static and the source is c:/xampp/htdocs/home/shared/css the resulting destination should be static/css/. Then the files from the shared directories would be copied to the destination. If the source has sub-directories they would need to be created as well and the dir.match() function seems to be getting the information required.
EDIT Added the following line if the if condition to make the appropriate directories and subs -
FileUtils.mkdir_p(bin)
This does create the appropriate directories and subs if I comment out the line which is suppose to perform the copy.
The file utilities in Ruby / Rake require that you are very specific about files in order to operate on them. In the original code src only refers to the path (2nd argument) sent to the copy_to function. The file names, as part of those paths, is not retrieved until the files.each loop:
files.each do |file|
At this point file contains the full path to the file as well as the file name. This is what must be the first argument in the copy function:
FileUtils.cp file, bin
PRIOR to attempting to copy any files all of the directories must be in place or you will get a different error:
copying c:/xampp/htdocs/home/shared/css/controls.css to static/css/
rake aborted!
Invalid argument - static/css/
Creating the new directories is done by adding the following line to the copy_to function just after the if condition:
FileUtils.mkdir_p(bin)
This creates the directory if it does not exist, which then allows the file to be copied into it.
Suggestion for improvement - It seems inefficient to try the mkdir_p on every file, rewrite this such that the directories are checked and then created if need be. (The additional overhead might not be worth an extra check, worth exploring.)
