Hi,
I'd greatly appreciate feedback on the following code.
def create_files
names_array = self.read_names #another method in my class
while names_array.length != 0
name = names_array.pop
File.open( name, "w" ) { |f| f.puts "File is no longer empty" }
end
x.create_files
Which results in:
C:/Scripts/Ruby/file_gen.rb:34:in `initialize': Invalid argument - echo (Errno
::EINVAL)
from C:/Scripts/Ruby/file_gen.rb:34:in `open'
from C:/Scripts/Ruby/file_gen.rb:34:in `create_files'
from C:/Scripts/Ruby/file_gen.rb:42
The array contains the strings 'alpha' through 'foxtrot' and before
producing the error above the file 'foxtrot' is created. So the logic
works once before failing.
When I pull this code out of the class definition it works perfectly
and creates
a file for every name in the array. What noob mistakes am I making?
Thanks,
S.
