File.new : having problems in windows

ruby-talk
1

Hi all,

I’m a relatively new user to ruby. I was trying to use the File.new
and was using a directory path as well. It seems like ruby wants to
replace the \ (backslash) for the directory paths with a double
backslash \.

How can I get around this or fix this problem?

··· 
         directory = "\\blah\\test.txt"
         printf ("This is string stores %s \n\n",directory)
         d = File.new(directory,"w+")

Output:

This is string stores \blah\test.txt

parser.rb:20:in initialize': No such file or directory - "\\blah\\test.txt" NOENT) from parser.rb:20:innew’
from parser.rb:20

It looks like the directory name is stored correctly but the file.new
function tries to add an extra \ into the directory names.

Thanks,

You should either use single quotes to store filenames (so the
backslashes aren’t interpreted by ruby), or use forward slashes as your
path delimiter (if I remmeber correctly, that also works correctly in
Windows).

So, instead of

directory = “\blah\test.txt”

Use single quotes:

directory = ‘\blah\test.txt’

or forward slashes

directory ‘/blah/test.txt’

         directory = "\\blah\\test.txt"
         printf ("This is string stores %s \n\n",directory)
         d = File.new(directory,"w+")

Output:

This is string stores \blah\test.txt

parser.rb:20:in initialize': No such file or directory - "\\blah\\test.txt" NOENT) from parser.rb:20:in new’
from parser.rb:20

It looks like the directory name is stored correctly but the file.new
function tries to add an extra \ into the directory names.

It’s not adding an extra backslash; the error handing is calling inspect
on the string, which escapes it. For example:

irb(main):003:0> puts “\asdf”.inspect, ‘\asdf’.inspect
“\asdf”
“\asdf”

The problem you’re having is exactly what the error message says: there
is no file or directory called ‘\blah\test.txt’. I have no experience
running ruby under Windows, but my best guess would be to try either
‘\c\blah\test.txt’ or ‘/c/blah/test.txt’.
