I'm not sure who to have an array format correctly when written to a text file.
Doing something like myarray = ['five','four','three','two','one']
works almost correctly but
myarray = ['.././*.docs'] seems to write them out without linebreaks.
So while I can figure out how to print them nicely using some iterator
to the screen
Using,
File.open filename, 'w' do |doc|
doc.write myarray
end
I can't seem to figure out a way to format the strings correctly.

I'm not sure who to have an array format correctly when written to a text file.
What does "correctly" mean?
Doing something like myarray = ['five','four','three','two','one']
works almost correctly but
myarray = ['.././*.docs'] seems to write them out without linebreaks.
This is not a print statement. What did you do to actually print it?
So while I can figure out how to print them nicely using some iterator
to the screen
Using,
File.open filename, 'w' do |doc|
doc.write myarray
end
I can't seem to figure out a way to format the strings correctly.
Try this:
doc.write myarray.join ", "
Depends on what you mean by "proper output".
Kind regards

I must have not explained myself well.
Right now my file looks like this:
c:/dir1/doc1.docc;/dir1/doc3.docc:/dir1/doc4.docc:/dir1/doc5.doc
..........i.e. no line breaks
I want it took look like this:
c:/dir1/doc1.doc
c;/dir1/doc3.doc
c:/dir1/doc4.doc
c:/dir1/doc5.doc
..........

Try using 'doc.puts' instead of 'doc.write'. 'puts' will automatically add line breaks, whereas 'write' will not.

Thank you that was a huge improvement, still battling a few more format issues:
when I open the file:
It has the 3 hypens as the first line and a hyphen before every file
name. Can't I get rid of those ?

I'd think there has to be a way.

Thank you that was a huge improvement, still battling a few more format issues:
when I open the file:
It has the 3 hypens as the first line and a hyphen before every file
name. Can't I get rid of those ?---
- c:/dir1/doc1.doc
- c:/dir1/doc2.doc
- c:/dir1/doc3.doc
- c:/dir1/doc4.doc
- c:/dir1/doc5.doc
- c:/dir1/doc6.doc
How are you building the array? What you are seeing as output must be what's in the array, unless you are adding those hyphens at some point. Maybe do a
p myarray
to see exactly what is in the array.
Of course, you could just do some string parsing and remove the hyphens.

You are comparing a string to an array. File.read returns a string. Try something like:
readlist = File.readlines(filename).map { |line| line.chomp}
File.readlines will return an array with an element for each line. But they will then have the end-of-line character attached (added when we wrote the file), so we have to remove those with chomp.
