Good morning,
Re: Today's Topic 1 - see below.
My apology for not including the error message.
The following is what I did:
I downloaded the source code and did the following [from the O'Reilly
book]:
1. download was done on a Mac.
2. I saved the file to helloWorld.hs
3. I went to my terminal screen and executed:
runhaskell helloworld.hs
4. on the terminal the following appeared:
hell yeah
5. so far, so good
6. I went to my browser and entered the url:
http://localhost:3000
7. I was expecting to see the following on my browser:
<!DOCTYPE html>
<html><head><title></head><body>hell yeah</body></html>
8. Unfortunately, I get the following message:
"Safari can't connect to Server
Safari can't open page "http://localhost:3000"; because
Safari can't connect to server "localhost"
Good day,
Patrick

Hi again,
I took the liberty to change the topic name to something clearer.
Which code are you following? I don't have the copy of a book with me
but it's available online. Is the code from
http://www.yesodweb.com/book/basics what you're trying?

Is there a version of copyFile that will create the directory structure if it
does not exist yet?
Thanks,

No, I don't think so, I think you'll have to write one by combining
System.Directory.createDirectoryIfMissing with
System.Directory.copyFile.
