Hi,
I got an example rakefile from the webpage
http://jasonseifer.com/2010/04/06/rake-tutorial
which displays "Published: April 6, 2010 at 4:25 AM"
Below are my results from testing that rakefile in a Command window on
WinXP-Pro/SP3 running Rails 2.3.5, where Rake complained "Don''t
know
how to build task ''default''". How do I get it to run as
I intend?
Thanks in Advance,
Richard

OK, I got took one of the first examples of the website I cited before,> >http://jasonseifer.com/2010/04/06/rake-tutorialand found that it didn''t work "in any directory" as advertised. I did three things: 1 Upgraded the example so that it would work "in any directory" (I suspect it would work in the root dir.) 2. Added command[echoing code 3. Remove spurious quotes from the argument of the echo command. Comments in the Rakefile below spell out all the details if you''re interested. Thanks for nudging me forward.

> maybe this is a Windows-specific issue?Good question. I copied the Tempfile to C:\ Ran my version, which added the working dir. to tmp.txt Ran fine. Ran original version -- same problem. So my speculation was wrong. Maybe that''s because Windows has no real root. There''s just the \ address in a partition. I''ve got about a half-dozen partitions, plus similar symbols for some devices It looks to me like the author does run on U*ix, because his next example is: [jason@brick:~/src]$ rake ready_for_the_day. There also a typo for this example: He claims the output from this command includes the line: Made 5 cups of coffee. Shakes are gone. In fact, it''s only 2 cups. His next example: [jason@brick:~/src]$ rake COFFEE_CUPS=5 make_coffee produces the 5 cup. I''m just amused be the problem the author faced in trying to produce a perfect tutorial. I know that feeling all too well. And I am truly grateful for the author publication of his tutorial. It''s leading me through the nuances of Rake. And thanks to you for helping me in my quest for a "black belt" in Rake-ism :-) Best wishes, Richard On Jul 11, 2:04 pm, Hassan Schroeder <hassan.schroe...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On Sun, Jul 11, 2010 at 9:51 AM, RichardOnRails > > <RichardDummyMailbox58...-gP6xRNRnnqSxhq/XJNNIW0EOCMrvLtNR@public.gmane.org> wrote: > > > I got took one of the first examples of the website I cited before, > >> >http://jasonseifer.com/2010/04/06/rake-tutorial > > and found that it didn''t work "in any directory" as advertised. > > It does indeed work "in any directory" for me, but that''s on OS X; > maybe this is a Windows-specific issue? > > ripple:~$ cd Downloads > ripple:~/Downloads$ cat Rakefile > directory "tmp" > > file "hello.tmp" => "tmp" do > sh "echo ''Hello'' >> ''tmp/hello.tmp''" > end > ripple:~/Downloads$ ls tmp > ls: tmp: No such file or directory > ripple:~/Downloads$ rake hello.tmp > (in /Users/hassan/Downloads) > mkdir -p tmp > echo ''Hello'' >> ''tmp/hello.tmp'' > ripple:~/Downloads$ ls tmp/hello.tmp > -rw-r--r-- 1 hassan staff 6 Jul 11 10:59 tmp/hello.tmp > ripple:~/Downloads$ cat tmp/hello.tmp > Hello > ripple:~/Downloads$ > > FWIW, > -- > Hassan Schroeder ------------------------ hassan.schroe...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org > twitter: @hassan-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
