hi all,
What's the difference between these two snippets?
1.
(ns my-ns
(require [package.name.a]))
2.
(ns my-ns
(:require [package.name.a]))
They all works!But I wonder what's the differences between them.
thx!

By coincidence they are both equivalent and expand to exactly the same code.
The latter is preferred, and it's debatable if the former should even be
legal.
Thanks,
Ambrose

I believe one is a directive and the other is a function.:require doesn't need the values to be quoted (:require xyz)require needs values to be quoted so that they're not evaluated when passed as arguments (require 'xyz)I could be wrong though. 06.12.2013, 18:17, "BillZhang"
Hi Folks
firstly a big thank you for all the help so far. I posted the original
question because I've been looking at Midje which has the ability to stub
out a function but have the stub function return different data each time
it is called (it also counts the number of times the stubbed
Inside the ns form they are the same. Outside the ns form, only (require
'[a.b]) works (with quoting, as Kelker said).

Parenthesis call the thing they wrap as a function. You have getConnection
wrapped in a redundant set of parenthesis, so the return value of
getConnection is being called. It is not a function, but it is a
ConnectionCustom, so you get your error.
Some hints to make clojure code more readable:
To add some further clarification to the style hints suggested: many of us
read code in multiple languages, and using formatting that is idiomatic to
the language being used helps us keep the rules straight. f(a b) is an
algol family syntax, the lisp family has a direct equivalent of (f a b),

Penny Black allows you to declaratively create functions which send HTML
and text emails using mustache templates. It's inspired by ActionMailer.
You might find it useful if you have an application that sends email :)
Here's an example of defining
Glad it worked, if you have any further questions feel free to ask. I'm
using it extensively and it and Clojure seem to be a perfect match these
days, especially on very large datasets.

I use a default reader to do something like what you're asking for in my
'tagged' library. You could hack a similar default reader that restricted
itself just to your favorite namespaces. That way you don't have to
explicitly track all your defrecord classes.

Good day everyone,
I inadvertently passed a double to a timeout channel and discovered the
following behavior:

nil
user= (a/timeout 100.0)

I have a working prototype of bits, which are encoded from 32 flags and
decoded back to them. I've added a couple of helper methods such as
`set-bits-at` and `get-set-bits` and so on to facilitate it.
Although I recommend using enums for that (which is possible in majority of
cases).
I'll
@Thomas, let me know if you run into any problems. Since the project is
quite young, I'm very open to add a couple of features. Rob, Ulisses and
Cesar have done a very nice job providing some very nice ideas!

Instead of trying to do it that way, how about just a thin layer of macrology
around defrecord? Within the def-record-reader firm you have access to all the
info you need for each reader, without extensive code-walking etc
