No, some clojure.core.* namespaces are contribs (and need a
project.clj dependency), some are built-in. Per my original email:

Everything listed in the left hand column is a contrib that you need
to pull in (as a dependency) in your project.clj, including:

core.cache
core.incubator
core.match
core.memoize
core.unify

(and core.logic which is, for some reason, missing from that list)

Anything listed in the left hand column here is built-in (also listed
under Table of Contents on the right), no dependency needed (other
than Clojure itself), you just need to :require it in your namespace.

Finding clojure.core.protocols is a little harder, since it's a
sub-namespace of clojure.core so you'll find it here:

http://clojure.github.com/clojure/clojure.core-api.html

Specifically:

http://clojure.github.com/clojure/clojure.core-api.html#clojure.core.protocols

You might find the Clojure Atlas helpful for navigating the built-in
Clojure namespaces and functions:

http://www.clojureatlas.com/

It's a bit of a sprawling universe of namespaces and can be a bit
daunting when you first start working in Clojure but you soon get used
to the layout (honest!).

Hope that helps?

Oooh, one more bullet point for contrib libs:

  * they don't have a project.clj file. They use a  pom.xml file 
instead!

Thought I'd add that, being that it's so close to Halloween and all. ;)

Most of these are, of course, managed by Leiningen and so *do* have a 
project.clj file.

Hi Larry,

Note that, concerning libraries, there's three separate but often similar 
names to be aware of:

  * the lib's artifact-id (you'll find it at the top of the lib's very own 
project.clj).
  * the lib's github project name (if it's hosted there)
  * the namespace(s) that the lib provides (specified in the lib's source 
file(s) in the `ns` macro)

Threre's also the lib's group-id, which --- if different from the 
artifact-id --- is also noted at the top of a lib's project.clj file.

You use a lib's group-id and artifact-id in your own project.clj when you 
specify dependencies (group-id is left out when it's the same as the 
artifact-id, which is common for many 3rd-party Clojure libs).

You use a lib's namespace name(s) in your own source's `ns` macro to use 
that lib in your code.

Some notes about contrib libs:

  * all have a group-id of "org.clojure", and
  * all have github project names like "foo.bar" (ex. 
"math.combinatorics"), under https://github.com/clojure
  * all have namespace names like "clojure.foo.bar" (ex. 
"clojure.math.combinatorics").
  * they're hosted at maven central, not at clojars
  * you can find them all listed at 
http://dev.clojure.org/display/doc/Clojure+Contrib

Some notes about 3rd-party Clojure libs:

  * many have a group-id the same as their artifact-id
  * most are hosted at github, and usually the github project name is the 
same as the artifact-id
  * most are available at Clojars via leiningen
  * many have a namespace like "my-proj.core"

(Anyone: If there's any errors there, please let me know!)

Re: what is the modern equivalent of clojure.contrib.java-utils/file?

2012-10-25 Thread Ben Smith-Mannschott 
Anything that starts with "clojure." is part of (some version of) clojure.

For Clojure 1.4, that's everything listed in "Table of Contents" on
the right side of the web page you'll find here:

http://clojure.github.com/clojure/

clojure.core
clojure.data
clojure.inspector
clojure.java.browse
clojure.java.io
clojure.java.javadoc
clojure.java.shell
clojure.main
clojure.pprint
clojure.reflect
clojure.repl
clojure.set
clojure.stacktrace
clojure.string
clojure.template
clojure.test
clojure.walk
clojure.xml
clojure.zip

That'll all be available without needing to add dependencies to your
project.clj. You'll just need to :require it as usual in your ns form.

Okay, if I look here:


http://clojure.github.com 


Can I assume that anything that starts with "clojure.core" is not a 
dependency? And everything else is? 


So this would be listed as a dependency if I use it:


clojure.test.junit



but I would not have to list this as a dependency:

clojure.core.protocols

If it's listed separated there, it's a contrib you need to pull in
explicitly. Otherwise it's part of Clojure itself.

OK I'll grant you this...Documentation is not the strong part of 
Clojure. There have been/still are efforts to improve on this but 
generally any newcomer to the language struggles at first...A general 
rule of thumb is that if something starts with clojure.something.. 
chances are it is part of Clojure itself (there are exception though e.g 
clojure.java.jdbc)...


hope that helps :-)

are you aot compiling? If yes delete all the calss files and 
re-compile...also there is no reason to require it unless you alias it 
to something... a common one would be (:require [clojure.java.io :as

name most of the times
