Comment: Removed all the (outdated) clojure.contrib mentions per Stuart Sierra.

...

As a first stop, please consider the libraries in Clojure Contrib, a repository for libraries contributed to the Clojure project and candidates for inclusion in core.

Note: The mentions of clojure.contrib below are out of date and should be removed since the Clojure Contrib page linked above supersedes all "old" contrib information.

Category: OS integration

  • clojure.contrib.command-line

    Parses command-line options according to your programs specifications.

    Provide --help output automatically.
  • clojure.contrib.shell-out

    Launch external programs and collect their output.
  • clojure.contrib.mmap

    Thin wrapper around Java's memory-map support. Provides versions of

    'slurp' and 'load-file' that use mmap internally.

Category: meta-clojure

3rd party dep: http://www.graphviz.org/

  • clojure.contrib.repl-utils

    Provides tools for examining Clojure source code and Java classes at

    the REPL.

Category: xml

  • clojure.contrib.lazy-xml

    XML parser/emitter using an in-memory format that's compatible with

    clojure.xml. The primary differences are that it produces lazy seqs

    of content nodes (instead of vectors), and that it can use a pull

    parser API internally. Works well with zip-filter.xml

Optional 3rd party dep: http://www.extreme.indiana.edu/xgws/xsoap/xpp/

  • clojure.contrib.zip-filter
  • clojure.contrib.zip-filter.xml

    Produces lazy sequences of nodes from an XML document that match the

    given chain of filter expressions. Similar in feel to XPath, but

    using Clojure syntax and easily extensible with custom filter

    expressions.

pprint

http://github.com/clojure/clojure-contrib/

Author: Tom Faulhaber

Tags: pretty printing, formatted output, Common Lisp compatibility

License: EPL

Dependencies: none (outside of contrib)

  1. A flexible, customizable pretty printer for displaying clojure code and data (and potentially other structured data as well).
  2. A fully functional implementation of Common Lisp's crazy powerful format function. cl-format provides a way of producing formatted

    output in the "lisp style" in which the format string itself can perform destructuring on the input arguments rather than having

    complex iterations and conditionals in your code to do output.
