<h2>Overview</h2>
<pre id="namespace-docstr">A Pretty Printer for Clojure
clojure.pprint implements a flexible system for printing structured data
in a pleasing, easy-to-understand format. Basic use of the pretty printer is
simple, just call pprint instead of println. More advanced users can use
the building blocks provided to create custom output formats.
Out of the box, pprint supports a simple structured format for basic data
and a specialized format for Clojure source code. More advanced formats,
including formats that don't look like Clojure data at all like XML and
JSON, can be rendered by creating custom dispatch functions.
In addition to the pprint function, this module contains cl-format, a text
formatting function which is fully compatible with the format function in
Common Lisp. Because pretty printing directives are directly integrated with
cl-format, it supports very concise custom dispatch. It also provides
a more powerful alternative to Clojure's standard format function.
See documentation for pprint and cl-format for more information or
complete documentation on the the clojure web site on github.</pre>

<span id="var-type">function</span><br />
<pre id="var-usage">Usage: (cl-format writer format-in & args)
</pre>
<pre id="var-docstr">An implementation of a Common Lisp compatible format function. cl-format formats its
arguments to an output stream or string based on the format control string given. It
supports sophisticated formatting of structured data.
Writer is an instance of java.io.Writer, true to output to *out* or nil to output
to a string, format-in is the format control string and the remaining arguments
are the data to be formatted.
The format control string is a string to be output with embedded 'format directives'
describing how to format the various arguments passed in.
If writer is nil, cl-format returns the formatted result string. Otherwise, cl-format
returns nil.
For example:
(let [results [46 38 22]]
(cl-format true "There ~[are~;is~:;are~]~:* ~d result~:p: ~{~d~^, ~}~%"
(count results) results))
Prints to *out*:
There are 3 results: 46, 38, 22
Detailed documentation on format control strings is available in the "Common Lisp the
Language, 2nd edition", Chapter 22 (available online at:
<a href="http://www.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/html/cltl/clm/node200.html#SECTION002633000000000000000">http://www.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/html/cltl/clm/node200.html#SECTION002633000000000000000</a>)

<pre id="var-usage">Usage: (get-pretty-writer writer)
</pre>
<pre id="var-docstr">Returns the java.io.Writer passed in wrapped in a pretty writer proxy, unless it's
already a pretty writer. Generally, it is unneccesary to call this function, since pprint,
write, and cl-format all call it if they need to. However if you want the state to be
preserved across calls, you will want to wrap them with this.
For example, when you want to generate column-aware output with multiple calls to cl-format,
do it like in this example:
(defn print-table [aseq column-width]
(binding [*out* (get-pretty-writer *out*)]
(doseq [row aseq]
(doseq [col row]
(cl-format true "~4D~7,vT" col column-width))
(prn))))
Now when you run:
user> (print-table (map #(vector % (* % %) (* % % %)) (range 1 11)) 8)
It prints a table of squares and cubes for the numbers from 1 to 10:
1 1 1
2 4 8
3 9 27
4 16 64
5 25 125
6 36 216
7 49 343
8 64 512
9 81 729
