daot 0.7.4

the dao to programming, lisp meets prolog in python.

This is Dao 0.7.4
============================

What would happen when lisp meets prolog in python?

Dinpy arises!

Dao is the new generation programming system implemented by a functional logic solver,
unifying code with data, grammar with program, logic with functional, compiling with running.

------------------
How to use Dao?
------------------

!!! This readme in ReStructureText format does not works in pypi.
What's wrong with this(see dao\readme and dao\setup.py)?
I don't find the reason even after reading pypi tutorial, google and trying a lot ways.
If any one know please show me how to fix it ([e-mail]) and thanks a lot.

See the "get start" in the <http://code.google.com/p/daot/w/list> to get started with dao and dinpy.
See <http://packages.python.org/daot> for document about dao and dinpy.
See the tests, and you'll get some information about the interface and use cases.

Have a look at running Dinpy in interactive mode in the python shell below::

>>> from dao.dinpy import *

>>> i<<0
0
>>> quote(i/i+i*1)
i/i+i*1
>>> let(i<<1).do[prin(i)]
1
>>> loop(3)[ prin(i), ++i ]
0 1 2
>>> loop [ prin(i), --i]. until(i==0)
3 2 1
>>> when(i!=0).loop[ prin(i), --i]
3 2 1
>>> loop [ prin(i), ++i, iff(i==3) .do[exit] ]
0 1 2
>>> each(i)[0:3].loop[prin(i)]
0 1 2
>>> i << 0
0
>>> loop[ println('outer loop'), loop[ prin('inner loop: '), println(i), ++i, iff(i==3).do[ exit*2 >> 'exit from inner' ] ] ]
outer loop
inner loop: 0
inner loop: 1
inner loop: 2
'exit from inner'
>>> fun.f1(x) == [x+x]
f1
>>> f1(2)
4
>>> letr (f2 << fun(x)[ iff(x<1).do[x].els[f2(x-1)]]) .do [f2(3)]
0
