Mailman 3 Pythonect 0.1.0 Release - Python-ideas

April 1, 2012

      Hi All,

I'm pleased to announce the first beta release of Pythonect interpreter.

Pythonect is a new, experimental, general-purpose dataflow programming
language based on Python.

It aims to combine the intuitive feel of shell scripting (and all of its
perks like implicit parallelism) with the flexibility and agility of
Python.

Pythonect interpreter (and reference implementation) is written in Python,
and is available under the BSD license.

Here's a quick tour of Pythonect:

The canonical "Hello, world" example program in Pythonect:
...
...
...
"Hello World" -> print
<MainProcess:Thread-1> : Hello World
Hello World
'->' and '|' are both Pythonect operators.

The pipe operator (i.e. '|') passes one item at a item, while the other
operator passes all items at once.

Python statements and other None-returning function are acting as a
pass-through:
...
...
...
"Hello World" -> print -> print
<MainProcess:Thread-2> : Hello World
<MainProcess:Thread-2> : Hello World
Hello World
...
...
...
1 -> import math -> math.log
0.0
Parallelization in Pythonect:
...
...
...
"Hello World" -> [ print , print ]
<MainProcess:Thread-4> : Hello World
<MainProcess:Thread-5> : Hello World
['Hello World', 'Hello World']
...
...
...
range(0,3) -> import math -> math.sqrt
[0.0, 1.0, 1.4142135623730951]
In the future, I am planning on adding support for multi-processing, and
even distributed computing.

The '_' identifier allow access to current item:
...
...
...
"Hello World" -> [ print , print ] -> _ + " and Python"
<MainProcess:Thread-7> : Hello World
<MainProcess:Thread-8> : Hello World
['Hello World and Python', 'Hello World and Python']
...
...
...
[ 1 , 2 ] -> _**_
[1, 4]
True/False return values as filters:
...
...
...
"Hello World" -> _ == "Hello World" -> print
<MainProcess:Thread-9> : Hello World
...
...
...
"Hello World" -> _ == "Hello World1" -> print
False
...
...
...
range(1,10) -> _ % 2 == 0
[2, 4, 6, 8]
Last but not least, I have also added extra syntax for making remote
procedure call easy:
...
...
1 -> inc@xmlrpc://localhost:8000 -> print
<MainProcess:Thread-2> : 2
2
...
