LOLPython!

WHATZ LOLPython?

Example code to generate all Fibonacci numbers less than a given value of N. Max value is 100 if N is not given on the command line. Idea derives from original lolcode implementation by Kieran O'Niell.

IN MAI datetime GIMME date LIKE DATE

SO IM LIKE FIBBING WIT N OK?
    LOL ITERATE FIBONACCI TERMS LESS THAN N /LOL
    SO GOOD N BIG LIKE EASTERBUNNY
    BTW, FIBONACCI LIKE BUNNIES! LOL
    U BORROW CHEEZBURGER
    U BORROW CHEEZBURGER
    I CAN HAZ CHEEZBURGER
    HE CAN HAZ CHEEZBURGER
    WHILE I CUTE?
	I AND HE CAN HAZ HE AND I ALONG WITH HE
	IZ HE BIG LIKE N?
	    KTHXBYE
	U BORROW HE

IZ __name__ KINDA LIKE "__main__"?
    COMPLAIN "NOW IZ" AND DATE OWN today THING
    IZ BIGNESS ARGZ OK KINDA LIKE 1?
	N CAN HAS 100
    NOPE?
	N CAN HAS NUMBR ARGZ LOOK AT 1!!
    GIMME EACH I IN UR FIBBING WIT N OK?
	VISIBLE I

and in action (you must first install the most excellent PLY package):

% python lolpython.py fib.lol 60
NOW IZ 2007-06-01
1
1
2
3
5
8
13
21
34
55

It works by coverting the LOLPython code into Python. The converted Fibonacci in Python is:

# LOLPython to Python converter version 1.0
# Written by Andrew Dalke, who should have been working on better things.

# sys is used for COMPLAIN and ARGZ
import sys as _lol_sys

from datetime import date as DATE 

def FIBBING ( N ) :
    'ITERATE FIBONACCI TERMS LESS THAN N' 
    assert N >= 0 
    # BTW, FIBONACCI LIKE BUNNIES! LOL
    yield 1 
    yield 1 
    I = 1 
    HE = 1 
    while 1:
	I , HE = HE , I + HE 
	if HE >= N :
	    break 
	yield HE 

if __name__ == '__main__' :
    print >>_lol_sys.stderr, 'NOW IZ' , DATE . today ()
    if len(_lol_sys.argv) == 1 :
	N = 100 
    else :
	N = int(_lol_sys.argv[ 1 ]) 
    for I in FIBBING ( N ) :
	print I 

# The end.

Using LOLPython on the command line

Run a program from stdin

% echo "VISIBLE 'HAI WORLD!'" | python lolpython.py
HAI WORLD!
%

Translate a program from stdin into Python on stdout

% echo "COMPLAIN 'HAI WORLD!'" | python lolpython.py --convert
# LOLPython to Python converter version 1.0
# Written by Andrew Dalke, who should have been working on better things.


# sys is used for COMPLAIN and ARGZ
import sys as _lol_sys

print >>_lol_sys.stderr, 'HAI WORLD!' 

# The end.

Specify the LOLPython program filename on the command line

% cat count_letters.lol
LETTERZ CAN HAS INVISIBLE BUCKET
F CAN HAS open WIT "count_letters.lol"!
S CAN HAS F OWN read THING
GIMME EACH C IN THE S?
    N CAN HAS LETTERZ OWN get WIT C AND 0! ALONG WITH CHEEZBURGER
    LETTERZ LET THE C OK CAN HAS N
GIMME EACH C IN THE sorted WIT LETTERZ OK?
    VISIBLE repr WIT C! AND LETTERZ LOOK AT C!
% python lolpython.py count_letters.lol | head
'\n' 8
' ' 67
'!' 4
'"' 2
'.' 1
'0' 1
'?' 2
'A' 16
'B' 4
'C' 15

Translate one or more LOLPython program files into Python files

% python lolpython.py --convert count_letters.lol
% cat count_letters.py 
# LOLPython to Python converter version 1.0
# Written by Andrew Dalke, who should have been working on better things.


# sys is used for COMPLAIN and ARGZ
import sys as _lol_sys

LETTERZ = {}
F = open ( 'count_letters.lol' ) 
S = F . read ()
for C in S :
    N = LETTERZ . get ( C , 0 ) + 1 
    LETTERZ [ C ] = N 
for C in sorted ( LETTERZ ) :
    print repr ( C ) , LETTERZ [ C ] 

# The end.
