fizzy

• a fizzy program consists of lines containing a sequence of one or more comma separated natural numbers followed by a colon, followed by a string.
• the final line in a fizzy program is two comma separated integers representing an inclusive range to loop over.
• when executed, a fizzy program shall print out the numbers in that range in increasing order
• except for values which are congruent to 0 modulo a number in each rule. these values will instead print the string associated with that rule
• only one number for each rule must match.
• multiple numbers for the same rule shall only print the string once
• multiple rules matching shall print each string in order from the lowest matching number to the highest
• a backwards range like 10,1 is allowed and indicates that iteration should be done in decreasing order
• a blank program is shorthand for the canonical fizzbuzz:

3:fizz
5:buzz
1,100

• a program consisting of just the range R is shorthand for:

3:fizz
5:buzz
R

• a range with just one number is assumed to start from 1
• rules producing the same string are allowed
• overlapping rules (rules with the same modulus) are allowed, they shall be printed in the order that they occure in the source code
• any line starting with # is a comment

Examples

• program:

2,4:hello
3:world
13

output:

1
hello
world
hello
5
helloworld
7
hello
world
hello
11
helloworld
13

• program:

1:_
2:.
3:,
6,0

output:

_.,
_
_.
_,
_.
_
_.,

• program:

1:🙃
2:🙃
4

output:

🙃
🙃🙃
🙃
🙃🙃

• program:

3,4:over
2,3:lap
2,6

output:

lap
overlap
lapover
5
lapover

Interpreter

The Python interpreter depends on textX which should run on Python 2.7+ or 3.3+ and is available through pip: $ pip install textX

The terrible test framework I threw together requires Python 3.5+ but the tester itself is there for my own convenience and is unnecessary to actually run Fizzy programs.
