============
A Programming Language just for writing [Fizz Buzz](https://en.wikipedia.org/wiki/Fizz_buzz) program. :)
```
for n from 1 to 100
puts n % 3 == 0 ? (n % 5 == 0 ? 'FizzBuzz' : 'Fizz') : (n % 5 == 0 ? 'Buzz' : n)
```
Build and Run demo

```
PEG grammar
-----------
```peg
# Syntax Rules
EXPRESSION <- TERNARY
TERNARY <- CONDITION ('?' EXPRESSION ':' EXPRESSION)?
CONDITION <- MULTIPLICATIVE (ConditionOperator MULTIPLICATIVE)?
MULTIPLICATIVE <- CALL (MultiplicativeOperator CALL)*
CALL <- PRIMARY (EXPRESSION)?
PRIMARY <- FOR / Identifier / '(' EXPRESSION ')' / String / Number
FOR <- 'for' Identifier 'from' Number 'to' Number EXPRESSION
# Token Rules
ConditionOperator <- '=='
MultiplicativeOperator <- '%'
Identifier <- !Keyword < [a-zA-Z][a-zA-Z0-9_]* >
String <- "'" < ([^'] .)* > "'"
Number <- < [0-9]+ >
Keyword <- 'for' / 'from' / 'to'
%whitespace <- [ \t\r\n]*
