Rubi is a high-level, high-performance script programming language, with syntax that is familiar to users of Ruby. Rubi is implemented via just-in-time compilation.
Anyone who is familiar to Ruby programming language should learn Rubi quickly.
Sample programs can be found in the directory progs.
- Syntax
# Statement => write in the function.
# output the string and number
# puts is output and \n
# output is output only.
puts "Hello world!!" # => Hello world!!\n
puts "number = ", 65536 # => number = 65536\n
output "not new line" # => not new line
# declaration is not required
# support only integer
i = 10
i = i + 43
i = i % 5
i = i - 32
sum = i * (12 / 5)
12 / 5 # => 2
# loop and if
for i = 1, i < 100, i = i + 1
if i % 15 == 0
puts "fizzbuzz"
elsif i % 5 == 0
puts "buzz"
elsif i % 3 == 0
puts "fizz"
else
puts i
end
end
# create function
# return is not support...
def sum(n)
sm = 0
for i = 1, i <= n, i = i + 1
sm = sm + i
end
sm
end- Implement Fibonacci in Rubi:
def fib(n)
if n < 2
1
else
fib(n - 1) + fib(n - 2)
end
end
puts fib(39)Rubi is freely redistributable under the two-clause BSD License.
