Now new version is being developed in 'next' directory. It will replace current C++ implementation.
Dachs is a general-purpose programming language designed to be enjoyable, statically-typed and dog-friendly. Dachs is intended to be used for efficient applications and tools development, not for system programming.
Goals
- Light to write (inspired by Ruby)
- Strongly and statically typed
- Native code efficiency
- OOP
- Immutability-aware
- Familiar with functional features
- Dog-friendly
# If 'var' is specified, the argument is copied and passed by value
# then mutable. Otherwise, the argument is passed by reference then
# immutable. Variable definition has the same rule as this.
# Type of arguments and returned value are deduced automatically.
# If you want to specify the type of argument, you can use ':'.
# e.g.
# func step_to(var first : float, last : float, block) : ()
func step_to(var first, last, block)
for first <= last
block(first)
first += 1
end
end
# UFCS is implemented.
# '1.step_to n' is equivalent to 'step_to(1, n)'
# Dachs has a block inspired from Ruby.
# do-end block is passed to the last argument of callee as lambda object.
# Here, 'block' variable is captured into do-end block.
func fizzbuzz(n, block)
1.step_to n do |i|
case
when i % 15 == 0
block("fizzbuzz")
when i % 3 == 0
block("fizz")
when i % 5 == 0
block("buzz")
else
block(i)
end
end
end
func main
fizzbuzz 100 do |i|
println(i)
end
end
# Array and tuple are available as container.
# (dictionary will come.)
