Bosatsu (菩薩) is the transliteration in Japanese of the sanskrit bodhisattva. A bodhisattva is someone who can reach enlightenment but decides not to, to help others achieve that goal. -- Wikipedia
Bosatsu is a simple, non-turing complete language designed for configuration, queries and scripting. It borrows from Python, Haskell, Dhall and Rust.
Please see the documentation site and the Getting started guide or try basic expressions using this in-browser Bosatsu compiler.
Here is a working Bosatsu program to solve the first Project Euler problem:
package Euler/One
# see:
# https://projecteuler.net/problem=1
# Find the sum of all the multiples of 3 or 5 below 1000.
operator == = eq_Int
operator % = mod_Int
def operator ||(x, y):
True if x else y
def keep(i):
(i % 3 == 0) || (i % 5 == 0)
def sum(as): as.foldl_List(0, add)
# here is the python version:
# >>> sum(i for i in xrange(1000) if keep_fn(i))
# 233168
#
# bosatsu version here
computed = sum([i for i in range(1000) if keep(i)])
test = Assertion(computed == 233168, "expected 233168")
