Sila

The simple transpiler infrastructure for every platform. But, now is support JavaScript, Ruby and Python. Other platforms are coming soon!

Example

use sila_transpiler_infrastructure::{
    transpile_javascript, transpile_python, transpile_ruby, Block, Expr, Instruction, Library,
    Operator, Type,
};

fn main() {
    let program: Block = vec![

Output

JavaScript:
// Sila transpiled this code
function show(count) {
    return (`counter value is ` + String(count))
};
let count = 0;
try {
    let limit = parseInt(prompt(`limit: `))
} catch {
    let limit = 10
};
while (count < limit) {
    count = (count + 1);
    if (count % 2 == 0) {
        continue
    };
    console.log(show(count))
}

Ruby:
# Sila transpiled this code
def input(prompt)
    print prompt
    return gets.chomp
end

def show(count)
    return ("counter value is " + String(count))
end
count = 0
begin
    limit = Integer(input("limit: "))
rescue
    limit = 10
end
while (count < limit) do
    count = (count + 1)
    if (count % 2 == 0)
        next
    end
    puts show(count)
end

Python:
# Sila transpiled this code
def show(count):
    return ('counter value is ' + str(count))
count = 0
try:
    limit = int(input('limit: '))
except:
    limit = 10
while (count < limit):
    count = (count + 1)
    if (count % 2 == 0):
        continue
    print(show(count))
