README
# We need financial support to continue development. Please [become a sponsor](https://opencollective.com/cotowali).
## Concepts of Cotowali
- Outputs shell script that is fully compliant with POSIX standards.
- Simple syntax.
- Simple static type system.
- Syntax for shell specific feature like pipe and redirection.
## Example
```v
fn fib(n: int): int {
if n < 2 {
return n
}
return fib(n - 1) + fib(n - 2)
}
fn int |> twice() |> int {
var n = 0
read(&n)
return n * 2
}
assert(fib(6) == 8)
assert((fib(6) |> twice()) == 16)
fn ...int |> sum() |> int {
var v: int
var res = 0
while read(&v) {
res += v
}
return res
}
fn ...int |> twice_each() |> ...int {
var n: int
while read(&n) {
yield n * 2
}
}
assert((seq(3) |> sum()) == 6)
assert((seq(3) |> twice_each() |> sum()) == 12)
// Call command by `@command` syntax with pipeline operator
assert(((1, 2) |> @awk('{print $1 + $2}')) == '3')
```
