# Calypso

[](#contributors-)
Calypso is a mostly imperative language with some functional influences that is focused on flexibility and simplicity.
Note that this code is very work-in-progress. Contributions are welcome (and encouraged!), but it's not recommended to use this in production unless you're ready for some serious pain. Or code that just doesn't work.
## Example
The following example is an implementation of [FizzBuzz](https://en.wikipedia.org/wiki/Fizz_buzz) that goes until a number specified in the CLI arguments of the program, or 100 if that is not present. Note that this is currently psuedocode and may change.
```zig
import standard.process.Args
fn main(args: Args) ->
args
|> _.get(0)
|> _.unwrap_or("100")
|> uint.from_string
|> _.unwrap_or(100)
|> fizzbuzz
|> _.each(&println("{}", &1))
fn fizzbuzz(max: uint): [string] ->
1.to_incl(max).map(fn n ->
case do
15.divides(n) -> "FizzBuzz",
3.divides(n) -> "Fizz",
5.divides(n) -> "Buzz",
_ -> n.to_string
end)
```
## Compatibility
The MSRV (Minimum Supported Rust Version) is currently Rust 1.66.1.
Calypso is automatically tested on:
- x86_64 linux, Rust 1.66.1
- x86_64 linux, latest stable
- x86_64 linux, latest nightly
as well as manually tested on x86_64 linux with the latest stable build of Rust
Calypso is developed and tested on these platforms:
- Arch Linux, latest stable
- I'd hope there's more in the future...but I don't currently have the infra to test those :(

## SaturnVM
SaturnVM is the VM I'm writing for Calypso. It's meant to be mostly standalone but at the moment there may be some connections or dependencies between it and Calypso. SaturnVM's top-level crate can be found in `libs/saturnvm` and some of its subcrates will be found in `libs/` under the name `saturnvm_*`. The `calypso_vm` crate will probably be a Calypso-specific interface to SaturnVM.
For more information, see [its README](libs/saturnvm/README.md).
