# malgo
[](https://github.com/malgo-lang/malgo/actions?query=workflow%3A%22Malgo+CI%22)
A statically typed functional programming language.
## Requirement
* [stack](https://docs.haskellstack.org/en/stable/README/)
* [bdwgc](http://www.hboehm.info/gc/)
* [clang](https://clang.llvm.org/)
* [llvm](https://llvm.org/)
## Installation
### Installing LLVM
#### Homebrew
```sh
$ brew install llvm-hs/llvm/llvm-12
```
#### Debian/Ubuntu
```
$ apt-get install llvm-9-dev
```
### Installing Malgo
```sh
$ git clone https://github.com/malgo-lang/malgo
$ cd malgo
$ stack install
$ ./scripts/install_malgo_internal.sh
```
## Usage
```sh
$ ./scripts/compile.sh examples/malgo/Hello.mlg
$ ./Hello
Hello, world
```
## Examples
### Hello, world
```
module Hello = {
module {..} = import Builtin;
module {..} = import Prelude;
main = {
putStrLn "Hello, world!"
};
}
```
### Fibonacci number
```
module Fib = {
module {..} = import Builtin;
module {..} = import Prelude;
infix 4 (<=);
(<=) = { x y -> leInt32 x y };
infixl 6 (+);
(+) = { x y -> addInt32 x y };
infixl 6 (-);
(-) = { x y -> subInt32 x y };
fib = { n ->
if (n <= 1)
{ 1 }
{ fib (n - 1) + fib (n - 2) }
};
main = {
fib 5 |> toStringInt32 |> putStrLn
};
}
```
### List operations
```
module List = {
module {..} = import Builtin;
module {..} = import Prelude;
infix 4 (<=);
(<=) : Int32 -> Int32 -> Bool;
(<=) = {x y -> leInt32 x y};
infixl 6 (+);
(+) : Int32 -> Int32 -> Int32;
(+) = {x y -> addInt32 x y};
infixl 6 (-);
(-) : Int32 -> Int32 -> Int32;
(-) = {x y -> subInt32 x y};
map : (a -> b) -> List a -> List b;
map = { _ Nil -> Nil
| f (Cons x xs) -> Cons (f x) (map f xs)
};
sum : List Int32 -> Int32;
sum = { Nil -> 0
| Cons x xs -> x + sum xs
};
-- [0 .. n]
below : Int32 -> List Int32;
below = { n ->
if (n <= 0)
{ [0] }
{ Cons n (below (n - 1)) }
};
main = {
sum (map (addInt32 1) (below 10))
|> toStringInt32
|> putStrLn
};
}
```

## TODO
[Malgo タスクリスト \- 星にゃーんのScrapbox](https://scrapbox.io/takoeight0821/Malgo_%E3%82%BF%E3%82%B9%E3%82%AF%E3%83%AA%E3%82%B9%E3%83%88)
## Compilation issue on macOS
In my case, `stack build` says:
```
llvm-hs> error: dyld[89679]: Library not loaded: @rpath/libc++abi.1.dylib
llvm-hs> Referenced from: /usr/local/Cellar/llvm-12/12_2/lib/llvm-12/lib/libc++.1.0.dylib
llvm-hs> Reason: tried: '/usr/local/lib/libc++abi.1.dylib' (no such file), '/usr/lib/libc++abi.1.dylib' (no such file)
```
I don't know exactly what caused this. However, I was able to solve it with `ln -s /usr/local/lib/libc++abi.1.dylib /usr/local/Cellar/llvm-12/12/12_2/lib/llvm-12/lib/lib/libc++.1.0.dylib`.
## How to Test
```sh
# full test (parallel)
cabal test --test-show-details=streaming
# full test (serial)
cabal test --test-show-details=streaming --test-options='-j1'
# usual case (all optimization enabled) only
cabal test --test-show-details=streaming --test-options='--match "usual"'
# no all optimization case only
cabal test --test-show-details=streaming --test-options='--match "nono"'
# no lambda-lift optimization case only
cabal test --test-show-details=streaming --test-options='--match "nolift"'
# no other optimization case only
cabal test --test-show-details=streaming --test-options='--match "noopt"'
cabal exec malgo
