11[![PureScript](https://raw.githubusercontent.com/purescript/purescript/master/logo.png)](http://purescript.org)

3−This is a platform-native compiler backend for [PureScript](https://github.com/purescript/purescript). It attempts to generate "sane", debuggable, and portable [C++11](https://isocpp.org/wiki/faq/cpp11) (or later) or [Go](https://golang.org/) code as an intermediate language, which is then compiled to a native executable binary. This also enables easy interoperability with existing C/C++ or Go frameworks and libraries on a number of platforms.

3+This is an experimental C++11 (or later) compiler backend for [PureScript](https://github.com/purescript/purescript). It attempts to generate "sane", debuggable, and portable C++ code as an intermediate language, which is then compiled to a native executable binary. This enables easy interoperability with existing C/C++ frameworks and libraries on a number of platforms.

5−There are two utilities in the purescript-native "suite": `pscpp` and `psgo`. The source code in this branch is for `psgo`, the purescript-to-Go transpiler. For the source code of the `pscpp` purescript-to-C++ transpiler, please see the [cpp branch](https://github.com/andyarvanitis/purescript-native/tree/cpp).

5+---

7+### **Please note that this project supersedes [pure11](https://github.com/pure11/pure11)**

9+#### Please see [changes](https://github.com/andyarvanitis/purescript-native/wiki/changes) for more details.

713#### Platforms

8−* Although purescript-native should work on any platform supporting PureScript and modern C++ or Go, the generated code and resulting binary executables have been tested on:

9− * macOS Mojave 10.14.5 – full test suite

10− * For C++, Xcode 10.2.1's `clang` was used

11− * For Go, `go` version 1.12.7 was used

12− * Windows 10 x64 – full test suite

13− * C++: Visual Studio 2017 and `clang`

14− * Go: `go` version 1.12.7

15− * Linux Debian 9.5 amd64 – full test suite (C++)

16− * Default versions of `clang` and `gcc`

17− * Linux Debian 10 amd64 – full test suite (Go)

18− * Default version of `go`

19− * Raspberry Pi 3 B+ Raspbian official build (ARM), default versions of `clang` and `gcc`

14+* Generated C++ code and resulting binary executables tested (to at least some extent) on:

15+ * macOS Mojave, Xcode 10.1's clang (full test suite)

16+ * Windows 10 x64 and x86, Visual Studio 2017

17+ * Linux Debian 9.5 amd64, default versions of clang and gcc/g++ (full test suite)

18+ * Raspberry Pi 3 B+ Raspbian official build (ARM), default versions of clang and gcc/g++

19+

20+#### Performance

21+

22+* No runtime system beyond some support classes and the standard C++11 (or later) runtime library

23+* For automatic memory management, uses native C++11 reference counting (`std::shared_ptr`)

24+* Uses PureScript's normal tail call optimization techniques for generated C++ code

25+

26+#### Differences from PureScript:

27+

28+* Foreign imports/exports are C++ instead of JavaScript – see [FFI notes](https://github.com/andyarvanitis/purescript-native/wiki/FFI) and [standard library foreign implementations](https://github.com/andyarvanitis/purescript-native-ffi)

29+* No C++-specific REPL

30+

31+#### Other notes:

32+

33+* PureScript arrays are implemented using [`std::vector`](http://en.cppreference.com/w/cpp/container/vector)

34+* `String` types are implemented with C++11 `u8` literals (UTF-8) and `std::string`

35+* `Number` is C++ `double`, `Int` is C++ `int`, `Char` is `std::string` (single UTF-8 entity), `Boolean` is `bool`

36+

37+#### Future ideas:

38+

39+* Nice facilities (modules) for concurrency/parallelism, using `std::thread`, `std::async`, etc. under the hood (output is already generally thread-safe for immutable values, thanks to `std::shared_ptr`)

40+

41+#### Requirements for building the compiler itself

42+

43+* [Haskell Stack](https://docs.haskellstack.org/en/stable/README/) (if you're running macOS 10.13+, you can use pre-built binaries from [here](https://github.com/andyarvanitis/purescript-native/releases/))

44+

45+#### Requirements for using it

46+

47+* A recent version (0.12+) of [purescript](https://github.com/purescript/purescript/releases).

2048

49+* A C++11-capable toolchain, e.g. recent versions of clang, gcc, Microsoft Visual Studio

50+* GNU Make is the default supported build tool, but you should be able to use your favorite C++ build system, tools, debuggers, etc.

2151

22−#### Requirements for building `pscpp` and `psgo`

52+#### Getting Started

53+This assumes you are running macOS (OS X) or a Unix-like system (Linux, *BSD, etc.).

2354

24−* [Haskell Stack](https://docs.haskellstack.org/en/stable/README/) (if you're running macOS 10.14.5+, you can use pre-built binaries from [here](https://github.com/andyarvanitis/purescript-native/releases/))

55+1. Make sure you have developer tools for your system installed. For macOS, you'll need a recent version of Xcode. For Linux, etc., you can use clang 3.5 or later, or gcc/g++ 4.9.2 or later.

2556

26−#### Requirements for using PureScript + purescript-native

57+2. Create a working directory wherever you like, and a `src` subdirectory under it, which will be where you will place your own PureScript source files.

2758

28−* A recent version (0.13+) of [purescript](https://github.com/purescript/purescript/releases).

59+3. Under your working directory, also create an `ffi` subdirectory, which will be where you will place C/C++ FFI source files. You should at least add the contents of [purescript-native-ffi](https://github.com/andyarvanitis/purescript-native-ffi) into this directory, in addition to any of your own foreign implementations.

2960

30−* For `pscpp`, a C++11-capable toolchain, e.g. recent versions of clang, gcc, Microsoft Visual Studio

31− * GNU Make + `psc-package` is the default supported build tool, but you should be able to use your favorite package manager, C++ build system, tools, debuggers, etc.

32−* For `psgo`, the [Go toolchain](https://golang.org) for your system

33− * You can use your favorite PureScript package manager and build tools – but for simplicity, [`spago`](https://github.com/spacchetti/spago) is recommended.

61+4. Generate the default GNU `Makefile` in your working directory by running `pscpp --makefile`.

3462

63+5. Use PureScript's standard [`psc-package`](https://psc-package.readthedocs.io/en/latest/) utility to add and manage package dependencies.

3564

36−#### For more information and a Getting Started guide, please see

37−* [`pscpp`](https://github.com/andyarvanitis/purescript-native/blob/cpp/README-cpp.md)

38−* [`psgo`](https://github.com/andyarvanitis/purescript-native/blob/golang/README-go.md)

65+6. You should now be ready to build a PureScript program:

66+ * As stated above, place your source file(s) in the working directory's `src` subdirectory and execute `make debug` or `make release`. If your build machine has multiple cores, you might want to append `-jN` to your *make* command, where `N` is the number of cores.

3967

68+ * This will generate the C++ source tree for your program and then build an executable binary. The resulting executable will be in the `bin` subdirectory under the output directory and called `main` (so `output/bin/main`, by default). Source files will be under `src` (`output/src/` by default).
