5−## Finding Issues to Work On
6−
7−If you would like to contribute, please consider the issues in the current milestone first. If you are a new contributor, you may want to have a go at the ["easy" issues](https://github.com/purescript/purescript/labels/easy) to get started.
8−
9−## Pull Requests
10−
11−Please follow the following guidelines:
12−
13−- Add at least a test to `examples/passing/` and possibly to `examples/failing`.
14−- Build the binaries and libs with `cabal build`
15−- Install the binaries and libs with `cabal install`.
16−- Run `cabal configure --enable-tests && cabal build && cabal test` to build the test suite. You will need `npm` and `node` on your PATH to run the tests.
17−- Build the core libraries by running the script in `core-tests`.
18−
19−## Code Review
20−
21−To prevent core libraries from getting broken, every change must be reviewed. A pull request will be merged as long as one other team member has verified the changes.
22−
23−## Adding Dependencies
24−
25−Because the PureScript compiler is distributed in binary form, we include
26−the licenses of all dependencies, including transitive ones, in the LICENSE

1−# Installation information
2−
3−If you are having difficulty installing the PureScript compiler, feel free to
4−ask for help! A good place is the #purescript IRC channel on Freenode, or
5−alternatively Stack Overflow.
6−
7−## Using prebuilt binaries
8−
9−The prebuilt binaries are compiled with GHC 7.8.4, and therefore they should
10−run on any operating system supported by GHC 7.8.4, such as:
11−
12−* Windows 2000 or later,
13−* OS X 10.7 or later,
14−* Linux ??? (we're not sure what the minimum version is).
15−
16−This list is not exhaustive. If your OS is too old or not listed, or if the
17−binaries fail to run, you may be able to install the compiler by building it
18−from source; see below.
19−
20−It's probably safe to assume that other prebuilt distributions (eg, Homebrew,
21−Chocolatey, AUR, npm) use the same binaries, and therefore have the same
22−requirements.
23−
24−## Compiling from source
25−
26−GHC 7.6.1 or newer is required to compile from source. The easiest way is to
27−use stack:
28−
29−```
30−$ stack install purescript
31−```
32−
33−This will then copy the compiler and utilities into `~/.local/bin`.
34−
35−
36−If you don't have stack installed yet there are install instructions
37−[here](https://github.com/commercialhaskell/stack/blob/master/doc/install_and_upgrade.md).
38−
39−If you don't have ghc installed yet, stack will prompt you to run `stack setup`
40−which will install ghc for you.
41−
42−The PureScript compiler has been known to run on OS X 10.6 when built with GHC
43−7.6.
44−
45−
46−## The "curses" library
47−
48−`psci` depends on the `curses` library (via the Haskell package `terminfo`). If
49−you are having difficulty running the compiler, it may be because the `curses`
50−library is missing.
51−
52−On Linux, you will probably need to install `ncurses` manually. On Ubuntu, for
53−example, this can be done by running:
54−
55−```
56−$ sudo apt-get install libncurses5-dev
57−```

4+#### Performance
5+
6+* No runtime system beyond some support types and functions
7+* Uses PureScript's normal tail call optimization techniques for generated Go code
8+
9+#### Differences from PureScript:
10+
11+* Foreign imports/exports are Go instead of JavaScript – see [standard library foreign implementations](https://github.com/andyarvanitis/purescript-native-go-ffi)
12+* No Go-specific REPL
13+
14+#### Other notes:
15+
16+* The provided `Any` type is just an alias for `interface{}`
17+* PureScript types are represented in Go with:
18+
19+ | PureScript | Go |
20+ |------------|----|
21+ |`Array` | `[]Any`|
22+ |`String` | `string`|
23+ |`Number` | `float64`|
24+ |`Int` | `int`|
25+ |`Char` | `string` (single UTF-8 entity)|
26+ |`Boolean` | `bool`|
27+ |Records | `map[string]Any`|
28+
29+#### Future ideas:
30+
31+* Nice facilities (modules) for concurrency/parallelism, using goroutines
32+
33+
34+#### Getting Started
35+This assumes you are running macOS (OS X) or a Unix-like system (Linux, *BSD, etc.).
36+
37+1. Choose a working directory wherever you like. Then create a `src` subdirectory under it, which will be where you will place your own PureScript source files.
38+
39+1. Initialize your project with `spago init`, and install any dependencies with `spago install` (please see their instructions if you haven't used it before).
40+
41+1. Add the `backend = "psgo"` option to your `spago.dhall` file. That way `spago` will use the psgo backend when compiling.
42+
43+1. You should now be ready to build a PureScript program:
44+ * As stated above, place your source file(s) in the working directory's `src` subdirectory and execute `spago build`.
45+
46+ * This will generate the Go source tree for your program and then build an executable binary. The resulting executable will be in your working directory and will be named `Main`. The generated source files will be under `output/`.

3−A small strongly typed programming language with expressive types that compiles to Javascript, written in and inspired by Haskell.
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.

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).

7+#### 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`

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.

167−-- Returns the uncovered set of binders
168−-- the first argument is the list of uncovered binders at step i
169−-- the second argument is the (i+1)th clause of a pattern matching definition
170−--
171−-- The idea of the algorithm is as follows:
172−-- it processes each binder of the two lists (say, `x` and `y`) one by one
173−-- at each step two cases arises:
174−-- - there are no missing cases between `x` and `y`: this is very straightforward, it continues with the remaining cases
175−-- but keeps the uncovered binder in its position.
176−-- - there are missing cases, let us call it the set `U`: on the one hand, we mix each new uncovered case in `U`
177−-- with the current tail of uncovered set. On the other hand, it continues with the remaining cases: here we
178−-- can use `x` (but it will generate overlapping cases), or `y`, which will generate non-overlapping cases.
179−--
180−-- As an example, consider:
181−--
182−-- data N = Z | S N
183−-- f Z Z = Z --> {[S _, _], [Z, S _]} which are the right non-overlapping cases (GHC uses this).
184−--
185−-- if we use `x` instead of `y` (in this case, `y` stands for `Z` and `x` for `_`) we obtain:
186−-- f Z Z = Z --> {[S _, _], [_, S _]} you can see that both cases overlaps each other.
187−--
188−-- Up to now, we've decided to use `x` just because we expect to generate uncovered cases which might be
189−-- redundant or not, but uncovered at least. If we use `y` instead, we'll need to have a redundancy checker
190−-- (which ought to be available soon), or increase the complexity of the algorithm.
