Compile Go to C, with a generic library contains Go core features, like goroutine,channel,GC.

That's will generate minimal binary. The farther plan is compile any Go package to C.

### The pain of Go

* Too large binary size

* Not zero cost call with C

* Builtin string/array/map no methods

* Too verbosity error handling, not like the Go2 `try` error handling proposal

### Features

* goroutine

* channel

* defer

* GC

* CGO

* interface

* closure

* string/array/map with lot builtin methods

* `catch` statement error handling (https://github.com/kitech/cygo/blob/0f213381f06116d0f6f2ca6bf2ccbe70ab088882/bysrc/tpkgs/catch2/t.go#L18)

* unused var warning, not error

* for range => for in

* type foo struct => struct foo

* unsafe.Pointer => voidptr

* uintptr => usize

* seamless C symbol use

* zero cost C call

* all variables reference

### Install

```

cd $GOPATH

git clone https://github.com/kitech/cygo

cd cygo/bysrc

go build -o cygo

```

### Example

```

./cygo ./tpkgs/hello

cmake .

make

```

Source code structure:

* main compiler source https://github.com/kitech/cygo/tree/master/bysrc/

* goroutine/channel implemention in C https://github.com/kitech/cygo/tree/master/corona-c/

* some go stdlib implemention https://github.com/kitech/cygo/tree/master/xgo/

### Supported important syntax

* defer

* closure

* select

### Todos

* [ ] dynamic stack resize

* [ ] correct and more safe point for GC

* [ ] support more OS/platforms

* [ ] so much to do

### Supported original Go packages

* unsafe

* errors

* minigo

* tinygo
