gothon 0.5.0

Gothon runs GO Code from Python, just import *.go files from Python.

# Gothon

Python 3 modules written on pure Go. No CFFI, no CTypes, no CGo, no PyBindGen, just import `*.go` files from Python.

It works using IPC RPC. Inspired by [Cythons `pyximport`](http://cython.readthedocs.io/en/latest/src/tutorial/cython_tutorial.html?highlight=pyximport#pyximport-cython-compilation-for-developers) and [CPPImport](https://github.com/tbenthompson/cppimport#import-c-or-c-files-directly-from-python). Designed to speed up Python using Go.

# Use

```python
$ ls
gothon.py python_module.go

$ python
Python 3.6.4 (default, Jan 5 2018, 02:35:40)

>>> import gothon # Import & enable Gothon.
>>> gothon.import_hook()
>>> import python_module # Import *.go files.
>>> repr(python_module)
'<Gothon object 140066220608272 from python_module.go>'
>>> python_module.__doc__
'Gothon runs GO Code from Python using IPC RPC JSON.'
>>> worker = python_module.start()
>>> worker.call("Echo.Echo", "Hello from Python to Go")
'Hello from Python to Go'
>>>
```


# Install

```

**Description:**
Gothon runs GO Code from Python using IPC RPC JSON.

Unix Socket are used because from benchmarks it performs 3x faster than TCP/UDP Sockets.

This does not connect to the network, nor internet, nor use HTTP.

Delegates the Parse, Compile, Build and Cache to Go itself.

This project is oriented to Developers, NOT end-users.

This project can be used with Fades, FireJails, Docker, RKT.

This project assumes at least very basic knowledge of the Go programming language.

Feel free to contact us if you need help integrating it on your project.

**Arguments:**
- `go_file` A GO file to compile and run as a python module, string type, defaults to `python_module.go`, required.
- `startup_delay` A startup delay, after building the go file but before returning the IPC RPC to Python, float type, defaults to `0.1`, optional.

**Keyword Arguments:** None.

**Returns:** `gothon.RPCJSONClient()` an custom IPC RPC.

**Base Class:** `object`.

**Type:** `object`.

**Source Code file:** https://github.com/juancarlospaco/gothon/blob/master/gothon.py

| State | OS | Description |
| ------------------ |:-----------:| -----------:|
| :white_check_mark: | **Linux** | Works Ok |
| :white_check_mark: | **Os X** | Works Ok |

**Usage Example:**

```python
>>> from gothon import Gothon
>>> unemployed = Gothon()
>>> worker = unemployed.start()
>>> worker.call("Echo.Echo", "Hello from Python to Go")
'Hello from Python to Go'
>>> worker.stop()
>>>
```

# Requisites

- [Python 3.6+](https://python.org)
- [Go 1.10+](https://golang.org)


##### Troubleshoot

<details>
<summary>Not working</summary>

- Delete all `__pycache__` and `*.pyc`.
- Execute `go clean -x -cache` (Usually Go takes care of cleaning Cache automatically).
- Update your Go to the latest version.

# Why

Things that Ive tried and didnt work (2018, Linux):

- https://blog.filippo.io/building-python-modules-with-go-1-5/ (Go 1.5 only)
- https://github.com/go-python/gopy/issues/83 (Python 2 only)
- https://github.com/go-python/gopy/blob/master/gen.go#L81 (Python 2 only)
- https://github.com/sbinet/go-python (Python 2 only)
- https://dustymabe.com/2016/09/13/sharing-a-go-library-to-python-using-cffi/ (Compiler Errors on embebed obfuscated C)
- http://pybindgen.readthedocs.io/en/latest/tutorial/#supported-python-versions (Compiler Errors on obfuscated C)
- https://hackernoon.com/extending-python-3-in-go-78f3a69552ac (All of the above)
- Other solutions call Python from Go, the reverse of Gothon.
- Others I dont remember the links.
