README.md

gopy

gopy generates (and compiles) a CPython extension module from a go package.

Installation

$ go get github.com/go-python/gopy

Documentation

Documentation is available on godoc: https://godoc.org/github.com/go-python/gopy

or directly from the command-line prompt:

$ gopy help
gopy - 

Commands:

    bind        generate and compile (C)Python language bindings for Go
    gen         generate (C)Python language bindings for Go

Use "gopy help <command>" for more information about a command.


$ gopy help gen
Usage: gopy gen <go-package-name>

gen generates (C)Python language bindings for a Go package.

ex:
 $ gopy gen [options] <go-package-name>
 $ gopy gen github.com/go-python/gopy/_examples/hi

Options:
  -lang="python": target language for bindings
  -output="": output directory for bindings


$ gopy help bind
Usage: gopy bind <go-package-name>

bind generates and compiles (C)Python language bindings for a Go package.

ex:
 $ gopy bind [options] <go-package-name>
 $ gopy bind github.com/go-python/gopy/_examples/hi

Options:
  -output="": output directory for bindings

Examples

$ gopy bind -output=out github.com/go-python/gopy/_examples/hi
$ ls out
hi.so

$ cd out
$ python2
>>> import hi
>>> dir(hi)
['Add', 'Concat', 'Hello', 'Hi', 'NewPerson', 'Person', '__doc__', '__file__', '__name__', '__package__']

>>> hi.Hello("you")
hello you from go

You can also run:

go test -v -run=TestBind
=== RUN   TestBind
processing "Add"...
processing "Concat"...
processing "Hello"...
processing "Hi"...
processing "NewPerson"...
processing "Person"...
processing "Add"...
processing "Concat"...
processing "Hello"...
processing "Hi"...
processing "NewPerson"...
processing "Person"...
github.com/go-python/gopy/_examples/hi

--- hi.Hi()...
hi from go
--- hi.Hello('you')...
hello you from go
--- hi.Add(1, 41)...

--- hi.Concat('4', '2')...
42
--- doc(hi.Person):
Person is a simple struct

--- p = hi.Person()...

['Age', 'Name', '__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']
--- p.Name: None
--- p.Age: None
--- doc(p):
Person is a simple struct

--- PASS: TestBind (2.13s)
PASS
ok  	github.com/go-python/gopy	2.135s

Limitations

  • wrap go structs into python classes [DONE]
  • better pythonization: turn go errors into python exceptions [DONE]
  • only python-2 supported for now
