fix all an error |

@swolchok @gjtorikian could we move forward with this pull-request? |
|
@tsunammis Why are you pinging me? I’m not a maintainer on this project, please don’t do that. |
|
@gjtorikian You are the second contributor, it was just a ping. Sorry. |
|
(Sorry for the delay in responding!) Isn't it possible to write code that works under both Python 2 and Python 3? I don't mind supporting Python 3, but I would rather not duplicate the generator code in order to provide that support. |
|
Yep, it is possible to do so. I wanted to be the less intrusive possible. But yeah i can modify the generator to be python2 and python3 compatible. |
|
@swolchok Done, now the ast/*.py file are runable by python2 or python3. |

Seems pretty straightforward to me. I would like to see some kind of sanity test that can run if python2 and python3 are available to verify that the same output is produced in both cases; that should guard us against both output divergences and also breaking compatibility with one or the other version.

shouldn't this be end=''? (empty string)

I choose to let 2to3.py do its magic and simply correct incompatibilities.
But yeah, this one is strange, I'll look it up.

nit: remove extra blank line

@swolchok I'll add diff tests with python2 and python3. |
|
Any update on this PR? |
|
Yeah, sorry, i'm currently on holydays, i'll finish it when i'll be back, in a week or two. Sorry for the delays. |

Hi @bobh66, i cannot say that i'm maintaining a python3 fork, it's just that I stop the project from requering python 2. As i don't have any use of the 'ctypesgen'erated files, cause i use cffi, i just need the lib to built on an env whithout python2. |

The missing Python 3 support is blocking the inclusion of Tartiflette into the Fedora Package Collection as libgraphqlparser is a dependency. Would be nice if that could be resolved any time soon. |
Hello,
The idea behind this is to have libgraphql not requiring python2 for file generation but also work with python3.
CMakeLists.txt is modified in order to ask for
at leastpython 2 and notonly python 2ast/*.py modified in order to support python2 or python3.
Thanks
