Python bindings for enry

[bzz]

Same way as we have Java bindings for enry, wrapping a Go library built with -buildmode=c-shared it would be nice to have one for Python using ctypes FFI cffi or something similar.

Particular use case: one want to use https://github.com/bblfsh/sonar-checks/ API that would require knowing a language the file-to-be-checked is written in, to choose the write checks.

TODOs

• Initial PoC: exposes 1-2 API (e.g \wo slices) Initial cffi bindings for python #245
• Minimal: expose only high-level language detection API python: expose highest-level API #250
  (usable from Jupiter, after a manual build to enable Language detection accuracy measurements #246)
• Installable: expose all existing API, with the documentation and setup script
  pip install -e git+https://github.com/src-d/enry.git#egg=python
• Publish: add new release profile to CI for
  • building .whl (linux, macOS)
  • publishing on pypi

ctypes is an ancient deprecated way, cool kids use cffi.

This is just nice-to-have for now: the use case listed above is addressed in lookout by incorporating language in DataServer API src-d/lookout#131

I've started adding it during OSD and will push simple WIP with CPython extension by cffi soon
