Okonomiyaki is an experimental library aimed at consolidating a lot of our
low-level code used for Enthought's eggs.
The library contains code for the following:
* producing EDM and enpkg-compatible egg from a tree + metadata
* object models for eggs metadata, as well as versions and platform
representations
It works on Python >= 3.6, It is expected to work on pretty
much any compliant python implementation.
Note
----
* Version instances are available without extra dependencies so use ``pip install okonomiyaki``
* Platform instances are available by installing ``pip install okonomiyaki[platforms]``
* Egg metadata and archive tools are available by installing ``pip install okonomiyaki[formats]``
* The full set of functionality, please use ``pip install okonomiyaki[all]``
Examples
========
Version parsing
---------------
To parse versions::
from okonomiyaki.versions import EnpkgVersion
# Every Version class has a from_string constructor
v1 = EnpkgVersion.from_string("1.3.3-1")
v2 = EnpkgVersion.from_string("1.3.2-3")
assert v1 > v2
Version instances are designed to be immutable, and to be used as keys in
dictionaries.
Platform parsing
----------------
To parse epd platform strings (``rh5-64``, ``rh6_x86_64``, etc.) consistently::
from okonomiyaki.platforms import EPDPlatform
# Internal representation is normalized.
rh5_new_name = EPDPlatform.from_string("rh5-x86_64")
rh5_old_name = EPDPlatform.from_string("rh5-64")
assert rh5_old_name == rh5_new_name
As for Version instances, ``EPDPlatform`` instances are designed to be
immutable and to be used as keys in dictionaries.
Egg metadata
------------
To parse Enthought eggs::
from okonomiyaki.file_formats import EggMetadata
# Only works for Enthought eggs
metadata = EggMetadata.from_egg("numpy-1.10.1-1.egg")
print(metadata.metadata_version)
print(metadata.name)
print(metadata.version)
This will take care of a lot of low-level, legacy details you don't want to
know about.
