1. Why ';' separation, instead of tabs as in PEP 262? Aren't semicolons a
valid character in filenames?
I am changing this into a <tab>. for now.
What about Antoine's idea about doing a quote() on the names ?
From my point of view <tabs> seems more simple to deal with, if 3rd-party
tools want to work on these files without using pkgutil or Python.
4. There should probably be a way to iterate over the projects in a
directory, since it's otherwise impossible for an installation tool to find
out what project(s) "own" a file that conflicts with something being
installed. Alternatively, reshaping the file API to allow querying by path
as well as by project might work.
I am adding a "get_projects" api:
get_projects() -> iterator
Provides an iterator that will return (name, path) tuples, where `name`
is the name of a registered project and `path` the path to its `egg-info`
directory.
But for the use case you are mentioning, what about an explicit API:
get_owners(paths) -> sequence of project names
returns a sequence of tuple. For each path in the "paths" list, a
tuple of project names
is returned
5. If any cache mechanisms are to be used by the API, the API *must* make it
possible to bypass or explicitly manage that cache, as otherwise
installation tools and tools that manipulate sys.path at runtime may end up
using incorrect data.
work in progress - (I am afraid I have to write an advanced prototype
to be able to know
exaclty how the cache might work, and so, what API we should have)
6. get_files() doesn't document whether the yielded paths are absolute or
relative, local or cross-platform, etc.
I am fixing this as well
I need to find back your comments for this part, I must have missed
them. That's
the last part I didn't work out yet on the current PEP revision.
Well, if you can't find them, the EggFormats doc explains how these file/dir
structures are currently laid out by setuptools, easy_install, pip, etc.,
and the PEP should probably reference that.
work in progress
Is it Pythonic for the methods to starts with "get_", or should they be
projects(), owners(), etc?
