r"""Return full path to the user-specific log dir for this application.
"appname" is the name of application.
If None, just the system directory is returned.
"appauthor" (only used on Windows) is the name of the
appauthor or distributing body for this application. Typically
it is the owning company name. This falls back to appname. You may
pass False to disable it.
"version" is an optional version path element to append to the
path. You might want to use this if you want multiple versions
of your app to be able to run independently. If used, this
would typically be "<major>.<minor>".
Only applied when appname is present.
"opinion" (boolean) can be False to disable the appending of
"Logs" to the base app data dir for Windows, and "log" to the
base cache dir for Unix. See discussion below.
Typical user cache directories are:
Mac OS X: ~/Library/Logs/<AppName>
Unix: ~/.cache/<AppName>/log # or under $XDG_CACHE_HOME if defined
Win XP: C:\Documents and Settings\<username>\Local Settings\Application Data\<AppAuthor>\<AppName>\Logs
Vista: C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Logs
On Windows the only suggestion in the MSDN docs is that local settings
go in the `CSIDL_LOCAL_APPDATA` directory. (Note: I'm interested in
examples of what some windows apps use for a logs dir.)
OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA`
value for Windows and appends "log" to the user cache dir for Unix.
This can be disabled with the `opinion=False` option.

Pluggable Distributions of Python Software
==========================================
Distributions
-------------
A "Distribution" is a collection of files that represent a "Release" of a
"Project" as of a particular point in time, denoted by a
"Version"::
>>> import sys, pkg_resources
>>> from pkg_resources import Distribution
>>> Distribution(project_name="Foo", version="1.2")
Foo 1.2
Distributions have a location, which can be a filename, URL, or really anything
else you care to use::
>>> dist = Distribution(
... location="http://example.com/something",
... project_name="Bar", version="0.9"
... )
>>> dist
Bar 0.9 (http://example.com/something)
Distributions have various introspectable attributes::
>>> dist.location
'http://example.com/something'
>>> dist.project_name
'Bar'
>>> dist.version
'0.9'
>>> dist.py_version == sys.version[:3]
True
>>> print(dist.platform)
None
Including various computed attributes::
>>> from pkg_resources import parse_version
>>> dist.parsed_version == parse_version(dist.version)
True
>>> dist.key # case-insensitive form of the project name
'bar'
Distributions are compared (and hashed) by version first::
>>> Distribution(version='1.0') == Distribution(version='1.0')
True
>>> Distribution(version='1.0') == Distribution(version='1.1')
False
>>> Distribution(version='1.0') < Distribution(version='1.1')
True
but also by project name (case-insensitive), platform, Python version,
location, etc.::
>>> Distribution(project_name="Foo",version="1.0") == \
... Distribution(project_name="Foo",version="1.0")
True
>>> Distribution(project_name="Foo",version="1.0") == \
... Distribution(project_name="foo",version="1.0")
True
>>> Distribution(project_name="Foo",version="1.0") == \
... Distribution(project_name="Foo",version="1.1")
False
>>> Distribution(project_name="Foo",py_version="2.3",version="1.0") == \
... Distribution(project_name="Foo",py_version="2.4",version="1.0")
False
>>> Distribution(location="spam",version="1.0") == \
... Distribution(location="spam",version="1.0")
True
>>> Distribution(location="spam",version="1.0") == \
... Distribution(location="baz",version="1.0")
False
Hash and compare distribution by prio/plat
Get version from metadata
provider capabilities
egg_name()
as_requirement()
from_location, from_filename (w/path normalization)
Releases may have zero or more "Requirements", which indicate
what releases of another project the release requires in order to
function. A Requirement names the other project, expresses some criteria
as to what releases of that project are acceptable, and lists any "Extras"
that the requiring release may need from that project. (An Extra is an
optional feature of a Release, that can only be used if its additional
Requirements are satisfied.)
The Working Set
---------------
A collection of active distributions is called a Working Set. Note that a
Working Set can contain any importable distribution, not just pluggable ones.
For example, the Python standard library is an importable distribution that
will usually be part of the Working Set, even though it is not pluggable.
Similarly, when you are doing development work on a project, the files you are
editing are also a Distribution. (And, with a little attention to the
directory names used, and including some additional metadata, such a
"development distribution" can be made pluggable as well.)
>>> from pkg_resources import WorkingSet
A working set's entries are the sys.path entries that correspond to the active
distributions. By default, the working set's entries are the items on
``sys.path``::
>>> ws = WorkingSet()
>>> ws.entries == sys.path
True
But you can also create an empty working set explicitly, and add distributions
to it::
>>> ws = WorkingSet([])
>>> ws.add(dist)
>>> ws.entries
['http://example.com/something']
>>> dist in ws
True
>>> Distribution('foo',version="") in ws
False
And you can iterate over its distributions::
>>> list(ws)
[Bar 0.9 (http://example.com/something)]
Adding the same distribution more than once is a no-op::
>>> ws.add(dist)
>>> list(ws)
[Bar 0.9 (http://example.com/something)]
For that matter, adding multiple distributions for the same project also does
nothing, because a working set can only hold one active distribution per
project -- the first one added to it::
>>> ws.add(
... Distribution(
... 'http://example.com/something', project_name="Bar",
... version="7.2"
... )
... )
>>> list(ws)
[Bar 0.9 (http://example.com/something)]
You can append a path entry to a working set using ``add_entry()``::
>>> ws.entries
['http://example.com/something']
>>> ws.add_entry(pkg_resources.__file__)
>>> ws.entries
['http://example.com/something', '...pkg_resources...']
Multiple additions result in multiple entries, even if the entry is already in
the working set (because ``sys.path`` can contain the same entry more than
once)::
>>> ws.add_entry(pkg_resources.__file__)
>>> ws.entries
['...example.com...', '...pkg_resources...', '...pkg_resources...']
And you can specify the path entry a distribution was found under, using the
optional second parameter to ``add()``::
>>> ws = WorkingSet([])
>>> ws.add(dist,"foo")
>>> ws.entries
['foo']
But even if a distribution is found under multiple path entries, it still only
shows up once when iterating the working set:
>>> ws.add_entry(ws.entries[0])
>>> list(ws)
[Bar 0.9 (http://example.com/something)]
You can ask a WorkingSet to ``find()`` a distribution matching a requirement::
>>> from pkg_resources import Requirement
>>> print(ws.find(Requirement.parse("Foo==1.0"))) # no match, return None
None
>>> ws.find(Requirement.parse("Bar==0.9")) # match, return distribution
Bar 0.9 (http://example.com/something)
Note that asking for a conflicting version of a distribution already in a
working set triggers a ``pkg_resources.VersionConflict`` error:
>>> try:
... ws.find(Requirement.parse("Bar==1.0"))
... except pkg_resources.VersionConflict as exc:
... print(str(exc))
... else:
... raise AssertionError("VersionConflict was not raised")
(Bar 0.9 (http://example.com/something), Requirement.parse('Bar==1.0'))
You can subscribe a callback function to receive notifications whenever a new
distribution is added to a working set. The callback is immediately invoked
once for each existing distribution in the working set, and then is called
again for new distributions added thereafter::
>>> def added(dist): print("Added %s" % dist)
>>> ws.subscribe(added)
Added Bar 0.9
>>> foo12 = Distribution(project_name="Foo", version="1.2", location="f12")
>>> ws.add(foo12)
Added Foo 1.2
Note, however, that only the first distribution added for a given project name
will trigger a callback, even during the initial ``subscribe()`` callback::
>>> foo14 = Distribution(project_name="Foo", version="1.4", location="f14")
>>> ws.add(foo14) # no callback, because Foo 1.2 is already active
>>> ws = WorkingSet([])
>>> ws.add(foo12)
>>> ws.add(foo14)
>>> ws.subscribe(added)
Added Foo 1.2
And adding a callback more than once has no effect, either::
>>> ws.subscribe(added) # no callbacks
# and no double-callbacks on subsequent additions, either
>>> just_a_test = Distribution(project_name="JustATest", version="0.99")
>>> ws.add(just_a_test)
Added JustATest 0.99
Finding Plugins
---------------
``WorkingSet`` objects can be used to figure out what plugins in an
``Environment`` can be loaded without any resolution errors::
>>> from pkg_resources import Environment
>>> plugins = Environment([]) # normally, a list of plugin directories
>>> plugins.add(foo12)
>>> plugins.add(foo14)
>>> plugins.add(just_a_test)
In the simplest case, we just get the newest version of each distribution in
the plugin environment::
>>> ws = WorkingSet([])
>>> ws.find_plugins(plugins)
([JustATest 0.99, Foo 1.4 (f14)], {})
But if there's a problem with a version conflict or missing requirements, the
method falls back to older versions, and the error info dict will contain an
exception instance for each unloadable plugin::
>>> ws.add(foo12) # this will conflict with Foo 1.4
>>> ws.find_plugins(plugins)
([JustATest 0.99, Foo 1.2 (f12)], {Foo 1.4 (f14): VersionConflict(...)})
But if you disallow fallbacks, the failed plugin will be skipped instead of
trying older versions::
>>> ws.find_plugins(plugins, fallback=False)
([JustATest 0.99], {Foo 1.4 (f14): VersionConflict(...)})
Platform Compatibility Rules
----------------------------
On the Mac, there are potential compatibility issues for modules compiled
on newer versions of Mac OS X than what the user is running. Additionally,
Mac OS X will soon have two platforms to contend with: Intel and PowerPC.
Basic equality works as on other platforms::
>>> from pkg_resources import compatible_platforms as cp
>>> reqd = 'macosx-10.4-ppc'
>>> cp(reqd, reqd)
True
>>> cp("win32", reqd)
False
Distributions made on other machine types are not compatible::
>>> cp("macosx-10.4-i386", reqd)
False
Distributions made on earlier versions of the OS are compatible, as
long as they are from the same top-level version. The patchlevel version
number does not matter::
>>> cp("macosx-10.4-ppc", reqd)
True
>>> cp("macosx-10.3-ppc", reqd)
True
>>> cp("macosx-10.5-ppc", reqd)
False
>>> cp("macosx-9.5-ppc", reqd)
False
Backwards compatibility for packages made via earlier versions of
setuptools is provided as well::
>>> cp("darwin-8.2.0-Power_Macintosh", reqd)
True
>>> cp("darwin-7.2.0-Power_Macintosh", reqd)
True
>>> cp("darwin-8.2.0-Power_Macintosh", "macosx-10.3-ppc")
False
Environment Markers
-------------------
>>> from pkg_resources import invalid_marker as im, evaluate_marker as em
>>> import os
>>> print(im("sys_platform"))
Invalid marker: 'sys_platform', parse error at ''
>>> print(im("sys_platform=="))
Invalid marker: 'sys_platform==', parse error at ''
>>> print(im("sys_platform=='win32'"))
False
>>> print(im("sys=='x'"))
Invalid marker: "sys=='x'", parse error at "sys=='x'"
>>> print(im("(extra)"))
Invalid marker: '(extra)', parse error at ')'
>>> print(im("(extra"))

>>> print(im("'x'=='y' and os.open('foo')=='y'")) # no short-circuit!
Invalid marker: "'x'=='y' and os.open('foo')=='y'", parse error at 'and os.o'
>>> print(im("'x'=='x' or os.open('foo')=='y'")) # no short-circuit!
