# Name: wxversion
# Purpose: Allows a wxPython program to search for alternate
# installations of the wxPython packages and modify sys.path
# so they will be found when "import wx" is done.

"""
If you have more than one version of wxPython installed this module
allows your application to choose which version of wxPython will be
imported when it does 'import wx'. The main function of this module
is `select` and you use it like this::
import wxversion
wxversion.select('2.4')
import wx
Or additional build options can also be selected, although they will
not be required if they are not installed, like this::
import wxversion
wxversion.select('2.5.3-unicode')
import wx
Or you can require an exact match on the build options like this::
import wxversion
wxversion.select('2.5.3-unicode', optionsRequired=True)
import wx
Finally you can also specify a collection of versions that are allowed
by your application, like this::
import wxversion
wxversion.select(['2.5.4', '2.5.5', '2.6'])
import wx
Of course the default wxPython version can also be controlled by
setting PYTHONPATH or by editing the wx.pth path configuration file,
but using wxversion will allow an application to manage the version
selection itself rather than depend on the user to setup the
environment correctly.
It works by searching the sys.path for directories matching wx-* and
then comparing them to what was passed to the select function. If a
match is found then that path is inserted into sys.path.
NOTE: If you are making a 'bundle' of your application with a tool
like py2exe then you should *not* use the wxversion module since it
looks at the filesystem for the directories on sys.path, it will fail
in a bundled environment. Instead you should simply ensure that the
version of wxPython that you want is found by default on the sys.path
when making the bundled version by setting PYTHONPATH. Then that
version will be included in your bundle and your app will work as
expected. Py2exe and the others usually have a way to tell at runtime
if they are running from a bundle or running raw, so you can check
that and only use wxversion if needed. For example, for py2exe::
if not hasattr(sys, 'frozen'):
import wxversion
wxversion.select('2.5')
import wx
More documentation on wxversion and multi-version installs can be
found at: http://wiki.wxpython.org/index.cgi/MultiVersionInstalls

Search for a wxPython installation that matches version. If one
is found then sys.path is modified so that version will be
imported with a 'import wx', otherwise a VersionError exception is
raised. This funciton should only be caled once at the begining
of the application before wxPython is imported.
:param versions: Specifies the version to look for, it can
either be a string or a list of strings. Each string is
compared to the installed wxPythons and the best match is
inserted into the sys.path, allowing an 'import wx' to
find that version.
The version string is composed of the dotted version
number (at least 2 of the 4 components) optionally
followed by hyphen ('-') separated options (wx port,
unicode/ansi, flavour, etc.) A match is determined by how
much of the installed version matches what is given in the
version parameter. If the version number components don't
match then the score is zero, otherwise the score is
increased for every specified optional component that is
specified and that matches.
Please note, however, that it is possible for a match to
be selected that doesn't exactly match the versions
requested. The only component that is required to be
matched is the version number. If you need to require a
match on the other components as well, then please use the
optional ``optionsRequired`` parameter described next.
:param optionsRequired: Allows you to specify that the other
components of the version string (such as the port name
or character type) are also required to be present for an
installed version to be considered a match. Using this
parameter allows you to change the selection from a soft,
as close as possible match to a hard, exact match.
