find GAE SDK path from system(XP) "PATH" about google-app-engine-django HOT 7 CLOSED

I assume you are manually adding the SDK path to the PATH environment variable?

If you're going to this effort why not add it to PYTHONPATH? Then it will be
automatically imported and no code changes in the helper will be required.

Please re-open if you have further information.

The google installer for windows kindly sets the path environment. It is 
available 
in the registry under HKEY_CURRENT_USER.Environment.Path and under the system 
environment settings. You can use _winreg or the simpler method proposed by 
qxodream.
Both are better than guessing.

wpaths = os.environ['PATH'].split(";")
for tmp_path in wpaths:
  if tmp_path.count('google_appengine') > 0:      
     paths.append(tmp_path.rstrip('\\'))

The use of Drive:\\Program Files is useless unless you actually accept the 
installer 
default installation path. Many developers do development on drives other than 
C. 
Other developers refuse to install in Program Files - especially on vista.

This should be resolved in r32 which uses a win32 api function to find the SDK
without needing to assume the drive letter or that Program Files is on the same 
drive
as Windows itself.

The code in r32 asks windows for the the path for program files. I however, 
naively 
instructed the installer to install in E:\Google. It could have been E:\myGoog. 
That 
is a both a perfectly valid choice and quite a normal one on Windows. If you 
run the 
msi installer a second time, it will ask if you would like to repair or delete 
the 
installation - it knows I installed to E:\Google. The code in r32 
unsurprisingly 
then, does not find the appengine.

My point earlier, was that the appengine msi installer does conveniently add 
(or 
modify) it's install path in the windows path environment variable. This then  
presents itself in os.environ['PATH']. I guess whoever coded the installer 
thought 
this was a good decision.

I've committed some code to implement this in r50.

Thanks for the suggestions
