from and with keywords

[john.m.baker]

Hello,

I’ve written a set of Python scripts around Python 2.5.4 and have made use of the ‘with’ keyword.  Consider the following:

#!/usr/bin/python

from __future__ import with_statement # This isn't required in Python 2.6

When I attempt to load the script in Jython, I get the following error:

  File "<string>", line 2

    from __future__ import with_statement # This isn't required in Python 2.6

    ^

SyntaxError: no viable alternative at input 'from'

Is ‘from’ not supported in Jython?  Is ‘with’ supported?

Thanks,

John

That likely mean that you added spaces in the line before typing "from".

Both are supported and work well :-)

Your script works just fine for me. Did you use Jython 2.5 ?

Perhaps you have some weird bytes at the start of the file? The error
says "line 2".

Perhaps some bogus Unicode BOM?

Hi

Line 1 had a #!/usr/bin/python, so I've removed it and it still fails:

  File "<string>", line 1
    from __future__ import with_statement
    ^
SyntaxError: no viable alternative at input 'from'

There are no spaces before from.

Can I turn on some extra debugging to get more useful debug?  Or does anyone know the answer?  I'm using Jythin 2.5.1.

Thanks


John

Hi John,

Could you elaborate more on how you install Jython on your environment?

The first line looks like you are invoking jython from your default CPython instead of Jython.

The line 1: #!/usr/bin/python

Could you invoke Jython from your shell/command prompt with that setting?

Regards,

Daniel

Hello,

 

I unzipped the jython package and I can run the jython jar using java –jar jython.jar.  The interpreter works fine.

 

What the instructions lack is how to copy the jython jar and resources elsewhere.  I don’t want to ship the entire jython zip file with my project; I want to place the relevant parts into a war file.

 

The #!/usr/bin/python is irrelevant – it’s there because the script has it, but it still doesn’t work without it.

 

The answer seems to lie in the lib directory – could you tell me how Jython loads resources from it?

 

Thanks,

 

John

If you're deploying in a war, then stick the Lib directory in the "classes" dir (for example), and then point the python path at that directory with something vaguely like:

Properties props = new Properties();
String jythonPath = libDir.getFile().getCanonicalPath();
props.put("python.path", jythonPath);
PythonInterpreter.initialize(System.getProperties(), props, null);

In my case, "libDir" is a prop injected by spring:

<property name="libDir" value="classpath:Lib" />

So you'll need to grab the canonical path according to whatever framework you're working within.

Dunno if that helps?

Yes you can (but that means you can only use java libraries, rather than python modules).  However your question was where to put resources -- and that's how I do it... ;-)

If you need to use the __future__ mod, you'll need to bundle the Lib dir.

If you're deploying in a war, then stick the Lib directory in the "classes" dir (for example), and then point the python path at that directory with something vaguely like:

Properties props = new Properties();
String jythonPath = libDir.getFile().getCanonicalPath();
props.put("python.path", jythonPath);
PythonInterpreter.initialize(System.getProperties(), props, null);

In my case, "libDir" is a prop injected by spring:

<property name="libDir" value="classpath:Lib" />

So you'll need to grab the canonical path according to whatever framework you're working within.

Dunno if that helps?

Hello,

 

I unzipped the jython package and I can run the jython jar using java –jar jython.jar.  The interpreter works fine.

 

What the instructions lack is how to copy the jython jar and resources elsewhere.  I don’t want to ship the entire jython zip file with my project; I want to place the relevant parts into a war file.

 

The #!/usr/bin/python is irrelevant – it’s there because the script has it, but it still doesn’t work without it.

 

The answer seems to lie in the lib directory – could you tell me how Jython loads resources from it?

I’m confused. J  So, what’s the difference between the Java libraries and the Python modules?  My understanding was that Jython makes use of the Python modules, shipped in the Lib directory.  And, my problem was that the Lib directory wasn’t in the jar hence the jar wasn’t portable (i.e. I couldn’t put it in a web app and use it). 

 

You seem to be suggesting that I can use the jar without the Lib directory bundled within it, and some other set of external modules?

Jason,

 

If I have my own library, that I’d usually point at through a .pth file in the site-packages directory, should I point to it through the python.path environment var?

 

I’ve just tried using the code sample below and it failed...

I think not.  But I'm not sure how the site-packages stuff will work when
you're deploying in a war file.  If the war file is exploded it -should-
be fine, but I personally haven't needed to add anything to site-packages.

Is there a reason you can't add your library as a part of your main
scripts directory?

Jason,

Well I'd prefer to use the jar which contains the Lib directory, and I
can't believe Jython doesn't support site-packages?  Surely many people
deploy custom packages?

My reason for preferring to use the full jar containing Lib is to make
deployment as clean as possible, especially when upgrading jython in the
future.

Jython looks for packages on the class path. If you deploy a war file on
tomcat or any java ee webserver, you can just put any custom packages in
a jar or anywhere else on the class path. Jython will find your packages
as long as they are on the classpath.

[Jason R Briggs]

I think you might've misunderstood me.  You *can* use a jar with the Lib
dir, and as far as I'm aware site-packages is supported (someone else
might be able to confirm).  All I'm saying is when you bundle it inside a
war file, I'm not sure how the .pth stuff will work.

Regarding site-packages, I was more questioning the necessity of using it.
 That dir is used when you're providing site-wide extensions for a Python
installation.  In this case you're bundling jython inside a war (so it
doesn't really fit the definition of "site-wide") so you could probably
get away with including the module dir in whatever dir you're storing your
main jython scripts.  If that makes sense...?
