See, my powers of stupidity are legendary. Smile

I updated the one-liner code sample on the mod_python page (near the
part that points to python_example.py) to include the def fsapi line.

Works like a champ now! Thanks!

could make a good addition to the wiki

Greetings,

know where you think a good home for this info might be on the

I'm guessing I haven't done everything necessary to enable
python on my
machine. I have python-2.4.3 and python-devel 2.4.3-21
installed on the
FS machine.

Per the instructions, I uncommented the mod_python line from
modules.conf and rebuilt my freeswitch instance. Vanilla
functionality
is working. I set PYTHONPATH to /usr/local/freeswitch/python
before
restarting the mod_python-enabled freeswitch (via
modules.conf.xml)

# echo $PYTHONPATH
/usr/local/freeswitch/python

# grep mod_python \

Quote:

/usr/local/freeswitch/conf/autoload_configs/modules.conf.xml

<load module="mod_python"/>

# ls $PYTHONPATH
bar.py bar.pyc

# cat $PYTHONPATH/bar.py
stream.write("baz")

The relevant entry in conf/dialplan/default.xml:
<extension name="Test_Simple_Python">
<condition field="destination_number" expression="^1235
$">
<action application="set" data="foo=
${python(bar)}" />
<action application="bridge"
data="{group_confirm_file=vm-hello,group_confirm_key=4,call_timeout=60}
sofia/internal/1000,sofia/internal/1002" />
</condition>
</extension>

(The bridge action is only there because it seemed unhappy
unless it was
going to actually try to do something.)

The following output shows up in fs_cli when I dial 1235:

So I'm guessing something dumb on my part. But there are so
many dumb things I'm capable of doing... Smile

TIA,
Brian

Well, rescuing someone from the evils of javascript cleans so many years
off my time in purgatory that I couldn't possibly pass up the chance. Smile

But I'm still probably another week or two from qualifying as N00b. I
imagine I could probably handle transcoding javascript examples to
python if it's mostly just a syntax issue, which I imagine is most
cases.

I could start whacking one out if someone told me which examples to
steer away from because of javascript- or python-specific issues.

I would love to see the documentation for python flourish. I would
have chosen python for my recent development if I could have quickly
figured out how to use it. I chose the javascript route instead
because of all the examples on the wiki.

Thanks, you're hired! Smile

We definitely need Python users to step up and help with the docs.
There are only a few people so far who use Python so those who do use,
and want to see it flourish, need to work on the documentation.
Please start here:
http://wiki.freeswitch.org/wiki/Mod_python
Take it from there...
