What version of xulrunner SDK for compiling Javascript XPCOM components?

[moonbat]

I"m following this guide on how to create a Javascript XPCOM component, and it describes compiling an IDL using xpidl from the xulrunner sdk. I downloaded the sdk from here, version 41.0.2 but it has a python script called xpidl.py, and that gives an error on running -

Code: Select all

 except IDLError, e:
           ^^^^^^^^^^^
SyntaxError: multiple exception types must be parenthesized

Is there a specific older version of the SDK that's compatible with Pale Moon - or is this a Python 2 vs 3 related problem?

That's a python2/3 problem

Code: Select all

    except IDLError, e:

is python 2 syntax. python3 expects

Code: Select all

    except IDLError as e:

You'd probably be better getting hold of a python2 interpreter, as you could run across all sorts of fun doing the upconversion.

Good idea, I already have python2 so I'll try using that.

No dice
It won't parse the commandline arguments as per the documentation (section on compiling the typelib).

Code: Select all

python2 xpidl.py -m typelib -w -v -I ~/Documents/code/xulrunner-sdk/idl/ -e ~/Documents/code/pmplusobserver.idl ~/Documents/code/pmplusobserver.xpt
Parsing -m
Traceback (most recent call last):
  File "xpidl.py", line 1427, in <module>
    p.parse(open(f).read(), filename=f)
IOError: [Errno 2] No such file or directory: '-m'

I looked at the code and there's no way that command line they give you is right. Although to be fair, it suggest's you should be running xpidl.exe, not xpidl.py. I can't see the former anywhere in my download. The latter doesn't accept anything other than a list of idl files to parse
