configobj-develop — Support and development of ConfigObj

[Configobj-develop] ConfigObj 4.4.0

[Michael F. <fuz...@vo...>]

Hello all,

ConfigObj 4.4.0 has just been released. Eggs for Python 2.4 and Python 
2.5 are available from the cheeseshop.

[Configobj-develop] ConfigObj 4.4.0 and Validate 0.2.3

[<fuz...@vo...>]

{ran_emo} Updated versions of both `ConfigObj <http://www.voidspace.org.uk/python/configobj.html>`_ and `Validate <http://www.voidspace.org.uk/python/validate.html>`_ are now available.

* `ConfigObj 4.4.0 <http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=configobj-4.4.0.zip>`_
* `Validate 0.2.3 <http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=validate.py>`_

**ConfigObj** is a Python module for the simple reading and writing of config files. It has many features, whilst remaining easy to use.

With the assistance of **Validate** it can validate a config file against a specification, and convert members to the expected type.

Thanks to Nicola Larosa who implemented most of the fixes in this release.

.. raw:: html

    {title;What is New in ConfigObj 4.4.0?}

* Made the import of compiler conditional so that ConfigObj can be used with IronPython.

* Fix for Python 2.5 compatibilities.

* String interpolation will now check the current section before checking DEFAULT sections. Based on a patch by Robin Munn.

* Added Template-style interpolation, with tests, based on a patch by Robin Munn.

* Allowed arbitrary indentation in the ``indent_type`` parameter.

* Fixed Sourceforge bug #1523975 by adding the missing ``self``


.. raw:: html

    {title;What is New in Validate 0.2.3?}

Fixed validate doc to talk of boolean instead of bool; changed the ``is_bool`` function to ``is_boolean`` (Sourceforge bug #1531525).

Ok, I'll look at getting a new release with 2.5 support and Nicola's new 
features done over the weekend.

Seconded (or re-seconded? since I was the original poster). I first
noticed the missing 2.5 eggs problem because of
http://docs.turbogears.org/1.0/Python2.5Support too. I'd really like
to see TurboGears with complete 2.5 ability, and that means bringing
ConfigObj up to speed.

Pretty please? :-)

if that's the case then let me cry for 2.5 eggs too :D

ConfigObj and ruledispatch are the only ones missing, and since pyrex is out
all we need for rule dispatch is see if it compiles

Hello Robin,

I think that to use ConfigObj with Python 2.5 you will need the version 
from subversion anyway. There is a rogue '__future__' important which is 
in the right place in subversion, but in the wrong place in the latest 
release.

I should probably do a new release because Nicola has made several good 
changes since the last release. I've been very distracted recently though.

As for eggs... well seeing that installing ConfigObj is a difficult as 
dropping one file somewhere on your path I never got round to doing 
that. I only uploaded the 2.4 eggs to stop the turbogears folk crying. ;-)

As setuptools seems to be maturing nicely (and is very nice to use) I 
should probably fix this. I'll be going to a setuptools talk at PyCon, 
so hopefully this will motivate me to sort it out.

All the best,

[Configobj-develop] Can't easy_install ConfigObj for Python 2.5

[Robin M. <rob...@gm...>]

"easy_install ConfigObj" doesn't work if you're using Python 2.5.
There's no .egg for 2.5 linked from the
http://www.python.org/pypi/ConfigObj/ page, so setuptools downloads
the source and tries to run "setup.py -q bdist_egg --dist-dir
/tmp/easy_install-kjBHsO/egg-dist-tmp-wnCMdZ" instead. But that fails
with TypeError: "compile() expected string without null bytes". When I
run the same setup.py command by hand from inside the configobj-4.3.2
directory, I get:

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'bdist_egg'

What would it take to get ConfigObj using a setup.py that's setuptools-aware?

Ah.... I *thought* there was code in there which tracked whether the 
original was terminated with a newline and adding one if necessary.

However as I can't see that code I must have been hallucinating. :-)

I guess that's a bug and should be fixed sometime.

[Configobj-develop] ConfigObj.write() produces dangling last line

[Salazar, M. <mar...@sp...>]

I observed the files created by ConfigObj.write() were missing the
newline character on the last line. Sure enough examination of the code
reveals something like:

=3D=3D=3D

Output =3D (expressionReturningANewlineChar).join(out)

.

.

.

Outfile.write(Output)

=3D=3D=3D

which will leave off the final newline. Am I missing something?

Re: [Configobj-develop] some enhancements

[Jack K. <kj...@gm...>]

Hi Nicola and all,

thanks for your time in going through my proposed features.
Although all of them were added because I felt convenient to have them while
writing my own configuration
files, I agree that not every one will like or need the same features. I
shared my work with the hope that someone might find it useful; if it's
integrated back to the project, that's great; if it's not accepted, I'm
already grateful to have had the chance on improving the project and sharing
and expressing my contributions!

Thank you all, and happy new year!
Jack

Sorry for the delay, Jack. At least we got to it within the month (and the
year). :-)

We talked about your proposed feature. The outcome is still open on a
couple of them, but here goes.


> It includes the following changes:

I don't like it. It doesn't seem very useful in this case, and pickling is
fairly unmaintainable and insecure, I don't ever use it. But Michael has a
more positive opinion about it, let's see how it pans out.

We don't see use specific use cases for this, so we're going to reject it.

I think it may be useful, we're still looking into this.

This kind of syntactic sugar does not seem very useful, so it's not going
in either.

This is already in, as part of an earlier enhancement.

As above, we don't see use specific use cases for this, so we're going to
drop it too.


In summary, one feature is already in, two are still in discussion, and
three are not going in.


Thanks for your contribution, and sorry for forcing you to keep maintaining
you own fork; alas, ConfigObj is already fairly bloated, and we don't feel
like keeping on bloating it without fairly good reasons.

[Configobj-develop] Some more work on ConfigObj

[Nicola L. <ni...@te...>]

Some more effort spent on ConfigObj.

Fixed validate doc to talk of ``boolean`` instead of ``bool``; changed the
``is_bool`` function to ``is_boolean`` (Sourceforge bug #1531525). Thanks
to the reporter for this one.

Added a missing ``self.`` in the ``_handle_comment`` method and a related
test, per Sourceforge bug #1523975. Thanks to the reporter for this one too.

Allowed arbitrary indentation in the ``indent_type`` parameter, removed the
``NUM_INDENT_SPACES`` and ``MAX_INTERPOL_DEPTH`` (a leftover) constants,
added indentation tests (including another docutils workaround, sigh),
updated the documentation. Thanks for this one go to Jorge Vargas, even if
I ended up not using his patch that added a new ``indent_size`` parameter.

The ':' keyword/value separator character is not allowed by ConfigObj, only
the '=' one is.

The following code uses the SVN repo, the interpolation logic changed from
v.4.3.2 .

>>> from pythonutils import configobj
>>> cfgList = ['[object]', 'field1 = test test test %(uid)s']
>>> cfg = configobj.ConfigObj(cfgList, interpolation = 'ConfigParser')
>>> cfg['object']['field1']
Traceback (most recent call last):

You need to create the DEFAULT section first.

Try :

config['DEFAULT'] = {'uid': 'user'}

> config['uid'] = 'user' (MissingInterpolationOption). 

ConfigObj uses the DEFAULT section or (current SVN only) the current 
section for interpolation values.

As mentioned before, in order to use the DEFAULT section it must exist.

[Configobj-develop] Setting values for interpolation at runtime

[Michael H. <lis...@mi...>]

I have severe problems getting interpolation work for me. I have a 
config file with e.g. the following content:

| [object]
| field1: test test test %(uid)s

The uid-value is not defined in the config file but shall be set on
runtime. I can't figure out how to set the value, i always end up 
with 'MissingInterpolationOption' or other errors (e.g. KeyError).

I tried for example config['DEFAULT']['uid'] = 'user' (KeyError),
config['uid'] = 'user' (MissingInterpolationOption). I'm sure i
make a simple mistake, but i can't figure it out. Some help would
be appreciated.


Regards
Michael

Thanks to you, Jack, I'll be working on them.

Ideally, each new feature should be self-contained in a single
unified-style patch (as output by the "diff -u" command), and accompanied
by relevant patches to configobj_test.py and configobj.txt, for tests and
docs. That would minimize our work, and considerably quicken the path to
inclusion in the codebase.

But ehi, I can't really complain. Keep those contributions coming! :-)

[Configobj-develop] some enhancements

[Jack K. <kj...@gm...>]

Hi all,

attached is my version of configobj.py modified from configobj 4.3.2. It
includes the following changes:

- pickling support
- list interpolation. For example:
    k = 1,2,3
    h = %(k)s
    g = interpolate %(k)s into a string
    f = interpolate, %(k)s, into, a, list
    l = %(k)s,
 can be interpreted as the following:
    k = 1,2,3
    h = "1,2,3"
    g = "interpolate 1, 2, 3 into a string"
    f = interpolate, 1, 2, 3, into, a, list
    l = 1, 2, 3
- environment variable interpolation. Eg, %(PATH)e  gives the value of the
PATH environment variable
- "section path interpolation". Example:
  %(a/b/c/k)p interpolates the value of key, k, of subsection c of
subsection b of subsection a of the current section.
  .. and . and absolute path can be used as well:
  eg,  %(../a/b/c/k)p      %(/a/b/c/k)p
  '/' can be escaped with \/  and . can be escaped with \.

- double % escapes interpolation, ie. %%(abc)s gives %(abc)s literally
- added two methods, lookup and fetch, to Section, to search a key upward
the tree.

The changes should be clear if you compare the configobj.py 4.3.2 with the
modified version.
I hope these features might be useful to others as well.

Thanks all!
Jack

Both patches are now included in the SVN repo. Thanks again for them,
Robin, and sorry for not having come round to them sooner.


ConfigObj now supports both ConfigParser-style and Template-style
interpolation, with a more consistent search strategy (see docs).


> I've also attached the sample .ini file I used for testing, called
> "deepsearch.ini", so you can verify for yourself that the code works.

I added new tests to configobj_test.py based on this one and on the other
.ini file.


A new release containing these changes will have to wait for the further
changes that are coming up in the pipeline. In the meantime, the SVN repo
is reliable and tested. Please let us know any problems these changes may
cause to your config files.

[Configobj-develop] Commi to Ordered Dictionary

[Nicola L. <ni...@te...>]

I started by refreshing the Ordered Dictionary (part of the PythonUtils, as
ConfigObj). I added some stuff proposed by Tim Wegener, and made some
cleanup to the code and the docs.

Those not willing to wait for the 0.2.2 official Ordered Dictionary release
may get the files from Subversion.

And now we return you to the regular ConfigObj programming.

[Configobj-develop] Spring cleanup

[Nicola L. <ni...@te...>]

As noted in our esteemed host's blog, I'm going to do some spring cleanup
of open issues on ConfigObj. (It's spring, at least in the southern
hemisphere, right?)

Expect several replies to old threads in the next days.

Oh, and don't pay too much attention to the grim signature behind the
curt... I mean, below.

Re: [Configobj-develop] Making ConfigObj pickle-able

[Fuzzyman <fuz...@vo...>]

Hello Jack,

Sorry for the delay in getting to this. Work on Movable Python (etc) has
taken longer than expected.

Thanks for the code. I'll try and get it integrated into an official
release as soon as possible.

All the best,
