Re: [Configobj-develop] Getting those nice validation error messages out

I ended up with something like this:

# Check / processing functions for options
def check_result(sct, res, err_strs=3D[], levels=3D['[root]']):
    if res is True: return
    if res is False: res =3D dict(zip(sct.keys(), [res]*len(sct)))

    for (k, v) in sct.items():
        if res[k] is True: continue
        if isinstance(v, dict):
            # Go down one level
            levels.append(k)
            check_result(v, res[k], err_strs, levels)
            continue
        try:
            vtor.check(sct.configspec[k], v)
        except validate.ValidateError, err:
            err_strs.append("%s, %s: %s" % (", ".join(levels), k, err))

    # Go up one level
    if levels: levels.pop()

    return err_strs

# Run checks
val_res =3D opts.validate(vtor)
if val_res is not True:
    print "\n".join(check_result(opts, val_res))

I hope this is efficient, I am rather new to python. Of course I was
wondering if I was missing some way of avoiding redoing the error
checks, but it sounds like I haven't, and this works fine for me.  I
wonder if there is any interest in a patch to the configobj.py
funciton, on the lines of:

def validate(self, validator, section=3DNone, error_strs=3D[], levels=3D['b=
ase'])

then

val_res =3D opts.validate(vtor, errror_strs =3D my_list)?

Thanks a lot.
