[Confuse-devel] libconfuse help (several questions)

[Ademar de Souza Reis Jr.]

Hi.

[Please keep me in CC since I'm not subscribe to the list]

I'm trying to convert the config parser of one of my projects (sniffdet -
http://sniffdet.sf.net) to use libconfuse, but I'm having some problems (I'm
using libconfuse 2.0).

The new config system is basically finished (it works), but there are
some things that I just don't know if are possible to be done with libconfuse
or how to do them.

Here we go:

My config file has a syntax like:

"""
section1 {
        var = value
        ...
}

section2 {
        var = value
        ...
}
"""

1. In my config file, all sections are optional, but if, for ex.,
"sectionname" doesn't exist, I get an abort() when calling cfg_getsec(cfg,
"sectionname") because of a assertion at confuse.c:235. Is that a bug?  Or
Is there another way to discover if a section is present in the config file?
When reading the docs, I understood cfg_getsec() should return 0 in this
case, but it returns this value only if I didn't defined "sectionname" as
CFG_SEC() for the main cfg_opt_t structure, which I did of course
("sectionname" is valid, it's just optional).

Getting a segfault just because you commented out some parts of your
config file is really annoying (I was stuck in this problem for some
time) :)

2. Is there a callback for values different than int? The docs/example
mention the callback to set int values (CFG_INT_CB), but what I need is a
callback to parse string values.
Ex.: I have statements like:

foobar {
        fake_mac_address = {0x00, 0x00, 0x00, 0x00, 0x00, 0x01}
        fake_dest_ip_addr = "192.168.1.200"
}

And I would like to set a callback to check if the values have valid syntax
and are inside the valid range.

3: Actually, my config file has a ";" at the end of every statement. I know
that ";" has no strong semantic value in my case, but I would like to stay
with it anyway (to keep compatibility with my old config file - before
libconfuse). Is there a way to accept/enforce it? Confuse is interpreting it
as part of the value being assigned, returning "syntax error" (this is
really minor :).

4. Is the CVS at savannah.nongnu.org the main one? I'm asking this because
all files there have the last change from 7 weeks ago.

That's it. Any help will be really appreciated. Thanks!

(BTW, It's my first contact with libconfuse, so please forgive me if I'm
doing something stupid... :)
