The code is already duplicated once, and I want to add a third
configuration item that is also a list.
---

Mainly I am curious if people think using macros to declare these
"getters" and "setters" makes the code less maintainable.

Deduplicating this code seems like a great idea, but I don't think
macros are the way to do it; especially not one that expands to an
important top-level construct like a function definition.

What about something like

const char **
notmuch_config_get_user_other_email (notmuch_config_t *config,
                                     size_t *length)
{
    return _config_get_list (config, "user", "other_email", 
                             &config->user_other_email, length);
}

where config->user_other_email is a, say, struct _notmuch_config_list
that combines together the cached string list and length?
_config_get_list would look a lot like what you have now, but outlist
would be a struct _notmuch_config_list* instead of a const char*** and
it would always set *length (in addition to setting it in the cached
value if necessary).

Set could be similarly simple

void
notmuch_config_set_user_other_email (notmuch_config_t *config,
                                     const char *other_email[],
                                     size_t length)
{
    _config_set_list (config, "user", "other_email", &config->user_other_email,
                      other_email, length);
}

Two new internal routines are created _config_get_list and
_config_set_list; the notmuch_config_get_* functions that deal with
lists are simply wrappers for these functions.

Looks good to me.  Some comments below.

It seems weird that the function both takes list as an output parameter
and returns it.  Having two length parameters which are set to the same
value is confusing as well.  I understand that it is done to make getter
functions smaller.  So perhaps it is ok.

Please move variable declarations inside the if (!*outlist) and if
(inlist) blocks.  (I saw other code in notmuch that does it, so it must
be ok.)

I would prefer to have this on separate lines.

This should be part of a separate patch which adds the logging feature,
I guess.

Updated version pushed. I'm not completely happy with _config_get_list's
weird API, but I don't have a better idea now.

Much cleaner!

However... this would preferrably have been preceded by tests.

Patch follows.

This doesn't seem like an especially helpful commit
message. Editorializing is ok, I guess, but maybe keep it below the

You're right.  The message I was trying to convey (quite tersely),
was that these tests were written in response to commit 1df71b55
(and should probably be retroactively ran on 1df71b55~1).

I realize now that it could potentially be wrongly interpreted as
criticism of sorts, which of course wasn't my intention.

Anyways, I ran the tests on both 1df71b55~1 and 1df71b55, and
-as expected- everything checks out fine.

Amended patch follows.

Full test coverage for getting, setting and removing options in
notmuch(1)'s config file ($NOTMUCH_CONFIG or $HOME/.notmuch-config).

Please *do* take note of the FIXME in the last test!

I'm not sure how portable it is, but maybe dnsdomainname would at least
have better failure modes.

I also wondered about using getent instead of grep.

Hmmm, `dnsdomainname' returns "(none)" here;  Does it work for you?

Running `domainname' instead seems to do the right thing though...


It would probably be safest to simply mirror how it's done @
notmuch-config.c:313, but that seems rather excessive.

Agreed, much safer;  `grep' might return multiple results.

How about this? :

  #+begin_src sh
    fallback_name="$(getent passwd ${USER} | cut -d ":" -f 5 | cut -d "," -f 1)"
    test -n "${EMAIL}" \
        && fallback_email="${EMAIL}" \
        || fallback_email="${USER}@$(hostname).$(domainname)"
  #+end_src


Peace

I make no claims to have "correctly" configured this machine on my home
network, but here it is the opposite.  The docs refer to NIS for
domainname, which I guess is not _that_ common for home networks (or at
all anymore?).

Same here :)

$ grep hosts /etc/nsswitch.conf
hosts: files dns

I guess that's a no.

Perhaps others could chime in?
