Well, for plugins Nelly talks about, it is a nonsense to have a GLPi version in
their own versions.
For fusioninventory.... Well, it is generally compatible with one major version
of GLPi, so it makes sense.

You mean minor, right?
Anyways, I totally agree, plugins must not be broken between versions as far as
possible (even in major), but we cannot ensure we won't break anything with
minor changes on core's code :-/
What I had in mind is: what if we have to change something, say for security
reasons, that will break plugins? Well, that should not be something we'll see
each day :)

The point is to get a maximum of chances not to break plugins without plugins
can know, and prevent to upgrade plugins when it is not really needed (most of
the cases I've seen for the 9.1 upgrade so far).
I do not thing adding one or two lines of code will prevent contributions from
the user; that is not a complete rewrite of the whoe system ;)
Except for the min/max version, what would really affect plugins development;
what I propose is too find some guidelines and to document them; that last part
is very important; I'm not talking about rules everyone have to follow :)
In those guidelines, there will be some parts that are required (like adding
some functions in the setup.php) and some other that will be completely "good
practices"; up to the user/developer to do what he wants.
I'll have to work on some plugins; and I'll probably have to follow some
guidelines, so I can't get lost. I'd prefer to work on global guidelines than
editing a txt document on my part ;)
Ho, also... I've seen a plugin that declares a constant for its version, making
it quite easy to retrieve (let's say, for packaging for example?). So I also
propose (as a guideline!) to set a {PLUGINNAME}_VERSION constant.
I've begin to work on a developer documentation today; I had in mind to add a
plugins part on it to resume my proposals. If that is ok for you all, I'll work
a bit on it, and submit you the result before it's published.
Good evening,
