[Q] working with nnoo

[Q] working with nnoo

[Didier Verna]

        Hi!

There are several things I don't understand very well about nnoo. Suppose I'm
writing an nnml-like backend nnfoo.

1/ Can I inherit the nnml-open-server function, for example ? The problem I
see is in calls like "(nnoo-change-server 'nnml server defs)", especially the
symbol part ('nnml).

2/ I probably also have to rewrite all function that contain strings
containing "nnml", which is unfortunate.

3/ Also, consider the following case: I have to write my own
nnfoo-request-expire-articles, the body of which starts with a call to
nnfoo-possibly-change-directory which I could theoretically inherit from nnml.

As far as I can understand it, this won't work because the directory variable
that will be set would really be nnml-directory, and thus all references to
nnfoo-directory in the body of nnfoo-request-expire-articles would be wrong,
right ?


        Thanks

I think that defvoo arranges for nnfoo-directory and nnml-directory to
have the same values, or something.

You have to explicitly call nnoo-change-server to sync nnfoo variables
to nnml variables.

You may use (nnoo-parent-function 'nnfoo 'nnml-the-function ...),
which calls nnoo-change-server.

nnml-possibly-change-directory is not inheritable.

nnoo-parent-function takes care it.
