Before trying to implement anything I decided to send a mail to the list
to ask people's opinion.

What's the problem?
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Notmuch isn't very configurable.

How can Lua integration solve this?
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Here are initial thoughts on how to integrate Lua with notmuch.
Any comments appreciated.

1. Configuration file:
The configuration file can be a Lua script that allows more dynamic
configuration. Here's an example:

# notmuch configuration file:
config =3D {}
config.dbpath =3D "/path/to/maildir"
config.exclude =3D function (maildir)
    return not string.match(maildir, ".*Trash.*")
    end
=2E..

2. Hooks:
This is a feature I really miss having switched from sup.
There can be many hooks, a hook that formats search output,
a hook that is called before adding messages to the database which may
be used to add initial tags depending on headers etc.

Why Lua?
=3D=3D=3D=3D=3D=3D=3D=3D
Lua has many advantages over other scripting languages when it comes to
integration with a C program. It has a very clean and easy C API, the
overhead of running Lua scripts is not noticable among other things.
