David Baelde updated LS-405:
----------------------------
Priority: Minor (was: Blocker)
> Services as methods
> -------------------
>
> Key: LS-405
> URL: http://dev.sourcefabric.org/browse/LS-405
> Project: Liquidsoap
> Issue Type: New Feature
> Components: Liquidsoap
> Reporter: David Baelde
> Assignee: David Baelde
>
> I'm considering an object-oriented extension of our scripting language that
> would allow a nice integration of services (server commands) as methods. It
> would make it possible for users to redefine methods, define their own. Also,
> it would bring some structure to services, ensuring that they are printed in
> a uniform way. Finally, it brings recursivity (through self) that was needed
> in some cases:
> {{{
> def live =
> # dummy init, an option type would be nice...
> o = ref blank()
> extend input.harbor("/mount") with
> method on_connect() =
> o := output.file(%vorbis,"backup.ogg",self)
> end
> method on_disconnect() =
> source.shutdown(!o)
> end
> end
> end
> }}}
> It doesn't seem too hard to do (except for migrating all existing server
> code) but I need to make sure how to handle the recursive types that can
> arise.
> There are a couple questions:
> * Do we still reference sources by their ID in the server? It's not always
> possible to reference them through variable names.
> * How much of the API do we change? Is (!o)#shutdown preferable to
> source.shutdown(!o)? Should all event handlers become methods?
> * How will we print those huge types?
