Postprocessing / custom attributes on MML parts

Postprocessing / custom attributes on MML parts

[Nuutti Kotivuori]

It appears that the postprocess-alist was removed quite a while ago.

How would one go about adding custom processing to mml parts nowadays?

Just something that would allow me to add:

<#part type="text/plain" disposition=inline process=foo>

And define somewhere what to either do with the process, argument - or
define somewhere an alist with foo pointing to a function run on the
part. Or something.

Hope you get my point.

Give me a good example about your custom processing.

Well, a simple one:

<#part type="text/plain" disposition=inline postprocess=ispell>

Ispell _this part only_ before sending. The same thing one would do
message-send-hook, but only for a specific part. And also that you
wouldn't have to do it always, but you could specify it by hand for
parts that you want checked.

Other things I'd want it for would be format=flowed generation through
the distinction between hard and soft newlines or other things. Then
more complex things would be to have for example a text/enriched part
that would be translated to both a text/enriched part and a text/plain
part is multipart/alternative, but that might be outside the scope of
such a simple post-processing function.

Actually, ispell should not be put here. mml-generate-mime will be
called more than once if there is "Gcc:" head or so.  Beside,
post-processing was called on the buffer containing generated mime,
therefore, the content could be some encoded text. You should still
use message-send-hook and find the certain part.

This is reasonable, but not an example for post-processing because of
the same reason stated above.  Anyway, I've added mml-tweak-type-alist
and mml-tweak-function-alist for this purpose. For example:

<#part type="text/plain" disposition=inline tweak=my-enrich-part>

and define a function my-enrich-part.  

This part of code is not tested. If you found bugs, please report them.
