[Lcd4linux-devel] Question regarding evaluator and reuse of return values

[Dan F. <tem...@ya...>]

I've been pondering on this for a while now, maybe I'm daft and can't
see the obvious solution...

Ok, i got this plugin that communicates with a remote process, lets say
eMule as an example.
It is threaded and it returns a set of values every other minute.

How do i make use of these values in multiple widgets, i.e how to i use
them i one text only widget e.g "Upload 6KB, Download 10KB" and two bar
widgets at the same time without having to duplicate the "information 
retrieval" thread?

The only solution i can find is to let the widget that actually runs the
thread to be "named" and that other widgets can refer its data by that
name (or hash if you prefer) as a reference.

This is something i can easily implement since I've implemented the 
threading of python plugins in python :) 
This was much easier for me to implement and it makes the python plugin
development process much more convenient because python plugins can now
be developed, debugged and tested in pure python - threading and all.

Anyhow, this is how a config file could look like:

Widget EMULE {
    # This widget does not have to be visible
    class 'Text'
    # module = 'emule'
    # function = 'getStats'
    # hash/keyword/identifier/whatever = 'emule_hash'
    # periodicity = 1 minute (60000)
    expression  python::threaded_exec('emule', 'getStats', 'emule_hash',
60000)
    prefix 'eMule '
    width 22
    align 'M'
    update 30000
}

Widget EMULE_TXT {
    class 'Txt'
    expression  python::get_value('emule_hash', 'most_popular_upload')
    length 10
    direction 'E'
    update 30000
}

Widget EMULE_BAR {
    class 'Bar'
    expression  python::get_value('emule_hash',
'download_as_percentage')
    expression2 python::get_value('emule_hash', 'upload_as_percentage')
    length 10
    direction 'E'
    update 30000
}

i.e Widget EMULE_BAR and EMULE_TXT displays data retrieved by widget
EMULE.

Is this something you guys could live with (at least for the python
section of lcd4linux, since does not affect anything else than
plugin_python.c)? Or am i missing something?
Maybe something like this is already exists?
