but it could be much much much cleaner/better so i started a minimalist redo.
it's temporarily enabled right now. will disable soon to do in the background.

Sometimes you want to catch an action like "clicked" from elm/button
or "mouse,clicked,1" from a regular part and want to set a property
like "play" on some object. In this case there is no source property
to copy, so setting the destination makes sense. This was possible
with Embryo, and now it is with regular "program".
Sample EDC:
{{{
// test.edc, compile with edje_cc and run with edje_player
externals {
external: "elm";
}
collections {
group { name: "main";
parts {
part { name: "bg"; type: RECT;
description { state: "default" 0.0;
color: 255 255 255 255;
}
}
part { name: "button"; type: EXTERNAL;
source: "elm/button";
description { state: "default" 0.0;
rel2.relative: 1.0 0.5;
}
}
part { name: "display"; type: TEXT;
description { state: "default" 0.0;
color: 0 128 0 255;
rel1.relative: 0.0 0.5;
rel2.relative: 0.5 1.0;
text { font: "Sans"; size: 16; }
}
}
part { name: "entry"; type: EXTERNAL;
source: "elm/scrolled_entry";
description { state: "default" 0.0;
rel1.relative: 0.5 0.5;
params.bool: "editable" 0;
}
}
programs {
program {
signal: "clicked";
source: "button";
action: PARAM_SET "display" "text" "hello world!";
}
program {
signal: "clicked";
source: "button";
action: PARAM_SET "entry" "text" "bla!";
}
}
}
}
}
}}}

Choices are useful to represent enumerations and restricted set of
elements to user. Usually this is displayed in hoversel/comboboxes.

Edje got a new program action called PARAM_COPY in the form:
action: PARAM_COPY "src_part" "src_param" "dst_part" "dst_param";
This will copy the parameter "src_param" from part "src_part" to
parameter "dst_param" of part "dst_part".
So far so good, why the "crazy" in the first line? Because this also:
* do type conversion!
* set properties of native parts, not just EXTERNAL!
The type conversion allows one to get an integer and display that in a
text property, or get an string and convert into a float.
The set of native parts is quite simple, basically a map of Edje.h
edje_object_part_*_set(). With that one can set the string to be used
by a TEXT, or set drag page/step/size/value! (page/step increments are
not supported at the moment, if it is worth, they may be supported in
future).
Sample EDC:
{{{
// test.edc, compile with edje_cc and run with edje_player
externals {
external: "elm";
}
collections {
group { name: "main";
parts {
part { name: "bg"; type: RECT;
description { state: "default" 0.0;
color: 255 255 255 255;
}
}
part { name: "entry"; type: EXTERNAL;
source: "elm/scrolled_entry";
description { state: "default" 0.0;
rel2.relative: 1.0 0.5;
}
}
part { name: "display"; type: TEXT;
description { state: "default" 0.0;
color: 0 128 0 255;
rel1.relative: 0.0 0.5;
text { font: "Sans"; size: 16; }
}
}
programs {
program {
signal: "changed";
source: "entry";
action: PARAM_COPY "entry" "text" "display" "text";
}
}
}
}
}
}}}

I'm now introducing a couple of goodies to make externals more useful,
they are:
* add: extra parameter with the part name. This may be used by
external objects to emit signals in the name of that part.
* param_set/param_get: set parameters at runtime, given their names
and types. This avoids requiring users to get the actual object and
call methods. This abstraction is also good because it let one uses
Elementary without even linking to it ;-) (this have limits, like
complex types are not supported). Right now this is just exposed
to C, but goal is to have it exposed in Embryo and Lua as well.
* translate: new method to translate previously strings that are
specified statically, such as the parameters names.
Four new functions got added to the Edje API:
* edje_object_part_external_object_get() so we don't have to abuse
edje_object_part_swallow_get()
* edje_object_part_external_param_set() and
edje_object_part_external_param_get() that call the external type's
functions.
* edje_external_param_type_str() to convert types to string and
provide nicer debugs :-)
TODO:
* expose external_param_set()/external_param_get() to Embryo and Lua.
