The embryo script works well but the lua script didn't. The message custom
is never print in stdout.
If you add in lua_script_only: 1; before the script it works. I've
attached a patch that uses the lua_State for the collection, and
allows for message sending without script_only. It seems to work here
but perhaps Hanspeter could comment on its correctness.
Never mind, it allows you to call the function but not to do anything
useful inside it.

This concerns Ticket #109: Add Lua support for Edje
It adds Lua as scripting facility to Edje, letting Embryo untouched.
It should be easier to use and be more flexible than Embryo, imho ;-)
---
The patch
---
Lua 5.1 is used in sandboxed mode. Lua byte code is not
platform/architecture independent, Lua code is saved as text in the Edje
container and parsed at load time, therefore.
The patch goes in two directions
1) Analogous to Embryo for scripting logic, messaging and custom states.
The same things are implemented as in Embryo:
- messaging from and to C
- manual creation of timers, animators, pollers for custom events /
animations
- manual manipulation of Edje parts by means of the public
edje_object_part_* and internal functions and custom states
- those routines are actually implemented as Lua bindings to
functions in Edje.h and Ecore.h
- the implementation is done in an object oriented way, so that the
interface gives the feel of an object description language, pretty
similar to EDC itself
- combining custom states and custom animators allows for fancy
animations and transitions, e.g circular/spline translations or
complex/conditional transitions, etc.
- this is just the same as Embryo does, but implemented in Lua, so
nothing new here, actually
2) Dynamic object creation and manipulation
- this interface stems from the 'script_only' objects in Edje. Those
objects are a kind of scriptable Edje counterparts to Evas_Smart
objects. The infrastructure for Embryo is already there, but has
never been used
- I added this in Lua and added some first bindings to experiment
with
- I thought it would be useful to allow for a limited dynamic
creation of ui parts
- We can create instances of groups from within the same Edje
container and use them just like the main Edje object as stated in
1)
- And there are some stand-alone bindings to dynamically create
Evas_Image, Evas_Table, Evas_Line, Evas_Polygon as examples
- this may be useful to decouple the program from the ui even more,
to be able to do things that have to be done in the program itself
atm, but actually belong to the user interface, but need dynamic
creation of objects or complex interactions
- those objects are manipulated manually with Lua bindings to the
corresponding edje_object_* and evas_object_* functions

Discussion points

Both stuff in 1) 2) is functioning, but needs testing, feedback,
improvements, ...
Stuff in 1) can already fully replace Embryo scripting with Lua
scripting. There still is space for improvements/additions, though.
Of the stuff in 2), I think it may only make sense to add the dynamic
creation of groups defined in the same Edje container. Dynamic creation
of other Evas_Objects makes not much sense, as most of them can already
be used as Edje parts and be manipulated with custom states (apart from
polygons and lines) and it would make the whole theming potentially more
programing-like and much more susceptible for errors, etc.
Would this be useful, or drop it all?
The scripting should be there just for logic, conditionals, custom
states and animations, not for a whole dynamic canvas, imho.
There is a patch around with EXTERNAL Edje parts. Seems to be a better,
faster, more secure way to extend Edje with custom objects
