hmm no as embryo is interpreted by the embryo vm... it's bytecode loaded at
runtime - i t has no idea of its original src. :) you could emit a signal and
use edje debugging to watch these signals like

emit("EDJEDEBUG", "something");

in your embryo script and have your code listen to "EDJEDEBUG" "*" messages and
print them out...

there isnt any such log/echo/printf function in edje atm. it'd be easy to maybe
add a DBG macro to edje_programs.c ... when a signal is emitted and use the
above emit as a debug...

then do:

export EINA_LOG_LEVELS=edje:4

and edje will give you debug log levels...

DBG<15145>:edje lib/edje/edje_program.c:1285 _edje_emit_handle() EDJE EMIT:
(0x5 5604e48afb0) signal: "elm,action,hide,vbar" source: "elm"

like that... any emits. so grep/filter for your emit log... :) i'll enable the
DBG in git now.. but his needs a new efl release. commit is here:

Re: [E-devel] Debugging edc at runtime is possible?

U can use printf() in the program script for debugging.

ie)

programs {
   ..
   script {
printf("call %d\n", xxx);
   }
}

the printf logs will be printed ony when app launched with EINA_LOG_LEVEL=3 or 
more.

it's possible to do this by breaking conditionally on the _edje_program_run 
function based on a program's attributes

this is also possible by breaking on edje/embryo/edje_embryo functions and 
stepping through them

This is an interesting idea. I don't know if it could be doable
actually as program are run related to time. Any debugging would
likely affect that.

Agreed, I don't see a way to do step by step debugging of an edc. Will
have to think about it.

> If it is impossible, how about log function for edc? (only for debug)

Once upon a time, there was a lot of log generated in the form of edje
signal. They were removed as they impacted speed to much. Today, we
have evlog, it may be worse experimenting with it and see if we can
log events with it somehow. Alternative possibility would be to add an
eo event on edje object for debug. Once someone register for that
event, we would trigger that event for every state we want to debug.
Between evlog and eo event tracing, I don't know which one could work
best. You would have to experiment !

Have fun !
