 * Simple Elementary example illustrating how to use elementary_codegen.
3
 *
4
 * elementary_codegen is a tool that generates code to acessing the
5
 * parts and programs with the keyword "api" of a specified
6
 * group. This tool make easier working with edje avoiding common
7
 * misspelling errors when acessing the parts and/or programs.
8
 *
9
 * To use the elementary_codegen:
10
 * elementary_codegen --prefix <myapp_myobj> <input.edj> <a_group> <source.c> <header.h>
11
 *
12
 * In the case of this example:
13
 * elementary_codegen --prefix=codegen_example codegen_example.edj \
14
 * elm/example/mylayout/default codegen_example_generated.c codegen_example_generated.h
15
 *
16
 * @verbatim
17
 * edje_cc codegen_example.edc && elementary_codegen --prefix=codegen_example \
18
 * codegen_example.edj elm/example/mylayout/default codegen_example_generated.c \
19
 * codegen_example_generated.h
20
 * gcc -c codegen_example_generated.c `pkg-config --libs --cflags ecore-evas edje elementary`
21
 * gcc -o codegen_example codegen_example_generated.o \
22
 * codegen_example.c `pkg-config --libs --cflags ecore-evas edje elementary`
23
 * @endverbatim
