geneet

Generator for EFL's pickler/unpickler library, EET

Introduction

Given a simple description about a data structure, geneet will generate the C source code so it can be serialized/deserialized by using the EET library.

Even though it is possible to write code to use EET by hand, it can be pretty boring and error-prone. Geneet's structure syntax is as simple as it gets and, in the future, will be possible to use it for other languages as well.

Geneet supports currently:

Fundamental types

str
int, uint
float, double

Enumeration
Images
Lists
Hashes

Generated code can:

Initialize/shutdown the EET descriptor structures
Allocate/free a structure
Load/save a structure to a file

Geneet Syntax

%Structure_Name {
  %field_name : %type [%arguments];
}

%Structure_Name and %field_name can be any valid C identifier
%type can be one of

str
int
uint
float
double
list
hash
enum

%arguments varies depending on the %type used; it can be either optional, or mandatory, according to the following table:
Type Optional Argument
str
Yes
default "Default value"
list
No
of %Structure_Name
hash
No
of %Structure_Name by %field_name
enum
No
of %name1, %name2, ..., %nameN

Type	Optional	Argument
str	Yes	default "Default value"
list	No	of %Structure_Name
hash	No	of %Structure_Name by %field_name
enum	No	of %name1, %name2, ..., %nameN

Usage

Usage is pretty simple; just call geneet with a .geneet file with the structure definition you want. Refer to included .geneet files for examples. Running:

	$ geneet phonebook.geneet

Will create phonebook.c and phonebook.h.
