0.8.26 Release

We are proud to release Elektra 0.8.26 with the new high-level API.

What is Elektra?

Elektra serves as a universal and secure framework to access configuration settings in a global, hierarchical key database. For more information, visit https://libelektra.org.

High-Level API

The new high-level API provides an easier way for applications to get started with Elektra.

To use Elektra in an application (including proper error handling) you now only need a few self-explanatory lines of code:

ElektraError * error = NULL;
Elektra * elektra = elektraOpen ("/sw/org/myapp/#0/current", NULL, &error);
if (elektra == NULL)
    printf ("An error occurred: %s", elektraErrorDescription (error));
    elektraErrorReset (&error);
    return -1;

// Once you have an instance of `Elektra` you simply call one of the typed `elektraGet*` functions to read a value:

kdb_long_t mylong = elektraGetLong (elektra, "mylong");
printf ("got long " ELEKTRA_LONG_F "\n", mylong);
const char * mystring = elektraGetString (elektra, "mystring");
printf ("got string %s\n", mystring);

elektraClose (elektra);

To run the application, the configuration should be specified, e.g., for mylong:

sudo kdb setmeta /sw/org/myapp/#0/current/mylong type long
sudo kdb setmeta /sw/org/myapp/#0/current/mylong default 5

In the getters/setters there is no need to convert types or to specify the base path /sw/org/myapp/#0/current, as the high-level API does that for you. The API supports the CORBA types already used by the plugins. The high-level API should also be used in combination with a specification (spec-mount). When used this way, the API is designed to be error and crash free while reading values. Writing values, can of course still produce errors.

Another advantage of the new API is, that it will be much easier to write bindings for other languages now, because only a few simple types and functions have to be mapped to provide the full functionality.

Take a look at the README for more information.

Because of the high-level API, we now have the new header files elektra.h and a folder elektra in Elektra's include directory. Furthermore, we install the library libelektra-highlevel.so and the pkgconfig file elektra-highlevel.pc for easier detection.

For an example on how to build an application using this API take a look at this.

A big thanks to Klemens Böswirth for making this possible. Also big thanks to Dominik Hofer, who did all the foundation work for this API.


The following section lists news about the plugins we updated in this release.






Enhanced the plugin to also check for concrete file or directory permissions such as rwx. For example, you can specify that a user can write to a certain directory or file which prevents applications of runtime failures once they try to access the given path (such as a log directory or file). Simply add check/path/user <user> and check/path/mode <modes> as specification (metadata) and be assured that you can safely set a path value to the key. A more detailed explanation can be found here (Michael Zronek)






The text below summarizes updates to the C (and C++)-based libraries of Elektra.


As always, the ABI and API of kdb.h is fully compatible, i.e. programs compiled against an older 0.8 version of Elektra will continue to work (ABI) and you will be able to recompile programs without errors (API).

We have two minor incompatible changes:

For details of the changes see below Core and Libease.
