Since version 0.8.15 libelektra is split into following libraries:

Overview of Libraries

Loader

loader contains source files that implement the plugin loader functionality. The files are linked to libelektra.

Libease

libelektra-ease.so

libease contains data-structure operations on top of libcore which do not depend on internals. Applications and plugins can choose to not link against it if they want to stay minimal. Its main goal is to make programming with Elektra easier if some extra kB are not an issue.

Libplugin

libelektra-plugin.so

libplugin contains elektraPlugin* symbols and plugins should link against it.

Libpluginprocess

libelektra-pluginprocess.so

libpluginprocess contains functions aiding in executing plugins in a separate process and communicating with those child processes. This child process is forked from Elektra's main process each time such plugin is used and gets closed again afterwards. It uses a simple communication protocol based on a KeySet that gets serialized through a pipe via the dump plugin to orchestrate the processes.

This is useful for plugins which cause memory leaks to be isolated in an own process. Furthermore this is useful for runtimes or libraries that cannot be reinitialized in the same process after they have been used.

Libproposal

libelektra-proposal.so

libproposal contains functions that are proposed for libcore. Depends on internas of libcore and as such must always fit to the exact same version.

Libmeta

libelektra-meta.so

libmeta contains metadata operations as described in METADATA.ini. Will be code-generated in the future, so methods should be mechanical reflections of the contents in METADATA.ini.

Libcore

libelektra-core.so
<kdbhelper.h>
<kdb.h> (key* and ks*)

Contains the fundamental data-structures every participant of Elektra needs to link against. It should be the only part that access the internal data structures.

Libtools

libtools is a high-level C++ shared-code for tools. It includes:

plugin interface
backend interface
3-way merge

Utility

libutility provides utility functions to be used in plugins.

Libinvoke

libelektra-invoke.so

libinvoke provides a simple API allowing us to call functions exported by plugins.

IO

libelektra-io.so

io provides the common API for using asynchronous I/O bindings.

Notification

libelektra-notification.so

notification provides the notification API. Usage examples:

Globbing

libelektra-globbing.so

globbing provides globbing functionality for Elektra.

The supported syntax is a superset of the syntax used by glob(7). The following extensions are supported:

#, when used as /#/ (or /#" at the end of the pattern), matches a valid array item
_ is the exact opposite; it matches anything but a valid array item
if the pattern ends with /__, matching key names may contain arbitrary suffixes
