Elektra 0.10.0
|
Only libelektra-core
is supposed to access private data, but this contradicts the goal to keep the library minimal. kdbprivate.h
was too generic, it contained many other parts next to the struct definitions of Key/KeySet.
mmapstorage
need access to private data structure.mmapstorage
should still work) must use the same struct definitions of Key/KeySet.Also allow libelektra-extra
(and maybe other explicitly documented libraries) to access private Key/KeySet. Put struct definitions of Key/KeySet in a separate header file, which gets included by parts that need it.
All currently planned libraries and their respective API prefixes are listed in the Notes below.
libelektra-core
libelektra-core
: The core minimal API of Elektra. Defines what ElektraKey
and ElektraKeyset
are, and contains the minimal API for manipulating them.
Prefixes: elektraKey*
and elektraKeyset*
libelektra-kdb
: The main API for interfacing with the KDB.
Prefix: elektraKdb*
libelektra-lowlevel-c
: Additional C APIs that are useful when working with ElektraKey
and ElektraKeyset
, but not are not minimal API. Specifically targets C and not intended for use via bindings.
Prefixes: elektraCKey*
, elektraCKeyset*
libelektra-highlevel-c
: The C high-level API for reading/writing configuration with Elektra. Intended for use by applications. Partially intended for use with code-generation. Specifically targets C and not intended for use via bindings.
Prefix: elektraHlc*
(Note: Even though there isn't any other highlevel
implementation, c
suffix to show this lib is only for C)
libelektra-opts
: The API for parsing command-line arguments according to Elektra's spec.
Prefix: elektraOpts*
libelektra-notification
: The API for setting up callbacks and automatically updated variables linked to changes in the KDB.
Prefix: elektraNotification*
libelektra-io
: Elektra's API for asynchronous operations.
Prefix: elektraIo*
libelektra-merge
: The API for merging and/or detecting conflicts between two keysets.
Prefix: elektraMerge*
libelektra-plugin
: The plugin API. It forms the base for all plugins and contains the functions required to implement a plugin. It also contains the API for interacting with (other) plugins. This includes loading plugins and calling exported functions.
Note: This library comes with two separate headers. One for implementing a plugin and another for loading/calling plugins.
Prefix: elektraPlugin*
(Note: previously libelektra-plugin
merged with libelektra-invoke
)
libelektra-pluginload
: Internal static library, linked into libelektra-plugin
(re-exported) and libelektra-kdb
(not exported). Contains the code for loading plugins.
Prefix:: elektraPlugin*
(shared with libelektra-plugin
because exported there)
libelektra-mount
: The API for manipulating mountpoints.
Prefix: elektraMount*
libelektra-type
: The API that defines Elektra's type system.
Names: elektra<TYPE>ToString
and elektraKeyTo<TYPE>
(Note: extracted from libelektra-ease
)
libelektra-extra
: Contains extra APIs for ElektraKey
and ElektraKeyset
beyond the minimal API of libelektra-core
. These APIs are things that could be considered part of the classes for ElektraKey
and ElektraKeyset
, but which we do not consider minimal. The APIs should not specifically target C (see libelektra-lowlevel-c
for that) and should be usable via bindings (if appropriate for the other language).
Prefix: elektraExtra*
(Note: includes elektraExtraKeysetCut
, etc.; may also include stuff from old libelektra-ease
or libelektra-meta
)
libelektra-ease
: A collection of various other APIs that help when interacting with ElektraKey
and ElektraKeyset
. These APIs go beyond what could be considered part of the "classes" for ElektraKey
and ElektraKeyset
(e.g., SHA256 hashes). The APIs should not specifically target C (see libelektra-lowlevel-c
for that) and should be usable via bindings (if appropriate for the other language).
Prefix: elektraEase*
(Note: rest of old libelektra-ease
, merged with libelektra-meta
; cleanup needed)
libelektra-utility
: Standalone helper functions that don't depend on libelektra-core
Prefix: elektraUtil*
libelektra-base
: Internal static library, linked into libelektra-core
(not exported) and libelektra-utility
(partially re-exported). Contains helper functions for e.g., memory allocations, string formatting, etc.
Prefix: elektra*
(for internal), elektraUtil*
(for exported)
