LibreOffice API IDL Files Except UDK API
Contains all of the IDL files except those in udkapi.
i.e. the interfaces that are specific to the LibreOffice application. An artificial (?) separation.
The reference offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl (formerly combined into a single
offapi/type_reference/types.rdb) are used to detect inadvertent incompatible
changes. They are plain-text .idl files (not strictly lexicographically sorted,
though, so they satisfy the .idl file requirements for no forward dependencies),
so in cases where we deliberately /do/ become incompatible they can be modified
manually.
Old such cases of deliberately becoming incompatible are listed in
offapi/type_reference/typelibrary_history.txt, newer such cases are recorded in
the git logs of (now superseded) offapi/type_reference/types.rdb,
offapi/type_reference/offapi.rdb, and udkapi/type_reference/udkapi.rdb, new such
cases are recorded in the git logs of offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl.
