From f25797f86976cbccf697d6df953154c5e59656e6 Mon Sep 17 00:00:00 2001 From: Rui Abreu Ferreira Date: Sun, 25 Sep 2016 18:46:37 +0100 Subject: api: Nvim version, API level #5386 The API level is disconnected from the NVIM version. The API metadata holds the current API level, and the lowest backwards-compatible level supported by this instance. Release 0.1.6 will be the first release reporting the Nvim version and API level. metadata['version'] = { major: 0, minor: 1, patch: 6, prerelease: true, api_level: 1, api_compatible: 0, } The API level may remain unchanged across Neovim releases if the API has not changed. When changing the API the CMake variable NVIM_API_PRERELEASE is set to true, and NVIM_API_CURRENT/NVIM_API_COMPATIBILITY are incremented accordingly. The functional tests check the API table against fixtures of past versions of Neovim. It compares all the functions in the old table with the new one, it does ignore some metadata attributes that do not alter the function signature or were removed since 0.1.5. Currently the only fixture is 0.mpack, generated from Neovim 0.1.5 with nvim --api-info. --- runtime/doc/api.txt | 1 + runtime/doc/msgpack_rpc.txt | 3 +++ 2 files changed, 4 insertions(+) (limited to 'runtime') diff --git a/runtime/doc/api.txt b/runtime/doc/api.txt index c3d7fdb35b..dd48a0c2a5 100644 --- a/runtime/doc/api.txt +++ b/runtime/doc/api.txt @@ -51,6 +51,7 @@ Tabpage -> enum value kObjectTypeTabpage Nvim exposes metadata about the API as a Dictionary with the following keys: +api_level API version compatibility information functions calling signature of the API functions types The custom handle types defined by Nvim error_types The possible kinds of errors an API function can exit with. diff --git a/runtime/doc/msgpack_rpc.txt b/runtime/doc/msgpack_rpc.txt index b3fed9e756..bfd4100f15 100644 --- a/runtime/doc/msgpack_rpc.txt +++ b/runtime/doc/msgpack_rpc.txt @@ -168,6 +168,9 @@ API metadata object ~ API clients exist to hide msgpack-rpc details.
