Since all API functions now run immediately after a msgpack-rpc request is
parsed by libuv callbacks, a mechanism was added to override this behavior and
allow certain functions to run in Nvim main loop.
The mechanism is simple: Any API function tagged with the FUNC_ATTR_DEFERRED (a
"dummy" attribute only used by msgpack-gen.lua) will be called when Nvim main
loop receives a K_EVENT key.
To implement this mechanism it was necessary some restructuration on the
msgpack-rpc modules, especially in the msgpack-gen.lua script.
Introducing the concept of providers: co-processes that talk with the editor
through the remote API and provide implementation for one or more core
services.
The `provider_register` function and it's API wrapper can be used by channels
that want to self-register as a service provider.
Some old builtin vim features will be re-implemented as providers. The
`provider_has_feature` function is used to check if a provider
implementing a certain feature is available(It will be called by the `has`
vimscript function to check for features in a vim-compatible way)
This implements the provider module without exposing any extension points, which
will be done in future commits.
- The 'stripdecls.py' script replaces declarations in all headers by includes to
generated headers.
`ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'`
was used for this.
- Add and integrate gendeclarations.lua into the build system to generate the
required includes.
- Add -Wno-unused-function
- Made a bunch of old-style definitions ANSI
This adds a requirement: all type and structure definitions must be present
before INCLUDE_GENERATED_DECLARATIONS-protected include.
Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is
the only exception.
This module will be used to implement remote management of objects through the
API. Object types to be registered must have a `uint64_t` field named 'handle'.
The map_* declarations and definitions are now created by a macro invocation
with a key type parameter. Also refactored server module to use the updated
version.
- Move `Map` structure definition to `map_defs.h`
- Use `KHASH_DECLARE` on map_defs.h to declare khash function prototypes.
- Redefine `map_foreach` into a macro
- Refactor server.c module to use the new `map_foreach` macro.
Move files from src/ to src/nvim/.
- src/nvim/ becomes the new root dir for nvim executable sources.
- src/libnvim/ is planned to become root dir of the neovim library.
