Consider: `let vim = rpcstart('nvim', ['--embed'])`
Allows `rpcnotify(vim, ...)` to work like an asynchronous
`rpcrequest(nvim, ...)`.

We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
Most internal functions to modify buffers operate on the current buffer and
require temporary switchs. This macro is a temporary workaround until a cleaner
refactoring of the internal API is performed.
- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code
Instead of using classic cterm color numbers and attributes, treat "abstract_ui"
as a GUI: Pass rgb color numbers and gui attributes when the "highlight_set" UI
method is called. The terminal UI will have to translate RGB color information
to an appropriate color number, and the "term"/"cterm" :highlight keys will
eventually be deprecated.
- By default vim_feedkeys escaped all input for CSI/K_SPECIAL bytes
before using it. However since vim_replace_termcodes() also escapes
the input string chaining these functions together escapes input twice
- vim_feedkeys() now takes a third Boolean argument to enable/disable
escaping
- Breaks API compatibility
The `vim_feedkeys` must be deferred because it can potentially free the buffer
passed to `os_inchar`(which in turns calls `vim_feedkeys` indirectly).
The new `vim_input` function can be used to emulate user input(Since it does not
mess with the typeahead, it is safe to execute without deferring).
- Expose more logging control from the log.c module(get log stream and omit
newlines)
- Remove logging from the generated functions in msgpack-gen.lua
- Refactor channel.c/helpers.c to log every msgpack-rpc payload using
msgpack_object_print(a helper function from msgpack.h)
- Remove the api_stringify function, it was only useful for logging msgpack-rpc
which is now handled by msgpack_object_print.
- Add error type information to `Error`
- Rename `set_api_error` to `api_set_error` for consistency with other api_*
functions/macros.
- Refactor the api_set_error macro to accept formatted strings and error types
- Improve error messages
- Wrap error messages with gettext macro
- Refactor msgpack-rpc serialization to transform Error instances into [type,
message] arrays
- Add error type information to API metadata
- Normalize nvim->client and client->nvim error handling(change
channel_send_call to accept an Error pointer instead of the `errored` boolean
pointer)
- Use macro to initialize Error structures
Adapt gendeclarations.lua/msgpack-gen.lua to allow the `ArrayOf(...)` and
`DictionaryOf(...)` types in function headers. These are simple macros that
expand to Array and Dictionary respectively, but the information is kept in the
metadata object, which is useful for building clients in statically typed
languages.
Instead of building all metadata from msgpack-gen.lua, we now merge the
generated part with manual information(such as types and features). The metadata
is accessible through the api method `vim_get_api_info`.
This was done to simplify the generator while also increasing flexibility(by
being able to add more metadata)
- Providers for features are now registered as a unit. For example, instead of
calling `register_provider("clipboard_get")` and
`register_provider("clipboard_set")`, clients call
`register_provider("clipboard")` and nvim will assume it implements all
methods of the "clipboard" feature
- Bootstrapping code was removed. With the `api_spawn` function exposed to
vimscript, it's no longer necessary and will be handled by plugins
distributed with nvim.
- Now the `has` function will return true if there's a live channel that
has registered as a provider for the feature.
- 'initpython'/'initclipboard' options were removed
- A new API function was exposed: `vim_discover_features` which returns an
object with information about pluggable features such as 'python' or
'clipboard'
Enhance msgpack-gen.lua to extract custom api type codes from the ObjectType
enum in api/private/defs.h. The type information is made available from the api
metadata and clients can use to correctly serialize/deserialize these types
using msgpack EXT type.
Specialized array types(BufferArray, WindowArray, etc) were added to the API for
two main reasons:
- msgpack used to lack a way of serializing appliaction-specific types and there
was no obvious way of making an API function accept/return arrays of custom
objects such as buffers(which are represented as integers, so clients didn't
have a way to distinguish from normal numbers)
- Let clients in statically-typed languages that support generics have a better
typed API
With msgpack 2.0 EXT type the first item is no longer a factor and this commit
starts by removing the specialized array types. The second item will be
addressed in the future by making the API metadata return extra useful
information for statically-typed languages.
- To clean up the mix between feedkeys and replace_termcodes
the vim_feedkeys API function now does the same thing as the
vimscript feedkeys() function
- The original f_feedkeys() function now calls the vim_feedkeys()
function from the API
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.
`-Wstrict-prototypes` warn if a function is declared or defined without
specifying the argument types.
This warning disallow function prototypes with empty parameter list.
In C, a function declared with an empty parameter list accepts an
arbitrary number of arguments when being called. This is for historic
reasons; originally, C functions didn't have prototypes, as C evolved
from B, a typeless language. When prototypes were added, the original
typeless declarations were left in the language for backwards
compatibility.
Instead we should provide `void` in argument list to state
that function doesn't have arguments.
Also this warning disallow declaring type of the parameters after the
parentheses because Neovim header generator produce no declarations for
old-stlyle prototypes: it expects to find `{` after prototype.
