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.
- New API function to push data to the typeahead buffer - this should
equivalent to the vimscript feedkeys() function
- In Vim there was a --remote-send command to insert input into a
Vim server instance. Besides accepting key sequences it also
translated special keys such as <CR> or <Leader>, backslash notation
is ignored. This commit backports the original Vim handler for
--remote-send as a bool option for vim_feedkeys()
- vim-patch:0
This is how API dispatching worked before this commit:
- The generated `msgpack_rpc_dispatch` function receives a the `msgpack_packer`
argument.
- The response is incrementally built while validating/calling the API.
- Return values/errors are also packed into the `msgpack_packer` while the
final response is being calculated.
Now the `msgpack_packer` argument is no longer provided, and the
`msgpack_rpc_dispatch` function returns `Object`/`Error` values to
`msgpack_rpc_call`, which will use those values to build the response in a
single pass.
This was done because the new `channel_send_call` function created the
possibility of having recursive API invocations, and this wasn't possible when
sharing a single `msgpack_sbuffer` across call frames(it was shared implicitly
through the `msgpack_packer` instance).
Since we only start to build the response when the necessary information has
been computed, it's now safe to share a single `msgpack_sbuffer` instance
across all channels and API invocations.
Some other changes also had to be performed:
- Handling of the metadata discover was moved to `msgpack_rpc_call`
- Expose more types as subtypes of `Object`, this was required to forward the
return value from `msgpack_rpc_dispatch` to `msgpack_rpc_call`
- Added more helper macros for casting API types to `Object`
any
This function is used to send RPC calls to clients. In contrast to
`channel_send_event`, this function will block until the client sends a
response(But it will continue processing requests from that client).
The RPC call stack has a maximum depth of 20.
- Generalize some argument names(event type -> event name,
event data -> event arg)
- Rename serialize_event to serialize_message
- Rename msgpack_rpc_notification to msgpack_rpc_message
- Extract the message type out of msgpack_rpc_message
- Add 'id' parameter to msgpack_rpc_message/serialize_message to create messages
that are not notifications
