Namespaces is a lightweight concept that should be used to group
objects for purposes of bulk operations and introspection. This is
initially used for highlights and virtual text in buffers, and is
planned to also be used for extended marks. There is no plan use them
for privileges or isolation, neither to introduce nanespace-level
options.
msgpack_rpc_to_object (called by handle_request .. msgpack_rpc_to_array)
always NUL-terminates API Strings.
But handle_request .. msgpack_rpc_get_handler_for operates on a raw
msgpack_object, before preparation.
Add ext_newgrid and ext_hlstate extensions. These use predefined
highlights and line-segment based updates, for efficiency and
simplicity.. The ext_hlstate extension in addition allows semantic
identification of builtin and syntax highlights.
Reimplement the old char-based updates in the remote UI layer, for
compatibility. For the moment, this is still the default. The bulitin
TUI uses the new line-based protocol.
cmdline uses curwin cursor position when ext_cmdline is active.
- Return VimL errors instead of generic errors for:
- nvim_call_function
- nvim_call_dict_function
- Fix tests which were silently broken before this change.
This violates #6150 where we agreed not to translate API errors. But
that can be fixed later.
The `internal` param is difficult to explain, and will rarely be
anything but `true`. To avoid it, use a hack: check if the resolved
dict value starts with "function(".
Make `:verbose set ...` show when an option was last modified by an
API client or Lua script/chunk. In the case of an API client, the
channel ID is displayed.
Implement nvim_command_output with `execute({cmd},"silent")`.
Behavior changes:
- does not provoke any hit-enter prompt
- no longer prepends a newline char
- does not capture some noise (like the "[New File]" message, see the
change to tabnewentered_spec.lua)
Technically ("bug-for-bug") this a breaking change. But the previous
behavior of nvim_command_output meant that it probably wasn't used for
anything outside of tests.
Also remove the undocumented `v:command_output` variable which was
a hack introduced only for the purposes of nvim_command_output.

The "mapping" tests added in 541dde36e3 were flawed:
- Unlike op-pending mode, RPCs are _blocked_ during map-pending. So
a synchronous RPC like nvim_get_current_buf() waits until
'timeoutlen', then the mapping is canceled.
- helpers.expect() also performs a blocking RPC, so again that must not
intervene the two nvim_input() calls.
closes#6166
normal_finish_command() and normal_prepare() assume that any pending
operator needs to be finished after any subsequent key.
Set `finish_op = false` in nv_event() to indicate that the pending
operator shouldn't be finished in normal_execute().
This is how nv_visual() indicates that 'v' or 'V' in operator-pending
mode should not finish the current pending operator.
fixes#5398fixes#6166 (partially; mappings are still interrupted)
Asynchronous API functions are served immediately, which means pending
input could change the state of Nvim shortly after an async API function
result is returned.
nvim_get_mode() is different:
- If RPCs are known to be blocked, it responds immediately (without
flushing the input/event queue)
- else it is handled just-in-time before waiting for input, after
pending input was processed. This makes the result more reliable
(but not perfect).
Internally this is handled as a special case, but _semantically_ nothing
has changed: API users never know when input flushes, so this internal
special-case doesn't violate that. As far as API users are concerned,
nvim_get_mode() is just another asynchronous API function.
In all cases nvim_get_mode() never blocks for more than the time it
takes to flush the input/event queue (~µs).
Note: This doesn't address #6166; nvim_get_mode() will provoke #6166 if
e.g. `d` is operator-pending.
Closes#6159
Also re-word some error messages:
- "Key does not exist: %s"
- "Invalid channel: %<PRIu64>"
- "Request array size must be 4 (request) or 3 (notification)"
- "String cannot contain newlines"
