<description summary="Protocol for creating input methods">
|
||||||
|
This protocol allows applications to act as input methods for compositors.
|
||||||
|
|
||||||
|
An input method context is used to manage the state of the input method.
|
||||||
|
|
||||||
|
Text strings are UTF-8 encoded, their indices and lengths are in bytes.
|
||||||
|
|
||||||
|
This document adheres to the RFC 2119 when using words like "must",
|
||||||
|
"should", "may", etc.
|
||||||
|
|
||||||
|
Warning! The protocol described in this file is experimental and
|
||||||
|
backward incompatible changes may be made. Backward compatible changes
|
||||||
|
may be added together with the corresponding interface version bump.
|
||||||
|
Backward incompatible changes are done by bumping the version number in
|
||||||
|
the protocol and interface names and resetting the interface version.
|
||||||
|
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||||
|
version number in the protocol and interface names are removed and the
|
||||||
|
interface version number is reset.

<description summary="input method">
|
||||||
|
An input method object allows for clients to compose text.
|
||||||
|
|
||||||
|
The objects connects the client to a text input in an application, and
|
||||||
|
lets the client to serve as an input method for a seat.
|
||||||
|
|
||||||
|
The zwp_input_method_v2 object can occupy two distinct states: active and
|
||||||
|
inactive. In the active state, the object is associated to and
|
||||||
|
communicates with a text input. In the inactive state, there is no
|
||||||
|
associated text input, and the only communication is with the compositor.
|
||||||
|
Initially, the input method is in the inactive state.
|
||||||
|
|
||||||
|
Requests issued in the inactive state must be accepted by the compositor.
|
||||||
|
Because of the serial mechanism, and the state reset on activate event,
|
||||||
|
they will not have any effect on the state of the next text input.
|
||||||
|
|
||||||
|
There must be no more than one input method object per seat.

|

|
Notification that a text input focused on this seat requested the input
|
||||||

method to be activated.
|
||||||
|
|
||||||
|
This event serves the purpose of providing the compositor with an
|
||||||
|
active input method.
|
||||||
|
|
||||||
|
This event resets all state associated with previous enable, disable,
|
||||||
|
surrounding_text, text_change_cause, and content_type events, as well
|
||||||
|
as the state associated with set_preedit_string, commit_string, and
|
||||||
|
delete_surrounding_text requests. In addition, it marks the
|
||||||
|
zwp_input_method_v2 object as active, and makes any existing
|
||||||
|
zwp_input_popup_surface_v2 objects visible.
|
||||||
|
|
||||||
|
The surrounding_text, and content_type events must follow before the

next done event if the text input supports the respective

functionality.
|

State set with this event is double-buffered. It will get applied on

If any preedit text is present, it is replaced with the cursor for the

|
The argument text is a buffer containing the preedit string, and must
|
||||||
|
include the cursor position, and the complete selection. It should
|
||||||
|
contain additional characters before and after these. There is a
|

maximum length of wayland messages, so text can not be longer than 4000

|
bytes.
|

|
cursor is the byte offset of the cursor within the text buffer.
|

anchor is the byte offset of the selection anchor within the text
|
||||||
|
buffer. If there is no selected text, anchor must be the same as
|
||||||
|
cursor.
|
||||||
|
|
||||||
|
If this event does not arrive before the first done event, the input
|

method may assume that the text input does not support this

event.
|

The initial state for affected fields is empty, meaning that the text

input does not support sending surrounding text. If the empty values

get applied, subsequent attempts to change them may have no effect.

|
Whenever the client detects an external change in text, cursor, or

|
anchor position, it must issue this request to the compositor. This

request is intended to give the input method a chance to update the

Text input state (content purpose, content hint, surrounding text, and

<description summary="apply state">
|

|
Apply state changes from commit_string, set_preedit_string and
|
||||||
|
delete_surrounding_text requests.
|
||||||
|
|
||||||
|
The state relating to these events is double-buffered, and each one
|
||||||
|
modifies the pending state. This request replaces the current state
|
||||||
|
with the pending state.
|
||||||
|
|
||||||
|
The connected text input is expected to proceed by evaluating the
|
||||||
|
changes in the following order:
|
||||||
|
|
||||||
|
1. Replace existing preedit string with the cursor.
|
||||||
|
2. Delete requested surrounding text.
|
||||||
|
3. Insert commit string with the cursor at its end.
|
||||||
|
4. Calculate surrounding text to send.
|
||||||
|
5. Insert new preedit text in cursor position.
|
||||||
|
6. Place cursor inside preedit text.
|
||||||
|
|
||||||
|
The serial number reflects the last state of the zwp_input_method_v2
|
||||||
|
object known to the client. The value of the serial argument must be
|
||||||
|
equal to the number of done events already issued by that object. When
|
||||||
|
the compositor receives a commit request with a serial different than
|
||||||
|
the number of past done events, it must proceed as normal, except it
|
||||||
|
should not change the current state of the zwp_input_method_v2 object.
