- <description summary="Protocol for composing text">
- This protocol allows compositors to act as input methods and to send text
- to applications. A text input object is used to manage state of what are
- typically text entry fields in the application.
-
- 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.

- <interface name="zwp_text_input_v3" version="1">
- <description summary="text input">
- The zwp_text_input_v3 interface represents text input and input methods
- associated with a seat. It provides enter/leave events to follow the
- text input focus for a seat.
-
- Requests are used to enable/disable the text-input object and set
- state information like surrounding and selected text or the content type.
- The information about the entered text is sent to the text-input object
- via the preedit_string and commit_string events.
-
- Text is valid UTF-8 encoded, indices and lengths are in bytes. Indices
- must not point to middle bytes inside a code point: they must either
- point to the first byte of a code point or to the end of the buffer.
- Lengths must be measured between two valid indices.
-
- Focus moving throughout surfaces will result in the emission of
- zwp_text_input_v3.enter and zwp_text_input_v3.leave events. The focused
- surface must commit zwp_text_input_v3.enable and
- zwp_text_input_v3.disable requests as the keyboard focus moves across
- editable and non-editable elements of the UI. Those two requests are not
- expected to be paired with each other, the compositor must be able to
- handle consecutive series of the same request.
-
- State is sent by the state requests (set_surrounding_text,
- set_content_type and set_cursor_rectangle) and a commit request. After an
- enter event or disable request all state information is invalidated and
- needs to be resent by the client.
- </description>
-
- <request name="destroy" type="destructor">
- <description summary="Destroy the wp_text_input">
- Destroy the wp_text_input object. Also disables all surfaces enabled
- through this wp_text_input object.
- </description>
- </request>
-
- <request name="enable">
- <description summary="Request text input to be enabled">
- Requests text input on the surface previously obtained from the enter
- event.
-
- This request must be issued every time the active text input changes
- to a new one, including within the current surface. Use
- zwp_text_input_v3.disable when there is no longer any input focus on
- the current surface.
-
- This request resets all state associated with previous enable, disable,
- set_surrounding_text, set_text_change_cause, set_content_type, and
- set_cursor_rectangle requests, as well as the state associated with
- preedit_string, commit_string, and delete_surrounding_text events.
-
- The set_surrounding_text, set_content_type and set_cursor_rectangle
- requests must follow if the text input supports the necessary
- functionality.
-
- State set with this request is double-buffered. It will get applied on
- the next zwp_text_input_v3.commit request, and stay valid until the
- next committed enable or disable request.
-
- The changes must be applied by the compositor after issuing a
- zwp_text_input_v3.commit request.

-
- <request name="set_surrounding_text">
- <description summary="sets the surrounding text">
- Sets the surrounding plain text around the input, excluding the preedit
- text.
-
- The client should notify the compositor of any changes in any of the
- values carried with this request, including changes caused by handling
- incoming text-input events as well as changes caused by other
- mechanisms like keyboard typing.
-
- If the client is unaware of the text around the cursor, it should not
- issue this request, to signify lack of support to the compositor.
-
- Text is UTF-8 encoded, and should include the cursor position, the
- complete selection and additional characters before and after them.
- 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 text buffer.
-
- Anchor is the byte offset of the selection anchor within text buffer.
- If there is no selected text, anchor is the same as cursor.
-
- If any preedit text is present, it is replaced with a cursor for the
- purpose of this event.
-
- Values set with this request are double-buffered. They will get applied
- on the next zwp_text_input_v3.commit request, and stay valid until the
- next committed enable or disable request.
-
- 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.

- <description summary="commit state">

- Text input state (enabled status, content purpose, content hint,
- surrounding text and change cause, cursor rectangle) is conceptually
- double-buffered within the context of a text input, i.e. between a
- committed enable request and the following committed enable or disable
- request.
-
- Protocol requests modify the pending state, as opposed to the current
- state in use by the input method. A commit request atomically applies
- all pending state, replacing the current state. After commit, the new
- pending state is as documented for each related request.
-
- Requests are applied in the order of arrival.
-
- Neither current nor pending state are modified unless noted otherwise.
-
- The compositor must count the number of commit requests coming from
- each zwp_text_input_v3 object and use the count as the serial in done
- events.
