<interface name="zwp_text_input_v1" version="1">
<description summary="text input">
An object used for text input. Adds support for text input and input
methods to applications. A text_input object is created from a
wl_text_input_manager and corresponds typically to a text entry in an
application.
Requests are used to activate/deactivate the text_input object and set
state information like surrounding and selected text or the content type.
The information about entered text is sent to the text_input object via
the pre-edit and commit events. Using this interface removes the need
for applications to directly process hardware key events and compose text
out of them.
Text is generally UTF-8 encoded, indices and lengths are in bytes.
Serials are used to synchronize the state between the text input and
an input method. New serials are sent by the text input in the
commit_state request and are used by the input method to indicate
the known text input state in events like preedit_string, commit_string,
and keysym. The text input can then ignore events from the input method
which are based on an outdated state (for example after a reset).
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="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.

<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.
Clients must not enable more than one text input on the single seat
and should disable the current text input before enabling the new one.
At most one instance of text input may be in enabled state per instance,
Requests to enable the another text input when some text input is active
must be ignored by compositor.
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.
</description>
</request>
<request name="disable">
<description summary="Disable text input on a surface">
Explicitly disable text input on the current surface (typically when
there is no focus on any text entry inside the surface).

the next zwp_text_input_v3.commit request.
</description>
</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.

double-buffered within the context of a text input, i.e. between a

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.

arguments can always be passed unmodified to this function. arguments can always be passed unmodified to this function.
@section ime_support IME support
IME (Input Method Editor/Engine) is used to input characters not mapped with
physical keys. It is popular among East Asian people.
@subsection ime_style IME styles
GLFW supports the following two styles of IME.
- On-the-spot
- Over-the-spot
On-the-spot style is supported on Windows, macOS and Wayland. On these platforms,
applications need to draw preedit text directly in their UI by using the preedit
callback (See [Preedit input](@ref input_preedit)).
Over-the-spot style is supported on X11. On this platform, the IME displays preedit
text, and applications don't need to draw it. So the preedit callback doesn't work
on X11.
In both styles, applications should manage the position of the candidate window.
See [Candidate window](@ref candidate_window) for details.
@note
@x11 You can use on-the-spot style also on X11 by using @ref GLFW_X11_ONTHESPOT_hint.
In this case, the preedit callback also works on X11. However, on-the-spot style on
X11 is unstable, so it is not recommended.
@subsection input_preedit Preedit input
When inputting text with IME, the text is temporarily inputted, then conversion
and other processing are performed and finally committed. The committed text is
inputted in the same way as input without IME (See [Text input](@ref input_char)).
This temporary input is called "preedit" or "pre-edit".
On Windows, macOS and Wayland, that use on-the-spot sytle, applications need to
take preedit information and draw it in their UI.
You can register the preedit callback as follows.
@code
glfwSetPreeditCallback(window, preedit_callback);
@endcode
The callback receives the following information.
@code
void preedit_callback(GLFWwindow* window,
int preedit_count,
unsigned int* preedit_string,
int block_count,
int* block_sizes,
int focused_block,
int caret)
{
}
@endcode
"preedit_count" and "preedit_string" parameter represent the whole preedit text.
Each character of the preedit string is a native endian UTF-32 like @ref input_char.
If you want to type the text "寿司(sushi)", Usually the callback is called several
times like the following sequence:
-# key event: s
-# preedit: [preedit_string: "ｓ", block_sizes: [1], focused_block: 0]
-# key event: u
-# preedit: [preedit_string: "す", block_sizes: [1], focused_block: 0]
-# key event: s
-# preedit: [preedit_string: "すｓ", block_sizes: [2], focused_block: 0]
-# key event: h
-# preedit: [preedit_string: "すｓｈ", block_sizes: [3], focused_block: 0]
-# key event: i
-# preedit: [preedit_string: "すし", block_sizes: [2], focused_block: 0]
-# key event: ' '
-# preedit: [preedit_string: "寿司", block_sizes: [2], focused_block: 0]
-# char: '寿'
-# char: '司'
-# preedit: [preedit_string: "", block_sizes: [], focused_block: 0]
If preedit text includes several semantic blocks, the callback returns several blocks:
-# preedit: [preedit_string: "わたしはすしをたべます", block_sizes: [11], focused_block: 0]
-# preedit: [preedit_string: "私は寿司を食べます", block_sizes: [2, 7], focused_block: 1]
"block_sizes" is a list of the sizes of each block. The above case, it contains the following
blocks and the second block is focused.
- 私は
- [寿司を食べます]
The application side should draw a focused block and unfocused blocks
in different styles.
You can use the "caret" parameter to draw the caret of the preedit text.
The specification of this parameter depends on the specification of the input method.
The following is an example on Win32.
- "あいうえお|" (caret: 5)
- key event: arrow-left
- "あいうえ|お" (caret: 4)
- ...
- "|あいうえお" (caret: 0)
@subsection candidate_window Candidate window
The application has to manage the position of the candidate window that shows
the preedit candidate list. To do this, the application has to manage the area
of the preedit text cursor by the following functions. The IME displays the
candidate window in the appropriate position based on the area of the preedit
text cursor.
@code
glfwSetPreeditCursorRectangle(window, x, y, w, h);
glfwGetPreeditCursorRectangle(window, &x, &y, &w, &h);
@endcode
@subsection ime_status IME status
Sometimes, IME task needs to be interrupted by a user or an application. There
are several functions to support these situations.
@note
@x11 @wayland This feature is not supported.
You can receive notification about IME status change(on/off) by using the following
function:
@code
glfwSetIMEStatusCallback(window, imestatus_callback);
@endcode
The callback has a simple signature like this:
@code
void imestatus_callback(GLFWwindow* window)
{
}
@endcode
@anchor GLFW_IME
You can get the current IME status by the following function:
@code
glfwGetInputMode(window, GLFW_IME);
@endcode
If you get GLFW_TRUE, it means the IME is on, and GLFW_FALSE means the IME is off.
You can also change the IME status by the following function:
@code
glfwSetInputMode(window, GLFW_IME, GLFW_TRUE);
glfwSetInputMode(window, GLFW_IME, GLFW_FALSE);
@endcode
You can use the following function to clear the current preedit.
@code
glfwResetPreeditText(window);
@endcode
@subsection manage_preedit_candidate Manage preedit candidate
By default, the IME manages the drawing of the preedit candidates, but
sometimes you need to do that on the application side for some reason. In such
a case, you can use
[GLFW_MANAGE_PREEDIT_CANDIDATE](@ref GLFW_MANAGE_PREEDIT_CANDIDATE_hint) init hint.
By setting this to `GLFW_TRUE`, the IME stops managing the drawing of the
candidates and the application needs to manage it by using the following
functions.
@note
@win32 Only the OS currently supports this hint.
You can register the candidate callback as follows.
@code
glfwSetPreeditCandidateCallback(window, candidate_callback);
@endcode
The callback receives the following information.
@code
void candidate_callback(GLFWwindow* window,
int candidates_count,
int selected_index,
int page_start,
int page_size)
{
}
@endcode
`candidates_count` is the number of total candidates. `selected_index` is the
index of the currently selected candidate. Normally all candidates should not
be displayed at once, but divided into pages. You can use `page_start` and
`page_size` to manage the pages. `page_start` is the index of the first
candidate on the current page. `page_size` is the number of the candidates on
the current page.
You can get the text of the candidate on the specific index as follows. Each
character of the returned text is a native endian UTF-32.
@code
int text_count;
unsigned int* text = glfwGetPreeditCandidate(window, index, &text_count);
@endcode
A sample code to get all candidate texts on the current page is as follows.
@code
void candidate_callback(GLFWwindow* window, int candidates_count,
int selected_index, int page_start, int page_size)
{
int i, j;
for (i = 0; i < page_size; ++i)
{
int index = i + page_start;
int text_count;
unsigned int* text = glfwGetPreeditCandidate(window, index, &text_count);
if (index == selected_index)
printf("> ");
for (j = 0; j < text_count; ++j)
{
char encoded[5] = "";
encode_utf8(encoded, text[j]); // Some kind of encoding process
printf("%s", encoded);
}
printf("\n");
}
}
glfwSetPreeditCandidateCallback(window, candidate_callback);
