Rime librime schema ascii_mode label get_state_label_abbreviated UTF-8 schema label documentation
💡 Result:
In the Rime input method engine, ascii_mode is a common state or switch that toggles between inputting characters (e.g., Chinese) and standard ASCII text [1][2]. The API function get_state_label_abbreviated [1][3] is part of the librime C interface and is used by frontend applications to retrieve human-readable labels for switch states (such as ascii_mode) [4]. Key details regarding this functionality include: 1. API Function: get_state_label_abbreviated(RimeSessionId session_id, const char* option_name, Bool state, Bool abbreviated) [1][3]. - option_name: The name of the switch (e.g., "ascii_mode"). - state: The boolean state to query. - abbreviated: A boolean flag. When set to true, the function returns an abbreviated version of the label (suitable for compact UI components like status bars); when false, it returns the full label (often used in menus) [4]. - It returns a RimeStringSlice structure [1][3]. 2. Schema Configuration: Authors can customize these labels within the Rime schema YAML files [4]. While previously labels were often extracted by taking the first character, modern librime supports an explicit abbrev property within the switches configuration in YAML [4]. - Example: switches: - name: ascii_mode states: [中文, ABC] abbrev: [中, A] 3. Usage: This mechanism allows frontend developers to present UI elements that are context-aware, providing full descriptive names when space permits and compact, user-defined abbreviations when in restricted environments, effectively solving issues with automatic truncation of multi-character or non-ASCII labels [2][4]. This API and configuration pattern ensures that input state indicators (like the "A" or "中" indicator in a status bar) remain consistent and configurable by the schema author rather than being hardcoded in the frontend application [2][4].

Use Unicode-aware conversion for schema labels.
Rime schema labels support non-ASCII text. Byte-wise std::toupper leaves UTF-8 characters unchanged, so école becomes éCOLE. Use a Unicode-aware conversion helper, or document and test ASCII-only support.

Currently, the Caps Lock label tip only appears when 'Use latin mode name defined in schema' is not enabled.
This feature would allow the Caps Lock label tip to show even when 'Use latin mode name defined in schema' is enabled.
It works by flipping the original tip to uppercase.
