-- 万象家族 lua,小键盘行为控制:
|
||
-- - 小键盘数字:根据 kp_number_mode 决定 “参与编码 / 直接上屏”
|
||
-- - 主键盘数字:在有候选菜单时,用于选第 n 个候选
|
||
--

||
-- 用法示例(schema.yaml):
|
||
-- engine:
|
||
-- processors:
|

-- - lua_processor@*kp_number_processor
|
||
-- # 小键盘模式(可省略,默认 auto)
|
||
-- # auto : 空闲时直接上屏,输入中参与编码
|
||
-- # compose : 无论是否在输入中,小键盘都参与编码(不直接上屏)
