* test_meow_ui_vol.c — 宿主单元测试：SDK 状态栏音量换算纯函数 + settings.conf 读取。
|
||
*
|
||
* 直接编译 meow_ui_vol.c（纯函数，无 meow_ui 依赖），用临时 settings 文件验证：
|
||
* V1 解析：launcher 落盘 "key = value"（带空格）形式能正确读到值（根因回归——
|
||
* 旧代码朴素前缀匹配 "audio.volume=" 永远读不到 → 卡默认 60）；
|
||
* V2 解析：无空格 "key=value" / 多空格 / 头注释行 / 键缺失回退默认 / 精确匹配
|
||
* （audio.volume 不误配 audio.volume_max）；
|
||
* V3 clamp：volume_max 上限、硬上限 100、负值兜底 0、上限异常（<0）兜底 0；
|
||
* V4 管道（镜像 meow_ui_sys.c settings_vol）：读 + clamp 到 volume_max；
|
||
* V5 展示串：与 meow_ui_sys.c statusbar_right_str 同款 "VOL %d%%"，断言显示值即
|
||
* 当前夹后音量（含 step 语义：a.volume_step 只决定步进，展示原样不/舍入）。
|
||
*
|
||
* 编译（宿主 gcc，mipsel 无关）：
|
||
* gcc -o test_meow_ui_vol test_meow_ui_vol.c meow_ui_vol.c -I.
