resolvePreference
KIT · function · 运行时值
Resolve the preferred candidate.
Highest priority wins; order breaks ties with the later entry first, so recency can be encoded without touching priority. The input array is copied before sorting.

使用示例
- 模板、语义槽与表达选择：程序拥有模板和偏好顺序，插入值只替换一次，变体随机源由 App 提供。
先用程序模板组合说明
入门 · Node.js
ts
import { Presentation } from '@jangts/agent-core/kits/presentation';
const template = Presentation.defineTextTemplate('你好，{{name}}。{{body}}');
console.log(template.render({ name: '开发者', body: '普通对象也能实现接口。' }));js
import { Presentation } from '@jangts/agent-core/kits/presentation';
const template = Presentation.defineTextTemplate('你好，{{name}}。{{body}}');
console.log(template.render({ name: '开发者', body: '普通对象也能实现接口。' }));相同模板加语义键校验与不重复变体
配置 · Node.js
ts
import { Presentation } from '@jangts/agent-core/kits/presentation';
const slots = Presentation.defineSemanticSlots({ namespace: 'tone', keys: ['brief', 'detailed'], maxOccurrences: 1 });
console.log(slots.isValid('{{tone:brief}}'));
const greeting = Presentation.selectVariant(['你好', '欢迎'], { previous: '你好', randomIndex: () => 0 });
const tone = Presentation.resolvePreference([{ value: 'brief', priority: 1, order: 0 }, { value: 'detailed', priority: 2, order: 1 }]);
const template = Presentation.defineTextTemplate('{{greeting}}，{{body}}');
console.log(template.render({ greeting: greeting ?? '你好', body: tone === 'detailed' ? '下面逐步说明接口。' : '普通对象即可。' }));js
import { Presentation } from '@jangts/agent-core/kits/presentation';
