Definition

interface TextTemplateOptions

Field structure

Field	Type	Required	Description
observe	((result: string) => void | Promise<void>) | undefined	Optional	Read-only. Observer invoked with every rendered text.
errors	{ readonly missingField?: (key: string) => Error | string; } | undefined	Optional	Read-only. Builds the error for a slot the caller did not supply; receives the slot name.

Examples

• Presentation: field ownership and final output: The model fills only the fields it is assigned; fixed text, bound values, and semantic keys are owned by the program.
• Templates, semantic slots, and expression selection: The program owns templates and preference order, inserted values are replaced only once, and the App supplies the random source for variants.

First compose one piece of generated text

Beginner · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
  { id: 'reply', kind: 'text', fields: [{ id: 'text', owner: 'generated' }] },
]);
console.log(outputs.toModelSchema('reply'));
const output = outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal });
console.log(output.value);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
    { id: 'reply', kind: 'text', fields: [{ id: 'text', owner: 'generated' }] },
]);
console.log(outputs.toModelSchema('reply'));
const output = outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal });
console.log(output.value);

Let the program own the explanatory prefix in the same compose

Configuration · Node.js

TypeScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
  { id: 'reply', kind: 'master', master: '{{prefix}}{{text}}', fields: [
    { id: 'prefix', owner: 'constant', constantValue: '接口说明：' },
    { id: 'text', owner: 'generated' },
  ] },
]);
console.log(outputs.toModelSchema('reply')); // 只有 text 由模型填写
console.log(outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal }).value);

JavaScript

import { Presentation } from '@jangts/agent-core/kits/presentation';
const outputs = Presentation.defineOutputCatalog([
    { id: 'reply', kind: 'master', master: '{{prefix}}{{text}}', fields: [
            { id: 'prefix', owner: 'constant', constantValue: '接口说明：' },
            { id: 'text', owner: 'generated' },
        ] },
]);
console.log(outputs.toModelSchema('reply')); // 只有 text 由模型填写
console.log(outputs.compose({ outputId: 'reply', input: { generated: { text: '普通对象即可定义节点。' } } }, { app: {}, signal: new AbortController().signal }).value);
