lingui library's macro t not working on react

问题

I use the latest library for translation, but the macro t not working, the <Trans> working fine.

To Reproduce

  1. open codesandbox
  2. yarn install
  3. yarn start
  4. click different language on the top of the screen

only content in <Trans>content<Trans> will be translated, but the last content on {hello react} is not translated.

import { LangSwitcher } from './components/lang-switcher';
import { DataComponent } from './components/DataComponent';

Here is the translated content:

每当在React应用程序中使用t宏时,您应该(1) 使用useLingui()钩子将您的组件“订阅”到更改,或者(2) - 使用defineMessage宏定义一个以后使用的消息。它具有与t相同的签名,并返回一个可传递给i18n._MessageDescriptor

我建议您修改您的代码如下:

index.tsx:

import React from "react";
import ReactDOM from "react-dom/client";
import reportWebVitals from "./reportWebVitals";
import { StoreProvider } from "./components/store-provider";
import createStore from "./store";
import { LanguageProvider } from "./components/language-provider";
import { LangSwitcher } from "./components/lang-switcher";
import { DataComponent } from "./components/DataComponent";
import { Trans } from "@lingui/macro";
import { msg } from "@lingui/macro";

const store = createStore();

const root = ReactDOM.createRoot(
  document.getElementById("root") as HTMLElement
);
root.render(
  <React.StrictMode>
    <StoreProvider store={store}>
      <LanguageProvider>
        <LangSwitcher />
        <p>
          <Trans>hello world</Trans>
        </p>
        <DataComponent data={msg`hello react`} />
      </LanguageProvider>
    </StoreProvider>
  </React.StrictMode>
);

reportWebVitals();

DataComponent.tsx:

import { MessageDescriptor } from "@lingui/core";
import { useLingui } from "@lingui/react";

type props = {
  data: MessageDescriptor;
};

export const DataComponent: React.FC<props> = ({ data }) => {
  const { i18n } = useLingui();

  return <p>{i18n._(data)}</p>;
};

sandbox中进行了测试,效果如预期。

英文:

Whenever you use the t macro in a React application, you should (1) "subscribe" your component to changes using the useLingui() hook, or (2) - use the defineMessage macro to define a message for later use. It has the same signature as t and returns a MessageDescriptor that you can pass to i18n._.

I would suggest modifying your code as follows:

index.tsx:

import React from &quot;react&quot;;
import ReactDOM from &quot;react-dom/client&quot;;
import reportWebVitals from &quot;./reportWebVitals&quot;;
import { StoreProvider } from &quot;./components/store-provider&quot;;
import createStore from &quot;./store&quot;;
import { LanguageProvider } from &quot;./components/language-provider&quot;;
import { LangSwitcher } from &quot;./components/lang-switcher&quot;;
import { DataComponent } from &quot;./components/DataComponent&quot;;
import { Trans } from &quot;@lingui/macro&quot;;
import { msg } from &quot;@lingui/macro&quot;;

const store = createStore();

const root = ReactDOM.createRoot(
  document.getElementById(&quot;root&quot;) as HTMLElement
);
root.render(
  &lt;React.StrictMode&gt;
    &lt;StoreProvider store={store}&gt;
      &lt;LanguageProvider&gt;
        &lt;LangSwitcher /&gt;
        &lt;p&gt;
          &lt;Trans&gt;hello world&lt;/Trans&gt;
        &lt;/p&gt;
        &lt;DataComponent data={msg`hello react`} /&gt;
      &lt;/LanguageProvider&gt;
    &lt;/StoreProvider&gt;
  &lt;/React.StrictMode&gt;
);

reportWebVitals();

DataComponent.tsx:

import { MessageDescriptor } from &quot;@lingui/core&quot;;
import { useLingui } from &quot;@lingui/react&quot;;

type props = {
  data: MessageDescriptor;
};

export const DataComponent: React.FC&lt;props&gt; = ({ data }) =&gt; {
  const { i18n } = useLingui();

  return &lt;p&gt;{i18n._(data)}&lt;/p&gt;;
};

Tested in the sandbox and it works as expected.
