javascript - 如何使用 Globalizejs 验证 ICU 消息语法？

Question

JavaScript 中有一些可用的 i18n 库，最完整的库之一似乎是 GlobalizeJs .

在测试时，我发现发送无效 ICU 消息时出现问题。它似乎忽略了错误。示例如下:

    Globalize.loadMessages({
        en: {
            test1: [
                "You have {count, plural, one {# hot dog} one {# hamburger} one {# sandwich} other {# snacks}} in your lunch bag."
            ],
            test2: [
                "You have {count, plural, one {# hot dog} thisIsNotValid1 {# hamburger} thisIsNotValid2 {# sandwich} other {# snacks}} in your lunch bag."
            ]
        }
    });

    console.log(Globalize( 'en' ).messageFormatter( 'test1' )({count: 1}));
    // Output: You have 1 sandwich in your lunch bag.
    // Expected output: exception thrown because the plural "one" is used multiple times.
    console.log(Globalize( 'en' ).messageFormatter( 'test2' )({count: 1}));
    // Output: You have 1 hot dog in your lunch bag.
    // Expected output: exception thrown because the plural "thisIsNotValid1" and "thisIsNotValid2" are not valid.

有没有办法捕捉到 ICU 语法无效而不是默默地输出最大努力的结果？

也许可以使用 https://github.com/messageformat/messageformat/tree/master/packages/parser (或其修改版本)来检测您正在寻找的无效语法
