如何使用 Globalizejs 驗證 ICU 消息語法？

Question

JavaScript 中有一些 i18n 庫可用，其中最完整的庫之一似乎是GlobalizeJs 。

在測試它時，我發現當我發送無效的 ICU 消息時出現問題。 它似乎忽略了錯誤。 下面的例子：

    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.

有沒有辦法發現 ICU 語法無效，而不是默默地輸出盡力而為的結果？

可以使用https://github.com/messageformat/messageformat/tree/master/packages/parser （或它的修改版本）來檢測您正在尋找的無效語法
