- * Tag a template literal string for localization.
- *
- * For example:
- *
- * ```ts
- * $localize `some string to localize`
- * ```
- *
- * **Providing meaning, description and id**
- *
- * You can optionally specify one or more of `meaning`, `description` and `id` for a localized
- * string by pre-pending it with a colon delimited block of the form:
- *
- * ```ts
- * $localize`:meaning|description@@id:source message text`;
- *
- * $localize`:meaning|:source message text`;
- * $localize`:description:source message text`;
- * $localize`:@@id:source message text`;
- * ```
- *
- * This format is the same as that used for `i18n` markers in Angular templates. See the
- * [Angular 18n guide](guide/i18n#template-translations).
- *
- * **Naming placeholders**
- *
- * If the template literal string contains expressions, then the expressions will be automatically
- * associated with placeholder names for you.
- *
- * For example:
- *
- * ```ts
- * $localize `Hi ${name}! There are ${items.length} items.`;
- * ```
- *
- * will generate a message-source of `Hi {$PH}! There are {$PH_1} items`.
- *
- * The recommended practice is to name the placeholder associated with each expression though.
- *
- * Do this by providing the placeholder name wrapped in `:` characters directly after the
- * expression. These placeholder names are stripped out of the rendered localized string.
- *
- * For example, to name the `items.length` expression placeholder `itemCount` you write:
- *
- * ```ts
- * $localize `There are ${items.length}:itemCount: items`;
- * ```
- *
- * **Escaping colon markers**
- *
- * If you need to use a `:` character directly at the start of a tagged string that has no
- * metadata block, or directly after a substitution expression that has no name you must escape
- * the `:` by preceding it with a backslash:
- *
- * For example:
- *
- * ```ts
- * // message has a metadata block so no need to escape colon
- * $localize `:some description::this message starts with a colon (:)`;
- * // no metadata block so the colon must be escaped
- * $localize `\:this message starts with a colon (:)`;
- * ```
- *
- * ```ts
- * // named substitution so no need to escape colon
- * $localize `${label}:label:: ${}`

- * transpiler, removing the tag and replacing the template literal string with a translated
- * literal string from a collection of translations provided to the transpilation tool.
- *
- * * **run-time evaluation**: the `$localize` tag is a run-time function that replaces and
- * reorders the parts (static strings and expressions) of the template literal string with strings
- * from a collection of translations loaded at run-time.
- *
- * * **pass-through evaluation**: the `$localize` tag is a run-time function that simply evaluates
- * the original template literal string without applying any translations to the parts. This
- * version is used during development or where there is no need to translate the localized
- * template literals.
- * @param messageParts a collection of the static parts of the template string.
- * @param expressions a collection of the values of each placeholder in the template string.
- * @returns the translated string, with the `messageParts` and `expressions` interleaved together.
