Translate Variables With Pluralization and Nesting

Figma plugin interfaces often need localized strings with dynamic values. Implement a translator that renders a template using a nested values object, supporting simple variables, dotted paths, and pluralization blocks.

Use these forms:

1. Simple variable: {user.name}
2. Plural block: {count, plural, one{...} other{...}}
3. Plural branches may contain more variables or nested plural blocks.

For a plural block, render the one branch only when the resolved count equals 1; render other for every other count. Variable values are scalar strings or numbers, and nested objects are accessed with dot-separated paths. Templates are guaranteed to be syntactically valid and contain both one and other branches for every plural block.

Formal specification

Implement translate(template, values), where template is a string and values is a nested dictionary. Return the fully rendered string. A missing path is not included in valid input.

Examples

Example 1

Input: template = "I like {pet.name}.", values = {"pet": {"name": "dogs"}}

Output: "I like dogs."

The dotted path resolves values["pet"]["name"].

Example 2

Input: template = "{count, plural, one{{count} dog} other{{count} dogs}}", values = {"count": 2}

Output: "2 dogs"

The count is not 1, so the other branch is selected.
