[go-i18n](https://github.com/nicksnyder/go-i18n) is one of the most popular internationalization (i18n) libraries for the Go programming language. Crowdin has native support for JSON files produced by go-i18n.



The placeholder syntax can be `{{ var }}`, `{var}`, or `%[1]d`. Crowdin will automatically detect the most widely used variable formats, and highlight and validate them in the editor.
