Overview ¶
Package i18n formats translated messages. It implements the same message syntax and plural rules as the client runtime (packages/tern/src/runtime/ i18n), and both are tested against testdata/cases.json, so the server and the browser always produce the same text.
Messages support a subset of ICU MessageFormat:
Hello, {name}!
{count, plural, =0 {No items} one {# item} other {# items}}
{role, select, admin {Administrator} other {Member}}
Quote braces with apostrophes ('{'), and write an apostrophe as ”.

Functions ¶
Types ¶
type Catalog ¶
Catalog holds every locale's messages, flattened to dotted keys.
func Load ¶
Load reads <locale>.json files from fsys. defaultLocale must be one of them; if it is "", "en" is used when present, else the first locale.
func (*Catalog) Canonical ¶ added in v1.2.0
Canonical rewrites a URL path that starts with a locale, such as /de/projekte/42, to the route directories' names, /de/projects/42, so it matches the routes. Other paths are returned unchanged.
func (*Catalog) Match ¶
Match picks the best supported locale for an Accept-Language header, or "" if none fits.
func (*Catalog) Missing ¶
Missing returns, for each other locale, the default locale's keys it lacks.
func (*Catalog) RouteSegments ¶ added in v1.2.0
RouteSegments returns a locale's translations of URL path segments, from route directory names to the words in its URLs.
