ICU MessageFormat Syntax Cheat Sheet
快速语法规则以及每个模式如何映射到 Intlayer 的类型安全声明
| 功能 | 语法 | 示例 | 备注 | Intlayer 等效写法 |
|---|---|---|---|---|
| Simple Variable | {variableName} | Hello {name}! | Alphanumeric names, single brackets | {{name}} |
| Pluralization | {count, plural, one {...} other {...}} | {n, plural, one {# item} other {# items}} | Requires "other". # is replaced by count. | plural({ one: "1 item", other: "{{count}} items" }) |
| Exact Match Plural | =0 {...} =1 {...} | {n, plural, =0 {None} one {#} other {#}} | Takes precedence over CLDR keywords | enu({ 0: "None", 1: "1", fallback: "{{count}}" }) |
| Select (Context/Gender) | {key, select, choice1 {...} other {...}} | {gender, select, male {He} other {They}} | Case-sensitive exact string comparison | select({ male: "He", fallback: "They" }, "gender") |
| Selectordinal | {rank, selectordinal, one {#st} other {#th}} | {pos, selectordinal, one {#st} two {#nd} other {#th}} | Ordinal suffix rules per CLDR | enu({ 1: "1st", 2: "2nd", fallback: "{{pos}}th" }) |
| Number Formatting | {val, number, [style]} | {price, number, currency} | Supports percent, currency, integer styles | Intl.NumberFormat or type-safe formatting |
| Escaping | '{' and '' for apostrophes | Don''t '{'escape'}' | Single quotes escape literal blocks, '' escapes quote | Literal strings naturally supported |
Intlayer 基于编译器的架构用编译时类型安全和自动化提取取代了复杂的运行时消息解析。
