stringsdict-test

Testing iOS/macOS plurals localization file format (stringsdict). Take aways:

• order of dictionaries doesn’t matter e.g.

  <key>fields</key>
  <dict>
      <key>NSStringFormatSpecTypeKey</key>
      <string>NSStringPluralRuleType</string>
      <key>NSStringFormatValueTypeKey</key>
      <string>d</string>
      <key>one</key>
      <string>%3$d field</string>
      <key>other</key>
      <string>%3$d fields</string>
  </dict>
  
  <key>geese</key>
  <dict>
      <key>NSStringFormatSpecTypeKey</key>
      <string>NSStringPluralRuleType</string>
      <key>NSStringFormatValueTypeKey</key>
      <string>d</string>
      <key>one</key>
      <string>%2$d goose</string>
      <key>other</key>
      <string>%2$d geese</string>
  </dict>

• indices on %#@...@ variables matter

  <key>NSStringLocalizedFormatKey</key>
  <string>%1$d: %3$#@geese@ landed on %2$#@fields@</string>

  is not the same as

  <key>NSStringLocalizedFormatKey</key>
  <string>%1$d: %2$#@geese@ landed on %3$#@fields@</string>

• indices of dictionaries should agree with indices of placeholders e.g. this won't work

  <key>geese.landed.ct</key>
  <dict>
      <key>NSStringLocalizedFormatKey</key>
      <string>%2$#@geese@ landed on %1$#@fields@</string>
      <key>geese</key>
      <dict>
          <key>NSStringFormatSpecTypeKey</key>
          <string>NSStringPluralRuleType</string>
          <key>NSStringFormatValueTypeKey</key>
          <string>d</string>
          <key>one</key>
          <string>%1$d goose</string>
          <key>other</key>
          <string>%1$d geese</string>
      </dict>
  
      <key>fields</key>
      <dict>
          <key>NSStringFormatSpecTypeKey</key>
          <string>NSStringPluralRuleType</string>
          <key>NSStringFormatValueTypeKey</key>
          <string>d</string>
          <key>one</key>
          <string>%2$d field</string>
          <key>other</key>
          <string>%2$d fields</string>
      </dict>
  </dict>
