Run WritePluralRulesSpreadsheets.java

Q: Is the output supposed to be captured somewhere? Prints stuff to console.

Adding rules for a locale

• Add the new plural and ordinal rules to plurals.xml and ordinals.xml.
• Run GeneratedPluralSamples as below.
• Add the minimal pairs to the locale.

Changing rules/ranges

Whenever you change plural rules, ordinal rules, or plural ranges — and at the end of the release — you must do the following. The reformatting is required, since it regenerates the samples (after @), which are now necessary for correct functioning of ICU and other clients.

1. Run GeneratePluralRanges.java to reformat pluralRanges.xml
   • Overwrites cldr/common/supplemental/pluralRanges.xml in place.
   • Diff, commit if changed.
2. Run GeneratedPluralSamples to reformat plurals.xml, ordinals.xml.
   • Overwrites cldr/common/supplemental/plurals.xml and cldr/common/supplemental/ordinals.xml in place.
   • Diff, commit if changed.
3. Run GenerateAllCharts (actually, it is enough to run ShowLanguages) and the unit tests.
   • This will insure that the rules are correctly represented, and aligned with the minimal pairs.
   • Diff the plurals chart against the old one: eg v.s. https://unicode-org.github.io/cldr-staging/charts/38/supplemental/language_plural_rules.html 1. Run FindPluralDifferences to see that the expected changes are there (only tests integers right now). - Modify the versions variable to use the last release. - This is also run at the end of the release to get the Migration info for the release.
4. Compare the results carefully, then check in.
