CLDR Plural Rule Evaluator
git clone https://github.com/santhoshtr/CLDRPluralRuleParser.git
Unlike English, for many languages, the plural forms are just not 2 forms.
If you look at the CLDR plural rules table
you can easily understand this. The rules are defined in a particular syntax
(an eg: for Russian, the plural few is applied when the rule
n mod 10 in 2..4 and n mod 100 not in 12..14;" is passed).
For a given number in a language, this tool tells which plural form it belongs. The plural rules are taken from the CLDR data file
./test/index.html in your browser.
This is also available as a node module. You can install it using:
npm install cldrpluralruleparser
Once installed it provides a command line utility named cldrpluralruleparser too.
$ cldrpluralruleparser 'n is 1' 0 false
