Npm module for generating D3 Locale settings files based on Unicode CLDR JSON data
Inspired by Rafael Xavier de Souza's https://github.com/rxaviers/cldr-data-npm/tree/example-application
Make sure you run in root of sucrose (should already exist if you ran npm i earlier):
npm i cldr cldr-data cldrjs
To build locales, in root of sucrose run:
node ./scripts/lang/build_locales.js or make locales
which will make a hashmap of D3 localities in:
build/locales.json.
The build command will copy the locales file to the build folder.
To add or remove locales, edit the src/data/cldr-locales.json file using the pattern:
["xx_YY", "xx", "ZZZ", "xx-YY", "Klingon (Klinzhai)"]
where xx_YY is the locales.json key, xx is the ISO language code, ZZZ is the ISO currency code,
xx-YY is the node_modules/cldr/main/xx-YY data folder, followed by an english translation of
the language and locale (country) like "Klingon (Klinzhai)".
Then load the build/locales.json on your page into a locales variable and in Sucrose chart instantiation pass a locale object to set string/datetime/number formatting options:
var myLocale = locales['en_US'];
var chart = sucrose.chart.pieChart.locality(myLocale);The default formatters in the charts and models will now have localized content. For instance, the pieChart tooltip uses a format utility function:
var val = utility.numberFormat(y, 2, yIsCurrency, chart.locality());With locales['en_US'] the display string for 1234.567 as currency will be $1,234.57
while for locales['fr_FR'] the display string will be 1 234,57 €.
