A Japanese language parser producing NLCST nodes.
- For semantics of nodes, see NLCST;
npm:
npm install parse-japanese

var ParseJapanese = require('parse-japanese')
var japanese = new ParseJapanese()
var text = '1 これは前段です。これは中段(2文の場合は後段。)です。これは後段です。\n'
japanese.parse(text, (cst) => {
console.log(inspect(cst))
})
