Hugo lunr zh

Generate lunr.js index file for hugo static site with Chinese support.

Install

globally:

npm install -g hugo-lunr-zh

or as a dev dependence:

npm install -D hugo-lunr-zh

Usage

your can use it in command line:

hugo-lunr-zh  -o docs/lunr.json --matter-delims --- --matter-type yaml

or run it in file:

const lunr = require("hugo-lunr-zh");
lunr({
  output: "docs/index.json"
}).then(() => {
  console.log("done");
});

after generating the index file, you need extend the lunr object with a new trimmer on the browser side:

lunr.zh = function() {
  this.pipeline.reset();
  this.pipeline.add(lunr.zh.trimmer, lunr.stopWordFilter, lunr.stemmer);
};

lunr.zh.trimmer = function(token) {
  return token.update(str => {
    if (/[\u4E00-\u9FA5\uF900-\uFA2D]/.test(str)) return str;
    return str.replace(/^\W+/, "").replace(/\W+$/, "");
  });
};
 
lunr.Pipeline.registerFunction(lunr.zh.trimmer, "trimmer-zh");
 
//...
const index = lunr(function() {
  this.use(lunr.zh);
  //...
});
