nunjucks - 如何在帖子中使用nunjuck `include`？

Question

我在玩 hexo，我正在测试适用于小循环的 nunjuck 语法。但是我找不到如何include a file ，我的文件位置可能有误(目前在 /source/_posts 中的 .md 旁边)。

环境信息

目录结构

tree ./
./
├── include
│   └── colors.html
└── _posts
    └── button6.md

用法

npm install --save --only=prod hexo-include

在 button6.md 我添加了

{% include "include/colors.html" %}

错误

Unhandled rejection Template render error: (unknown path)
  Error: template not found: include/colors.html

提问

我在 _hexo-demo/source/posts/button6.md 中有这篇文章

---
title: button6
myitems:
  - one
  - two
---

{% for item in myitems %}
<li> {{ item }}</li>
{% endfor %}

<hr>
{% include "colors.html" %}

问题

我应该把我的 colors.html 文件放在哪里才能解析

Answer 1

我遇到了同样的问题。hexo-include 似乎与 numjack 冲突。我在下面更改了 lib/index.js

hexo.extend.tag.register('include_alt', include, {asyn: true});

但是还是不行。这可能是因为渲染时间。所以我在下面更改了 lib/index.js

var fs = require('hexo-fs');
var nunjucks = require('nunjucks');
var pathFn = require('path');
// hexo.extend.tag.register('include_alt', include, { asyn: true });
hexo.extend.tag.register('include_alt', function (args) {
  var path = pathFn.join(hexo.source_dir, args[0]);  
  return new Promise(function(resolve, reject) {
    nunjucks.render(path, function(err, res) {
      if (err) {
        return reject(err);
      }
      resolve(res);
    });
  });
}, {async: true});

然后我用它作为

{% include_alt 'some.html' %}

而且有效。
