hexo server 预览时改动 Markdown 后，刷新浏览器获取到的 HTML 内容不变

[songouyang]

Please make sure you took care of the following things before you submit this issue. Thank you!

• [x] I have set up and configured my blog according to the Hexo docs and the Icarus docs;
• [x] I have looked up Github issues and found no solutions to my problems.

默认主题不会出现此问题，用 icarus 主题就会有此问题。

主题版本：7b88a415d7deef50d2e02b510378d0ff332cdd6a

改成此版本 f5185d52d0723b3391e656f6b02a2b3e768d0fc9 即可获取到最新的 HTML 内容。猜测应该是这个 commit https://github.com/ppoffice/hexo-theme-icarus/commit/bdaab0f8fdd1794a8b41ec3f796755f6bb62d349 导致的。 把 LRU 的 size 改成 1 也可以使得 HTML 内容随着 Markdown 的变化而变化

@songouyang 缓存的HTML不会在修改源文件之后自动更新。这个在Hexo的代码中也有说明。所以这个问题是为了提升性能的一个牺牲。目前没有修复的计划。

我想了一個方法，就是在 hexo 的 filter.before_generate 中清除 __fragmentCache，當在 server 執行時，便可以在每次更改文件後重置一次 cache，應該不會太影響性能，請作為參考。

在 includes/helpers/override.js 中加入：

hexo.extend.filter.register('before_generate', function(){
    __fragmentCache.clear()
});
