发 issue 之前一定要先看文档！

几天前我刚换了博客的主题，给主题添加了一个让文章不在主页显示的功能，并往原作者的仓库提交了个 pull request 。

在这个过程中，我发现了一个 hugo 的 “bug” ，是关于 params 大小写的问题，具体的可以看前面的链接和后面的说明。总之我凭着自己敏锐的嗅觉发现了它，还准备往 hugo 那边发个 issue 。

然而当我废了半天劲写完这个 issue 时，猛地发现这可能不是 “bug” 而是 “feature” ，于是我赶紧去看了下文档。

Too young, too simple, sometimes naive ……

下面是我写好了差一点就发出去的 issue

就当是个教训啦

I’m using the newest hugo “Hugo Static Site Generator v0.37 windows/amd64 BuildDate: 2018-02-27T09:15:58Z”.

I downloaded a new theme and I try to hide some posts from the home page.

I try to use ‘hidden’ as a param to hide a post from the home page. And it did work.

This post is hidden from the home page.

But you can see it in archives, rss or other pages.

Then I try to use ‘hiddenFromHomePage’ instead of ‘hidden’. But it did not work.

But ‘hidden’ did work, so I think it might be something wrong with ‘hiddenFromHomePage’. I try to use ‘HIDDEN’ as the param, and it did not work too.

So I think it should be something wrong with lower/upper cases. I try to use ‘hidden’ in ‘index.html’ and ‘HIDDEN’ in markdown files… And it did work!

At last, I use ‘hiddenFromHomePage’ in the markdown files and ‘hiddenfromhomepage’ in the ‘index.html’ file. It might be something wrong with the params in lower/upper cases. https://github.com/olOwOlo/hugo-theme-even/commit/52777345e4db7693d665699346b86ffb25ae8077
