如何从Jekyll插件调用`handleize`液体过滤器？

Question

I must be off my game today because I can't even see where the handleize filter is even defined. It's in the Shopify documentation , and it works when I use it in my templates. However I can't see the source code for it, so I can't find out how to call it from my plugin.

Also note that while these two questions are similar, the answers do not apply here because handleize is not defined in either of the source modules mentioned.

If it matters, I'm using Jekyll 2.1.1 and Liquid 2.6.1.

Answer 1

对于其他任何偶然发现这一点的人， 从Jekyll版本2.4.0开始 ，你可以使用内置的slugify过滤器 ，它基本上可以执行handleize 。

Answer 2

OK turns out that the Shopify documentation is not correct; some of the documented filters, including handleize are not available from within a standard Jekyll install. The Jekyll core team is aware of the documentation issues and is working towards fixing them.

Also note that liquid does not seem to flag any errors or warnings when using an unknown filter. Hence you may (as I did) think that the filter "works" when in fact it is silently being ignored.

Answer 3

这是我无法使用handleize的工作：

{{ post.title | replace: ' ', '_' }}

Answer 4

To also get the downcased result:

{{ post.title | replace: ' ', '_' | downcase }}

or simply

{{ post.title | slugify }}
