我如何动态地在Jekyll _config.yml中更改变量？ [英] How can I change a variable in Jekyll _config.yml dynamically?

问题描述

您好我正在开发一个Jekyll项目，我需要在_config.yml中添加一个变量，以便从模板代码中动态更改。

Hi I'm working on a Jekyll project and I need to put a variable in _config.yml that I want to change dynamically from the template code.

是我想要做的，但我无法让它工作。是否有可能这样做？

This is what I want to do, but I can't get it to work. Is it possible to do this?

在_config.yml中：

In _config.yml:

my_var: "value"

在template.html中：

In template.html:

{% site.my_var = "newvalue" %}

{% case site.my_var %}
  {% when "value" %}
    //do this
  {% when "newvalue" %}
   //do this instead
{% endcase %}

推荐答案

虽然您显然无法使用和环境变量（和许多其他构建脚本一样），您可以使用第二个yml文件进行选择性覆盖：

While you apparently cannot use Liquid conditionals nor Environment Variables (as in many other build scripts), you can do a selective overrides with a second yml file:

$> bundle exec jekyll serve --drafts --incremental --config _config.yml,_dev.yml

用 _dev.yml ：

# overrides title in _config.yml
title: "My Website (dev mode)"

# see my styles uncompressed for dev work
sass:
    style: uncompressed

也许这符合您的需求......

Perhaps that fits your needs...
