jekyll - 获取 Jekyll 中两个日期之间的天数差

Question

我想获得 Jekyll 中两个日期之间的天数差异。我怎样才能做到这一点？

{% capture currentDate %}{{ site.time | date: '%Y-%m-%d' }}{% endcapture %}
{{currentDate}}
{% capture event_date %}{{ entry.date }}{% endcapture %}
{% if event_date < currentDate %}Yes{% else %}No{% endif %}

在条目中有我的 YAML:

---
title: ChartLine C3
type: charts
description: Chart with round for prisma
id: c3-1
date: 2015-07-18
---

在 Liquid(Jekyll 的模板引擎)中执行此操作的方法很愚蠢:

{%   assign today = site.time | date: '%s'      %}
{%   assign start = '20-01-2014 04:00:00' | date: '%s'  %}
{%   assign secondsSince = today | minus: start     %}
{%   assign hoursSince = secondsSince | divided_by: 60 | divided_by: 60     %}
{%   assign daysSince = hoursSince | divided_by: 24  %}

Hours: {{hoursSince}}
Days: {{daysSince}}

Hours: 27780

Days: 1157

请注意，Liquid 的 divide_by操作自动循环。

Remainder hours: {{hoursSince | modulo: 24}}

Remainder hours: 12

如果这让你和我一样恼火，那么你可以这样做来恢复小数位:

{%   assign k = 10   %}
{%   assign divisor = 24   %}
{%   assign modulus = hoursSince | modulo: 24 | times: k | divided_by: divisor  %}
{{daysSince}}.{{modulus}}

1157.5

向 k 添加更多零添加更多小数位。
