如何定义某个时间段的日历事件

Question

我改变了一些东西。

它的核心是一个键，我们可以控制条件（两个日期之间）和注释（Foo 或 Bar）。

这可以通过密钥完成

/tikz/if=(<cond>) <true> else <false>

其中<true>和<else>可以是[<style>]或，{<code>}并且else <false>部分是可选的。

为了排版注释，我使用了label远离xshift = 3.5em日期节点左侧但在基线（base west锚点）垂直对齐的注释。

由于日期重叠，我们不能仅仅使用，label=[<opts>]<dir>:#1因为这样我们会得到多个相互重叠的标签。

我已经进行了调整，day code以便当日记录尝试possible label使用来自的值collected labels（当它仍然可以访问时 - 这样做label=\pgfkeysvalueof{/tikz/collected label}是行不通的，因为节点选项在它们自己的组/范围内。

但是我们也不希望每个每天的节点都尝试设置标签，这就是为什么我们仅在我们的条件适用时才使用activate label设置键。possible label

关于条件，我使用了我图书馆的and钥匙ext.calendar-plistikz-ext包裹。
