如何导入 iCal 格式并在 Tikz 中制作时间表？

Question 1

我编写了一个简短的 Python 脚本和一个 Jinja 模板，尝试自动生成您需要的时间表。以下是正在进行的工作：

在继续之前，我可以检查一下时间是否正确吗？我不确定我是否正确处理了日期和时间：特别是周四量子化学和电磁场理论之间似乎有重叠。

作为参考，这里是当前的 Python 代码：

#generate_tikz.py
'''Requirements:
arrow for datetime handling
ics package for reading ICS file,
jinja2 for the templating'''

import arrow
from ics import Calendar
from jinja2 import Environment, FileSystemLoader
from collections import Counter

with open('cal.ics', 'rt') as f:
    cal = Calendar(iter(f))

env = Environment(loader=FileSystemLoader('.'))
template = env.get_template('cal.tpl')

days = [dict() for i in range(5)] 
for event in cal.events:
    day = event.begin.weekday()
    if day >= 5: #weekend
        continue
    days[day][event.begin.hour] = event

from pprint import pprint
pprint(days)

names = Counter(event.name for day in days for event in day.values() )
names = [x[0] for x in names.most_common()]
colors = ['red', 'green', 'blue', 'orange', 'purple', 'brown', 'gray']

with open("cal.tex", "wt") as f:
    f.write(template.render(
        days=days, names=zip(names, colors)
    ))

这是 Jinja 模板：

如果您的系统上装有最新版本的 Python，则可以用以下命令安装所需的软件包：pip install ics jinja2 然后使用以下命令运行脚本：python generate_tikz.py 最后，调用 pdflatex cal.tex 生成 pdf。

如果您无法在您的系统上执行此操作，我在下面提供了输出 TeX 代码。

Question 2

我贡献了一种使用纯 TikZ 绘制时间表的简单方法。

为什么说这个代码简单呢？因为基本上它只是从缩放网格开始

\begin{tikzpicture}[xscale=4,yscale=1]
\draw (0,0) grid (5,-5);
\end{tikzpicture}

node然后，每对时间/工作都用一个颜色框和一个（容易心算的）点来绘制

\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}[xscale=4,yscale=1]
\draw (0,0) grid (5,-5);

\draw[fill=cyan!20] (1,-2) rectangle +(1,-3);
\path (1.5,-3.5) node[align=center]
{\bfseries ODEs MAT2314\\
    Room 204T4\\
    \itshape Pedagogic Math\\
    Dept. of Maths};
\end{tikzpicture}
\end{document}

下午的时间与早上的时间相似，只是时间偏移了(0,-6)。

完整代码如下。

\documentclass[tikz,border=5mm]{standalone}

% Morning
\begin{scope}
