不久前，我寻求一些帮助来找到一个简单的方法使用 TIkZ 绘制一些组件图。答案很棒，但是当将解决方案应用到我的情况时，我最终不得不多次复制粘贴相同的代码。
这是代码的一部分（没有全部复制粘贴的代码）。

样式ueast、uwest、unorth、usouth定义使用端口在其所连接的组件的每一侧进行绘制。样式peast、pwest、定义pnorthpsouth提供端口。并且有 4 种变体。
绘制黑色圆圈/半圆形的平面图。
绘制粗绿色圆圈/半圆圈的一个。
将三角形绘制为端口（不切成两半并旋转形状）。
画正方形的（不是切成两半的）。
因此，它有 8 种风格，有 4 种变体，从而形成了 32 种非常相似的 TIkZ 风格。
有没有办法更简洁地编写这些样式？可能不使用宏来生成代码。理想情况下，它会自动旋转端口。
如果需要的话，我可以包含缺失的代码。
答案1
代码已精简为四种样式xeast，xwest和xnorth，xsouth每种样式都有 6 个参数，一个后缀，可能的移位，颜色，边框旋转，端口类型和端口（长|中）-打开或关闭。所有原始样式只是这些新样式的一个特例。
更好的解决方案可能是尝试构建类似的东西，label但我不知道如何去做。
