cntopo-typ

A modular set of CeTZ-powered computer network topology icons with Fletcher integration.

Overview

cntopo-typ is a collection of computer network topology icons, designed to be easy to use, extensible and work well with existing frameworks like CeTZ or Fletcher. The two main functions it provides are fletcher-shapes and icons, yielding all of the icons for use with Fletcher and CeTZ respectively. Both are parametarized the same way, as well as most of the icons in this package. All node icons are provided with 2d (flat: true) and 3d (flat: false) variants.

Usage

#import "@preview/cntopo:0.1.0": cetz, icons

#let ip = text.with(font: "FreeMono", weight: "bold")

#let (router, w-router, w-sec-router, cl-router) = icons(
  fill: blue,
  fill-inner: white,
  stroke-inner: white,
  stroke: blue.lighten(50%) + 2pt,
  flat: false,
)

#cetz.canvas(length: 4em, {
  router((0, 0), detail: "R1", label: ip[192.168.0.1])
  w-router((3, 0))
  w-sec-router((6, 0), label: ip[10.0.0.1])
  cl-router((9, 0))

  router((0, 2), detail: "R1", label: ip[192.168.0.1])
  router((3, 2), wireless: true)
  router((6, 2), wireless: true, detail: "secure", label: ip[10.0.0.1])
  router((9, 2), detail: "cloud")
})
