schemgo

Let the gophers put your schematic to paper!

Note

This tool is under active development and is not currently in a usable state. Stay tuned!

❓ What is this?

A command line utility that generates circuit schematic diagrams from code. Think Schemdraw or circuitikz, but simpler and faster!

Why choose this over Schemdraw/circuitikz?

• Is a self-contained binary.
• Is blazingly fast.
• Is easily included in mdbook as a preprocessor

🌱 Quickstart

go install github.com/sermuns/schemgo

Many other installation methods are supported!

💡 A simple example

Create a file simple.schemgo containing:

battery.right
line.up
resistor.left
line.down

Run:

schemgo build simple.schemgo -o simple.svg

The circuit diagram is created as simple.svg:

Note

Only svg output is supported at the moment.

🗺️ Roadmap

✔️ Done

• Push and pop
• Subcommands
  • build exports svg file
  • serve serves a development website for live-preview
• Comments with #
• mdBook preprocessor

🔴 High priority

• Labels
  • typst math
• multiple terminal: named anchors on components?

🟡 Normal priority

• Components (I won't attempt before situation with polymorphsim is under control.)
  • Optional style string on tags
  • (Better way of defining appearances... maybe external files?)
  • More components
    • Battery
    • Resistor
    • Inductors
    • Capacitor
    • Node (dot)
    • Voltage source
    • Current source
    • Diodes
    • Transistors
    • Amperemeter
    • Voltmeter
    • Switch
    • GND (and 5V)?
• @set statement to change global defaults (stroke width, padding, color)
• set standard (IEC, IEEE) on elemnt, using set
• Element attributes
  • ID for symbolic reference
• Exporting to pdf, png, jpg, webp
• Syntax highlighting, LSP
• Logic gates
