Wire Lang documentation

Wire Lang is a text-first language for electronic schematics. You describe a circuit as components, terminals, and nets in a small declarative .wire file, and Wire Lang renders it as a clean, documentation-ready SVG. The same source always produces the same diagram.

Code is text, so AI can read it, write it, and refactor it. Diagrams followed with text formats like Mermaid. Electronic schematics never made that jump and stayed locked inside GUI editors that AI cannot read. Wire Lang is the missing layer between AI and the circuit board: schematics become something an engineer or an assistant can generate, review, and improve as plain text.

Wire Lang is a documentation-oriented schematic renderer. It models a real electrical circuit — components with typed terminals joined by nets — rather than flowchart boxes and arrows. It is not a simulator, a PCB layout tool, a breadboard tool, or a BOM manager.

The shortest example

A 5 V battery drives a red LED through a 220 ohm current-limiting resistor. This is a complete, valid Wire Lang document: 

schematic
  title "LED current limiting circuit"

  component BT1 Battery voltage=5V
  component R1 Resistor value=220ohm
  component D1 LED color=red

  net VCC: BT1.+, R1.1
  connect R1.2, D1.A
  net GND: D1.C, BT1.-

  annotation "Current limiting resistor" near R1
