Plankalkül for Visual Studio Code
Language support for Plankalkül, the world's first high-level programming language, designed by Konrad Zuse in 1945.
Features
- Syntax Highlighting for both linear (
.pk) and 2D notation (.pk2d)
- 2D Notation Editor - edit Plankalkül in Zuse's original tabular format with V/K/S rows
- Language Server Protocol - diagnostics, hover info, and go-to-definition
- Compile to C - generate executable C code from Plankalkül source
File Types
| Extension |
Description |
.pk |
Linear notation (modern readable format) |
.pk2d |
2D tabular notation (Zuse's original format) |
2D Notation
Zuse wrote Plankalkül in a unique 2D tabular format where each expression spans multiple lines:
| | V0 + V1 | => | R0 |
| V | 0 1 | | 0 |
| K | | | |
| S | 1.n 1.n| | 1.n|
The extension includes a custom 2D editor that renders this notation properly.
Commands
Plankalkül: Compile to C - Generate C code from the current filePlankalkül: Show 2D Preview - Preview linear notation as 2DPlankalkül: Convert to 2D Notation - Convert .pk to .pk2dPlankalkül: Convert to Linear Notation - Convert .pk2d to .pk

About Plankalkül
Plankalkül ("Plan Calculus") was designed by German engineer Konrad Zuse between 1942-1945. It included advanced features like:
- Structured data types (including nested records)
- Array operations with component access
- Logical quantifiers (for-all, exists)
- Iterators and filters
- Chess programs (ZIA-0367, ZIA-0368)
The language was never implemented during Zuse's lifetime. This project brings it to life 80 years later.
