CalcMark for VS Code

Language support for CalcMark — calculations and markdown in one document.

Features

• Syntax highlighting — TextMate grammar for .cm and .calcmark files
• Diagnostics — errors and warnings with precise source positions
• Autocomplete — functions, units, variables, natural-language syntax
• Hover — variable values, function signatures, unit descriptions
• Go-to-definition — jump to variable assignment
• Document symbols — variables and headings in outline view
• Code actions — quick fixes for undefined variables
• Signature help — parameter hints inside function calls
• Semantic highlighting — context-aware calc vs markdown line classification
• Live preview — rendered document in a side panel, updates on every keystroke

Requirements

The cm binary must be installed and on your PATH.

brew install calcmark/tap/calcmark

Or download from GitHub Releases.

Usage

1. Open any .cm or .calcmark file
2. Cmd+Shift+P → CalcMark: Open Preview for live rendered preview

To use a specific cm binary, set calcmark.binaryPath in settings.

Codespaces
