# Mathpad

Mathpad is a small extension for [Visual Studio Code] that turns a Markdown editor into an interactive scratchpad calculator.

[![License](https://img.shields.io/github/license/sagebind/mathpad)](LICENSE)

[![Visual Studio Marketplace Version](https://img.shields.io/visual-studio-marketplace/v/sagebind.mathpad)](https://marketplace.visualstudio.com/items?itemName=sagebind.mathpad)

[![GitHub Workflow Status](https://img.shields.io/github/workflow/status/sagebind/mathpad/build)](https://github.com/sagebind/mathpad/actions)

I created this because I couldn't find a good notebook calculator that I liked that

- is free and open source,

- supports all the platforms I care about,

- works completely offline,

- supports variables and functions,

- allows you to edit anywhere (as opposed to REPL style),

- and works in and saves as plain text.

I already have [Visual Studio Code] installed on all my computers and use it for lots of text editing purposes, so I decided to make it also my calculator using this extension.

## Features

- Math expressions on their own line inside a Markdown editor are evaluated automatically and their results are displayed in grey at the end of the line.

- Variables can be defined on their own line like `x = 42` and referenced on any line below it.

- Functions can be defined on their own line like `f(x) = 42 / x` and referenced on any line below it.

- Changing a variable or function definition will automatically re-evaluate everywhere it is used in the rest of the document.

Much more is available as math expressions, which are powered by [Math.js]. Check out the Math.js documentation for even more examples of what sorts of expressions can be evaluated.

## Future ideas

There's a lot more neat ideas that _could_ be implemented, including:

- Defining our own language/editor type with dedicated math syntax highlighting.

- Evaluating expressions embedded in normal text.

- Replacing an expression with its result.
