Kalker Kalker

calculator math rust rust-crate
Use this command to install Kalker:
winget install --id=PaddiM8.kalker -e

Kalker is a calculator program that supports user-defined variables, functions, derivation, and integration.

Kalker is a scientific calculator program designed to perform advanced mathematical computations with support for user-defined variables, functions, differentiation, and integration.

Key Features:

  • Support for complex mathematical operations, including derivatives, integrals, and root finding using Newton's method.
  • Ability to define custom functions and variables, enabling users to create tailored calculations.
  • Syntax highlighting and special-symbol completion on tab (e.g., converting "sqrt" to √).
  • Cross-platform compatibility, running on Windows, macOS, Linux, Android, and web browsers via WebAssembly.
  • Integration with package managers like winget for easy installation.

Audience & Benefit:
Ideal for students, researchers, engineers, and anyone requiring precise mathematical computations. Kalker streamlines complex calculations, reduces errors, and enhances productivity by providing a flexible and intuitive toolset for advanced mathematics.

README

Kalker is a calculator program/website that supports user-defined variables, functions, differentiation, and integration. It runs on Windows, macOS, Linux, Android, and in web browsers (with WebAssembly).

Features

  • Operators: +, -, *, /, !
  • Groups: (), [], ⌈ceil⌉, ⌊floor⌋
  • Vectors: (x, y, z, ...)
  • Matrices: [x, y, z; a, b, c; ...]
  • Pre-defined functions and constants
  • User-defined functions and variables. f(x, y) = xy, x = 5
  • Root finding using Newton's method (eg. x^2 = 64). Note: estimation and limited to one root
  • Derivative of functions (derivatives of noisy functions or of higher order can be a bit inaccurate). f'(2), sin'(-pi)
  • Integration. ∫(0, pi, sin(x) dx) or ∫(0, π, sin(x) dx), maybe sometimes be slightly off
  • Understands fairly ambiguous syntax. Eg. 2sin50 + 2xy
  • Syntax highlighting
  • Special-symbol completion on tab. Eg. write sqrt and press tab. It will be turned into √
  • Sum function: sum(start, to, expression) Eg. sum(1, 3, 2n+1) is the same as 2*1+1 + 2*2+1 + 2*3+1 = 15
  • Piecewise functions: f(x) = { f(x + 1) if x <= 1; x otherwise }, pressing enter before typing the final } will make a new line without submitting

  • Load a file including predefined functions and constants. For example, if you're going to use kalker for physics, you load up your file with physics functions/constants when starting kalker. This is done either using the -i file flag or by putting files in a certain directory and then doing load filename inside kalker. More about files here
  • Different number bases: Either with a format like 0b1101, 0o5.3, 0xff or a format like 1101_2. The latter does not support letters, as they would be interpreted as variables
  • Misc: separate expressions by a semicolon to write them on the same line, use the ans variable to get the value of the previously calculated expression

    • Installation

    Package managers

    macOS (Homebrew)

    brew install kalker

    macOS (MacPorts)

    sudo port install kalker (info)

    Arch Linux

    kalker in the AUR, eg. yay -S kalker

    Nix/NixOS

    kalker in the nixpkgs repository. The most up to date version is also available as a flake.

    NetBSD

    pkgin install kalker (from the official repositories)

    Binaries

    Pre-compiled binaries for Linux, Windows, and macOS (64-bit) are available in the releases page.

    Compiling

    Minimum rust version: v1.36.0. Make sure you have diffutils gcc make and m4 installed. If you use windows: follow the instructions here (don't forget to install mingw-w64-x86_64-rust in MSYS2).

    Cargo

    Run cargo install kalker

    Manually

    1. Go into the cli directory.
    2. Run cargo build --release
    3. Grab the binary from targets/release

    Libraries

    There are currently three different libraries related to kalker.

    • kalk: The Rust crate that powers it all.
    • @paddim8/kalk: JavaScript bindings for kalk. This lets you use it in the browser thanks to WebAssembly.
    • @paddim8/kalk-component: A web component that runs @paddim8/kalk, which let's you use kalk in the browser with a command line-like interface.

    Syntax

    A complete reference can be found on the website.

    Contributing

    kalk and cli (Rust)

    After making changes to the kalk library (in kalk/), you can easily try them out by going to the root of the project directory, and doing cargo run. This will start kalker (cli), with the new changes. If you're using Windows, you will need to follow the instructions here, but also make sure to install mingw-w64-x86_64-rust in MSYS2.

    All Rust code is expected to be formatted with `rustfmt

    web (Svelte, TypeScript, Sass)

    Run:

    1. npm install
    2. npm run dev - this will automatically re-compile the project when changes are made

    mobile (Android)

    Run:

    1. npm install
    2. npm run build
    3. npx cap sync
    4. Build the project using Android Studio, or Gradle directly.
