doodledigits's Introduction

Doodle Digits

Doodle Digits is an inline calculator where you write equations into a large textbox and the answers are given to you as you type.
This approach lets you easily go back and change things in your equation and is easy and intuitive to use.

Features

Variables that can hold values
Arbitrary precision numbers allow you to calculate very large numbers, some high limits are put in for performance reasons
Autosaving that quickly lets you go back to where you were
A large library of math functions
Bitwise operations (keywords are bxor, bor and band to not clash with some other math notations)
Hex and binary numbers (0xE32C2C, 0b10)
Vectors and matrices (x = (1, 2), det [[3, 4], [5, 6]])

Download and Install

Downloads and installation instructions can be found on the releases page.

Doodle Digits as a library

You can use the Doodle Digits math core as a standalone math library for C#. The nuget package can be found here.

using DoodleDigits.Core;

// Create a new calculator. The default constructor will use the functions inside FunctionLibrary.Functions and ConstantLibary.Constants.
// You can implement custom functions and constants using the Calculator(IEnumerable<FunctionData> functions, IEnumerable<Constant> constants) constructor.
var calculator = new Calculator();

// Calculate the input
var result = calculator.Calculate("5 + 5");

// Find the result with a value. A calculation can return multiple results, including error messages and hints. The ResultValue is the result of a calculation.
var resultValue = result.Results.OfType<ResultValue>().LastOrDefault();

Contributing

As in most projects, make sure whatever you submit is unit tested if necessary and that all tests pass.
Commits with emoji are preferred. I try to stay on the latest version of C# and .NET because it's nice.

doodledigits's Issues

🌐 Localization support

Maybe with spplt?

👩‍💻 Hex and binary output

Right now, hex and binary literals are parsed, but doing anything with them will make the result in decimal notation. It should stay in the same format it started. Also there should be a way to move between presentations. I suggest using the keywords as/in like this:
25 in hex = 0x1B
25 - 1 as hex = 0x1A
0xB in decimal = 11
0xBA = 0xBA
4 in binary = 0b100

💾 User defined functions

Example syntax:

f(x) = x + 5
f(5) = 10

Annoying bit is not colliding with existing syntax of f times x equals something.
Since
f = 5
x = 1
f(x) = x+4 -> true

I'm thinking it's parsed as a function in the AST and if the function name is defined already the calculate function will run multiplication instead.

📐degree mode for trig functions

I would like degree mode because radians are confusing.

ℹ Help page

There's a lot of behavior inside the app which is not explained anywhere. Users are unlikely to discover these by guessing, such as the keywords for bitwise operators.
It'd be good to have some sort of lexicon with all kinds of operations and functions along with a short description.

1️⃣ When the first line is blank, the results of the equations is off by 1 line

This bug does not occur when there are any characters on the first line (including spaces).

📐 Additional trig functions

cotangent, secant and cosecant as well as their inverse are not added.

👻 Imaginary numbers

Support for i, and all the wonderful expanded function declarations that entails.

#️⃣ Add commenting

Let me explain things to me, myself, or friends through text inside the application. It should also have a nice color. :-)
You'd presumably start a comment with a symbol not used in math. But // should be fine I guess. Otherwise, ;, # or maybe \.

🅰When scrolling all the way to the right, the text is cut off slightly

Steps to reproduce:

Make the window the smallest it can be on the horizontal axis
Enter an expression that exceeds the width of the window (such as 1+1+1+1+1)
Scroll all the way to the right

💙 ____ There is no yellow color scheme.

Or any other scheme. What the heck. Let me set my background as a frog, damn it!

🧮Ceiling(x) doesn't round up

Ceil() or Ceiling() actually rounds to the nearest value instead of rounding up.

🔝 Always on top window option

make an option for the window to always be on top plz or jacob will cry

🔤Allow the font size to be adjustable

This could be controlled by doing ctrl + and ctrl - and added to the right click menu.

⚙ Settings page

A settings page for the calculator.
Example settings:

Autosave Interval
Show grid
Use degrees/radians
Font family - size - color
- Not sure how this would play with #2 when it comes to color.

🖼 Make a new icon

I'll miss the old one, but I think we can do better.

🌃 Dark mode

A toggle between a light and dark mode would be nice.

📐 Vector support

Allow calculations with vectors.

Declaring a 1d vector:
vec = [0, 1]

Declaring a 2d vector:
vec = [ [0, 1], [2, 3] ]

etc.

Probably wont support any operators with them other than obvious ones. Adding norm (||) would clash with boolean or. (although technically since one is unary we can work out the order)
(might revisit it then)
