mini-repl

Miniamal REPL written in C

Building

Available Makefile with make start which builds using gcc on macOS nad Linux

make start

Basic usage

mini-repl uses inifx notation as well as functions

> 42
42.00
> 2 + 2
4.00
> 10 - 1
9.00
> 2 * 3
6.00
> 2/2
1.00

It also has support for floating point value

> 2.1 + 2.1
4.20

Functions

Functions are reprezented as function(a,b). One argument function has to have trailing coma after argument. It's not forbidden with more than one argument.

Available functions

• add(a, b)
• subtract(a, b)
• multiply(a, b)
• divide(a, b)
• absolute(a)
• neg(a)
• factorial(a)
• sin(a)
• cos(x)
• tangent(x)
• cotangent(x)
• pi - takes no arguments and returns PI
• fromdec(number, base) - returns decimal value in specified base
• todec(number, base) - returns decimal value
• grey(number, base) - returns binary number in Grey code

Negative values

mini-repl do not understand negative values as for example -1. You have to use neg(a) function to negate given value

Variables

mini-repl has basic support for variables. To define variable is let variable = value. Value can be any expresion. To use specified value use: @variable.

> let a = 1
> @a
1.00
> @a + 2
3.00
> let b = @a + 3
> @b
5.00
> let c = factorial(@b,)
> @c
120.00
