# Leafscript
Leafscript is a lightweight programming language created as a proof of concept by someone with no idea how to write a language.
It's written entirely in Golang, and was inspired by the speed and simplicity of Lua. It can be compiled from source to a binary .exe file using the command: ```go build Leafscipt```
## Usage
Programs can be run from the command line using the Leafscript binary file.
```leafscript --run [PATH TO .lfs FILE] --debug [SET TO FALSE BY DEFAULT]```
E.g.
```leafscript --run program.lfs```
Includes a basic debugger that prints a list of all variables every line. E.g.
```leafscript --run program.lfs --debug true```
## Features
It supports:
- Creating and modifying variables (strings, ints and floats)
- Performing mathematical operations on numeric variables
- String concatenation
- For loops
- If/else statements
- Breaks in for loops
- Nested if/for
- Basic debugging mode that prints all variables every line
No plans to implement in near future
- Array variables
- Error messages
## Examples
***Ensure tabs are used to indent and not spaces. Spaces do not work***
Additional language examples are contained within the "Examples" file
#### Find all the factors of a number
```
var number = inputint "Enter a number to find factors of: "
for x math number+1
if math number%x == 0
print concat math x & " is a factor of " & math number
endif
endfor
```
#### Print all binary numbers from 0 to 15
```
for x 2
for y 2
for z 2
for i 2
print concat math x & " " & math y & " " & math z & " " & math i
endfor
endfor
endfor
endfor
```
#### Print all primes up to a given number
```
var number = inputint "Enter a number to find primes up to: "
var total = 0
for x math number
var y = 0
for i math x
if math x%i == 0
var y = math y+1
endif
endfor
if math y < 2
print concat math x & " is prime"
var total = math total+1
endif
endfor
print concat math total & " primes found"
```
