# High Ground

High Ground is a programming language based on Ground.

It is the reference language designed to teach you how to build your own Ground-based language.

## Compiling

First, ensure CGround is installed on your system with `sudo make install`. Then, compile with

```
g++ src/main.cpp -o hg -lgroundvm
```

## Usage

High Ground files use the `.hg` extension. Run files as you would with any other interpreted language.

## Using High Ground

### Types

* `int`: Ground int (64 bit integer) eg 3, 7, 31432
* `double`: Ground double (Double precision floating point) eg 3.141, 2.7
* `string`: Ground string (char*) eg "Hello, World"
* `char`: Ground char (char) eg 'a'
* `bool`: Ground bool (either true or false)

### Printing

Prefix an expression with `puts` to print it to the console.

```
puts "Hello, world!"
puts 3.141
puts 7
puts 'a'
puts true
```

### Math

Add numbers with `+` (more operations coming soon)

```
puts 1 + 1
puts 3.14 + 2.7
puts 532 + 314 + 89432
```
