# Sapphire
|
|
A modern, fast and reliable programming language. (WIP)
|
|
|
|
**WARNING**: Most features in this README (especially the About section) are planned for the future and not yet implemented.
|
|
|
|
## About
|
|
Sapphire is a relatively high-level programming language, yet low-level when it needs to be. The language supports low-level memory manipulation using pointers, but pointer arithmetic is only allowed in unsafe contexts, for greater memory safety. Dynamic memory allocation is also a thing, though it is recommended not to use it directly, but instead make great use of [smart pointers](https://en.wikipedia.org/wiki/Smart_pointer).
|
|
|
|
Sapphire is a [compiled](https://en.wikipedia.org/wiki/Compiled_language) programming language, with static typing, although [type inference](https://en.wikipedia.org/wiki/Type_inference) is also supported. It also has a high-level standard library, which supports console/file I/O, operating system functions, advanced math operations, string manipulation, and many more.
|
|
|
|
## Basic usage
|
|
"Hello world" in Sapphire:
|
|
|
|
```
|
|
const io from @'core/io';
|
|
|
|
let @main in {
|
|
io.outln('Hello, World!');
|
|
}
|
|
```
|
|
|
|
or alternatively:
|
|
|
|
```
|
|
const { outln } from @'core/io';
|
|
|
|
let @main in {
|
|
outln('Hello, World!');
|
|
}
|
|
```
|
|
|
|
## Examples
|
|
FizzBuzz:
|
|
```
|
|
const io from @'core/io';
|
|
const { toString } from @'core/type_utils';
|
|
|
|
let @fizzBuzz(i32 i) in {
|
|
String result = '';
|
|
if(i % 3 == 0)
|
|
{
|
|
if(i % 5 == 0)
|
|
{
|
|
result = 'FizzBuzz';
|
|
} else {
|
|
result = 'Fizz';
|
|
}
|
|
} else {
|
|
if(i % 5 == 0)
|
|
{
|
|
result = 'Buzz';
|
|
} else {
|
|
result = toString(i);
|
|
}
|
|
}
|
|
io.outln(result);
|
|
}
|
|
|
|
let @main in {
|
|
for(i32 i = 1; i <= 100; i++)
|
|
{
|
|
fizzBuzz(i);
|
|
}
|
|
}
|
|
```
|
|
Quine:
|
|
```
|
|
const io from @'core/io';
|
|
String fmt = 'const io from @%ccore/io%c;%cString fmt = %c%s%c;%clet @main in {%c%cio.outf(fmt,39,39,10,39,fmt,39,10,10,9,10,10);%c}%c';
|
|
let @main in {
|
|
io.outf(fmt,39,39,10,39,fmt,39,10,10,9,10,10);
|
|
}
|
|
