## 2. Setting Up Your Cargo Project
|
||||
|
||||
Mist works alongside Cargo to handle the heavy lifting. Use `cargo new` or `cargo init` to scaffold a new project:
|
||||
|
||||
```bash title="Terminal"
|
||||
cargo new my-mist-app
|
||||
cd my-mist-app
|
||||
## 2. Setting Up Your Mist Project
|
||||
```bash
|
||||
mist new mist-hello-world
|
||||
```
|
||||
or
|
||||
```bash
|
||||
mist init
|
||||
```
|
||||
|
||||
This creates a `src/main.mist` and wires up the output directory (`.mist/src/`) in your `Cargo.toml`.
|
||||
|
||||
### 3. Adding mist to your Cargo project
|
||||
|
||||
Mist needs a `Mist.toml` in the root of the project (Alongside `Cargo.toml`) to know what to transpile as the main file (eg. main.mist, lib.mist).
|
||||
|
||||
```toml title="Mist.toml"
|
||||
# main.mist is now the main package
|
||||
package = "main.mist"
|
||||
|
||||
# Side packages that work as cargo binaries
|
||||
packages = []
|
||||
```
|
||||
|
||||
Source files go in `src/` and the transpiled output goes to `.mist/src/`. Non-Mist files in `src/` (e.g. Rust sidecar files) are copied through as-is.

|
||||
|
||||
Mist is meant to feel like C++ but **be** Rust. It bridges the gap between the ergonomics of a classic systems language and the safety guarantees of Rust's ownership model.
|
||||
|
||||
### Type-First Syntax
|
||||
|
||||
Low-level and embedded development demands clarity about what your data is. Mist puts the **type first** — before the name — so declarations read naturally:
|
||||
|
||||
```mist
|
||||
i32 score = 100;
|
||||
Vec<String> args = env::args().collect();
|
||||
void* data = allocate(size);
|
||||
```
|
||||
|
||||
This mirrors C/C++ declaration syntax, making Mist instantly familiar to embedded and systems programmers while compiling into Rust's strict type system.
|
||||
|
||||
### C-Style Functions
|
||||
|
||||
Functions use the return type before the name — no `fn` keyword needed:
|
||||
|
||||
```mist
|
||||
i32 add(i32 a, i32 b) {
|
||||
a + b
|
||||
}
|
||||
|
||||
void log(message *str) {
|
||||
println!("{}", message);
|
||||
}
|
||||
```
|
||||
|
||||
Every function maps directly to a Rust `fn` underneath.
|
||||
|
||||
### Minimal Friction
|
||||
|
||||
* No `let` keyword — `Type name = value` is all you need.
|
||||
* Consistent `name Type` convention across parameters, fields, and locals.
|
||||
* Explicit pointers with `*T` and `*mut T` — clear intent without ceremony.
|
||||
* String references use `str&` for a natural left-to-right read.

## Built for Low-Level and Embedded
|
||||
|
||||
Mist is designed from the ground up for systems where resources are constrained and control is required:
|
||||
|
||||
* **No runtime** — no garbage collector, no hidden allocator, no VM.
|
||||
* **Direct memory control** — explicit pointers, manual allocation, predictable layout.
|
||||
* **Zero-cost abstractions** — classes, traits, and generics all resolve at compile time.
|
||||
* **Works with existing Cargo tooling** — use any Rust crate as a library.

## Bootstrapped Development

Mist is partially bootstrapped — the compiler's CLI, transpiler, and analyzer modules are written in Mist itself. This gives us first-hand experience with the language's ergonomics and drives real-world improvements with every release.
