# Diesel Codegen Syntex
Provides the functionality of `diesel_codegen` using Syntex for usage on stable.
## Getting started
Add `diesel_codegen_syntex` to your `Cargo.toml`, specifying which backends you
use.
```toml
diesel_codegen_syntex = { version = "0.9.0", features = ["postgres"] }
```
Next, move the `mod` declarations of any modules that need codegen to a separate
file, such as `lib.in.rs`, like so:
```rust
// main.in.rs
mod schema;
mod models;
```
```rust
// main.rs
include!(concat!(env!("OUT_DIR"), "/main.rs"));
```
Finally, add a build file which calls `diesel_codgen_syntex::expand`
```rust
// build.rs
fn main() {
let out_dir = env::var("OUT_DIR").unwrap();
let src = Path::new("src/main.in.rs");
let dst = Path::new(&out_dir).join("main.rs");
diesel_codegen_syntex::expand(&src, &dst).unwrap();
}
```
For more examples, please see section 4 of the [getting started
guide](http://diesel.rs/guides/getting-started/)
