# ethers-solc
Utilities for working with native `solc` and compiling projects.
To also compile contracts during `cargo build` (so that ethers `abigen!` can pull in updated abi automatically) you can configure a `ethers_solc::Project` in your `build.rs` file
First add `ethers-solc` to your cargo build-dependencies.
Once you compiled the project, you can configure cargo change detection with `rerun_if_sources_changed`, so that cargo will execute the `build.rs` file if a contract in the sources directory has changed
```toml
[build-dependencies]
ethers-solc = { git = "https://github.com/gakonst/ethers-rs" }
```
```rust
use ethers_solc::{Project, ProjectPathsConfig};
fn main() {
// configure the project with all its paths, solc, cache etc.
let project = Project::builder()
.paths(ProjectPathsConfig::hardhat(env!("CARGO_MANIFEST_DIR")).unwrap())
.build()
.unwrap();
let output = project.compile().unwrap();

// Tell Cargo that if a source file changes, to rerun this build script.
project.rerun_if_sources_changed();
}
```
