A blazingly fast alternative to [CosmWasm/rust-optimizer] for compiling & optimizing CW smart contracts.

It's primarily meant to speed up local development and testing.

### Features:

- **Fast** - especially in workspaces with many contracts
- Uses same optimizations as `rust-optimizer` by default
- No dependency on Docker
- Supports both single- & multi-contract workspaces
- Written as a [cargo subcommand]
- Cross-platform, cross-arch

### Installation

```sh
# Pre-requisites
$ rustup install 1.69.0
$ rustup target add wasm32-unknown-unknown

$ cargo install cw-optimizoor
```

You might also need any of the following:

#### Linux
```sh
# Ubuntu
$ sudo apt install -y cmake pkg-config libssl-dev clang

# Fedora
$ sudo dnf install -y cmake openssl-devel clang
```

#### macOS
```sh
$ xcode-select --install # clang
$ brew install cmake pkg-config
```

#### Windows
- [Visual Studio C++, Clang & Build Tools]
- [CMake]
- [Python]

### Usage

```sh
$ cargo cw-optimizoor -h

Usage: cargo cw-optimizoor [OPTIONS] [WORKSPACE_PATH]

Arguments:
  [WORKSPACE_PATH]  Path to the workspace dir or Cargo.toml

Options:
  -f, --features <FEATURES>  Space or comma separated list of features to activate
      --all-features         Activate all available features
      --no-default-features  Do not activate the `default` feature
  -h, --help                 Print help information
  -V, --version              Print version information
```

### Example
```sh
$ cargo cw-optimizoor              # defaults to the current dir
# cargo cw-optimizoor Cargo.toml   # or this for pointing directly at a Cargo manifest
# cargo cw-optimizoor .            # or this for the current dir
