1.4 一个Forc项目 (A Forc Project)

To initialize a new project with Forc, use forc new: 要使用 Forc 初始化新项目，请使用forc new：

forc new my-fuel-project

Here is the project that Forc has initialized: 这是 Forc 初始化的项目(目录)：

$ cd my-fuel-project
$ tree .
├── Forc.toml
└── src
    └── main.sw

Forc.toml is the manifest file (similar to Cargo.toml for Cargo or package.json for Node), and defines project metadata such as the project name and dependencies.

Forc.toml 是 manifest 文件（类似于 Cargo 的Cargo.toml 或 Node 的package.json），并定义项目的元数据，例如项目名称和依赖。

For additional information on dependency management, see: here. 有关依赖管理的其他信息，请参阅：此处。

[project]
authors = ["User"]
entry = "main.sw"
license = "Apache-2.0"
name = "my-fuel-project"

[dependencies]

Here are the contents of the only Sway file in the project, and the main entry point, src/main.sw: 以下是项目中唯一的 Sway 文件以及主要入口点 src/main.sw 的内容：

contract;

abi MyContract {
    fn test_function() -> bool;
}

impl MyContract for Contract {
    fn test_function() -> bool {
        true
    }
}

The project is a contract, one of four different project types. For additional information on different project types, see here.

该项目是一个 合约，是四种不同项目类型之一。有关不同项目类型的更多信息，请参阅此处。

We now compile our project with forc build, passing the flag --print-finalized-asm to view the generated assembly:

我们现在使用forc build编译我们的项目，传递标志--print-finalized-asm以查看生成的程序合集：

$ forc build --print-finalized-asm
...
.program:
