Foundry安装

最近安装了Foundry智能合约开发工具，遇到一些小问题，在这里记录一下解决的过程。
以下是windows下的安装流程，mac等环境原理类似。因为主要是要解决网络问题。
用的是官网推荐的使用foundryup的方式，源代码编译的方式嫌麻烦没实践。

网络问题

笔者用的是Clash Verge， 设置服务模式，再开启Tun模式即可。Tun模式开启后会生成虚拟网卡，这样不止浏览器、包括终端和后面用到的Git Bash等全部流量就都会走代理进行加速了。

安装Foundry

首先windows下面先安装Git Bash，然后运行：

$ curl -L https://foundry.paradigm.xyz | bash

然后根据提示，运行 source /c/Users/admin/.bashrc或者新开一个终端窗口。再运行：

$ foundryup

安装成功。

简单把玩一下

找个空文件夹，新建项目：

$ forge init hello_foundry
Initializing C:\Users\admin\foudrywork\hello_foundry...
Installing forge-std in C:/Users/admin/foudrywork/hello_foundry\lib\forge-std (url: Some("https://github.com/foundry-rs/forge-std"), tag: None)

warning: in the working copy of '.gitmodules', LF will be replaced by CRLF the next time Git touches it
    Installed forge-std v1.9.2
    Initialized forge project

这样就初始化建立了一个foundry项目hello_foundry，目录结构：

$ ls
README.md  foundry.toml  lib/  script/  src/  test/

然后构建，也就是编译：

$ forge build
[⠔] Compiling...
[⠒] Compiling 27 files with Solc 0.8.27
[⠑] Installing Solc version 0.8.27
[⠢] Successfully installed Solc 0.8.27
[⠆] Solc 0.8.27 finished in 5.43s
Compiler run successful!

然后是运行测试用例：

$ forge test
[⠊] Compiling...
No files changed, compilation skipped

Ran 2 tests for test/Counter.t.sol:CounterTest
[PASS] testFuzz_SetNumber(uint256) (runs: 256, μ: 31054, ~: 31288)
[PASS] test_Increment() (gas: 31303)
Suite result: ok. 2 passed; 0 failed; 0 skipped; finished in 12.71ms (11.85ms CPU time)

Ran 1 test suite in 15.24ms (12.71ms CPU time): 2 tests passed, 0 failed, 0 skipped (2 total tests)
