Go1.24: In addition to the standard library, you should probably pay more attention to changes in Go tools
Go 1.24 brings significant updates to its toolchain, streamlining dependency management, accelerating workflows, and catching bugs earlier. While language features often steal the spotlight, improvements to Go’s tools can dramatically impact developer productivity. Let’s break down two major areas: go tool and vet, with practical examples to

Go1.24: 除了标准库之外，您也许应该更加关注 Go 工具的变化
Go 1.24 引入了许多工具方面的重要更新，这些更新让开发者在管理依赖、调试问题以及编写更高质量代码时变得更加高效。尽管人们通常会将注意力集中在标准库或语言特性上的变化，但 Go 工具生态系统的改进同样值得关注。在本文中，我们将重点探讨两个关键领域的改进：go tool和vet工具，并通过实际示例展示这些更新如何优化你的工作流程。 Go 命令的增强功能 在 Go 1.24 中，go 命令进行了多项改进，使得依赖管理和工具执行更加高效且易于使用。其中最显著的变化之一是 go.mod 文件中新增了 tool 指令，允许你直接跟踪可执行工具依赖，而无需依赖诸如空导入等不直观的解决方案。 使用 Tool 指令跟踪可执行工具依赖 我们在项目中大量使用mockery[1]（一个流行的 Mock 代码生成器），使用方式是通过brew 安装或者直接下载特定版本的exe 执行文件。但是这样有个问题，如果不同开发者使用的mockery 版本不一致，会造成非预期的代码冲突。在过去，如果您想将这样的工具作为项目的一部分，
