Johnny Boursiquot 介绍了嘉宾 Qi Xiao,他使用 Go 语言编写了一个名为 Elvish 的 shell 程序。Qi Xiao 解释了创建 Elvish 的原因,是因为现有 shell 的局限性以及他对编程语言和用户界面的兴趣。Elvish 的主要优势在于其真正的编程语言特性和便捷的 UI 功能,例如内置的文件管理器和改进的命令历史搜索。Elvish 既包含内置命令,也依赖外部命令,但内置命令更偏向编程语言风格。Qi Xiao 还分享了他选择 Go 语言进行开发的原因,Go 丰富的标准库和自带的垃圾回收机制简化了开发过程。尽管 Go 语言的一些特性,例如缺乏真正的枚举和标签联合、没有关键字参数和默认参数,使得库的 API 设计不够简洁,但总体而言,Go 语言非常适合 Elvish 的开发。Elvish 的未来发展方向包括开发新的 TUI 框架以及更紧密地集成 shell 和终端。 Qi Xiao 认为现有的 shell 程序存在一些局限性,例如 Bash 的语法晦涩难懂,Zsh 的 UI 功能不够完善。他希望创建一个兼具编程语言的灵活性和良好用户界面的 shell 程序。Elvish 的设计理念是提供真正的编程语言特性,例如列表、映射、lambda 表达式等,以及便捷的 UI 功能,例如内置的文件管理器和改进的命令历史搜索。选择 Go 语言进行开发是因为 Go 拥有丰富的标准库、高效的性能和自带的垃圾回收机制。虽然 Go 语言的一些特性,例如缺乏真正的枚举和标签联合、没有关键字参数和默认参数,使得库的 API 设计不够简洁,但总体而言,Go 语言非常适合 Elvish 的开发。Elvish 的未来发展方向包括开发新的 TUI 框架以及更紧密地集成 shell 和终端。
