本周,我有机会深入研究如何使用 git rebase,同时重构我的 VShell 工具的代码库。我的主要任务是改进代码的结构和可维护性,同时遵守 DRY(不要重复自己)原则,这对于使代码更具可读性、可维护性和更易于调试至关重要。此外,我遵循了重构目录中概述的各种重构模式,例如提取函数、提取类和重命名变量。
在深入探讨我的重构工作的细节之前,我将为仍在熟悉这个强大的 Git 功能的开发人员提供 git rebase 过程的概述。
Git 变基概述
基本命令:
-
git rebase
:此命令将当前分支的提交移动到指定分支的顶部,从而有效地重新确定当前分支的基础。 git rebase
; :此命令将主题分支重新设置为基础分支,而无需先检出主题分支。
示例:通常,您会检查主题分支并运行 git rebase,但此命令允许在保留基础分支的同时进行变基。
冲突处理:
- git rebase --abort:取消 rebase 并将分支恢复到之前的状态。
-
git add
:解决合并冲突后将已解决的冲突添加到暂存区。 - git rebase --continue:冲突解决后继续 rebase 过程。
交互式变基:
- 使用 git rebase -i
;用于将多个提交压缩为一个。 - 成功变基后,可以删除主题分支,因为所有更改都已集成。使用 gitbranch -d
;删除分支。
重要提示::
- 避免主分支变基,因为它会影响其他协作者。
- 仅在您的主题分支上重新建立基础,以便在推送之前清理您的工作。
→ 在推动清理工作之前重新调整本地更改的基础,但切勿重新调整已推送到某处的任何内容。
重构过程
创建重构分支
为了防止破坏当前工作代码,我基于主分支创建了一个单独的重构分支。这使我能够安全地尝试更改。-
分析和重构代码
尽管我最初将模块化模式应用于 VShell 代码,但仍需要进一步改进以拆分更大的模块并创建更具可读性的代码流。-
源代码/服务器:
- 我将重复的日志记录逻辑重构为handleDebugMessage() 函数,允许通过stderr 流进行集中日志记录。
- 我还在 ConfigHandler.js 中创建了一个新的 ConfigHandler 类来处理配置 .toml 文件处理。 getTomlFiles() 和 loadConfig() 方法被封装到此类中,用于设置的模块化处理。
-
源代码/服务器:
-
ai_config/grogConfig.js:
- 从 chatCompletion AI 返回响应的两种方法在令牌使用检索中存在重复。我将此逻辑提取到 getTokenUsage() 函数中,允许 readStream() 和 PromptGroq() 重用它。
- 此外,我修复了 PromptGroq() 中的拼写错误,并重命名了温度变量以便更清晰。
-
src/ai.js:
- 我将handleOutput() 函数移至模块handleOutputFile() 中以允许将来重用。
-
src/getFileContent.js:
- 此处需要进行最小的更改;我只是重命名了文件路径和变量名称,以提高可读性和清晰度。
重构后的 Git Rebase
在重构过程中进行了 11 次提交后,有必要对它们进行整合。为了保持提交历史记录干净,我使用以下命令执行了交互式变基:
git rebase main -i
VSCode,配置为我的 Git 编辑器,提示我压缩提交。压缩后,我进行了一次包含所有相关更改的提交。然后我使用 git commit --amend 更新提交消息,而不是在合并到主分支之前创建新的提交。
Conclusion
This week's experience with git rebase has provided me with valuable insights. Rebase is an essential tool for maintaining a clean, linear commit history, free from unnecessary merges. By mastering git rebase, I am now able to organize commit messages efficiently, minimizing confusion and ensuring a streamlined development workflow.
The refactoring effort has improved the structure and maintainability of the VShell codebase. Applying key design patterns like extracting functions and classes, I have made the codebase more modular, reusable, and easier to work with moving forward.

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.
