    # 1030_git_day3_ruby_day2 [![hackmd-github-sync-badge](https://hackmd.io/NfcopxcNQYqR57gwVrbpOw/badge)](https://hackmd.io/NfcopxcNQYqR57gwVrbpOw) --- #### 上課日期:1029 ###### tags: `git` ###### tags: `ruby` ###### tags: `5xruby` --- # 相關連結: - [【GIT 小教室】](https://www.youtube.com/playlist?list=PLBd8JGCAcUAF2_im__kqZTfEAKnlmfPJy) --- # 0. 綱要 / 目錄 1. GitHub說明 --- # 1. GitHub說明 > 接續上次的部分 1. 功能說明 1. issue - 討論問題用 - 只有close,沒有刪除 - 也有人拿來寫[部落格](https://github.com/aszx87410/blog) - 按星星的意思 - 前端三大框架:VAR, vue, react,angular已經很後面 1. project - 專案管理,類似trello - column = 看板(trello) - note = 卡片(trello) 1. 將專案拉下來 - `$ git clone (專案位置)` - 專案位置可看 **[Code]** 裡的選項:https, ssh, GitHub CLI # 2. Clone、fetch > 說明這部分是什麼 1. 將專案clone會將全部都拉下來,包含分支 - 遠端節點分支origin - 遠端分支和本地分支的差別: - 通常只會clone一次,之後都是pull和push 2. 遠端進度與本地進度 3. fetch 4. 怎樣移動master? - reset - merge - git remote add origin xxxx ``` $ git fetch oirgin master $ git merge oirgin/master ``` - pull = fetch + merge # 3. 分支的重要性 ### 3.1. 分支的重要性 - 舉例: 如果沒有開分支,大家都會主幹做更新,會產生很多枝節,結構會變得很亂。 ### 3.2. fork - 在GitHub上操作 - 發出PullRequest - **說明/註解要寫清楚**,別人才知道這個PR的意思,是否要接收這個PR。 - 發生衝突: - squash and merge:把多顆捏成一顆(不在意過去的歷史) -多人專案使用方法: 1. 有一個人先開一個commit接下來專案的協作者各自fork一份到自己的GitHub裡(同一個專案之後才推得上去) 2. 你做好自己的部分後發通知給主要的專案者 3. 接下來以main作為主要的HEAD,當分支經過大部分人確認過之後再merge進來(如果在公司就是資深工程師或boss審核) 4. 每次做之前要先pull原本的進度在push上去 ### 延伸閱讀: - [Learn Git Branching](https://learngitbranching.js.org/?locale=zh_TW) --- --- # 4. Ruby ### 4.1. Ruby > 基本介紹,自己看先修 - 小括號要注意 - 縮排不要四個空白,兩個就好(一般習慣) - 縮排很多空白太多也會影響版面的使用 ### 4.2. Rack:小型框架 - [Rack專案@GitHub](https://github.com/rack/rack) - Rack是一種介面 - 不用特別安裝,通常安裝ruby時即有一起安裝 - 工具:[LiveShare on VScode](https://xiaosean.github.io/vscode/2018-05-19-VSCode-Live-share/) :::info - 使用rack列印出訊息 - ![](https://i.imgur.com/gRoExtz.png) - 第4行:是給瀏覽器Header看的,跟HTML裡的Header是不同東西 - 第5行:實際出現在瀏覽器的東西是引號內的訊息 ::: - chrome的外掛,可能會影響html原始碼的內容 - [duck typing鴨子型別](https://zh.wikipedia.org/wiki/%E9%B8%AD%E5%AD%90%E7%B1%BB%E5%9E%8B) :::info - [列印特定文字和環境變數] ![](https://i.imgur.com/3qwFDwy.png) - 結果 ![](https://i.imgur.com/3ITHMQm.png) ::: - rails就是一個大型的rack,指令透過伺服器發生作用 --- ### 參考資源 - [Ruby的Gem套件管理服務](https://rubygems.org/) - [HTTP 狀態碼](https://developer.mozilla.org/zh-TW/docs/Web/HTTP/Status) ### 延伸閱讀 - [1104 直播測試 互動式 Rebase](https://www.youtube.com/watch?v=4iyWWyg1dFE)
