vscode-基礎操作
本文件將以python開發者的角度進行介紹,主要以界面使用、基本開發流程以及插件使用做介紹。其他如git操作使用、docker遠端連線功能請參閱連結。
vscode概念與特色
1.概念
- 以檔案夾作為專案管理
- 設定值(setting.json)分為user(全域) & workingspace(專案)
2.特色
- 為何要用vscode?–>『因為它免費』
- 輕量化開發程式–>快速啟動,容量小
- 支援多種語言開發功能及套件–>實用面廣
- 簡單的版本管理界面–>整合git
- 開源及快速bug修正–>每月更新
vscode界面介紹
1.Activity Bar
左側黃色框為快速功能鍵,點擊可以展開跟關閉SideBar,分別會呈現explorer、search、source control(GIT)、debug、extension等視圖(可自由增加)
2.Side Bar
中間藍色框為快速功能鍵的顯示列表,會顯示快速功能鍵之相關資訊,呈現不同功能的view視圖,最常用的view是explorer,以樹狀選單呈現,瀏覽選取專案裡的不同資料夾跟檔案
3.Editor+Panels
右側為上方為程式撰寫區域,可自由打開多個Editor並自由決定這些editor要並排還是垂直排列;下方面板主要用於呈現extenison的output、debug的資訊,程式碼的問題以及整合進vscode的termimal
4.Status Bar
下方綠色框所標示的藍色區域為狀態列,,用於呈現開啟且在activity狀態的editor的資訊,如當前光標所在的line、column位置,縮排一次右移幾個column(tab size),編輯檔案的語言…等等

1. Variables:變數值
執行程式時顯示當下變數數值,透過點擊兩下可修改變數,可觀察修改變數後之執行結果
2.Watch:自定義程式表達式(expression)
當變數過多時可字定義自己需要觀察的變數於此欄位,同時可對欄位輸入方程式來查看特定數值,如圖中輸入"a+1",變數a為1時,該欄位會顯示a+1=2
3.Call stack:函數的執行堆疊(stack)
主要監控函數的操作(def),圖中程式執行到第二行,所以會看到最上面是fool() 2:5,表示現在正在fool()函數中,第二行第五個字。
4.Breakpoints:中斷點的位置
勾勾可以開關中斷點,關閉時可保留下該中斷點位置。
對中斷點點擊右鍵,編輯中斷點(edit breakpoint):
1.Expression(運算式):運算式評估為true時中斷(ex:當某變數大於多少時中斷)

依次是 Contiune, Step Over, Step In, Step Out, Restart, Stop
Contiune:繼續執行
Step Over:不離開當前執行函數,單步執行到下一行
Step In:單步執行到下一行。若有函數就進入
Step Out:離開當前函數後,停留在下一行
Restart:整個 deubg 重新執行
Stop:終止整個 deubg 模式
7.Evaluate expression:程式測試
可在此直接輸入程式碼進行"即時"測試

- 快捷鍵:
Command(Ctrl)+Option(Alt)+K# 在此行建立或取消一個 Bookmark
Command(Ctrl)+Option(Alt)+L# 快速移動到下個 Bookmark
Command(Ctrl)+Option(Alt)+J# 快速移動到上個 Bookmark
雲端備份vscode之環境及套件設定(但會覆蓋目前電腦中的所有設定,請謹慎使用)
步驟:
1.建立token
登入github點選settings

選擇左下developer settings

選擇左方Personal access token

新增Generate new token

輸入Note、點選gist(Creat gists),再點選Generate token


2.複製token
於Personal access tokens頁面中複製此token,(產生的 Access Token 之後不可查詢,僅能重新生成,所以務必在此處複製備份,以利後續設定之用)

3.設定Settings Sync
(方式一)
回vscode中下載"Settings Sync"後,快捷鍵"Shift + Alt + U"輸入token

成功的話會自動跑出 syncSummary.txt的文件
(此檔記錄以利後續用此序號於其他地方下載環境用)

(方式二)
也可使用vscode UI界面設定,按 F1 開啟指令面板 Command Palette,輸入 Sync: Update/Upload Settings,開啟擴充套件,並點擊右側 EDIT CONFIGURATION 按鈕,進入上傳下載功能設定頁面
上傳下載功能頁面中,於右上角 Access Token 欄位中輸入先前備份的 GitHub gist access token

同時按下 Shift + Alt + U,此時 Settings Sync 會創建新的 Gist,於右下角上傳設定至 Gist 的彈窗訊息中點選 Yes

上傳過程中會彈出 OUTPUT 視窗提示進度,並於右下角出現訊息通知使用者複製新創建 Gits 的 ID,供其他裝置下載備份的設定檔時使用。在通知訊息視窗上按右鍵點 Copy Text 可複製內容

(方式三)
若上述方式都出現問題,可直接到json檔紀行編輯
於vscode中使用快捷鍵"ctrl + Shift + p",輸入Sync:Advanced Options

編輯本機延伸模組設定

於token處編輯github token並儲存

4.上傳設定紀錄
快捷鍵"Shift + Alt + U",會開始上傳本機端vscode相關設定於github中

5.下載設定紀錄
到任何一台電腦中安裝Settings Sync 插件

接著進入Settings Sync擴充套件設定

將之前建立的Gist ID 貼上

按下下載同步快捷鍵"Shift + Alt + D",就可以將環境及相關套件設定檔案都下載下來摟!
再次重申:會覆蓋目前電腦中的所有設定,請謹慎使用
9.git系列工具(建議可全部安裝,於git運作上有許多幫助)
可看美美的graph、加入tag等功能

可以看到之前的git history, 還可以看到對特定檔案的file hisory

git stash暫存功能

可簡易的比較幾次commit的差異及變換

觀察是誰編輯過此段程式碼
