Getting code suggestions

GitHub Copilot offers coding suggestions as you type. For example, in a Java file, create a class by typing class Test.

GitHub Copilot will automatically suggest a class body in grayed text. 候補を受け入れるには、Tab キーを押します。

You can also describe something you want to do using natural language within a comment, and Copilot will suggest the code to accomplish your goal. For example, type this comment in a Java file:

Java
// find all images without alternate text
// and give them a red border
void process () {

GitHub Copilot will automatically suggest code. 候補を受け入れるには、Tab キーを押します。

GitHub Copilot will attempt to match the context and style of your code. You can always edit the suggested code.

Tip

If you receive limited or no suggestions from Copilot, you may have duplication detection enabled. For more information about duplication detection, see "個人のサブスクライバーとしての Copilot ポリシーの管理."

Showing alternative suggestions

特定の入力に対して、GitHub Copilot が複数の候補を提示することがあります。 使う候補を選択するか、すべての候補を拒否できます。

For example, type the following line in a Java file, and press Enter:

Java
private int calculateDaysBetweenDates(Date date1,

GitHub Copilot will show you a suggestion.

Now hover over the suggestion to show the GitHub Copilot control for choosing suggestions. To display next or previous suggestions, click the forward or back arrow button in the control.

You can also use keyboard shortcuts to show alternative suggestions:

OSSee next suggestionSee previous suggestion
macOSOption+]Option+[
Windows or LinuxAlt+]Alt+[

提案を受け入れるには、Copilot コマンド パレットで [承諾する] をクリックするか、Tab キーを押します。すべての提案を拒否するには、Esc キーを押します。

Showing multiple suggestions in a new tab

GitHub Copilot プランの最初の候補を使用しない場合は、新しいタブに複数の候補を表示できます。

For example, type the following line in a Java file:

Java
private int calculateDaysBetweenDates(Date date1,

GitHub Copilot will show you a suggestion.

To open a new tab with multiple additional suggestions, use the following keyboard shortcut, then click Open GitHub Copilot:

OSOpen multiple suggestions
macOSCommand+Shift+A
Windows or LinuxCtrl+Enter

To accept a suggestion, below the suggestion, click Accept suggestion NUMBER. To reject all suggestions, close the tab.

Accepting partial suggestions

If you don't want to accept an entire suggestion from GitHub Copilot, you can accept the next word or the next line of a suggestion.

For example, type the following line in a Java file:

Java
private int calculateDaysBetweenDates(Date date1,

GitHub Copilot will show a suggestion in grayed text. The exact suggestion may vary.

Now hover over the suggestion to show the GitHub Copilot control for choosing suggestions. To accept only the next word of the suggestion, click Accept Word in the control.

Alternatively, you can use a keyboard shortcut to accept the next word of a suggestion:

OSAccept Next WordAccept Next Line
macOSCommand+Command+Control+
Windows or LinuxControl+Control+Alt+

If you want to accept the next line of a suggestion, you will need to set a custom keyboard shortcut for the command editor.action.inlineSuggest.acceptNextLine. For more information on setting custom keyboard shortcuts, see "環境での GitHub Copilot の構成."

Getting code suggestions

GitHub Copilot can provide you with inline suggestions as you create SQL databases in Azure Data Studio. For example, if you're writing a query that joins two tables, Copilot may suggest the join condition from columns in the open editor, other files in the workspace, and common syntax patterns.

In a SQL file, type the following query:

SQL
SELECT [UserId], [Red], [Orange], [Yellow], [Green], [Blue], [Purple], [Rainbow]
FROM [Tag].[Scoreboard]

GitHub Copilot will automatically suggest a join condition in grayed text. The exact suggestion may vary. 候補を受け入れるには、Tab キーを押します。

You can also describe something you want to do using natural language within a comment, and Copilot will suggest the code to accomplish your goal. For example, type this comment in a SQL file:

SQL
SELECT TokenColor, COUNT(UserID) AS UserCount
FROM Tag.Users
GROUP BY TokenColor
-- pivot that query on tokencolor for Purple, Blue, Green, Yellow, Orange, Red
-- and rename the columns to match the colors
SELECT [Purple], [Blue], [Green], [Yellow], [Orange], [Red]

GitHub Copilot will automatically suggest code. 候補を受け入れるには、Tab キーを押します。

Tip

If you receive limited or no suggestions from Copilot, you may have duplication detection enabled. For more information on duplication detection, see "個人のサブスクライバーとしての Copilot ポリシーの管理."
