自訂程式碼總覽
透過集合功能整理內容 你可以依據偏好儲存及分類內容。
程式碼自訂功能是 Gemini Code Assist Enterprise 的一項功能，可讓您從 Gemini Code Assist Enterprise 取得基於貴機構私人存放區的程式碼建議，並與貴機構的程式設計樣式保持一致。
程式碼自訂功能可讓 Gemini Code Assist Enterprise 存取私人存放區中的程式碼，方法是分析程式碼並儲存在私人索引中，如下圖所示：
在您編寫程式碼時，Gemini Code Assist 會在您的私人索引中搜尋與您嘗試編寫的程式碼相似的程式碼。接著，系統會在程式碼提示中加入相關的配對結果，並將這些配對結果傳送至 Gemini Code Assist 推薦服務。程式碼自訂功能會每 24 小時重新建立程式碼集索引，確保程式碼建議保持最新狀態，Gemini Code Assist 會將產生的程式碼傳回給您。
與完整程式碼感知功能不同，後者僅限於搜尋 IDE 中目前資料夾和開啟分頁的檔案，而程式碼自訂功能會搜尋索引中的所有存放區。設定程式碼自訂功能後，這項功能會成為程式碼補全和程式碼產生功能的一部分。
Gemini Code Assist 和程式碼自訂功能都是受管理的服務。您可以按月席次授權使用量。
保護私人程式碼的存取權和儲存空間
Google 會透過多種方式保護您儲存的私人程式碼：
- 我們會在專屬的單租戶環境中為您的程式碼建立索引並儲存。
- 行政存取權控管措施可防止 Google 員工在未經許可的情況下存取您的內容，並視需要取得明確核准。
- Gemini 模型不會使用您的私人原始碼進行訓練。
- 您的結果為私人資料，我們不會將您的結果提供給其他客戶。
如要進一步瞭解 Google 的安全措施，請參閱 Google 安全性總覽。
您可以透過下列方式控管資料存取權：
- 您可以使用身分與存取權管理權限，控管哪些使用者可以從您的程式碼集取得程式碼建議。
- 您可以建立
.aiexclude 檔案，選擇 Gemini Code Assist 索引的特定存放區或存放區部分。
如要在 IDE 中設定程式碼自訂功能，請參閱「設定 Gemini Code Assist 程式碼自訂功能」。

It then includes relevant\nmatches in the code prompt and sends these matches to the\nGemini Code Assist recommendations service. Code customization\nkeeps recommendations fresh by reindexing your codebase every 24 hours to\nensure that code suggestions remain up to date.\nGemini Code Assist returns the generated code to you.\n\nUnlike the full codebase awareness feature, which is limited to searching files\nin the current folder and open tabs in your IDE, code customization searches all\nrepositories in your index. After code customization is set up, it works as part\nof the code completion and code generation features.\n\nBoth Gemini Code Assist and code customization are managed\nservices. You license usage by seats per month.\n\nSecuring access and storage of private code\n\nGoogle provides security of your stored private code in several ways:\n\n- We index and store your code in a dedicated single-tenant environment.\n- [Administrative access controls](https://cloud.google.com/assured-workloads/cloud-provider-access-management/docs/administrative-access) help prevent Google employees from accessing your content without justification and, optionally, explicit approval.\n- The Gemini model doesn't train on your private source code.\n- Your results are private to you, and we don't share your results with other customers.\n\nFor further details on Google's security measures, see the\n[Google security overview](https://cloud.google.com/security/overview/whitepaper).\n\nHere's how you can control access to your data:\n\n- You can use Identity and Access Management permissions to help control individuals who can get code suggestions from your codebase.\n- You can [create an `.aiexclude` file](/gemini-code-assist/docs/code-customization#optional_choose_which_files_are_not_indexed) to choose specific repositories or parts of repositories that Gemini Code Assist indexes.\n\nTo configure code customization in your IDE, see\n\n[Configure Gemini Code Assist code customization](/gemini-code-assist/docs/code-customization).\n\n\nLimitations\n\n- Google limits the number of code repository indexes to one for each project and for each organization.\n- The maximum number of repositories that can be indexed is 20,000.\n- The maximum number of repository groups per code repository index is 500.\n- The maximum number of repositories per repository group is 500.\n- Code customization is supported in the VS Code Gemini Code Assist extension (version 2.18.0+), the IntelliJ Gemini Code Assist plugin (version 1.1.0), Cloud Workstations, and the Cloud Shell Editor.\n- Code customization supports repositories hosted on github.com, gitlab.com, bitbucket.org, and on-premises repositories hosted on GitLab Enterprise, GitHub Enterprise, and Bitbucket Data Center.\n- Code customization doesn't support [GitHub Enterprise Cloud IP restrictions](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization).\n- Code customization supports only Developer Connect connections in the following locations (regions):\n - `us-central1`\n - `europe-west1`\n - `asia-southeast1`\n- Code customization doesn't index documentation, media, or other non-code\n files. Additionally, code customization supports only the following\n languages:\n\n - C, C++, and C#\n - Golang\n - Java\n - JavaScript\n - Kotlin\n - PHP\n - Python\n - Rust\n - TypeScript\n\n All other coding languages are not indexed or used in code customization.
