Visual Studio IntelliCode

百度 中新社长春3月22日电(郭佳柴家权)22日，由东北五校就业协作体(哈尔滨工业大学、哈尔滨工程大学、吉林大学、东北大学、大连理工大学)共同邀请、联动协作推动的2018届毕业生就业创业大市场在吉林大学开放。

The Visual Studio IntelliCode extension provides AI-assisted development features for Python, TypeScript/JavaScript and Java developers in Visual Studio Code, with insights based on understanding your code context combined with machine learning.

You'll need Visual Studio Code October 2018 Release 1.29.1 or later to use this extension. For each supported language, please refer to the "Getting Started" section below to understand any other pre-requisites you'll need to install and configure to get IntelliCode completions.

Whole-line Autocomplete

In the most recent update, IntelliCode can predict up to a whole line of code based on your current context for Python, JavaScript, and TypeScript.

Predictions appear as grey-text to the right of your cursor. Users can press TAB to accept the prediction or keep typing to steer the prediction together with the IntelliSense list.

The model that powers grey-text runs locally and can be enabled/disabled per language. To disable grey-text functionality for all languages, developers may also uninstall the IntelliCode Completions extension.

API Usage Examples

Ever wish you could easily access code examples for APIs you work with? IntelliCode API Usage Examples makes that a reality. Now with just one click you can access examples for over 100K different APIs!

IntelliCode API Usage Examples is a feature that lets you see real-world examples of how other developers have used a given function. Examples shown are from public open source repositories on GitHub.

This feature currently supports Python, JavaScript and TypeScript (including JSX and TSX files).

Starred IntelliSense members

This extension provides AI-assisted IntelliSense by showing recommended completion items for your code context at the top of the completions list. The example below shows this in action for Python code.

When it comes to overloads, rather than taking the time to cycle through the alphabetical list of member, IntelliCode presents the most relevant one first. In the example shown above, you can see that the predicted APIs that IntelliCode elevates appear in a new section of the list at the top with members prefixed by a star icon. Similarly, a member’s signature or overloads shown in the IntelliSense tool-tip will have additional text marked by a small star icon and wording to explain the recommended status. This visual experience for members in the list and the tool-tip that IntelliCode provides is not intended as final – it is intended to provide you with a visual differentiation for feedback purposes only.

Contextual recommendations are based on practices developed in thousands of high quality, open-source projects on GitHub each with high star ratings. This means you get context-aware code completions, tool-tips, and signature help rather than alphabetical or most-recently-used lists. By predicting the most likely member in the list based on your coding context, AI-assisted IntelliSense stops you having to hunt through the list yourself.

Getting Started

Install the Visual Studio IntelliCode extension by clicking the install link on this page, or install from the Extensions tab in Visual Studio Code. Then follow the language-specific instructions below.

For TypeScript/JavaScript users:

That's it -- just open a TypeScript or JavaScript file, and start editing.

Version 1.2.16 and above of the IntelliCode extension even works for TypeScript/JavaScript on web based instances of VSCode such as github.dev, vscode.dev, and GitHub codespaces.

For Python users:

1. Set up the Python extension by following the steps in the Python tutorial

2. Make sure that you're using Pylance as the Python language server by opening the VSCode settings page (File -> Preferences -> Settings)

3. Start editing Python files

4. After the Python language server finishes initializing, you should now see recommended completions

For Java users:

1. Set up the Java extension for Visual Studio Code by following the steps in the Java Tutorial

2. Make sure that you have a minimum of Java 8 Update 151 installed

3. Reload Visual Studio Code after enabling the Java extension

4. After the Java language server finishes initializing, you should now see recommended completions

For T-SQL users:

1. Set up the mssql extension for Visual Studio Code by following the steps in the T-SQL Tutorial

2. Reload Visual Studio Code after enabling the mssql extension

3. After the mssql language server finishes initializing, you should now see recommended completions
