Apr 18, 2018 April 2018 edited April 2018 in Visual Studio.Net guys should be alway space, this answer from VS for Mac. After you unclick 'Convert tabs to space' in VS Preferences, you still cannot put any tab in your code, even you press the Tab on your keyboard. Jul 24, 2010 Indentation in Visual Studio is controlled with the use of the tab key, which can be used to insert tab characters or spaces into the code or to indent or unindent selected lines. The type of indentation used for a language can have varied effects.
- How do I customize the tab-to-space conversion factor when using Visual Studio Code?For instance, right now in HTML it appears to produce two spaces per press of TAB, but in TypeScript it produce.
- Dec 27, 2015 I'll open this project in Visual Studio 2017 which supports the EditorConfig file natively. Notice the warning at the bottom where VS lets me know that this project has conventions that are different than my own. VS Format Document commands will use tabs rather than spaces for this project. Here is the same doc reformatted in VS.
IntelliSense is a general term for various code editing features including: code completion, parameter info, quick info, and member lists. IntelliSense features are sometimes called by other names such as 'code completion', 'content assist', and 'code hinting.'
IntelliSense for your programming language
Visual Studio Code IntelliSense is provided for JavaScript, TypeScript, JSON, HTML, CSS, SCSS, and Less out of the box. VS Code supports word based completions for any programming language but can also be configured to have richer IntelliSense by installing a language extension.
Below are the most popular language extensions in the Marketplace. Select an extension tile below to read the description and reviews to decide which extension is best for you.
IntelliSense features
VS Code IntelliSense features are powered by a language service. A language service provides intelligent code completions based on language semantics and an analysis of your source code. If a language service knows possible completions, the IntelliSense suggestions will pop up as you type. If you continue typing characters, the list of members (variables, methods, etc.) is filtered to only include members containing your typed characters. Pressing Tab or Enter will insert the selected member.
Options, Text Editor, All Languages
You can trigger IntelliSense in any editor window by typing ⌃Space (Windows, Linux Ctrl+Space) or by typing a trigger character (such as the dot character (.) in JavaScript).
Tip: The suggestions widget supports CamelCase filtering, meaning you can type the letters which are upper cased in a method name to limit the suggestions. For example, 'cra' will quickly bring up 'createApplication'.
If you prefer, you can turn off IntelliSense while you type. See Customizing IntelliSense below to learn how to disable or customize VS Code's IntelliSense features.
As provided by the language service, you can see quick info for each method by either pressing ⌃Space (Windows, Linux Ctrl+Space) or clicking the info icon. The accompanying documentation for the method will now expand to the side. The expanded documentation will stay so and will update as you navigate the list. You can close this by pressing ⌃Space (Windows, Linux Ctrl+Space) again or by clicking on the close icon.
After choosing a method you are provided with parameter info.
When applicable, a language service will surface the underlying types in the quick info and method signatures. In the image above, you can see several any types. Because JavaScript is dynamic and doesn't need or enforce types, any suggests that the variable can be of any type.
Types of completions
The JavaScript code below illustrates IntelliSense completions. IntelliSense gives both inferred proposals and the global identifiers of the project. The inferred symbols are presented first, followed by the global identifiers (shown by the Word icon).
VS Code IntelliSense offers different types of completions, including language server suggestions, snippets, and simple word based textual completions.
| Methods and Functions | method, function, constructor |
| Variables | variable |
| Fields | field |
| Type parameters | typeParameter |
| Constants | constant |
| Classes | class |
| Interfaces | interface |
| Structures | struct |
| Events | event |
| Operators | operator |
| Modules | module |
| Properties and Attributes | property |
| Values and Enumerations | value, enum |
| References | reference |
| Keywords | keyword |
| Files | file |
| Folders | folder |
| Colors | color |
| Unit | unit |
| Snippet prefixes | snippet |
| Words | text |
Customizing IntelliSense
You can customize your IntelliSense experience in settings and key bindings.
Settings
The settings shown below are the default settings. You can change these settings in your settings.json file as described in User and Workspace Settings.
Tab Completion
The editor supports 'tab completion' which inserts the best matching completion when pressing Tab. This works regardless of the suggest widget showing or not. Also, pressing Tab after inserting a suggestions will insert the next best suggestion.
By default, tab completion is disabled. Use the editor.tabCompletion setting to enable it. These values exist:
off- (default) Tab completion is disabled.on- Tab completion is enabled for all suggestions and repeated invocations insert the next best suggestion.onlySnippets- Tab completion only inserts static snippets which prefix match the current line prefix.
Locality Bonus
See Full List On Docs.microsoft.com
Sorting of suggestions depends on extension information and on how well they match the current word you are typing. In addition, you can ask the editor to boost suggestions that appear closer to the cursor position, using the editor.suggest.localityBonus setting.
In above images you can see that count, context, and colocated are sorted based on the scopes in which they appear (loop, function, file).
Suggestion selection
By default, VS Code pre-selects the previously used suggestion in the suggestion list. This is very useful as you can quickly insert the same completion multiple times. If you'd like different behavior, for example, always select the top item in the suggestion list, you can use the editor.suggestSelection setting.
The available editor.suggestSelection values are:
first- Always select the top list item.recentlyUsed- (default) The previously used item is selected unless a prefix (type to select) selects a different item.recentlyUsedByPrefix- Select items based on previous prefixes that have completed those suggestions.
'Type to select' means that the current prefix (roughly the text left of the cursor) is used to filter and sort suggestions. When this happens and when its result differs from the result of recentlyUsed it will be given precedence.
When using the last option, recentlyUsedByPrefix, VS Code remembers which item was selected for a specific prefix (partial text). For example, if you typed co and then selected console, the next time you typed co, the suggestion console would be pre-selected. This lets you quickly map various prefixes to different suggestions, for example co -> console and con -> const.
Snippets in suggestions
By default, VS Code shows snippets and completion proposals in one widget. You can control the behavior with the editor.snippetSuggestions setting. To remove snippets from the suggestions widget, set the value to 'none'. If you'd like to see snippets, you can specify the order relative to suggestions; at the top ('top'), at the bottom ('bottom'), or inline ordered alphabetically ('inline'). The default is 'inline'.
Key bindings
The key bindings shown below are the default key bindings. You can change these in your keybindings.json file as described in Key Bindings.
Note: There are many more key bindings relating to IntelliSense. Open the Default Keyboard Shortcuts (File > Preferences > Keyboard Shortcuts) and search for 'suggest'.
Troubleshooting
If you find IntelliSense has stopped working, the language service may not be running. Try restarting VS Code and this should solve the issue. If you are still missing IntelliSense features after installing a language extension, open an issue in the repository of the language extension.
Tip: For configuring and troubleshooting JavaScript IntelliSense, see the JavaScript documentation.
A particular language extension may not support all the VS Code IntelliSense features. Review the extension's README to find out what is supported. If you think there are issues with a language extension, you can usually find the issue repository for an extension through the VS Code Marketplace. Navigate to the extension's Details page and select the Support link.

Common questions
Why am I not getting any suggestions?
This can be caused by a variety of reasons. First, try restarting VS Code. If the problem persists, consult the language extension's documentation. For JavaScript specific troubleshooting, please see the JavaScript language topic.

This issue is caused by missing type declaration (typings) files in JavaScript. You can check if a type declaration file package is available for a specific library by using the TypeSearch site. There is more information about this issue in the JavaScript language topic. For other languages, please consult the extension's documentation.
