The Mac's snipping or capture tool doesn't work everywhere. For instance, you won't be able to make snippets on Mac of certain apps (Apple TV and Netflix, for example) due to Digital Rights Management (DRM) restrictions.
Snippet For Mac
Code snippets, often referred to as code templates, are useful for efficient programming as they allow the insertion and editing of pre-written blocks of code. Using code snippets can be convenient for quickly adding common patterns, or even for learning new patterns when as the developer you are unsure of syntax. There are templates provided for C#, F#, HTML, XML, Python, and Razor.
After a code snippet is inserted into the editor, any keywords defined are highlighted and can be edited by tabbing between them. Keywords behave like a "variable" in the code snippet and are defined by placing a dollar-sign $ before and after the name of the keyword.
The easiest way and least-expensive way to create snippets is to open System Preferences, click on the Keyboard icon, and then click on the Text tab. Now, to create a snippet, click the little + button at the bottom to add a new snippet.
A code snippet is block of templated text that includes named arguments that are substituted when inserted by a developer. If we created a code snippet for our view model property, it'd look something like this:
In Visual Studio Mac we manage our code snippets in the Code Snippets panel in Visual Studio Macs Preferences window. Here we can add, delete and edit code snippets for any language that Visual Studio Mac supports.
If you're already using Alfred's Clipboard History and you've just copied something to your clipboard which you'd like to save for use later, pop up your Clipboard History Viewer and use the Cmd + S hotkey to save the selected entry to your snippets.
You can also create rich text snippets. We recommend using plain text snippets in any case where you want the pasted text to match the destination format, and rich text when you want to force the formatting (e.g. setting the colours, fonts and links)
Snippet auto-expansion is disabled by default. To activate it, launch Alfred's preferences to Features > Snippets and check the box for "Automatically expand snippets by keyword". Follow the instructions, or take a look at the step-by-step guide to setting up auto-expansion for details.
Once you've activated, make sure you've set a keyword for your snippet, and checked the box to allow auto-expansion. To use the snippet, simply type the keyword you set into the app or text field you want. As if by magic, your keyword will be replaced will the full text snippet!
To pop up the Snippets Viewer, you can either set a hotkey for it in the Snippets preferences window, or you can pop up your Clipboard History Viewer with its hotkey and choose "All Snippets" at the top. You'll then be shown all your collections and individual snippets, which you can filter by typing part of the title or keyword for the snippet.
If you find yourself running the same code in the Console repeatedly, consider saving the code as a snippet instead. Snippets are scripts that you author in the Sources panel. They have access to the page's JavaScript context, and you can run them on any page. Snippets are an alternative to bookmarklets.
You can see the available snippets for a language by running the Insert Snippet command in the Command Palette to get a list of the snippets for the language of the current file. However, keep in mind that this list also includes user snippets that you have defined, and any snippets provided by extensions you have installed.
You can easily define your own snippets without any extension. To create or edit your own snippets, select Configure User Snippets under File > Preferences (Code > Preferences on macOS), and then select the language (by language identifier) for which the snippets should appear, or the New Global Snippets file option if they should appear for all languages. VS Code manages the creation and refreshing of the underlying snippets file(s) for you.
Snippets files are written in JSON, support C-style comments, and can define an unlimited number of snippets. Snippets support most TextMate syntax for dynamic behavior, intelligently format whitespace based on the insertion context, and allow easy multiline editing.
Additionally, the body of the example above has three placeholders (listed in order of traversal): $1:array, $2:element, and $0. You can quickly jump to the next placeholder with Tab, at which point you may edit the placeholder or jump to the next one. The string after the colon : (if any) is the default text, for example element in $2:element. Placeholder traversal order is ascending by number, starting from one; zero is an optional special case that always comes last, and exits snippet mode with the cursor at the specified position.
You can add the isFileTemplate attribute to your snippet's definition if the snippet is intended to populate or replace a file's contents. File template snippets are displayed in a dropdown when you run the Snippets: Populate File from Snippet command in a new or existing file.
Single-language user-defined snippets are defined in a specific language's snippet file (for example javascript.json), which you can access by language identifier through Preferences: Configure User Snippets. A snippet is only accessible when editing the language for which it is defined.
Multi-language and global user-defined snippets are all defined in "global" snippet files (JSON with the file suffix .code-snippets), which is also accessible through Preferences: Configure User Snippets. In a global snippets file, a snippet definition may have an additional scope property that takes one or more language identifiers, which makes the snippet available only for those specified languages. If no scope property is given, then the global snippet is available in all languages.
You can also have a global snippets file (JSON with file suffix .code-snippets) scoped to your project. Project-folder snippets are created with the New Snippets file for ''... option in the Preferences: Configure User Snippets dropdown menu and are located at the root of the project in a .vscode folder. Project snippet files are useful for sharing snippets with all users working in that project. Project-folder snippets are similar to global snippets and can be scoped to specific languages through the scope property.
With tabstops, you can make the editor cursor move inside a snippet. Use $1, $2 to specify cursor locations. The number is the order in which tabstops will be visited, whereas $0 denotes the final cursor position. Multiple occurrences of the same tabstop are linked and updated in sync.
Placeholders can have choices as values. The syntax is a comma-separated enumeration of values, enclosed with the pipe-character, for example $. When the snippet is inserted and the placeholder selected, choices will prompt the user to pick one of the values.
The examples are shown within double quotes, as they would appear inside a snippet body, to illustrate the need to double escape certain characters. Sample transformations and the resulting output for the filename example-123.456-TEST.js.
You can create custom keybindings to insert specific snippets. Open keybindings.json (Preferences: Open Keyboard Shortcuts File), which defines all your keybindings, and add a keybinding passing "snippet" as an extra argument:
The keybinding will invoke the Insert Snippet command but instead of prompting you to select a snippet, it will insert the provided snippet. You define the custom keybinding as usual with a keyboard shortcut, command ID, and optional when clause context for when the keyboard shortcut is enabled.
Also, instead of using the snippet argument value to define your snippet inline, you can reference an existing snippet by using the langId and name arguments. The langId argument selects the language for which the snippet denoted by name is inserted, e.g the sample below selects the myFavSnippet that's available for csharp-files.
Yes, you can hide specific snippets from showing in IntelliSense (completion list) by selecting the Hide from IntelliSense button to the right of snippet items in the Insert Snippet command dropdown.
Key to becoming a TextExpander champion is having a healthy arsenal of quick-to-use snippets for all the things you repeatedly type or share with other people. We may not award trophies for such an achievement (yet?). But we can give you tips on how to turn your tedious typing workflows into TextExpander snippets you can trigger with just a couple keystrokes.
In practice, this means you can use standard OS shortcuts to select and copy a few lines of text, then use (for example) Command + Control + T to turn it into a fresh new TextExpander snippet. Like this:
As I'm using slack in french the code snippet functionality just couldn't be found using the keywords "code", "snippet" or "create". Instead I should have looked for the command "Créer un extrait de texte". The word "code" in that last command name would have been helpful.
Screen captures and snippets are similar to screenshots in the fact that they take a photo of the active windows/desktop. However, they are also different because they allow you to specify a certain region or portion of the screen. Screen captures and snippets are basically the Mac OS X equivalent of the Sniping Tool, for Windows users.
Press the key combo and drag to select the portion of the screen to capture. Alternatively, if you use COMMAND + CONTROL + SHIFT + 4 at the same time, Mac OS X will copy the snippet to the clipboard rather than save it as an image to the desktop. 2ff7e9595c
