Surround
A simple yet powerful extension to add wrapper snippets around your code blocks.
Features
- Supports language identifiers 🚀New!
- Supports multi selections
- Fully customizable
- Custom wrapper snippets
- You can assign shortcuts for each wrapper snippets separately
- Nicely formatted (Preserves indentations 🚀New!)
- Sorts recently used snippets on top 🚀New!
Demo 2: Wrapping multi selections
How To Use
After selecting the code block, you can
- right click on selected code
- OR press (ctrl+shift+T) or (cmd+shift+T)
to get list of commands and pick one of them.
Hint
Each wrapper has a separate command so you can define keybindings for your favorite wrappers by searching surround.with.commandName in the 'Keyboard Shortcuts' section.

Options
showOnlyUserDefinedSnippets (boolean): Disables default snippets that comes with the extension and shows only used defined snippets.showRecentlyUsedFirst (boolean): Recently used snippets will be displayed on top.showUpdateNotifications (boolean): Shows notification when there is a new version of the extension.
Configuration
Each wrapper snippet config object is defined as ISurroundItem like below:
interface ISurroundItem {
label: string; // must be unique
description?: string;
detail?: string;
snippet: string; // must be valid SnippetString
disabled?: boolean; // default: false
languageIds?: string[];
}
Editing/Disabling existing wrapper functions
Go to "Settings" and search for "surround.with.commandName".
Example surround.with.if:
{
"label": "if",
"description": "if ($condition) { ... }",
"disabled": false,
"snippet": "if(${1:condition}) {\n\t$TM_SELECTED_TEXT\n}$0"
}
Adding new custom wrapper functions
Go to "Settings" and search for surround.custom and edit it like below.
{
"surround.custom": {
// command name must be unique
"yourCommandName": {
// label must be unique
"label": "Your Snippet Label",
"description": "Your Snippet Description",
"snippet": "burrito { $TM_SELECTED_TEXT }$0", // <-- snippet goes here.
"languageIds": ["html", "javascript", "typescript", "markdown"]
},
// You can add more ...
}
}
Defining language-specific snippets
With version 1.1.0, you can define snippets based on the document type by using languageIds option.
Visit VSCode docs the full list of language identifiers.
1. Enabling a snippet for ALL languages
If you want to allow a snippet to work for all document types, simply REMOVE languageIds option.
OR set it to ["*"] as below:
{
"label": "if",
"description": "if ($condition) { ... }",
"disabled": false,
"snippet": "if(${1:condition}) {\n\t$TM_SELECTED_TEXT\n}$0",
"languageIds": ["*"] // Wildcard allows snippet to work with all languages
}
2. Enabling a snippet for ONLY specified languages
If you want to allow a snippet to work with html, typescript and typescriptreact documents, you can use the example below.
{
"label": "if",
"description": "if ($condition) { ... }",
"disabled": false,
"snippet": "if(${1:condition}) {\n\t$TM_SELECTED_TEXT\n}$0",
"languageIds": ["html", "typescript", "typescriptreact"]
}
3. Disabling a snippet for ONLY specified languages
If you want to allow a snippet to work with all document types EXCEPT html, typescript and typescriptreact documents,
you can add - (MINUS) sign as a prefix to the language identifiers (without a whitespace).
{
"label": "if",
"description": "if ($condition) { ... }",
"disabled": false,
"snippet": "if(${1:condition}) {\n\t$TM_SELECTED_TEXT\n}$0",
"languageIds": ["*", "-html", "-typescript", "-typescriptreact"]
}
IMPORTANT NOTES:
- All command names and labels must be unique. If you do not provide a unique command name or label, your custom wrapper functions will override existing ones.
- You can redefine all snippets as long as you provide a valid
SnippetString. Read More
Contribution
As always, I'm open to any contribution and would like to hear your feedback.
Just an important reminder:
If you are planning to contribute to any open source project,
before starting development, please always open an issue and make a proposal first.
This will save you from working on features that are eventually going to be rejected for some reason.
