#region folding for VS Code installs statistics

Visual Studio Code Custom Folding Extension

This extension enhances the default code folding abilities of Visual Studio Code editor. Regions of code that you'd like to be folded can be wrapped with #region comments.

The precise format of the comment depends on the language. For instance, for C-Style languages, regions are of the form:

/* #region Main / public static void Main(string args[]) { //Your code goes here } / #endregion */

For HTML style languages, you could define a foldable region with the following tags:

Commands

The extension also installs a command to wrap a region comment around the current selection.

• regionfolder.wrapWithRegion (Ctrl+M Ctrl+R)

Configuration

The extension provides configuration settings, allowing you to provide custom region tags for your language.

To provide a custom folding for your language create a settings in your vscode settings file (either user or workspace) that conforms to the following specification.

"maptz.regionfolder": { "[ahk]": { //Language selector "foldEnd": "; #endregion", //Text inserted at the end of the fold "foldEndRegex": ";[\s]#endregion", //Regex used to find fold end text. "foldStart": "; #region [NAME]", //Text inserted at the start of the fold. //Use the [NAME] placeholder to indicate //where the cursor should be placed after //insertion "foldStartRegex": ";[\s]#region[\s](.)", ////Regex used to find fold start text. "disableFolding": false //Turn off #region folding for this language } }

Installing

You can install the latest version of the extension is available on the Visual Studio Marketplace here.

Alternatively, open Visual Studio code, press Ctrl+P and type:

ext install regionfolder

Features

Feature - Default Folding

A new feature is the notion of default folds. Default folds define regions which will be collapsed whenever the file is opened. In the current preview version, default folds are only collapsed when the regionfolder.collapseDefault command is issued from the command palette.

You can create a default fold by creating a Regex expression which defines the default fold for the language of your choice in your settings file. The Regex is defined in the defaultFoldStartRegex property.

In the following example, defined for the Markdown language, default folds are defined as regions in the following form:

The settings for this default fold are below. You can either put this in your Workspace settings file (.vscode/settings.json) or in your user profile settings file:

You can now use the collapseDefaultRegionsOnOpen setting to determine whether regions are collapsed by default when a new file is opened.

Feature - Per-Language Disabling

You can now turn off custom folding on a per-language basis. To do this, you need to add disableFolding to the settings for the particular language. You will need to restart VS Code for the changes to take effect.

So, for instance, to turn off folding for cpp add the following to your settings file:

Feature - Multiple Fold Definitions Per Language (Preview)

The extension now has preview support for defining multiple fold definitions per language. Secondary folds can be defined in the foldDefinitions property in the settings for each language. By settting the isFoldedByDefault value to true, you can ensure that the folds are collapsed by default when the file opens.

The example below is used to collapse Copyright style headers by default in Javascript files:

The .vscode/settings.json file used to define this behaviour is:
