How can you implement regions a.k.a. Code collapse for JavaScript in Visual Studio? If there are hundreds of lines in javascript, it'll be more understandable using code folding with regions as in vb/C#. #region My Code #endregion javascript visual-studio folding code-regions.

You can choose to hide some code from view by collapsing a region of code so that it appears under a plus sign (+). You expand a collapsed region by clicking the plus sign. If you are a keyboard user, you can choose Ctrl+M+M to collapse and expand. You can also collapse an outlining region by double-clicking any line in the region on the outlining margin, which appears just to the left of the code. You can see the contents of a collapsed region as a tooltip when you hover over the collapsed region.

Note

This topic applies to Visual Studio on Windows. For Visual Studio for Mac, see Source editor (Visual Studio for Mac).

Regions in the outlining margin are also highlighted when you hover over the margin with the mouse. The default highlighting color may seem rather faint in some color configurations. You can change it in Tools > Options > Environment > Fonts and Colors > Collapsible Region.

When you work in outlined code, you can expand the sections you want to work on, collapse them when you are done, and then move to other sections. When you do not wish to have outlining displayed, you can use the Stop Outlining command to remove the outline information without disturbing your underlying code.

The Undo and Redo commands on the Edit menu affect these actions. The Copy, Cut, Paste, and drag-and-drop operations retain outlining information, but not the state of the collapsible region. For example, when you copy a region that is collapsed, the Paste operation will paste the copied text as an expanded region.

Caution

When you change an outlined region, the outlining may be lost. For example, deletions or Find and Replace operations may erase the end of the region.

The following commands can be found on the Edit > Outlining submenu. Android studio comment shortcut.

Hide Selection(Ctrl+M, Ctrl+H) - Collapses a selected block of code that would not normally be available for outlining, for example an if block. To remove the custom region, use Stop Hiding Current (or Ctrl+M, Ctrl+U). Not available in Visual Basic.
Toggle Outlining Expansion- Reverses the current hidden or expanded state of the innermost outlining section when the cursor lies in a nested collapsed section.
Toggle All Outlining(Ctrl+M, Ctrl+L) - Sets all regions to the same collapsed or expanded state. If some regions are expanded and some collapsed, then the collapsed regions are expanded.
Stop Outlining(Ctrl+M, Ctrl+P) - Removes all outlining information for the entire document.
Stop Hiding Current(Ctrl+M, Ctrl+U) - Removes the outlining information for the currently selected user-defined region. Not available in Visual Basic.
Collapse to Definitions(Ctrl+M, Ctrl+O) - Collapses the members of all types.
Collapse Block:<logical boundary>(Visual C++) Collapses a region in the function containing the insertion point. For example, if the insertion point lies inside a loop, the loop is hidden.
Collapse All in: <logical structures>(Visual C++) Collapses all the structures inside the function.

You can also use the Visual Studio SDK to define the text regions you want to expand or collapse. See Walkthrough: Outlining.

Visual Studio For Mac Code Collapse

The #Region directive enables you to collapse and hide sections of code in Visual Basic files. The #Region directive lets you specify a block of code that you can expand or collapse when using the Visual Studio code editor. The ability to hide code selectively makes your files more manageable and easier to read. For more information, see Outlining.

#Region directives support code block semantics such as #If..#End If. This means they cannot begin in one block and end in another; the start and end must be in the same block. #Region directives are not supported within functions. https://hannin.netlify.app/download-visual-studio-for-mac.html.

  • Place the section of code between the #Region and #End Region statements, as in the following example:

    The #Region block can be used multiple times in a code file; thus, users can define their own blocks of procedures and classes that can, in turn, be collapsed. #Region blocks can also be nested within other #Region blocks.

    Note

    Hiding code does not prevent it from being compiled and does not affect #If..#End If statements.
