Equivalent of #region for C++

Question

What\'s the C++ equivalent of #region for C++ so I can put in custom code collapsible bits and make my code a little easier to read?

Answer 1

The first answer from this question mentions another alternative. It is not applicable in all situations, though.

Method: Use {...} instead which natively supports code collapsing in Visual Studio.

1. Enable option: Tools -> Options -> Text Editor -> C/C++ -> Formatting -> OutLine Statement Blocks -> True.

2. Put your in different scopes {...}, then it will collapse the code in different scopes:

Answer 2

Just an addition to other answers. The region definition varies from IDE to IDE.

For Mac development in Xcode you can use a pragma:

#pragma mark

Answer 3

In addition to #pragma region…#pragma endregion for Visual Studio, many IDEs support the following syntax for regions in any {}-delimited, //-commented language:

//{ Region header text.
…
//}

Notable examples include Code::Blocks and FlashDevelop, and any other editor that uses the Scintilla editing component, such as Notepad++, Geany, Komodo Edit, and many more.

Answer 4

There isn't an equivalent in C++. However IDEs should be able to collapse sections.

It is also possible to use something like this:

#pragma region

#pragma endregion A comment about the region.

But probably not very portable
