Indent function arguments

[voidtrance]

I am not sure whether this should be a bug report or a feature request, so I am not entirely sure what information to include.

I am using:

• VSCode 1.23.1
• C/C++ extension: 0.17.0
• C++ Intellisense 0.2.2
• C/C++ Clang Command Adapter 0.2.2

The issue that I am having is that function arguments, which span multiple lines are not indented properly. What I would expect is this:

function_call(arg1, arg2, arg3,
              arg4, arg5);

What I get is this:

function_call(arg1, arg2, arg3,
arg4, arg5);

If I were to use the Tab key to indent the second argument line, I can't indent to the correct spot without doing it manually (Hit Tab until I get close and then hit Space until aligned).

Related to #883 .

Forgive my lack of GitHub knowledge but what does the "help wanted" label mean here? Do you need help from me in order to fix this issue.

Indentation is one of the main reasons why I can't start using vscode on regular basis and I'd like to get this fixed so if there is anything required from me, I'd like to know about it.

It's just a tag specific to our repo. We use it mean that we believe it can be fixed via changes to our open source code on this repo, so if anyone wants it fixed sooner than we can get around to it then we could accept a pull request. We don't need your help specifically. Fixing this issue might be very difficult or impossible though using the regular expression mechanism present in VS Code (see #883 for another user's attempt to fix auto-indent).

Our team has mostly been focused on implementing the intellisense features and not editing/indentation issues.

I understand that fixing this might be difficult. Therefore, the following is my plea...

In my opinion, this comes down to code-style support. A lot of projects do specify a coding style that all committed code should adhere to. This includes indentation. As such, it would be important for VS Code to be able to support various coding styles.

As an example, I wouldn't be able to use VS Code without the pain of manually formatting indentation on the Linux kernel.

To be perfectly honest, I've tried many, many IDEs and automatic and intelligent indentation has been the major deterrent in almost all of them.

Do you use clang-format? It may not be ideal that we don't auto-indent for you while typing (yet), but you can configure VS Code to run clang-format on your file when you save or when you type a closing curly brace, if either of those are options for you.

[voidtrance]

No, I don't use it. Thank you for the suggestion. At this point, I am reluctant to have VS Code run an external application to get the formatting right. I also don't want to spend the time to configure clang-format. I see the indentation capability as a core feature (yes, I realize that this is personal opinion/preference).

Unfortunately, this means that I have to abandon VS Code for now. It's too bad because I generally like it but the indentation is a must-have for me. Hopefully, this bug will get some attention soon.

This will be addressed by #657
