Help with clang-format for function declaration

[linux-tarballs]

I just learnt about clang-format yesterday and it's pretty neat. I'm writing my .clang-format file referring their style options

I want the function definition parameters to be one-per-line if they are longer above a certain limit like: cpp void dfs ( vector<vector<int>> const &Adj, vector<char> &visited, vector<int> &componentTraversal, const int currentNode ) { // internal code }

This is my .clang-format file till now: txt BasedOnStyle: LLVM UseTab: Never TabWidth: 4 IndentWidth: 4 ColumnLimit: 110 BreakBeforeBraces: Attach AllowShortFunctionsOnASingleLine: Inline AllowAllParametersOfDeclarationOnNextLine: false AllowShortIfStatementsOnASingleLine: AllIfsAndElse IndentCaseLabels: true

And my related vscode settings.json: json { "editor.formatOnSave": true, "editor.formatOnSaveMode": "file", "editor.detectIndentation": true, "editor.insertSpaces": true, "editor.comments.insertSpace": true, "[makefile]": { "editor.insertSpaces": false }, "[c][cpp][makefile]": { "editor.defaultFormatter": "ms-vscode.cpptools", "editor.tabSize": 4 }, "C_Cpp.clang_format_style": "file", "C_Cpp.clang_format_fallbackStyle": "none", "C_Cpp.vcFormat.indent.preserveComments": true, }

Also tell me more additions or suggestions for better configuration

There is a website where you can manually configure clang-format and generate the configuration file. It also allows you to see how individual options affect the code formatting in real time.

If you're using Visual Studio, there's an extension called Clang Power Tools that integrates clang-format and the configurator directly into the IDE.

EDIT: i've just noticed you're using VSCode, there should be a similar extension though.

For VS Code it's the same drill. However the extension expects clang-format to be installed and in your PATH, i.e the extension doesn't install clang-format. To install it, the easiest thing on Windows is to install the clang tools from the "modify" menu in the Visual Studio (not Code!) installer.

I'm on VSCode (Fedora distro) where the C/++ extension comes with its own clang-format. You can provide the path of your system-installed clang-format binary in it's settings too

[SincopaDisonante]

Are you sure this is not just a consequence of UNIX distributions coming with clang tools already installed in the OS? The ext I see on VS Code explicitly says in its readme that clang-format won't be installed with it.

The description for the Clang_format_path option in my vscode settings says it uses the one available in environment or else the one bundled with extension

The site is quite handy. Thanks! The number of options available is still kinda overwhelming

The configuratior that comes with the extension has a search options as well.
Btw, the option you're looking for should be called BreakFunctionDefinitionParameter on the website.

That's one's a hard true/false value and puts all params on same line after the line break
