CSharpier Formatter for Visual Studio Code

This extension makes use of the dotnet tool CSharpier to format your code and is versioned independently.

CSharpier is an opinionated code formatter for c#. It uses Roslyn to parse your code and re-prints it using its own rules. The printing process was ported from prettier but has evolved over time.

Installation

Install through VS Code extensions. Search for CSharpier

Can also be installed in VS Code: Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.

ext install csharpier.csharpier-vscode

CSharpier Version

The extension determines which version of csharpier is needed to format a given file by looking for a dotnet manifest file. If one is not found it looks for a globally installed version of CSharpier.

Dotnet Commands

The extension makes use of dotnet commands and uses the following logic to locate dotnet.

• If dotnet.dotnetPath is set try using that to find dotnet
• If omnisharp.dotNetCliPaths is set try using that to find dotnet
• Try running dotnet --info to see if dotnet is on the PATH
• For non-windows - Try running sh -c "dotnet --info" to see if dotnet is on the PATH

Default Formatter

To ensure that CSharpier is used to format c# files, be sure to set it as the default formatter.

  "[csharp]": {
    "editor.defaultFormatter": "csharpier.csharpier-vscode"
  }

Usage

Keyboard Shortcuts

Visual Studio Code provides default keyboard shortcuts for code formatting. You can learn about these for each platform in the VS Code documentation.

If you don't like the defaults, you can rebind editor.action.formatDocument and editor.action.formatSelection in the keyboard shortcuts menu of vscode.

Format On Save

Respects editor.formatOnSave setting.

Found in the settings at Text Editor | Formatting | Format on Save

You can turn on format-on-save on a per-language basis by scoping the setting:

// Set the default
"editor.formatOnSave": false,
// Enable per-language
"[csharp]": {
    "editor.formatOnSave": true
}

Devcontainers

CSharpier supports DevContainers if it is installed as a local dotnet tool.

# if no .config/dotnet-tools.json file exists
dotnet new tool-manifest

# add csharpier to manifest
dotnet tool install csharpier

# rebuild container image
