CSharply

An opinionated tool that organizes C# files according to best practices. Available as a CLI tool, web API, and VS Code extension.

Features

• 🎯 Automatic Code Organization: Organizes all members and using statements
• 🔧 Multiple Interfaces: CLI, Web API, and VS Code extension
• ⚡ Fast Performance: Built with Roslyn for accurate C# parsing
• 🌐 Cross-Platform: Works on Windows, macOS, and Linux
• 📁 Batch Processing: Organize entire directories or single files
• 🔄 Real-time Processing: Web server for fast operations without startup costs per request

Installation

CLI Tool (Global)

dotnet tool install --global CSharply

VS Code Extension

Install from the Visual Studio Marketplace or search for "CSharply" in VS Code extensions.

Usage

Command Line Interface

Organize a single file

csharply organize MyClass.cs

Organize an entire directory

csharply organize ./src

Get help

csharply --help csharply organize --help

Web Server Mode

Start a web server to organize code via HTTP API:

csharply serve csharply serve --port 8149

API Endpoints

• GET /health - Health check
• POST /organize - Organize C# code (plain text body)

Example API Usage

# Organize code via plain text curl -X POST http://localhost:8149/organize \ -H "Content-Type: text/plain" \ -d "using System.Linq; using System; class Test { }"

VS Code Extension

Ctrl+Shift+P, then CSharply: Organize C# file or CSharply: Organize all C# files in workspace folders

What Gets Organized

CSharply organizes your C# code according to Microsoft's coding conventions:

Using Statements

• Sorts alphabetically
• Groups System namespaces first

Rules

Member Order:

1. Namespaces
2. Interfaces
3. Fields
4. Properties
5. Constructors
6. Methods
7. Nested types
8. Enums

Access Modifier Order:

1. public
2. internal
3. protected
4. private

Note: If the file contains pre-processor directives such as #if or #region, the file will not be organized.

Example

Before:

using System.Collections.Generic; using System.Linq; using System; namespace MyProject { public class Example { public void DoSomething1() { } private string _field1; public void DoSomething2() { } public Example() { } public string Property { get; set; } private string _field2; } }

After:

using System; using System.Collections.Generic; using System.Linq; namespace MyProject { public class Example { private string _field1; private string _field2; public Example() { } public string Property { get; set; } public void DoSomething1() { } public void DoSomething2() { } } }

Ignoring Files

CSharply supports a .csharplyignore file to exclude specific files and directories from organization. This is useful for:

• Generated code files
• Third-party libraries
• Legacy code that shouldn't be modified
• Files with custom formatting requirements

Creating a .csharplyignore File

Create a .csharplyignore file in your project root or any directory you want to organize. The file uses gitignore-style patterns:

# Ignore all generated files **/Generated/ **/*.Designer.cs **/*.g.cs # Ignore specific files Models/LegacyModel.cs Controllers/ThirdPartyController.cs # Ignore by pattern **/*Template*.cs **/Migrations/**/*.cs # Ignore entire directories bin/ obj/ packages/

Pattern Syntax

The .csharplyignore file supports the same globbing patterns as .gitignore:

Pattern	Description	Example
*.cs	Match any .cs file	Generated.cs, Model.cs
**/Generated/	Match Generated directory anywhere	src/Generated/, test/Generated/
Models/*.cs	Match .cs files in Models directory	Models/User.cs
**/*.Designer.cs	Match Designer.cs files anywhere	Form1.Designer.cs
!Important.cs	Negation - don't ignore this file	Override previous ignore rules

How It Works

1. CSharply looks for .csharplyignore files starting from the target directory
2. It walks up the directory tree to find additional ignore files
3. Patterns are applied in order, with more specific files taking precedence
4. Files matching any pattern are skipped during organization

Examples

Basic Project Structure

MyProject/ ├── .csharplyignore # Root ignore file ├── src/ │ ├── .csharplyignore # Source-specific ignores │ ├── Controllers/ │ ├── Models/ │ └── Generated/ # Ignored directory ├── tests/ └── bin/ # Ignored directory

Sample .csharplyignore for ASP.NET Core

# Build outputs bin/ obj/ publish/ # Generated files **/*.Designer.cs **/*.g.cs **/Migrations/*.cs # Third-party code **/ThirdParty/ **/External/

Sample .csharplyignore for WinForms/WPF

# Designer files **/*.Designer.cs **/*.g.cs # Build outputs bin/ obj/ # Legacy code **/Legacy/ **/Old/

Verbose Output

Use the --verbose flag to see which files are being ignored:

csharply organize ./src --verbose # Output will show: # skipped : src/Generated/Model.cs # organized : src/Controllers/UserController.cs
