## Diagnostic Configuration

PureSharp uses Roslyn's standard `.editorconfig` mechanism for configuring diagnostic severity. You can control how each diagnostic is reported (error, warning, or suppressed) using the `dotnet_diagnostic.<ID>.severity` setting.

### Supported Diagnostics

| Diagnostic ID | Category | Title | Default Severity |
|---|---|---|---|
| **RT0001** | Purity | Static mutable field access | Error |
| **RT0002** | Purity | Non-pure method call | Error |
| **RT0003** | Purity | I/O operation | Error |
| **LVP0001** | Purity | Reassignment to immutable local variable | Error |
| **LVP0002** | Purity | Immutable local variable missing initializer | Error |
| **LVP0003** | Naming | Naming suggestion for effectively immutable variables | Warning |
| **FIF0001** | FluentIf | FluentIf chain not terminated with .Else() | Error |

### Configuration Example

Create (or update) `.editorconfig` in your project root:

```editorconfig
# .editorconfig

root = true

[*.cs]
# Configure PureSharp diagnostic severities
# Valid values: none, silent, suggestion, warning, error

# Referential Transparency (RT) - default: error
dotnet_diagnostic.RT0001.severity = error
dotnet_diagnostic.RT0002.severity = error
dotnet_diagnostic.RT0003.severity = error

# Local Variable Purity (LVP) - default: error/warning
dotnet_diagnostic.LVP0001.severity = error
dotnet_diagnostic.LVP0002.severity = error
dotnet_diagnostic.LVP0003.severity = warning

# FluentIf (FIF) - default: error
dotnet_diagnostic.FIF0001.severity = error
```

### Severity Levels

- **error**: Build fails if the diagnostic is triggered
- **warning**: Displays a warning but build succeeds

Microsoft Roslyn analyzer diagnostics TreatWarningsAsErrors WarningsAsErrors official documentation

💡 Result:

To manage how Microsoft Roslyn analyzer diagnostics are treated as errors in a.NET project, you can use several MSBuild properties in your project file (.csproj) or configure individual rule severities via EditorConfig files [1][2][3]. MSBuild Properties The following MSBuild properties control build-time behavior for warnings: 1. TreatWarningsAsErrors: When set to true in a PropertyGroup, all warnings (including compiler warnings and Roslyn analyzer diagnostics) are treated as errors, causing the build to fail [4][5]. true 2. WarningsAsErrors: Allows you to specify a comma-separated list of specific warning IDs (e.g., CA1822) to be treated as errors, even if TreatWarningsAsErrors is not globally enabled [4][6]. CA1822,IDE0001 3. CodeAnalysisTreatWarningsAsErrors: If you have enabled global warning-to-error behavior but want to exempt Roslyn analyzer diagnostics (CAxxxx), you can set this property to false [3][6]. false EditorConfig Configuration For more granular control over specific rules, you can use an.editorconfig file. This is the recommended approach for configuring individual analyzer diagnostic severities [1][7]. By setting the severity to error, the diagnostic will fail the build regardless of global MSBuild warning settings [1][2][8]. dotnet_diagnostic..severity = error Summary of Behavior - Global Settings: Use TreatWarningsAsErrors or WarningsAsErrors in the project file to impact all or specific warnings project-wide [4][6]. - Per-Rule Settings: Use.editorconfig to set individual rule severities to error, warning, suggestion, silent, or none [1][2][8]. - Precedence: When multiple settings conflict, rule-specific severity settings typically take precedence over global MSBuild warning switches [1][8]. If you encounter issues with analyzer warnings being treated as errors, ensure CodeAnalysisTreatWarningsAsErrors is configured as desired [3].

site:learn.microsoft.com CodeAnalysisTreatWarningsAsErrors TreatWarningsAsErrors analyzer warnings WarningsAsErrors

💡 Result:

In.NET, analyzer warnings and project-level "treat warnings as errors" settings are closely related but managed through distinct mechanisms. 1. TreatWarningsAsErrors The MSBuild property true is a global compiler flag [1]. When enabled, it instructs the compiler to treat all warnings generated by the build as errors, which causes the build to fail [1]. 2. CodeAnalysisTreatWarningsAsErrors If you have enabled globally but want to exclude code analysis (CAxxxx) warnings from causing build failures, you can set false in your project file [2]. This allows code analysis warnings to appear in your build logs without breaking the build [2]. 3. Managing Severity Directly While the properties above control whether warnings halt the build, you can manage the behavior of individual rules or categories of rules more granularly using an EditorConfig or global AnalyzerConfig file [3][4]. By setting a rule's severity to error, you ensure it always causes a build failure, regardless of your global setting [4]: dotnet_diagnostic.<rule_id>.severity = error Precedence and Best Practices: * Compiler Options: Command-line options like -warnaserror always override severity settings specified in EditorConfig or global AnalyzerConfig files [3]. * Modern Approach: Microsoft recommends using EditorConfig files for modern.NET development, as they provide more precise, file-system-aware configuration compared to legacy rule-set files [3][4]. * Avoiding Conflicts: If you are migrating legacy code analysis or experiencing unexpected build errors, explicitly setting false is the standard way to decouple analyzer output from your main compiler warning policy [5][2].

- **suggestion**: Minor suggestion (often used for code quality hints)
- **silent**: Suppresses the diagnostic from output but analysis still runs
- **none**: Completely suppresses the diagnostic

### Example: Suppressing a Diagnostic

```editorconfig
[*.cs]
# Suppress LVP0003 (naming suggestions)
dotnet_diagnostic.LVP0003.severity = none
```

## Motivation for Development
C# is a very powerful language, but in large-scale development or complex logic, debugging can become difficult due to unintended side effects or variable reuse. PureSharp was born to provide developers with "freedom (from bugs)" in the form of "constraints."

## 診断の設定

PureSharp は Roslyn 標準の `.editorconfig` 機構を使用して、診断の重大度を設定します。`dotnet_diagnostic.<ID>.severity` 設定で、各診断をエラー、警告、または抑制として報告することができます。

### サポートされている診断

| 診断ID | カテゴリー | タイトル | 既定の重大度 |
|---|---|---|---|
| **RT0001** | Purity | 静的可変フィールドへのアクセス | エラー |
| **RT0002** | Purity | 非純粋メソッドの呼び出し | エラー |
| **RT0003** | Purity | I/O操作 | エラー |
| **LVP0001** | Purity | 不変ローカル変数への再代入 | エラー |
| **LVP0002** | Purity | 不変ローカル変数の初期化忘れ | エラー |
| **LVP0003** | Naming | 効果的に不変な変数の命名提案 | 警告 |
| **FIF0001** | FluentIf | FluentIf チェーンの .Else() での終端忘れ | エラー |

### 設定例

プロジェクトのルートに `.editorconfig` を作成（または更新）します：

```editorconfig
# .editorconfig

root = true

[*.cs]
# PureSharp の診断重大度を設定
# 有効な値: none, silent, suggestion, warning, error

# 参照透過性 (RT) - 既定: error
dotnet_diagnostic.RT0001.severity = error
dotnet_diagnostic.RT0002.severity = error
dotnet_diagnostic.RT0003.severity = error

# ローカル変数の不変性 (LVP) - 既定: error/warning
dotnet_diagnostic.LVP0001.severity = error
dotnet_diagnostic.LVP0002.severity = error
dotnet_diagnostic.LVP0003.severity = warning

# FluentIf (FIF) - 既定: error
dotnet_diagnostic.FIF0001.severity = error
```

### 重大度レベル

- **error**: 診断が検出された場合ビルドが失敗します
- **warning**: 警告が表示されますがビルドは成功します
- **suggestion**: コード品質の軽微な提案（IDE内でハイライトされます）
- **silent**: 診断が出力から抑制されますが分析は実行されます
- **none**: 診断が完全に抑制されます

### 例：診断を抑制する

```editorconfig
[*.cs]
# LVP0003（命名提案）を抑制
dotnet_diagnostic.LVP0003.severity = none
```

---

## 開発の動機
C# は非常に強力な言語ですが、大規模な開発や複雑なロジックにおいて、意図しない副作用や変数の再利用が原因でデバッグが困難になることがあります。PureSharp は、開発者に「制約」という名の「自由（バグからの解放）」を提供するために生まれました。

Define the ConsumerApp build contract.

RT0001 is an error, so the annotated _globalCache access makes a Debug build fail when the analyzer is available. The project hard-codes the Debug analyzer path, and ConsumerApp is not in PureSharp.slnx. If this is a runnable example, remove or isolate the violation. Otherwise, document the expected failed build and configure analyzer loading for each build configuration.

Use the active build configuration for the analyzer path.

Line 22 hard-codes bin/Debug. A Release build places the project-reference output under bin/Release, so the analyzer is not reliably loaded. Use $(Configuration) or an MSBuild project-reference analyzer item.

Proposed fix 
-      <Analyzer Include="../../src/PureSharp.Core/bin/Debug/netstandard2.0/PureSharp.Core.dll" Visible="false" />
+      <Analyzer Include="../../src/PureSharp.Core/bin/$(Configuration)/netstandard2.0/PureSharp.Core.dll" Visible="false" />

- 22, Update the AddAnalyzers target’s Analyzer Include path to use the active
MSBuild configuration via $(Configuration) instead of the hard-coded Debug
directory, so both Debug and Release builds resolve PureSharp.Core.dll
correctly.

// =========================================================
// 注記: Roslyn 標準 .editorconfig による severity 制御テスト
//
// Roslyn標準のDiagnosticOptions機構はAnalyzer側では自動的に機能します。
// .editorconfig での severity 設定は、Roslyn が解析時に自動的に適用するため、
// Analyzer 実装の側で特別な対応は不要です。
//
// consumer project での実際の .editorconfig 設定を通じた統合テストを推奨します。
// （テストプロジェクトのスコープ外で検証）

Add executable .editorconfig severity integration coverage.

The consumer app is not included in PureSharp.slnx or CI. Its configuration covers only error and warning, and most diagnostic triggers are commented out. Add tests or CI validation for error, warning, none, independent diagnostic IDs, and .editorconfig scope.

lines 200 - 210, Add executable integration coverage for the analyzer’s
.editorconfig severity behavior, including error, warning, and none settings,
independent diagnostic IDs, and configuration scope across applicable consumer
projects. Implement this in the test or CI path used by PureSharp.slnx rather
than relying on the excluded consumer app, and ensure the scenarios contain
active diagnostic triggers.
