Why InspectCode?

Linters like ESLint, StyleCop or dotnet format check style and syntax - things like naming conventions, missing braces, or unused imports. That's useful, but it's surface-level.

JetBrains InspectCode (the engine behind ReSharper) does deep static analysis of your .NET code. It understands your type system, control flow, and data flow to find bugs that no linter can catch:

• Null reference paths - "this variable can be null here, and you're not checking"
• Dead code detection - "this condition is always false, so this branch never executes"
• Possible InvalidOperationException - "this .Value call on a nullable will throw at runtime"
• Multiple enumeration - "you're iterating this IEnumerable twice, which may cause unexpected behavior or performance issues"
• Virtual calls in constructors - "this overridable method call in a constructor will behave differently in derived classes"

These are runtime bugs waiting to happen that pass every linter, every compiler warning, and every code review. InspectCode finds them before your users do.

The problem: InspectCode produces a raw report (XML or SARIF/JSON) with hundreds of findings. That's where this tool comes in - it gives you an interactive terminal UI to browse, filter, inspect, and fix those findings one by one.

Features

• Horizontal split layout - findings table on the left, source code with syntax highlighting on the right
• Browse findings in a filterable table with severity colors
• Source code view with automatic jump to the affected line
• Run jb inspectcode directly from the TUI with live log and progress indicator
• Git commit mode - only scan files changed since a commit (--commit HEAD~1)
• Auto-fix for 11 issue types with diff preview before applying
• History - remember and reuse recent scan parameters
• Top 10 chart - most frequent finding types, categories, and files at a glance
• 31 retro themes - via theme picker (Ctrl+P), see textual-themes
• Whitelist - ignore known issues via whitelist.json, toggle on/off and add findings directly in the TUI
• Persistent settings - theme, log height and visibility are saved
• Multilingual - German and English, switch with --lang en
• .sln and .csproj - both project types are supported
• XML and SARIF/JSON - both InspectCode output formats are auto-detected

Prerequisites

• Python 3.10+
• JetBrains CLI Tools (jb inspectcode) - install via:

  dotnet tool install -g JetBrains.ReSharper.GlobalTools

Installation

One-Click Install (Standalone, no Python needed)

Windows (PowerShell):

irm https://raw.githubusercontent.com/michaelblaess/inspectcode-tui/main/install.ps1 | iex

Linux / macOS:

curl -fsSL https://raw.githubusercontent.com/michaelblaess/inspectcode-tui/main/install.sh | bash

From Source (Python 3.10+)

git clone https://github.com/michaelblaess/inspectcode-tui.git
cd inspectcode-tui
pip install -e .

Usage

# Run a live scan on a solution
inspectcode-tui "C:\path\to\MySolution.sln"

# Scan a single .csproj
inspectcode-tui "C:\path\to\MyProject.csproj"

# Scan a specific project within the solution
inspectcode-tui "MySolution.sln" --project="MyProject"

# Only scan files changed since last commit (Git mode)
inspectcode-tui "MySolution.sln" --commit HEAD~1

# Load an existing report file (no scan needed)
inspectcode-tui --xml="C:\Temp\inspectcode-results.xml"

# Filter by minimum severity
inspectcode-tui --xml="report.xml" --severity=ERROR

# Build before scanning (default: --no-build)
inspectcode-tui "MySolution.sln" --build

# English UI
inspectcode-tui "MySolution.sln" --lang en

# Start without arguments (history selection)
inspectcode-tui

Tip: Close Visual Studio before running a live scan to avoid file lock errors. The selected language is saved and automatically used on the next start.

How It Works

1. InspectCode analyzes your .NET solution and writes a report (XML or SARIF/JSON)
2. inspectcode-tui auto-detects the format and parses it into structured Finding objects
3. Findings are displayed in a DataTable with severity coloring and filtering
4. Navigating the table automatically shows the source code with the affected line highlighted on the right
5. For fixable issues, you can preview the diff and apply the fix with a single keypress
6. Git is your safety net - all changes can be reverted anytime with git checkout
