n0conflict 1.0.0

AI-powered Git merge conflict resolver

n0conflict

AI-powered Git merge conflict resolver.

n0conflict resolves Git merge conflicts using AI. Instead of forcing one side over the other, it reads both versions of the conflicting code and produces a single output that preserves the intent of each. When a conflict truly cannot be resolved automatically, it tells you why.

---

Features

• Intelligent merging — understands the intent of both sides, not just the text
• Honest failures — explains clearly when a conflict cannot be auto-resolved
• Multi-language aware — detects Python, TypeScript, Go, Rust, and more
• Three commands — resolve, scan, and explain
• Safe by default — never writes to disk unless you pass --write

---

Installation

pip install n0conflict

Requires Python 3.10+.

---

Configuration

n0conflict uses the Anthropic API. Set your key in the environment before running:

export ANTHROPIC_API_KEY="sk-ant-..."

Alternatively, use N0CONFLICT_API_KEY if you prefer to keep it separate.

---

Usage

Resolve conflicts in a file

# Preview what the resolved file would look like
n0conflict resolve src/app.py --dry-run

# Write the resolved file in place
n0conflict resolve src/app.py --write

Scan a repository for conflicted files

n0conflict scan
n0conflict scan /path/to/repo

Inspect conflicts without resolving

n0conflict explain src/app.py

Other

n0conflict --version
n0conflict --help

---

Example

$ n0conflict resolve app.py --write

n0conflict — app.py
  Found 2 conflict block(s)

  ✓ Conflict 1: Conflict resolved successfully.
  ✓ Conflict 2: Conflict resolved successfully.

✓ Written to app.py

When a conflict cannot be resolved:

  ✗ Conflict 1: cannot be resolved automatically

  │ Both sides remove the authentication middleware but replace it with        │
  │ incompatible implementations — one using JWT, the other using sessions.    │
  │ Keeping both would cause duplicate request handling.                       │
