## Overview

`pyproj_dep_analyze` analyzes Python project dependencies declared in `pyproject.toml` files:

- **Parses** dependencies from PEP 621, Poetry, PDM, and Hatch formats
- **Checks** for newer versions on PyPI and GitHub
- **Enriches** with metadata: license, stars, release dates, download stats
- **Outputs** structured JSON with human/LLM-readable recommendations

## Scope & Boundaries

### What `pyproj_dep_analyze` Does

| Capability               | Description                                                    |
|--------------------------|----------------------------------------------------------------|
| **Parse pyproject.toml** | Extract dependencies from PEP 621, Poetry, PDM, Hatch formats  |
| **Check for updates**    | Query PyPI/GitHub for latest compatible versions               |
| **Enrich with metadata** | License, stars, forks, release dates, maintainers              |
| **Version metrics**      | Release frequency, project age, abandonment indicators         |
| **Download statistics**  | Popularity metrics from pypistats.org                          |
| **Index detection**      | Identify which package index serves each dependency            |
| **Direct dependencies**  | Extract immediate dependencies from `requires_dist`            |

### What Belongs in `pyproj_dep_security` (Separate Project)

| Capability                          | Reason                                               |
|-------------------------------------|------------------------------------------------------|
| **Full transitive dependency tree** | Requires installed environment (pipdeptree)          |
| **Vulnerability scanning**          | Security-specific (OSV, Safety DB, Snyk integration) |
| **License compliance checking**     | Policy enforcement, not metadata                     |
| **Dependency confusion detection**  | Active security scanning                             |
| **Supply chain risk scoring**       | Requires vulnerability data + heuristics             |
| **Typosquatting detection**         | Requires name similarity analysis                    |

### What Belongs in `pyproj_dep_update` (Separate Project)

| Capability                    | Reason                                                |
|-------------------------------|-------------------------------------------------------|
| **Update pyproject.toml**     | Modifies project files (write operation)              |
| **Pin indirect dependencies** | Add transitive deps with CVEs to explicit deps        |
| **CVE-driven version bumps**  | Requires vulnerability scan results (Bandit/OSV)      |
| **Generate constraints.txt**  | Create pip constraints for indirect deps              |
| **Batch update operations**   | Update all / security-only / major/minor/patch        |
| **Lock file regeneration**    | Update poetry.lock, pdm.lock, uv.lock after changes   |
| **Update local libraries**    | Bump versions of local/workspace dependencies         |

> **Design Principle:**
> - `pyproj_dep_analyze` analyzes *declared* dependencies from project files
> - `pyproj_dep_security` analyzes *installed* environments (in a venv) for security issues
> - `pyproj_dep_update` *modifies* pyproject.toml based on analysis and security scan results

    github_token=None,          # GitHub API token (default: None)
    timeout=30.0,               # Request timeout in seconds (default: 30.0)
    concurrency=10,             # Max concurrent requests (default: 10)
)

# Filter results
updates = [e for e in entries if e.action == Action.UPDATE]
for entry in updates:
    print(f"{entry.package}: {entry.current_version} -> {entry.latest_version}")
```

#### `run_enriched_analysis()`

Analyze with full metadata enrichment.

)

# Access results
print(f"Total: {result.summary.total_packages}")
print(f"Updates: {result.summary.updates_available}")

for pkg in result.packages:
    print(f"{pkg.name}: {pkg.action.value}")
    if pkg.pypi_metadata:
        print(f"  License: {pkg.pypi_metadata.license}")
    if pkg.repo_metadata:
        print(f"  Stars: {pkg.repo_metadata.stars}")

# Save to file
write_enriched_json(result, "analysis.json")
```

#### `write_outdated_json()` / `write_enriched_json()`

Write analysis results to JSON files.

```python
from pyproj_dep_analyze import (
    analyze_pyproject,
    run_enriched_analysis,
    write_outdated_json,
    write_enriched_json,
)

# Basic analysis
entries = analyze_pyproject("pyproject.toml")
write_outdated_json(entries, "outdated.json")

# Enriched analysis
result = run_enriched_analysis("pyproject.toml")
write_enriched_json(result, "deps_enriched.json")
```

---

### Analyzer Class

For more control, use the `Analyzer` class directly.

```python
from pyproj_dep_analyze import Analyzer
from pathlib import Path

analyzer = Analyzer(
    github_token="ghp_xxxxx",   # GitHub API token (default: None)
    timeout=60.0,               # Request timeout in seconds (default: 30.0)
    concurrency=20,             # Max concurrent requests (default: 10)
)

# Basic analysis
result = analyzer.analyze(Path("pyproject.toml"))
for entry in result.entries:
    print(f"{entry.package}: {entry.action.value}")

# Enriched analysis
enriched = analyzer.analyze_enriched(Path("pyproject.toml"))
```

---

### Index Resolution

Detect and resolve package indexes.

```python
from pyproj_dep_analyze import (
    IndexResolver,
    detect_configured_indexes,
    identify_index,
)

# Detect all configured indexes
indexes = detect_configured_indexes()
for idx in indexes:
    print(f"{idx.url} ({idx.index_type.value}, private={idx.is_private})")

# Identify index type from URL
info = identify_index("https://pypi.org/simple")
print(info.index_type)  # IndexType.PYPI

# Resolve which index serves a package (async)
resolver = IndexResolver(indexes=indexes, timeout=30.0)
index_info = await resolver.resolve("requests")
```

---

### Repository Resolution

Resolve repository metadata from URLs.

```python
from pyproj_dep_analyze import (
    RepoResolver,
    detect_repo_url,
    parse_repo_url,
    PyPIUrlMetadata,
)

# Parse repository URL
parsed = parse_repo_url("https://github.com/psf/requests")
print(f"{parsed.owner}/{parsed.name}")  # psf/requests

# Detect repo URL from PyPI metadata
urls = PyPIUrlMetadata(project_urls={"Source": "https://github.com/psf/requests"})
repo_url = detect_repo_url(urls)

# Fetch repository metadata (async)
resolver = RepoResolver(github_token="ghp_xxx", timeout=30.0)
metadata = await resolver.resolve("psf", "requests")
print(f"Stars: {metadata.stars}")
```

---

stats = await resolver.fetch_stats_async("requests")
if stats:
    print(f"Last month: {stats.last_month_downloads}")
    print(f"Last week: {stats.last_week_downloads}")

# Fetch stats for multiple packages (async)
results = await resolver.fetch_many_async(
    ["requests", "httpx", "pydantic"],
    concurrency=5,

## Data Models

### Enums

#### `Action`

```python
from pyproj_dep_analyze import Action

Action.UPDATE          # "update" - newer version exists
Action.DELETE          # "delete" - remove for this Python version
Action.NONE            # "none" - up to date
Action.CHECK_MANUALLY  # "check manually" - needs manual verification
```
