pip-verv (Version Review) is a read-only CLI tool that audits the temporal freshness of Python dependencies. It measures how long each dependency has been behind the latest stable release on PyPI, calculates a per-package GAP in days, and produces a project-wide Health Score (0–100). It does not install, modify, or resolve environments.

---

Installation

pip install pip-verv

---

Usage

# Audit the current directory
verv --path .

# Output as JSON
verv --format json

# CI: fail if Health Score drops below 70
verv --score-fail 70

# CI: fail if any dependency GAP exceeds 365 days, with max 2 MAJOR-outdated deps
verv --score-fail 70 --gap-fail 365 --max-major 2

# Export to file
verv --format json > audit.json

# Audit only dependencies with a release newer than a date
verv --since 2025-01-01

# Audit explicit files
verv --env requirements.txt --env requirements-dev.txt

# Skip cache
verv --no-cache

---

Supported File Formats

pip-verv auto-discovers and parses dependency declarations from the following sources:

File	Sections parsed
requirements*.txt	All pinned/ranged deps; follows -r includes recursively
pyproject.toml (PEP 621)	[project.dependencies], [project.optional-dependencies.*]
pyproject.toml (PEP 735 / uv)	[dependency-groups.*]
pyproject.toml (Poetry)	[tool.poetry.dependencies], [tool.poetry.group.*.dependencies]

Poetry constraint mapping:

Poetry syntax	PEP 440 equivalent
^1.2.3	>=1.2.3,<2.0.0
^0.2.3	>=0.2.3,<0.3.0
~1.2.3	>=1.2.3,<1.3.0
*	(any version, audited without version filter)

Git, path, and URL dependencies are detected but flagged as not auditable (excluded from the Health Score).

---

CLI Flags

Flag	Description
--path PATH	Project root to scan (default: .)
--env FILE	Explicit source file(s); repeatable; disables auto-discovery
--ignore PKG	Package name(s) to exclude; repeatable
--since DATE	Include only deps whose latest stable release is after YYYY-MM-DD
--format FORMAT	Output format: rich (default), json, csv, md
--no-cache	Disable the file-based PyPI response cache
--score-fail N	Exit non-zero if Health Score < N
--gap-fail N	Exit non-zero if any dependency GAP > N days
--max-major N	Exit non-zero if MAJOR-outdated dependency count > N
--max-outdated N	Exit non-zero if total outdated dependency count > N

---

Output Fields (All Formats)

Each dependency row/object includes:

Field	Meaning
name	Package name
status	up_to_date, outdated, or no_data
installed	Version currently installed in the environment (if present)
latest	Latest stable version available on PyPI
target	Version you should upgrade to now (see below); null if up-to-date or blocked
bump	Semver jump required to reach target (major, minor, patch, or null)
urgency	How pressing the upgrade is (hybrid of time and semver: major, minor, patch, na)
days_behind	Days between your version's release and the latest release
blockers	List of packages whose constraints prevent upgrading to the latest version

target field explained

• Up-to-date: null (nothing to do)
• Outdated, no blockers: latest (upgrade freely)
• Outdated, blocked, can partially upgrade: highest version allowed by environment constraints
• Outdated, blocked at current version: null (already at env ceiling; see blockers)

---

Output Formats

Format	Description
rich	Colour-coded terminal table grouped by urgency, with Health Score summary
json	Machine-readable JSON with score and per-dependency detail
csv	Comma-separated values, one row per dependency
md	Markdown table, suitable for reports or PR comments

All formats include the fields above, in this order:

name, status, installed, latest, target, bump, urgency, days_behind, blockers

---

Health Score

The Health Score (0–100) is the mean of per-package freshness scores:

• Up-to-date: 100%
• Outdated: Linear penalty by urgency:
  • major: 0% at 365 days behind
  • minor: 0% at 730 days
  • patch: 0% at 1460 days
• Unknown freshness: Excluded from average

Formula:

$$ \text{score} = \frac{\sum \text{per-package scores}}{\text{count of known-freshness packages}} $$

Score	Status
90–100	Excellent
70–89	Healthy
50–69	Needs attention
< 50	High risk
