zerv check - zerv

zerv check [OPTIONS] <VERSION>

Validate that a version string conforms to a format. Without --format, zerv checks every supported format and reports each match.

# Check complex SemVer format validation
zerv check --format semver 1.0.0-rc.1.something.complex+something.complex
# → Version: 1.0.0-rc.1.something.complex+something.complex
#   ✓ Valid SemVer format (test case 1)

# Check PEP440 format validation with build metadata
zerv check --format pep440 1.0.0a2.post5.dev3+something.complex
# → Version: 1.0.0a2.post5.dev3+something.complex
#   ✓ Valid PEP440 format (test case 2)

# Check PEP440 format validation with normalization
zerv check --format pep440 1.0.0-alpha.2.post.5.dev.3+something.complex
# → Version: 1.0.0-alpha.2.post.5.dev.3+something.complex
#   ✓ Valid PEP440 format (normalized: 1.0.0a2.post5.dev3+something.complex) (test case 3)

# Invalid version handling (fails with exit code 1)
zerv check --format semver invalid
# → Error: Invalid version: invalid - Invalid SemVer format (test case 4)

# Auto-detect and validate multiple formats
zerv check 2.1.0-beta.1
# → Version: 2.1.0-beta.1
#   ✓ Valid PEP440 format (normalized: 2.1.0b1)
#   ✓ Valid SemVer format (test case 5)

Options

Option	Description
`-f, --format <FORMAT>`	Validate against one format (`semver`, `pep440`); omit for auto-detect

Exit codes

0 - the version is valid in at least the requested (or any detected) format
1 - invalid: the string matches no requested/supported format

Use it as a CI guard for version strings produced elsewhere:

zerv check "1.2.3-rc.2"
# Version: 1.2.3-rc.2
# ✓ Valid PEP440 format (normalized: 1.2.3rc2)
# ✓ Valid SemVer format
