CLI tool to assert that files contain no inline directives

assert-no-inline-directives

A CLI tool to assert that files contain no inline directives for yamllint, pylint, mypy, and coverage.

Installation

pip install assert-no-inline-directives

Usage

assert-no-inline-directives --tools TOOLS [OPTIONS] PATH [PATH ...]

Required Arguments

• --tools TOOLS - Comma-separated list of tools: coverage,mypy,pylint,yamllint
• PATH - One or more file paths, directory paths, or glob patterns to scan (directories are scanned recursively, globs support hidden directories)

Optional Arguments

• --exclude PATTERNS - Comma-separated glob patterns to exclude files
• --quiet - Suppress output, exit code only
• --count - Print finding count only
• -v, --verbose - Show tools, files scanned, findings, and summary
• --fail-fast - Exit on first finding
• --warn-only - Always exit 0, report only
• --allow PATTERNS - Comma-separated patterns to allow

Examples

# Check for pylint and mypy suppressions in files
assert-no-inline-directives --tools pylint,mypy src/*.py

# Scan a directory recursively
assert-no-inline-directives --tools pylint,mypy src/

# Use glob patterns (including hidden directories like .github)
assert-no-inline-directives --tools yamllint "**/*.yml" "**/*.yaml"

# Check all tools, exclude vendor files
assert-no-inline-directives --tools coverage,mypy,pylint,yamllint \
    --exclude "*vendor*" src/ config/

# Allow specific type: ignore patterns
assert-no-inline-directives --tools mypy \
    --allow "type: ignore[import]" src/*.py

# Check for coverage pragmas
assert-no-inline-directives --tools coverage src/

# CI mode: quiet, just exit code
assert-no-inline-directives --tools pylint,mypy --quiet src/

# Verbose mode: show progress
assert-no-inline-directives --tools pylint,mypy --verbose src/

# Non-blocking check (always exit 0)
assert-no-inline-directives --tools mypy --warn-only src/

Exit Codes

• 0 - No inline directives found
• 1 - One or more inline directives found
• 2 - Usage or runtime error (e.g., file not found, invalid tool)

Output Formats

Default format (one finding per line):

src/example.py:10:pylint:pylint: disable
src/example.py:15:mypy:type: ignore
src/example.py:20:coverage:pragma: no cover
config.yaml:5:yamllint:yamllint disable

Count format (--count):

2

Detected Directives

coverage

• pragma: no cover
• pragma: no branch

mypy (suppressions only)

• type: ignore (including bracketed forms like type: ignore[attr-defined])
• mypy: ignore-errors

pylint (suppressions only)

• pylint: disable
• pylint: disable-next
• pylint: disable-line
• pylint: skip-file

yamllint (suppressions only)

• yamllint disable-line
• yamllint disable
• yamllint disable-file

Matching Behavior

• Case-insensitive matching
• Tolerates extra whitespace (e.g., pylint: disable, type: ignore)
• Only detects directives in comments (after #), not in string literals
• Does not flag "enable" directives (e.g., yamllint enable)
• Files are scanned in alphabetical order for consistent output
• Glob patterns support hidden directories (e.g., .github)
• Tools only check files with matching extensions:
  • coverage: .py, .toml
  • mypy: .py, .toml
  • pylint: .py, .toml
  • yamllint: .yaml, .yml, .toml
