supersonar 0.3.4

A SonarQube-like static analysis CLI for multi-language repositories.

supersonar

supersonar is a lightweight, SonarQube-inspired static analysis CLI for multi-language repositories. It is designed for local use and CI pipelines via pip install (Python 3.10+).

Supported Languages

• Python
• Java
• JavaScript / React (.js, .jsx, .ts, .tsx)
• Go

Quick start

pip install .
supersonar scan . --format json

Pipeline install (pip)

Use an isolated environment in CI:

python -m venv .venv
. .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install supersonar
supersonar --version
supersonar scan . --format sarif --out reports/supersonar.sarif

Or install from repository source directly:

python -m pip install "git+https://github.com/mortaccio/supersonar.git@main"

The scanner performs real code checks (AST + regex), including:

• dynamic execution (eval/exec)
• broad exception handlers
• subprocess.*(..., shell=True) in Python
• unsafe yaml.load(...) in Python
• cross-language readability checks (line too long, trailing whitespace, oversized file)
• duplicate-code block detection (repeated multi-line chunks)
• Java package naming convention checks (lower.case.package)
• Java type naming convention checks (UpperCamelCase)
• Java class/file naming consistency checks (MyClass in MyClass.java)
• Java method naming convention checks (lowerCamelCase)
• Java constant naming convention checks (UPPER_SNAKE_CASE)
• Java complexity checks (too many method parameters, very long methods, deep nesting)
• Java coupling/cohesion checks (high import fan-out, classes with too many methods, low cohesion)
• Python naming checks (snake_case functions, UpperCamelCase classes)
• Python complexity checks (too many parameters, very long functions, deep nesting)
• Python coupling/cohesion checks (high import fan-out, classes with too many methods, low cohesion)
• JavaScript/React checks (function/component naming, too many parameters, long functions, deep nesting)
• Go checks (package/function naming, too many parameters, long functions, deep nesting, import fan-out)
• hardcoded secret-like assignments
• private key block markers (for example BEGIN ... PRIVATE KEY)
• TODO/FIXME markers
• unresolved merge conflict markers

Python files use AST rules. Other file types use generic cross-language text rules.

CI usage

pip install supersonar
supersonar scan . \
  --format sarif \
  --out reports/supersonar.sarif \
  --fail-on high \
  --max-high 0 \
  --max-critical 0 \
  --coverage-xml coverage.xml \
  --min-coverage 80

Config (supersonar.toml)

[scan]
exclude = [".git", ".venv", "venv", "build", "dist", "__pycache__"]
include_extensions = [".py", ".java", ".js", ".jsx", ".ts", ".tsx", ".go", ".rs", ".cs", ".yaml", ".yml", ".json", ".toml"]
include_filenames = ["Dockerfile", "Jenkinsfile", "Makefile"]
max_file_size_kb = 1024
skip_generated = true
inline_ignore = true
disabled_rules = []
# enabled_rules = ["SS001", "SS003"]
coverage_xml = "coverage.xml"

[quality_gate]
fail_on = "high"
max_issues = 200
max_files_with_issues = 25
max_high = 0
max_critical = 0
min_coverage = 80.0
baseline_report = "reports/supersonar-baseline.json"
only_new_issues = true

[report]
format = "json"

Use CLI overrides when needed:

supersonar scan . --include-ext .java --include-ext .kt --include-file Dockerfile

Quality gates

• fail_on: fail if any issue exists at/above severity
• max_issues: fail if total issues exceed threshold
• max_files_with_issues: fail if number of files with at least one issue exceeds threshold
• max_low, max_medium, max_high, max_critical: per-severity caps
• min_coverage: minimum line coverage percentage from Cobertura XML
• baseline_report + only_new_issues: gate only on issues not present in a previous report

Generate coverage.xml in Python projects with:

python -m pip install coverage
coverage run -m pytest
coverage xml -o coverage.xml

Noise control

• Generated artifacts are skipped by default (target/, .mypy_cache/, .pytest_cache/, .tox/, .nox/, .gradle/, node_modules/, and common binary suffixes).
• Use --include-generated when you explicitly want to scan generated/build outputs.
• Inline suppression is supported per line:
  • # supersonar:ignore ignores all rules on that line.
  • # supersonar:ignore SS001,SS007 ignores specific rules on that line.
• Rule-level controls:
  • --disable-rule SS004 (repeatable)
  • --enable-rule SS001 --enable-rule SS003 (allowlist mode)
