developer-utility-toolkit 0.1.3

Security-focused modular developer multi-tool CLI.

Developer Utility Toolkit

Security-focused, modular, format-aware Python CLI for common developer tasks.

Features

• Automatic input detection for text, JSON, XML, Base64, URL, and file extension types
• Direct format conversion using a plugin-based transformer registry
• JSON and XML formatting, minification, and validation
• Encoding tools (Base64 and URL encode/decode)
• Binary/Hex/Text/Base64 conversion utilities
• Interactive conversion mode (choose format by number/letter and print all direct outputs)
• Image pixelation utility (optional pillow)
• Sitemap generator and sitemap fetcher with URL validation and request timeouts
• Local command history (~/.developer_utility_toolkit/history/history.jsonl)

Architecture

• src/toolkit/core: abstractions, registry, detector, and safe I/O helpers
• src/toolkit/transformers: pluggable one-step transformers
• src/toolkit/formatters: JSON/XML format/minify/validate services
• src/toolkit/image_tools: image utilities
• src/toolkit/web_tools: sitemap generation/fetching
• src/toolkit/history: local history service
• src/toolkit/cli.py: Typer entrypoint and command wiring

Design choices:

• No chained transformations by default (one direct transform per request target)
• Safe XML parsing via defusedxml
• Controlled output writes via sanitized filename + output directory constraints
• Clear failure modes with explicit non-zero exit codes

Installation

Install from PyPI:

python -m pip install --upgrade pip
pip install developer-utility-toolkit

Install with all optional features:

pip install "developer-utility-toolkit[all]"

Install isolated with pipx (recommended for CLI tools):

pipx install developer-utility-toolkit

Docker (Alternative Install)

Install via GitHub Packages container (GHCR):

docker pull ghcr.io/artenisalija/developer-utility-kit:latest

Run help:

docker run --rm ghcr.io/artenisalija/developer-utility-kit:latest --help

Run a command with mounted files:

docker run --rm -v "$PWD:/work" -w /work ghcr.io/artenisalija/developer-utility-kit:latest format --kind json --file input.json --output output.json

Install developer tooling:

pip install ".[all,dev]"

Usage

toolkit analyze --text '{"name":"dev"}'
toolkit convert --from text --to base64 --text "hello"
toolkit convert-all --text "hello" --from text
toolkit convert-all --text "hello" --ask
toolkit interactive
toolkit hash-all --text "hello"
toolkit hash-all --text "01101000 01101001" --from binary
toolkit format --kind json --text '{"b":2,"a":1}'
toolkit validate --kind xml --text '<root><a>1</a></root>'
toolkit minify --kind json --text '{"b":2,"a":1}'
toolkit image pixelate --input-file ./input.png --output-name output.png
toolkit sitemap generate --base-url https://example.com --path / --path /docs
toolkit sitemap fetch --url https://example.com/sitemap.xml
toolkit recent show --limit 10

Security Philosophy

• Secure defaults and explicit input validation
• Defused XML parser to prevent XXE/entity expansion attacks
• No eval/exec usage
• Timeout-controlled network calls
• Sanitized output file names with constrained output directories
• Graceful errors with explicit status codes

Development

Run local quality gates:

ruff check .
black --check .
mypy src tests
pytest
bandit -r src -ll
pip-audit --strict
safety check --full-report

Pre-commit:

pre-commit install
pre-commit run --all-files

CI/CD

• ci.yml: lint + format + mypy + tests + coverage (>=85%) on Python 3.11/3.12
• security.yml: Bandit + pip-audit + Safety
• release.yml: runs on version tags (v*.*.*), builds wheel/sdist, runs tests, publishes to PyPI, creates GitHub release notes
• ghcr.yml: builds and publishes multi-arch Docker images to GHCR (ghcr.io/artenisalija/developer-utility-kit)
• Dependabot enabled for Python packages and GitHub Actions
