drace 2.0.6

A pragmatic, resilient Python linter and formatter

Drace – The Pragmatic Linter & Formatter

Drace is a resilient, opinionated, and user-centric linter + formatter for Python. It doesn't just enforce convention — it encourages better code thinking, inspired by The Pragmatic Programmer and real-world software philosophies.

---

Features

• Resilient Parsing: Drace won't crash on fatal syntax errors — it continues linting and shows where things broke
• Custom Linting Rules: Includes pragmatic and aesthetic rules like:
  • Z200: Suggests one-liners where appropriate
  • Z202: Suggests refactoring for DRY-ness
  • Z221: Warns about bloated functions
  • Z222: Flags high external dependency usage
• AST-based & Rule-based Checks: Deep analysis where needed, quick rules where not
• Formatter Included: Drace has a formatter with opinionated but readable output
• User-Friendly Config System:
  • Supports CLI and interactive (USSD-like) editing
  • Temporary overrides and persistent defaults
• Readable Output:
  • Colored, well-padded output for clarity
  • Aligns messages visually for fast scanning

Installation

pip install drace

Usage

Linting & Formatting

drace lint path/to/file.py       # Lint a file
drace format path/to/file.py     # Format a file
drace                            # Defaults to linting current directory

Scoring Code Quality

drace score path/to/dir

Calculates a "Darkian Standard" score based on lines vs issues.

Configuration

drace config                    # Launch interactive (USSD-style) config
drace config line_len 100       # Set line length limit
drace config list               # View current config
drace config reset              # Reset all defaults
drace config reset line_len     # Reset a key

Drace allows multiple separator styles: =, :, ::, etc:

drace config line_len = 100

Philosophy

Drace is pragmatic-first. It values readability, clarity, and real-world coding sensibilities over strict adherence to PEP8. It helps you write code that's both clean and thoughtful.

Unlike tools like flake8 or black, Drace:

• Handles broken files gracefully
• Suggests deeper improvements (e.g., cohesion, function size)
• Doesn't treat aesthetics and logic as separate

---

Limitations

• Slower than others: Due to deep AST analysis and graceful error handling, Drace may take its time (about 2 seconds longer) on large, nested files
• Currently Python-only: But support for other languages might arrive as I learn them (Go will probably be supported soon)
• Opinionated: May conflict with pure PEP8 setups
