[1.2.2] - 2026-01-06

Security & Compatibility Patch

This release hardens symlink handling, preserves secret masking for large files, and removes pathspec deprecation warnings.

Fixed

• CRITICAL: Prevented symlinked directory traversal from escaping root when --follow-symlinks is enabled
• CRITICAL: Large inputs are now masked in chunks instead of bypassing masking entirely
• COMPAT: PathSpec matching uses gitignore engine to avoid deprecation warnings

Changed

• Updated internal version markers to 1.2.2

[1.2.1] - 2025-12-18

Security & Reliability Patch

This release addresses critical security and reliability issues identified in the SIDRCE Spicy Audit.

Fixed

CRITICAL: Markdown Fence Injection (Issue #5)

• Problem: File content containing triple backticks (```) could break markdown output and potentially inject misleading content
• Solution: Implemented dynamic fence escaping that counts consecutive backticks in content and uses N+1 backticks for outer fence
• Impact: Prevents markdown structure corruption and potential injection attacks
• Files: src/dir2md/markdown.py

HIGH: Subprocess RCE Vector (Issue #1)

• Problem: vulture subprocess call created RCE vector if malicious binary in PATH + unreliable dependency on external tool
• Solution: Removed subprocess.run() call entirely; documented future approach using AST or library API
• Impact: Eliminates security risk and removes unreliable external dependency
• Files: src/dir2md/spicy.py

MEDIUM: Silent Exception Failures (Issue #2)

• Problem: try-except-pass blocks silently ignored .env loading failures, making debugging impossible
• Solution: Replaced bare except Exception: pass with specific exception handling (OSError, UnicodeDecodeError) and logging.warning()
• Impact: Users now see warnings when configuration loading fails
• Files: src/dir2md/cli.py

LOW: Aggressive Glob Expansion (Issue #3)

• Problem: Auto-expansion of patterns (e.g., foo/ → [foo/, foo/**, **/foo, **/foo/**]) violated user intent and caused performance issues in large repos
• Solution: Removed automatic expansion; now respects gitignore standard (foo/ means foo/, **/foo for recursive)
• Impact: Better performance, predictable behavior, respects principle of least surprise
• Files: src/dir2md/walker.py

LOW: Hardcoded DEFAULT_EXCLUDES (Issue #4)

• Problem: 20+ hardcoded exclude patterns with personal preferences (.pytest_cache_local) and no easy way to customize
• Solution: Moved to external defaults.json file, removed personal preferences, added graceful fallback
• Impact: Easier maintenance, user can modify excludes by editing JSON file, cleaner codebase
• Files: src/dir2md/cli.py, src/dir2md/defaults.json (new)

Added

• Configuration File: src/dir2md/defaults.json - External default exclusion patterns
• Package Data: Configured pyproject.toml to include defaults.json in distribution
• Priority System: Three-tier exclusion pattern priority (user > project > system)
  • System defaults: defaults.json or custom file via --defaults-file
  • Project config: pyproject.toml [tool.dir2md] excludes = [...]
  • User CLI: --exclude-glob (highest priority)
• CLI Argument: --defaults-file - Specify custom defaults.json path
• pyproject.toml Support: [tool.dir2md.excludes] - Project-level default excludes

Removed

• External tool dependency: vulture subprocess execution (security risk)
• Unused imports: subprocess, shutil from spicy.py
• Personal preferences: .pytest_cache_local from default excludes
• Aggressive glob expansion: Non-glob patterns no longer auto-expanded

Changed

• Glob pattern handling now respects user intent per gitignore standard
• Default excludes now loaded from JSON file with graceful fallback
• Exclusion pattern system redesigned with three-tier priority (backwards compatible)

Notes

• All fixes maintain backward compatibility
• No breaking changes to CLI interface
• Users who relied on auto-glob expansion should explicitly use **/pattern for recursive matching
• Files containing ``` now render correctly (markdown fence escaping)

Usage Examples

Priority System:

# System defaults only (defaults.json)
dir2md .

# Custom system defaults
dir2md . --defaults-file my-defaults.json

# Project + system defaults (pyproject.toml overrides system)
# In pyproject.toml:
# [tool.dir2md]
# excludes = ["*.log", "temp/"]

# User overrides everything (highest priority)
dir2md . --exclude-glob "secret-data/"

pyproject.toml Configuration:

[tool.dir2md]
excludes = [
    "*.log",
    "temp/",
    "cache/",
    "*.tmp"
]
# These patterns will be added to system defaults
# User CLI args (--exclude-glob) take precedence over these

[1.2.0] - 2025-12-15

Philosophy: Intelligence Without Complexity

This release removes configuration overhead while adding sophisticated optimizations. All features auto-activate based on preset choice - zero flags, maximum intelligence.

Added

Phase 1: Gravitas Compression (SAIQL-Inspired)

• Symbolic Compression: Unicode symbol substitution reduces tokens by 30-50%
  • Basic level: Common metadata patterns (File: → §, Lines: → ⊞)
  • Medium level: + File type symbols (.py → 🐍, .js → 📜)
  • Full level: + Code patterns (function → ƒ, class → ©)
• Auto-Activation: pro preset = basic, ai preset = medium
• Stats Reporting: Compression statistics embedded as HTML comments in output

Phase 2: Smart Query Processing

• Typo Auto-Correction: Levenshtein distance-based correction
  • 80+ programming term dictionary (auth, payment, database, API, etc.)
  • Automatic suggestions: "atuh" → "auth", "databse" → "database"
  • Zero-dependency implementation
• Query Expansion: Pattern-based synonym expansion
  • 50+ domain-specific patterns
  • Accuracy improvement: 60% → 90%
  • Example: "auth" → "auth OR login OR signin OR session OR token"
• Query Suggestions: File-based keyword extraction
  • Analyzes matched files for related terms
  • Directory-grouped suggestions
  • Query history tracking
• Auto-Activation: Enabled when --query provided

Phase 3: AST Semantic Sampling

• Python Structure Extraction: Intelligent code sampling using AST analysis
  • Priority-based extraction: Classes > Functions > Implementation
  • Preserves: Class definitions, function signatures, docstrings
  • Reduces: Implementation details, private methods
  • Additional 30-40% token reduction
• NodePriority System:
  • CRITICAL: Public classes, main/entry functions
  • HIGH: Public functions, class methods
  • MEDIUM: Private functions
  • LOW: Implementation details
• Auto-Activation: Enabled for .py files in pro/ai presets
• Fallback: Gracefully handles unparseable files

Changed

Radical Simplification

• REMOVED: --gravitas flag (now preset-based)
• REMOVED: --expand flag (now auto-enabled with queries)
• Preset Behaviors:
  • raw: No optimizations (pure original)
  • fast: No optimizations (minimal metadata)
  • pro: gravitas=basic + query expansion + AST sampling
  • ai: gravitas=medium + query expansion + AST sampling

Architecture

• New Modules:
  • src/dir2md/query/corrector.py (180 lines) - Typo correction engine
  • src/dir2md/query/suggester.py (180 lines) - Query suggestion engine
  • src/dir2md/samplers/semantic.py (320 lines) - AST semantic sampler
• Pipeline Integration: Semantic sampling integrated into selector.py file processing
• Zero Dependencies: All features implemented without external LLM or NLP libraries

Performance

Combined Optimizations

• Token Reduction: Up to 60-70% total savings
  • Gravitas: 30-50% (preset-dependent)
  • AST Sampling: 30-40% (for Python files)
  • Cumulative effect on Python codebases
• Query Accuracy: 60% → 90% (pattern expansion)
• User Experience: 2 flags instead of 7 for common use cases

Documentation

• README: Completely rewritten to emphasize zero-configuration intelligence
• Examples: Simplified from 7-flag commands to 2-flag commands
• Migration Guide: Clear before/after examples for v1.1.3 → v1.2.0

Testing

• Phase 1: 4/4 preset configurations validated
• Phase 2: Typo correction tested with 7+ common mistakes
• Phase 3: AST sampling validated on real Python modules (31% reduction achieved)
• Integration: All phases tested together in production scenarios

Breaking Changes

None - All changes are additive or simplify existing behavior. Users on raw preset see no changes.

[1.1.2] - 2025-12-09

Security

• Masking now pre-compiles basic/advanced regexes and skips processing when input exceeds a safe threshold to reduce ReDoS risk.
• Large individual files are skipped before read when they exceed 1MB, preventing OOM/hangs while still noting the skip.

Performance

• Token estimation is cached with LRU (maxsize 2048) and keeps a minimum of one token for empty strings.

Behavior/UX

• Skipped oversized files now record placeholder hash/summary so the skip is visible in outputs and manifests.
• Custom masking patterns are compiled before use; invalid patterns emit warnings and are ignored.

Tests

• Pytest suite: 22 passed, 2 skipped.

[1.1.1] - 2025-12-04

[1.1.1] - 2025-12-04

Removed

• Pro/license gating entirely: deleted license.py, removed license checks from masking/parallel/CLI/tests; .env.example no longer includes license keys.
• Blueprint workflow retired; CI now runs ruff + pytest only.

Fixed

• HF demo import path includes src so dir2md imports resolve in Spaces.
• Lint/test cleanup after refactor (ruff + pytest green).

Documentation

• Updated README/demo metadata (Spicy branding, HF front matter); pending: scrub remaining Pro/license mentions in docs.
