filemaptree 0.1.0

Deterministic ASCII file tree renderer

filemaptree

Deterministic ASCII file tree renderer.

Version

0.1.0

Purpose

filemaptree renders a deterministic ASCII file tree. It is a single-purpose tool designed for clean, stable, and reusable directory visualization.

Installation

pip install -e .

Usage

Basic usage

# Current directory
python -m filemaptree.main .

# Specific path
python -m filemaptree.main /path/to/directory

Depth control

# Show only root
python -m filemaptree.main . --depth 0

# Show root + immediate children
python -m filemaptree.main . --depth 1

# Show root + two levels
python -m filemaptree.main . --depth 2

Ignore patterns

# Ignore specific names (exact match)
python -m filemaptree.main . --ignore __pycache__,node_modules,.git

Combined options

python -m filemaptree.main /path/to/repo --depth 3 --ignore .git,node_modules

Features

• Deterministic ordering: Directories first, then files, both alphabetically (case-insensitive)
• Depth control: Limit tree depth with --depth N
• Ignore patterns: Skip specific directory/file names with --ignore
• ASCII rendering: Clean tree structure using ├──, └──, │
• Cross-platform: Stable output across operating systems

Architecture

├── __init__.py    # Package marker
├── main.py        # Entry point
├── cli.py         # Argument parsing and orchestration
├── walker.py      # Directory traversal and tree building
└── renderer.py    # ASCII tree rendering

Separation of concerns

• cli.py: Parses arguments, validates paths, orchestrates flow
• walker.py: Traverses filesystem, applies filters, builds Node tree
• renderer.py: Converts Node tree to ASCII output
