ROSE - Yet Another ROS Bag Filter

inspired by rosbag_editor

Aesthetic

The cassette tape, a modest analog artifact, has evolved into a retro-futurism icon, demonstrating that technological advancement can coexist with human touch. Its tactile interface and physical limitations serve as poignant reminders of our technological heritage.

磁带盒不仅是一种技术遗物，更是复古未来主义的艺术品和精神图腾。简单的按钮、褪色的塑料外壳和有限的存储容量，既是怀旧的载体，也是对数字霸权的温柔反抗。它时刻提醒着我们：技术的突飞猛进不应该以牺牲人性为代价，克制的设计往往更能打动人心。

The interface embraces the cassette futurism aesthetic - a design philosophy that reimagines future interfaces through the lens of 20th century technological fossils. This intentional retrofuturism features:

  • Nostalgic minimalism: Low-resolution displays and monochromatic schemes that evoke 1980s computing
  • Tactile authenticity: Visual metaphors of physical media like magnetic tapes and CRT textures
  • Humanized technology: Warm color palettes and "imperfect" interfaces that resist digital sterility

More than mere retro styling, this approach serves as poetic resistance to digital hegemony. The cassette tape - our central metaphor - embodies this duality:

Key Features

  • 🎉 ROS Environment independent using rosbags
  • 🌟 Command-line interface for automation
  • Filter ROS bag files
    • 🌟 Interactive Mode (-i): Fuzzy search and multi-select topics for extraction
    • with topic selection (fuzzy matching supported via --topic in inspect)
    • with manually selected topics
    • by time range (available in extract command)
  • 🌟 Bag file compression support - Reduce file sizes significantly
    • BZ2 compression (best compression ratio)
    • LZ4 compression (faster compression/decompression)

Getting Started

Installation

Option 1: Install from PyPI

pip install rose-bag

Option 2: Install from Source

# Clone the repository
git clone https://github.com/hanxiaomax/rose.git
cd rose

# Install dependencies
pip install -r requirements.txt

Option 3: Docker Installation

For cross-platform usage or isolated environments:

# Clone the repository
git clone https://github.com/hanxiaomax/rose.git
cd rose

# Build Docker image
./docker/build.sh

# Run Rose in Docker container
./docker/go_docker.sh

The Docker container includes:

  • All required dependencies pre-installed
  • ROS bag processing libraries (rosbags, rosbag)
  • Volume mounting for accessing local bag files

Docker Usage Examples:

# After running ./docker/go_docker.sh, you're inside the container

# Process bag files in your mounted directory
rose load *.bag
rose inspect demo.bag
rose inspect demo.bag --topic /gps/fix  # Inspect specific topic (Tree view or TUI)
rose extract input.bag --topics gps imu
rose extract *.bag -i                   # Interactive extract (Fuzzy search)

To uninstall Rose, run:

pip uninstall rose-bag

Terminal Setup

To ensure proper color display in your terminal, set the following environment variable:

# Add this to your bashrc or zshrc
export TERM=xterm-256color

No ROS bag file? No problem! Download webviz demo.bag and give it a try!

Usage

Rose provides a comprehensive set of CLI commands for ROS bag file operations.

# Show all available commands
rose --help

# Show help for specific command
rose <command> --help

Available Commands

Command Description
load Load bag files into cache for faster operations
extract Extract specific topics from bag files
compress Compress bag files with different algorithms
inspect Inspect bag file contents and statistics
list List and manage cached bag files
config Manage configuration

Load Command

Load bag files into cache for faster subsequent operations:

# Load all bag files in current directory
rose load "*.bag"

# Load specific files
rose load bag1.bag bag2.bag

# Load with parallel processing
rose load "*.bag" --workers 4

# Force reload even if cached
rose load "*.bag" --force

# Build message index for deeper analysis (slower load)
rose load "*.bag" --build-index

# Preview what would be loaded
rose load "*.bag" --dry-run

Extract Command

Extract specific topics from bag files:

# Extract from all bag files
rose extract "*.bag" --topics gps imu

# Extract from single file with output pattern
rose extract input.bag --topics /gps/fix -o "{input}_filtered.bag"

# Extract from multiple files, exclude topics
rose extract bag1.bag bag2.bag --topics tf --reverse

# Parallel extraction with compression
rose extract "*.bag" --topics gps --compression lz4 --workers 4

# Preview without extraction
rose extract "*.bag" --topics gps --dry-run

Options:

  • --topics: Topics to keep (supports fuzzy matching, use multiple times)
  • --reverse: Exclude specified topics instead of including them
  • --compression: Compression type (none, bz2, lz4)
  • --output, -o: Output pattern (use {input} for filename, {timestamp} for timestamp)
  • --workers, -w: Number of parallel workers
  • --dry-run: Preview without executing
  • --yes, -y: Answer yes to all prompts

Compress Command

Compress bag files with different algorithms:

# Compress all bag files with LZ4
rose compress "*.bag" --compression lz4

# Compress single file with BZ2
rose compress input.bag --compression bz2 -o "{input}_{compression}.bag"

# Parallel compression
rose compress bag1.bag bag2.bag --compression lz4 --workers 4

# Preview compression
rose compress "*.bag" --compression bz2 --dry-run

Options:

  • --compression, -c: Compression type (bz2, lz4) [default: lz4]
  • --output, -o: Output pattern (use {input}, {timestamp}, {compression})
  • --workers, -w: Number of parallel workers
  • --validate: Validate compressed files after compression
  • --dry-run: Preview without compressing

Inspect Command

Inspect bag file contents and display comprehensive analysis:

# Inspect a bag file
rose inspect demo.bag

# Filter specific topics
rose inspect demo.bag --topics gps imu

# Show field analysis for messages
rose inspect demo.bag --show-fields

# Sort topics by different criteria
rose inspect demo.bag --sort frequency --reverse

# Save inspection results to file
rose inspect demo.bag -o report.txt

# Force reload or load if missing
rose inspect demo.bag --load
rose inspect demo.bag --load --force

Options:

  • --topics, -t: Filter specific topics
  • --show-fields: Show field analysis for messages
  • --sort: Sort topics by (name, count, frequency, size) [default: size]
  • --reverse: Reverse sort order
  • --output, -o: Save output to file
  • --load: Load bag if not cached (quick mode)

  • --force: Force reload even if cached

List Command (Cache Management)

List and manage cached bag metadata:

# Show all cached bags
rose list

# Show detailed content
rose list --content

# Remove a specific bag from cache
rose list remove demo.bag

# Clear all cache
rose list clear

Compression Support

Rose supports compression of bag files to significantly reduce file sizes. This is especially useful for storing and transferring large bag files.

Available Compression Types

Type Description Compression Ratio Speed Use Case
none No compression 0% Fastest When processing speed is critical
bz2 BZ2 compression ~80-90% Slower Best for long-term storage
lz4 LZ4 compression ~60-70% Faster Good balance of speed and compression

Configuration

Rose uses a unified configuration system with automatic validation. Configuration is loaded from rose.config.yaml in your project directory.

Quick Start:

# Copy example configuration
cp rose.config.yaml.example rose.config.yaml

# Edit configuration
nano rose.config.yaml

Example Configuration:

# Performance Settings
parallel_workers: 4
memory_limit_mb: 512

# Feature Toggles
enable_cache: true

# Default Behavior
compression_default: none
verbose_default: false
build_index_default: false

# Logging Settings
log_level: INFO
log_to_file: true

# UI Settings
theme_file: rose.theme.default.yaml
enable_colors: true

# Directory Settings
output_directory: output

Theme System

Rose uses a simple YAML-based theme system to customize UI colors. By default, Rose uses an orange cassette futurism theme inspired by 1980s computing.

Creating a Custom Theme

  1. Copy the default theme file:

    cp rose.theme.default.yaml rose.theme.custom.yaml

  2. Edit the colors in rose.theme.custom.yaml.

  3. Update rose.config.yaml to use your theme:

    theme_file: rose.theme.custom.yaml
