Update this file whenever priorities change or major decisions are made. Reference companion documents for details: [product.md](.kilicode/rules/memory-bank/product.md), [architecture.md](.kilicode/rules/memory-bank/architecture.md), [tech.md](.kilicode/rules/memory-bank/tech.md), [tasks.md](.kilicode/rules/memory-bank/tasks.md). ## 1. Project Scope Describe what Garmin Analyser will deliver in concrete terms. Keep this section short and authoritative. - Scope summary: TODO - Operating modes to support: File, Directory, Garmin Connect, TUI - Architectural path: Modular pipeline is primary; legacy retained until TUI migrates - Supported formats: FIT now; TCX/GPX planned ## 2. Core Goals List the top goals that define success. - Accurate parsing into [models/workout.py](models/workout.py) - Robust analysis via [analyzers/workout_analyzer.py](analyzers/workout_analyzer.py) - Clear charts and reports via [visualizers/chart_generator.py](visualizers/chart_generator.py) and [visualizers/report_generator.py](visualizers/report_generator.py) - Offline-friendly, configurable, with clean CLI and optional TUI ## 3. Non-Goals Clarify what is explicitly out of scope. - Real-time recording or live dashboards - Training plan generation - Cloud-hosted services ## 4. Stakeholders and Users - Primary: Cyclists and coaches needing offline analysis - Secondary: Developers integrating modular components ## 5. Interfaces and Entry Points Core interfaces to run the system. Keep these consistent and documented. - CLI orchestrator: [main.py](main.py) - Alt CLI: [cli.py](cli.py) - Legacy TUI: [garmin_cycling_analyzer_tui.py](garmin_cycling_analyzer_tui.py) ## 6. Architecture Alignment Align decisions with the architecture document. - Modular pipeline: clients → parsers → analyzers → visualizers/reporting - Legacy monolith retained for TUI until migration is complete See: [architecture.md](.kilicode/rules/memory-bank/architecture.md) ## 7. Tech and Dependencies Keep tech constraints explicit and current. - Python 3.9+, pandas, numpy - fitparse for FIT; WeasyPrint for PDF; garminconnect for auth - Plotly for dashboard; matplotlib/seaborn in legacy See: [tech.md](.kilicode/rules/memory-bank/tech.md) ## 8. Data Sources and Formats - Local files: FIT supported - Garmin Connect: via [clients/garmin_client.py](clients/garmin_client.py) - Planned: TCX, GPX ## 9. Outputs and UX Goals - Charts: PNG and HTML dashboard - Reports: HTML, PDF, Markdown - UX: minimal setup, clean outputs, clear status in CLI/TUI ## 10. Constraints and Assumptions - Assumes 1 Hz sampling unless specified otherwise - Default zones and thresholds configurable via [config/config.yaml](config/config.yaml) and [config/settings.py](config/settings.py) - WeasyPrint may require system libraries ## 11. Risks and Decisions Track decisions and risks that impact scope. - Credentials naming: standardize on GARMIN_EMAIL and GARMIN_PASSWORD; fall back from GARMIN_USERNAME in legacy - Analyzer outputs vs templates: normalize naming; add speed_analysis - CLI namespace: fix [cli.py](cli.py) imports or adjust packaging - Summary report template: add or remove reference in [visualizers/report_generator.py](visualizers/report_generator.py) ## 12. Roadmap (Phases) Phase 1: Consolidation - Unify credential env vars across stacks - Align analyzer outputs with templates; add speed_analysis - Update ChartGenerator to derive avg/max - Resolve summary report template reference - Validate packaging and imports Phase 2: Testing and Quality - Unit tests: parsers and analyzers - Integration test: parse → analyze → render via [main.py](main.py) - Template rendering tests: [visualizers/report_generator.py](visualizers/report_generator.py) Phase 3: TUI Migration - Introduce services layer and route TUI to modular components - Remove legacy analyzer once parity is reached ## 13. Acceptance Criteria Define objective criteria to declare success. - CLI and TUI authenticate using unified env vars - Reports render without missing variables; charts show correct annotations - Packaging ships templates; CLI imports resolve in editable and wheel installs - Tests pass locally and in CI ## 14. Ownership and Update Process - Owner: Developer responsible for Garmin Analyser consolidation - Update cadence: on major changes or after significant merges - When updating, also review [tasks.md](.kilicode/rules/memory-bank/tasks.md) and [context.md](.kilicode/rules/memory-bank/context.md) ## 15. Change Log Keep a short history of major brief updates. - 2025-10-05: Initial brief template created ## 16. Fill-in Checklist (to be completed by owner) - [ ] Scope summary written - [ ] Goals validated with stakeholders - [ ] Non-goals confirmed - [ ] Risks and decisions documented - [ ] Roadmap phased plan agreed - [ ] Acceptance criteria reviewed ``` # .pytest_cache/.gitignore ``` # Created by pytest automatically. * ``` # .pytest_cache/CACHEDIR.TAG ```TAG Signature: 8a477f597d28d172789f06886806bc55 # This file is a cache directory tag created by pytest. # For information about cache directory tags, see: # https://bford.info/cachedir/spec.html ``` # .pytest_cache/README.md ```md # pytest cache directory # This directory contains data from the pytest's cache plugin, which provides the `--lf` and `--ff` options, as well as the `cache` fixture. **Do not** commit this to version control.

Garmin Analyser A comprehensive Python application for analyzing Garmin workout data from FIT, TCX, and GPX files, as well as direct integration with Garmin Connect. Provides detailed power, heart rate, and performance analysis with beautiful visualizations and comprehensive reports. ## Features - **Multi-format Support**: Parse FIT files. TCX and GPX parsing is not yet implemented and is planned for a future enhancement. - **Garmin Connect Integration**: Direct download from Garmin Connect - **Comprehensive Analysis**: Power, heart rate, speed, elevation, and zone analysis - **Advanced Metrics**: Normalized Power, Intensity Factor, Training Stress Score - **Interactive Charts**: Power curves, heart rate zones, elevation profiles - **Detailed Reports**: HTML, PDF, and Markdown reports with customizable templates - **Interval Detection**: Automatic detection and analysis of workout intervals - **Performance Tracking**: Long-term performance trends and summaries ## Installation ### Requirements - Python 3.8 or higher - pip package manager ### Install Dependencies \`\`\`bash pip install -r requirements.txt \`\`\` ### Optional Dependencies For PDF report generation: \`\`\`bash pip install weasyprint \`\`\` ## Quick Start ### Basic Usage Analyze a single workout file: \`\`\`bash python main.py --file path/to/workout.fit --report --charts \`\`\` Analyze all workouts in a directory: \`\`\`bash python main.py --directory path/to/workouts --summary --format html \`\`\` Download from Garmin Connect: \`\`\`bash python main.py --garmin-connect --report --charts --summary \`\`\` ### Command Line Options \`\`\` usage: main.py [-h] [--config CONFIG] [--verbose] (--file FILE | --directory DIRECTORY | --garmin-connect | --workout-id WORKOUT_ID | --download-all | --reanalyze-all) [--ftp FTP] [--max-hr MAX_HR] [--zones ZONES] [--cog COG] [--output-dir OUTPUT_DIR] [--format {html,pdf,markdown}] [--charts] [--report] [--summary] Analyze Garmin workout data from files or Garmin Connect options: -h, --help show this help message and exit --config CONFIG, -c CONFIG Configuration file path --verbose, -v Enable verbose logging Input options: --file FILE, -f FILE Path to workout file (FIT, TCX, or GPX) --directory DIRECTORY, -d DIRECTORY Directory containing workout files --garmin-connect Download from Garmin Connect --workout-id WORKOUT_ID Analyze specific workout by ID from Garmin Connect --download-all Download all cycling activities from Garmin Connect (no analysis) --reanalyze-all Re-analyze all downloaded activities and generate reports Analysis options: --ftp FTP Functional Threshold Power (W) --max-hr MAX_HR Maximum heart rate (bpm) --zones ZONES Path to zones configuration file --cog COG Cog size (teeth) for power calculations. Auto-detected if not provided Output options: --output-dir OUTPUT_DIR Output directory for reports and charts --format {html,pdf,markdown} Report format --charts Generate charts --report Generate comprehensive report --summary Generate summary report for multiple workouts Examples: Analyze latest workout from Garmin Connect: python main.py --garmin-connect Analyze specific workout by ID: python main.py --workout-id 123456789 Download all cycling workouts: python main.py --download-all Re-analyze all downloaded workouts: python main.py --reanalyze-all Analyze local FIT file: python main.py --file path/to/workout.fit Analyze directory of workouts: python main.py --directory data/ Configuration: Set Garmin credentials in .env file: GARMIN_EMAIL and GARMIN_PASSWORD Configure zones in config/config.yaml or use --zones flag Override FTP with --ftp flag, max HR with --max-hr flag Output: Reports saved to output/ directory by default Charts saved to output/charts/ when --charts is used \`\`\` ## Setup credentials Canonical environment variables: - GARMIN_EMAIL - GARMIN_PASSWORD Single source of truth: - Credentials are centrally accessed via [get_garmin_credentials()](config/settings.py:31). If GARMIN_EMAIL is not set but GARMIN_USERNAME is present, the username value is used as email and a one-time deprecation warning is logged. GARMIN_USERNAME is deprecated and will be removed in a future version. Linux/macOS (bash/zsh): \`\`\`bash export GARMIN_EMAIL="you@example.com" export GARMIN_PASSWORD="your-app-password" \`\`\` Windows PowerShell: \`\`\`powershell $env:GARMIN_EMAIL = "you@example.com" $env:GARMIN_PASSWORD = "your-app-password" \`\`\` .env sample: \`\`\`dotenv GARMIN_EMAIL=you@example.com GARMIN_PASSWORD=your-app-password \`\`\` Note on app passwords: - If your Garmin account uses two-factor authentication or app-specific passwords, create an app password in your Garmin account settings and use it for GARMIN_PASSWORD. TUI with dotenv: - When using the TUI with dotenv, prefer GARMIN_EMAIL and GARMIN_PASSWORD in your .env file. GARMIN_USERNAME continues to work via fallback with a one-time deprecation warning, but it is deprecated; switch to GARMIN_EMAIL. Parity and unaffected behavior: - Authentication and download parity is maintained. Original ZIP downloads and FIT extraction workflows are unchanged in [clients/garmin_client.py](clients/garmin_client.py). - Alternate format downloads (FIT, TCX, GPX) are unaffected by this credentials change. ## Configuration ### Basic Configuration Create a `config/config.yaml` file: \`\`\`yaml # Garmin Connect credentials # Credentials are provided via environment variables (GARMIN_EMAIL, GARMIN_PASSWORD). # Do not store credentials in config.yaml. See "Setup credentials" in README. # Output settings output_dir: output log_level: INFO # Training zones zones: ftp: 250 # Functional Threshold Power (W) max_heart_rate: 185 # Maximum heart rate (bpm) power_zones: - name: Active Recovery min: 0 max: 55 percentage: true - name: Endurance min: 56 max: 75 percentage: true - name: Tempo min: 76 max: 90 percentage: true - name: Threshold min: 91 max: 105 percentage: true - name: VO2 Max min: 106 max: 120 percentage: true - name: Anaerobic min: 121 max: 150 percentage: true heart_rate_zones: - name: Zone 1 min: 0 max: 60 percentage: true - name: Zone 2 min: 60 max: 70 percentage: true - name: Zone 3 min: 70 max: 80 percentage: true - name: Zone 4 min: 80 max: 90 percentage: true - name: Zone 5 min: 90 max: 100 percentage: true \`\`\` ### Advanced Configuration You can also specify zones configuration in a separate file: \`\`\`yaml # zones.yaml ftp: 275 max_heart_rate: 190 power_zones: - name: Recovery min: 0 max: 50 percentage: true - name: Endurance min: 51 max: 70 percentage: true # ... additional zones \`\`\` ## Usage Examples ### Single Workout Analysis \`\`\`bash # Analyze a single FIT file with custom FTP python main.py --file workouts/2024-01-15-ride.fit --ftp 275 --report --charts # Generate PDF report python main.py --file workouts/workout.tcx --format pdf --report # Quick analysis with verbose output python main.py --file workout.gpx --verbose --report \`\`\` ### Batch Analysis \`\`\`bash # Analyze all files in a directory python main.py --directory data/workouts/ --summary --charts --format html # Analyze with custom zones python main.py --directory data/workouts/ --zones config/zones.yaml --summary \`\`\` ### Reports: normalized variables example Reports consume normalized speed and heart rate keys in templates. Example (HTML template): \`\`\`jinja2 {# See workout_report.html #}

Sport: {{ metadata.sport }} ({{ metadata.sub_sport }})

Speed: {{ summary.avg_speed_kmh|default(0) }} km/h; HR: {{ summary.avg_hr|default(0) }} bpm

See [WorkoutAnalyzer.analyze_workout()](analyzers/workout_analyzer.py:1) and [ReportGenerator._prepare_report_data()](visualizers/report_generator.py:1) for implementation details. - Summary keys: - summary.avg_speed_kmh — Average speed in km/h (derived from speed_mps) - summary.avg_hr — Average heart rate in beats per minute (bpm) - Speed analysis keys: - speed_analysis.avg_speed_kmh — Average speed in km/h - speed_analysis.max_speed_kmh — Maximum speed in km/h - Heart rate analysis keys: - heart_rate_analysis.avg_hr — Average heart rate (bpm) - heart_rate_analysis.max_hr — Maximum heart rate (bpm) - Backward-compatibility aliases maintained in code: - summary.avg_speed — Alias of avg_speed_kmh - summary.avg_heart_rate — Alias of avg_hr Guidance: templates should use the normalized names going forward. ## Templates: variables and metadata Templates should reference normalized variables and the workout metadata fields: - Use metadata.sport and metadata.sub_sport instead of activity_type. - Example snippet referencing normalized keys: - speed: {{ summary.avg_speed_kmh }} km/h; HR: {{ summary.avg_hr }} bpm - For defensive rendering, Jinja defaults may be used (e.g., {{ summary.avg_speed_kmh|default(0) }}), though normalized keys are expected to be present. Reference templates: - [workout_report.html](visualizers/templates/workout_report.html:1) - [workout_report.md](visualizers/templates/workout_report.md:1) ## Migration note - Legacy template fields avg_speed and avg_heart_rate are deprecated; the code provides aliases (summary.avg_speed → avg_speed_kmh, summary.avg_heart_rate → avg_hr) to prevent breakage temporarily. - Users should update custom templates to use avg_speed_kmh and avg_hr. - metadata.activity_type is replaced by metadata.sport and metadata.sub_sport. ## Customization ### Custom Report Templates You can customize report templates by modifying the files in `visualizers/templates/`: - `workout_report.html`: HTML report template - `workout_report.md`: Markdown report template - `summary_report.html`: Summary report template ### Adding New Analysis Metrics Extend the `WorkoutAnalyzer` class in `analyzers/workout_analyzer.py`: \`\`\`python def analyze_custom_metric(self, workout: WorkoutData) -> dict: """Analyze custom metric.""" # Your custom analysis logic here return {'custom_metric': value} \`\`\` ### Custom Chart Types Add new chart types in `visualizers/chart_generator.py`: \`\`\`python def generate_custom_chart(self, workout: WorkoutData, analysis: dict) -> str: """Generate custom chart.""" # Your custom chart logic here return chart_path \`\`\` ## Troubleshooting ### Common Issues **File Not Found Errors** - Ensure file paths are correct and files exist - Check file permissions **Garmin Connect Authentication** - Verify GARMIN_EMAIL and GARMIN_PASSWORD environment variables (or entries in your .env) are set; fallback from GARMIN_USERNAME logs a one-time deprecation warning via [get_garmin_credentials()](config/settings.py:31) - Check internet connection - Ensure Garmin Connect account is active **Missing Dependencies** - Run `pip install -r requirements.txt` - For PDF support: `pip install weasyprint` **Performance Issues** - For large datasets, use batch processing - Consider using `--summary` flag for multiple files ### Debug Mode Enable verbose logging for troubleshooting: \`\`\`bash python main.py --verbose --file workout.fit --report \`\`\` ## API Reference ### Core Classes - `WorkoutData`: Main workout data structure - `WorkoutAnalyzer`: Performs workout analysis - `ChartGenerator`: Creates visualizations - `ReportGenerator`: Generates reports - `GarminClient`: Handles Garmin Connect integration ### Example API Usage \`\`\`python from pathlib import Path from config.settings import Settings from parsers.file_parser import FileParser from analyzers.workout_analyzer import WorkoutAnalyzer # Initialize components settings = Settings('config/config.yaml') parser = FileParser() analyzer = WorkoutAnalyzer(settings.zones) # Parse and analyze workout workout = parser.parse_file(Path('workout.fit')) analysis = analyzer.analyze_workout(workout) # Access results print(f"Average Power: {analysis['summary']['avg_power']} W") print(f"Training Stress Score: {analysis['summary']['training_stress_score']}") \`\`\` ## Contributing 1.

Provides detailed power, heart rate, and performance analysis with beautiful visualizations and comprehensive reports via a modular command-line interface. ## Features - **Multi-format Support**: Parse FIT files. TCX and GPX parsing is not yet implemented and is planned for a future enhancement. - **Garmin Connect Integration**: Direct download from Garmin Connect - **Comprehensive Analysis**: Power, heart rate, speed, elevation, and zone analysis - **Advanced Metrics**: Normalized Power, Intensity Factor, Training Stress Score - **Interactive Charts**: Power curves, heart rate zones, elevation profiles - **Detailed Reports**: HTML, PDF, and Markdown reports with customizable templates - **Interval Detection**: Automatic detection and analysis of workout intervals - **Performance Tracking**: Long-term performance trends and summaries ## Installation ### Requirements - Python 3.8 or higher - pip package manager ### Install Dependencies \`\`\`bash pip install -r requirements.txt \`\`\` ### Database Setup (New Feature) The application now uses SQLite with Alembic for database migrations to track downloaded activities. To initialize the database: \`\`\`bash # Run database migrations alembic upgrade head \`\`\` ### Optional Dependencies For PDF report generation: \`\`\`bash pip install weasyprint \`\`\` ## Quick Start ### Basic Usage The application uses a subcommand-based CLI structure. Here are some basic examples: Analyze a single workout file: \`\`\`bash python main.py analyze --file path/to/workout.fit --report --charts \`\`\` Analyze all workouts in a directory: \`\`\`bash python main.py batch --directory path/to/workouts --summary --format html \`\`\` Download and analyze latest workout from Garmin Connect: \`\`\`bash python main.py analyze --garmin-connect --report --charts \`\`\` Download all cycling activities from Garmin Connect: \`\`\`bash python main.py download --all --limit 100 --output-dir data/garmin_downloads \`\`\` Re-analyze previously downloaded workouts: \`\`\`bash python main.py reanalyze --input-dir data/garmin_downloads --output-dir reports/reanalysis --charts --report \`\`\` Force re-download of specific activity (bypasses database tracking): \`\`\`bash python main.py download --workout-id 123456789 --force \`\`\` Show current configuration: \`\`\`bash python main.py config --show \`\`\` ### Command Line Options For a full list of commands and options, run: \`\`\`bash python main.py --help python main.py [command] --help \`\`\` Example output for `python main.py --help`: \`\`\` usage: main.py [-h] [--verbose] {analyze,batch,download,reanalyze,config} ... Analyze Garmin workout data from files or Garmin Connect positional arguments: {analyze,batch,download,reanalyze,config} Available commands analyze Analyze a single workout or download from Garmin Connect batch Analyze multiple workout files in a directory download Download activities from Garmin Connect reanalyze Re-analyze all downloaded activities config Manage configuration options: -h, --help show this help message and exit --verbose, -v Enable verbose logging \`\`\` Example output for `python main.py analyze --help`: \`\`\` usage: main.py analyze [-h] [--file FILE] [--garmin-connect] [--workout-id WORKOUT_ID] [--ftp FTP] [--max-hr MAX_HR] [--zones ZONES] [--cog COG] [--output-dir OUTPUT_DIR] [--format {html,pdf,markdown}] [--charts] [--report] Analyze a single workout or download from Garmin Connect options: -h, --help show this help message and exit --file FILE, -f FILE Path to workout file (FIT, TCX, or GPX) --garmin-connect Download and analyze latest workout from Garmin Connect --workout-id WORKOUT_ID Analyze specific workout by ID from Garmin Connect --ftp FTP Functional Threshold Power (W) --max-hr MAX_HR Maximum heart rate (bpm) --zones ZONES Path to zones configuration file --cog COG Cog size (teeth) for power calculations. Auto-detected if not provided --output-dir OUTPUT_DIR Output directory for reports and charts --format {html,pdf,markdown} Report format --charts Generate charts --report Generate comprehensive report --force Force download even if activity already exists in database \`\`\` ### Configuration: Set Garmin credentials in `.env` file: `GARMIN_EMAIL` and `GARMIN_PASSWORD`. Configure zones in `config/config.yaml` or use `--zones` flag. Override FTP with `--ftp` flag, max HR with `--max-hr` flag. ### Output: Reports saved to `output/` directory by default. Charts saved to `output/charts/` when `--charts` is used. ## Deprecation Notice The Text User Interface (TUI) and legacy analyzer have been removed in favor of the more robust and maintainable modular command-line interface (CLI) implemented solely in `main.py`. The `cli.py` file has been removed. All functionality from the legacy components has been successfully migrated to the modular stack. ## Setup credentials Canonical environment variables: - GARMIN_EMAIL - GARMIN_PASSWORD Single source of truth: - Credentials are centrally accessed via [get_garmin_credentials()](config/settings.py:31). If GARMIN_EMAIL is not set but GARMIN_USERNAME is present, the username value is used as email and a one-time deprecation warning is logged. GARMIN_USERNAME is deprecated and will be removed in a future version. Linux/macOS (bash/zsh): \`\`\`bash export GARMIN_EMAIL="you@example.com" export GARMIN_PASSWORD="your-app-password" \`\`\` Windows PowerShell: \`\`\`powershell $env:GARMIN_EMAIL = "you@example.com" $env:GARMIN_PASSWORD = "your-app-password" \`\`\` .env sample: \`\`\`dotenv GARMIN_EMAIL=you@example.com GARMIN_PASSWORD=your-app-password \`\`\` Note on app passwords: - If your Garmin account uses two-factor authentication or app-specific passwords, create an app password in your Garmin account settings and use it for GARMIN_PASSWORD. Parity and unaffected behavior: - Authentication and download parity is maintained. Original ZIP downloads and FIT extraction workflows are unchanged in [clients/garmin_client.py](clients/garmin_client.py). - Alternate format downloads (FIT, TCX, GPX) are unaffected by this credentials change. ## Database Tracking The application now tracks downloaded activities in a SQLite database (`garmin_analyser.db`) to avoid redundant downloads and provide download history. ### Database Schema The database tracks: - Activity ID and metadata - Download status and timestamps - File checksums and sizes - Error information for failed downloads ### Database Location By default, the database is stored at: - `garmin_analyser.db` in the project root directory ### Migration Commands \`\`\`bash # Initialize database schema alembic upgrade head # Create new migration (for developers) alembic revision --autogenerate -m "description" # Check migration status alembic current # Downgrade database alembic downgrade -1 \`\`\` ## Configuration ### Basic Configuration Create a `config/config.yaml` file: \`\`\`yaml # Garmin Connect credentials # Credentials are provided via environment variables (GARMIN_EMAIL, GARMIN_PASSWORD). # Do not store credentials in config.yaml. See "Setup credentials" in README. # Output settings output_dir: output log_level: INFO # Training zones zones: ftp: 250 # Functional Threshold Power (W) max_heart_rate: 185 # Maximum heart rate (bpm) power_zones: - name: Active Recovery min: 0 max: 55 percentage: true - name: Endurance min: 56 max: 75 percentage: true - name: Tempo min: 76 max: 90 percentage: true - name: Threshold min: 91 max: 105 percentage: true - name: VO2 Max min: 106 max: 120 percentage: true - name: Anaerobic min: 121 max: 150 percentage: true heart_rate_zones: - name: Zone 1 min: 0 max: 60 percentage: true - name: Zone 2 min: 60 max: 70 percentage: true - name: Zone 3 min: 70 max: 80 percentage: true - name: Zone 4 min: 80 max: 90 percentage: true - name: Zone 5 min: 90 max: 100 percentage: true \`\`\` ### Advanced Configuration You can also specify zones configuration in a separate file: \`\`\`yaml # zones.yaml ftp: 275 max_heart_rate: 190 power_zones: - name: Recovery min: 0 max: 50 percentage: true - name: Endurance min: 51 max: 70 percentage: true # ... additional zones \`\`\` ## Usage Examples ### Single Workout Analysis \`\`\`bash # Analyze a single FIT file with custom FTP python main.py --file workouts/2024-01-15-ride.fit --ftp 275 --report --charts # Generate PDF report python main.py --file workouts/workout.tcx --format pdf --report # Quick analysis with verbose output python main.py --file workout.gpx --verbose --report \`\`\` ### Batch Analysis \`\`\`bash # Analyze all files in a directory python main.py --directory data/workouts/ --summary --charts --format html # Analyze with custom zones python main.py --directory data/workouts/ --zones config/zones.yaml --summary \`\`\` ### Reports: normalized variables example Reports consume normalized speed and heart rate keys in templates. Example (HTML template): \`\`\`jinja2 {# See workout_report.html #}

Sport: {{ metadata.sport }} ({{ metadata.sub_sport }})

Speed: {{ summary.avg_speed_kmh|default(0) }} km/h; HR: {{ summary.avg_hr|default(0) }} bpm

See [WorkoutAnalyzer.analyze_workout()](analyzers/workout_analyzer.py:1) and [ReportGenerator._prepare_report_data()](visualizers/report_generator.py:1) for implementation details. - Summary keys: - summary.avg_speed_kmh — Average speed in km/h (derived from speed_mps) - summary.avg_hr — Average heart rate in beats per minute (bpm) - Speed analysis keys: - speed_analysis.avg_speed_kmh — Average speed in km/h - speed_analysis.max_speed_kmh — Maximum speed in km/h - Heart rate analysis keys: - heart_rate_analysis.avg_hr — Average heart rate (bpm) - heart_rate_analysis.max_hr — Maximum heart rate (bpm) - Backward-compatibility aliases maintained in code: - summary.avg_speed — Alias of avg_speed_kmh - summary.avg_heart_rate — Alias of avg_hr Guidance: templates should use the normalized names going forward. ## Templates: variables and metadata Templates should reference normalized variables and the workout metadata fields: - Use metadata.sport and metadata.sub_sport instead of activity_type. - Example snippet referencing normalized keys: - speed: {{ summary.avg_speed_kmh }} km/h; HR: {{ summary.avg_hr }} bpm - For defensive rendering, Jinja defaults may be used (e.g., {{ summary.avg_speed_kmh|default(0) }}), though normalized keys are expected to be present. Reference templates: - [workout_report.html](visualizers/templates/workout_report.html:1) - [workout_report.md](visualizers/templates/workout_report.md:1) ## Migration note - Legacy template fields avg_speed and avg_heart_rate are deprecated; the code provides aliases (summary.avg_speed → avg_speed_kmh, summary.avg_heart_rate → avg_hr) to prevent breakage temporarily. - Users should update custom templates to use avg_speed_kmh and avg_hr. - metadata.activity_type is replaced by metadata.sport and metadata.sub_sport. ## Customization ### Custom Report Templates You can customize report templates by modifying the files in `visualizers/templates/`: - `workout_report.html`: HTML report template - `workout_report.md`: Markdown report template - `summary_report.html`: Summary report template ### Adding New Analysis Metrics Extend the `WorkoutAnalyzer` class in `analyzers/workout_analyzer.py`: \`\`\`python def analyze_custom_metric(self, workout: WorkoutData) -> dict: """Analyze custom metric.""" # Your custom analysis logic here return {'custom_metric': value} \`\`\` ### Custom Chart Types Add new chart types in `visualizers/chart_generator.py`: \`\`\`python def generate_custom_chart(self, workout: WorkoutData, analysis: dict) -> str: """Generate custom chart.""" # Your custom chart logic here return chart_path \`\`\` ## Troubleshooting ### Common Issues **File Not Found Errors** - Ensure file paths are correct and files exist - Check file permissions **Garmin Connect Authentication** - Verify GARMIN_EMAIL and GARMIN_PASSWORD environment variables (or entries in your .env) are set; fallback from GARMIN_USERNAME logs a one-time deprecation warning via [get_garmin_credentials()](config/settings.py:31) - Check internet connection - Ensure Garmin Connect account is active **Missing Dependencies** - Run `pip install -r requirements.txt` - For PDF support: `pip install weasyprint` **Performance Issues** - For large datasets, use batch processing - Consider using `--summary` flag for multiple files **Database Issues** - If database becomes corrupted, delete `garmin_analyser.db` and run `alembic upgrade head` - Check database integrity: `sqlite3 garmin_analyser.db "PRAGMA integrity_check;"` ### Debug Mode Enable verbose logging for troubleshooting: \`\`\`bash python main.py --verbose --file workout.fit --report \`\`\` ## API Reference ### Core Classes - `WorkoutData`: Main workout data structure - `WorkoutAnalyzer`: Performs workout analysis - `ChartGenerator`: Creates visualizations - `ReportGenerator`: Generates reports - `GarminClient`: Handles Garmin Connect integration ### Example API Usage \`\`\`python from pathlib import Path from config.settings import Settings from parsers.file_parser import FileParser from analyzers.workout_analyzer import WorkoutAnalyzer # Initialize components settings = Settings('config/config.yaml') parser = FileParser() analyzer = WorkoutAnalyzer(settings.zones) # Parse and analyze workout workout = parser.parse_file(Path('workout.fit')) analysis = analyzer.analyze_workout(workout) # Access results print(f"Average Power: {analysis['summary']['avg_power']} W") print(f"Training Stress Score: {analysis['summary']['training_stress_score']}") \`\`\` ## Contributing 1.
