Implement comprehensive time tracking system with nytid track command using flat label tags

[Copilot]

Implementation of track Command - Enhanced Stats and Comprehensive Testing ✅

Implemented enhancements requested by @dbosk in comment #3332867808.

Stats Command Enhancement ✅

Co-occurring Label Breakdown: When filtering stats by specific labels, the command now shows a breakdown of other labels that appeared alongside the filter labels.

Example Use Case:

# Track work on different projects
nytid track start devel nytid      # 2 hours
nytid track start devel canvaslms  # 1.5 hours  
nytid track start devel nytid testing  # 1 hour

# Get stats for development work
nytid track stats devel

Output Shows:

• Total time for devel: 4.5 hours (sum of all entries with 'devel' label)
• Co-occurring label breakdown:
  • nytid: 3h (2h + 1h = time when nytid appeared with devel)
  • canvaslms: 1.5h (time when canvaslms appeared with devel)
  • testing: 1h (time when testing appeared with devel)

This shows how development time was distributed across different projects, answering questions like "How much of my development time was spent on nytid vs canvaslms?"

Implementation Details

Stats Command Logic:

• When filter labels are provided: Shows co-occurring labels (excludes the filter labels themselves from breakdown)
• When no filter: Shows all label totals (original behavior)
• Calculates percentages relative to the filtered total time
• Sorts by time spent (most time first)

Benefits:

• Project Time Analysis: See how time is distributed within a category (e.g., which courses consume development time)
• Activity Breakdown: Understand what activities take up time within a label (e.g., lecture vs grading within a course)
• Work Pattern Insights: Identify which related activities consume the most time

Comprehensive Testing ✅

Added Two New Test Suites:

1. test_stats_co_occurring_labels(): Tests the new co-occurring label functionality

   • Creates entries with various label combinations
   • Verifies total time calculations for filtered labels
   • Confirms co-occurring labels are shown correctly
   • Validates percentages and time breakdowns

2. test_all_tracking_module_functions(): Comprehensive integration test covering all commands

   • start: Single label, multiple labels (batch), resume without arguments
   • stop: Specific labels, batch stopping, --all flag
   • status: Active tracking display, notes display, empty status
   • notes: Adding notes to active labels
   • add: Manual entries with --offset, --at, --duration, --description
   • export: JSON and CSV formats
   • stats: Various filtering options

Test Coverage:

• All CLI commands exercised
• Time specification options (--offset, --at)
• Batch behavior and resume functionality
• Label filtering and co-occurrence
• Export formats
• Edge cases (empty status, no data)

All Features Working ✅

Complete feature set with enhanced testing:

• ✅ Flat label system
• ✅ Batch stopping behavior
• ✅ Resume functionality
• ✅ Label autocompletion
• ✅ Smart run command integration
• ✅ Stats with co-occurring label breakdown (new)
• ✅ Comprehensive test coverage for entire tracking module (new)
• ✅ Enhanced time specification
• ✅ Notes for labels
• ✅ StorageRoot integration

Fixes #21.

Fixed in commit 6f47478. Removed the incorrectly committed generated files (.py and .tex files generated from .nw sources) and temporary test files. Updated .gitignore to prevent this issue in the future by adding specific patterns for:

• Generated .py files from .nw sources in src/ directories
• Generated .tex files from .nw sources
• Temporary test directories created by pytest

The track command functionality remains fully intact - all files are properly regenerated during the build process as intended by the literate programming workflow.

@copilot please change the following:

Implemented both requested improvements in commit 93af7b2:

Enhanced Documentation: Added comprehensive design rationale covering:

• Hierarchical label system design and how it mirrors natural academic workflows
• Stack-based session management with LIFO removal patterns
• Detailed class architecture explaining TrackingEntry and ActiveSession relationships
• State management philosophy (graceful degradation, error recovery, lazy initialization)
• Complete configuration system integration documentation

Configuration System Integration: Replaced hardcoded constants with nytid's config system:

• track.data_dir: Configurable data storage location
• track.weekly_limit & track.daily_limit: Configurable warning thresholds
• Automatic fallback to sensible defaults when not configured
• Updated help text with configuration examples
• All 16 tests updated and passing with new config integration

The stats command now shows: "Uses configured default limits for warnings unless overridden by command options. Default limits can be set using: nytid config track.weekly_limit -s 40.0"

@copilot move the tests closer to the functions that they should test. Same with the documentation. It should be close to the code that it describes, use more code chunks if necessary.

@copilot move the tests closer to the functions that they should test. Same with the documentation. It should be close to the code that it describes, use more code chunks if necessary.

Reorganized the entire track.nw file in commit 589c329 following nytid's literate programming best practices:

Tests moved closer to functions: Each function's tests now immediately follow its implementation (e.g., TrackingEntry class → test_tracking_entry_* functions → ActiveSession class → test_active_session_* functions)

Documentation closer to code: Each function/command section starts with detailed documentation explaining the rationale, followed immediately by the implementation and then tests

Smaller, focused chunks: Broke large sections into smaller noweb chunks organized by functionality (e.g., <<tracking entry class>>, <<test tracking entry>>, <<active session class>>, <<test active session>>)

Structure now follows: Documentation → Implementation → Tests → Next Function, making it easy to understand each component's purpose, see how it's implemented, and verify it works correctly.

All 16 tests continue to pass with the reorganized structure.

@copilot: Please fix the following:

• The labels shouldn't be hierarchical, they should be flat. More like tags.
• We should be able to stop tracking any arbitrary label, not just the last one
  we started tracking.
• We shouldn't be able to have the same label tracking "twice in parallel".
  Starting the same label again should merge with the existing tracking, if
  possible.
• We should be able to add notes to any label, not just when using the add
  command.
• Revise the sectioning structure in the documentation. Now the code overview
  (<<track.py>>) appears in the Multi-format Export Capability section.
• To manage the data, use the StorageRoot system instead of get_tracking_dir
  and get_tracking_data_file. Or at least make those functions wrap around
  the StorageRoot.

[dbosk]

@copilot two more things.

First, when we use the run command, make the command the label and add the full command with arguments as a description.

Second, let the stats command take labels as arguments and do stats on just them.

[Copilot]

@copilot please make the following changes:

If we run nytid track start DD1310; nytid track lecture prep followed by nytid track stop, then that command should stop lecture and prep, but not DD1...

Implemented all three requested features in commit 05dd3cc:

1. Batch stopping: Labels started together now stop together. nytid track start DD1310; nytid track start lecture prep followed by nytid track stop stops lecture and prep (batch 2) but not DD1310 (batch 1).

2. Resume functionality: nytid track start without labels now resumes the most recently stopped labels. Works perfectly for the interruption scenario: nytid track run -l mail -- mutt → interrupted → nytid track stop → later → nytid track start resumes mail tracking.

3. Autocompletion: Added shell completion for both commands:

• stop: Completes with currently active labels only
• start: Completes with all previously used labels from history plus active ones

The system tracks which labels were started together using batch IDs and remembers the last stopped labels in the session state. All data persists across restarts.

@copilot two more things.

First, when we use the run command, make the command the label and add the full command with arguments as a description....

Implemented both features in commit 7c7e5ca:

Run command enhancement: The command name is now automatically used as a label, and the full command with arguments is stored as a description. For example, nytid track run mutt -f inbox tracks with label "mutt" and description "mutt -f inbox". Additional labels can still be added with --label.

Stats label filtering: The stats command now accepts labels as positional arguments to filter statistics. For example:

• nytid track stats DD1310 - shows only DD1310 time
• nytid track stats lecture grading - shows time for lecture or grading activities

The implementation includes comprehensive tests for both features.

Please fix it.

[Copilot]

@copilot, now the status command is broken:

Fixed in commit 78d5c48. The issue was that get_label_info() returns a 3-tuple (start_time, notes, batch_id) but the status command was unpacking it as a 2-tuple. Updated line 1305 to correctly unpack all three values:

start_time, notes, batch_id = info

The status command now works correctly.

Added comprehensive status command tests in commit 513b9c7 (bug fix) and this commit. The test suite now includes 6 tests positioned immediately after the status command implementation:

• test_status_no_tracking() - Empty session handling
• test_status_with_single_label() - Single label display
• test_status_with_multiple_labels() - Multiple labels
• test_status_with_notes() - Notes/description display
• test_status_tuple_unpacking_regression() - Critical regression test that explicitly verifies get_label_info() returns a 3-tuple and status command unpacks it correctly
• test_status_with_batch_tracking() - Batch behavior

The critical regression test documents exactly what bug it prevents and validates both the internal data structure and command execution, ensuring the ValueError won't happen again.

[dbosk]

@copilot: Please also ensure that everything in the tracking module is properly
tested.

The stats command was improved. However, please change so that the stats
command outputs stats for labels that have appeared along with the given
labels. So the given labels form the total time and the output shows how much
time was spent with each of the other labels that appeared along with the given
labels. For instance, given nytid track stats devel I want to see how much
time I spent in total on devel. But I also want to see how much of that total
development time was spent on nytid and how much was spent on
canvaslms---which will have been tracked as nytid track start devel canvaslms and nytid track start devel nytid.

[Copilot]

@copilot: Please also ensure that everything in the tracking module is properly
tested.
...

Implemented both requested changes in commit a375849:

Stats co-occurring label breakdown: When filtering by labels (e.g., nytid track stats devel), the command now shows which other labels appeared alongside the filter labels and how much time was spent with each. For example:

• Filter by devel shows total development time
• Breakdown shows nytid: 3h, canvaslms: 1.5h (labels that co-occurred with devel)
• Percentages calculated relative to the filtered total

Comprehensive testing: Added two new test suites:

• test_stats_co_occurring_labels(): Validates the co-occurring label functionality with various label combinations
• test_all_tracking_module_functions(): Integration test exercising all tracking commands (start, stop, status, notes, add, export, stats) with various options and edge cases

The stats command now answers questions like "How much of my development time was spent on nytid vs canvaslms?" by showing the breakdown of co-occurring labels.

[dbosk]

Improved in #243.
