* feat: add JSON output tests and README docs for analyze and status
Add 7 BATS tests covering `--json` output for `mo analyze` and `mo status`:
- schema structure
- field types
- pipe auto-detection.
Also document the `--json` flag in a new "Machine-Readable Output" README section, including the auto-detection behavior when piped.
* chore: use waitgroup go in status collector

Network rate calculation requires two samples to compute the delta.
In JSON mode, the collector was only called once, causing the network
field to always return nil.
This change adds a second collection call with a 1-second interval,
allowing the network rates to be calculated properly.
Add --json command-line flag to mo status that outputs system metrics
in JSON format without requiring a TTY environment.
This enables:
- Integration with GUI applications (e.g., native macOS apps)
- Use in automation scripts and monitoring systems
- Piping output to tools like jq for data extraction
- Recording metrics for analysis
Implementation:
- Add JSON struct tags to all metric types
- Add --json flag using Go's flag package
- Implement runJSONMode() for one-time metric collection
- Refactor main() to support both TUI and JSON modes
- Maintain 100% backward compatibility (default TUI unchanged)
Testing:
- All 454 existing tests pass
- JSON output validated with jq and python json.tool
- Pipeline and redirection work correctly
- No breaking changes to existing functionality
- renderHeader now returns empty string as second return value when
error message is present, avoiding duplicate mole in main.go View
- Add unit tests to prevent regression
Fixes P2 issue: view.go (line 184) + main.go (line 160)
When multiple disks are connected, the status command was sorting
only by size, causing external disks to appear first when they are
larger than the internal disk. This resulted in showing incorrect
free space (external disk size) instead of the internal disk.
The sort now prioritizes internal disks before sorting by size,
ensuring the internal disk always appears first.
Fixes#466
When the terminal is stretched wide, the header info line may wrap to
multiple lines but the mole position was calculated independently based
on terminal width, causing vertical misalignment.
Separate header and mole rendering so mole always appears on dedicated
lines below the header regardless of terminal width.
Add unit tests for parsing functions in `cmd/status/view_test.go`:
- `parseInt`: parses integers from strings with padding/decimals
- `parseRefreshRate`: parses display refresh rates from system output
- `isNoiseInterface`: filters noise network interfaces
- `parsePMSet`: parses macOS pmset battery output
Coverage for `cmd/status` improved from 8.4% to 12.6%.
- Add get_timestamp() helper and optimize log rotation
- Create mo log viewer with search/filter capabilities
- Improve test coverage to 18.4% with better assertions
- Add security fixes for grep injection prevention
Add unit tests for additional utility functions in `cmd/status/view_test.go`:
- `humanBytes`: byte formatting with decimals and units
- `humanBytesCompact`: compact byte formatting
- `splitDisks`: separates internal/external disks
- `diskLabel`: generates numbered disk labels
Coverage for cmd/status improved from 6.9% to 8.4%.
Add unit tests for utility functions in cmd/status/view_test.go:
- formatRate: MB/s rate formatting with adaptive precision
- shorten: string truncation with ellipsis
- humanBytesShort: byte formatting with binary units
Add unit tests for heap implementations in cmd/analyze/heap_test.go:
- entryHeap: min-heap for dirEntry (basic ops, empty, single element)
- largeFileHeap: min-heap for fileEntry (basic ops, top N pattern)
- Replace parentheses with commas for supplementary info
- Use commas instead of em-dashes for separators
- Update bullet points from - to * in some contexts
- Improve version extraction regex with fallback logic
Add comprehensive test coverage for the RingBuffer circular buffer
data structure used in network history tracking.
Test cases:
- Constructor initialization (NewRingBuffer)
- Empty buffer returns nil slice
- Adding elements within capacity
- Exact capacity boundary
- Wrap-around behavior with chronological ordering
- Multiple wrap-arounds stress test
- Single-element buffer edge case
- Slice returns independent copy (not reference)
- Disable sensors data collection (CPU temp already shown in CPU card)
- Remove unused sensor-related functions (collectSensors, prettifyLabel, hasSensorData, renderSensorsCard)
- Remove unused gopsutil/sensors import
- Fix inline spinner disown call with explicit PID
- Update version from 1.22.0 to 1.22.1
- Update SECURITY_AUDIT.md to match new version and date
- Fix display of invalid large values like 18446744073709544W
- macOS ioreg returns negative values as uint64 (two's complement)
- Detect overflow pattern (value > 2^63) and convert to signed
- Validate reasonable power range (-200W to 200W) for battery
- Add range validation for SystemPower (0 to 1000W)
Root cause: During charging, battery power is negative but ioreg
formats it as unsigned uint64, causing overflow. This fix properly
converts these values back to signed integers.
- Restore performance test threshold to 200ms (from 500ms)
User caching is highly effective (~8ms for 100 calls)
- Add unit tests for colorizeTemp() covering thresholds and edge cases
