CalcTool

Utility toolkit — run, check, convert, analyze, generate, preview, batch, compare, and manage data entries. Each command logs input with timestamps for full traceability and review.

Commands

> Note: The export and status commands in the case dispatch also have utility variants (_export and _status) that provide structured export (json/csv/txt) and health check output respectively. However, the primary case match routes to the logging version.

Data Storage

All data is stored locally in ~/.local/share/calctool/. Each command writes to its own .log file (e.g., run.log, check.log, analyze.log). A unified history.log records every action with timestamps. No external services or databases required.

Log format: YYYY-MM-DD HH:MM|

Export formats: JSON, CSV, or plain text (via the _export helper function).

Requirements

• bash (version 4+ recommended)
• Standard POSIX utilities: date, wc, du, grep, tail, head, cat
• No external dependencies, no network access needed
• Works on Linux, macOS, and WSL

When to Use

1. Logging calculation results — Record computations, conversions, or analysis results with run, convert, or analyze for future reference
2. Batch processing and comparison — Log batch operations with batch and side-by-side comparisons with compare
3. Generating and previewing outputs — Use generate to log generated results and preview to log draft outputs before finalizing
4. Configuration and status tracking — Record configuration changes with config and system states with status for audit trails
5. Reporting and data export — Create report entries for periodic summaries and use stats or search to review all logged data

Examples

# Log a calculation run
calctool run "2 * (3 + 4) / 5 = 2.8"

# Log a unit conversion
calctool convert "100 USD to CNY = 725.30"

# Log an analysis result
calctool analyze "Dataset A: mean=45.2, std=12.1, n=500"

# Compare two results
calctool compare "Plan A: $12,000/yr vs Plan B: $10,800/yr — B saves 10%"

# Generate a report entry
calctool report "Q1 2026 summary: 142 entries, 98% accuracy"

# Search for specific entries
calctool search "USD"

# View summary statistics
calctool stats

# View recent activity
calctool recent

# Check health status
calctool status

How It Works

CalcTool stores all data locally in ~/.local/share/calctool/. Each command logs activity with timestamps for full traceability. Use stats to see a summary of entries per category with total counts and data size. Use search to find specific entries across all logs, recent to view the latest activity, or the built-in export helper to back up your data in JSON, CSV, or plain text format.
