# ChartMaker

A data toolkit for chart-related data logging and export. Record, transform, query, and export data entries — all from the command line, all stored locally.

Commands

| Command | What it does |

|---------|-------------|

| `chartmaker ingest <input>` | Log a new ingest entry (no args = show recent entries) |

| `chartmaker transform <input>` | Log a transform entry |

| `chartmaker query <input>` | Log a query entry |

| `chartmaker filter <input>` | Log a filter entry |

| `chartmaker aggregate <input>` | Log an aggregate entry |

| `chartmaker visualize <input>` | Log a visualize entry |

| `chartmaker export <input>` | Log an export entry (see also export with format below) |

| `chartmaker sample <input>` | Log a sample entry |

| `chartmaker schema <input>` | Log a schema entry |

| `chartmaker validate <input>` | Log a validate entry |

| `chartmaker pipeline <input>` | Log a pipeline entry |

| `chartmaker profile <input>` | Log a profile entry |

| `chartmaker stats` | Show summary statistics across all log files |

| `chartmaker export <fmt>` | Export all data to json, csv, or txt format |

| `chartmaker search <term>` | Search all entries for a term (case-insensitive) |

| `chartmaker recent` | Show the 20 most recent activity log entries |

| `chartmaker status` | Health check — version, entry count, disk usage |

| `chartmaker help` | Show usage and available commands |

| `chartmaker version` | Print version string |

Each logging command (ingest, transform, query, etc.) accepts free-form text. Called without arguments, it shows the 20 most recent entries for that category.

Data Storage

All data is stored locally in `~/.local/share/chartmaker/`. Each command category writes to its own `.log` file, and all actions are recorded in `history.log` with timestamps.

Requirements

When to Use

# Export everything to CSV
