butterfly

butterfly

Composes a symbol's callers (upward wing) and callees (downward wing) into one combined chart in a single command. Reach for it when you want the full two-directional call graph of a symbol without running two separate queries.

Running it from the CLI

drag-lint butterfly --qname <X> [--depth N] [--format dot|mermaid|text|json] [--output F] --db PATH [--db ...]

--qname <X> is the symbol to center the chart on. --depth N bounds how far each wing walks. --format selects dot (the default), mermaid, text, or json. --output F writes the chart to a file instead of stdout. --db PATH may be repeated.

Reaching it in the IDE

No IDE surface -- this is a CLI-only feature. The IDE's "Call Graph (Butterfly)..." menu item does NOT call this verb: it runs reverse-calltree twice instead (once plain for callers, once with --direction callees) and composes the two results itself into the dock's Call Graph tab. See Call Graph (Butterfly) for that path.

What it needs

An index IS required. The project's DB lives at <project folder>\_D-RAG\<project file>.sqlite; run drag-lint resolve-dbs --project <X.dproj> if unsure.

Example

Illustrative only:

drag-lint butterfly --qname CustomerOrder.TCustomerOrder.Total --db C:\Projects\MyApp\_D-RAG\MyApp.sqlite --format dot

This would produce one DOT chart showing both who calls Total and what Total calls.
