Call Graph (Butterfly)

Since: 0.96.0-alpha

Shows callers and callees of one symbol together in a single "butterfly" view.

Read this when you want to see who calls a symbol and what it calls together, in one butterfly view, from the IDE menu. The same chart is available from the CLI with the butterfly verb.

How to run it

Full flag list: reverse-calltree in the CLI reference.

`--depth`	`N`
`--format`
`--json`
`--db`	`PATH`

Needs: index

Details

Shows callers and callees of one symbol together in a single "butterfly" view. Reach for it to see both directions of a symbol's call graph at once.

Running it from the CLI

There are two ways to get this chart, and they are genuinely different -- this is a deliberate asymmetry, not a duplicate.

The butterfly verb composes both wings in ONE command:

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

The IDE menu item does NOT call butterfly. It runs reverse-calltree TWICE -- once for callers, once with --direction callees -- and composes the two JSON documents itself into the dock's Call Graph tab:

drag-lint reverse-calltree --qname <X> --db <db> --depth 3 --format json
drag-lint reverse-calltree --qname <X> --db <db> --depth 3 --format json --direction callees

So butterfly is CLI-only: no IDE action invokes it. If you want the chart from a script, butterfly is the single-command option.

Reaching it in the IDE

drag-lint > Uses & Dependencies > Call Graph (Butterfly)...

What it needs

An index IS required -- both butterfly and the two reverse-calltree calls the IDE composes it from read the project's index database. The project's DB lives at <project folder>\_D-RAG\<project file>.sqlite; run drag-lint resolve-dbs --project <X.dproj> if you are unsure which one.

Example

Illustrative only:

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

This would produce a DOT-format graph touching the Total member of TCustomerOrder.
