Reverse Call Tree who calls this N deep

Reverse Call Tree (who calls this, N-deep)

Builds the tree of callers of a chosen symbol, transitively, to a chosen depth. Reach for it to see how far a change to one routine could ripple backward through its callers.

Running it from the CLI

drag-lint reverse-calltree --qname <X> [--direction callers|callees] [--depth N] [--format text|json|dot|mermaid] [--json] --db PATH [--db ...]

Default direction is callers (who calls X); --direction callees instead shows what X calls. --depth bounds the tree; --format selects text, json, dot, or mermaid output. The command is cycle-guarded.

Reaching it in the IDE

drag-lint > Uses & Dependencies > Reverse Call Tree (who calls this, N-deep)...

What it needs

An index IS required -- reverse-calltree reads 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 --depth 2

This would show, up to 2 levels deep, who calls the Total member of TCustomerOrder.
