Reverse Call Tree (who calls this, N-deep)
Builds the tree of callers of a chosen symbol, transitively, to a chosen depth.
Read this before changing a routine and you want to know how far the change could ripple back through its callers: it builds the tree of callers to the depth you choose, or the callees with --direction callees.
How to run it
Full flag list: reverse-calltree in the CLI reference.

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