Displays calls made to a specified function, showing the call graph inbound to the target function.
This query identifies all call sites that invoke a named function, producing an inbound call graph. Given a target function name, it reports each caller and call location, which is useful for understanding how a function is used across the codebase.
The query accepts function names via an external predicate (targetFunction).
This query is primarily used for:
- Finding all callers of a specific function
- Impact analysis before modifying a function signature
- Understanding usage patterns and entry points
The following Swift code demonstrates inbound calls to targetFunc:
func targetFunc() {} // Target function for analysis
func caller1() { targetFunc() }
func caller2() { targetFunc() }Running with targetFunction = "targetFunc" produces results showing each call site with the message pattern Call to `targetFunc` from `caller1.
The query is a @kind problem query producing rows of:
select call, "Call to `target` from `caller`"
