ask change impact
The blast radius of a change. One of the diagram questions of the ask verb -- see Diagrams and Charts for the model, the bundle and click-to-source.
Answered in-process by the engine (drag-lint ask); no PowerShell is needed (see Charts and the IDE).
From RAD Studio: drag-lint > Reports > What a change here would break... -- put the caret on the selection first (see IDE Menu Reference).
drag-lint ask --question change-impact --at <file.pas>:<line>:<col> --db <project.sqlite>
The selection is the symbol under --at (resolved exactly as Type at Cursor resolves a caret). From a terminal, ask it by name:
drag-lint ask change-impact --target DRagLint.Preprocess.Profile.ProfileFromDproj --db <project.sqlite>
A method, routine or type.
Everything that could break if the selection changes: its callers, their callers, and so on to the requested depth, grouped into SOURCE-DIRECTORY zones, each row tagged with the hop at which it was reached. For a TYPE the walk starts from every member.
The impact walk over CALLERS -- edges INTO a symbol are owned by the calling file, which is why this direction is reliable.
Depth (default 3); frontier cap 400 (reported when hit); rows per zone (default 8, "+N more" beyond).
An unresolved caller is invisible here, so a small radius is a FLOOR, not a ceiling. Pair it with who-calls, which adds the name-matched bucket.
Question change-impact, target DRagLint.Preprocess.Profile.ProfileFromDproj, drag-lint's self-index. Clickable SVG. The command that produced it is in the caption on Diagrams and Charts.
