Find Java local variable references

Recipe IDio.moderne.prethink.FindJavaLocalVariableReferences

Artifactio.moderne.recipe:rewrite-prethink

Report regular block-local declarations referenced by bare ordinary invocation argument, select or direct method-return identifiers, with original declaration and reference identities, source ranges and explicit binding states. Binding follows lexical visibility and declarator order in the same nearest ordinary method; reassignment retains declaration identity. Excludes fields, formals, lambda bodies, captures, constructors, initializers and assignment-target context. Does not change sources or establish initializer values, reaching definitions, taint or runtime flow.

Data tables

Java local variable references

io.moderne.prethink.table.JavaLocalVariableReferences

Regular block-local declarations referenced by bare ordinary invocation argument, select or direct return identifiers in their own ordinary method. Retains original node identities, individual declaration and reference ranges, occurrence multiplicity and explicit binding states. Unknown or ambiguous bindings have null declaration cells. No fields, formal parameters, captures, assignment-target context, initializer evaluation, reaching-value, taint or runtime-flow inference.

Column	Description
Source path	Actual Java compilation-unit source path.
Source set	Actual sole JavaSourceSet name; null for missing or ambiguous source-set markers, independently of project markers; empty preserved.
Project ID	Actual sole JavaProject marker UUID; null for missing or ambiguous project markers. Never normalized or borrowed from another namespace.
Project name	Actual sole JavaProject name; descriptive only. Null and empty values are preserved independently of source-set markers.
Source set ID	Actual sole JavaSourceSet marker UUID; null for missing or ambiguous source-set markers.
Source file ID	Actual compilation-unit UUID in the exact original VCS, model-input and producer namespace. Equal CU IDs alone never establish nested-node identity.
Declaration ID	Actual J.VariableDeclarations UUID only for a unique RESOLVED block-local binding. Null for UNRESOLVED or AMBIGUOUS; no synthetic declaration identity.
Variable ID	Actual individual NamedVariable UUID only for a unique RESOLVED binding. Multiple declarators retain distinct IDs sharing their actual declaration wrapper. Never a trait-created UUID or JavaType.Variable object identity.
Variable type	Actual declaration JavaType.toString() opaque string for a RESOLVED binding; null for missing or Unknown type and for UNRESOLVED or AMBIGUOUS bindings. Never parsed, evaluated or copied from a reference.
Variable start line	Actual full individual NamedVariable node start from unchanged Coordinates, not the wrapper or a synthetic name span. One-based line; null unless binding is RESOLVED. Initializer syntax in a span does not evaluate its value.
Variable start column	Actual full individual NamedVariable node start from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware; null unless binding is RESOLVED.
Variable end line	Actual exclusive full individual NamedVariable node end from unchanged Coordinates. One-based line; null unless binding is RESOLVED.
Variable end column	Actual exclusive full individual NamedVariable node end from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware; null unless binding is RESOLVED.
Reference ID	Actual bare J.Identifier UUID. Join whole argumentId, outer selectId or direct return expressionId only within the exact verified input, source scope, CU and all four reference coordinates.
Reference role	ARGUMENT for a whole bare ordinary invocation argument, SELECT for a whole bare ordinary invocation select, or RETURN for a whole bare direct ordinary-method returned expression. No wrapper unwrapping, parent-row duplication or target-formal mapping.
Reference name	Actual reference Identifier simple name. Spelling alone never establishes declaration binding; reassignment does not change lexical declaration identity.
Reference start line	Actual bare Identifier start from unchanged Coordinates. One-based line; no generated coordinate.
Reference start column	Actual bare Identifier start from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware.
Reference end line	Actual exclusive bare Identifier end from unchanged Coordinates. One-based line.
Reference end column	Actual exclusive bare Identifier end from unchanged Coordinates. One-based UTF-16 column, tab one, CRLF-aware.
Binding state	RESOLVED for a unique supported actual source-local declaration, UNRESOLVED when safe binding is unavailable, or AMBIGUOUS for multiple surviving distinct declarations. Unresolved and ambiguous rows retain reference facts with null declaration cells.
Binding reason	Stable reason code: UNIQUE_LOCAL_DECLARATION, BINDING_UNAVAILABLE, CONFLICTING_ATTRIBUTION, MULTIPLE_LOCAL_CANDIDATES or UNSUPPORTED_BINDING_LAYOUT. Does not establish initializer values, reaching definitions, taint or runtime flow.

Source files that had results

org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

Export after a run

mod study . --last-recipe-run \
  --data-table org.openrewrite.table.SourcesFileResults

Column	Description
Source path before the run	The source path of the file before the run. null when a source file was created during the run.
Source path after the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changes	In a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changes	The specific recipe that made a change.
Estimated time saving	An estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
Cycle	The recipe cycle in which the change was made.

Source files that had search results

org.openrewrite.table.SearchResults

Search results that were found during the recipe run.

Export after a run

  --data-table org.openrewrite.table.SearchResults

Column	Description
Source path of search result before the run	The source path of the file with the search result markers present.
Source path of search result after run the run	A recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Result	The trimmed printed tree of the LST element that the marker is attached to.
Description	The content of the description of the marker.
Recipe that added the search marker	The specific recipe that added the Search marker.
