Rename Refs

Rename Refs

Atomically rename one Python symbol/module: definition, __all__ exports, caller imports/calls (fn-rdeps plus line ranges), Sphinx refs in .py/.rst, optional pyDeprecate alias, or hard delete only with exhaustive zero callers.

Interface

• symbol <old_qname> <new_qname>: function/class/method. qname is bare (MyClass) or qualified (MyClass.method), matched to symbol-local qualified_name. The module-qualified form (module::symbol) is not accepted by find-symbol and returns zero matches. Build <module>::<qualified_name> only for Step 2 fn-rdeps.
• module <old_module_path> <new_module_path>: dotted paths; rename file and imports.
• --dry-run: list sites, no edit.
• --deprecate[=<decorator>]: symbol only; old-name pyDeprecate @deprecated wrapper to new name; pyDeprecate required.
• --since <ver> / --removed-in <ver>: decorator versions, default "?".
• --remove-if-no-callers: symbol only; delete only with exhaustive zero callers.

Reject --deprecate with --remove-if-no-callers before analysis. Static limits: report a getattr(obj, "old_name") search advisory; cross-repo callers require --deprecate plus a SemVer bump for public API.

NOT for: index build ($codemap-py:scan-codebase); query without rename intent ($codemap-py:query-code); non-Python; ABC/Protocol override renames (static imports do not track overrides—review fn-rdeps, then rename overrides explicitly). No --index <path>; use default project index. For monorepo packages, first run $codemap-py:scan-codebase --root <pkg>.

Runtime note

Codex has no bin/ PATH entry or plugin-root variable. Resolve the installed root once, substitute PLUGIN_ROOT, and retain it in reasoning; shell state does not persist. Codex has no AskUserQuestion: state choices in chat and wait for the next user message.

Workflow

1. Parse and check freshness

Accept only the listed flags; reject other -- tokens, and the incompatible pair. Then run:

PLUGIN_ROOT/bin/codemap-py query find-symbol "<old_ref>" --limit 0

Keep that result for Step 2. index.stale: true means mismatch; index.query_complete: false plus index.completeness_reason: "stale" corroborates. Ask to proceed with possibly incomplete callers or abort and re-run $codemap-py:scan-codebase. If the index block is absent, warn and proceed cautiously; never assume fresh.

2. Resolve targets

For symbol, reuse matches; each has {name, qualified_name, type, module, path, start_line, end_line, source}. Use path/lines for edits and qualified_name for exact filtering. Zero: report Symbol '<old_ref>' not found and stop. Multiple: list name/type/module/path, ask selection, wait. Then query:

PLUGIN_ROOT/bin/codemap-py query fn-rdeps "<module>::<qualified_name>"

It returns {qname, called_by:[{caller, module, path}], count, index:{query_complete,...}}; resolve caller line ranges via query symbol <caller> in Step 4. Read completeness forward-first: index.query_complete, then legacy index.exhaustive only if absent; not complete belongs in the report.

For module, query:

PLUGIN_ROOT/bin/codemap-py query rdeps "<old_module_path>"

Read completeness identically. Honor --remove-if-no-callers only when passed and complete.

3. Report and confirm

Print old→new, type/definition (symbol), static caller count/files, Step 4 doc-ref search, and getattr/cross-repo limits. If incomplete: "index non-exhaustive — some callers may not appear above."

With >50 callers, write full list to .reports/codex/codemap-py/rename-refs-blast-<branch>-<YYYY-MM-DD>.md, print it, edit first 50 only, and call 51–N "skipped callers" in Step 6. <branch> is git branch --show-current | tr '/' '-' (main if empty/detached). Never overwrite: append -2, -3, … until free; this file is the manual-edit record.

For --remove-if-no-callers, before edits: callers found → report count and stop (remove callers first or drop the flag); incomplete/missing completeness → report $codemap-py:scan-codebase required and stop; complete zero → ask delete/abort. Before deletion, verify start_line names the expected symbol; mismatch aborts. Delete definition plus preceding decorators, skip Step 4, and continue at Step 6.

For --dry-run, write would-change sites to .reports/codex/codemap-py/rename-refs-dry-<branch>-<YYYY-MM-DD>.md using the same branch and never-overwrite rule; print path, ask for re-invocation without --dry-run or stop. Otherwise ask apply/abort and stop on abort.

4. Apply symbol edits

1. At start_line, rename def old_name( / class OldName(...) / class OldName:; for methods, match inside class. Rename @old_name.setter/.deleter too: an orphaned descriptor raises AttributeError at class definition. Rename @typing.overload def old_name( in the file and sibling .pyi; find-symbol omits these.
2. In package __init__.py, rename quoted old names in __all__.
3. For each called_by, run PLUGIN_ROOT/bin/codemap-py query symbol "<caller_qname>"; within its range, fix each file's module import once, then qualified X.old_name( and bare old_name(. Never bare-replace outside the confirmed range. Warn/skip a caller absent from the index.
4. Search .py/.rst Sphinx :func:/:class:/:meth:/:mod:/:attr: old-name roles; edit only matching module context.
5. For --deprecate, after definition rename run PLUGIN_ROOT/bin/gen_deprecation_wrapper.py; insert after new definition. It maps class to @deprecated_class(target=NewName, ...) (keeps isinstance) and function/method to @deprecated(target=new_fn, ...). Missing pyDeprecate makes target import fail; report advisory in Step 6.

5. Apply module edits

1. Refuse non-git, untracked, or uncommitted source; require add/commit/stash. git mv <old_file_path> <new_file_path>, preferring indexed path over dotted conversion (which can be wrong under src/ layouts). Package directories (__init__.py) are out of scope: print direct git mv, do not attempt.
2. Rename direct import mypackage.old_name (including as X) and from mypackage.old_name import ....
3. Rename same-package __init__.py from .old_name import ... after directory check.
4. Search full dotted path in pyproject.toml/setup.cfg, editing package/install requirements only; never bare basename.
5. Rename Sphinx :mod: full paths; basename fallback needs matching module context.

6. Re-scan and summary

PLUGIN_ROOT/bin/codemap-py index --incremental
PLUGIN_ROOT/bin/codemap-py query find-symbol "<old_ref>" --limit 0    # symbol
PLUGIN_ROOT/bin/codemap-py query rdeps "<old_ref>"                     # module

If re-scan fails, report it; results are advisory, not authoritative. Expect old name absent except deprecated alias. List other residual files as advisory (dynamic/string/template/out-of-scope refs). Report renamed pair, files, calls, doc refs, alias path/line when used; always flag getattr literal search, external consumers without alias, skipped callers, and residual hits when applicable.
