frontend/app/store/global.ts (1)
317-318: Clarify function comment.At line 317, the function name matches the new usage pattern. At line 318, confirm that retrieving the atom from the cache is the desired approach for repeated retrieval. Consider adding a bit more documentation about the caching strategy and its effect on reactivity.
frontend/util/util.ts (2)
46-48: Add clarifying docstring.The comments outline the usage, but consider adding a formal docstring describing parameters and return values for clarity.
49-59: Efficient caching approach.This function should significantly reduce unnecessary recomputations. However, if
JSON.stringifyusage becomes costly for large objects, consider a more optimized deep-equality approach or a hashing technique.

9-9: Good usage of the newly introduced getSettingsPrefixAtom.
Replacing a hook-based approach with a direct atom retrieval improves clarity and can minimize re-renders driven by hooks. Keep consistent naming conventions across the codebase.
126-126: Ensure all previous references to useSettingsPrefixAtom are safely migrated.
Since you're now assigning windowSettingsAtom = getSettingsPrefixAtom("window"), confirm no references to the old function remain and that no usage patterns depended on hook-based reactivity.

13-13: Import usage looks correct.
The new deepCompareReturnPrev import is properly placed, aligning with the existing import structure.
320-321: Key usage is sound.
Defining cacheKey = {} for each prefix ensures a unique reference bound to each prefix, which is a nice workaround for simpler identity checks.
324-325: Validate fallback when prefix is empty or not found.
Using getPrefixedSettings appropriately narrows down relevant settings. Returning the result of deepCompareReturnPrev helps avoid unnecessary updates, but be sure to confirm that an empty prefix returns valid or empty objects as intended.
676-676: Export statement completes the refactor.
This ensures external modules can consume getSettingsPrefixAtom consistently. No issues observed.
frontend/app/view/term/term.tsx (2)
20-20: Correct import for the new atom function.
Replacing useSettingsPrefixAtom with getSettingsPrefixAtom helps align with other parts of the refactor.
776-776: Confirm that a one-time retrieval pattern is acceptable here.
This approach indicates a one-time or stable reference. If you need dynamic updates or reactivity, confirm a purely atom-based approach is sufficient.
frontend/util/util.ts (2)
8-8: Establishing prevValueCache.
A WeakMap is an excellent choice for preventing memory leaks, especially when keys become unreferenced.
312-312: Export is consistent with naming.
Including deepCompareReturnPrev in exports allows it to be reused across the codebase. No issues detected.
