4-4: Summary: Effective caching mechanism implemented for Windows drive listingThe changes introduce a caching mechanism for the
list_drivesfunction on Windows, which should significantly improve performance, especially in scenarios involving disconnected network drives. This implementation directly addresses the objectives outlined in the PR and should help resolve the freezing issue described in #501.Key points:
- The
Lambdamodule is imported for cache management.- A cache variable is initialized and checked before executing the
wmiccommand.- The cache is updated with the latest results after each execution.
These changes are well-structured, consistent with the existing codebase, and should provide a noticeable performance improvement for Windows users of the Fern plugin.
To further enhance this implementation, consider:
- Implementing a cache invalidation mechanism (as suggested in a previous comment).
- Adding a configurable cache expiration time to ensure that the cached drive list doesn't become stale over extended periods.
- Providing a way for users to manually refresh the drive list if needed.
These additions would make the caching mechanism more robust and flexible for various use cases.

4-4: LGTM: Lambda module import addedThe addition of the
Lambdamodule import is consistent with the existing import style and is necessary for the new caching mechanism implemented later in the file.
61-61: LGTM: Cache initialization addedThe cache initialization is correctly placed within the Windows-specific section and uses
v:nullto indicate an unset cache, which is appropriate.

🛠️ Refactor suggestion
LGTM: Caching mechanism implemented for list_drives
The caching mechanism for the list_drives function is well-implemented and addresses the performance issue described in the PR objectives. This should help mitigate the freezing issue described in the linked issue #501, especially when dealing with disconnected network drives.
A minor suggestion for improvement:
Consider adding a cache invalidation mechanism or a way to refresh the cache. This could be useful in scenarios where drive configurations change dynamically. For example:
function! fern#scheme#file#util#invalidate_drives_cache() abort
let s:list_drives_cache = v:null
endfunctionThis function could be called when necessary to force a refresh of the drives list.
