The idea of this function is to return the number of words in the current buffer. This number is then displayed on the status line. This should work nicely as the statusline is updated at just about every possible opportunity so the count will always remain 'live'. \n\nThe problem is that the function I have currently defined is slow and so vim is obviously sluggish when it is used for all but the smallest files; due to this function being executed so frequently.\n\nIn summary, does anyone have a clever trick for producing a function that is blazingly fast at calculating the number of words in the current buffer and returning the result?" ]

[ "GetGeotagAsync fails on files from a list created via Folder.CreateFileQueryWithOptions w/ OrderByName", "Objective: get a list of image files from a user specified folder and retrieve the latitude/longitude metadata for each file if available.\n\nThe approach is to use Folder query with options to return a list of files which are then iterated over to get the geotag info. As a simple test I just added some code to the Geotag sample provided by MS; ChooseFolderButton_Click method added. It uses FolderPicker then simply picks the first file from the query (just as a test) and treats it like the original demo does to display geotag info.\n\nThe problem appears to be with how the StorageFile items are returned from the query AND only when CommonFileQuery.OrderByName is used. If DefaultQuery is used then all works.\n\nHere is the code added to MS Samples Geotag (a button was added to the XAML):\n\nprivate async void ChooseFolderButton_Click()\n{\n FolderPicker picker = new FolderPicker\n {\n SuggestedStartLocation = PickerLocationId.PicturesLibrary,\n CommitButtonText = \"Select\",\n ViewMode = PickerViewMode.Thumbnail,\n };\n picker.FileTypeFilter.Add(\"*\");\n StorageFolder Folder = await picker.PickSingleFolderAsync();\n\n if (Folder != null) { \n // Get the files and sort them myself\n IReadOnlyList<StorageFile> files = await Folder.GetFilesAsync();\n List<StorageFile> sortedList = files.Where(f => string.Compare(f.FileType,\".jpg\", ignoreCase: true) == 0 )\n .OrderBy(f => f.DisplayName)\n .Select(f => f)\n .ToList();\n file = sortedList.FirstOrDefault();\n }\n\n if (Folder != null) {\n // Use Folder GetFiles with query options to get sorted list\n var queryOptions = new QueryOptions(CommonFileQuery.DefaultQuery, new List<string> { \".jpg\" })\n {\n FolderDepth = FolderDepth.Shallow\n };\n //queryOptions.SetPropertyPrefetch(PropertyPrefetchOptions.ImageProperties, null);\n IReadOnlyList<StorageFile> files2 = await Folder.CreateFileQueryWithOptions(queryOptions).GetFilesAsync();\n var file2 = files2[0];\n }\n\n if (Folder != null && file != null)\n {\n FileDisplayName.Text = file.DisplayName;\n FileOperationsPanel.Visibility = Visibility.Visible;\n }\n else\n {\n FileOperationsPanel.Visibility = Visibility.Collapsed;\n }\n}\n\n\nSelecting the file from sortedList works fine. Using the result from files2 will also work when DefaultQuery is used as shown. Change it to OrderByName and the GetGeotagAsync call will fail, returning null.\n\nLooking into it in detail, it appears the StorageFile instance returned is different in this last case. The FolderRelativeId has the file extension duplicated; numbers\\filename.ext.ext ; however, access through the StorageFile instance seems to work otherwise... except for GetGeotagAsync() at a minimum. This makes me wonder if a copy of the files are being created and the metadata is not included.\n\nI am relatively new to C# and UWP and this is my first question post so I hope this is enough detail... The Question is basically: Am I missing something here? Doing something wrong in the Folder Query? I can work around it using linq as I did in the example code, or even just use DefaultQuery; yet this is uncomfortable as I do use the folder query approach in several other things. Does query OrderByName duplicate or do something undesireable?" ]
