Public int GetHashCode(System.IO.FileInfo fi)Ĭreate a C# console application project, with using directives for the System.Linq and System.IO namespaces. reference identity, it is possible that two or more objects will produce the same Because equality as defined here is a simple value equality, not rules for IEqualit圜omparer, if Equals is true, then the hash codes must Return a hash that reflects the comparison criteria. Public bool Equals(System.IO.FileInfo f1, System.IO.FileInfo f2) 1) Select New Folder Comparison command in File menu 2) Specify folder to compare on both - left and right panel. of the files being compared and their length in bytes.Ĭlass FileCompare : 圜omparer This implementation defines a very simple comparison Keep the console window open in debug mode.Ĭonsole.WriteLine("Press any key to exit.") Select file).Except(list2, myFileCompare) Ĭonsole.WriteLine("The following files are in list1 but not list2:") For this example we only check one way. If you don't specify any command-line options, comp uses the ones you specified before. When you press Y, you're prompted for which command-line options to use. Find the set difference between the two folders. The comp command prompts you for the locations and names of the new files. Var quer圜ommonFiles = list1.Intersect(list2, myFileCompare) Ĭonsole.WriteLine("The following files are in both folders:") Ĭonsole.WriteLine(v.FullName) //shows which items end up in result listĬonsole.WriteLine("There are no common files in the two folders.") The query executes immediately because it returns a bool.īool areIdentical = list1.SequenceEqual(list2, myFileCompare) Ĭonsole.WriteLine("the two folders are the same") Ĭonsole.WriteLine("The two folders are not the same") that is defined in the FileCompare class. identical file lists, based on the custom file comparer This query determines whether the two folders contain IEnumerable list2 = dir2.GetFiles("*.*", System.IO.SearchOption.AllDirectories) įileCompare myFileCompare = new FileCompare() IEnumerable list1 = dir1.GetFiles("*.*", System.IO.SearchOption.AllDirectories) System.IO.DirectoryInfo dir2 = new System.IO.DirectoryInfo(pathB) String pathA = pathB = dir1 = new System.IO.DirectoryInfo(pathA) on a local drive and change these file paths. b Ignores trailing blanks (spaces and tabs) and treats other strings. For more option use man diff on your unix box. Since directory is also a type of file, the differences between two directories can easily be figure out by using diff commands. Create two identical or different temporary folders Diff command in Unix is used to find the differences between files (all types). In a real-world scenario, you should modify this comparer to perform a more rigorous equality check. It just uses the name and length in bytes of each file to determine whether the contents of each folder are identical or not. The class is not intended for use in real-world scenarios. ![]() The FileComparer class shown here demonstrates how to use a custom comparer class together with the Standard Query Operators. In the next post, I’ll show the real approach that present a list of all the changes and let the user to pick them one by one.The techniques shown here can be adapted to compare sequences of objects of any type. This code meant to simplify the explanation and to show only how to use the package and the diff API. Notice that currently, it takes only the first pair. await ('vscode.diff', (diffs), (diffs), 'My great Diff' ) Using the vscode command vscode.diff the extension opens a diff view with the contents of both of the files. So: How to add a command to commands palette in vscode extension?īasically it well explained in the docs so let’s do it quickįirst, we need to add a entity in package.json root "contributes": `]) Īnd finally How to ask vscode to display a “compare” view? Once they chosen, the plugin will run the code that compare them. In order to let the users to compare folders, we need to allow them to run a command that will open the “choose a folder” dialog so they could choose a folder from their file system. Like promised, the post will includes an explanation about the product challenge and how to solve it. In the last post, we talked about the plugin, the requirements and the motivations.
