In the previous post, I showed you how to use Visual Studio to compare 2 files. I also use Visual Studio Code from time to time. And, as every great IDE, Visual Studio Code also have a great diff tool. As with Visual Studio, you can use it to compare 2 versions of the same file if you use a source control. But you can also compare 2 files from your file system.
There are multiple ways to use the Visual Studio Code diff tool:
#Comparing files using the User Interface
- Open the 2 files in Visual Studio Code
- Right click on one file and click "Select for compare"
- Right click on the other file and click "Compare file file1 with file2"
You should see the result:
#Comparing files using the command line
- Using Visual Studio Code
"%LOCALAPPDATA%\Programs\Microsoft VS Code\code.exe" --diff file1.cs file2.cs
- Using Visual Studio Code Insiders
"%LOCALAPPDATA%\Programs\Microsoft VS Code Insiders\Code - Insiders.exe" --diff file1.cs file2.cs
#Using Visual Studio Code as a git difftool
git difftool is a Git command that allows you to compare and edit files between revisions using common diff tools. You can use any editor that support diff such as VS Code. Open a command prompt and use the following commands:
git config --global diff.tool vscode git config --global difftool.vscode.cmd "code --wait --diff $LOCAL $REMOTE"
By the way, you can also use Visual Studio Code as your git editor:
git config --global core.editor "code --wait"
