We use git as our source control system, so we don’t have p4merge installed on our machines, but we do have Visual Studio Code installed as a core app and we want to use that as our primary text diff tool.
The current flow of opening the text diff tool is to launch the app with two arguments for the files (eg. “code.exe file1.txt file2.txt”). For VSCode this results in the app launching, but two different tabs opening instead of the diff view. To open the diff view, the “--diff”/“-d” arg needs to be provided.
I’ve created and submitted a PR that supports supplying custom text diff tool args so that any tool which requires basic arguments to open the diff view will work (eg. “code.exe file1.txt file2.txt --diff”). Unfortunately, there is no nice in editor field that can be modified to set this and the user must modify the ini file directly.
