问题
I am using Eclipse (Photon 4.8.0) for a Git project. Before committing, I have been double clicking the files which appear in the unstaged changes section of the Git Staging View to remind myself of what I have changed before writing the commit message (I'm still new to Git so occasionally I will do several things before remembering that I have to commit my changes). However, double clicking on the file today merely opens the file, rather than opening the comparison view. I can still open the comparison view by right clicking the file and selecting Compare with Index but this takes more time and is frustrating.
As far as I know, I haven't changed any settings (not intentionally anyway). Can someone explain to me how to get back the behaviour I was seeing before please?
回答1:
Make sure, in the Git Staging view toolbar the
Compare Mode button is pressed.
See also EGit User Guide of the History view with the same icon.
