Can you switch to other buffers in Emacs?
In any case, it is important that the control window be active (i.e., be the one receiving the keystrokes) when you use Ediff. You can switch to other Emacs buffers at will and even edit the files currently being compared with Ediff and then switch back to Ediff at any time by activating the appropriate Emacs windows.
What kind of files can I use with Ediff?
Ediff works with remote, compressed, and encrypted files. Ediff supports ange-ftp.el, jka-compr.el, uncompress.el and crypt++.el, but it may work with other similar packages as well. This means that you can compare files residing on another machine, or you can apply a patch to a file on another machine.
How to compare large regions in Ediff file?
To compare very large regions, use ediff-regions-linewise. This command displays differences much like ediff-files and ediff-buffers. The functions ediff-patch-file and ediff-patch-buffer apply a patch to a file or a buffer and then run Ediff on the appropriate files/buffers, displaying the difference regions.
Which is the best way to use Ediff?
By default ediff spawns a new frame to display files to be compared or merged. Some prefer to just use the selected frame. Also it splits window vertically to display files and one might find it hard to perceive provided information in such way. In such a case horizontal splitting is more attractive.
How are comparison and merging operations performed in Ediff?
Both comparison and merging operations can be performed on directories, i.e. by pairwise comparison of files in those directories. In addition Ediff can apply a patch to a file and then let you step through both files, the patched and the original one, simultaneously, difference-by-difference.
Can you apply a patch to a file in Ediff?
In addition Ediff can apply a patch to a file and then let you step through both files, the patched and the original one, simultaneously, difference-by-difference. You can even apply a patch right out of a mail buffer, i.e. patches received by mail don’t even have to be saved.
