Selective BrowsingUp: I’ve learnt to love it because hey, what’s an OS other than a bootstrap loader for emacs right? If you’ve been cruising along in Ediff and suddenly find edkff commands aren’t working, you’ve probably accidentally clicked on the differences window and are typing in one of the buffers directly, or perhaps you used an Ediff command that switched the window focus on you unexpectedly.

Of course, to make changes to a buffer, it cannot be in read-only mode. Brains are for thinking, what’s magit? Or why cells are freaking amazing.

Eediff working with any version control system, you sometimes want to compare different revisions of a file. Oh no I got lost somewhere!

You will mostly use the “Manipulate” commands. In its default configuration, the control window is designed to be small enough not to get in the way on smaller displays.

Thanks for the pointer. Inside the red zone are two bright red highlighted areas. Let’s get gritty, edit buffer B by hand. The most likely explanation is historical; vc-diff has been around longer than Ediff, and it would have been disruptive to long-standing users of Emacs if a strange new interface was unexpectedly foisted on them.

Recenter the comparison buffers on the difference nearest to your current location point in the specified buffer.

In addition to the expected pair of buffers showing you the two files or revisions being compared, it pops open a small “control window” see Figure in which you type commands. In its default configuration, this is a separate operating mxnual window or what Emacs refers to as a “frame”.

Window and Frame ConfigurationUp: How can I get back to ediff-mode from this edit kind of mode? Refinement of Difference RegionsUp: I present to you, Ediff for the brainically challenged:. If, after editing one of the comparison buffers for a while, kanual like to return to viewing differences, starting with the difference nearest to your edit location, click in the control window and type g followed manuaal the letter assigned to the buffer in which you’re interested as discussed earlier in “Making Changes”.

Ediff prompts you for the file you’d like to compare defaulting to the file associated with the current bufferand the revision s you’d like to compare, defaulting to the version last checked in and the current state of the buffer. Ediff will also sometimes give you 3 if there was a merge conflict the current branch, the merging branch and the final resulting file.


Stop, wait a minute, fill my cup put some liquor in it.

This is much more helpful than the traditional diff mode, making it worthwhile learning the strange new interface. The exception as mentioned above is if you ask Emacs for help resolving conflicts when they occur during a check-in operation or manually invoke vc-resolve-conflicts while visiting a buffer containing such conflicts.

See how ediff yellow region has the variants, and is named application.

Following along in our example, if after changing buffer B like this, you change your mind and want to edff its old state, you can type r b for “restore buffer B “. Make sure to undo the stray characters you’ve typed into the comparison buffer, then click on the control window and start issuing commands again.

See “Recovering from Confusion” later in this chapter. What Emacs calls a ” window ” is a possibly full-frame pane of a frame. Important commands available in Ediff are summarized in Table Registry of Ediff SessionsUp: Manusl white zones are places where changes exist.

I can’t think of it’s name. Magit is a cool wrapper around git for emacs.
