Emacs has a really nice mode for applying and navigating hunks of a diff file: Diff-Mode
However, there doesn't seem to be a way to apply the full diff when in this mode. Is this just so obvious that I missed it?

There doesn't seem to be a function that does that.
You can get that functionality by using a macro. First, hit F3 C-c C-a F4 to define a macro that applies a hunk, and then type C-u 0 M-x kmacro-call-macro to repeatedly call that macro until an error occurs (probably at the end of the diff file).
- it'd be pretty nice if
Diff-Modewas a single keystroke interface... no need for theC-c C-prefix.

WRT to a command applying the whole diff, I'd welcome a patch that implements it.Stefan– Stefan2016-01-26 04:26:38 +00:00Commented Jan 26, 2016 at 4:26
- @Stefan excellent! Where are the docs for read-only mode commands? I'd like to make diffs read-only by default. BTW, we're using diff-mode as the interface for refactorings in ensime :-)fommil– fommil2016-01-26 09:02:37 +00:00Commented Jan 26, 2016 at 9:02

C-h f diff-mode-shared-mapand then follow the link to the source code. This map is bound to ESC (aka the Meta modifier) normally but is also used without prefix when the buffer is read-only.Stefan– Stefan2016-01-26 13:00:02 +00:00Commented Jan 26, 2016 at 13:00 - it must be
C-h v diff-mode-shared-mapbecause it is a variable and not a function.Uwe Koloska– Uwe Koloska2016-07-08 16:22:07 +00:00Commented Jul 8, 2016 at 16:22
