|
||
|
||
;;; Commentary:
|
||
|
||
;; Never read that diff output again!
|
||
;; Apply patch interactively!
|
||
;; Merge with ease!
|
||
|
||
;; This package provides a convenient way of simultaneous browsing through
|
||
;; the differences between a pair (or a triple) of files or buffers. The
|
||
;; files being compared, file-A, file-B, and file-C (if applicable) are
|
||
;; shown in separate windows (side by side, one above the another, or in
|
||
;; separate frames), and the differences are highlighted as you step
|
||
;; through them. You can also copy difference regions from one buffer to
|
||
;; another (and recover old differences if you change your mind).
|
||
|
||
;; Ediff also supports merging operations on files and buffers, including
|
||
;; merging using ancestor versions. 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
|
||
;; though 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.
|
||
;; Since Ediff lets you copy differences between buffers, you can, in
|
||
;; effect, apply patches selectively (i.e., you can copy a difference
|
||
;; region from file_orig to file, thereby undoing any particular patch that
|
||
;; you don't like).
|
||
|
||
;; Ediff is aware of version control, which lets the user compare
|
||
;; files with their older versions. Ediff can also work with remote and
|
||
;; compressed files. Details are given below.
|
||
|
||
;; Finally, Ediff supports directory-level comparison, merging and patching.
|
||
;; See the on-line manual for details.
|
||
|
||
;; This package builds upon the ideas borrowed from emerge.el and several
|
||
;; Ediff's functions are adaptations from emerge.el. Much of the functionality
|
||
;; Ediff provides is also influenced by emerge.el.
|
||
|
||
;; The present version of Ediff supersedes Emerge. It provides a superior user
|
||
;; interface and has numerous major features not found in Emerge. In
|
||
;; particular, it can do patching, and 2-way and 3-way file comparison,
|
||
;; merging, and directory operations.
|
||
|
||
|
||
|
||
;;; Bugs:
|
||
|
||
;; 1. The undo command doesn't restore deleted regions well. That is, if
|
||
;; you delete all characters in a difference region and then invoke
|
||
;; `undo', the reinstated text will most likely be inserted outside of
|
||
;; what Ediff thinks is the current difference region. (This problem
|
||
;; doesn't seem to exist with XEmacs.)
|
||
;;
|
||
;; If at any point you feel that difference regions are no longer correct,
|
||
;; you can hit '!' to recompute the differences.
|
||
|
||
;; 2. On a monochrome display, the repertoire of faces with which to
|
||
;; highlight fine differences is limited. By default, Ediff is using
|
||
;; underlining. However, if the region is already underlined by some other
|
||
;; overlays, there is no simple way to temporarily remove that residual
|
||
;; underlining. This problem occurs when a buffer is highlighted with
|
||
;; hilit19.el or font-lock.el packages. If this residual highlighting gets
|
||
;; in the way, you can do the following. Both font-lock.el and hilit19.el
|
||
;; provide commands for unhighlighting buffers. You can either place these
|
||
;; commands in `ediff-prepare-buffer-hook' (which will unhighlight every
|
||
;; buffer used by Ediff) or you can execute them interactively, at any time
|
||
;; and on any buffer.
|
||
|
||
|
||
;;; Acknowledgements:
|
||
|
||
;; Ediff was inspired by Dale R. Worley's <drw@math.mit.edu> emerge.el.
|
||
;; Ediff would not have been possible without the help and encouragement of
|
||
;; its many users. See Ediff on-line Info for the full list of those who
|
||
;; helped. Improved defaults in Ediff file-name reading commands.
