34 ;;; Commentary:
36 ;; Never read that diff output again!
37 ;; Apply patch interactively!
38 ;; Merge with ease!
40 ;; This package provides a convenient way of simultaneous browsing through
41 ;; the differences between a pair (or a triple) of files or buffers. The
42 ;; files being compared, file-A, file-B, and file-C (if applicable) are
43 ;; shown in separate windows (side by side, one above the another, or in
44 ;; separate frames), and the differences are highlighted as you step
45 ;; through them. You can also copy difference regions from one buffer to
46 ;; another (and recover old differences if you change your mind).
48 ;; Ediff also supports merging operations on files and buffers, including
49 ;; merging using ancestor versions. Both comparison and merging operations can
50 ;; be performed on directories, i.e., by pairwise comparison of files in those
51 ;; directories.
53 ;; In addition, Ediff can apply a patch to a file and then let you step
54 ;; though both files, the patched and the original one, simultaneously,
55 ;; difference-by-difference. You can even apply a patch right out of a
56 ;; mail buffer, i.e., patches received by mail don't even have to be saved.
57 ;; Since Ediff lets you copy differences between buffers, you can, in
58 ;; effect, apply patches selectively (i.e., you can copy a difference
59 ;; region from file_orig to file, thereby undoing any particular patch that
60 ;; you don't like).
62 ;; Ediff is aware of version control, which lets the user compare
63 ;; files with their older versions. Ediff can also work with remote and
64 ;; compressed files. Details are given below.
66 ;; Finally, Ediff supports directory-level comparison, merging and patching.
67 ;; See the on-line manual for details.
69 ;; This package builds upon the ideas borrowed from emerge.el and several
70 ;; Ediff's functions are adaptations from emerge.el. Much of the functionality
71 ;; Ediff provides is also influenced by emerge.el.
73 ;; The present version of Ediff supersedes Emerge. It provides a superior user
74 ;; interface and has numerous major features not found in Emerge. In
75 ;; particular, it can do patching, and 2-way and 3-way file comparison,
76 ;; merging, and directory operations.
80 ;;; Bugs:
82 ;; 1. The undo command doesn't restore deleted regions well. That is, if
83 ;; you delete all characters in a difference region and then invoke
84 ;; `undo', the reinstated text will most likely be inserted outside of
85 ;; what Ediff thinks is the current difference region. (This problem
86 ;; doesn't seem to exist with XEmacs.)
87 ;;
88 ;; If at any point you feel that difference regions are no longer correct,
89 ;; you can hit '!' to recompute the differences.
91 ;; 2. On a monochrome display, the repertoire of faces with which to
92 ;; highlight fine differences is limited. By default, Ediff is using
93 ;; underlining. However, if the region is already underlined by some other
94 ;; overlays, there is no simple way to temporarily remove that residual
95 ;; underlining. This problem occurs when a buffer is highlighted with
96 ;; hilit19.el or font-lock.el packages. If this residual highlighting gets
97 ;; in the way, you can do the following. Both font-lock.el and hilit19.el
98 ;; provide commands for unhighlighting buffers. You can either place these
99 ;; commands in `ediff-prepare-buffer-hook' (which will unhighlight every
100 ;; buffer used by Ediff) or you can execute them interactively, at any time
101 ;; and on any buffer.
104 ;;; Acknowledgements:
106 ;; Ediff was inspired by Dale R. Worley's <drw@math.mit.edu> emerge.el.
107 ;; Ediff would not have been possible without the help and encouragement of
108 ;; its many users. See Ediff on-line Info for the full list of those who
109 ;; helped. Improved defaults in Ediff file-name reading commands.
