30 ;;; Commentary:
|
|
|
31
|
|
|
32 ;; Never read that diff output again!
|
|
|
33 ;; Apply patch interactively!
|
|
|
34 ;; Merge with ease!
|
|
|
35
|
|
|
36 ;; This package provides a convenient way of simultaneous browsing through
|
|
|
37 ;; the differences between a pair (or a triple) of files or buffers. The
|
|
|
38 ;; files being compared, file-A, file-B, and file-C (if applicable) are
|
|
|
39 ;; shown in separate windows (side by side, one above the another, or in
|
|
|
40 ;; separate frames), and the differences are highlighted as you step
|
|
|
41 ;; through them. You can also copy difference regions from one buffer to
|
|
|
42 ;; another (and recover old differences if you change your mind).
|
|
|
43
|
|
|
44 ;; Ediff also supports merging operations on files and buffers, including
|
|
|
45 ;; merging using ancestor versions. Both comparison and merging operations can
|
|
|
46 ;; be performed on directories, i.e., by pairwise comparison of files in those
|
|
|
47 ;; directories.
|
|
|
48
|
|
|
49 ;; In addition, Ediff can apply a patch to a file and then let you step
|
|
|
50 ;; though both files, the patched and the original one, simultaneously,
|
|
|
51 ;; difference-by-difference. You can even apply a patch right out of a
|
|
|
52 ;; mail buffer, i.e., patches received by mail don't even have to be saved.
|
|
|
53 ;; Since Ediff lets you copy differences between buffers, you can, in
|
|
|
54 ;; effect, apply patches selectively (i.e., you can copy a difference
|
|
|
55 ;; region from file_orig to file, thereby undoing any particular patch that
|
|
|
56 ;; you don't like).
|
|
|
57
|
|
|
58 ;; Ediff is aware of version control, which lets the user compare
|
|
|
59 ;; files with their older versions. Ediff can also work with remote and
|
|
|
60 ;; compressed files. Details are given below.
|
|
|
61
|
|
|
62 ;; Finally, Ediff supports directory-level comparison, merging and patching.
|
|
|
63 ;; See the on-line manual for details.
|
|
|
64
|
|
|
65 ;; This package builds upon the ideas borrowed from emerge.el and several
|
|
|
66 ;; Ediff's functions are adaptations from emerge.el. Much of the functionality
|
|
|
67 ;; Ediff provides is also influenced by emerge.el.
|
|
|
68
|
|
|
69 ;; The present version of Ediff supersedes Emerge. It provides a superior user
|
|
|
70 ;; interface and has numerous major features not found in Emerge. In
|
|
|
71 ;; particular, it can do patching, and 2-way and 3-way file comparison,
|
|
|
72 ;; merging, and directory operations.

76 ;;; Bugs:
|
|
|
77
|
|
|
78 ;; 1. The undo command doesn't restore deleted regions well. That is, if
|
|
|
79 ;; you delete all characters in a difference region and then invoke
|
|
|
80 ;; `undo', the reinstated text will most likely be inserted outside of
|
|
|
81 ;; what Ediff thinks is the current difference region. (This problem
|
|
|
82 ;; doesn't seem to exist with XEmacs.)
|
|
|
83 ;;
|
|
|
84 ;; If at any point you feel that difference regions are no longer correct,
|
|
|
85 ;; you can hit '!' to recompute the differences.
|
|
|
86
|
|
|
87 ;; 2. On a monochrome display, the repertoire of faces with which to
|
|
|
88 ;; highlight fine differences is limited. By default, Ediff is using
|
|
|
89 ;; underlining. However, if the region is already underlined by some other
|
|
|
90 ;; overlays, there is no simple way to temporarily remove that residual
|
|
|
91 ;; underlining. This problem occurs when a buffer is highlighted with
|
|
|
92 ;; hilit19.el or font-lock.el packages. If this residual highlighting gets
|
|
|
93 ;; in the way, you can do the following. Both font-lock.el and hilit19.el
|
|
|
94 ;; provide commands for unhighlighting buffers. You can either place these
|
|
|
95 ;; commands in `ediff-prepare-buffer-hook' (which will unhighlight every
|
|
|
96 ;; buffer used by Ediff) or you can execute them interactively, at any time
|
|
|
97 ;; and on any buffer.

104 ;; its many users. See Ediff on-line Info for the full list of those who

105 ;; helped. Improved defaults in Ediff file-name reading commands.
