|
|
|
26 ;; Users are encouraged to add functionality to this file.
|
|
|
27 ;; The present file contains all the infrastructure needed for that.
|
|
|
28 ;;
|
|
|
29 ;; Generally, to to implement a new multisession capability within Ediff,
|
|
|
30 ;; you need to tell it
|
|
|
31 ;;
|
|
|
32 ;; 1. How to display the session group buffer.
|
|
|
33 ;; This function must indicate which Ediff sessions are active (+) and
|
|
|
34 ;; which are finished (-).
|
|
|
35 ;; See ediff-redraw-directory-group-buffer for an example.
|
|
|
36 ;; In all likelihood, ediff-redraw-directory-group-buffer can be used
|
|
|
37 ;; directly or after a small modification.
|
|
|
38 ;; 2. What action to take when the user clicks button 2 or types v,e, or
|
|
|
39 ;; RET. See ediff-filegroup-action.
|
|
|
40 ;; 3. Provide a list of pairs or triples of file names (or buffers,
|
|
|
41 ;; depending on the particular Ediff operation you want to invoke)
|
|
|
42 ;; in the following format:
|
|
|
43 ;; (descriptor (obj1 obj2 obj3) (...) ...)
|
|
|
44 ;; Actually, the format of this list is pretty much up to the
|
|
|
45 ;; developer. The only thing is that it must be a list of lists,
|
|
|
46 ;; and the first list must describe the meta session, and subsequent
|
|
|
47 ;; elements must describe individual sessions.
|
|
|
48 ;; This descriptor must be a list of two, three, or four elements (nil
|
|
|
49 ;; or string). The function ediff-redraw-registry-buffer displays the
|
|
|
50 ;; second through last of these in the registry buffer.
|
|
|
51 ;; Also, keep in mind that the function ediff-prepare-meta-buffer
|
|
|
52 ;; (which see) prepends the session group buffer to the descriptor and
|
|
|
53 ;; nil in front of each subsequent list (i.e., the above list
|
|
|
54 ;; will become
|
|
|
55 ;; ((meta-buf descriptor) (nil obj1 obj2 obj3) (nil ...) ...)
|
|
|
56 ;; Ediff expects that your function (in 2 above) will arrange to
|
|
|
57 ;; replace this prepended nil (via setcar) with the actual ediff
|
|
|
58 ;; control buffer associated with an appropriate Ediff session.
|
|
|
59 ;; This is arranged through internal startup hooks that can be passed
|
|
|
60 ;; to any of Ediff major entries (such as ediff-files, epatch, etc.).
|
|
|
61 ;; See how this is done in ediff-filegroup-action.
|
|
|
62 ;;
|
|
|
63 ;; Session descriptions are of the form (obj1 obj2 obj3), which
|
|
|
64 ;; describe objects relevant to the session. Usually they are names of
|
|
|
65 ;; files, but sometimes they may be other things. For instance, obj3 is
|
|
|
66 ;; nil for jobs that involve only two files. For patch jobs, obj2 and
|
|
|
67 ;; obj3 are markers that specify the patch corresponding to the file
|
|
|
68 ;; (whose name is obj1).
|
|
|
69 ;; 4. Write a function that makes a call to ediff-prepare-meta-buffer
|
|
|
70 ;; passing all this info.
|
|
|
71 ;; You may be able to use ediff-directories-internal as a template.
|
|
|
72 ;; 5. If you intend to add several related pieces of functionality,
|
|
|
73 ;; you may want to keep the function in 4 as an internal version
|
|
|
74 ;; and then write several top-level interactive functions that call it
|
|
|
75 ;; with different parameters.
|
|
|
76 ;; See how ediff-directories, ediff-merge-directories, and
|
|
|
77 ;; ediff-merge-directories-with-ancestor all use
|
|
|
78 ;; ediff-directories-internal.
|
|
|
79 ;;
|
|
|
80 ;; A useful addition here could be session groups selected by patterns
|
|
|
81 ;; (which are different in each directory). For instance, one may want to
|
|
|
82 ;; compare files of the form abc{something}.c to files old{something}.d
|
|
|
83 ;; which may be in the same or different directories. Or, one may want to
|
|
|
84 ;; compare all files of the form {something} to files of the form {something}~.
|
|
|
85 ;;
|
|
|
86 ;; Implementing this requires writing an collating function, which should pair
|
|
|
87 ;; up appropriate files. It will also require a generalization of the functions
|
|
|
88 ;; that do the layout of the meta- and differences buffers and of
|
|
|
89 ;; ediff-filegroup-action.
