;;; Commentary:
|
|
|
|
;; Users are encouraged to add functionality to this file.
|
|
;; The present file contains all the infrastructure needed for that.
|
|
;;
|
|
;; Generally, to implement a new multisession capability within Ediff,
|
|
;; you need to tell it
|
|
;;
|
|
;; 1. How to display the session group buffer.
|
|
;; This function must indicate which Ediff sessions are active (+) and
|
|
;; which are finished (-).
|
|
;; See ediff-redraw-directory-group-buffer for an example.
|
|
;; In all likelihood, ediff-redraw-directory-group-buffer can be used
|
|
;; directly or after a small modification.
|
|
;; 2. What action to take when the user clicks button 2 or types v,e, or
|
|
;; RET. See ediff-filegroup-action.
|
|
;; 3. Provide a list of pairs or triples of file names (or buffers,
|
|
;; depending on the particular Ediff operation you want to invoke)
|
|
;; in the following format:
|
|
;; (HEADER (nil nil (obj1 nil) (obj2 nil) (obj3 nil))
|
|
;; (...) ...)
|
|
;; The function ediff-make-new-meta-list-element can be used to create
|
|
;; 2nd and subsequent elements of that list (i.e., after the
|
|
;; description header). See ediff-make-new-meta-list-element for the
|
|
;; explanation of the two nil placeholders in such elements.
|
|
;;
|
|
;; There is API for extracting the components of the members of the
|
|
;; above list. Search for `API for ediff-meta-list' for details.
|
|
;;
|
|
;; HEADER must be a list of SIX elements (nil or string):
|
|
;; (regexp metaobj1 metaobj2 metaobj3 merge-save-buffer
|
|
;; comparison-function)
|
|
;; The function ediff-redraw-registry-buffer displays the
|
|
;; 1st - 4th of these in the registry buffer.
|
|
;; For some jobs some of the members of the header might be nil.
|
|
;; The meaning of metaobj1, metaobj2, and metaobj3 depend on the job.
|
|
;; Typically these are directories where the files to be compared are
|
|
;; found.
|
|
;; Also, keep in mind that the function ediff-prepare-meta-buffer
|
|
;; (which see) prepends the session group buffer to the descriptor, so
|
|
;; the descriptor becomes 7-long.
|
|
;; Ediff expects that your function (in 2 above) will arrange to
|
|
;; replace this prepended nil (via setcar) with the actual ediff
|
|
;; control buffer associated with an appropriate Ediff session.
|
|
;; This is arranged through internal startup hooks that can be passed
|
|
;; to any of Ediff major entries (such as ediff-files, epatch, etc.).
|
|
;; See how this is done in ediff-filegroup-action.
|
|
;;
|
|
;; Session descriptions are of the form
|
|
;; (nil nil (obj1 . nil) (obj2 . nil) (obj3 . nil))
|
|
;; which describe the objects relevant to the session.
|
|
;; Use ediff-make-new-meta-list-element to create these things.
|
|
;; Usually obj1/2/3 are names of files, but they may also be other
|
|
;; things for some jobs. For instance, obj3 is nil for jobs that
|
|
;; involve only two files. For patch jobs, obj2 and obj3 are markers
|
|
;; that specify the patch corresponding to the file
|
|
;; (whose name is obj1).
|
|
;; The nil's are placeholders, which are used internally by ediff.
|
|
;; 4. Write a function that makes a call to ediff-prepare-meta-buffer
|
|
;; passing all this info.
|
|
;; You may be able to use ediff-directories-internal as a template.
|
|
;; 5. If you intend to add several related pieces of functionality,
|
|
;; you may want to keep the function in 4 as an internal version
|
|
;; and then write several top-level interactive functions that call it
|
|
;; with different parameters.
|
|
;; See how ediff-directories, ediff-merge-directories, and
|
|
;; ediff-merge-directories-with-ancestor all use
|
|
;; ediff-directories-internal.
|
|
;;
|
|
;; A useful addition here could be session groups selected by patterns
|
|
;; (which are different in each directory). For instance, one may want to
|
|
;; compare files of the form abc{something}.c to files old{something}.d
|
|
;; which may be in the same or different directories. Or, one may want to
|
|
;; compare all files of the form {something} to files of the form {something}~.
|
|
;;
|
|
;; Implementing this requires writing a collating function, which should pair
|
|
;; up appropriate files. It will also require a generalization of the
|
|
;; functions that do the layout of the meta- and differences buffers and of
|
|
;; ediff-filegroup-action.
