Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
Add an option ediff-show-ancestor', to control if the ancestor buffer
must be shown in 3way merges (Bug#25493); set it non-nil by default.
Add a toggle to change this option interactively; the original
value of the option is restored on exit.
Update the window setup so that the ancestor buffer is
shown in 3way merges when ediff-show-ancestor is non-nil.
Any operation on ediff windows must take in account the
ancestor window as well, when this is shown.
* lisp/vc/ediff-init.el (ediff-show-ancestor): New option.
(ediff--show-ancestor-orig): New defvar.
* lisp/vc/ediff-wind.el (ediff-window-Ancestor): New defvar.
(ediff-setup-windows-plain-merge, ediff-setup-windows-multiframe-merge):
Display ancestor buffer if ediff-show-ancestor is non-nil.
(ediff-keep-window-config): Expect ancestor window in
ediff-window-config-saved.
(ediff-window-alist): Add entry for the ancestor window.
* lisp/vc/ediff-util.el (ediff-setup-control-buffer):
ediff-window-config-saved contains ancestor window.
(ediff-show-ancestor): Delete this command.
(ediff-setup-keymap): Bind ediff-toggle-show-ancestor to '/' for merge jobs.
(ediff-update-diffs): Compute new diffs using ancestor buffer in 3way merges;
don't cheat it to think that is performing a comparison, that trick is not
necessary anymore: simply call 'ediff-setup-diff-regions-function'
with file-A, file-B and the file ancestor.
(ediff-recenter): Update doc string. Consider the ancestor buffer.
(ediff--check-ancestor-exists): New defun.
(ediff-toggle-show-ancestor): New command; toggle ediff-show-ancestor.
(ediff--restore-options-on-exit): Restore ediff-show-ancestor on exit.
(ediff-scroll-vertically, ediff-scroll-horizontally)
(ediff-operate-on-windows): Consider the ancestor as well.
* lisp/vc/ediff-help.el (ediff-long-help-message-merge):
List ediff-toggle-show-ancestor.
* doc/misc/ediff.texi (Introduction, Quick Help Commands): Update manual.
; * etc/NEWS: Announce these changes.
* lisp/vc/ediff-init.el (ediff-current-diff-Ancestor)
(ediff-fine-diff-Ancestor): Use defaults consistent with
faces for 'ediff-buffer-A' and 'ediff-buffer-B'.
Problem reported by Artur Malabarba in:
http://lists.gnu.org/archive/html/emacs-devel/2015-11/msg01513.html
Most of these fixes are to documentation; many involve fixing
longstanding quoting glitches that are independent of the
recent substitute-command-keys changes. The changes to code are:
* lisp/cedet/mode-local.el (mode-local-augment-function-help)
(describe-mode-local-overload):
Substitute docstrings before displaying them.
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
Quote the generated docstring for later substitution.
This patch should not change behavior. It typically omits backslashes
where they are redundant (e.g., in the string literal "^\$").
In a few places, insert backslashes where they make regular
expressions clearer: e.g., replace "^\*" (equivalent to "^*") with
"^\\*", which has the same effect as a regular expression.
Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs,
and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with
RCS IDs, as that makes it clearer that the backslash is intended.
* lisp/fringe.el (fringe-bitmap-p): Make it a plain function.
* lisp/tooltip.el (tooltip-region-active-p): Remove.
* lisp/net/shr.el (shr-char-breakable-p, shr-char-kinsoku-bol-p)
(shr-char-kinsoku-eol-p, shr-char-nospace-p): Use define-inline.
* lisp/url/url-future.el (url-future-done-p, url-future-completed-p)
(url-future-errored-p, url-future-cancelled-p):
* lisp/url/url-dav.el (url-dav-http-success-p): Use define-inline.
* lisp/vc/ediff-init.el (ediff-odd-p): Remove.
(ediff-background-face): Use cl-oddp instead.
(ediff-buffer-live-p): Make it a defsubst.
Use nil rather than `default' for the "default" appearance.
* lisp/vc/ediff-util.el (ediff-inferior-compare-regions)
(ediff-toggle-autorefine, ediff-unselect-difference): Don't use
a misleading `default' value when it's really a boolean.
* lisp/vc/ediff-init.el (ediff-set-overlay-face): Don't set help-echo if the
overlay is not visible.
Fixes: debbugs:17388
* lisp/vc/diff-mode.el (diff-header, diff-file-header): Remove "green"
to avoid confusion with `diff-added' that now uses green colors.
(diff-removed): Use shades of red.
(diff-added): Use shades of green.
(diff-changed): Leave just the yellow color.
(diff-use-changed-face): New variable.
(diff-font-lock-keywords): Use `diff-use-changed-face' to decide
how to highlight context diff changes.
(diff-refine-change): Use shades of yellow.
(diff-refine-removed): New face that uses shades of red.
(diff-refine-added): New face that uses shades of green.
(diff-refine-hunk): Use `diff-refine-change', `diff-refine-added',
`diff-refine-removed' in the call to `smerge-refine-subst'
depending on the value of `diff-use-changed-face'.
* lisp/vc/ediff-init.el (ediff-current-diff-A, ediff-fine-diff-A):
Add face condition `min-colors 88' with shades of red.
(ediff-current-diff-B, ediff-fine-diff-B): Add face condition
`min-colors 88' with shades of green.
(ediff-current-diff-C, ediff-fine-diff-C): Add face condition
`min-colors 88' with shades of yellow.
* lisp/vc/smerge-mode.el (smerge-mine): Use shades of red.
(smerge-other): Use shades of green.
(smerge-base): Use shades of yellow.
(smerge-refined-change): Empty face.
(smerge-refined-removed): New face that uses shades of red.
(smerge-refined-added): New face that uses shades of green.
(smerge-refine-subst): Rename arg `props' to `props-c'. Add new
args `props-r' and `props-a', and use them. Doc fix.
(smerge-refine): Evaluate `smerge-use-changed-face' and depending
on its value use different faces `smerge-refined-change',
`smerge-refined-removed', `smerge-refined-added' in the call to
`smerge-refine-subst'.
* vc/ediff-init.el: Always define ediff-pixel-width/height.
* vc/ediff-wind.el (ediff-setup-windows-default): New function.
(ediff-window-setup-function): Use it as the default, to set up
windows based on whether the current frame is graphical.
(ediff-choose-window-setup-function-automatically): Make obsolete.
Fixes: debbugs:2138
It hasn't worked in a VC sense since 2008-05-02T07:12:59Z!esr@snark.thyrsus.com, though this was
not documented at the time (grr).
* lisp/vc/vc-hooks.el (vc-toggle-read-only): Make it an obsolete alias
for toggle-read-only. Note that this hasn't called vc-next-action
since 2008-05-02, though it wasn't documented at the time.
* lisp/files.el (toggle-read-only): Remove obsolete comment about
version control.
* doc/emacs/buffers.texi (Misc Buffer): Don't mention vc-toggle-read-only.
* lisp/cedet/ede.el (ede-maybe-checkout): Function deleted;
vc-toggle-read-only does not do version control now.
* lisp/cedet/ede/project-am.el (project-remove-file, project-add-file)
(project-new-target): Don't call ede-maybe-checkout.
* lisp/cedet/ede/util.el (ede-make-buffer-writable): Don't use
vc-toggle-read-only.
* lisp/vc/ediff-init.el (ediff-toggle-read-only-function): Use
toggle-read-only.
Tiny change; note that author said he placed it in the public domain.
(If this wasn't a tiny change, we would still need paperwork.)
* lisp/vc/ediff-init.el (ediff-use-faces, ediff-highlight-all-diffs):
Move ediff-defvar-local calls after defcustoms.
