* lisp/emacs-lisp/checkdoc.el (checkdoc-error): When
`checkdoc-diagnostic-buffer' is set to "*warn*", print the warning
to the standard output.
(bug#20754)
* lisp/calc/calc-misc.el (calc-help): Fix quoting.
The strings in question are not doc strings, so this partially
undoes the recent change that assumed they were doc strings.
* lisp/cedet/srecode/srt-mode.el (srecode-macro-help):
* lisp/info.el (Info-finder-find-node):
Use curved quotes.
* lisp/emacs-lisp/derived.el (derived-mode-make-docstring):
Also allow curved quotes in doc strings.
* lisp/emacs-lisp/map.el (map-let): New macro.
(map--make-pcase-bindings, map--make-pcase-patterns): New functions.
* test/automated/map-tests.el: New test for `map-let'.
(package-menu--post-refresh): Call `tabulated-list-print' with the
UPDATE argument. This only affects the refresh action, the revert
action still erases tags.
(package-menu-get-status): Change `assq' to `assoc'.
(package-menu--mark-upgrades-1): New function.
(package-menu--mark-upgrades-pending): New variable.
(package-menu-mark-upgrades): Use them to delay marking until
after refresh is done.
(package-menu--post-refresh): Call mark-upgrades-1 if
mark-upgrades-pending is non-nil.
(tabulated-list-print): New optional argument, UPDATE. If
non-nil, the list is printed by only adding and deleting the
changed entries, instead of erasing the whole buffer. This method
is much faster when few or no entries have changed.
* doc/lispref/modes.texi (Tabulated List Mode): Document it.
* etc/NEWS: Document it.
* lisp/frame.el (gui-method--name, gui-method, gui-method-define)
(gui-method-declare, gui-call): Remove.
(frame-creation-function): Use cl-defgeneric.
(make-frame): Adjust callers.
* lisp/menu-bar.el (menu-bar-edit-menu):
Use gui-backend-selection-exists-p.
* lisp/select.el (x-get-clipboard): Use gui-backend-get-selection.
(gui-backend-get-selection): New cl-generic to replace
gui-get-selection method.
(gui-backend-set-selection): New cl-generic to replace
gui-set-selection method.
(gui-selection-owner-p): New cl-generic to replace
gui-selection-owner-p method.
(gui-backend-selection-exists-p): New cl-generic to replace
gui-selection-exists-p method. Adjust all callers.
* lisp/server.el (server-create-window-system-frame): Don't ignore
window-system spec even when unsupported.
* lisp/simple.el (deactivate-mark): Use new gui-backend-* functions.
* lisp/startup.el (handle-args-function, window-system-initialization):
Use cl-defgeneric.
(command-line): Adjust calls accordingly.
* lisp/term/ns-win.el (ns-window-system-initialization): Turn into
a window-system-initialization method.
(handle-args-function, frame-creation-function): Use cl-defmethod.
(gui-set-selection, gui-selection-owner-p, gui-selection-exists-p)
(gui-get-selection): Use cl-defmethod on the new functions instead.
* lisp/term/pc-win.el (w16-get-selection-value): Turn into
a gui-backend-get-selection method.
(gui-selection-exists-p, gui-selection-owner-p, gui-set-selection):
Use cl-defmethod on the new functions instead.
(msdos-window-system-initialization): Turn into
a window-system-initialization method.
(frame-creation-function, handle-args-function): Use cl-defmethod.
* lisp/term/w32-win.el (w32-window-system-initialization): Turn into
a window-system-initialization method.
(handle-args-function, frame-creation-function): Use cl-defmethod.
(gui-set-selection, gui-selection-owner-p, gui-selection-exists-p)
(gui-get-selection): Use cl-defmethod on the new functions instead.
* lisp/term/x-win.el (x-window-system-initialization): Turn into
a window-system-initialization method.
(handle-args-function, frame-creation-function): Use cl-defmethod.
(gui-set-selection, gui-selection-owner-p, gui-selection-exists-p)
(gui-get-selection): Use cl-defmethod on the new functions instead.
* lisp/term/xterm.el (xterm--set-selection): Turn into
a gui-backend-set-selection method.
* src/nsselect.m (Fns_selection_exists_p): Remove unused arg `terminal'.
(Fns_selection_owner_p): Remove unused arg `terminal'.
(Fns_get_selection): Remove unused args `time_stamp' and `terminal'.
(package--update-selected-packages): New function.
(package-menu-execute): Use it before starting the transaction,
this way the list of selected packages is updated even when the
transaction fails.
(package-menu--perform-transaction): Don't edit selected-packages.
* lisp/emacs-lisp/cl-generic.el (cl-generic-define): Don't throw away
previously defined methods.
(cl-generic-define-method): Let-bind purify-flag instead of using `fset'.
(cl--generic-prefill-dispatchers): Only define during compilation.
(cl-method-qualifiers): Remove redundant alias.
(help-fns-short-filename): Silence byte-compiler.
* test/automated/cl-generic-tests.el: Adjust to new defgeneric semantics.
(package-menu--partition-transaction): New function.
(package-menu--prompt-transaction-p, package-menu-execute): Use
it.
(package-menu--perform-transaction): Don't do any messaging.
* lisp/subr.el (let-when-compile): New let-like macro that makes its
bindings known to macros like `eval-when-compile' in the body.
* lisp/emacs-lisp/lisp-mode.el: Change the top-level `pcase-let' to a
`let-when-compile'. Also comment out the unused lexical var
`el-kws-re'.
The change greatly improves readability, while providing almost the
same (even shorter) byte code: instead of pre-evaluating 10 variables,
tossing them into a list, and destructuring that list a full screen
page later, the variables are simply bound as they are evaluated,
wrapped individually in `eval-when-compile'.
(package--used-elsewhere-p): New optional arg, ALL, and return
package-desc objects instead of names.
(package-delete): Update accordingly.
(describe-package-1): Describe which packages require the package.
* lisp/emacs-lisp/checkdoc.el (checkdoc-error): When `noninteractive'
is non-nil, echo the error with `warn'.
How it can be used in -batch:
(with-current-buffer (find-file "checkdoc.el")
(checkdoc-current-buffer t))
Since a map is not a data structure but a concept, adding information
about the possible types of maps can be useful information.
* lisp/emacs-lisp/map.el: Add documentation about the type of MAP to
each public function.
(tabulated-list-init-header): Document new behavior.
(tabulated-list-print-fake-header): No nothing if
`tabulated-list--header-string' is nil.
(tabulated-list--header-string): Add a docstring.
* doc/lispref/modes.texi (Tabulated List Mode): Document it.
* etc/NEWS: Document it.
