* lisp/emacs-lisp/edebug.el (edebug-print-length)
(edebug-print-level): Fix customization type to allow setting
the documented valid value nil via the Customize interface.
This improves on the recent fix for master failing to build
on FreeBSD. Suggested by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2018-01/msg00600.html
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Put tempfile next to the target file, as was the original intent.
(cherry picked from commit 64c8467386)
* lisp/emacs-lisp/pcase.el (pcase-dolist, pcase-let)
(pcase-let*): Improve the doc strings.
* doc/lispref/sequences.texi (Sequence Functions): Improve
wording and rename arguments of seq-let to be more
descriptive. Add a cross-reference to "Destructuring with
pcase Patterns".
* doc/lispref/control.texi (Pattern-Matching Conditional):
Improve wording and the menu.
(pcase Macro): Incorporate patch suggested by Paul Eggert
<eggert@cs.ucla.edu>. Reformat text.
(Destructuring with pcase Patterns): Rename from
"Destructuring patterns", and improve wording and indexing.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
Make handling of hash tables and vectors recursive. This is
necessary because the write process, in `eieio-override-prin1' is
also recursive. With any luck, this will be the last fix of its
kind. If that's true, cherry-pick to Emacs 26.2 later on.
Packages which are not directly user-installed shouldn't be autoremoved,
since they can be setup through a different path (via
`package-directory-list') where we have no authority over.
* lisp/emacs-lisp/package.el (package--user-installed-p): New
function.
(package--removable-packages): Use it.
* lisp/emacs-lisp/map-ynp.el (read-answer-short): New defcustom.
(read-answer): New function.
* lisp/subr.el (assoc-delete-all): New function.
* etc/NEWS: Announce them.
* lisp/dired.el (dired-delete-file): Use read-answer.
(dired--yes-no-all-quit-help): Remove function.
(dired-delete-help): Remove defconst.
(backported from master, "New function read-answer (bug#30073)" and
"Respect non-saved value of `read-short-answer' (Bug#31782)")
* lisp/emacs-lisp/lisp-mode.el (indent-sexp): Only signal error if the
initial forward-sexp fails. Suppress scan-error forn any of the
forward-sexp calls after that.
* test/lisp/emacs-lisp/lisp-mode-tests.el (indent-sexp-cant-go): New
test.
* lisp/emacs-lisp/lisp-mode.el (indent-sexp): Look for a sexp that
ends after the current line.
* test/lisp/emacs-lisp/lisp-mode-tests.el (indent-sexp-go): New test.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode): Clear
the buffer-list inside MODE-enable-in-buffers to avoid enabling the
mode recursively. (Bug#31793)
This is partial revert of "Remove ignored argument from
lisp-indent-line", because `indent-line-to' doesn't respect field
boundaries.
* lisp/emacs-lisp/lisp-mode.el (lisp-indent-line): Use delete-region
and indent-to instead of `indent-line-to'.
* test/lisp/emacs-lisp/lisp-mode-tests.el
(lisp-indent-with-read-only-field): Expect to pass.
Don't merge to master, we will fix indent-line-to there instead.
* src/eval.c (call_debugger): Increase the amount of extra Lisp
evaluation depth given to the debugger to allow it to call cl-print.
* lisp/emacs-lisp/debug.el (debugger-setup-buffer): Add a comment
to suggest updating call_debugger when changing print-level.
* lisp/emacs-lisp/package.el (package--download-one-archive): Use
`read' instead of `read-from-string'; the latter always returns a
cons, so the `listp' check on its return value doesn't make sense. It
was changed from `read' to `read-from-string' in 2015-04-01 "*
emacs-lisp/package.el: Implement asynchronous refreshing", but that
change was not needed because `read' works fine on strings as well as
buffers.
* lisp/emacs-lisp/cl.el (labels): Apply the equivalent of the
cl-labels change from 2015-01-16 "* lisp/emacs-lisp/cl-macs.el: Fix
last change".
* test/lisp/emacs-lisp/cl-tests.el (labels-function-quoting): New
test.
* lisp/emacs-lisp/cl-macs.el (cl-flet, cl-labels): Improve docstring,
link to relevant manual page.
* doc/misc/cl.texi (Function Bindings): Don't imply that function
cells of symbols are modified by cl-flet. Don't claim that cl-flet or
cl-labels affect references of the form (quote FUNC).
Backport from master.
Do not use the symbol ‘default’ as a special marker.
Instead, use a value that cannot appear in the program,
improving on a patch proposed by Robert Cochran (Bug#31718#14).
* lisp/emacs-lisp/bytecomp.el (byte-compile--default-val):
New constant.
(byte-compile-cond-jump-table-info)
(byte-compile-cond-jump-table): Use it instead of 'default.
* test/lisp/emacs-lisp/bytecomp-tests.el:
(byte-opt-testsuite-arith-data): Add a test for the bug.
* lisp/emacs-lisp/cl-print.el (cl-print--depth): New variable.
(cl-print-object) <cons>: Print ellipsis if printing depth greater
than 'print-level' or length of list greater than 'print-length'.
(cl-print-object) <vector>: Truncate printing with ellipsis if
vector is longer than 'print-length'.
(cl-print-object) <cl-structure-object>: Truncate printing with
ellipsis if structure has more slots than 'print-length'.
(cl-print-object) <:around>: Bind 'cl-print--depth'.
* test/lisp/emacs-lisp/cl-print-tests.el
(cl-print-tests-3, cl-print-tests-4): New tests.
(cherry picked from commit 0f48d18fd2)
* lisp/emacs-lisp/cl-print.el (cl-print-object) <cons>: Push each
element of list being printed onto cl-print--currently-printing.
* test/lisp/emacs-lisp/cl-print-tests.el (cl-print-circle-2): New
test.
(cherry picked from commit b8aa7ecf54)
Suggested by Drew Adams (Bug#31311).
* lisp/emacs-lisp/pcase.el (pcase): Use EXPVAL in
docstring to stand for the result of evaluating EXP.
(pcase-defmacro): Add (fn ...) form in docstring
that includes [DOC], and the EXPVAL convention.
* lisp/emacs-lisp/pcase.el (pcase--make-docstring):
Split extensions display into two phases, collection
and display, separated by a reordering step that
ensures backquote is the first.
* doc/lispref/control.texi (Pattern matching case statement):
* lisp/emacs-lisp/pcase.el (pcase): State that pcase returns nil if no
patterns match.
(pcase-exhaustive): State that an error is signaled if no patterns
match.
For the following release it is planned to make `if-let*' and
`when-let*' aliases for `if-let' and `when-let'. For now we revert
declaring `if-let' and `when-let' obsolete and tweak the docstrings.
* lisp/emacs-lisp/subr-x.el (if-let*, when-let*): Make docstrings
refer to those of `if-let' and `when-let'.
(if-let, when-let): De-obsolete. Rewrite documentation.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
`object-write' may quote lists inside hash tables and vectors, so
unquote those lists here.
This patch allows the eieio-persistent write/restore process to
perform a clean round trip. It only handles a very specific and
limited range of object structures, but at least the write and read
procedures match.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
The function `eieio-persistent-slot-type-is-class-p' could return
either a single class, or a list of classes.
