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.
This commit reverts declaring `if-let' and `when-let' obsolete in
favor of the new `if-let*' and `when-let*' versions because of the
compiler warning mess (Bug#30039). Instead we make foo-let* aliases
for foo-let. The old single-tuple variable spec case is still
supported for backward compatibility.
* lisp/emacs-lisp/subr-x.el (if-let, when-let): Don't declare
obsolete. Tweak edebug specs.
(and-let): Renamed from `and-let*' for compatibility with the names
`if-let' and `when-let'.
(if-let*, when-let*, and-let*): Define as aliases for `if-let',
`when-let' and `and-let'.
* test/lisp/emacs-lisp/subr-x-tests.el (if-let-single-tuple-case-test)
(when-let-single-tuple-case-test): New tests for the single-binding
tuple case.
In the whole file, prefer the names without "*".
* doc/lispref/debugging.texi (Profiling): Improve the description
of elp.el. Improve wording of the rest of the section. (Bug#30491)
* lisp/emacs-lisp/elp.el (elp-instrument-list): Make the
interactive invocation work. Doc fix.
