* 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.
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.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Don't create
the temporary file under temporary-file-directory if the file
being compiled is specified by an absolute file name. This avoids
problems with ACL copying from temporary-file-directory on
FreeBSD. For the details, see
http://lists.gnu.org/archive/html/emacs-devel/2018-01/msg00513.html.
* lisp/emacs-lisp/shadow.el (load-path-shadows-find): Check for
shadowing with case-insensitive matching for files of case-insensitive
directories (as determined by `file-name-case-insensitive-p').
* test/lisp/emacs-lisp/shadow-tests.el: New test.
* test/lisp/emacs-lisp/shadow-resources/p1/foo.el:
* test/lisp/emacs-lisp/shadow-resources/p2/FOO.el: New test files.
The problem was a parse-partial-sexp call which tried to use the STOPBEFORE
argument to detect non-syntactic WS. This fails on a "}", which does not
begin a sexp.
* lisp/emacs-lisp/lisp.h (beginning-of-defun--in-emptyish-line-p): Enhance to
handle BOL being in a string.
(beginning-of-defun-comments): Call the above function in place of the call
to parse-partial-sexp.
(run-mode-hooks): `funcall` the functions instead of `eval`ing the forms.
* lisp/emacs-lisp/derived.el (define-derived-mode): Push functions
rather than forms (bug#29679).
The changes to cl argument parsing are not backwards compatible, and
cause inconvenience when writing macros (e.g., instead of doing '&aux
,@auxargs', some more complicated conditionals would be required).
The `cl-defstruct' macro makes use of this convenience when defining
empty structs (Bug#29728).
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
(cl--do-&aux, cl--do-arglist): Undo strict checking of &rest, &key,
and &aux.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs-bad-arglist): Remove
test.
