* Add clarification to if-let* docstringMark Oteiza2017-09-131-4/+5
| | | | | | Also make its behaviour consistent with and-let* in that empty bindings results in success, not failure. * lisp/emacs-lisp/subr-x.el: Edit docstring, change else to then.
* Remove "baroque" use of prefix argument from gensymMark Oteiza2017-09-131-2/+9
| | | | | | | | | 'cl-gensym' was simply moved here, but let us take an opportunity to shed some historical baggage. * lisp/subr.el (gensym): Remove special treatment of PREFIX as a number. Use "g" as prefix to differentiate from cl-gensym defaults. * doc/lispref/symbols.texi (Creating Symbols): Update accordingly. * lisp/emacs-lisp/cl-macs.el (cl--gensym-counter, cl-gensym): Restore.
* ; Fix previous commitMark Oteiza2017-09-131-6/+2
| | | | | | | Removing extraneous code, thanks to Michael Heerdegen. * lisp/emacs-lisp/subr-x.el (internal--listify): Remove latter condition which always evaluates to t. (internal--build-binding-value-form): Remove dead code.
* Update uses of if-let and when-letMark Oteiza2017-09-121-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | * lisp/dom.el (dom-previous-sibling): * lisp/emacs-lisp/package.el (package--with-work-buffer): (package--sort-deps-in-alist, package--sort-by-dependence): (package-install-from-archive, package-install): (package-menu-execute, package-menu--populate-new-package-list): * lisp/filenotify.el (file-notify--rm-descriptor): (file-notify--event-watched-file, file-notify--event-file-name): (file-notify--event-file1-name, file-notify-rm-watch): (file-notify-valid-p): * lisp/gnus/message.el (message-toggle-image-thumbnails): * lisp/gnus/nnimap.el (nnimap-request-move-article): * lisp/ibuf-ext.el (ibuffer-repair-saved-filters): * lisp/mpc.el (mpc-format): * lisp/net/eww.el (eww-tag-meta, eww-process-text-input): (eww-save-history): * lisp/net/shr.el (shr-tag-base, shr-tag-object, shr-make-table-1): * lisp/progmodes/prog-mode.el (prettify-symbols--post-command-hook): * lisp/svg.el (svg-remove): * lisp/textmodes/css-mode.el (css--named-color): (css--colon-inside-funcall): * lisp/textmodes/sgml-mode.el (html-current-buffer-classes): (html-current-buffer-ids): Use if-let* and when-let* instead.
* Implement and-let*Mark Oteiza2017-09-121-38/+70
| | | | | | | | | | | | | | | | | | | | This also includes changes to if-let and when-let. The single tuple special case is ambiguous, and binding a symbol to nil is not as useful as binding it to its value outside the lexical scope of the binding. (Bug#28254) * etc/NEWS: Mention. * lisp/emacs-lisp/subr-x.el (internal--listify): (internal--build-binding-value-form): Extend to account for solitary symbols and (EXPR) items in binding varlist. (if-let*, when-let*): Nix single tuple case and incumbent bind-symbol-to-nil behavior. (and-let*): New macro. (if-let, when-let): Mark obsolete. Redefine in terms of if-let*, so they implicitly gain the new features without breaking existing code. * test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of single-tuple special case, lack of binding solitary symbols to nil, and the introduction of uninterned symbols for (EXPR) bindings. Add SRFI-2 test suite adapted to Elisp.
* Move gensym to core ElispMark Oteiza2017-09-129-32/+21
| | | | | | | | | | | | | | | | | | | | | * doc/lispref/symbols.texi (Creating Symbols): Mention gensym right after make-symbol. * etc/NEWS: Mention. * lisp/emacs-lisp/cl-macs.el (cl--gensym-counter): Alias to gensym-counter. (cl-gensym): Alias to gensym. * lisp/emacs-lisp/cl.el: Remove gensym from list of aliases. * lisp/emacs-lisp/edebug.el (edebug-make-enter-wrapper): * lisp/emacs-lisp/ert-x.el (ert-with-message-capture): (ert--expand-should-1, ert--expand-should): (ert--should-error-handle-error): * lisp/emacs-lisp/generator.el (cps--gensym): * lisp/emacs-lisp/gv.el (setf): * lisp/emacs-lisp/inline.el (inline--do-letlisteval): * lisp/emacs-lisp/pcase.el (pcase--make-docstring, pcase-dolist): (pcase--funcall, pcase--u1): Use gensym. * lisp/subr.el (gensym-counter): New variable. (gensym): New function, assimilated from cl-lib.
* Fix cl-gentempMark Oteiza2017-09-121-4/+5
| | | | | * lisp/emacs-lisp/cl-macs.el (cl--gentemp-counter): New variable. (cl-gentemp): Use it. Change prefix to "T".

* ; Fix previous commitMark Oteiza2017-09-111-1/+1
| | | | | The printer otherwise includes the 0x prefix. * lisp/emacs-lisp/cl-print.el: Add 0x to format.
* Include sxhash of object with printed bytecodeMark Oteiza2017-09-111-1/+1
| | | | | | | | This printing, while succint, is rather opaque. At least give an immediate clue of whether different byte code printouts are for the same or different byte code objects. * lisp/emacs-lisp/cl-print.el (cl-print-object): Add object sxhash to printed token "#<bytecode>".
* ; * lisp/emacs-lisp/ert.el (ert-batch-backtrace-right-margin): Fix tag.Glenn Morris2017-09-051-1/+1

* Support lazy loading for autogenerated usage docstrings too (Bug#27748)Noam Postavsky2017-08-301-1/+1
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-file-form-defmumble): Consider any documentation that ended up in code as a docstring (e.g., autogenerated (fn ARG1 ARG2) type things), not just what the user passed.
* Drop docstrings from cl-defsubst produced inline bodies (Bug#27748)Noam Postavsky2017-08-301-1/+2
| | | | | * lisp/emacs-lisp/cl-macs.el (cl-defsubst): Use macroexp-parse-progn to drop the docstring. Add a simple docstring to the compiler-macro.
* Minor simplification for byte-compile-constant-pushNoam Postavsky2017-08-291-5/+4
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-constant): Move the meat of the code from here... (byte-compile-constant-push): ... to here. No need to bind byte-compile--for-effect anymore.
* Fix over-protection of byte-compiled filesPaul Eggert2017-08-262-1/+12
| | | | | | | | | | Problem reported by Sven Joachim (Bug#28244). Also, fix similar problem for autoload files. * lisp/emacs-lisp/autoload.el (autoload--save-buffer): Set temp file modes to the buffer-file-name file modes (or 666 if not available) as adjusted by umask. * lisp/emacs-lisp/bytecomp.el (byte-compile-file): Set temp file modes to 666 as adjusted by umask.

* Stop printing '4' in .elc files after 'define-symbol-prop' callsNoam Postavsky2017-08-191-1/+2
| | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-define-symbol-prop): Return nil in case we have compiled the form, to prevent a redundant constant from getting added to the compiled output.

* Don't define gv expanders in compiler's runtime (Bug#27016)Noam Postavsky2017-08-071-6/+1
| | | | | | | | This prevents definitions being compiled from leaking into the current Emacs doing the compilation. * lisp/emacs-lisp/gv.el (gv-define-expander): Use function-put instead of `put' with `eval-and-compile'. * test/lisp/emacs-lisp/gv-tests.el: New tests.
* Let the cl-typep effects of defclass work during compilation (Bug#27718)Noam Postavsky2017-08-071-1/+1
| | | | | | | | | * lisp/emacs-lisp/eieio.el (defclass): Use `define-symbol-prop' instead of `put'. * test/lisp/emacs-lisp/eieio-tests/eieio-tests.el (eieio-tests--dummy-function): Remove. (eieio-test-25-slot-tests, eieio-test-23-inheritance-check): Don't expect to fail if compiled.

(byte-compile-define-symbol-prop): New function, handles compilation of top-level `define-symbol-prop' and `function-put' calls by putting the symbol setting into `overriding-plist-environment'. Co-authored-by: Noam Postavsky <npostavs@gmail.com>
* Don't error on circular values in testcoverNoam Postavsky2017-08-071-2/+8
| | | | | * lisp/emacs-lisp/testcover.el (testcover-after, testcover-1value): Consider circular lists to be non-equal instead of signaling error.
* Catch argument and macroexpansion errors in ertAlexander Gramiak2017-08-071-9/+32
| | | | | | | | | | | | This kludge catches errors caused by evaluating arguments in ert's should, should-not, and should-error macros; it also catches macroexpansion errors inside of the above macros (Bug#24402). * lisp/emacs-lisp/ert.el: (ert--should-signal-hook): New function. (ert--expand-should-1): Catch macroexpansion errors. * test/lisp/emacs-lisp/ert-tests.el (ert-test-should-error-argument) (ert-test-should-error-macroexpansion): Tests for argument and expansion errors.

| | | | | | | | | * lisp/emacs-lisp/autoload.el (autoload--save-buffer): * lisp/emacs-lisp/bytecomp.el (byte-compile-file): Use make-temp-file, not make-temp-name, to avoid an unlikely race that could lose data. Remove the deletion hook as quickly as possible after the file is renamed; though a race still remains here, it is smaller than before.
