| | | | | | | | | | | | | | * lisp/emacs-lisp/subr-x.el (string-limit): Return more correct results in the CODING-SYSTEM case for coding systems with BOM and charset designations (bug#48324). Also amend the algorithm to return complete glyphs, not just complete code points.

* | (oclosure-test-limits): Fix test failure when interpretedStefan Monnier2022-06-261-0/+1
| | | | | | | | | | * test/lisp/emacs-lisp/oclosure-tests.el (oclosure-test-limits): Make sure we bind `byte-compile-debug` dynamically.
* | Fix cl-generic bootstrap problemsLars Ingebrigtsen2022-06-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/sqlite-mode.el (require): * lisp/net/eudc.el (require): * lisp/arc-mode.el (require): Require subr-x, since these files are using macros from there. * lisp/emacs-lisp/subr-x.el (with-memoization): Move from here... * lisp/subr.el (with-memoization): ... to here, as it's used from the preloaded cl-generic.el file. * lisp/emacs-lisp/cl-generic.el (cl--generic-compiler): Don't use the autoloaded `byte-compile' function during bootstrap. (cl--generic-get-dispatcher): Don't require subr-x, either. cl-generic has been preloaded since 2015, and most usages of it (in preloaded files) work fine. In particular, using `cl-defgeneric' is unproblematic. However, `cl-defmethod' would end up pulling in the byte compiler (at load time), which would make it impossible to use `cl-defmethod' in pre-loaded files, and this change fixes that (but possibly not in the most self-evidently correct way).
* | bindat (strz): Null terminate fixed-length strings if there is roomRichard Hansen2022-06-221-6/+6
| | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/bindat.el (bindat--pack-strz): For fixed-length strz fields, explicitly write a null terminator after the packed string if there is room (bug#56048). * doc/lispref/processes.texi (Bindat Types): Update documentation. * test/lisp/emacs-lisp/bindat-tests.el (bindat-test--str-strz-prealloc): Update tests.
* | Document and test 'no-byte-compile' behavior.Philipp Stephani2022-06-212-0/+8

* | Fix edebug parsing of .,Lars Ingebrigtsen2022-06-191-0/+9
| | | | | | | | | | * lisp/emacs-lisp/edebug.el (edebug-next-token-class): Parse ., correctly (bug#37653).
* | Slightly faster hash-table-keys and hash-table-valuesMattias Engdegård2022-06-171-0/+7
| | | | | | | | | | | | | | * lisp/emacs-lisp/subr-x.el (hash-table-keys, hash-table-values): Omit the reversal of the returned list. It is not ordered anyway. * test/lisp/emacs-lisp/subr-x-tests.el (subr-x--hash-table-keys-and-values): New test.
* | Warn about misplaced or duplicated function/macro declarationsMattias Engdegård2022-06-172-0/+329
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Doc strings, `declare` and `interactive` forms must appear in that order and at most once each. Complain if they don't, instead of silently ignoring the problem (bug#55905). * lisp/emacs-lisp/byte-run.el (byte-run--parse-body) (byte-run--parse-declarations): New. (defmacro, defun): Check for declaration well-formedness as described above. Clarify doc strings. Refactor some common code. * test/lisp/emacs-lisp/bytecomp-resources/fun-attr-warn.el: * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-fun-attr-warn): New test.
* | bindat (strz): Write null terminator after variable length stringRichard Hansen2022-06-161-2/+2
| | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/bindat.el (bindat--pack-strz): Explicitly write a null byte after packing a variable-length string to ensure proper termination when packing to a pre-allocated string. * doc/lispref/processes.texi (Bindat Types): Update documentation. * test/lisp/emacs-lisp/bindat-tests.el (bindat-test--str-strz-prealloc): Update tests.
* | Normalise setq during macro-expansionMattias Engdegård2022-06-143-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Early normalisation of setq during macroexpand-all allows later stages, cconv, byte-opt and codegen, to be simplified and duplicated checks to be eliminated. * lisp/emacs-lisp/macroexp.el (macroexp--expand-all): Normalise all setq forms to a sequence of (setq VAR EXPR). Emit warnings if necessary. * lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyze-form): * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): * lisp/emacs-lisp/bytecomp.el (byte-compile-setq): Simplify. * test/lisp/emacs-lisp/bytecomp-tests.el: Adapt and add tests. * test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-nonvariable.el; * test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-odd.el: New files.
* | bindat (strz): Error on null byte if packing variable-length stringRichard Hansen2022-06-131-1/+6
| | | | | | | | | | | | * lisp/emacs-lisp/bindat.el (strz): Signal an error if a null byte is encountered while packing a string to a variable-length strz field. * test/lisp/emacs-lisp/bindat-tests.el (strz): Add tests (bug#55938).
* | bindat (str, strz): Reject non-ASCII, non-`eight-bit' charactersRichard Hansen2022-06-121-0/+16
| | | | | | | | | | | | | | | | * lisp/emacs-lisp/bindat.el (str) (strz): Signal an error if the user attempts to pack a multibyte string containing characters other than ASCII and `eight-bit' characters (bug#55897). * doc/lispref/processes.texi (Bindat Types): Update documentation. * test/lisp/emacs-lisp/bindat-tests.el (str) (strz): Add tests.

* | Preserve doc string in `byte-compile` (bug#55830)Mattias Engdegård2022-06-081-0/+21
| | | | | | | | | | | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile--reify-function): Don't transpose doc string and interactive spec, which must come in this order. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-function-attributes): New test.
* | find-func.el: Fix bug#41104Stefan Monnier2022-06-071-0/+7
| | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/find-func.el (find-function-advised-original): Look at the actual function definition rather than `advice--symbol-function` which sometimes returns only the advice. * test/lisp/emacs-lisp/find-func-tests.el (find-func-tests--find-library-verbose): Add test.
* | Test warning suppressions with lexical bindingMattias Engdegård2022-06-061-6/+14
| | | | | | | | | | | | | | | | | | * test/lisp/emacs-lisp/bytecomp-tests.el (test-byte-comp-compile-and-load): Add lexical cookie to file being compiled as part of the test. (bytecomp-test--with-suppressed-warnings): Comment out the test for suppressing warnings when attempting to let-bind `nil`, as that (1) doesn't work and (2) is a silly thing to do anyway.
* | bindat (strz): Fix wrong-type-argument error when unpackingRichard Hansen2022-06-011-1/+0
| | | | | | | | | | | | | | * lisp/emacs-lisp/bindat.el (strz): Fix (wrong-type-argument number-or-marker-p nil) error when unpacking a strz with unspecified (variable) length. * test/lisp/emacs-lisp/bindat-tests.el (strz): Mark test as passing.
* | bindat (strz): Fix off-by-one bug in computed lengthRichard Hansen2022-06-011-2/+0

| | | | | | | | | | * lisp/emacs-lisp/pp.el (pp--insert-lisp): Fix printing of cons cells (bug#55478).
* | Warn about quoted symbols in defcustom choice/other formsLars Ingebrigtsen2022-05-111-0/+6
| | | | | | | | | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile--suspicious-defcustom-choice): New function (bug#16271). (byte-compile-nogroup-warn): Use it to warn about forms like (choice (const :tag "foo" 'bar)).
* | Move buffer-local-set-state to subr because it's used at runtimeLars Ingebrigtsen2022-05-061-12/+0
| | | | | | | | | | | | * lisp/subr.el (buffer-local-set-state) (buffer-local-set-state--get, buffer-local-restore-state): Moved from easy-mmode.el because they have to be available run-time.
* | Add new helper macros for minor modes to restore variablesLars Ingebrigtsen2022-05-061-1/+11
| | | | | | | | | | | | | | | | | | | | | | * doc/lispref/modes.texi (Defining Minor Modes): Document it. * lisp/emacs-lisp/easy-mmode.el (buffer-local-set-state): New macro. (buffer-local-set-state--get): Helper function. (buffer-local-restore-state): New function. * lisp/textmodes/word-wrap-mode.el (word-wrap-whitespace-mode): Use it to simplify code.

* | nadvice.el: Use OClosuresStefan Monnier2022-04-261-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/nadvice.el (advice): New OClosure type. (advice--how-alist): Make it hold prototype OClosures rather than bytecode strings. (advice--bytecodes): Delete var. (advice--where): Make it an obsolete alias of new `advice--how`. (oclosure-interactive-form, cl-print-object) <advice>: New methods. (advice--make-1): Delete function. (advice--make): Use `advice-copy` and `advice-cons`. (advice--tweak): Use `advice-cons`. (add-function, advice-add): Rename `where` arg to `how`. * lisp/emacs-lisp/cl-print.el (cl-print-object) <:extra "nadvice">: Remove now-redundant ad-hoc method. * test/lisp/emacs-lisp/nadvice-tests.el (advice-test-print): New test.
* | Pretty print OClosure slot accessorsStefan Monnier2022-04-261-4/+4
| | | | | | | | | | | | | | * lisp/emacs-lisp/oclosure.el (oclosure--accessor-cl-print): New function. * lisp/emacs-lisp/cl-print.el (cl-print-object) <accessor>: New method. * test/lisp/emacs-lisp/nadvice-tests.el (advice-test-call-interactively): Avoid `defun` within a function.
* | New generic function `oclosure-interactive-form`Stefan Monnier2022-04-261-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's used by `interactive-form` when it encounters an OClosure. This lets one compute the `interactive-form` of OClosures dynamically by adding appropriate methods. This does not include support for `command-modes` for Oclosures. * lisp/simple.el (oclosure-interactive-form): New generic function. * src/data.c (Finteractive_form): Delegate to `oclosure-interactive-form` if the arg is an OClosure. (syms_of_data): New symbol `Qoclosure_interactive_form`. * src/eval.c (Fcommandp): Delegate to `interactive-form` if the arg is an OClosure. * src/lisp.h (VALID_DOCSTRING_P): New function, extracted from `store_function_docstring`. * src/doc.c (store_function_docstring): Use it. * lisp/kmacro.el (kmacro): Don't carry any interactive form. (oclosure-interactive-form) <kmacro>: New method, instead. * test/lisp/emacs-lisp/oclosure-tests.el (oclosure-interactive-form) <oclosure-test>: New method. (oclosure-test-interactive-form): New test. * doc/lispref/commands.texi (Using Interactive): Document `oclosure-interactive-form`.
* | OClosure: New function `function-documentation`Stefan Monnier2022-04-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As mentioned in the original OClosure commit, OClosures (ab)use the bytecode's docstring slot to hold the OClosure's type. This currently prevents OClosures from having their own docstring. Introduce a new generic function `function-documentation` to fetch the docstring of a function, which can then be implemented in various different ways depending on the OClosure's type. * lisp/simple.el (function-documentation): New generic function. (bad-package-check): Strength-reduce `eval` to `symbol-value`. * src/doc.c (Fdocumentation): Use it. * lisp/emacs-lisp/oclosure.el (oclosure--accessor-docstring): New function. * test/lisp/emacs-lisp/oclosure-tests.el (oclosure-test): Add test for accessor's docstrings.
* | OClosure: add support for `slot-value`Stefan Monnier2022-04-041-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/oclosure.el (oclosure--slot-index) (oclosure--slot-value, oclosure--set-slot-value): New functions. * lisp/emacs-lisp/eieio-core.el (eieio-oset, eieio-oref): Consolidate the type test. Use `oclosure--(set-)slot-value`. (eieio--validate-slot-value, eieio--validate-class-slot-value): Don't presume `class` is an EIEIO class. (eieio--class): Fix bogus `:type` info. (eieio--object-class): Simplify. (eieio--known-slot-name-p): New function. (eieio-oref, eieio-oref-default, eieio-oset-default): Use it. * test/lisp/emacs-lisp/oclosure-tests.el: Require `eieio`. (oclosure-test): Make `name` field mutable. (oclosure-test-slot-value): New test.
* | OClosure: Add support for defmethod dispatchStefan Monnier2022-04-011-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/oclosure.el (oclosure--class): Add slot `allparents`. (oclosure--class-make): Add corresponding arg `allparents`. (oclosure, oclosure--build-class): Pass the new arg to the constructor. (oclosure--define): Make the predicate function understand subtyping. * lisp/emacs-lisp/cl-preloaded.el (cl--class-allparents): Move from `cl-generic.el`. * lisp/emacs-lisp/cl-generic.el (cl--generic-class-parents): Move to `cl-preloaded.el` and rename to `cl--class-allparents`. Adjust all callers. (cl--generic-oclosure-tag, cl-generic--oclosure-specializers): New functions. (cl-generic-generalizers) <oclosure-struct>: New generalizer. * test/lisp/emacs-lisp/oclosure-tests.el (oclosure-test-gen): New generic function. (oclosure-test): Add test for dispatch on oclosure types.
* | Add OClosures, a cross between functions and structsStefan Monnier2022-03-281-0/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We here just add the new type. It is not fully self-contained. It requires cooperation from `cconv.el` on the one hand, and it hijacks the docstring info to hold the type of OClosure objects. This does imply that OClosures can't have docstrings, tho this limitation will be lifted in subsequent patches. * lisp/emacs-lisp/oclosure.el: New file. * test/lisp/emacs-lisp/oclosure-tests.el: New file. * doc/lispref/functions.texi (OClosures): New section. * src/eval.c (Ffunction): Accept symbols instead of strings for docstrings. * src/doc.c (store_function_docstring): Avoid overwriting an OClosure type. * lisp/emacs-lisp/cconv.el (cconv--convert-function): Tweak ordering of captured variables. (cconv-convert): Add case for `oclosure--fix-type`.
* | Make `?' work again in read-multiple-choiceLars Ingebrigtsen2022-03-171-2/+1
| | | | | | | | | | * lisp/emacs-lisp/rmc.el (read-multiple-choice): Make the `?' key work again to show the help text.
* | Format long help texts better in read-multiple-choiceFelician Nemeth2022-03-171-1/+23
| | | | | | | | | | * lisp/emacs-lisp/rmc.el (rmc--show-help): Format long help texts better (bug#54430).
* | Make Edebug specification for 'cl-defstruct' more lenient.Philipp Stephani2022-03-141-0/+18
| | | | | | | | | | | | | | | | | | For example, 'xref-item' uses the list form of ':noinline'. * lisp/emacs-lisp/cl-macs.el (cl-defstruct): Accept ':noinline' and ':named' with an argument. * test/lisp/emacs-lisp/cl-macs-tests.el (cl-defstruct/edebug): New unit test.
* | Fix EMBA failure for ert-test-record-backtraceLars Ingebrigtsen2022-03-121-2/+5
| | | | | | | | | | * test/lisp/emacs-lisp/ert-tests.el (ert-test-record-backtrace): Make this work with AOT.
