* Allow characters and single-char strings in rx charsetsMattias Engdegård2019-12-131-6/+14
| | | | | | | | | | | | | | | | The `not' and `intersection' forms, and `or' inside these forms, now accept characters and single-character strings as arguments. Previously, they had to be wrapped in `any' forms. This does not add expressive power but is a convenience and is easily understood. * doc/lispref/searching.texi (Rx Constructs): Amend the documentation. * etc/NEWS: Announce the change. * lisp/emacs-lisp/rx.el (rx--charset-p, rx--translate-not) (rx--charset-intervals, rx): Accept characters and 1-char strings in more places. * test/lisp/emacs-lisp/rx-tests.el (rx-not, rx-charset-or) (rx-def-in-charset-or, rx-intersection): Test the change.
* Use `or' instead of `union' for charset union in rxMattias Engdegård2019-12-121-19/+25
| | | | | | | | | | | | | | Design change suggested by Stefan Monnier. * doc/lispref/searching.texi (Rx Constructs): * etc/NEWS: Document. * lisp/emacs-lisp/rx.el (rx--translate-or): Detect charset arguments. (rx--charset-p): New. (rx--translate-not, rx--charset-intervals, rx--translate-union): Change from `union' to `or'. (rx--translate-form, rx--builtin-forms, rx): Remove `union'. * test/lisp/emacs-lisp/rx-tests.el (rx-union, rx-def-in-union) (rx-intersection): Rename tests and change `union' to `or' and `|'.

* Add `union' and `intersection' to rx (bug#37849)Mattias Engdegård2019-12-101-0/+57
| | | | | | | | | | | | | | | | | | | | | | These character set operations, together with `not' for set complement, improve the compositionality of rx, and reduce duplication in complicated cases. Named character classes are not permitted in set operations. * lisp/emacs-lisp/rx.el (rx--translate-any): Split into multiple functions. (rx--foldl, rx--parse-any, rx--generate-alt, rx--intervals-to-alt) (rx--complement-intervals, rx--intersect-intervals) (rx--union-intervals, rx--charset-intervals, rx--charset-union) (rx--charset-all, rx--charset-intersection, rx--translate-union) (rx--translate-intersection): New. (rx--translate-not, rx--translate-form, rx--builtin-forms, rx): Add `union' and `intersection'. * test/lisp/emacs-lisp/rx-tests.el (rx-union ,rx-def-in-union) (rx-intersection, rx-def-in-intersection): New tests. * doc/lispref/searching.texi (Rx Constructs): * etc/NEWS: Document `union' and `intersection'.

* Avoid duplicated character classes in rxMattias Engdegård2019-12-031-1/+3
| | | | | | | | For example, (any digit digit) should produce "[[:digit:]]", not "[[:digit:][:digit:]]". * lisp/emacs-lisp/rx.el (rx--translate-any): Deduplicate character classes. * test/lisp/emacs-lisp/rx-tests.el (rx-any): Add test case.
* Improve errors & warnings due to fancy quoted vars (Bug#32939)Noam Postavsky2019-11-281-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | Add some hints to the message for byte compiler free & unused variable warnings, and 'void-variable' errors where the variable has confusable quote characters in it. * lisp/help.el (uni-confusables), uni-confusables-regexp): New constants. (help-command-error-confusable-suggestions): New function, added to `command-error-function'. (help-uni-confusable-suggestions): New function. * lisp/emacs-lisp/bytecomp.el (byte-compile-variable-ref): * lisp/emacs-lisp/cconv.el (cconv--analyze-use): Use it. * lisp/emacs-lisp/lisp-mode.el (lisp--match-confusable-symbol-character): New function. (lisp-fdefs): Use it to fontify confusable characters with font-lock-warning-face when they occur in symbol names. * doc/lispref/modes.texi (Faces for Font Lock): * doc/lispref/objects.texi (Basic Char Syntax): Recommend backslash escaping of confusable characters, and mention new fontification. * etc/NEWS: Announce the new fontification behavior. * test/lisp/emacs-lisp/lisp-mode-tests.el (lisp-fontify-confusables): New test.
* Refix conditional step clauses in cl-loopdickmao2019-11-221-4/+64
| | | | | | | | | | | | | * lisp/emacs-lisp/cl-macs.el (cl--loop-bindings, cl--loop-symbol-macs, cl-loop): Add cl--loop-conditions, remove cl--loop-guard-cond. (cl--push-clause-loop-body): Apply clause to both cl--loop-conditions and cl--loop-body (cl--parse-loop-clause): Use cl--push-clause-loop-body. * test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs-loop-and-assignment): Use docstring. (cl-macs-loop-for-as-arith): Removed expected failure. (cl-macs-loop-conditional-step-clauses): Add some tests (bug#29799).
* Expand rx definitions inside (not ...)Mattias Engdegård2019-10-271-1/+16
| | | | | | | | | * lisp/emacs-lisp/rx.el (rx--translate-not): * test/lisp/emacs-lisp/rx-tests.el (rx-not, rx-def-in-not): * doc/lispref/searching.texi (Rx Constructs, Extending Rx): Allow user-defined rx constructs to be expanded inside (not ...) forms, for better composability (bug#37849).
* Don't try to add nil packages on refreshStefan Kangas2019-10-212-0/+18
| | | | | | | | | * lisp/emacs-lisp/package.el (package-read-archive-contents): Don't try to add nil entries. Warn instead. (Bug#28502) * test/lisp/emacs-lisp/package-tests.el (package-test-update-archives/ignore-nil-entry): New test. * test/lisp/emacs-lisp/package-resources/with-nil-entry/archive-contents: New file.
* Use [^z-a] for matching any character (anychar/anything) in rxMattias Engdegård2019-10-181-3/+3
| | | | | | | | | | * lisp/emacs-lisp/rx.el (rx--translate-symbol): * test/lisp/emacs-lisp/rx-tests.el (rx-any, rx-atoms): Use [^z-a] instead of ".\\|\n" for anychar. The new expression is faster (about 2×) and does not allocate regexp stack space. For example, (0+ anychar) now matches strings of any size (bug#37659).
* Add `unmatchable' as alias for (or) in rx (bug#37659)Mattias Engdegård2019-10-181-0/+2
| | | | | | | | | * lisp/emacs-lisp/rx.el (rx--translate-symbol, rx--builtin-symbols, rx): * test/lisp/emacs-lisp/rx-tests.el (rx-atoms): * doc/lispref/searching.texi (Rx Constructs): * etc/NEWS: Add `unmatchable', more descriptive than (or), and corresponding to the variable `regexp-unmatchable'.
* Add `anychar' as alias to `anything' in rx (bug#37659)Mattias Engdegård2019-10-181-2/+2
| | | | | | | | | * lisp/emacs-lisp/rx.el (rx--translate-symbol, rx--builtin-symbols, rx): * test/lisp/emacs-lisp/rx-tests.el (rx-atoms): * doc/lispref/searching.texi (Rx Constructs): * etc/NEWS: Add `anychar', an alias for `anything'. Since `anychar' is more descriptive (and slightly shorter), treat it as the preferred name.
* Correctly explain test failures with mixed uni/multibyte stringsMattias Engdegård2019-10-131-0/+23
| | | | | | | | | * lisp/emacs-lisp/ert.el (ert--explain-equal-rec): * test/lisp/emacs-lisp/ert-tests.el (ert-test-explain-equal): When explaining a difference between a unibyte and a multibyte string, first convert both to multibyte. Otherwise, we might end up comparing unibyte char C to multibyte char C, 127<C<256, and not detect the difference (bug#30219).
* * lisp/emacs-lisp/map.el (map-into) <hash-table>: Allow keyword argsAndrea Corallo2019-10-111-1/+4
| | | | | | | | (map--into-hash): New function, extracted from `map-into <hash-table>`. Speed it up a bit by using gethash instead of map-elt when we know we're accessing a hash table. * test/lisp/emacs-lisp/map-tests.el (test-map-into): Add corresponding test.
* Remove two checkdoc tests checked in by mistakeLars Ingebrigtsen2019-10-111-16/+0
| | | | | * test/lisp/emacs-lisp/checkdoc-tests.el: Remove &aux and &context checks mistakenly checked in (as these aren't implemented) (bug#37697).

* Add `rx-submatch-n' for compatibility (bug#37517)Mattias Engdegård2019-09-291-0/+3
| | | | | | | | It was an internal symbol in the old `rx' implementation, used in old versions of the `flycheck' package. * lisp/emacs-lisp/rx.el (rx-submatch-n): Alias of `rx-to-string'. * test/lisp/emacs-lisp/rx-tests.el (rx-compat): Test it.

* | Compile any subsequence of `cond' clauses to switch (bug#36139)Mattias Engdegård2019-06-191-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A single `cond' form can how be compiled to any number of switch ops, optionally interspersed with non-switch conditions. Previously, switch ops would only be used for whole `cond' forms containing no other tests. * lisp/emacs-lisp/bytecomp.el (byte-compile--cond-vars): Rename from `byte-compile-cond-vars'. (byte-compile--default-val): Remove. (byte-compile--cond-switch-prefix): Replace `byte-compile-cond-jump-table-info'; now also returns trailing non-switch clauses. (byte-compile-cond-jump-table): New arguments; no longer compiles the default case. (byte-compile-cond): Look for and compile switches at any place in the list of clauses. * test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data): Add test expression.
* | Compile cond with heterogeneous tests into switch (bug#36139)Mattias Engdegård2019-06-191-1/+24
| | | | | | | | | | | | | | | | | | | | Allow any mixture of `eq', `eql' and `equal', `memq', `memql' and `member' in a switch-like `cond' to be compiled into a single switch. * lisp/emacs-lisp/bytecomp.el (byte-compile--common-test): New. (byte-compile-cond-jump-table-info): Use most specific common test. * test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data): Add test cases for multi-value clause cond forms.
* | Tighter pcase or-pattern member function selection (bug#36139)Mattias Engdegård2019-06-191-2/+4
| | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/pcase.el (pcase--u1): Use the most specific of `memq', `memql' and `member' in or-patterns with constant cases. This improves performance and may help the byte-code compiler generate a switch. * test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-member): Add mixed-type or-pattern test cases.
* | Disable filling of warnings in a bytecomp testGlenn Morris2019-06-161-1/+2
| | | | | | | | | | * test/lisp/emacs-lisp/bytecomp-tests.el (test-suppression): Disable filling rather than working around it.

* | Allow for line breaks in a bytecomp testGlenn Morris2019-06-121-0/+1
| | | | | | | | | | * test/lisp/emacs-lisp/bytecomp-tests.el (test-suppression): Warnings from the byte compiler may be filled.
* | Give more information in a bytecomp test failureGlenn Morris2019-06-121-2/+2
| | | | | | | | | | * test/lisp/emacs-lisp/bytecomp-tests.el (test-suppression): More informative failure messages.
* | Add the new macro with-suppressed-warningsLars Ingebrigtsen2019-06-121-0/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/byte-run.el (with-suppressed-warnings): New macro. * doc/lispref/compile.texi (Compiler Errors): Document with-suppressed-warnings and deemphasise with-no-warnings slightly. * lisp/emacs-lisp/bytecomp.el (byte-compile--suppressed-warnings): New internal variable. (byte-compile-warning-enabled-p): Heed byte-compile--suppressed-warnings, bound via with-suppressed-warnings. (byte-compile-initial-macro-environment): Provide a macro expansion of with-suppressed-warnings. (byte-compile-file-form-with-suppressed-warnings): New byte hunk handler for the suppressed symbol machinery. (byte-compile-suppressed-warnings): Ditto for the byteop.

(byte-compile-form, byte-compile-normal-call) (byte-compile-normal-call, byte-compile-variable-ref) (byte-compile-set-default, byte-compile-variable-set) (byte-compile-function-form, byte-compile-set-default) (byte-compile-warn-obsolete, byte-compile--declare-var): Pass the symbol being warned in to byte-compile-warning-enabled-p. * test/lisp/emacs-lisp/bytecomp-tests.el (test-suppression): New function. (bytecomp-test--with-suppressed-warnings): Tests.
