* | Various battery.el improvements (bug#41808)Basil L. Contovounesios2020-06-181-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/battery.el: Mention BSD support in Commentary. Don't load preloaded lisp/emacs-lisp/timer.el. (battery--files): New function. (battery--find-linux-sysfs-batteries): Use it and make fewer syscalls. (battery-status-function): Perform GNU/Linux checks in increasing order of obsolescence: sysfs, ACPI, and then APM. Simplify Darwin check. Add :version tag now that battery-upower is the default. (battery-echo-area-format, battery-mode-line-format): Mention %s. (battery-load-low, battery-load-critical): New faces. (battery-update): Display battery-mode-line-format even if percentage is N/A. Apply faces battery-load-low or battery-load-critical according to the percentage, but append them so they don't override user customizations. Update all mode lines since we are in global-mode-string. (battery-linux-proc-apm-regexp): Mark as obsolete, replacing with... (battery--linux-proc-apm): ...this new rx definition. (battery-linux-proc-apm): Use it. Fix indentation. Simplify. (battery--acpi-rate, battery--acpi-capacity): New rx definitions. (battery-linux-proc-acpi): Use them. Fix pathological whitespace regexps. Simplify. (battery-linux-sysfs): Fix docstring and indentation. Reduce number of file searches. Simplify. (battery-bsd-apm): Fix docstring. Simplify. (battery-pmset): Fix docstring. Simplify ID regexp. * lisp/emacs-lisp/rx.el (rx-define): Indent as a defun. * test/lisp/battery-tests.el (battery-linux-proc-apm-regexp): Test new battery--linux-proc-apm rx definition. (battery-acpi-rate-regexp, battery-acpi-capacity-regexp): New tests.
* Fix rx error with ? and ??Mattias Engdegård2020-03-051-1/+1
| | | | | | | | | The ? and ?? rx operators are special in that they can be written as characters (space and '?' respectively). This confused the definition look-up mechanism in rare cases. * lisp/emacs-lisp/rx.el (rx--expand-def): Don't look up non-symbols. * test/lisp/emacs-lisp/rx-tests.el (rx-charset-or): Test.

* rx: Improve 'or' compositionality (bug#37659)Mattias Engdegård2020-03-011-28/+48
| | | | | | | | | | | | | | | | | Perform 'regexp-opt' on nested 'or' forms, and after expansion of user-defined and 'eval' forms. Characters are now turned into strings for wider 'regexp-opt' scope. This preserves the longest-match semantics for string in 'or' forms over composition. * doc/lispref/searching.texi (Rx Constructs): Document. * lisp/emacs-lisp/rx.el (rx--normalise-or-arg) (rx--all-string-or-args): New. (rx--translate-or): Normalise arguments first, and check for strings in subforms. (rx--expand-eval): Extracted from rx--translate-eval. (rx--translate-eval): Call rx--expand-eval. * test/lisp/emacs-lisp/rx-tests.el (rx-or, rx-def-in-or): Add tests. * etc/NEWS: Announce.
* Fix rx charset generationMattias Engdegård2020-02-291-1/+5
| | | | | | * lisp/emacs-lisp/rx.el (rx--charset-p): Don't overquote. (rx--generate-alt): Generate '.' for negated newline. * test/lisp/emacs-lisp/rx-tests.el (rx-any, rx-charset-or): Test.
* rx: Use longest match for all-string 'or' forms (bug#37659)Mattias Engdegård2020-02-121-1/+1
| | | | | | | | | | | | | | | | | Revert to the Emacs 26 semantics that always gave the longest match for rx 'or' forms with only string arguments. This guarantee was never well documented, but it is useful and people likely have come to rely on it. For example, prior to this change, (rx (or ">" ">=")) matched ">" even if the text contained ">=". * lisp/emacs-lisp/rx.el (rx--translate-or): Don't tell regexp-opt to preserve the matching order. * doc/lispref/searching.texi (Rx Constructs): Document the longest-match guarantee for all-string 'or' forms. * test/lisp/emacs-lisp/rx-tests.el (rx-or): Update test.

* Allow characters and single-char strings in rx charsetsMattias Engdegård2019-12-131-6/+20
| | | | | | | | | | | | | | | | 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 Engdegård2019-12-121-15/+26
| | | | | | | | | | | | | | 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 Engdegård2019-12-101-95/+214
| | | | | | | | | | | | | | | | | | | | | | 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'.

* Don't use the return value of 'push'Mattias Engdegård2019-12-041-1/+1
| | | | | | | Although 'push' returns the modified list, it isn't actually documented to do so, so don't rely on it. * lisp/emacs-lisp/rx.el (rx--translate-any): Add progn.
* 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.

* Use [^z-a] for matching any character (anychar/anything) in rxMattias Engdegård2019-10-181-1/+1
| | | | | | | | | | * 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).

(rx--subforms): New helper function for handling subforms, including non-constant case. (rx-group-if, rx-and, rx-or, rx-=, rx->=, rx-repeat, rx-submatch) (rx-submatch-n, rx-kleene, rx-atomic-p): Use it to handle non-constant subforms.

* rx: fix `or' ordering by adding argument to regexp-optMattias Engdegård2019-03-021-1/+1
| | | | | | | | | | | | | | | | | The rx `or' form may reorder its arguments in an unpredictable way, contrary to user expectation, since it sometimes uses `regexp-opt'. Add a NOREORDER option to `regexp-opt' for preventing it from producing a reordered regexp (Bug#34641). * doc/lispref/searching.texi (Regular Expression Functions): * etc/NEWS (Lisp Changes in Emacs 27.1): Describe the new regexp-opt NOREORDER argument. * lisp/emacs-lisp/regexp-opt.el (regexp-opt): Add NOREORDER. Make no attempt at regexp improvement if the set of strings contains a prefix of another string. (regexp-opt--contains-prefix): New. * lisp/emacs-lisp/rx.el (rx-or): Call regexp-opt with NOREORDER. * test/lisp/emacs-lisp/rx-tests.el: Test rx `or' form match order.
* Prevent over-eager rx character range condensationMattias Engdegård2019-02-161-0/+7
| | | | | | | | | | | | | `rx' incorrectly considers character ranges between ASCII and raw bytes to cover all codes in-between, which includes all non-ASCII Unicode chars. This causes (any "\000-\377" ?Å) to be simplified to (any "\000-\377"), which is not at all the same thing: [\000-\377] really means [\000-\177\200-\377] (Bug#34492). * lisp/emacs-lisp/rx.el (rx-any-condense-range): Split ranges going from ASCII to raw bytes. * test/lisp/emacs-lisp/rx-tests.el (rx-char-any-raw-byte): Add test case. * etc/NEWS: Mention the overall change (Bug#33205).
