* rx: Improve 'or' compositionality (bug#37659)Mattias Engdegård2020-03-01
| | | | | | | | | | | | | | | | | 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.

* Remove the optional KEEP-ORDER argument to regexp-optMattias Engdegård2020-02-13
| | | | | | | | | | | | | This argument was added for the 'or' clause in rx, but it turned out to be a bad idea (bug#37659), and there seems to be little other use for it. * lisp/emacs-lisp/regexp-opt.el (regexp-opt): Remove KEEP-ORDER. * doc/lispref/searching.texi (Regexp Functions): * etc/NEWS: Remove it from the documentation. * test/lisp/emacs-lisp/regexp-opt-tests.el (regexp-opt-test--match-all) (regexp-opt-test--check-perm, regexp-opt-test--explain-perm) (regexp-opt-keep-order, regexp-opt-longest-match): Simplify test.
* rx: Use longest match for all-string 'or' forms (bug#37659)Mattias Engdegård2020-02-12
| | | | | | | | | | | | | | | | | 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.
* Update copyright year to 2020Paul Eggert2020-01-01

* More precise 'regexp-opt' documentationMattias Engdegård2019-12-18
| | | | | | | | * lisp/emacs-lisp/regexp-opt.el (regexp-opt): * doc/lispref/searching.texi (Regexp Functions): Be more specific about how the KEEP-ORDER argument actually works. If nil, the regexp guarantees a longest match; this is the behaviour that many callers implicitly rely on.
* Allow characters and single-char strings in rx charsetsMattias Engdegård2019-12-13
| | | | | | | | | | | | | | | | 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 Engdegård2019-12-12

* Add `union' and `intersection' to rx (bug#37849)Mattias Engdegård2019-12-10
| | | | | | | | | | | | | | | | | | | | | | 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.
