* lisp/char-fold.el (describe-char-fold-equivalences): Improve
docstring. Pass t for 'allow-single' arg in call to
`read-char-by-name' so that single characters can be entered directly.
* lisp/char-fold.el (describe-char-fold-equivalences): Map
`get-char-code-property' across all the component codepoints of the
equivalent character rather than just the first one.
(char-fold--default-override): New defconst with the default value nil.
(char-fold--previous): Add char-fold--default-override.
(char-fold--make-table): Don't populate the table with default chars
when char-fold-override or char-fold--default-override is non-nil.
(char-fold-update-table): Add char-fold--default-override.
* lisp/char-fold.el (char-fold-to-regexp): Don't use regexp-quote
when the length of regexp reaches 5000. (Bug#40216)
* lisp/isearch.el (isearch-search): On big regexp in char-fold mode
gracefully fall back to literal mode, try to search again and display
momentary-message about switching to literal mode.
(isearch--momentary-message): Add optional arg SECONDS.
* lisp/char-fold.el (char-fold--default-include)
(char-fold--default-exclude): Add some default values.
* test/lisp/char-fold-tests.el (char-fold--test-without-customization)
(char-fold--test-with-customization): Move some test data to
default values. Add more data for tests to pass. (Bug#35689)
* doc/emacs/search.texi (Lax Search): Document
char-fold-symmetric, char-fold-include, char-fold-exclude.
* lisp/char-fold.el (char-fold--default-include)
(char-fold--default-exclude, char-fold--default-symmetric)
(char-fold--previous): New defconsts.
(char-fold-include, char-fold-exclude, char-fold-symmetric):
New defcustoms.
(char-fold-make-table): Use them.
(char-fold-update-table): New function called at top-level.
* test/lisp/char-fold-tests.el (char-fold--test-no-match-exactly)
(char-fold--permutation): New functions.
(char-fold--test-without-customization)
(char-fold--test-with-customization): New tests.
* lisp/char-fold.el (char-fold-make-table): Decompose the
decomposition of each character, adding equivalences to the original
character, until no more decompositions are left.
* lisp/isearch.el (isearch-search-fun-default): Move possible autoload
trigger outside let-binding of search-spaces-regexp.
* lisp/char-fold.el (char-fold-make-table): Remove no longer needed
workaround.
* lisp/info.el (Info-search-whitespace-regexp):
* lisp/isearch.el (search-whitespace-regexp):
* src/search.c (syms_of_search) <search-spaces-regexp>: Add warning
about adding capturing groups to the value.
* test/lisp/char-fold-tests.el: Remove, binding search-spaces-regexp
to a different should be considered a bug.
with body extracted from INITVALUE of defconst (bug#35689).
Bind search-spaces-regexp to nil (bug#35802).
* test/lisp/char-fold-tests.el: Relocate helpers to file beginning.
(char-fold--test-bug-35802): New test.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
This is in preparation for using Gnulib regex for etags,
to avoid collisions in include directives.
* src/regex-emacs.c: Rename from src/regex.c.
* src/regex-emacs.h: Rename from src/regex.h. All uses changed.
* test/src/regex-emacs-tests.el: Rename from test/src/regex-tests.el.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
