| * Revert "Signal error for symbol names with strange quotes (Bug#2967)"Noam Postavsky2018-01-281-17/+0
| | | | | | | | | | | | | | | | | | | | That commit did not make the corresponding change to printing, thus breaking the (eq (read (prin1-to-string SYM)) SYM) invariant for those symbols. It's too late in the release cycle to change printing behavior, therefore revert the reader change. Don't merge to master, the print function will be updated there (see "Fix round tripping of read->print for symbols with strange quotes").

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-2/+2
| | | | | | | | | | | | | 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.
* Signal error for symbol names with strange quotes (Bug#2967)Noam Postavsky2017-07-221-0/+17
| | | | | | | | * src/lread.c (read1): Signal an error when a symbol starts with a non-escaped quote-like character. * test/src/lread-tests.el (lread-tests--funny-quote-symbols): New test. * etc/NEWS: Announce change.
* Fix core dump in substitute-object-in-subtreePaul Eggert2017-07-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a) would dump core, since the C code would recurse indefinitely through the infinite structure. This patch adds an argument to the function, and renames it to lread--substitute-object-in-subtree as the function is not general-purpose and should not be relied on by outside code. See Bug#23660. * src/intervals.c (traverse_intervals_noorder): ARG is now void *, not Lisp_Object, so that callers need not cons unnecessarily. All callers changed. Also, remove related #if-0 code that was “temporary” in the early 1990s and has not been compilable for some time. * src/lread.c (struct subst): New type, for substitution closure data. (seen_list): Remove this static var, as this info is now part of struct subst. All uses removed. (Flread__substitute_object_in_subtree): Rename from Fsubstitute_object_in_subtree, and give it a 3rd arg so that it doesn’t dump core when called from the top level with an already-cyclic structure. All callers changed. (SUBSTITUTE): Remove. All callers expanded and then simplified. (substitute_object_recurse): Take a single argument SUBST rather than a pair OBJECT and PLACEHOLDER, so that its address can be passed around as part of a closure; this avoids the need for an AUTO_CONS call. All callers changed. If the COMPLETED component is t, treat every subobject as potentially circular. (substitute_in_interval): Take a struct subst * rather than a Lisp_Object, for the closure data. All callers changed. * test/src/lread-tests.el (lread-lread--substitute-object-in-subtree): New test, to check that the core dump does not reoccur.

| | | | | | | | | | | | | * src/lread.c (load_warn_old_style_backquotes, Fload, read1) (syms_of_lread): Rename `old-style-backquotes' to `lread--old-style-backquotes', and clarify that it's for internal use only. * lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Rename variable. * test/src/lread-tests.el (lread-tests--old-style-backquotes): Add unit test. * emacs-lisp/bytecomp-tests.el (bytecomp-tests--old-style-backquotes): Add unit test.

* Tweak a recent testTino Calancha2017-05-101-7/+8
| | | | | | | This test fails in my local machine because the data files are compiled, and the test doesn't expect that. * test/src/lread-tests.el (lread-test-bug26837): Match a suffix ending with '.elc' when the data files are compiled.
* Put re-loaded file back at start of load-history (bug#26837)Glenn Morris2017-05-091-0/+13
| | | | | | | | | * src/lread.c (readevalloop): Fix the "whole buffer" check to operate in the correct buffer. (Feval_buffer): Move point back to the start after checking for lexical binding. * test/src/lread-tests.el (lread-test-bug26837): New test. * test/data/somelib.el, test/data/somelib2.el: New test data files.
* Warn about missing backslashes during loadPhilipp Stephani2017-05-011-0/+26
| | | | | | | | | | | | | | | | * src/lread.c (load_warn_unescaped_character_literals, Fload, read1) (syms_of_lread): Warn if unescaped character literals are found (Bug#20152). * lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Check for unescaped character literals during byte compilation. * test/src/lread-tests.el (lread-tests--unescaped-char-literals): New unit test. (lread-tests--with-temp-file, lread-tests--last-message): Helper functions for unit test. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--unescaped-char-literals): New unit test. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--with-temp-file): Helper macro for unit test.

* Treat incomplete integer literals as errorsPhilipp Stephani2016-12-231-0/+8
| | | | | | | | See Bug#25120. * src/lread.c (read_integer): Treat incomplete integer literals as errors. * test/src/lread-tests.el (lread-empty-int-literal): New unit test for incomplete integer literals.
* New function ‘char-from-name’Paul Eggert2016-04-251-4/+44
| | | | | | | | | | | | | | | | | | This also fixes the mishandling of "\N{CJK COMPATIBILITY IDEOGRAPH-F900}", "\N{VARIATION SELECTOR-1}", etc. Problem reported by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2016-04/msg00614.html * doc/lispref/nonascii.texi (Character Codes), etc/NEWS: Document this. * lisp/international/mule-cmds.el (char-from-name): New function. (read-char-by-name): Use it. Document that "BED" is treated as a name, not as a hexadecimal number. Reject out-of-range integers, floating-point numbers, and strings with trailing junk. * src/lread.c (character_name_to_code): Call char-from-name instead of inspecting ucs-names directly, so that we handle computed names like "VARIATION SELECTOR-1". Do not use an auto string, since char-from-name might GC. * test/src/lread-tests.el: Add tests for new behavior, and fix some old tests that were wrong.
* Improve character name escapesPaul Eggert2016-04-211-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | * doc/lispref/nonascii.texi (Character Properties): Avoid duplication of Unicode names. Reformat examples to fit in narrow pages. * doc/lispref/objects.texi (General Escape Syntax): Simplify and better-organize explanation of \N{...} escapes. * src/character.h (CHAR_SURROGATE_PAIR_P): Remove; unused. (char_surrogate_p): New inline function. * src/lread.c: Do not include string.h; no longer needed. (invalid_character_name, check_scalar_value): Remove; the ideas behind these functions are now bundled into character_name_to_code. (character_name_to_code): Remove undocumented support for "CJK IDEOGRAPH-XXXX" names, as "U+XXXX" suffices. Reject monstrosities like "\N{U+-0}" and null bytes in \N escapes. Reject floating point in \N escapes instead of returning garbage. Use AUTO_STRING_WITH_LEN to lessen pressure on the garbage collector. * test/src/lread-tests.el (lread-char-number, lread-char-name) (lread-string-char-number, lread-string-char-name): Test runtime behavior, not compile-time, as the test framework is not set up to test compile-time. (lread-char-surrogate-1, lread-char-surrogate-2) (lread-char-surrogate-3, lread-char-surrogate-4) (lread-string-char-number-2, lread-string-char-number-3): New tests. (lread-string-char-number-1): Rename from lread-string-char-number.

| | | | | | | | | | * lread.c (invalid_character_name, check_scalar_value) (parse_code_after_prefix, character_name_to_code): New helper functions that use 'ucs-names' and parsing for CJK ideographs. (read_escape): Use helper functions. (syms_of_lread): New symbol 'ucs-names'. * test/src/lread-tests.el: New tests; fix a couple of bugs in existing tests.
* Implement named character escapes, similar to PerlPhilipp Stephani2016-04-211-0/+54
* lread.c (init_character_names): New function. (read_escape): Read Perl-style named character escape sequences. (syms_of_lread): Initialize new variable 'character_names'. * test/src/lread-tests.el (lread-char-empty-name): Add test file for src/lread.c.
