* | Simplify an example in the modules manualPhilipp Stephani2019-12-261-2/+1
| | | | | | | | | | | | * doc/lispref/internals.texi (Module Misc): Simplify example for how to call 'intern'. There's no need to pass the optional argument explicitly.
* | Promote function type aliases to the public module API.Philipp Stephani2019-12-261-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously module authors had to define type aliases for module functions and finalizers themselves. This commit adds and documents aliases so that this is no longer necessary. * src/emacs-module.h.in: Add 'emacs_function' and 'emacs_finalizer' type aliases. * src/emacs-module.c: Remove old 'emacs_subr' and 'emacs_finalizer' type aliases. (struct Lisp_Module_Function, module_make_function): Switch from 'emacs_subr' to 'emacs_function'. * doc/lispref/internals.texi (Module Functions): Document and use 'emacs_function' type alias. (Module Values): Document 'emacs_finalizer' type alias. * etc/NEWS: Mention change.

* | Make argument names in module interface more consistent.Philipp Stephani2019-12-231-48/+49
|/ | | | | | | | | | | | | | | | | | | | | | | | Previously, the names of arguments and other details were needlessly inconsistent between the documentation, the declarations, and the definitions, as well as between each other. This commit makes them more consistent, in most cases by applying the names from the documentation everywhere. * src/module-env-27.h: * src/module-env-25.h: * src/emacs-module.h.in: * src/emacs-module.c (module_get_environment) (module_make_global_ref, module_free_global_ref) (module_non_local_exit_get, module_non_local_exit_signal) (module_make_function, module_funcall, module_type_of) (module_is_not_nil, module_extract_integer) (module_extract_float, module_copy_string_contents) (module_make_string, module_vec_set, module_vec_get) (module_vec_size, module_extract_time) (module_assert_runtime): * doc/lispref/internals.texi (Module Initialization) (Module Functions, Module Values): Make argument names and some other details consistent. No functional changes.
* Document and verify that emacs_limb_t doesn’t have padding bits.Philipp Stephani2019-12-231-3/+4
| | | | | | | | | | | | | | | | | | This is a useful property when doing further bit-twiddling with the magnitude array before/after calling extract_big_integer or make_big_integer. For example, constructing an emacs_limb_t object using repeated shift-and-add should work as expected, but relies on the type not having padding bits. Since the C standard already guarantees that unsigned integers use a pure binary representation, not having padding bits is enough to guarantee that the type has unique object representations in the sense of C++’s std::has_unique_object_representations. * doc/lispref/internals.texi (Module Values): Document that emacs_limb_t doesn’t have padding bits. * src/emacs-module.c: Verify that emacs_limb_t doesn’t have padding bits.

* Allow characters and single-char strings in rx charsetsMattias Engdegård2019-12-131-5/+6
| | | | | | | | | | | | | | | | The `not' and `intersection' forms, and `or' inside these forms, now accept characters and single-character strings as arguments.

* Change module interface to no longer use GMP objects directly.Philipp Stephani2019-12-041-60/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in the new comment added to emacs-module.c, using GMP directly in the module interface has significant downsides: it couples the module interface directly to the implementation and requires module authors to link their module against the same GMP library as Emacs itself, which is often difficult and an unnecessary burden. By picking a representation for the magnitude that often matches the one used by GMP, we can avoid overhead when converting from and to GMP in most cases. Loading the test module in test/data/emacs-module and evaluating (dotimes (_ 10000) (mod-test-double (* 2 most-negative-fixnum))) under Callgrind shows that on my (GNU/Linux) machine Emacs only spends 10% of the CPU time of mod-test-double in mpz_import and mpz_export combined, even though that function does little else. (By contrast, 30% is spent in allocate_pseudovector.) * src/emacs-module.h.in: Don't check EMACS_MODULE_GMP. Don't include gmp.h. Remove emacs_mpz structure. Instead, define type alias emacs_limb_t and macro EMACS_LIMB_MAX. * src/module-env-27.h: Change interface of extract_big_integer and make_big_integer to take a sign-magnitude representation instead of mpz_t. * src/emacs-module.c: Don't check EMACS_MODULE_GMP or EMACS_MODULE_HAVE_MPZ_T. Add a comment about the chosen implementation. (module_extract_big_integer, module_make_big_integer): Reimplement without using mpz_t in the interface. * doc/lispref/internals.texi (Module Values): Adapt function documentation and example. Stop mentioning GMP and EMACS_MODULE_GMP. * test/data/emacs-module/mod-test.c: Don't define EMACS_MODULE_GMP or EMACS_MODULE_HAVE_MPZ_T. (memory_full, extract_big_integer, make_big_integer): New helper functions, identical to example in the Info documentation. (Fmod_test_nanoseconds, Fmod_test_double): Adapt to new interface.

* Conditionally omit edition numbers, dates in docPaul Eggert2019-11-121-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | This redoes the 2019-11-02T00:24:02!eggert@cs.ucla.edu patch, updated after consultation with John Sullivan. Omit printed edition numbers in online manuals while keeping them in printed manuals. In online manuals the edition numbers seem to cause more confusion than they cure; e.g., https://shop.fsf.org/books/gnu-emacs-manual-18th-edition-v-261 currently advertises "18th edition" even as it points to https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf which says "Seventeenth Edition". It is simpler and less confusing to stick to one version number like "27.0" in online manuals. For printed manuals people can run, e.g., "texi2any -D 'EDITION Nineteenth'" when generating the 19th printed edition of the Emacs manual. * doc/emacs/emacs.texi (EDITION): * doc/lispintro/emacs-lisp-intro.texi (edition-number, update-date): * doc/lispref/elisp.texi (VERSION, DATE): Remove definitions. Instead, let the person printing the book specify these values, with the default being the online version which does not have printed edition numbers. * doc/lispintro/emacs-lisp-intro.texi (titlepage-edition-number): New flag, for the edition number as it appears on the title page.

* Document Lisp floats a bit betterPaul Eggert2019-11-101-2/+6
| | | | | | | | | | | | | * doc/lispref/numbers.texi (Float Basics): * doc/misc/cl.texi (Implementation Parameters): * lisp/emacs-lisp/cl-lib.el (cl-most-positive-float) (cl-least-positive-float) (cl-least-positive-normalized-float, cl-float-epsilon) (cl-float-negative-epsilon): Document IEEE floating point better. Don’t suggest that Emacs might use some floating-point format other than IEEE format, as Emacs currently assumes IEEE in several places and there seems little point in removing those assumptions.
* Move read-char-from-minibuffer from simple.el to subr.el and document it.Juri Linkov2019-11-101-0/+12
| | | | | | | | | | | | * doc/lispref/minibuf.texi (Multiple Queries): Document read-char-from-minibuffer (bug#10477, bug#38076). * lisp/subr.el (read-char-history) (read-char-from-minibuffer-map) (read-char-from-minibuffer-map-hash) (read-char-from-minibuffer-insert-char) (read-char-from-minibuffer-insert-other, empty-history) (read-char-from-minibuffer): Move from simple.el to subr.el.
* 'y-or-n-p' now uses the minibuffer to read 'y' or 'n' answer (bug#38076)Juri Linkov2019-11-101-21/+15
| | | | | | | | | | | | * doc/lispref/minibuf.texi (Yes-or-No Queries): Update the fact that y-or-n-p uses the minibuffer. * lisp/subr.el (y-or-n-p-history-variable): New variable. (y-or-n-p-map): New keymap. (y-or-n-p-insert-y, y-or-n-p-insert-n, y-or-n-p-insert-other): New commands. (y-or-n-p): Rewrite to use read-from-minibuffer and make-composed-keymap with y-or-n-p-map and query-replace-map.
