2010-08-08remove "discouraged" infrastructureAndy Wingo1-2/+12
* libguile/discouraged.h: Remove. * libguile/deprecated.c (scm_internal_select, scm_thread_sleep) (scm_thread_usleep): Deprecate formerly discouraged names. * libguile/eq.h (SCM_EQ_P): * libguile/pairs.h (SCM_NULLP, SCM_NNULLP, SCM_CONSP, SCM_NCONSP): * libguile/boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP, SCM_BOOL): (SCM_NEGATE_BOOL, SCM_BOOL_NOT): Undiscourage these names, because I'm not sure deprecating them will do any good. * libguile.h: * libguile/gen-scmconfig.c: * libguile/numbers.c: * libguile/init.c: * libguile/Makefile.am: * configure.ac: Remove bits that referenced discouraged.h, and dealt with the "discouraging" system.
2010-04-09change remaining %nil -> #nilAndy Wingo1-3/+4
* doc/ref/vm.texi: * libguile/boolean.h: * libguile/pairs.h: * module/language/elisp/README: * test-suite/tests/elisp-compiler.test: * test-suite/tests/load.test: Change remaining mentions of %nil to #nil.
2010-04-09lisp nil always enabledAndy Wingo1-15/+3
* configure.ac: Remove --disable-elisp option. Lisp nil is always enabled. * libguile/boolean.h: * libguile/gen-scmconfig.c: * libguile/gen-scmconfig.h.in: * libguile/init.c: * libguile/lang.c: * libguile/lang.h: * libguile/pairs.h: * libguile/private-options.h: * libguile/read.c: Remove conditionals for disabling elisp.
2010-03-30nil is false, wheeAndy Wingo1-5/+6
* libguile/boolean.h (scm_is_false): Recognize nil as false, by default. (scm_is_bool): Recognize nil as a boolean. * libguile/boolean.c (scm_not, scm_boolean, scm_to_bool, scm_is_bool): Adapt to treat nil as false. * libguile/vm-i-system.c (br-if, br-if-not): Just use scm_is_false instead of specifically mentioning nil.
2010-03-28Renumber IFLAGSs so the first 8 are reserved for lisp booleans.Mark H Weaver1-1/+1
This enables more efficient implementations of several operations, e.g. scm_is_lisp_bool, canonicalize_boolean, fast_boolean_not, converting SCM booleans to C booleans, etc. * libguile/tags.h: Renumber IFLAGs. * libguile/print.c: Renumber iflagnames to match. * libguile/boolean.c: * libguile/boolean.h: SCM_XXX_ANOTHER_BOOLEAN_DONT_USE --> SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_0
2010-01-19Reinstate `scm_is_bool ()' as a function.Ludovic Courtès1-1/+3
* libguile/boolean.c (scm_is_bool): New function. * libguile/boolean.h (scm_is_bool): New function declaration.
2009-10-27the cube of lisp booleans (#f nil () #t)Mark H Weaver1-4/+85
* Renumbers the IFLAG constants. * Adds several macros related to boolean type tests, null tests, and boolean-truth testing (including lisp-style boolean-truth tests). * Adds compile-time checks to verify the necessary IFLAG numbering properties needed for the checks to work properly. * Changes some existing code to use the new optimized macros, without changing the semantics of the code at all (except that scm_is_bool is changed from a function to a macro). I added the following macros, whose names explicitly state how %nil should be handled. See the comments in the patch for more information about these. scm_is_false_assume_not_lisp_nil scm_is_true_assume_not_lisp_nil scm_is_false_and_not_lisp_nil scm_is_true_or_lisp_nil scm_is_false_or_lisp_nil scm_is_true_and_not_lisp_nil scm_is_lisp_false scm_is_lisp_true scm_is_null_assume_not_lisp_nil scm_is_null_and_not_lisp_nil scm_is_null_or_lisp_nil scm_is_bool_and_not_lisp_nil scm_is_bool_or_lisp_nil The following already-existing macros are defined as aliases, such that their semantics is unchanged (although scm_is_bool used to be a function and is now a macro). scm_is_null --> scm_is_null_and_not_lisp_nil scm_is_false --> scm_is_false_and_not_lisp_nil scm_is_true --> scm_is_true_or_lisp_nil scm_is_bool --> scm_is_bool_and_not_lisp_nil (I still believe that these should be changed to versions that handle %nil properly, but await approval on that point, so these patches do not make those changes) Also, if the preprocessor macro SCM_ENABLE_ELISP is not true (this macro already existed and was used in lang.h), all overheads associated with %nil handling are eliminated from the above macros. * libguile/tags.h (SCM_BOOL_F, SCM_BOOL_T, SCM_UNSPECIFIED) (SCM_UNDEFINED, SCM_UNBOUND, SCM_ELISP_NIL): Renumber, so that a number of important distinctions (false versus true, end-of-list, etc) can be made by masking a single bit. Also define a number of build-time tests to assert that this condition holds. * libguile/boolean.h (scm_is_false_and_not_nil, scm_is_true_or_nil) (scm_is_false_assume_not_nil, scm_is_true_assume_not_nil): (scm_is_false_or_nil, scm_is_true_and_not_nil) (scm_is_bool_or_nil, scm_is_bool_and_not_nil): New exciting macros to test certain boolean/end-of-list properties. (scm_is_false, scm_is_true): Use a restrictive definition, where only SCM_BOOL_F is false. Should probably change in the future. (scm_is_bool): Incompatible change: changed to be a macro. Was a function before. Probably should allow nil as a boolean, but that will be for a later patch. (scm_is_lisp_false, scm_is_lisp_true): New macros, implementing the standard Lisp boolean predicates, where '() is actually false. * libguile/eval.i.c (CEVAL): Fix a number of false-or-nil and similar tests to use the new macros. * libguile/lang.h (SCM_NULL_OR_NIL_P): Use scm_is_null_or_nil. * libguile/pairs.c: Add a compile-time check that null and nil differ by only one bit. * libguile/pairs.h (scm_is_null_and_not_nil, scm_is_null_assume_not_nil) (scm_is_null_or_nil): New exciting macros! (scm_is_null): Just be scm_is_null_and_not_nil, for now. * libguile/print.c: Adapt to the reordering, and print suitably nasty things for the not-to-be-used values.

name for a Scheme object (now a void*), and SCM as 32 bit word for storing tags and immediates (now a long int). Introduced SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious code in the process: arbiter.c (use macros), unif.c (scm_array_p),

1996-09-04Don't install the unwashed masses of Guile header files in theJim Blandy1-1/+1
main #include path; put most of them in a subdirectory called 'libguile'. This avoids naming conflicts between Guile header files and system header files (of which there were a few). * Makefile.in (pkgincludedir): Deleted. (innerincludedir): New variable; this and $(includedir) are enough. (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..". (installed_h_files): Divide this up. Now this variable lists those header files which should go into $(includedir) (i.e. appear directly in the #include path), and ... (inner_h_files): ... this new variable says which files appear in a subdirectory, and are referred to as <libguile/mumble.h>. (h_files): List them both. (install): Create innerincludedir, not pkgincludedir. Put the installed_h_files and inner_h_files in their proper places.
