* compat: fix glaringly broken init-time handling.Kaz Kylheku2021-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are doing numerous compat_ver checks in various init functions, to enact alternative symbol registrations. Only problem is, compat_ver is always zero during initialization; it is not set until the -C option is processed in txr_main. Registrations must be fixed up after initialization; that's what the compat_fixup mechanism is for. This is an long-standing problem which affects compatibility operation going back over 150 versions. * arith.c (arith_init): Move compat logic to arith_compat_fixup.

The struct type system allows struct types to be defined for symbols like regex or str, which are used by built-in or cobj types. This is a bad thing. What is worse, structure instances are COBJ types which identify their type using the COBJ class symbol mechanism. There are places in the C implementation which assume that when a COBJ has a certain class symbol, it is of a certain expected type, which is totally different from and incompatible form a struct instance. User code can define a structure object which will fool that code. There are multiple things going on in this patch. The major theme is that the COBJ representation is changing. Instead of a class symbol, COBJ instances now carry a "struct cobj_class *" pointer. This pointer is obtained by registration via the cobj_register function. All modules must register their class symbols to obtain these class handles, which are then used in cobj() calls for instantiation. The CPTR type was identical to COBJ until now, except for the type tag. This is changing; CPTR objects will keep the old representation with the class symbol. commit 20fdfc6008297001491308849c17498c006fe7b4 Author: Kaz Kylheku <kaz@kylheku.com> Date: Thu Jul 8 19:17:39 2021 -0700 * ffi.h (carray_cls): Declared. * hash.h (hash_cls): Declared.

* Fix match-regex not conforming to documentation.Kaz Kylheku2016-09-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation says that match-regex returns the length. Actually, it returns the position after the last character matched. This makes a difference when the match doesn't begin at character zero. The actual behavior is that of the match_regex C function which has behaved that way since the dawn of TXR, and internals depend on it behaving that way. So the internal function is being retained, and a new function is being registered as the match-regex intrinsic. The choice of binding for match-regex is subject to the compatibility option. The behavior of match-regst is also being fixed since its return value is incorrect due to this issue. Since its return value makes no sense at all (does not represent the matched text), it is not subject to the compatibility option; it is just fixed to conform with the documentation. * regex.c (match_regex_len): New function. (match_regst): Keep using match_regex, but use its return value properly. This simplifies the range extraction code, which is why match_regex works that way in the first place. (regex_init): Register match-regex to match_regex_len, unless compatibility <= 150 is requested; then register to match_regex. * regex.h (match_regex_len): Declared. * txr.1: Compatibility notes added.

* Regular expression module updated to do unicode character sets.Kaz Kylheku2009-11-121-12/+57
| | | | | | | | | | | Most of the changes are in the area of representing sets. Also, a bug was found in the compilation of regex character sets: ranges straddling two adjacent blocks of 32 characters were not being added to the character set. However, ranges falling within a single 32 block, or spanning three or more such blocks, worked properly. This bug is not tickled by common ranges such as A-Z, or 0-9, which land within a 32 block.
* Big conversion to wide characters and UTF-8 support.Kaz Kylheku2009-11-111-1/+1
| | | | | | | | | This is incomplete. There are too many dependencies on wide character support from the C stream I/O library, and implicit use of some encoding which may not be UTF-8. The regex code does not handle wide characters properly. Character type is still int in some places, rather than wchar_t. Test suite passes though.
