* Improving portability. It is no longer assumed that pointersKaz Kylheku2009-11-231-3/+7
| | | | | | | | can be converted to a type long and vice versa. The configure script tries to detect the appropriate type to use. Also, some run-time checking is performed in the streams module to detect which conversions specifier strings to use for printing numbers.
* Introducing symbol packages. Internal symbols are now inKaz Kylheku2009-11-211-4/+11
| | | | | | | | | | a system package instead of being hacked with the $ prefix. Keyword symbols are provided. In the matcher, evaluation is tightened up. Keywords, nil and t are not bindeable, and errors are thrown if attempts are made to bind them. Destructuring in dest_bind is strict in the number of items. String streams are exploited to print bindings to objects that are not strings or characters. Numerous bugfixes.
* Changing ``obj_t *'' occurences to a ``val'' typedef. (Ideally,Kaz Kylheku2009-11-201-4/+4
| | | | | we wouldn't have to declare object variables at all, so why use an obtuse syntax to do so?)

* More removal of C99 wide character I/O, and tightening upKaz Kylheku2009-11-171-3/+3

* Big round of changes to switch the code base to use the streamKaz Kylheku2009-11-161-45/+47
| | | | | | | | | | | | | | | | | abstraction instead of directly using C standard I/O, to eliminate most uses of C formatted I/O, and fix numerous bugs, such variadic argument lists which lack a terminating ``nao'' sentinel. Bug 28033 is addressed by this patch, since streams no longer provide printf-compatible formatting. The native formatter is extended with some additional capabilities to take over. The work on literal objects is expanded and they are now used throughout the code base. Fixed bad realloc in string output stream: reallocating by number of wide chars rather than bytes.
* Previous commit broke UTF-8 lexing, by changing the get_charKaz Kylheku2009-11-131-2/+2
| | | | | | | | semantics on the input stream to wide character input. Also, reading a query the command line (-c) must read bytes from a UTF-8 encoding of the string. We introduce a new get_byte function which can extract bytes from streams which provide it.
* Continuing wchar_t conversion. Making sure all stdio callsKaz Kylheku2009-11-121-41/+41
| | | | | use wide character functions so that there is no illicit mixing. (But the goal is to replace this usage with txr streams).
* Documenting extended characters in man page.Kaz Kylheku2009-11-121-0/+15
| | | | Cleaned up some more issues related to extended characters.
* Big conversion to wide characters and UTF-8 support.Kaz Kylheku2009-11-111-34/+50
| | | | | | | | | 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.
