| | | | | | | | | | | | | | | | | | | | | | (get_filter): Handle (fun ...) syntax. * match.c (v_bind): Establish dynamic environment frame around dest_bind, and stash the bindings there so filters can have access to the bindings.

| | | | in regex module not exposed in header. Etc.
* Renaming global variables that denote symbols, such that theyKaz Kylheku2009-11-241-15/+17
| | | | have a _s suffix.
* Improving portability. It is no longer assumed that pointersKaz Kylheku2009-11-231-0/+1
| | | | | | | | 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.
* * unwind.c (uw_throw): If streams are not initialized,Kaz Kylheku2009-11-201-0/+5
| | | | | | we have an unhandled exception too early in initialization. Use C stream to print an error message and abort. Using the nil stream variable will just cause a recursion bomb.
* Changing ``obj_t *'' occurences to a ``val'' typedef. (Ideally,Kaz Kylheku2009-11-201-23/+23
| | | | | we wouldn't have to declare object variables at all, so why use an obtuse syntax to do so?)
* Big round of changes to switch the code base to use the streamKaz Kylheku2009-11-161-36/+10
| | | | | | | | | | | | | | | | | 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.
* Continuing wchar_t conversion. Making sure all stdio callsKaz Kylheku2009-11-121-2/+2
| | | | | use wide character functions so that there is no illicit mixing. (But the goal is to replace this usage with txr streams).
* Big conversion to wide characters and UTF-8 support.Kaz Kylheku2009-11-111-10/+10
| | | | | | | | | 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.
* Throw exception on stream error during close, or I/O operations. ThisKaz Kylheku2009-11-061-0/+1
| | | | | | is needed for pipes that terminate abnormally or return failed termination. Pipe and stdio streams have an extra description field so they are printed in a readable way.
* Bug ID 27895: Calls to protect have an argument list terminatedKaz Kylheku2009-11-011-1/+1
| | | | by the integer constant 0 rather than a proper null pointer constant.
