* Allow -c scripts to not have a trailing newline.Kaz Kylheku2009-11-134-7/+37
| | | | | | | | | | | | | Test suite exercises -c now. txr.c (txr_main): If the script specified with -c is not terminated by a newline, just add a newline. On the shell command line, it's a nuisance to have to add the extra line before closing the quote. It's also awkward in scripting, because the shell (or at least Bash 3.0) does not produce a final terminating newline in command substitution syntax like -c "$(cat file)". The last newline in the file is trimmed, and has to be explicitly added in the script itself, which is wrong in the case when the file is empty.
* Previous commit broke UTF-8 lexing, by changing the get_charKaz Kylheku2009-11-135-3/+102
| | | | | | | | 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 Kylheku2009-11-1211-164/+189
| | | | | use wide character functions so that there is no illicit mixing. (But the goal is to replace this usage with txr streams).
* Fixed broken utf8_from.Kaz Kylheku2009-11-123-21/+151
| | | | Added utf8_encode, utf8_decoder_init, utf8_decode.
* Documenting extended characters in man page.Kaz Kylheku2009-11-125-14/+107
| | | | Cleaned up some more issues related to extended characters.

* Regular expression module updated to do unicode character sets.Kaz Kylheku2009-11-123-61/+544
| | | | | | | | | | | 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.
* * txr.c (main): call setlocale to set the LC_CTYPE to en_US.UTF-8,Kaz Kylheku2009-11-112-0/+8
| | | | | so that the C library streams do the encoding. Once the program is weaned from C library wide character stream I/O, this can go away.
* Big conversion to wide characters and UTF-8 support.Kaz Kylheku2009-11-1120-432/+750
| | | | | | | | | 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.
* hash.c (hash_grow): Rewritten to avoid resizing the vectorKaz Kylheku2009-11-102-16/+27
| | | | | | | in place, and thus having to pulling all conses into a big list. TODO: avoid recomputing the hash function over the keys. We could enhance cons cells with two more fields without using additional storage.
* Changing representation of objects to allow for unboxed characters.Kaz Kylheku2009-11-094-46/+64
| | | | | Now numbers and characters fit into a cell. We lose one more bit from the range of numbers.

* Changing representation of objects to allow the NUM type to beKaz Kylheku2009-11-096-66/+104
| | | | | | | | unboxed. If the lowest bit of the obj_t * pointer is 1, then the remaining bits are a number. A lot of assumptions are made: - the long type can be converted to and from a pointer - two's complement. - behavior of << and >> operators when the sign bit is involved.
* First cut at hash tables. One known problem is allocation during gc,Kaz Kylheku2009-11-099-3/+397
