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. + + * gc.c (sweep): Debugging code switched from fprintf to format. + + * lib.c (typ_check, type_check2, car, cdr, car_l, cdr_l, list, + num, chrp, apply, cobj_print_op, dump): Retargetted, with help of new + literals, to new funtions that take string objects, rather than raw C + strings. + (obj_print, obj_pprint): Revamped with support for LIT type. + Retargetted to not use C style I/O functions in streams. + + * lib.h (lit): Macro retargetted to another macro so that it expands + its argument. + (lit_noex): New macro, like lit, but does not macro-expand argument. + (auto_str): New macro. + (static_str): New macro. + + * match.c (debugf, debuglf, sem_error, file_err): Converted from C + string to string object. + (dest_bind, match_line, LOG_MISMATCH, LOG_MATCH, match_files): + Retargetted to new interfaces that take string objects rather than raw + C strings. + (complex_stream): New function. + (do_output_line, do_output, extract): Retargetted from C streams to + object streams. + + * parser.h (yyerrorf): Declaration updated. + + * parser.l (yyerror): Call new yyerrorf interface, using auto_str + macro to dress up C string as a temporary object. + (yyerrorf): Changed from C strings to object strings. + (yybadtoken, grammar): Retargetted to new yyerrorf. + + * stream.c (strm_ops): put_string and put_char function pointers + changed to take object strings rather than C strings. vcformat and + vformat virtuals removed. C formatting is not supported, and vformat is + handled above the stream switch level in one place for all streams. + (common_vformat, stdio_vcformat, string_out_vcformat, cformat, + put_cstring, put_cchar): Functions removed. + (stdio_stream_print, stdio_stream_destroy, stdio_maybe_write_error, + stdio_put_string, stdio_put_char, stdio_close, pipe_close, + string_out_put_char, make_pipe_stream, make_string_input_stream, + make_string_output_stream, make_dir_stream, close_stream, + get_line, put_line, get_char, put_char, put_string): Retargetted to new + string object interfaces. + (stdio_ops, pipe_ops): stdio_vcformat and common_vcformat initializers + (string_out_ops): string_out_vcformat and common_vcformat initializers + removed. + (string_in_ops, byte_in_ops, dir_ops): Two null initializers removed. + (string_out_put_string): Converted to object string interface. + Unnecessary chk_realloc call suppressed. + (get_string_from_stream): Fixed bad call to realloc with incorrect + size. + (vformat_num, vformat_str): New functions, helper to vformat. + (vformat): Rewritten. Is now the formatting engine. + (format, put_string, put_char): Interface converted from C string to + object string. + + * stream.h (vformat, format): Declarations updated. + (vcformat, cformat, put_cstring, put_cchar): Declarations removed. + + * txr.c (oom_realloc_handler, help, txr_main): Retargetted to object + stream and strings. + + * unwind.c (uw_throw, type_mismatch, uw_register_subtype): Retargetted + to new string object interfaces. + (uw_throwf, uw_errorf): Interface changed from C string to object + string. + (uw_throwcf, uw_errorcf): Functions removed. + + * unwind.h (uw_throwf, uw_errorf, type_mismatch): Declarations updated. + (uw_throwcf, uw_errorcf): Declarations removed. + (internal_error): Macro interface changed and retargetted to + object strings. Also, num hygiene problem worked around with local + extern declaration. + (numeric_assert, range_bug_unless): Retargetted to object strings. + + * utf8.c (utf8_to, utf8_dup_from_uc, utf8_dup_from, + utf8_dup_to_uc): Casts of chk_malloc return value added. + 2009-11-15 Kaz Kylheku <kkylheku@gmail.com> Use the 11 tag bit pattern to denote a new type: LIT.
