* More valgrind integration. Vector objects keep displaced pointersKaz Kylheku2009-11-251-0/+13
| | | | | | | | to vector data; they point to element 0 which is actually the third element of the vector. If an object is only referenced by interior pointers, Valgrind reports it as possibly leaked. This change conditionally adds a pointer to the true start of the vector, if Valgrind support is enabled.
* First stab at Valgrind integration. First goal: eliminate falseKaz Kylheku2009-11-251-0/+18
| | | | positives when gc is accessing uninitialized parts of the stack.
* Fix uninitialized memory locations.Kaz Kylheku2009-11-241-0/+12
|
* Switching to keyword symbols for :args and :nothrow.Kaz Kylheku2009-11-241-0/+16
|
* utf8.c (utf8_from_uc): Fix bug introduced several commits ago (portingtxr-025Kaz Kylheku2009-11-241-0/+7
| | | | to C++). Caught by regression test suite. Found using git bisect.
* Version 025Kaz Kylheku2009-11-241-0/+54
|
* Auto-detect what specifiers to use for inline functions.Kaz Kylheku2009-11-241-0/+20
| | | | | Allow compiler command to be set independently of full path for easier compiler switching.
* Changes to make the code portable to C++ compilers, whichKaz Kylheku2009-11-241-0/+35
| | | | can be taken advantage of for better diagnostics.
* Fixed broken yyerrorf. It was still taking char *, and passingKaz Kylheku2009-11-241-0/+16
| | | | | that as an object to vformat, resulting in #<garbage: ...> output.
* Renaming global variables that denote symbols, such that theyKaz Kylheku2009-11-241-0/+63
| | | | have a _s suffix.
* * configure (platform_flags, remove_flags): New config variables.Kaz Kylheku2009-11-231-0/+6
| | | | * Makefile (CFLAGS): Take into account new flags.
* Follow up on 64 bit compilation warnings.Kaz Kylheku2009-11-231-0/+11

* * Makefile (conftest.o): revert change that took CFLAGS fromKaz Kylheku2009-11-231-0/+5
| | | | this target.
* * configure: Don't rely on higher precision arithmetic from the buildKaz Kylheku2009-11-231-0/+7
| | | | | | machine's shell. POSIX requires shell arithmetic to be only signed long. We can't compute the INT_PTR_MAX constant in the shell, but rather generate a constant C expression to compute it.
* Reporting of compile errors during configuration for easierKaz Kylheku2009-11-231-0/+14
| | | | configure debugging.
* * configure: Bugfix in parsing configuration variablesKaz Kylheku2009-11-231-0/+9
| | | | | | | | which contain the = character. * Makefile (conftest.o): Pass full CFLAGS to configuration test builds. If some flags don't work with the compiler, this should be caught.
* * Makefile (CFLAGS): Added -I. so current directory is firstKaz Kylheku2009-11-231-0/+6
| | | | | in the include search path. This is needed for finding generated header files, when building in a separate directory.
* * lib.c (chk_malloc, chk_realloc): Fix diagnosable conversion,Kaz Kylheku2009-11-231-0/+5
| | | | caught by gcc 4.1.1.
* * configure (cross): Print out value of $cross in --help.Kaz Kylheku2009-11-231-0/+9
| | | | | | | * depend.txr: Add "config.h" to list of headers that are not prefixed with $(top_srcdir). * dep.mk: Regenerated.
* Improving portability. It is no longer assumed that pointersKaz Kylheku2009-11-231-0/+70
| | | | | | | | 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 Kylheku2009-11-211-0/+80
| | | | | | | | | | 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.
* * unwind.c (uw_throw): If streams are not initialized,Kaz Kylheku2009-11-201-0/+20
| | | | | | 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.
* * parser.y (grammar): Fix error actions that do not assignKaz Kylheku2009-11-201-0/+5
| | | | a value to $$.
* * match.c (dest_bind): Extended to handle more general formsKaz Kylheku2009-11-201-0/+8
| | | | | | | by using eval_form rather than direct symbol binding lookups. False positive return fixed. (match_line): Fixed merge to use eval_from rather than direct symbol binding.
* * lib.c (flatten): Semantics change. The flatten functionKaz Kylheku2009-11-201-0/+5
| | | | should not map nil -> (nil), but nil -> nil.
* Changing ``obj_t *'' occurences to a ``val'' typedef. (Ideally,Kaz Kylheku2009-11-201-0/+16
| | | | | we wouldn't have to declare object variables at all, so why use an obtuse syntax to do so?)
* * txr.1: Fixed mangled formatting of exception handling example.Kaz Kylheku2009-11-191-0/+4
|
* Get rid of macros in favor of safer inline functions.Kaz Kylheku2009-11-191-0/+16
| | | | | The recent auto_str("byte str") error could have been caught at compile time.
* Version 024.txr-024Kaz Kylheku2009-11-191-0/+13
|
* Use unsigned char * as allocator return value.Kaz Kylheku2009-11-191-0/+10
|
* Following-up on diagnostics obtained by running code through C++Kaz Kylheku2009-11-181-0/+28
| | | | | | compiler. Idea: allocator functions return char * instead of void *, like malloc did in classic pre-ANSI C. That way we are forced to use a cast except when the target pointer is char * already.
* * match.c (match_line, match_files): Fix broken behavior of collectKaz Kylheku2009-11-181-1/+11
| | | | that doesn't match anything.
* Fix total breakage of yyerror and yyerrorf.Kaz Kylheku2009-11-181-0/+7
|
* txr.1: Clarified handling of UTF-8, now that it's precise and portable.Kaz Kylheku2009-11-181-0/+4

* Version 023.Kaz Kylheku2009-11-181-0/+20

* More removal of C99 wide character I/O, and tightening upKaz Kylheku2009-11-171-0/+25

* Whitespace.Kaz Kylheku2009-11-171-1/+1
|
* Removing use of C99 wide character I/O.Kaz Kylheku2009-11-171-0/+21
|
* Warning fixes.Kaz Kylheku2009-11-171-0/+13
|
* * lib.c (chrp): Fix broken is_chr(num) call.Kaz Kylheku2009-11-171-0/+4
|
* * regex.c (nfa_all_states, nfa_closure): visited parameterKaz Kylheku2009-11-171-0/+5
| | | | should be unsigned.
* Fixes for compliance to C89.Kaz Kylheku2009-11-171-0/+26
|
* Version 022.txr-022Kaz Kylheku2009-11-171-0/+18
|
* * Makefile (rebuild): New target. Tired of doing make clean; make.Kaz Kylheku2009-11-161-0/+4
|
* Big round of changes to switch the code base to use the streamKaz Kylheku2009-11-161-0/+96
| | | | | | | | | | | | | | | | | 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.
* Use the 11 tag bit pattern to denote a new type: LIT. This is aKaz Kylheku2009-11-161-0/+20
| | | | | pointer to a C static string, intended for literals. We can now treat literal strings as light-weight objects.
* * lib.c (chr): Take wchar_t argument, not int. Dropped range check.Kaz Kylheku2009-11-151-0/+7
| | | | | | (c_chr): Return wchar_t not int. * lib.h (chr, c_chr): Declarations updated.
* Version 021 preparation.txr-021Kaz Kylheku2009-11-151-0/+45
| | | | Bumped version numbers, and cleaned up trailing whitespace from some files.
* Provide both char * and unsigned char * interfaces in UTF-8 module.Kaz Kylheku2009-11-141-0/+16
| | | | Fix unsigned and plan char * mixing.
* dep.mk: Regenerated.Kaz Kylheku2009-11-141-0/+2
