* Improved debugging. Debug nesting depth counter maintainedKaz Kylheku2012-01-211-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and used for next/step/finish stepping. * Makefile (OBJS): debug.o moved to OBJS-y or OBJS-. (OBJS-y, OBJS-): New variables. $(PROG): Depends on OBJS-y also. clean: clean $(OBJS-y). depend: include $(OBJS-y) in dependency generation. * configure: Underscores and dashes are interchangeable in configure variables. (yaccname_given, yacc_given): Default value is y, not yes. (debug_support): New config variable. (CONFIG_DEBUG_SUPPORT): New config.h symbol. * debug.c (debug_depth): New global variable. (debug_block_s): New symbol variable. (next_depth): New static variable. (debug): Renamed some commands. Introduced separate next, step and finish. (debug_init): debug_block_s initialized. * debug.h (debug_depth, debug_block_s): Declared. (debug_enter, debug_leave, debug_return): New macros. (debug_check, debug_init): Conditionally defined based on if this is a debug build. * dep.mk: Regenerated. * eval.c (eval): Instrumented with debug_enter, debug_leave, debug_return. * match.c (match_line, v_fun, match_files): Likewise. * txr.c (txr_main): Bail if -d or --debug used in build that lacks debug support.
* * Makefile (OBJS): new object file, rand.o.Kaz Kylheku2011-12-211-1/+1
| | | | | | | | | | | | * eval.c: Includes rand.h header. (eval_init): New variable and functions from rand module registered. * lib.c: Includes rand.h header. (init): Call rand_init. * rand.c: New file. * rand.h: New file.
* * Makefile (distclean): use rm -rf on mpi directory.Kaz Kylheku2011-12-211-1/+2

* * Makefile (repatch): New phony target.Kaz Kylheku2011-12-131-2/+7
| | | | (distclean): Remove mpi directory.
* Bignum support, here we go!Kaz Kylheku2011-12-091-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bignums, based on Michael Fromberger's MPI library, are integrated into the input syntax, stream output, equality testing, the garbage collector, and hashing. The plus operation handles transitions between fixnums and bignums. Other operations are still fixnum only. * Makefile (CFLAGS): Add mpi directory to include file search. (OBJS): Include new arith.o module and all of MPI_OBJS. (MPI_OBJS, MPI_OBJS_BASE): New variables. * configure (mpi_version, have_quilt, have_patch): New variables. Script detects whether patch and quilt are available. Unpacks mpi library, applies patches. Detects 128 bit integer type. Records more information in config.h about the sizes of types. * dep.mk: Updated. * depend.txr: Make work with paths that have directory components. * eval.c (eval_init): Rename of nump to fixnump. * gc.c (finalize, mark_obj): Handle BGNUM case. * hash.c: (hash_c_str): Changed to return unsigned long instead of long. (equal_hash): Handle BGNUM case. (eql_hash): Handle bignums with equal-hash, but other objects as eq. * lib.c (num_s): Variable renamed to fixnum_s. (bignum_s): New symbol variable. (code2type): Follow rename of num_s. Handle BGNUM case. (typeof): Follow rename of num_s. (eql): Handle bignums using equal, and other types using eq. (equal): Handle BGNUM case. (chk_calloc): New function. (c_num): Wording change in error message: is not a fixnum. (nump): Renamed to fixnump. (bignump): New function. (plus): Function removed, reimplemented in arith.c. (int_str): Handle integers which are too large for wcstol using bignum conversion. Base 0 is no longer passed to wcstol but converted to 10 because the special semantics for 0 would be inconsistent for bignums. (obj_init): Follow rename of num_s. Initialize bignum_s.
* Task #11436Kaz Kylheku2011-11-261-1/+1

(funcall, funcall1, funcall2, funcall3, funcall4): Handle variadic and interpreted functions. (acons, acons_new, acons_new_l, aconsq_new, aconsq_new_l): Reordered arguments for compatibility with Common Lisp acons. (obj_init): Special hack to prepare hash_s symbol, which is needed for type checking inside the hash table funtions invoked by make_package, at a time when the symbol is not yet interned.

(ll_hash): Renamed to equal_hash. (eql_hash): New static function. (cobj_hash_op): Follows ll_hash rename. (hash_grow): Use new function indirection to call hashing function. (make_hash): New argument to specify type of hashing. Initialize new members of struct hash. (gethash_l, gethash, remhash): Use function indirection for hashing and chain search and update. (pushhash): New function. * hash.h (make_hash): Declaration updated with new parameter. (pushhash): Declared. * lib.c (eql_f): New global variable. (eql, assq, aconsq_new, aconsq_new_l): New functions. (make_package): Updated to new three-argument make_hash.

(ALL, SOME, NONE, MAYBE, CASES, CHOOSE, GATHER, AND, OR, END, COLLECT, UNTIL, COLL, OUTPUT, REPEAT, REP, SINGLE, FIRST, LAST, EMPTY, DEFINE, TRY, CATCH, FINALLY, ERRTOK, '('): Reclassified as lineno type. In the grammar, these keywords can thus provide a stable line number from the lexer. (grammar): Numerous rules updated to add constructs to the line number hash tables via the rl helper. * dep.mk: Updated. * Makefile (depend): Use the installed, stable txr in the system path to update dependencies rather than locally built ./txr, to prevent the problem that txr is broken because out out-of-date dependencies, and thus cannot regenerate dependencies.
* * Makefile (%.ok: %.txr): Use unified diff for showingKaz Kylheku2011-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | differences between expected and actual test output. * parser.l (yybadtoken): Handle new terminal symbol, SPACE. New rule for producing SPACE token out of an extent of tabs and spaces. * parser.y (SPACE): New terminal symbol. (o_var): New nonterminal. I noticed that the var rule was being used for output elements, and the var rule refers to elem rather than o_elem. A new o_var rule is a simplified duplicate of var. (elem): Handle SPACE token. Transform to regex if it is a single space, otherwise to literal text. (o_elem): Handle SPACE token in output. * tests/001/query-2.txr: This query depends on matching single spaces and so needs to use escapes. * tests/001/query-4.txr, test/001/query-4.expected: New test case, based on query-2.txr. It produces the same output, but is simpler thanks to the new semantics of space. * txr.1: Documented.

* * Makefile (CFLAGS): Better test for g++, when removingKaz Kylheku2009-12-031-1/+1
| | | | | | warning options not appropriate for g++. Sometimes g++ may be called something that dosn't end in g++, like g++4.
* * Makefile (tests): Don't depend on the executable. Otherwise,Kaz Kylheku2009-12-021-7/+10
| | | | | | | | | during make install-tests, if it doesn't exist in the install directory, a gcc compile command gets deposited into the run.sh generated script. (install-tests): Fixes to make this work when using a separate build directory. Split the cpio -p job into a cpio -i piping into cpio -o.
* * Makefile (install-tests): New target. Provides a way to make theKaz Kylheku2009-12-021-0/+12

* Fix annoyances with dependency generation, such as picking up localKaz Kylheku2009-12-021-1/+1
| | | | files that are not in the project.
* * Makefile (CFLAGS): If the compiler matches the pattern %g++,Kaz Kylheku2009-11-281-0/+4
| | | | | then remove some C-front-end-specific warnings from CFLAGS, which the g++ front end will complain about.
* * Makefile (CFLAGS): add -Dlint to CFLAGS when compiling y.tab.o.Kaz Kylheku2009-11-281-0/+4
| | | | | | This suppresses some warnings from a byacc-generated parser, and gets rid of a useless static sccsid array. May help with Bison-generated parser also.
* Switching to DESTDIR convention for install.Kaz Kylheku2009-11-271-5/+16
| | | | | Make install step does some things more correctly now, without relying on the install program.
* Not all systems have a yacc alias for the yacc program.Kaz Kylheku2009-11-261-1/+5
| | | | | txr is known to work with two yacc implementations: GNU Bison and Berkeley yacc. Let's add some auto-detection for yacc.
* Auto-detect what specifiers to use for inline functions.Kaz Kylheku2009-11-241-3/+3
| | | | | Allow compiler command to be set independently of full path for easier compiler switching.
* * configure (platform_flags, remove_flags): New config variables.Kaz Kylheku2009-11-231-3/+4

* * configure: Bugfix in parsing configuration variablesKaz Kylheku2009-11-231-2/+0
| | | | | | | | 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 Kylheku2009-11-231-1/+1
| | | | | in the include search path. This is needed for finding generated header files, when building in a separate directory.
* Improving portability. It is no longer assumed that pointersKaz Kylheku2009-11-231-1/+15
| | | | | | | | 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.
* Get rid of macros in favor of safer inline functions.Kaz Kylheku2009-11-191-1/+2
| | | | | The recent auto_str("byte str") error could have been caught at compile time.

* New testcase which does some UTF-8 scanning, Unicode regexes,Kaz Kylheku2009-11-131-0/+1
| | | | and @(freeform).
* Allow -c scripts to not have a trailing newline.Kaz Kylheku2009-11-131-1/+6
| | | | | | | | | | | | | 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.
* Big conversion to wide characters and UTF-8 support.Kaz Kylheku2009-11-111-1/+1
| | | | | | | | | 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.
* First cut at hash tables. One known problem is allocation during gc,Kaz Kylheku2009-11-091-0/+1
| | | | due to use of boxed numbers for vector access.
* Get rid of accidentally commited debug $(warning ...).Kaz Kylheku2009-11-041-2/+0
