* Purge stray occurrences of "void *" from code base.Kaz Kylheku2014-10-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (cobj_print_op): In the format call, cast the C pointer to val, since the ~p conversion now takes a val rather than void *. (cptr_equal_op, obj_print, obj_pprint): Remove cast to void *, since obj now already has the type that ~p expects. * lib.h (struct any): Use mem_t * instead of void *. * parser.h (yyscan_t): Repeat the definition from inside the Flex-generated lex.yy.c. (yylex_init, yylex_destroy, yyget_extra, yyset_extra): Re-declare using yyscan_t typedef in place of void *. * parser.l (yyget_column, yyerrprepf): Re-declare using yyscan_t. (grammar): Use yyg in place of yyscanner in calls to yyerrprepf. * parser.y (yylex, %lex-param): Use yyscan_t instead of void *. (parse): Use yyscan_t for local variable. * signal.c (stack): Change type from void * to mem_t *. * stream.c (vformat): Conversion specifier p extracts val instead of void *. (run): Use casts that only remove const, not all the way to void *. * txr.1: Documented p conversion specifier of format. * Makefile (OBJS-y): Initialize with := to make sure it is a simple variable, and not a macro. (SRCS): New variable, listing source files. (enforce): New rule for enforcing coding conventions. Currently checks for void * occurrences.

(pax tar zip): New targets. * configure (txr_ver): Version now added to config.make, passed through to txr.c. (gen_config_make): bindir, datadir and mandir are established using gmake's regular macro assignment (=) rather than expanding assignment (:=). This allows us to override the prefix variable after configure time. * lib.h (wli_noex): New macro. (wli): Retarget to wli_noex, so that argument is subject to macro replacement. * txr.c (version): Use TXR_VER defined on compiler command line, rather than hard-coded string literal.
* 2014-06-10 Kaz Kylheku <kaz@kylheku.com>Kaz Kylheku2014-06-101-5/+11
| | | | | | | | | | | | | | | * Makefile (PROG): Removing ./ prefix from variable name; adding it to invocations of $(PROG) in some rules. (txr.o): Pass several strings as macros on the command line: TXR_REL_PATH, EXE_SUFF and PROG_NAME. * configure (bindir, datadir, mandir): These variables become just relative paths from the prefix. * txr.c (sysroot): Use the TXR_REL_PATH, EXE_SUFF and PROG_NAME preprocessor symbols defined on the command line to avoid hard-coding strings like "bin/txr" and "bin/txr.exe" which actually should reflect the value of the bindir variable.

* * Makefile (lex.yy.c): Remove lex.yy.c before trying to regenerate it.Kaz Kylheku2014-03-021-1/+3
| | | | | | (y.tab.c, y.tab.h): Remove y.tab.c before running yacc. Write-protect y.tab.c, not $@, which could expand to the y.tab.h target if that is what triggered the rule.

* Long overdue MinGW port maintenance.Kaz Kylheku2014-01-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile: Use new EXE variable from config.mk. * configure (exe, have_windows_h): New variables. Handle situations with .exe suffix; on MiGW, the rm command doesn't work on executables if the .exe suffix is not given. New tests for localtime_r and gmtime_r. * lib.c: Supply declarations which are missing on MinGW because we use gcc -ansi, because MinGW doesn't follow established conventions like -D_POSIX_SOURCE. Supply definitions for gmtime_r, localtime_r, setenv and unsetenv. * parser.l: Supply declarations which are missing on MinGW. * signal.h (async_sig_enabled): Declare differently based on HAVE_POSIX_SIGS. Misspelled typedef fixed in the code for !HAVE_POSIX_SIGS that has hitherto not been compiled. (sig_mask): Wrap declaration in #ifdef HAVE_POSIX_SIGS because it relies on sigset_t. * stream.c: Supply declarations which are missing on MinGW. Include <windows.h> if we have it. (sleep): Define for Windows. (statf): Handle missing st_blksize and st_blocks members in struct stat. (stream_init): Handle numerous missing S_* macros. * utf8.c: Supply declarations which are missing on MinGW.

* syslog support; bitwise logior and logand functions become variadic.Kaz Kylheku2013-12-101-3/+4
| | | | | | | | | | | | | | | | | | | | * Makefile: Use -iquote to restrict our #include search paths from being processed for #include <...>. Add syslog.o to OBJS-y if have_syslog is y. * configure (have_syslog): New variable, set by detecting syslog API. * eval.c (eval_init): logand and logior registrations changed to go to variadic versions.

* * Changelog: missing entries reconstructed.Kaz Kylheku2013-11-271-1/+1
| | | | | | | | | | | | | * Makefile (conftest.clean): Use @ to suppress output. * configure (have_unistd): New variable. Set true by every successful test that compiles something that contains #include <unistd.h>. HAVE_UNISTD_H is conditionally generated in config.h based on this variable. Minor cleanup. * parser.l: Inclusion of <unistd.h> wrapped in #if/#endif. * stream.c: Conditional inclusion of <unistd.h> based on new HAVE_UNISTD_H symbol.
* * Makefile (clean): depends on conftest.cleanKaz Kylheku2013-10-281-1/+7
| | | | | | | | (conftest.clean): New target. * configure: Use "make conftest.clean" to clean up conftest stuff. Note that there was a bug here: brace expansion was used, but the shell is /bin/sh, so conftest.err wasn't being removed.
* Fixes for configuring and building in a separate directory.Kaz Kylheku2012-04-201-4/+4
| | | | | | | | | | * configure: MPI is now extracted and patched in the build directory, not in the source directory. * Makefile (CFLAGS): Refer to mpi headers relative to current directory, not $(top_srcdir). (repatch): Run MPI repatching steps in correct directory. (clean): Remove extracted MPI from build directory.
* More NetBSD porting.Kaz Kylheku2012-04-101-1/+1
| | | | | | | | | | | | | | | | | | * Makefile (EXTRA_FLAGS): Handy new variable for additional ad-hoc CFLAGS. Needed by a new test in configure. * configure: Check for annoying warnings about char being used as an array subscript when calling the macros from <ctype.h>. If this occurs, suppress it by #undef-ing the macros. (lang_flags): Switching fromm _XOPEN_SOURCE to _XOPEN_SOURCE=2 because this is needed on NetBSD to obtain declarations of popen and pclose. * stream.c (pipe_close): If we don't have the WIFCONTINUED macro, then define it to expand to zero. It's absent on NetBSD and they already seem to have a hack for this because there is a warning about the function not being defined, but then the program links anyway. Let's do it properly and not rely on their hack.
* * Makefile (conftest.ccver): New phony target.Kaz Kylheku2012-04-101-0/+4
| | | | | | | * configure: The test for non-working 128 bit integers in the gcc used by NetBSD 5.1 is not good enough to catch the bug. Adding a test which will assume that gcc 4.3.x and lesser does not have working 128 bit types.
* Fixes to get configure ccname=g++ working on OSX Lion.Kaz Kylheku2012-04-071-1/+1
| | | | | | | | | | | | | | | | * Makefile (conftest.syms): Use -n flag in nm so that the output is not alphabetically sorted, but numerically. We need this to get the symbols ordered by increasing offset. * configure (read_syms): New function. Factors out logic used in two places for reading the output of nm. On OSX Lion, it looks like we do not get symbol sizes but offsets only, when compiling with g++. The symbols are in an S section. When compiling with gcc, we get a common C section with symbol sizes. So the hack is to use the deltas between offsets to get the sizes. The objects had to be re-ordered in decreasing rank so alignment doesn't create padding that will get counted as the size. Interleaved dummy objects of type char should also work.
* * Makefile (TXR_ARGS): Pass new file to tests/009/json.txr test.Kaz Kylheku2012-03-231-1/+1
| | | | | | | | | | * tests/009/json.expected: Updated. * tests/009/json.txr: Updated source. Translates to a more native representation with vectors and hash tables. Numbers go to floating point instead of remaining as strings. * tests/009/pass1.json: New file: a test case from json.org.
* * Makefile: link in -lm, which is needed now on some systems.Kaz Kylheku2012-03-211-1/+1
| | | | | * arith.c (plus, minus): Eliminated some unnecessary (double) casts. (abso, mul): Floating support.

(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.

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.

(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.

(obj_init): gc-protect and initialize new variable eql_f. * lib.h (eql, assq, aconsq_new, aconsq_new_l): Declared. * match.c (dir_tables_init): Updated to there-argument make_hash. * parser.h (form_to_ln_hash, ln_to_forms_hash): Global variables declared. * parser.l (form_to_ln_hash, ln_to_forms_hash): New global variables. (grammar): Set yylval.lineno for tokens that are classified to that type in parser.y. (parse_init): Initialize and gc-protect new global variables. * parser.y (rl): New static helper function. (%union): New member, lineno. (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.
