* * Makefile (enforce): Update error error message.Kaz Kylheku2015-03-241-6/+10
| | | | | | * configure (have_git): Don't set this variable if the TXR repository is missing, even if git is installed. I.e. have_git means have have the tool and the repo.

* On Windows, add icon and identifying meta-data to executable.Kaz Kylheku2015-01-311-1/+13
| | | | | | | | | | | | | | | * Makefile (EXTRA_OBJS-y): New variable. (WINDRES): New recipe. * configure: Check for presence of windres, and generate add_win_res variable in config.make. * win/txr.xcf: New file: GIMP project for icon. * win/txr.ico: New file: icon with three sizes generated from GIMP project. * win/txr.rc: New file.

* Fix for LLVM wchar_t literals not being four byteKaz Kylheku2015-01-121-19/+7
| | | | | | | | | | | | | | | | | aligned, affecting OS X port. * configure: Detect a SIZEOF_WCHAR_T when detecting integer type that will hold a pointer. In the lit_align test, if we are on Apple Mac OSX, use a lit_align of 2, so the logic kicks in for padding literals and handling misalignment. * lib.h (litptr): Add a case for LIT_ALIGN < 4 and SIZEOF_WCHAR_T == 4. In this case we do the arithmetic on the pointer using short *, and then convert to wchar_t. * HACKING: New section 2.4.3 about new wchar_t hack.
* * glob.c: New file.Kaz Kylheku2015-01-111-0/+30
| | | | | | | | | | | | | | | | | | | | (glob_wrap, glob_init): New functions. (errfunc_thunk): New static function. * glob.h: New file. * txr.c (main): call glob_init if HAVE_GLOB is defined. * configure (have_glob): New variable. (gen_config_make): Add have_glob to config/config.make. Detect glob function and set have_glob, and add HAVE_GLOB to config/config.h. * Makefile (OBJS): Include glob.h if have_glob is "y". * genvim.txr: Scan glob.c for functions and variables also. * txr.1: Documented glob and glob-related variables.

* Build bugfix: if a config.h header exists in $(top_srcdir),Kaz Kylheku2014-12-121-76/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | then that header is used when building in a separate directory, instead of the config.h generated in that directory. To fix this, we move config.h into a config/ subdirectory. The $(top_srcdir)/config is not in the include search path when buiding in a separate build directory. While we are at it, let's move all the configure materials generated by the configure script into config/. * Makefile: include config/config.make at the top. Removing the rule which asserts the existence of configuration based on the presence of config.make. (CFLAGS): Add $(conf_dir) to include search path with -iquote. (notconfigured): New conditionally-defined target for producing the error message when the build system is not configured. (NL, DEP): New variables. ($(OBJS)): Make dependent on config/config.make and config/config.h with help of DEP macro. (opt/lex.yy.o, dbg/lex.yy.o): Express dependency using DEP. (y.tab.h): Split off as a dependent on y.tab.c rather than a co-target in the rule. The rule has a body to handle the situation when y.tab.h is missing for some reason, but y.tab.c already exists (and so won't be re-made, and so y.tab.h won't be remade). * configure: Require GNU Make 3.81 rather than 3.80. (conf_dir): New variable. (config_h, config_make, config_log): New variables. These are used in place of config.h, config.make and config.log. Add conf_dir to config.make variable.
* * configure: typo in message.Kaz Kylheku2014-12-111-1/+1

* * configure (have_git): New variable and configure test for git.Kaz Kylheku2014-12-111-0/+14
| | | | | * Makefile (SRCS): Only set if git is available. (enforce): Fail if we don't have git.
* Test output goes to tst/ now.Kaz Kylheku2014-12-091-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | * Makefile (TESTS_OUT): We don't need to refer to top_srcdir. Add the tst/ prefix to .out paths. Find must be used with -H because tests is a symlink for out-of-tree build directories. (tests/*): All target-specific assignments are moved to tst/tests/* paths, and top_srcdir is no longer used in the right hand side values. (%.out): Becomes (tst/%.out). (%.ok): need to compute .expected name from .out differently to account for tst/ prefix. (tests.clean): Just remove the tst directory. (install-tests): Remove the tst directory first so test commands are forced to run (though it is a dry run). We no longer need to switch to top_srcdir to find the .txr files, nor do we have to filter out .out files from the tests tree. We no longer have to switch to top_srcdir in the recursive make. Also, show the installation of tests using ABBREV3. * configure: When configuring in a separate directory, symlink the tests directory back to the source tree. Since there are now three things being symlinked, rewrote that as a loop. The recommendation to build in a separate directory is just a note, not a warning.
* Debug builds optional with --debug-also config option.Kaz Kylheku2014-12-071-0/+14
| | | | | | | | | * Makefile (PROG): Variable removed, now set in config.make. (all): Target now depends on $(BUILD_TARGETS) variable, set in config.make. * configure (debug_also) New variable. (gen_config_make): Generate PROG and BUILD_TARGETS variables.
* * configure: Bugfix: the "share" directory has to beKaz Kylheku2014-12-051-0/+2

| | | | | | | | | | | | only causes build issues on some systems where it is not provided in the standard location, or is not cross-compiled properly. * Makefile (LEXLIB): Reference to variable removed. * configure (lexlib): Variable removed. (LEXLIB): config.make variable not generated. * parser.l (yywrap): Provide this trivial function as inline.

(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.

| | | | | | | | | | | | | | | * 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.

* * configure (lang_flags): Removing -D_BSD_SOURCEKaz Kylheku2014-06-051-2/+39
| | | | | | | | | | | | from lang_flags. Adding a test for determining which flag reveals BSD functions. This is due to the braindamaged way feature selection macros work on FreeBSD. There is no way to say "give me only the functions from a certain version of the Unix spec, plus traditional BSD functions", so we have to resort to using the internal symbol __BSD_VISIBLE. Also, changing the detection test for daemon function to the pointer-based approach.
* * configure (lang_flags): drop -D_POSIX_C_SOURCE=199309L.Kaz Kylheku2014-06-041-1/+1

* Changes for FreeBSD 9.Kaz Kylheku2014-06-041-2/+1
| | | | | | | | | * configure: Use pointer-based test for timegm, because -Werror=implicit-function-declaration does not work in the gcc 4.2 used on FreeBSD 9. * parser.l: Check for Flex 2.5.9 and earlier which don't have yylex_destroy. Thanks to Marcus Breiing.
* * configure: Changes for building on Solaris 10 using theKaz Kylheku2014-06-041-7/+8
| | | | | | | | | /usr/bin/xpg4/sh shell. Solaris' /bin/sh does not like test -e. Adding break to the new shell existence testing loop so we use the first shell in the list. Solaris wants _XOPEN_SOURCE=500 to reveal certain functions. Fix breakage in the make utility detection, and also use the $make variable everywhere instead of make.
* * configure: Defend against legacy, non-POSIX /bin/sh implementations.Kaz Kylheku2014-06-041-0/+21
| | | | | | | We boostrap using #!/bin/sh, but try to detect a better shell and re-execute the script with that shell. Furthermore, we now set up the SHELL variable in config.make, so that make uses that shell for executing build recipes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | segmentation fault that occurs when running out of stack space, and escape by throwing an exception. Also, bugfix: save and restore the gc enable/disable state. Without this, if we are ever running cod in a gc disabled state and it jumps out, gc stays disabled. * configure: added check for sigaltstack. * gc.h (gc_enabled): Declaration added for existing variable. * signal.c (is_cpu_exception): New static function. (sig_handler): For cpu_exception type signals that pertain to the execution of some instruction, turn on async_sig_enabled, so that the signal is not deferred. Otherwise we will just return without calling the user-defined handler, restart the instruction and get into a loop. Also, disable gc around the handler just in case. One issue is that we might be on an alternate stack, which gc won't like. (setup_alt_stack, teardown_alt_stack): New static functions. (set_sig_handler): If we have sigaltstack, and are asked to set up a SEGV handler, then set it up on the alternate stack. * signal.h (extended_jmp_buf): Adding new member, gc. (extended_setjmp, extended_longjmp): use gc member to save and restore the gc_enable state across setjmp and longjmp.
* * configure: new test for fcntl.Kaz Kylheku2014-03-111-0/+24
| | | | | | | | | | | * stream.c (open_process): Fixed off-by one erroneous value of nargs, causing memory leak of one string. Fixed memory leak on fork failure. Fixed a deadlock that can occur in the pipe close function when multiple pipes are in existence. This is fixed by setting the FD_CLOEXEC flag on the pipe file descriptor. Without this, one child process can hold another's pipe open, causing that other one not to terminate when we're trying to shut it down, resulting in that child blocked on a write, while we block on waitpid.
