| | | | | | | | | | | | | | in C headers which are extensions to standard C, like popen or fileno, in response to standard feature selection macros like -D_POSIX_SOURCE. MinGW and Cygwin are offenders. These platforms hide the declarations when gcc is in -ansi mode, by testing for __STRICT_ANSI__. Turns out, however, that -U__STRICT_ANSI__ on the gcc command line strips this away, causing the declarations to be revealed. * lib.c, parser.l, stream.c, utf8.c: Removed the declarations which compensated for the above problem. Yippee! Fuck you, stupid Cygwin troglodytes, and the MinGW horse you rode in on. http://cygwin.com/ml/cygwin/2011-10/msg00131.html
* * configure (lang_flags): Let us switch from using _XOPEN_SOURCE=2Kaz Kylheku2014-01-101-2/+2
| | | | | | | | | | | | | | | | | | | to _POSIX_C_SOURCE=199309L and _BSD_SOURCE. In the .exe suffix test, try harder to redirect ls's output. Test for fork stuff now needs <sys/types.h> evidently; <unistd.h> does not necessarily pid_t, even though it defines functions that return and accept pid_t! The timegm test no longer needs _SVID_SOURCE since _BSD_SOURCE covers it, and so we end up not using _SVID_SOURCE any more. New tests for usleep and nanosleep. The test for setenv is not conditional on timegm failing. * eval.c: Include <time.h> and conditionally <windows.h>. (usleep_wrap): New function. (eval_init): New usleep_wrap function registered as usleep intrinsic. * lib.c: Only define setenv and unsetenv if we don't have timegm, because only in that situation they are used.
* * configure: Generate HAVE_VALGRIND as #define-d to 1, rathernKaz Kylheku2014-01-101-5/+5

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

* Changing the tokenizer to get rid of IDENT, KEYWORD and METAVARKaz Kylheku2013-12-151-3/+4
| | | | | | | | | | | | | | | | | | | | | token categories, replaced by a single one called SYMTOK. Package prefixes are now recognized and processed in tokens. * lib.c (delete_package): Fix problem in no-such-package error case: it would always report nil as the name. (intern): Fix nonsensical error message: in the no-such-package case it would report that the symbol exists already. * parser.l (grammar): Occurences of KEYWORD, METAVAR, and IDENT scrubbed. All rules reporting any of these now return SYMTOK. The main one of these is greatly simplified. * parser.y (sym_helper): New function. (char_from_name): const qualifier inside param's type declaration. (grammar): IDENT, KEYWORD and METAVAR tokens are gone. New token SYMTOK. Grammar refactored around SYMTOK and using the new sym_helper function. (char_from_name): Updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that accurate lazy lists are not suitable for real time use, where we want the TXR program to respond immediately to matching some datum. I'm implementing a simple, naive variant of lazy stream lists which simply populates the lazy cons by reading from the stream when the car or cdr fields are accessed. This type of stream can never be nil (empty list) even if the file is empty; in that case it will be (nil) and in general, it will have a spurious nil item at the end instead of ending in a string. (An adjustment was made in match.c to detect this; more will be needed.) I'm adding attributes to streams so streams can now have a "real-time" attribute. When a lazy string list is constructed over a real-time stream, the simple implementation is used. File streams are automatically real-time if (on Unix) they are tied to tty streams. Tail streams are also real-time. More work is needed to achieve the goal of this change, but this is a big step in the right direction. * configure: Detect isatty function. * lib.c (simple_lazy_stream_func): New static function. (lazy_stream_cons): Use simple implementation for real-time streams. * match.c (match_files): Do not call match_line_completely with a data line that is nil (as a result of simple lazy list over a real-time stream). A nil item in a lazy list of strings is treated as eof. * stream.c (real_time_k): New symbol variable. (struct strm_ops): New members: get_prop, set_prop. (struct stdio_handle): New member: is_real_time. (stdio_get_prop, stdio_set_prop): New static function. (stdio_ops, tail_ops, pipe_ops): stdio_get_prop and stdio_set_prop funtions wired in. (make_stdio_stream_common): Attribute streams as real-time if they are tty devices. (make_tail_stream): Tail streams are real-time attributed. (stream_set_prop, real_time_stream_p): New functions. (stream_init): Initialize real_time_k. * stream.h (real_time_k): Declared. (real_time_stream_p, stream_set_prop): Likewise.

| | | | | | | | | | | | | | | | | | | have stricter diagnosis for configure tests. (have_timegm, need_svid_source, need_bsd_source): New variables. sys/stat.h test only declares static data and compiles an object file. Adding tests for timegm, tzset, setenv and unsetenv. * eval.c (eval_init): Register new intrinsic, make_time_utc. * lib.c (make_time_impl): New static function. (make_time): Reimplemented as call to make_time_impl. (timegm_hack): New conditionally-defined static function. (make_time_utc): New function. * lib.h (make_time_utc): Declared. * txr.1: make-time-utc documented.

(func_n5, func_n6, func_n7, func_n5v, func_n6v, func_n7v): New functions. (obj_init): Initialize auto_k. (make_time): New function. * lib.h (functype_t): New enum members: N5, N6, N7. (struct func): New members: n5, n6, n7, n5v, n6v, n7v. (auto_k, func_n5, func_n6, func_n7, func_n5v, func_n6v, func_n7v, make_time): Declared.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | deviations from C90, like mixed declations and statements. GCC doesn't diagnose these without the --pedantic flag. * configure: GCC's --ansi flag should be spelled -ansi. * lib.c (split_str, obj_print): Reorder declaration before statements. (make_sym): Fix similar problem by eliminating a statement. (funcall1, funcall2, funcall3, funcall4): Use assignment to initialize local array with non-constant elements. This is actually good for performance because we only initialize those parts of the array that we use. * lib.h (struct func): Change functype member to unsigned, since enum-typed bitfields are a GCC extension. * match.c (ml_all, mf_all): Use assignments to initialize local struct with non-constants. (do_txeval, v_collect): Slightly revise unwinding macrology with help of new macros to avoid mixing declarations and statements. (spec_bind): Removed spurious semicolon from macro expansion. (v_gather): Reorder two lines to avoid mixed decls and statements. (match_filter): Move declaration of ret a few lines up, ahead of statements. * unwind.c (uw_pop_until): New function. * unwind.h (uw_pop_until): Declared. (uw_mark_frame, uw_fast_return): New macros.
* Improving behavior of op and fixing a bug.Kaz Kylheku2013-10-061-1/+1
| | | | | | | | | | | | | | | | | | | | | Explicitly specifying @rest using (op ... . @rest) did not work at all. The then-func agument of iff and iffi may now be nil. * eval.c (format_op_arg): New static function. (transform_op): Handle dotted lists ending in @rest or @<num>. (supplement_op_syms): New static function. (expand_op): Add missing numeric arguments, so that all 1 through n are in the list. Trailing rest is now added under different conditions. * lib.c (do_iff): Give thenfun the same behavior on nil that elsefun enjoys. * txr.1: Updated.

| | | | | | | | | | | | | | | | | | | Added lazy-stringp. Changing names of length-str-{gt,ge,lt,le} to be consistent with the >, >=, < and <= functions. * lib.c (lazy_stream_func): Greatly simplified implementation. The lazy list now continues by means of recursing via an optimized version of lazy_stream_cons called lazy_stream_cont. The environment structure is simplified to just hold the next item, rather than a pointless list. The pointless setting of lcons->lc.func to nil is also removed; this is always done by the caller. (lazy_stream_cont): New static function, similar to lazy_stream_cons, but optimized by not consing up a new function and new environment cell. (lazy_stream_cons): The environment for the update function is simplified to just a single cons. * txr.1: Documented lazy string functions and lazy-stream-cons.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | can walk table content in different ways. * eval.c (op_dohash): Follow interface change of hash_next. (eval_init): hash-keys, hash-values, hash-pairs and hash-alist intrinsics introduced. * filter.c (trie_compress): Follow interface change of hash_next. * hash.c (hash_next): Silly interface which takes a pointer to the iterator has changed to just take the iterator. The function unambiguously returns nil when the iteration ends, so there is no need to set the iterator variable to nil. (maphash): Follows interface change of hash_next. (hash_keys_lazy, hash_values_lazy, hash_pairs_lazy, hash_alist_lazy): New static functions. (hash_keys, hash_values, hash_pairs, hash_alist): New functions. * hash.h (hash_next): Declaration updated. (hash_keys, hash_values, hash_pairs, hash_alist): Declared. * lib.c (make_half_lazy_cons): New way of constructing lazy cons, with the car field specified. It simplifies situations when the previous cons computes the car of the next one. Why hadn't I thought of this before? * lib.h (make_half_lazy_cons): Declared. * txr.1: Doc stubs for new hash functions. * txr.vim: Highlighting for new hash functions.
