2015-08-08 Kaz Kylheku <kaz@kylheku.com>
Discontinuing ChangeLog.
* ChangeLog: renamed to ChangeLog-2009-2015, and discontinued.
Changes will be tracked only in the git commit messages
from now on and not duplicated into the ChangeLog.
2015-08-08 Kaz Kylheku <kaz@kylheku.com>
Version 111.
* RELNOTES: Updated.
* configure, txr.1: Bumped version and date.
* share/txr/stdlib/ver.tl: Likewise.
* tl.vim, txr.vim: Regenerated.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
C++ upkeep: conversions, clashes, warnings.
* glob.c (glob_wrap): Fix signed/unsigned comparison.
* stream.c (make_null_stream): Fix convert beign used
where coerce is needed.
* sysif.c (dup_wrap): Fix use of C++ new keyword.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
C++ static forward issue.
* lib.h (static_forward, static_def): New macros
for dealing with C++ static forward declaration problem.
* syslog.c (syslog_strm_ops): Use static
forward macros.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
C++ upkeep: resolve multiple definitions of fun_k.
* eval.c (fun_k): Global definition removed.
(eval_init): Do not initialize fun_k here.
* filter.c (fun_k): Definition removed.
(filter_init): Do not initialize fun_k.
* filter.h (fun_k): Declaration removed.
* lib.c (fun_k): Defined in this file now.
(obj_init): Initialize fun_k here.
* lib.h (fun_k): Declare here.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
* Makefile (SRCS): When top_srcdir is blank, elide the entire
--work-tree argument to git. On Cygwin, git throws a strange error
message when --work-tree is given a blank argument.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
* stream.c: Include <wctype.h> header for iswprint.
Needed on Cygwin.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
* sysif.c (w_lstat): If we don't have S_IFLINK, implement
w_lstat as an alias to w_stat. This helps build on MinGW.
2015-08-07 Kaz Kylheku <kaz@kylheku.com>
Change to different exception for debugger quit.
* debug.c (debug_quit_s): New global variable.
(debug): Throw debug-quit, not query-error.
(debug_init): Initialize debug_quit_s.
2015-08-06 Kaz Kylheku <kaz@kylheku.com>
* debug.c (help): Rearrange menu. Show missing quit command.
2015-08-06 Kaz Kylheku <kaz@kylheku.com>
Suppress debug stepping into auto-loaded library code.
* debug.c (debug_set_state, debug_restore_state): New functions.
* debug.h (debug_state_t): New type.
(debug_set_state, debug_restore_state): Declared, and defined
as dummy macros in non-debug-support build.
* lisplib.c (opt_dbg_autoload): New global variable.
(lisplib_try_load): Disable or enable debugging around
library loading based on opt_dbg_autoload option.
* lisplib.h (opt_dbg_autoload): Declared.
* txr.c (help): List --debug-autoload option.
(no_dbg_support): New static function to avoid repeated code.
(txr_main): Add debugger-autoload option. Change duplicate no debug
support error messages into calls to no_dbg_support.
* txr.1: Document --debug-autoload
2015-08-06 Kaz Kylheku <kaz@kylheku.com>
* txr.c (txr_main): Bugfix: debugger long option nonfunctional.
2015-08-06 Kaz Kylheku <kaz@kylheku.com>
Better diagnosis for loose @ forms.
* eval.c (op_meta_error): New static function.
(eval_init): Register sys:var and sys:expr as operators
that throw error.
* parser.y (sym_helper): Take parser_t instead of scanner_t
argument so we have access to the name and line number.
Obtain scanner internally from parser. Add source location
info to (sys:var ...) form.
(symhlpr): Retarget macro to pass parser rather than scanner to
sm_helper.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
New filesystem object testing functions.
* lisplib.c (path_test_set_entries, path_test_instantiate):
New static functions.
(dlt_register): Registered new functions to dl_table.
* txr.1: Documented new functions.
* share/txr/stdlib/path-test.tl: New file.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
Adding support for uid and gid manipulation.
* configure: Added check for geteuid and related functions.
* sysif.c (getuid_wrap, geteuid_wrap, getgid_wrap, getegid_wrap,
getgroups_wrap, setuid_wrap, seteuid_wrap, setgid_wrap, setegid_wrap):
New static functions.
(sysif_init): Register intrinsics getuid, geteuid, getgid,
getegid, getgroups, setuid, seteuid, setgid, setegid.
* txr.1: Documented new functions.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
* lib.c (system_error_s): New symbol variable.
(obj_init): Initialize new variable.
* lib.h (system_error_s): Declared.
* unwind.c (uw_init): Register system-error exception type.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
* stream.c (stream_init): Register get-indent-mode, set-indent-mode,
test-set-indent-mode, get-indent, set-indent, inc-indent
and width-check intrinsic functions. Register indent-off,
indent-data and indent-code variables.
* txr.1: Documented stream output indentation API.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
* stream.c (width_check): Just use the public
put_char function; no need to manipulate column
or call put_indent.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
Better diagnostic in funcall family of functions.
* lib.c (wrongargs): New static function.
(funcall, funcall2, funcall2, funcall3, funcall4):
Use wrongargs.
2015-08-05 Kaz Kylheku <kaz@kylheku.com>
* eval.c (do_eval): Bugfix: though last_form_evaled is
saved and restored around the execution of a special operator,
it is never set the current form.
2015-08-04 Kaz Kylheku <kaz@kylheku.com>
* eval.c (bind_args): Use new ~! for proper indentation
of multi-line context form.
(apply): Use ~! for proper indentation of function code.
* unwind.c (uw_throw): Use ~! for proper indentation of code.
2015-08-04 Kaz Kylheku <kaz@kylheku.com>
* stream.c (put_string): In indent mode, put_string has
to process all the characters as if by put_char,
(which we now do literally that way).
(set_indent_mode): Bugfix: no longer reset the column
to zero when turning off indent mode. This is wrong since
streams do column counting all the time.

Expand away sys:lisp1-value based on lexical info.
* eval.c (sys_lisp1_value_s): New global symbol variable.
(expand_lisp1_value): New static function.
(do_expand): Use expand_lisp1_value.
(eval_init): Initialize sys_lisp1_value_s.

Let's have placelet and placelet*.
* share/txr/stdlib/place.tl (placelet*): New macro.
* lisplib.c (place_set_entries): Add placelet* to list of names.
* txr.1: Updated to document placelet* and fix mistakes.
2015-07-11 Kaz Kylheku <kaz@kylheku.com>
* share/txr/stdlib/place.tl (defplace dwim): Eliminate
ogetter-sym variable for caching the sequence; use the getter
for the sequence place to access it. Again, this is for placelet,
where the caching is visible. Another way to fix this is to
clobber the cache variable when updating the sequence place.

* eval.c (eval_init): Register bindable as intrinsic.
* txr.1: Documented.

New placelet macro.
* lisplib.c (place_set_entries): Add placelet to list of names.
* share/txr/stdlib/place.tl (sys:placelet1, placelet): New macros.
(defplace dwim): Do not retrieve the
place's value into a local variable and have the getter
expand to that variable. Rather, have the getter retrieve the
value. A getter that refers to a cached copy breaks
the semantics of placelet, and any place operator which can
evaluate the location after it is stored.
* txr.1: Documented placelet.

Handle setting of parse name through prime_parser.
* parser.c (prime_parser): Take name as argument,
and install it into parser.
(lisp_parser): Pass name to parse, instead of setting it
in the parser object.
* parser.y (parse): Take name as argument and pass
down to prime_parser.
* parser.h (prime_parser, parse): Declarations updated.
2015-07-10 Kaz Kylheku <kaz@kylheku.com>
Fix wrong name reported for errors in first top-level form.
* parser.c (read_eval_stream): Get name of original stream,
and pass that down to lisp_parse as the name argument.
2015-07-10 Kaz Kylheku <kaz@kylheku.com>
Fix off by one error line numbers for .tl files.
* parser.c (read_eval_stream): Add terminating newline to
the first line that was examined for hash bang.
2015-07-10 Kaz Kylheku <kaz@kylheku.com>
Remove unused "primer" member from parser_t.
* parser.c (parser_mark, parser_common_init): Remove reference to primer.
