* Bug #34652Kaz Kylheku2012-02-251-0/+10
| | | | | | | | * match.c (do_txeval): Establish a dynamic env frame around evaluation of quasiliteral and around embedded TXR Lisp expression (which may contain quasiliterals) and stick the bindings there via set_match_context. This way if filte functions are invoked through a quasiliteral, they can see bindings.
* * eval.c (eval_init): New put-byte function interned.Kaz Kylheku2012-02-251-0/+12
| | | | | | | | | | * stream.c (struct strm_ops): New member, put_byte. (stdio_put_byte): New function. (stdio_ops, pipe_ops, string_in_ops, byte_in_ops, string_out_ops, strlist_out_ops, dir_ops): Updated. (put_byte): New function. * stream.h (put_byte): Declared.
* * parser.l (num_esc): Skip octal indicator 'o' if present.Kaz Kylheku2012-02-251-0/+8
| | | | | | | This is needed for character constants. (CHRLIT): Fix broken hex constants, being treated as octal. * txr.1: Document octal character constants.

| | | | | | | | | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated. * eval.c (eval_init): Updated. * rand.c (rand): Function renamed to rnd due to a clash with standard C library (that does not show up when compiling as C++). * rand.h (rand): Declaration renamed to rnd.
* * parser.l (source_loc_str): Missing function re-written.Kaz Kylheku2012-02-251-0/+9
| | | | | | | | (Accidentally originally written in lex.yy.c file!) (parse_reset): If file can't be opened, try adding .txr suffix to it. * txr.1: Suffix-handling behavior documented.
* * parser.y (clause): "Doh" moment. We don't need the specialKaz Kylheku2012-02-251-0/+9
| | | | | | | | transformation of the load syntax because the parent location is already associated with the syntax. * match.c (v_load): Pull out source location info from the form itself.
* * debug.c (debug): Use new way of getting line number.Kaz Kylheku2012-02-241-0/+16
| | | | | | | | | | | | | | * eval.c (eval_error): Use source_loc_str to get source location. * match.c (debuglf, sem_err, file_err): Likewise. * parser.h (source_loc_str): Declared. * parser.l (parse_init): form_to_ln_hash must be equal based now. * parser.y (rl): Store new form of read-time source location info. * txr.1: Documented load.
* * match.c (v_load): Sanity checking on target path.Kaz Kylheku2012-02-241-0/+6
| | | | | Check if it is absolute and do not substitute parent file's directory.
* * match.c (h_var): Eliminated uses of rl function, in favor ofKaz Kylheku2012-02-241-0/+5
| | | | rlcp. Only the parser should use rl to establish location info.
* First cut at @(load) directive. Incomplete: debug location infoKaz Kylheku2012-02-241-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | needs to record file name, not only line number; absolute paths not handled, etc. * match.c (load_s): New symbol variable. (v_load): New static function. (syms_init): load_s initialized. (dir_tables_init): Load directive registered. * match.h (load_s): Declared. * parser.h (parse_reset): New function declared. * parser.l (spec_file_str): Global variable moved from txr.c. (parse_reset): New function. * parser.y (clause): Special handling for @(load ...) directive. parent file path inserted into the syntax at parse time, so when the load directive executes, it can load the file from the same directory as the parent file. * txr.c (spec_file_str): Global variable moved to parser.l.
* * tests/010/seq.txr: New file.Kaz Kylheku2012-02-221-0/+6
| | | | * tests/010/seq.expected: New file.
* * lib.c (sub_list, replace_list, lazy_sub_str, sub_str,Kaz Kylheku2012-02-221-0/+10
| | | | | | | | | replace_str, sub_vec, replace_vec): Implementing floating zero behavior. This is necessary so that the important case index .. (+ index 1) for selecting one element as a subrange works even if index is negative. * txr.1: Floating zero behavior for ranges documented.
* * eval.c (dwim_loc): del operator's return value is theKaz Kylheku2012-02-221-0/+9
| | | | | | | | deleted range of values. Missing del cases added for single index cases. * lib.c (quicksort): Fix pivot selection one more time. (length): Fix bad argument in "not a sequence" error.
* * lib.c (quicksort): Incorrect pivot selection.Kaz Kylheku2012-02-221-0/+4
|
* * eval.c (del_s): New symbol variable.Kaz Kylheku2012-02-221-0/+20
| | | | | | | | | | | | | | | | | | | (eval_error): nostatic added to suppress a g++ warning. (dwim_loc): Takes new value as the original unevaluated form so it can control evaluation. Support for del operator added. (op_modplace): Bugfixes: new value form was being unconditionally evaluated and out of order w.r.t. other forms. Now there is left to right order. The form is evaluated later, since for most operators it is on the right, with the exception of push. dwim places can now optionally control the evaluation of newform. del operator supported in gethash case as a special case. error case added for del: if it's not handled in gethash or dwim_loc, it is an error. (eval_init): del_s initialized, and del operator added to table. * txr.vim: syntax highlighting for del. * txr.1: Documented del.
* * lib.c (init): Hash bugfix: added missing call to hash_init.Kaz Kylheku2012-02-221-0/+6
| | | | | Previously this function did nothing, but now it interns some important symbols.
* * hash.c (remhash): Rewrote buggy function.Kaz Kylheku2012-02-221-0/+8
| | | | | | | It was decrementing the hash count without checking that something was deleted from the chain. The deletion was done incorrectly, without regard for the kind of comparison fucntion used by the hash table.
* * eval.c (eval_init): Intrinsic bindings for sub, ref, refsetKaz Kylheku2012-02-221-0/+17
| | | | | | | | | | | | | | | | and replace. * lib.c (do_sort): Static function renamed to sort_list. (swap, quicksort, sort_vec): New static functions. (sort): Made generic over lists, vectors and strings. (refset): New function. * lib.h (sort): Declaration updated (parameter name change). (refset): Declared. * txr.1: Mention refset. * txr.vim: Updated with refset.

(func_n0o, func_n1o, func_n2o, func_n3o, func_n4o): New functions. (cobj_print_op): Reversed arguments to put_string. (find): testfun and keyfun become optional arguments. (replace): Parameters rearranged and arguments rearranged in calls to replace_list, replace_str and replace_vec. (obj_init): colon_k initialized. (obj_print, obj_pprint): Arguments reversed, and stream defaults to std_output. Arguments reversed in calls to put_char and put_string. (dump): Arguments reversed in call to put_char. * lib.h (struct func): sizes of minparam, fixparam bitfields adjusted. New bitfield optargs. New unnamed bitfield added so the previous ones add up to 16 bits. (colon_k): Declared. (func_n0o, func_n1o, func_n2o, func_n3o, func_n4o): Declared. (replace_list, replace_str, replace_vec, replace): Declarations updated. * match.c (debuglf, dump_shell_string, dump_byte_string, dump_var, do_output_line, extract): Reversed arguments to put_char and

| | | | | variables. Lists do not have to be wrapped in @(repeat)/@(rep). Indexing notation works on strings and vectors.
* * lib.c (sub, ref, replace): New functions.Kaz Kylheku2012-02-191-0/+12
| | | | | | | | | | * lib.h (sub, ref, replace): Declared. * match.c (format_field): Generic indexing using new functions. * txr.1: Documentation stub. * txr.vim: Highlighting for new functions.
* * match.c (extract_vars): If a brace var is actually anKaz Kylheku2012-02-181-0/+7
| | | | | | expression, then recurse into the expression to find variables. This allows us to do things like @{`@x`} inside a @(repeat) or @(rep).
* Allow braced output variables to actually be arbitrary substitutions.Kaz Kylheku2012-02-181-0/+16
| | | | | | | | | | | | | | * eval.c (subst_vars): Treat the variable as an arbitrary expression rather than just a symbol. * match.c (subst_vars): Likewise. * parser.y (o_var): Further simplification. The first item in an output var is an expr and not an IDENT. * txr.1: Updated. * txr.vim: Likewise.
* * parser.y (o_var): Remove productions from grammar by using exprs_opt.Kaz Kylheku2012-02-181-0/+4

* Reimplementation of how TXR decides whether to dump bindingsKaz Kylheku2012-02-171-0/+16
| | | | | | | | | | | | | | | or not. This is now done right inside the standard output stream. * match.c (output_produced): Variable removed. (complex_open): Assignment to output_produced removed. * stream.c (output_produced): New global variable. (stdio_put_string, stdio_put_char): Set output_produced to t if the target of the output is stdout. * stream.h (output_produced): Declared. * txr.h (output_produced): Declaration removed.
* * eval.c (dwim_loc): 2012-02-13 fix didn't do it.Kaz Kylheku2012-02-171-0/+6
| | | | | Here is a simpler way. We can let nil be treated as a list with a simple goto. This solves all cases.
* * eval.c (eval_init): Register match-fun.Kaz Kylheku2012-02-161-0/+17
| | | | | | | | | | | | | | | * match.c (v_do): Store match context. (match_fun): New function. * match.h (match_fun): Declared. * stream.c (streamp): New function. * stream.h (streamp): Declared. * txr.1: Stub section for match-fun. * txr.vim: Highlight match-fun.

| | | | | | * match.h (match_funcall): Declaration updated. * filter.c (get_filter): Updated.
* * eval.c (op_catch): Treat the nil exception object as an emptyKaz Kylheku2012-02-161-0/+10
| | | | | | | | | list, and not the atom nil. * match.c (v_try): Do not transform an atomic exception x into the list ((t . x)). Just to (x). This (t . x) representation is a vestige of from the time when the exception consisted of the old-style return values from txeval.
* TXR Lisp gets exception handling.Kaz Kylheku2012-02-161-0/+19
| | | | | | | | | | | | | | | | | * eval.c (op_catch, expand_catch_clause, expand_catch): New static functions. (expand): Handle catch operator. (eval_init): Added catch operator to op_table, and registered new functions throw, throwf and error. * txr.1: Documented catch operator and created stub section for throw, throwf and error. * txr.vim: Updated. * unwind.c (uw_throwfv, uw_errorfv): New functions. * unwind.h (uw_throwfv, uw_errorfv): Declared.
* * eval.c (rangev_func, rangev, range_star_v_func,Kaz Kylheku2012-02-141-0/+6
| | | | | range_star_v): Regression: handle the case where the range is open-ended (to is nil).
* * eval.c (rangev): If a descending range is specified,Kaz Kylheku2012-02-141-0/+12
| | | | | | | | | | | but the step is omitted, the step should be negative one rather than one. (range_star_v_func, range_star_v): New static functions. (eval_init): New function, range*, registered. * txr.1: Stub section for range is also for range*. * txr.vim: Recognize range* function.
* * eval.c (rangev_func): Improved termination test. The sequenceKaz Kylheku2012-02-141-0/+5
| | | | not only if it achieves the endpoint, but if it crosses it.
* * eval.c (dwim_loc): Allow assignment to the dwim place when itKaz Kylheku2012-02-131-0/+7
| | | | | | evaluates to nil, by building a form targetting the place, and recursing into op_modplace. Also, optimization: don't use eval on a form built from the operator; just go to op_modplace directly.
* Version 57txr-57Kaz Kylheku2012-02-131-0/+12
| | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version and set date. * configure (txr_ver): Bumped. * RELNOTES: Updated.
* * eval.c (subst_vars): Handle lone symbols (not wrappedKaz Kylheku2012-02-131-0/+13
| | | | | | | | | | | | in sys::var form) as variables. This allows interpretation of metanums in quasiliterals, because these are replaced by variables in the op expander. * parser.l: Recognize METANUM in QSILIT state. * parser.y (quasi_item): METANUM parsed in quasiliteral. * txr.vim: Metanums highlighted properly.
* * eval.c (dwim_loc, op_dwim): Bugfix: hash indexing requiringKaz Kylheku2012-02-131-0/+5
| | | | at least two arguments, rather than at least one.
* * HACKING: Added note about register save areas, which can contributeKaz Kylheku2012-02-121-0/+5
| | | | to spurious retention.
* * debug.c (breakpoints, last_command): linkage changed to static.Kaz Kylheku2012-02-121-0/+8
| | | | | | | (cols): New static variable. (debug): Print context intelligently, fitting into the width of the screen. (debug_init): Try to get terminal width, from the COLUMNS variable.
* * lib.c (lazy_flatten): Bugfix: function was assuming thatKaz Kylheku2012-02-121-0/+7
| | | | | | the input is a list, and not handling the case atom -> (atom) like its non-lazy counterpart. This broke @(next :list expr).
* * lib.c (obj_print): Print control characters in string andKaz Kylheku2012-02-121-0/+18
| | | | | | | | | | | | | | | | | character literals as hex escapes, followed by semicolon if necessary. Don't use iswprint function since it is locale-specific and concludes that non-ASCII characters are unprintable. Changed print syntax for lazy strings. (obj_pprint): Changed print syntax for lazy strings. * parser.l: Bugfix in hex/octal character constant. num_esc(yytext) was called rather than num_esc(yytext+1). * parser.y (chrlit): Bugfix: missing case for hex and octal constants which are given by a LITCHAR token. * stream.c (vformat): Bugfix: strings were being printed as if using ~a even under ~s.
* Task #11486Kaz Kylheku2012-02-121-0/+6

| | | | | | | | | | | | | | | | | | | | a large file horizontally under @(freeform) in constant memory. Position reporting is incorrect. * match.c (match_line_ctx): New member, base. (ml_all): Initialize new member to zero. (consume_prefix): New static function. (do_match_line): New static function, contains implementation of match_line. Calls consume_prefix. (match_line): Becomes a wrapper for do_match_line. (search_form, h_skip): Call consume_prefix. (freeform_prepare): New function. External to avoid inlining. (v_freeform): Uses do_match_line, to down context by reference, and also refactored to avoid spurious retention of c->data. * unwind.c (uw_push-block, uw_push_env, uw_push_debug, uw_push_catch): Zero out the structure, otherwise the unused fields can cause spurious retention.
* Task #11486: preparatory refactoring.Kaz Kylheku2012-02-091-0/+13
| | | | | | | | | | | * match.c (h_match_func): Changed to one-argument form. (LOG_MISMATCH, LOG_MATCH): References to structure members changed from member selection . to ->. (h_text, h_var, h_skip, h_coll, h_parallel, h_trailer, h_fun, hv_trampoline, h_define, h_do): Changed to one-argument form that takes a pointer to the context. (match_line): Local pointer named c used so that the LOG_MISMATCH and LOG_MATCH macros can be used.
* * lib.c (lazy_sub_str): New static function.Kaz Kylheku2012-02-091-0/+8
| | | | | | | (sub_str): Bugfix: handle t values of from from and to, and negative indices, just like sub_vec. Special handling for lazy strings introduced. If to is the value t, then the a lazy string can be produced.
* * genman.txr: Updated.txr-56Kaz Kylheku2012-02-051-0/+8
| | | | | | * txr.vim: Fixed mistakes in a few regex character classes, causing upper case letters not to be recognized as part of a variable name, and character hex constant.
