* Fix for uninitialized struct member curfiles in the match context.Kaz Kylheku2013-11-242-7/+20
| | | | | | | | | This is used for reporting the current match location in debug traces. * match.c (mf_all): Takes new argument curfiles and initializes the match_files_ctx member of the same name. (do_match_line, mf_from_ml, match_filter, match_fun, extract): Pass curfile to ml_all.
* * genvim.txr: Change how the hard-coded symbols (end, and, or) areKaz Kylheku2013-11-223-10/+17

* Nasty bug fixed: @(accept) from inside a @(collect) was found not toKaz Kylheku2013-11-212-6/+20
| | | | | | | | | | | | | propagate bindings. The culprit? The bindings_coll variable in the v_collect function being indeterminate by the well-documented and understood action of setjmp. Marking the bindings_coll variable volatile instantly fixed it. I reviewed this code to find any other instance of this oversight. * match.c (v_skip, v_collect): Mark some local variable volatile: precisely those which are used after possibly returning via an unwind, and which might have been modified since setting up the unwind block.
* * genvim.txr: Handle symbols whose C names end with _star_s,Kaz Kylheku2013-11-053-7/+18
| | | | | | and also ones with underscores. * txr.vim: Updated.
* * Makefile (clean): depends on conftest.cleanKaz Kylheku2013-10-283-3/+17
| | | | | | | | (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.

* Fix 2013-10-06 regression in op syntax. This happens when a @varKaz Kylheku2013-10-272-1/+14
| | | | | | | | | | syntax appears in an op form, crashing the expander with infinite recursion at program load time, before the code is run. * eval.c (transform_op): The fi == var check to handle a trailing op variable in the dot position of a form needs to ensure that it really is @<num> type var, and not the @<sym> type for instance.
* Fix jaw-dropping bug introduced on 2009-11-15, first affectingKaz Kylheku2013-10-271-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | the 022 release. Efficient string literal objects (tag bits 11) were introduced on that day. The null_string object was changed to a literal, and that object is efficiently returned by some string manipulation functions in cases when it is obvious that the result is an empty string. However, the LIT type code was not added to a switch statement in the variable matching code, which continued to recognize only the type STR as a string, to this day. A test case for this is echo ":x" | ./txr -c "@x:@x" - which results in an "unsupported object in spec" error. * match.c (h_var): Use stringp to test for string rather than type(..) == STR. Add LIT and LSTR to the switch statement so that literals an lazy strings are handled if they occur. (do_output_line): Add LIT and LSTR to switch.

* * genvim.txr: Include syntactic directives which aren't extracted fromKaz Kylheku2013-10-273-0/+9

* Ouch! Turns out the code base has numerous unintendedKaz Kylheku2013-10-247-25/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(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.
