* defstruct: new :inherit clause.Kaz Kylheku2022-10-171-0/+15
| | | | | | | | | | | | | | | The :inherit clause allows custom struct clauses to inject inherited bases. * stdlib/struct.tl (defstruct): Recognize :inherit clause, adding symbol arguments to extra list of supers that get appended to the list coming from defstruct's seconda rgument. (define-struct-clause): Disallow :inherit clause name. * tests/012/oop-dsc.tl: New tests. * txr.1: Documented.
* structs: optional init-exprs now useful in :delegateKaz Kylheku2022-10-111-2/+10
| | | | | | | | | | | | * stdlib/struct.tl (:delegate): Handle the two-element form of the optional parameter, which specifies the usual initializing expression for the default value. This is just passed through as-is to the generated method. Diagnose if the three-element form occurs. * tests/012/oop.tl: Some new tests. * txr.1: Documented.
* Syntax: allow separator commas in numeric tokens.Kaz Kylheku2022-10-051-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * parser.l (remove_char): New static function. (DIGSEP, XDIGSEP, NUMSEP, FLOSEP, XNUMSEP, ONUMSEP, BNUMSEP, ONUM, BNUM): New named lex patterns. (FLODOT): Use DIGSEP instead of DIG. (ONUM): Use ODIG instead of [0-7]. (BNUM): Use BDIG instead of [0-1]. (grammar): New rule for producing NUMBER from decimal token with commas based on BNUMSEP instead of BNUM. This is a copy and paste so that the BNUM rule doesn't deal with the comma removal, not to slow it down. For the octal, binary and hex, we just switch to BNUMSEP, ONUMSEP and XNUMSEP, so they all go through one case. Floating point numbers are also handled with a copy pasted case using FLOSEP. * tests/012/syntax.tl: New test cases. * txr.1: Documented. * genvim.txr (alpha-noe, digsep, hexsep, octsep, binsep): New variables. (txr_pnum, txr_xnum, txr_onum, txr_bnum, txr_num): Integrate separating commas. Some bugs fixed in txr_num, some simplifications, better txr_badnum pattern. * lex.yy.c.shipped: Updated.
* define-struct-clause: add tests.Kaz Kylheku2022-10-051-0/+65
| | | | * tets/012/oop-dsc.tl: New file.
* oop: allow multiple :init, :fini, etc.Kaz Kylheku2022-10-042-0/+28
| | | | | | | | | | | | | | | | | | | | | | The motivation is that struct clause macros defined using define-struct-clause may want to introduce their own initializers and finalizers for the specific stuff they add to the struct. The uniqueness restrictions on these initializing and finalizing clauses makes it impossible to use two clause macros which both want to inject a definition of the same initializer or finalizer type. * stdlib/struct.tl (defstruct): Don't enforce that there be at most one clause in the category of :init, :postinit, :fini or :postini. Multiple are allowed. They all execute left-to-right except for :fini. * tests/012/fini.tl: New tests. * tests/012/fini.expected: Updated. * txr.1: Documented.
* New :postfini feature in defstruct.Kaz Kylheku2022-09-272-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | The :postfini clause registers a finalizer that runs in the ordinary order: after previously registered ones. This has the effect of allowing a derived structure to run clean-up actions after those of inherited structures. Either order can be useful because the dependencies between base and derived can go in either direction. It's a huge mistake in C++ that it supports only derived-first destructor invocation order. * stdlib/struct.tl (defstruct): Recognize and translate :postfini clause. It's exactly like :fini but omits the t parameter in the finalize call, registering in the natural order. * tests/012/fini.tl (derived): Add :postfini handler. * tests/012/fini.expected: Updated to reflect the messages coming from the postfini handler, which are happening in the correct order. * txr.1: Documented.
* seq-iter: bugfix: floating-point ranges.Kaz Kylheku2022-09-151-0/+23
| | | | | | | | | | | | | | | | | | | | | | * lib.c (seq_iter_get_range_bignum): Static function renamed to seq_iter_get_range_number because it in fact generalizes to numbers. (seq_iter_peek_range_bignum): Renamed to seq_iter_peek_range_number. (seq_iter_get_rev_range_bignum): Renamed to seq_iter_get_rev_range_number. (seq_iter_peek_rev_range_bignum): Renamed to seq_iter_peek_rev_range_number. (si_range_bignum_ops): Renamed to si_range_number_ops. (si_rev_range_bignum_ops): Renamed to si_rev_range_number_ops. (seq_iter_init_with_info): Handle ranges where the from value is floating-point. Also, if the from-value is bignum that fits into cnum range, we now try to handle that as a cnum range. * tests/012/iter.tl: New tests.
* compiler: bug: scoping of lambda optionals.Kaz Kylheku2022-09-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | The scoping is not behind handled correctly for optional variables. The init-forms are being evaluated in a scope in which all the variables are already visible, instead of sequentially. Thus, for instance, variable rebinding doesn't work, as in (lambda (: (x x)) ...). When the argument is missing, x ends up with the value : because the expression refers to the new x, rather than the outer x. * stdlib/compiler.tl (compiler comp-lambda-impl): Perform the compilation of the init-forms earlier. Use the same new trick that is used for let*: the target for the code fragment is a locaton obtained from get-loc, which is then attached to a variable afterward. The spec-sub helper is extended with a loc parameter to help with this case. * tests/012/lambda.tl: New test case that fails without this fix.
* compiler: test for recent bugfix.Kaz Kylheku2022-09-141-0/+2
| | | | | | * tests/012/lambda.tl: Add the test case which reproduces the compiler failure that was fixed several commits ago.
* syntax: read and print [. x] and [. @x].Kaz Kylheku2022-09-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | * lib.c (obj_print_impl): Handle (dwim . atom) syntax by printing [. atom]. Note that (dwim . @var) and (dwim . @(expr)) already print as [. @var] and [. @(expr)]; this is not new. But none of these forms are supported by reading without the accompanying change to the parser. * parser.y (dwim): Handle the [. expr] and [ . expr] syntax, so that forms like [. a] and [. @a] have print-read consistency. The motivation is to be able to [. @args] in pattern matching to match a DWIM forms; I tried that and was surprised to have it blow up in my face. * tests/012/readprint.tl: New test file. Future printer/parser changes will be tested here. Historically, changes to the syntax have not been consistently unit-tested. * y.tab.c.shipped: Regenerated.
* New function: search-allKaz Kylheku2022-08-171-0/+15
| | | | | | | | | | | | | | | | | | | | | | | * eval.c (eval_init): search-all intrinsic registered. * lib.c (search_common): New Boolean argument all, indicating whether all positions are to be returned. We must handle this in the two places where empty key and sequence are handled, and also in the main loop. A trick is used: the found variable is now bound by list_collect_decl, but not used for collecting unless all is true. (search, rsearch, contains): Pass 0 for all argument of search_common. (search_all): New function. * lib.h (search_all): Declared. * tests/012/seq.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Regenerated.
* search/rsearch: some test cases.Kaz Kylheku2022-08-171-0/+36
| | | | * tests/012/seq.tl: New tests.
* New function: count.Kaz Kylheku2022-07-181-0/+10
| | | | | | | | | | | | | | | | The general count function, with keyfun and testfun, is noticeably absent. Let's implement it. * lib.[ch] (count): New function. * eval.c (eval_init): Register count intrinsic. * tests/012/seq.tl: Some tests for count. * txr.1: Add count to count-if section. Revise documentation based on pos/pos-if. * stdlib/doc-syms.tl: Updated.
* buf: compression tests.Kaz Kylheku2022-05-301-0/+18
| | | | | | | | | | * buf.c (buf_compress): Let's use the level value of -1 if not specified, so Zlib defaults it to 6, or whatever. * tests/012/buf.tl: New tests. * txr.1: Note that -1 is a valid level value and that is the default.
* utf8: bugfix: trailing char fragment ignored.Kaz Kylheku2022-05-201-0/+6
| | | | | | | | | | | | | | | | | | | | After "years of trouble-free operation" a bug in the UTF-8 decoder was found, which violates its property that any sequence of bytes will decode to some kind of string, which will encode to the original bytes. When the UTF-8 data prematurely ends in the middle of a valid character, the decoder just drops that data as if it didn't exist. So for instance the two-byte sequence E6 BC should decode to "\xDCE6\xDCBC", since it is a fragment of a three-byte UTF-8 sequence. It actually decodes to the empty string. * utf8.c (utf8_bfom_buffer): When the buffer is exhausted, if we are not in the utf8_init state, it means we were in the middle of a UTF-8 sequence. Walk the bytes from the backtrack point to the end of the buffer and store them into the string as U+DCxx codes. * tests/012/buf.tl: Tests added for this via buf-str, str-buf.
* opip: pass through forms in the op family.Kaz Kylheku2022-02-241-0/+6
| | | | | | | | | | | | | | * stdlib/op.tl (sys:opip-expand): Add op, do, lop, ldo, ap, ip, ado, ido, ret and aret to the operators whose forms are passed through untransformed. This is important because it lets us override the implicit (op ...) and (do ...) chosen by the expander. When a pipeline element produces a list, for instance, we want to be able to use (ap ...) in the next element to spread the list into arguments. * tests/012/op.tl: Add bellied numbers test case. * txr.1: Documented.
* New list-builder method: oust.Kaz Kylheku2022-02-231-0/+5
| | | | | | | | | | | | | | | | * autoload.c (build_set_entries): Add oust symbol. * stdlib/build.tl (list-builder postinit): Call the self argument self instead of bc, for consistency with other methods. (list-builder oust): New method. (list-builder-flets): Add local function oust. * tests/012/seq.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: partition-if.Kaz Kylheku2022-02-231-0/+26
| | | | | | | | | | | | | | | | * eval.c (eval_init): Register partition-if intrinsic. * lib.c (partition_if_countdown_funv, partition_if_func): New functions. (partition_if): New function. * lib.h (partition_if): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* find-max: convert to seq_info iteration.Kaz Kylheku2022-02-221-0/+13
| | | | | | | | | | | | * lib.c (find_max): Simplify into a single loop rather than handling various sequence types specially. This means it works for all iterable objects now. * txr.1: find-max documentation updated; discussion of hash tables removed, since the described behavior is the one expected for hash tables as iterables. * tests/012/seq.tl: Add some test coverage.
* typecase: merge with etypecase, handle t differnetly.Kaz Kylheku2022-01-212-1/+19
| | | | | | | | | | | | | | | | | * stdlib/type.tl (sys:typecase-expander): New function, formed from body of typecase. Bad clause syntax now handled with compile-error rather than (throwf 'eval-error). The t symbol is handled specially: it turns into a t conditon in the resulting cond rather than a typep test. The compiler will nicely eliminate dead code after that. Now etypecase is handled here also: if we are expanding etypecase, we just emit the extra clause. (typecase, etypecase): Reduced to sys:typecase-expander calls. * tests/012/typecase.tl: New file. * tests/012/compile.tl: Add type.tl to list of compile-tested files.
* testing: cover compiled, non-inlined lambda.Kaz Kylheku2022-01-141-13/+28
| | | | | | | | | | | | | | | | | | | The lambda.tl test, when compiled, is only testing the compiler's implementation of the inlined lambda: code generated from a lambda expression to which arguments are statically applied. We augment this to also compile real lambda functions which are called. Everything passes. * tests/012/lambda.tl (call-lambda): New function. (ltest): New macro, specifically geared for testing lambda expressions. When *compile-test* is true, this generates code which performs two tests: applying the arguments directly to the lambda, and evaluating the lambda to a function which is passed to call-lambda, which will then apply the arguments. We cannot use apply, because the compiler sees through that and will inline the lambda anyway. (mltest): Multi-expression version of ltest. This is a drop-in replacement for mtest in the rest of the file.
* new feature: :mass-delegate struct clause macro.Kaz Kylheku2021-12-231-0/+33
| | | | | | | | | | | | | | | With :mass-delegate, it is possible to generate delegation methods in bulk. All of the methods of a struct type can be mirrored by delegates in another struct type just by writing a single :mass-delegate clause. * stdlib/struct.tlk (:mass-delegate): New struct clause macro. * tests/012/oop.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* eval: fix optional parameter bug from 2014.Kaz Kylheku2021-12-231-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug affects optional parameters which either have no default expression, or one that is nil. For instance x in (lambda (: (x nil))) or (lambda (: x)). When such a parameter is given the : symbol as an argument, it is not being bound, as if it weren't there. ((lambda (: x) x) :) -> ;; error: unbound variable x This issue is not a regression; it was introduced in the commit which introduced the colon convention to optionals, as well as init expressions and presence-indicating variables, commit 68c084269581f32f0a7b859446ae2efb6c6a26c0 made in February 2014. This might be the first instance of an interpreter bug being found that is not present in the compiler. * eval.c (bind_args): The idea here was that when the argument to an optional the colon keyword symbol, and the optional's initform is nil, we can skip the overhead of calling eval to get that initform's value. Unfortunately, the skip was extended over the code which binds the parameter. Only the eval can be skipped! * tests/012/lambda.tl: New test cases to cover this.
* new feature: defstruct clause macros.Kaz Kylheku2021-12-221-0/+15
| | | | | | | | | | | | | | | | | | | | | | * lisplib.c (struct_set_entries): Trigger autoload on new symbols define-struct-clause and *struct-clause-expander*. * stdlib/struct.tl (*struct-clause-expander*): New variable. (defstruct): expand-slot local function now returns list of expanded slots, not a single slot; every case in the tree-case is converted to return a list. The syntax of a slot clause is first expanded through *struct-clause-expander hash; if that works then the resulting list is further scanned for expansions. (define-struct-clause): New macro. (:delegate): New struct clause defined with define-struct-clause. Provides single-slot delegation. * tests/012/oop.tl: Tests for :delegate. * txr.1: Documented define-struct-clause and :delegate. * stdlib/doc-syms.tl: Updated.
* The pairlis function comes to TXR Lisp.Kaz Kylheku2021-12-221-0/+8
| | | | | | | | | | | | * eval.c (eval_init): Register pairlis intrinsic. * lib.c, lib.h (pairlis): New function. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New functions: subq, subql, subqual and subst.Kaz Kylheku2021-12-221-0/+50
| | | | | | | | | | | | | | | * eval.c (eval_init): Register new intrinsics. * lib.c, lib.h (subq, subql, subqual, subst): New functions. * tests/012/seq.tl: New test cases. * stdlib/optimize.tl (subst): Function removed. The new subst drop-in replaces this one. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* less: bug, vectors not supported.Kaz Kylheku2021-12-201-0/+21
| | | | | | | | * lib.c (less_tab_init): Add missing initialization for VEC, with a priority above CONS: all vectors are greater than conses. The BUF priority is bumped to 7. * test/012/less.tl: New file.
* define-accessor: fix broken arg handling.Kaz Kylheku2021-12-101-0/+12
| | | | | | | | | | | I discovered this off chance by searching for occurrences of (let ,(zip ...) ...) or (let (,*(zip ...)) ...) in the code base, noticing an incorrect one. * stdlib/place.tl (sys:register-simple-accessor): Remove spurious list around ,(zip temps args). * tests/012/defset.tl: Test cases for define-accessor added.
* case macros: bug in singleton key optimization.Kaz Kylheku2021-12-081-0/+32
| | | | | | | | | | | | * eval.c (me_case): Reduce (key) to key only if key is an atom. Otherwise we reduce ((a b c)), which is a single list-valued key to (a b c), which looks like three keys. This was introduced on Oct 25, 2017 in commit b72c9309c8d8f1af320dce616a69412510531b48, making it a regression. * tests/012/case.tl: New file. The last test case fails without this bugfix. The others pass either way.
* rot, nrot: new functions.Kaz Kylheku2021-12-071-0/+78
| | | | | | | | | | | | | | * eval.c (eval_init): nrot, rot intrinsics registered. * lib.c (nrot, rot): New functions. * lib.h (nrot, rot): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* tuples*: new function.Kaz Kylheku2021-12-041-0/+47
| | | | | | | | | | | | | | | * eval.c (eval_init): Register tuples* intrinsic. * lib.c (tuples_star_func): New static function. (tuples_star): New function. * lib.h (tuples_star): Declared. * tests/012/seq.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* tuples: add test cases.Kaz Kylheku2021-12-021-1/+48
| | | | * tests/012/seq.tl: Numerous test cases for tuples.
* tuples: check length argument.Kaz Kylheku2021-12-021-0/+3
| | | | | | | * lib.c (tuples): Check that n argument giving tuple size is a is a positive integer. * tests/012/seql.tl: Test case added.
* syntax: add tests for #; syntax.Kaz Kylheku2021-10-231-0/+12
| | | | * tests/012/syntax.tl: New tests, some of which fail.
* printer: bug: fallback syms printed without prefix.Kaz Kylheku2021-10-123-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a basic read/print consistency problem. When a symbol is printed that is anywhere in the fallback list of the current package, we are dumping it unqualified, even if it is hidden by a same-named symbol in the current package itself or such a symbol occurring earlier in the fallback list. * lib.c (symbol_needs_prefix): When the to-be-printed symbol is found in the fallback list, re-scan the current package for a symbol having the same name, as well as the preceding nodes in the fallback list. If such a symbol is found, then the to-be printed symbol must be package-qualified. * tests/012/syms.expected: New file. * tests/012/syms.tl: Likewise. * tests/012/compile.tl: Pull syms into compile job. * txr.1: Clarify text about this. The existing text's only reasonable interpretation supports the behavior which this patch ensures (which is needed on grounds of read/print consistency) but the text lacks precision.
* seq_iter: some new test cases.Kaz Kylheku2021-08-301-0/+8
| | | | | * tests/012/iter.tl: Several new cases to provide some coverage in recently fixed areas. All of these break in 268.
* sub: allow generic iterables.Kaz Kylheku2021-08-221-0/+19
| | | | | | | | | | | | | | | | In this patch we allow the s in (sub s from to) and [s from..to] to be any iterable. * lib.c (iter_dynamic, sub_iter): New static function. (generic_funcall): Handle all objects via the sequence case: ref, sub and all that. Unfortunately, we lose some error handling at the level of the sub function. But we allow any iterable to be passed through to sub. (sub): Handle default case through sub_iter. * tests/012/iter.tl: New cases. * txr.1: Documented.
* iter-begin: string range support.Kaz Kylheku2021-08-221-0/+42
| | | | | | | | | | | | | | Ranges like "AAA".."ZZZ" are now possible. * lib.c (seq_iter_get_range_str, seq_iter_peek_range_str, seq_iter_get_rev_range_str): New static functions. (seq_iter_init_with_info): Support string ranges via above new functions. Range direction test is now done with less and equal rather than lt and gt. * tests/012/iter.tl: New file. * txr.1: Documented.
* windows: skip test requiring full Unicode.Kaz Kylheku2021-08-071-0/+3
| | | | | * tests/012/cont.tl: Exit before the test case that contains characters ouside of the BMP, if (sizeof wchar) is less than 4.
* tests: fix undefined variable warning.Kaz Kylheku2021-08-031-1/+3
| | | | | * tests/012/oop.tl: Adjust one recently added test case to eliminate undefined variable warning.
* oop: fix infelicity in new* and lnew* macros.Kaz Kylheku2021-07-311-0/+14
| | | | | | | | | | * stdlib/struct.tl (sys:new-expander): If the argument of new* or lnew* is dwim, then treat that as an expression, rather than as a boa-style construction. * tests/012/oop.tl: Tests for new* focusing on this issue. * txr.1: Documented.
* tests: multiple evaluation issue in amb.Kaz Kylheku2021-07-301-2/+2
| | | | | | | | | | | | | | | | This issue doesn't affect the tests. This is for the benefit of someone who happens to be copy-and-pasting the amb implementation from here. * tests/012/cont.tl (amb): This function has an issue in that it calls the continuation (future calculation) and then if that succeeds, it normally returns the value. This means that the future is executed again. In the case of N amb expressions, the successful future is executed 2**N times. What amb must do is this: call the continuation and capture the value. If the value is successful, then that is the master return value; just return that from amb-scope, bypassing the second re-execution of the future.
* tests: longer test for delimited continuations.Kaz Kylheku2021-07-301-0/+10
| | | | | * tests/012/cont.tl: New test case. This aborts prior to recent gc fixes.
* subtypep: handle struct type objects.Kaz Kylheku2021-07-271-0/+48
| | | | | | | | | | | | | The subtypep function has poor requirements, handling only type symbols. Let's extend it to handle structure type objects. * lib.c (subtypep): In all cases when an argument is considered to be a possible structure symbol, and thus subject to find_struct_type, consider whether it already is a struct type, and just take it as-is. * tests/012/type.tl: New tests. * txr.1: Updated.
* op: set nested flag in correct context.Kaz Kylheku2021-07-191-0/+11
| | | | | | | | | | | | * stdlib/op.tl (sys:op-meta-p): Return an extended Boolean value: a true result is an integer indicating the depth of the variable. For instance @1 is depth 0, @@1 is depth 1 and so on. (sys:find-parent): New function. (sys:op-alpha-rename): When processing a nested meta, do not set the nested flag in the immediate parent. Use find-parent to go up to the correct level to which the meta belongs and set the flag there. * tests/012/op.tl: New test cases which depend on this.
* op: fix bug in do.Kaz Kylheku2021-07-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The June 30 09e70c914ca83b5c7405aa633864db49f27efa05, subject "op: refactor do handling", introduced a regression breaking the tags.tl program. An implicit argument gets inserted twice: [[(do op list @1)] 'x] -> (x x) ;; incorrect/weird This was spotted by Paul A. Patience while working on extending tags.tl for Emacs. It's not exactly a regression because the original behavior is not documented or tested, and has issues; we simply cannot roll back the commit; a proper fix is required. How the above call is now supposed to work is that: - the @1 parameter belongs to the op, not to the do. - the do therefore has no explicitly given parameters of its own. - therefore the do inserts its parameter. In other words (do op list @1) is formally equivalent to (do op list @1 @@1). Both levels of function indirection require an argument: [[(do op list @1) 'x] 'y] -> (y x) [[(do op list @1 @@1) 'x] 'y] -> (y x) * stdlib/op.tl (sys:op-ctx): The structure gets a new slot, nested, which is a flag indicating whether unprocessed nested metas occur. This is critically needed because the sys:op-alpha-rename passes which are called with do-nested-metas being false do not insert nested metas into the gens list; they transform them and leave them in the syntax. Yet we must make decisions based on their presence. Conretely, we must be able to tell that (do op list @@1) has a meta against the outer (do ...), while we are just processing the do. (sys:op-alpha-rename): When replacing a nested meta syntax with the macro invocation, we set the nested flag of the parent context true. (sys:op-expand): Bring back the do-gen; we need it. We cannot simply insert @1 into the syntax, because that is not lexically transparent. If we add @1 to (do op ...) then that @1 is interpreted as belonging to the op, not to the do. We must also check the new Boolean flag nested to properly detect whether we have metas, including unexpanded nested metas. * tests/012/op.tl: New test cases combining (do op ...).
* tests: fix stack overflow test case for old gmake.Kaz Kylheku2021-07-141-2/+7
| | | | | | | | | | | | | | | * tests/012/stack.tl: The (if stack-limited ...) test is not correct because even if gerlimit indicates an unlimited stack, we impose a defualt limit, and so (get-stack-limit) returns a an integer value. The idea here was to try to skip this test case when the stack usage is unlmited, which happens under older versions of GNU make, before posix_spawn was introduced. Instead, let's execute this test case only if we have setrlimit. In the forked child, we try to impose a small stack limit that will give use the stack overflow crash we are testing for. The objective of the test case is to validate that when (set-stack-limit 0) is called, the child will abort due to a signal, rather than (recur) returning :so.
* lib: tests for keep-if, remove-if, separate.Kaz Kylheku2021-07-101-0/+42
| | | | * tests/012/seq.tl: New tests.
* subtypep: handle COBJ inheritance.Kaz Kylheku2021-07-091-0/+20
| | | | | | | | | | | | | | | | | | * lib.c (class_from_sym): New static function. (subtypep): Remove special case handling of stream versus stdio-stream. If the two types are not both structures, then check whether they are both cobj classes. If so, check if they are in an inheritance relationship via the cobj_hash. (cobj_populate_hash): Map each symbol to a fixnum integer which gives class handle'position in the cobj_class table. (cobj_class_exists): Style: compare to nil instead of 0. (obj_init): Do not call cobj_populate_hash here, it is far too early: only a couple of COBJ types exist at this point. Moreover, hash_init has not been called so hash_cls and hash_iter_cls still have null symbols. (init): Call obj_populate_hash here, as the last step. * tests/012/type.tl: New file.
* with-resources: undocumented nil skip behavior.Kaz Kylheku2021-07-071-0/+18
| | | | | | | | | | | | | | | Paul A. Patience discovered the hidden "feature" of with-resourcers, that the three-argument form of the binding (var init cleanup) causes the with-resources form to terminate if init returns nil. The (var init) syntax doesn't generate this logic. * stdlib/with-resources.tl (with-resources): Do not emit the when form unless <= 265 compatibility is in effect. * tests/012/oop-mac.tl: New file. * txr.1: Compat note added.
