* getopts: forbid :bool in list/cumul types.Paul A. Patience2022-02-121-0/+2
| | | | | | | * stdlib/getopts.tl (list-type-p): Return nil if subtype is :bool. (cumul-type-p): Same. * txr.1: Documented, reworded some sentences, fixed some typos.
* macro-time: special op becomes a macro.Kaz Kylheku2022-02-121-1/+1
| | | | | | | | | | | | | * eval.c (me_macro_time): New static function (do_expand): Remove handling of macro_time_s. (eval_init): Remove special operator registration of macro-time; add macro registration. * txr.1: Documentation of macro-time updated, revised and moved from the top the Macros section to be adjacent to equot. * stdlib/doc-syms.tl: Updated.
* matcher: fix `@{nil #/regex/}` throwing exception.Paul A. Patience2022-02-091-2/+5
| | | | | | * stdlib/match.tl (expand-quasi-match): We cannot call m^$ with the @nil-bound rest of string when matching `@{nil #/regex/}`. Handle this case specially.
* getopts: fix superfluous options header.Paul A. Patience2022-02-081-24/+26
| | | | | * stdlib/getopts.tl (opthelp): Print the options header only if we have documented options.
* getopts: fix de trop descriptions of conventions.Paul A. Patience2022-02-081-18/+20
| | | | | | * stdlib/getopts.tl (opthelp-conventions): Describe the --no- prefix only if we have boolean options, and describe the long-option argument style only if we have long options.
* getopts: conform undocumented opts to documented.Paul A. Patience2022-02-081-2/+2
| | | | | | * stdlib/getopts.tl (opthelp): Indent the list of undocumented options by only two spaces, like the documented options and the other opthelp sections.
* getopts: uniformize opthelp newlines and headers.Paul A. Patience2022-02-081-3/+5
| | | | | | | | | | | | | | | | The documented options and type legend both end in a blank line, unlike the undocumented options and option conventions. * stdlib/getopts.tl (opthelp): Print a blank line after the undocumented options. (opthelp-conventions): Print a blank line after the conventions. Also, change the header from "Option Conventions" to "Option conventions" to follow the style of the undocumented options and type legend. * txr.1: Remove superfluous (as of now) put-line calls in the --extra-help example of getopts. While here, correct o.extrahelp to o.extra-help.
* doc: fix various typos and stylistic issues.Paul A. Patience2022-02-061-9/+9
| | | | | | * txr.1: Fix typos and stylistic issues. * stdlib/doc-syms.tl: Updated.
* getopt: opthelp: bind *stdout* to remove stream repetition.Kaz Kylheku2022-02-041-15/+15
| | | | | | | * stdlib/getopts.tl (opthelp, opthelp-conventions, opthelp-types): Use *stdout* as the optional stream argument, defaulting to *stdout*. Now we no longer have to explicitly pass the stream to put-line.
* matcher: bug: quasiliteral allowing prefix matches.Kaz Kylheku2022-02-041-3/+4
| | | | | | | | * stdlib/match.tl (expand-quasi-match): When matching `text` or `@var`, which are matching in the final position of the specimen, it is not good enough that match-str returns true; we must check that the entire string was matched. Reported by Paul A. Patience.
* getopts: break up help into three functions.Kaz Kylheku2022-02-032-71/+81
| | | | | | | | | | | | | | | | * lisplib.c (getopts_set_entries): Autoload for opthelp-conventions and opthelp-types. * stdlib/getopts.tl (opthelp): Remove incnotes parameter. Entirely trim out the code for notes about conventions and use of types. (opthel-conventions, opthelp-types): New functions. (option-base opthelp-conventions, option-base opthelp-types): New methods. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* getopts: make detailed help notes optional.Joe Bloggs2022-02-031-67/+68
| | | | | | | | | | * stdlib/getopts.tl (opthelp): New incnotes parameter. If specified as false, disables the detailed Notes and Type legend. (sys:option-base opthelp): Same new parameter on this method, passed down to opthelp. * txr.1: Documented.
* quip: joke about dark mode.Kaz Kylheku2022-02-031-0/+1
| | | | * quips.tl (%quips%): New one.
* getopts: fix display of overlong-option help text.Paul A. Patience2022-02-021-1/+3
| | | | | | | | * stdlib/getopts.tl (opthelp): If the long/short part of an option description is 34 characters long or more, print the help text starting on the next line, lest it be glued to the long/short part (i.e., without an intervening space) and extend too far to the right.
* getopts: fix ignored stream parameter in opthelp.Paul A. Patience2022-02-021-14/+13
| | | | | * stdlib/getopts.tl (opthelp): Actually use the function's stream parameter in the put-line calls.
* cadr: re-running gencadr.txr.Kaz Kylheku2022-01-301-12/+13
| | | | | | | * cadr.c, cadr.h, stdlib/cadr.tl: Regenerated. All that changes is the formatting of the copyright block, since now it is scraped from files that reformatted it to 80 columns half a year ago.
* conv: extra blank line removed.Kaz Kylheku2022-01-301-1/+0
| | | | | * stdlib/conv.tl: Extra blank line after copyright header removed.
* stdlib: missing blank line after copyright header.Kaz Kylheku2022-01-3036-0/+36
| | | | | | | | | | | | | | | Commit 93edcde038209335122964432bd35dee0c2ecb04, made in August 2021, accidentally removed the blank line after the copyright header in most stdlib files. stdlib{asm.tl, awk.tl, build.tl, compiler.tl, copy-file.tl, debugger.tl, doloop.tl, each-prod.tl, error.tl, except.tl, ffi.tl, getopts.tl, getput.tl, hash.tl, ifa.tl, match.tl, op.tl, package.tl, param.tl, path-test.tl, pic.tl, place.tl, pmac.tl, quips.tl, save-exe.tl, socket.tl, stream-wrap.tl, tagbody.tl, termios.tl, trace.tl, txr-case.tl, type.tl, vm-param.tl, with-resources.tl, with-stream.tl, yield.tl}: Ensure there is a blank line after the copyright header.
* New function: random-sample.Kaz Kylheku2022-01-291-2/+3
| | | | | | | | | | | | | | | | Implements reservoir sampling. * rand.c (radom_float_impl): New static function, made out of random_float. Returns double, giving us access to the unboxed result (random_float): Now a wrapper around random_float_impl: boxes the result of random_float. (elrd, flrd, random_sample): New static functions. (rand_init): Register random-sample intrinsic. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: copy-cptr.Kaz Kylheku2022-01-281-0/+1
| | | | | | | | | | | | | | | * eval.c (eval_init): copy-cptr intrinsic registered. * lib.c (copy_cptr): New function. (copy): Use copy_cptr for CPTR objects. * lib.h (copy_cptr): Declared. * tests/017/ffi-misc.tl: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* quips: new entry.Kaz Kylheku2022-01-251-0/+1
| | | | % stdlib/quips.tl (%quips%): New one.
* lib: new functions nand, nor, nandf and norf.Paul A. Patience2022-01-221-0/+4
| | | | | | | | | | | | | | * eval.c (me_nand, me_nor, nor_fun, nand_fun): New functions. (eval_init): Register new intrinsics. * lib.c (nandv, norv): New functions. * lib.h (nandv, norv): Declared. * txr.1: Documented, along with trivial fixes to the descriptions of and, or, andf, orf and notf. * stdlib/doc-syms.tl: Updated.
* compiler: optimize some typep expressions.Kaz Kylheku2022-01-211-0/+12
| | | | | | | | * stdlib/compiler.tl (compiler compile): Handle typep symbol via comp-typep method. (compiler comp-typep): New method. This recognizes some absolute truths: every object is of type t, and no object is of type nil.
* typecase: merge with etypecase, handle t differnetly.Kaz Kylheku2022-01-211-19/+21
| | | | | | | | | | | | | | | | | * 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.
* type: new macro etypecase.Paul A. Patience2022-01-212-0/+12
| | | | | | | | | | * lisplib.c (type_set_entries): Add etypecase to autoload list. * stdlib/type.tl (etypecase): New macro. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: few more cases of ifq/ifql removal.Kaz Kylheku2022-01-181-1/+10
| | | | | | | | | | * optimize.tl (basic-blocks peephole-block): Check for the reversed arguments case of (ifq (d x) (t 0)), and also match ifq. Add a case for two different d registers being compared by ifq or ifql which are not both implicated as load-time regs; that also converts to an unconditional jmp to the else label. Add a case for a register being compared with itself with ifq or ifql, which disappears.
* New function: match-fboundp.Kaz Kylheku2022-01-171-0/+1
| | | | | | | | | | | | | | | | | | User vapnik spaknik was asking in the mailing list whether there is an existence test for TXR pattern functions. Now there is. * eval.c (eval_init): Register match-fboundp intrinsic. * match.c (match_fbound): New function. * match.h (match_fbound): Declared. * tests/011/txr-case.txr: New test cases. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* keyparams: fix broken.Kaz Kylheku2022-01-171-34/+21
| | | | | | | | | | | | | | | | | | | Issues reported by user vapnik spaknik. The evaluation of init forms is incorrect. Init forms like '(x) evaluate to '(x) rather than (x), Also, init forms are evaluated even when the argument is present, so the entire current approach is wrong. * stdlib/keyparams.tl (extract-keys, extract-keys-p, build-key-list-expr): Functions removed. (stuff-key-params): New function. (:key): Rework using simplified approach, with just the stuff-key-params helper. All variables from the keyword parameter list are bound with let. Generated code searches the keyword parameters for values and assigns the variables as needed, evaluating default init forms in the not-found cases. * tests/011/keyparams.tl: New file.
* quips: a turn toward the slightly macabre.Kaz Kylheku2022-01-171-0/+1
| | | | * stdlib/quips.tl (%quips%): New entry.
* compiler: two optimizations, motivated by optional params.Kaz Kylheku2022-01-141-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The motivating situation is this: (lambda (: (opt :)) opt) When the default value of an optional parameter is : then the net effect is that there is no optional substituion. The optional argument is signaled by the : symbol, and that same symbol then replaces the value. This is not optimized well: data: 0: : 1: t syms: code: 0: 8C000009 close t2 0 3 9 1 0 nil t2 1: 00000002 2: 00000001 3: 00000003 4: 00000002 5: 3C000008 ifq t2 d0 8 6: 00020400 7: 2C020400 movsr t2 d0 8: 10000002 end t2 9: 10000002 end t2 instruction count: 5 entry point: 4 The instruction sequence 5: 3C000008 ifq t2 d0 8 6: 00020400 7: 2C020400 movsr t2 d0 8: serves no purpose; it's like: (if (eq x y) (set x y)) With this commit it looks like: data: 0: : 1: t syms: code: 0: 8C000006 close t2 0 3 6 1 0 nil t2 1: 00000002 2: 00000001 3: 00000003 4: 00000002 5: 10000002 end t2 6: 10000002 end t2 instruction count: 3 entry point: 4 * stdlib/optimize.tl (basic-blocks peephole-block): Here, we add an optimization for the useless assignment pattern. If an "ifq tx dy label" instruction falls through to a "mov tx dy", then we remove that move instruction from the next block. But only if that next block has nothing else jumping to it! If there are other jumps there, they could be relying on that "mov tx dy", so it cannot be removed. (basic-blocks elim-next-jump): The above optimization may leave us with a useless ifq instruction, which jumps to the same destination whether the comparison is true or not. In elim-next-jmp, we took care only of jmp instructions which uselessly jump to the next block in instruction order. We fix this to also eliminate if and ifq instructions whose destination label is the next block; they are equivalent to an unconditional jump.
* typecase: return nil from formless clauses.Paul A. Patience2022-01-121-1/+1
| | | | | * stdlib/type.tl (typecase): Return nil (as documented) instead of t when a matching clause has no clause forms.
* New macros: each-true, some-true, each-false, some-false.Kaz Kylheku2022-01-122-10/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisplib.c (arith_each_set_entries): Trigger autoload on new symbols. * stdilb/arith-each.tl (sys:arith-each): Generalize macro to handle short-circuiting logical operations. The op-iv parameter, which is a cons, is spread into two op and iv parameter. One new argument appears, short-circ. This specifies a code for short-circuiting behavior: t means iteration continues while the result is true; nil means it continues while it is nil, and + means iteration continues while the accumulator is nonzero. A new convention is in effect: the operator has to be specified as a list in order to request accumulating behavior, e.g (+) or (*). Otherwise the operator specifies a predicate that is applied to the forms, without taking into account the prior value. (sum-each, sum-each*, mul-each, mul-each*): Spread the op-iv arguments. Wrap the op argument in a list to request accumulation. In the case of mul-each and mul-each*, specify + for the short-circ argument, which means that iteration stops when the accumulator becomes zerop. sum-each and sum-each* specify : for the short-circ argument which is unrecognized, and so ther is no short-circuiting behavior. (each-true, some-true, each-false, some-false): New macros. * tests/016/arith.tl: New tests. * txr.1: Documented new macros and added note about possible short-circuiting in mul-each and mul-each*. * stdlib/doc-syms.tl: Updated.
* sum-each, mul-each: handle no vars case.Kaz Kylheku2022-01-111-9/+13
| | | | | | | | | | | | | | | * stdlib/arith-each.tl (sys:arith-each): If there are no vars, then just reduce to the identity element value. This is alreading happening fine for the each-prod family of operators. * tests/016/arith.tl: Test cases covering the no vars and empty iteration identity element cases for sum-each and mul-each, as well as the *-prod variants. * txr.1: Document empty iteration and empty vars behavior for arithmetic each operators as well as the each-prod family.

| | | | | * stdlib/match.tl (expand-quasi-match): Fix too few arguments to compile-error for format args.
* new feature: :mass-delegate struct clause macro.Kaz Kylheku2021-12-232-0/+28
| | | | | | | | | | | | | | | 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.
* new feature: defstruct clause macros.Kaz Kylheku2021-12-222-17/+56
| | | | | | | | | | | | | | | | | | | | | | * 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.
* defstruct: refactor with local function.Kaz Kylheku2021-12-221-147/+146
| | | | | | | | * stdlib/struct.tl (defstruct): Move the large tree-case in the loop which calculates the expanded slot syntax into a local function called expand-slot. This anticipates the addition of application-defined slot expanders, which will produce output that has to be recursed upon.

The new subst drop-in replaces this one. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* product/arithmetic each: missing block nil.Kaz Kylheku2021-12-202-32/+53
| | | | | | | | | | | | | | | | | | | * stdlib/arith-each.tl (sys:vars-check): New function, copy and pasted from each-prod.tl. (sys:arith-each): New macro. (sum-each, sum-each*, mul-each, mul-each*): Reworked using sys:arith-each macro. This macro uses logic borrowed from a stripped-down expand-each in the compiler. * stdlib/each-prod.tl (sys:expand-each-prod, sys:expand-arith-each-prod*): Add the block nil around the mapping call, taking care that the initialization forms are evaluated outside of the block, and their values bound to gensyms that then form the function arguments. * txr.1: Document the missing requirements for all the affected macros that there must be an anonymous block around the body, which, if used, determines the return value.
* tree: new functions for priority queue operation.Kaz Kylheku2021-12-181-0/+4
| | | | | | | | | | | | | | | | * tree.c (tree_min_node, tree_min, tree_del_min_node, tree_del_min): New functions. (tree_init): tree-min-node, tree-min, tree-del-min-node, tree-del-min: New intrinsics registered. * tree.h (tree_min_node, tree_min, tree_del_min_node, tree_del_min): Declared. * txr.1: Documented. * tests/010/tree.tl: New tests. * stdlib/doc-syms.tl: Updated.
* tree: support for duplicate keys.Kaz Kylheku2021-12-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tree.c (tr_insert): New argument for allowing duplicate. If it is true, suppresses the case of replacing a node, causing the logic to fall through to traversing right, so the duplicate key effectively looks like it is greater than the existing duplicates, and gets inserted as the rightmost duplicate. (tr_do_delete_specific, tr_delete_specific): New static functions. (tree_insert_node): New parameter, passed to tr_insert. (tree_insert): New parameter, passed to tree_insert_node. (tree_delete_specific_node): New function. (tree): New parameter to allow duplicate keys in the elements sequence. (tree_construct): Pass t to tree to allow duplicate elements. (tree_init): Update registrations of tree, tree-insert and tree-insert-node. Register tree-delete-specific-node function. * tree.h (tree, tree_insert_node, tree_insert): Declarations updated. (tree_delete_specific_node): Declared. * lib.c (seq): Pass t argument to tree_insert, allowing duplicates. * parser.c (circ_backpatch): Likewise. * parser.y (tree): Pass t to new argument of tree, so duplicates are preserved in the element list of the #T literal. * y.tab.c.shipped: Updated. * tests/010/tree.tl: Test cases for duplicate keys. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: fix broken (compile '(lambda ...)).Kaz Kylheku2021-12-141-15/+17
| | | | | | | | | | * stdlib/compiler.tl (compile): The symbol-function function returns true for lambda and that's where we are handling lambda expressions. However, the (set (symbol-function ...) ...) then fails: that requires a function name that designates a mutable function location. Let's restructure the code with match-case, and handle the lambda pattern separately via compile-toplevel.
* compiler: small end/jend issue in late-peephole.Kaz Kylheku2021-12-111-1/+1
| | | | | | | | | * stdlib/optimize.tl (basic-blocks late-peephole): In one pattern, an instruction that is recognized as (jend ...) is inadvertently rewritten to (end ...).
