* opip: pass through forms in the op family.Kaz Kylheku2022-02-241-1/+1
| | | | | | | | | | | | | | * 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 Kylheku2022-02-232-4/+12

* lisplib: split lisplib_try_load into namespaces.Kaz Kylheku2022-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisplib.c (lisplib_init): Change sys:try-load (only used by place.tl) to sys:try-load-fun, and register it to (lisplib_try_load): External function becomes static.

(lookup_fun, lookup_mac, rt_defun, rt_defmacro, fmakunbound, mmakunbound): Use lisplib_try_load_fun. (expand_param_macro): Use lisplib_try_load_keyword, which is a catch-all namespace for anything tied to keywords. * struct.c (make_struct_type, find_struct_type): Use lisplib_try_load_struct. (lookup_sloat_load, lookup_static_slot_load, lookup_static_slot_desc_load, slot_types, static_slot_types): Use lisplib_try_load_slot. * stdlib/place.tl (get-place-macro): Use try-load-fun, rather than try-load.
* New function: cat-files.Kaz Kylheku2022-02-132-0/+14
| | | | | | | | | | | * lisplib.c (copy_file_instantiate): Trigger autoload on cat-files. * stdlib/copy-file.tl (cat-files): New function. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* doc: remove extraneous symbols from doc-syms.Paul A. Patience2022-02-121-17/+0
| | | | | | | * genman.txr: Remove from the name list those names that are not TXR symbols, so that they don't appear in doc-syms. * stdlib/doc-syms.tl: Updated.
* WIP getopts: allow specifying arg names in help.Paul A. Patience2022-02-121-6/+27
| | | | | | | | * stdlib/getopts.tl (basic-type-p): Handle the cons case. (sys:opt-parsed convert-type): Same. (opthelp): Same. (opthelp-types): Same, and for each type in the legend, specify which arguments correspond to it.
* getopts: print legend entries in canonical order.Paul A. Patience2022-02-121-25/+26
| | | | | | | | * stdlib/getopts.tl (opthelp-types): Print the entries in a canonical order rather than in the order of the types' appearance in opt-desc-list. Also, remove one (superfluous) space before the hyphen in all entries and fix typos in the description of HEX and STR.
* getopts: include list/cumul subtypes in legend.Paul A. Patience2022-02-121-1/+6
| | | | | * stdlib/getopts.tl (opthelp-types): Consider list and cumul types when searching for types to include in the legend.
* 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.
