* doc: document catenated .tlo files.Kaz Kylheku2022-02-131-0/+35
| | | | | * txr.1: Under load and compile-file, mention the support for loading catenated .tlo files.
* New function: cat-files.Kaz Kylheku2022-02-134-1/+35
| | | | | | | | | | | * 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.
* load: support loading catenated .tlo files.Kaz Kylheku2022-02-131-13/+20
| | | | | | | | * parser.c (read_file_common): Tolerate the presence of version expressions, as long as they match the initial version under equal. Thus a larger .tlo file can be made of two or more .tlo files by simple catenation; it will load as long as they have exactly the same version.
* all: wrong self name.Kaz Kylheku2022-02-131-1/+1
| | | | * lib.c (all_satisfy): self should be "all" rather than "some".

| | | | | | | * 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.
* doc: add missing < and << in some .mets lines.Paul A. Patience2022-02-121-13/+13
| | | | | * txr.1: Add < and << in the signatures of various stream methods.
* WIP getopts: allow specifying arg names in help.Paul A. Patience2022-02-121-6/+27

| | | | | | | | * 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. Patience2022-02-122-7/+17
| | | | | | | * 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.

| | | | | | | | | | | | | * 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: test case for `@{nil #/regex/}`.Kaz Kylheku2022-02-091-0/+2
| | | | * tests/011/patmatch.tl: New tests for recently fixed issue.
* doc: fix references to inexistent handler macro.Paul A. Patience2022-02-091-4/+4
| | | | * txr.1: Correct "handler" to "handle".
* 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.
* doc: fix issues in arguments to .I macros.Paul A. Patience2022-02-091-11/+11
| | | | | | | * txr.1: Correct .I to .IR when the arguments include trailing punctuation. Add quotes around multiword .I and .IR arguments to be consistent everywhere. Unitalicize "de facto". Fix accidental trailing sentence.

| | | | * txr.1: Document pad's object parameter as optional.
* 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. Patience2022-02-082-7/+7
| | | | | | | | | | | | | | | | 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 a few more typos.Paul A. Patience2022-02-071-10/+11
| | | | * txr.1: Fix typos.
* lib: fix return value of separate for nil seq.Paul A. Patience2022-02-071-1/+1
| | | | | * lib.c (separate): Return (list nil nil) instead of just nil when the sequence parameter is nil, as is documented.
* txr: -D bugfixes.Kaz Kylheku2022-02-061-12/+25
| | | | | | | * txr.c (txr_main): Don't use split_str to break -Dvar=val syntax, because that splits on all occurrences of the = character. Secondly, diagnose -Da,b,c shape: list commas occur with no = sign.
* doc: fix various typos and stylistic issues.Paul A. Patience2022-02-062-79/+87
| | | | | | * txr.1: Fix typos and stylistic issues. * stdlib/doc-syms.tl: Updated.
* Use null_string throughout code base.Kaz Kylheku2022-02-056-11/+12
| | | | | | | | | | | | | | | | * eval.c (load): Use null_string instead of lit(""). * lib.c (obj_init): Likewise. * match.c (LOG_MATCH, LOG_MISMATCH, do_txeval): Likewise. * parser.c (regex_parse, lisp_parse_impl, find_matching_syms): Likewise. * stream.c (do_parse_mode): Likewise. * txr.c (sysroot_init): Likewise. (txr_main): Replace string(L"") with null_string.
* doc: no such thing as -Da,b,cKaz Kylheku2022-02-051-2/+4
| | | | | * txr.1: Fix the example -Da,b,c to -Dvar=a,b,c. Reported by Paul A. Patience.
* txr: bind -D-valueless variables to empty string.Paul A. Patience2022-02-051-1/+1
| | | | | * txr.c (txr_main): Bind variables specified with -D but without values to the empty string, as documented in the manual.
* vim: improvement multi-line strings.Kaz Kylheku2022-02-041-5/+5
| | | | | | | | | | | | | | | | | | Vim's handling of multi-line Lisp strings is glitchy. We are contributing to it by tryign to match the backslash-newline as an escape sequence. As a result of this change, Vim is less confused. Indentation is still incorrect after some multi-line strings, but I'm not seeing the discrepancy between the behavior of the visual parentheses matching, and the % parentheses jump. I'm able to navigate around in the stdlib/getopts.tl code. * genvim.txr (chesc): Remove the backslash-newline from the list of character escapes. (txr_string, txr_quasilit, txr_regex, tx_regex): Use skip= to recognize the backslash-newline sequence as part of the literal.
* 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 Kylheku2022-02-042-4/+8
| | | | | | | | * 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 Kylheku2022-02-034-92/+143
| | | | | | | | | | | | | | | | * 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 Bloggs2022-02-032-74/+79
| | | | | | | | | | * 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.
* doc: fix in amb macro.Kaz Kylheku2022-02-031-2/+3
| | | | | | | | | | | | | | * txr.1: when the amb macro detects that the continuation has succeeded, it should return that successful value from the amb-scope, rather than returning the local successful argument a from the amb function. Although it works both ways, it is inefficient when it returns from the function. The reason is that each call to amb executes the successful future twice: once via (call cont a) and then again by returning the a value. This then causes an exponential cascade in calls: each successive amb call sthe successful future twice, so for instance if the solution has a sequence of 8 amb calls, the successful case is reached 256 times.
* quip: joke about dark mode.Kaz Kylheku2022-02-031-0/+1
| | | | * quips.tl (%quips%): New one.
* doc: window-mappend typo.Kaz Kylheku2022-02-021-1/+1
| | | | | * txr.1: The window-mapdo function is analogous to mapdo, not window-mappend. Reported by vapnik spaknik.
* 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 Kylheku2022-01-303-36/+39
| | | | | | | * 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.
* mpi: compile out more unused functions.Kaz Kylheku2022-01-281-0/+6
| | | | | * mpi.c (mp_mul_2, mp_2expt, mp_addmod, mp_submod, mp_mulmod, mp_sqrmod): Excluded from compilation.
* random-sample: replace algorithm R.Kaz Kylheku2022-01-291-4/+13
| | | | | | | | | * rand.c (random_sample): The brnach of the code for lists is converted from the naive algorithm R which requires a random integer for each element of the sequence to a list adaptation of the smarter algorithm L used for vector. We don't have random access through the list being sampled, but we can step to new positions without generating random numbers.
* New function: random-sample.Kaz Kylheku2022-01-293-4/+97
| | | | | | | | | | | | | | | | 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.
* listener: line_w must be volatile now.Kaz Kylheku2022-01-281-1/+1
| | | | | | | | | * parser.c (repl): The line_w variable must be volatile because it's modified after we save the context for catching exceptions. Without this, I'm seeing that expressions that throw an exception are not being entered into the linenoise history, because the exception catch restores the null initial value of line_w.
* listener: handle Ctrl-C interrupts from linenoise.Kaz Kylheku2022-01-281-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an issue that affects plain mode, because in full editing mode, linenoise reads Ctrl-C as a character. In plain mode, Ctrl-C-generated SIGINT behaves curiously. The ^C characters appear, and the current line of input is discarded. This is because the linenoise() call is not enclosed in the catch region. The registered signa handler goes off, and repl_intr is called. Thta function throws the intr exception. Since that exception isn't derived from error, and there is no handler for it, nothing happens. The signal handler just returns. In this fix, we move the linenoise call into the catch region of the REPL loop, so the interrupt is handled. The entire multi-line input is aborted, an ** intr message is printed, and the REPL waits for another line. Issues reportd by Paul A. Patience. * parser.c (repl): Move the uw_catch_begin above the linenoise call. This means that the surrounding code can no longer use continue to continue the loop, or break to terminate. Instead of "continue" we go to a new "contin" label placed at the bottom of the catch processing, just before the end of the loop. The EOF case now sets the done fag and also branches to that label. Some free(line_w) calls no longer have to be done because the unwinding block takes care of it. In the exception catching block, we no actually check for the intr_s exception.
* linenoise: issue newline on EOF in plain mode.Kaz Kylheku2022-01-281-0/+2
| | | | | | | * linenoise/linenoise.c (linenoise): In plain mode, like in full editing mode, when EOF is detected, print a newline so that when TXR exit to an interactive shell, the shell's prompt starts on a new line.
* linenoise: Ctrl-V Ctrl-J now inserts CR not LF.Kaz Kylheku2022-01-281-0/+4
| | | | | | | | | | | | | | If newlines are inserted into the input, they don't behave well. The is_balanced_line callback doesn't recognize them as line terminators for the purposes of delimiting ; comments. Also, they make a mess in the ~/.txr_history file. Plus, users of shells like Bash are used to Ctrl-V Ctrl-J inserting a line break; some users have that in their muscle memory. So let's just do that as a special case: Ctrl-V Ctrl-J behaves like Ctrl-V Ctrl-M. * linenoise/linenoise.c (history_search, edit): Remap a verbatim Ctrl-J to a carriage return.
* repl: bug handling comments in plain mode.Kaz Kylheku2022-01-281-6/+4
| | | | | | | | | | | | | | | | | | | The is_balanced_line function assumes that comments are terminated by a carriage return, whic his the multi-line convention used by the interactive repl. The plain-mode listener, though, only replaces newlines by carriage returns when returning the complete multi-line input. When invoking the is_balanced_line callback, the newlines are still there, and so comments are not handled properly. Reported by Paul. A. Patience. * linenoise/linenoise.c (linenoise): In plain mode, replace the trailing newline with a carriage return after every physical line input, before that line is passed to the lino->enter_callback (i.e. is_balanced_line). The code to replace newlines with carriage returns at the end is consequently no longer required.
* New function: copy-cptr.Kaz Kylheku2022-01-286-1/+35
| | | | | | | | | | | | | | | * 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.
* filter: actually throw from filter-string-tree.Paul A. Patience2022-01-271-2/+4
| | | | | | | | | * filter.c (filter_string_tree): The function tries to call uw_throwf when an invalid filter is provided, but an overzealous return statement renders the effort futile. Remove the return statement, change the exception type from error_s to type_error_s, and conform the message to the usual type-error style.
