* place: fix bad indentation.Kaz Kylheku2025-03-111-4/+4
| | | | | | * stdlib/place.tl (sys:placelet-1): Fix a misindented call-update-expander function call. Also indent its arguments in function style.
* Expose brace expansion bexp function.Kaz Kylheku2025-03-094-175/+229
| | | | | | | | | | | | | | | | | * autoload.c (glob_set_entries): Remove autoload on sys:brace-expand. Add usr:exp. * stdlib/glob.tl (brace-expand): Renamed to usr:bexp. (glob*): Call bexp rather than brace-expand. * tests/018/glob.tl: Rename references to sys:brace expand to bexp. * txr.1: Add section describing the bexp function. Move brace expansion documentation from glob* to this new section, adjusting the wording a little bit, mainly to avoid referring to "patterns". Point glob* documentation to bexp, which also in turn references glob*.
* glob*: add string and integer ranges to brace expansion.Kaz Kylheku2025-03-083-19/+229
| | | | | | | | | | | | | | | | * stdlb/glob.tl (bexp-parse): Recognize .. as a token. (bexp-parse-brace): If a brace expansion doesn't contain commas, then check whether it contains .. and that its elements are all strings. In that case it is a possible range expansion and we thus transform it to a (- ...) node, subject to more validation in bexp-expand. (bexp-expand): Add casees to handle range expansion, taking care that invalid forms translate to verbatim syntax. * tests/018/glob.tl: New tests. * txr.1: Documented.
* repl: fix abort: tab completion over nonexistent package.Kaz Kylheku2025-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a problem caused by b7a7370a921bbc02b54d87600ff74d5cb9efde28, on Feb 4, 2020, which adds unwinding logic into the provide_completions function. Two return statements are correctly turned into "goto out", but one is overlooked. When this stray return statement is executed, it leaves dangling unwind frames in the unwind stack, causing an assertion when control returns to the repl function which calls uw_pop_frame to remove an unwind frame that it pushed. Steps to reproduce: 1. complete a symbol with a nonexistent package 1> (foo:bar[Tab] 2. Backspace over it (or use Ctrl-U) and hit Enter: 1> txr: unwind.c:296: uw_pop_frame: Assertion `fr == uw_stack' failed. Aborted (core dumped) * parser.c (provide_completions): When find_package fails, return by executing goto out, rather than return, so that the catch frame is removed.
* New feature: range iteration with skip.Kaz Kylheku2025-03-074-8/+122
| | | | | | | | | | | | | | | | | | | | | | | | | | The notation X..Y..Z now denotes an iterable range, if X..Y is a valid iterable range on its own, and Z is a positive integer. Z gives a step size: 1 takes every element, 2 every other and so on. * lib.c (seq_iter_get_skip, set_iter_peek_skip): New static functions. (si_skip_ops): New static structure. (iter_dynamic): Function relocated earlier in file to avoid forward declaration. (seq_iter_init_with_info): When the iterated object is a range, check for the to element itself being a range. If so, it is potentially a skip iteration. Validate it and implement via a skip iterator referencing a dynamic range iterator. * lib.h (struct seq_iter): New sub-union member, ul.skip. We could use an existing member of type cnum; this is for naming clarity. * tests/012/iter.tl: New tests. * txr.1: Documented.
* New function: iterp.Kaz Kylheku2025-03-075-31/+139
| | | | | | | | | | | | | | | | | * eval.c (eval_init): Register iterp intrinsic. * lib.[ch] (iterp): New function. * tests/012/iter.tl: New tests. * txr.1: Document iterp. Update documentation for iter-more, iter-item and iter-step to more precisely identify which objects are valid arguments in terms of iterp and additional conditions, and that other objects throw a type-error exception. Fix wrong references to iter-more under documentation for iter-item. Removed obsolete text specifying that iter-step uses car on list-like sequences, a dubious behavior removed in the previous commit.
* iterator API: reject objects that don't make sense.Kaz Kylheku2025-03-062-14/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (iter_more): Do not return t for unrecognized objects, but thrown an exception. Do return t for conses, which is necessary since they are iterators for lists. Also, as a special case, we return t for struct objects that don't have an iter-more method. This is needed for the documented fast protocol. Iterator objects implementing the fast protocol still get iter-more invoked on them. The client usually doesn't know that the iterator implements the fast protocol, and so calls iter-more, which unconditionally has to returns true. (iter_item): Do not fall back on car(iter) for all unhandled objects. Only conses are handled via car. All unrecognized objects trigger an exception. (iter_step): Do not try to handle list-like objects via cdr, only lists. Improve the diagnostic for hitting the end of an improper list: diagnostic shows the cons cell rather than just the terminating atom. * tests/012/iter.tl: Some test cases validating that the functions error out for strings and vectors. Much more coverage is possible here but doesn't seem worth it; e.g. that the functions reject a buffer, regex, function, ...
* build: don't create .build_id file for non-users of build_id.Kaz Kylheku2025-02-251-0/+4
| | | | | | | | | | * Makefile: put the current build_id into the .build_id file only if it is nonblank. If it is blank, then delete the file if it exists. This handles the case when the build_id user removes the build_id. A rebuild of txr.o is forced one last time, and the .build_id is removed. Users who don't know about build_id or don't use it will no longer see a blank .build_id file being created.
* configure: fix bad gcc verison check.Kaz Kylheku2025-02-181-9/+24
| | | | | | | | | | | | | | | * configure: The way the verison is represented in the output of gcc varies. A vendor build version may be indicated in parentheses, and that may precede or follow the version number by itself. I don't know all the variations. What I'm implementing here is looping over the white-space separated output of gcc --version, looking for an item of the form number.number.number where number is any decimal string from 0 to 99 with no leading zero, except for zero itself. If we find this item, we assume that is the gcc version, and break it up and process it as before, terminating the loop. We print the parsed gcc version in parentheses to help with spotting problems.
* Version 299.txr-299Kaz Kylheku2025-02-166-1198/+1257
| | | | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date. * txr.vim, tl.vim: Regenerated.
* ffi: rework endian-type rput/rget routines on big endian.Kaz Kylheku2025-02-151-24/+40
| | | | | | | | | | | | | * ffi.c (ffi_be_i16_rput, ffi_be_i16_rget, ffi_be_u16_rput, ffi_be_u16_rget, ffi_be_i32_rput, ffi_be_i32_rget, ffi_be_u32_rput, ffi_be_u32_rget, ffi_le_i16_rput, ffi_le_i16_rget, ffi_le_u16_rput, ffi_le_u16_rget, ffi_le_i32_rput, ffi_le_i32_rget, ffi_le_u32_rput, ffi_le_u32_rget): Rewriten to avoid memory clearing, memsets, pointer arithmetic and use of helper functions. The big endian rput and rget functions just wrap the non-endian versions. The ones which need byte swapping work in terms of a full ffi_arg word. For instance to prepare a 16 bit big endian unsigned return value we byte swap the uin16_t, then convert fo ffi_arg.
* ffi: big endian: broken be-int16 closure return.Kaz Kylheku2025-02-131-1/+1
| | | | | | | * ffi.c (ffi_be_i16_rput): We need to memset the remaining parts of the 64 bit word to 0, like in all the other ffi_be_xxx_put functions that are less than 64 bits wide. Also removing the (void) tft cast is removed since tft is used.
* ffi: big endian: broken int8 and uint8 return values.Kaz Kylheku2025-02-131-4/+6
| | | | | | | | | | | | * ffi.c (ffi_i8_rput, ffi_i8_rget, ffi_u8_rput, ffi_u8_rget): These functions are not doing the correct job; they are just casting the pointer to the target type, like on little endian. The big endian rget must fetch the entire 64 bit word (ffi_arg) and convert its value to the target type. If it's a character value, the actual bits are found at *(src + 7) not at *src. The rput function must do the reverse; convert the value to the 64 bit ffi_arg and store that.
* vm: missed cases of signal check in backwards branchKaz Kylheku2025-02-071-6/+15
| | | | | | | | | | | | Only the JMP instruction is checking for a backwards branch and calling sig_check_fast() so that a loop can be interrupted by Ctrl-C. The compiler can optimize that so that a backwards jump is performed by an instruction in the IF family. * vm.c (vm_if, vm_ifq, vm_ifql): Check for a backwards branch and call sig_check_fast. Also, eliminate the redundant call to vm_insn_bigop, which is just a masking macro. The ip variable is already the result of vm_insn_bigop.
* read-until-match: streamline get_char calls.Kaz Kylheku2025-01-301-3/+7
| | | | | | | | | | | | | Similarly to what was done in get_csv, we optimize he use of get_char and unget_char. I see a 7.5% speed improvement in a simple benchmark of the awk macro with the record separator rs set to #/\n/. * regex.c (scan_until_common): Obtain the strm_ops operations of the stream, and pull the low level get_char and unget_char virtual operations from it. Call these directly in the loop. Thereby, we avoid all the type checking overhead in these functions.
* get-csv: further get-char optimization.Kaz Kylheku2025-01-301-15/+6
| | | | | | | | | | | Another 5-6% gained form this. * stream.c (us_get_char, us_unget_char): Static functions removed. (get_csv): Retrieve the get_char and unget_char pointers from the strm_ops structure outside of the loop, and then just call these pointers. Careful: the unget_char virtual has reversed parameters compared to the global function.
* get-csv: use unsafe version string-extend.Kaz Kylheku2025-01-303-11/+49
| | | | | | | | | | | | | | | Another almost 16% speedup. * lib.c (us_length_STR): New static function. (string_extend): Use us_length_STR, since we know the object is of type STR. (us_string_extend_STR_CHR): New function. (length_str): Handle STR case via use_length_STR. * lib.h (us_string_extend_STR_CHR): Declared. * stream.c (get_csv): Use us_string_extend_STR_CHR instead of string_extend.
* string-extend: don't use set macro to update length.Kaz Kylheku2025-01-301-1/+1
| | | | | | | * lib.c (string_extend): We know that num_fast + delta is in the fixnum range, because we checked this condition. So we can just assign it without informing the garbage collector. This yields about a 16% speedup in get-csv.
* awk: add CSV support.Kaz Kylheku2025-01-303-3/+82
| | | | | | | | | | | * stdlib/awk (awk-state upd-rec-to-f): Handle a new case of fs being the keyword symbol :csv, producing a field-splitting lambda that calls get-csv. * tests/015/awk-basic.tl: Several new test cases for this CSV feature. * txr.1: Documented.
* get-csv: speed up with unsafe get-char.Kaz Kylheku2025-01-301-4/+17
| | | | | | | | | I'm seeing about a 6% improvement in get-csv from this. * stream.c (us_get_char, us_unget_char): New static functions, which assume all arguments have correct type. (get_csv): If we use source_opt, validate that it's a stream with class_check. Use us_get_char and use_unget_char.
* cobj: optimize subclass checks based on depth 1 assumptionKaz Kylheku2025-01-301-10/+6
| | | | | | | | | | | | | | | | | Nowhere in the image do we have cobj_class inheritance deeper than one. No class has a superclass which itself has a superclass. Based on this, we can eliminate loops coded to handle the general case. * lib.c (sutypep, cobjclassp): Do not iterate to chase the chain of super pointers. Do the subclass check based on the assumption that there is at most a super pointer to class which itself then has no super. (cobj_register_super): Assert if the situation occurs that a class is registered with a super that is not a root. All these calls take place on startup, so if the assumption is wrong, the assert will be 100% reproducible.
* vector: ensure minimum alloc size.Kaz Kylheku2025-01-291-6/+7
| | | | | | | | | | | | | | Like in a recent commit for mkstring, we impose a minimum allocation size of 6 for vectors, which means 8 cells together with the two informaton words at the base of the vector. * lib.c (vec_own): Take an alloc parameter in addition to the length, which is stored in v[vec_alloc]. (vector): Impose a minimum alloc size of 6. (copy_vec, nested_vec_of_v): Pass alloc parameter to vec_own which is the same as the length parameter; i.e. no behavior change for these functions.
* string-extend: grow faster.Kaz Kylheku2025-01-291-2/+2
| | | | | | | * lib.c (string_extend): When more space is needed in the string, grow by 50% rather than 25%. This speeds up code at the expense of some wasted space. Waste space can be dealt with by the final flag in programs where it matters.
* mkstring: minimum 7 char alloc size.Kaz Kylheku2025-01-291-2/+3
| | | | | | * lib.c (mkstring): Do not allocate less than 8 characters, including null terminator, to the string. This speeds up code which builds up strings from empty, one character at a time.
* build: remove HAVE_MALLOC_USABLE_SIZE.Kaz Kylheku2025-01-293-66/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The malloc_usable_size use in the STR type actually makes operations like string_extend substantially slower. It is faster to store the allocated size locally. Originally, on platforms that have malloc_usable_size, we were able to use the word of memory reclaimed from the string type to store a cached hash code. But that logic was revereted in 2022, so there is no such benefit. * configure (have_malloc_usable_size): Variable removed. Test for the malloc_usable_size function removed. (HAVE_MALLOC_USABLE_SIZE, HAVE_MALLOC_NP): Do not define these preprocessor symbols. * lib.c (HAVE_MALLOC_NP_H): Do not test for this variale to include <malloc_np.h> (string-own, string, string_utf8, mkstring, mkustring, string_extend, string_finish, string_set_code, string_get_code, length_str): Eliminate #ifdefs on HAVE_MALLOC_USABLE_SIZE. * lib.h (struct wstring): Eliminate #ifdef on MALLOC_USABLE_SIZE, so alloc member is unconditionally defined on all platforms.
* awk: use prepared lambdas for field separation.Kaz Kylheku2025-01-283-64/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle field separations with lambdas, similarly to record separation. The idea is that we replace the rec-to-f method, which contains a cond statement checking the variables for which field separation discipline applies, with a lambda which is updated whenever any of those ariables change. * awk.tl (awk-state): New instance slot, rec-to-f. (awk-state :postinit): Call new upd-rec-to-f method so that rec-to-f is populated with the default field separating lambda. (awk-state rec-to-f): Method removed. (awk-state upd-rec-to-f): New method, based on rec-to-f. This doesn't perform the field separation, but returns a lambda which will perform it. (awk-state loop): We must call upd-rec-to-f whenever we change par-mode, because it influences field separation. (awk-mac-let): Replace the symbol macros fs, ft, fw and kfs with new implementations that use the reactive slot mechanism provided by rslot. Whenever the awk macro assigns any of these, the upd-rec-to-f method will be called. * tests/015/awk-basic.tl: New file. These basic tests of field separation pass before and after this change. * tests/common.tl (otest, motest): New macros.
* doc: *print-flo-format*: show string value in quotes.Kaz Kylheku2025-01-251-1/+1
| | | | | * txr.1: The example possible value "~3,4f" should be shown as a string literal in quotes.
* get-csv: bugfix: return nil on EOF.Kaz Kylheku2025-01-243-5/+40
| | | | | | | | | | | | | | | | | * stream.c (get_csv): Let's add a new state init. If get_char returns nil and we are in the init state, let's bail to a nil return. While we are at it, let's not allocate the record or string until we read at least one character. If we read a character in the init state, let's allocate those two objects, and then change to the rfield state and fall through to it to handle the character. * tests/010/csv.tl: Fix one incorrect test: (tocsv "") now returns nil, as it should. Add tests for multiple record extraction, also covering missing line termination on the last record as well as CR-LF termination. * txr.1: Documented nil return conditions.
* New functions for producing CSV.Kaz Kylheku2025-01-244-0/+111
| | | | | | | | | | | | * stream.c (put_csv, tocsv): New functions. (stream_init): put-csv and tocsv intrinsics registered. * stream.h (put_csv, tocsv): Declared. * tests/010/csv.tl (mtest-pcsv): New macro. New test cases. * txr.1: Documented.
* doc: split Data Interchange Support section.Kaz Kylheku2025-01-241-1/+3
| | | | * txr.1: Split Data Interchange Support into JSON and CSV.
* get-csv: refactor into switches.Kaz Kylheku2025-01-211-19/+26
| | | | | | | * stream.c (get_csv): All cases handle end-of-stream the same way, so we check for nil outside of the case switch. Then only characters need to be handled, so we can call c_chr(ch) and switch on it.
* get-csv: rewrite in C.Kaz Kylheku2025-01-214-91/+79
| | | | | | | | | | | | | | * autload.c (csv_set_entries, csv_instantiate): Functions removed. (autoload_init): Autoload registration for stdlib/csv removed. * stdlib/csv.tl: File removed. * stream.c (get_csv): New function. (stream_init): Register get-csv intrinsic. * stream.h (get_csv): Declared.
* get-csv: use symbols for states.Kaz Kylheku2025-01-211-45/+44
| | | | | | * csv.tl (get-csv): Since there are only three states, there is no jump table optimization. We might as well use keyword symbols for the states rather than integers.
* get-csv: simplify implementation by CR-LF folding.Kaz Kylheku2025-01-211-30/+7
| | | | | | | | | * stdlib/csv.tl (get-csv): Pre-process the input by a small state machine that maps CR-LF sequences to LF. Then we don't have to recognize #\return anywhere in the state machine and can delete the cr and qcr states, as well as all the code recognizing #\return and branching to those states.
* New function: get-csv.Kaz Kylheku2025-01-214-0/+373
| | | | | | | | | | | | | * autloload.c (csv_set_entries, csv_instantiate): New static funtions. (autoload_init): Register autoload of stdlib/csv module via new functions. * stdlib/csv.tl: New file. * tests/010/csv.tl: Likewise. * txr.1: Documented.
* New macros for enumerated constants.Kaz Kylheku2025-01-204-0/+174
| | | | | | | | | | | | | * autoload.c (enum_set_entries, enum_instantiate): New static functions. (autoload_init): Register autoload of stdlib/enum module via new functions. * stdlib/enum.tl: New file. * tests/016/enum.tl: Likewise. * txr.1: Documented.
* Makefile: tidy up clean targets.Kaz Kylheku2025-01-171-3/+12
| | | | | | | | | | | | | * Makefile (clean): Do not remove the run.sh file here. That is a temporary file that install-tests should be cleaning away when done, which we can remove in distclean. (clean-doc, clean-tests): New targets, which let us clean up generated documentation files and the test-generated state information in tst. (distclean): Do not remove the documentation stuff here; rely on clean-doc. Also depend on clean-tests. Do remove run.sh here. (install-tests): Add missing .PHONY. Remove run.sh.
* lflow/lopip: optimize one argument situations via lop1.Kaz Kylheku2025-01-171-21/+25
| | | | | | | | | | | | | | | | | | | | | | | In an opip pipeline, only the first pipeline element can receive multiple arguments. The subsequent elements receive the single return value from the previous element. Therefore if it is a left-inserting pipeline created by lopip, only the first element needs to use lop. The others can use lop1, resulting in an optimization. Furthermore in the flow/lflow macros, even the first function in the pipeline is called with one argument: the result of the input expression. So the case of lflow, every element of the pipe that would translate to lop can go to lop1 instead. * stdlib/opt.tl (sys:opip-expand): Calculate a local variable called opsym-rest which determines which op symbol we use for the recursive call. This is the same as the incoming opsym, except in the case when opsym is lop, in which case we substitute lop1. (sys:lopip1): New macro, like lopip but uses lop1 for the first element also. (lflow): Expand to sys:lopip1 rather than lopip.
* New macro: lop1.Kaz Kylheku2025-01-174-3/+66
| | | | | | | | | | | | | * autoload.c (op_set_entries): Autoload on lop1 symbol. * stldlib/op.tl (sys:op-expand): Add lop1 case. (sys:opip-expand): Add lop1 to the list of operators that are recgonized and specially treated. (lop1): New macro. * tests/012/op.tl: New tests. * txr.1: Documented.
* json: flat must override all effects of :standardKaz Kylheku2025-01-163-14/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | * stream.h (struct json_opts): Member flat removed. I noticed that !jo.flat was always being tested together with jo.fmt == json_fmt_standard. Except for a few places where the code only tested for json_fmt_standard, resulting in flat output, but some extra spaces. What distiguishes flat mode now is simply that we disable stream indentation. * lib.c (out_json_rec): Remove tests for !jo.flat. (out_json): Remove initialization of jo.flat member. In this function we set up indentation on the stream resulting in multi-line mode (existing behavior). (put_json): Remove initialization of jo.flat member. If flat mode is requested, then it overrides the format to json_fmt_default. I.e. json_fmt_standard coresponding to :standard is only in effect if flat is not requested. In this function we set up indentation on the stream if flat mode isn't requested, otherwise we disable indentation (existing behavior, enough to make flat work). * tests/010/json.tl: Tests for flat mode, :standard formatting, and combinaton of both.
* put_json: bug: incorrect defaulting of flat argument.Kaz Kylheku2025-01-151-2/+3
| | | | | | | | | | this also affects put_jsonl and tojson. * lib.c (put_json): The flat argument must be properly defaulted. Without this we are treating it as true when it is missing due to the convention that missing args are signaled by the : symbol. This bugs breaks the ability to use the :standard value for *print-json-format*.
* lop: don't insert args when metas present.Kaz Kylheku2025-01-083-26/+114
| | | | | | | | | | | | | | | | | | | | | The lop macro is inconsistent from op in that it inserts the trailing function arguments on the left even if arguments are explicitly given in the form via @1, @2, ... or @rest. This change makes lop is equivalent to op in all situations when these metas are given. * stdlib/op.tl (compat-225, compat-298): New top-level variables. (op-expand): local variable compat replaced by references to compat-225. If compat-298 is *not* in effect, then metas are checked for first in the cond, preventing the lop transformation from taking place. * tests/012/op.tl: Test cases for lop, combinations of do with lop and a few for op also. * txr.1: Redocumented, added compat notes.

* match-case: bugfix in conversion to casequal.Kaz Kylheku2024-12-202-2/+3
| | | | | | | | | | | | | * stdlib/match.tl (match-case-to-casequal): the (do inc dfl-cnt) action has a problem: it inserts an implicit extra parameter to the invocation of inc, which crashes the + addition due to that parameter being the matching @nil object. We don't need this entire case because it handles @nil, which also matches the following case for (sys:var ...), since @nil is (sys:var nil). That case ahs the same action of incrementing dfl-cnt. * tests/011/patmatch.tl: Test case added.
* Version 298.txr-298Kaz Kylheku2024-12-174-5/+17
| | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date.
* listener: regression: txr bails when .txr-profile missing.Kaz Kylheku2024-12-161-0/+3
| | | | | * parser.c (load_rcfile): When neither ~/.txr-profile nor ~/.txr_profile exist, then bail. Do not pass nil to abs-path-p and other functions.
* Version 297.txr-297Kaz Kylheku2024-12-166-735/+771
| | | | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date. * txr.vim, tl.vim: Regenerated.
* bug: string range length signed/unsigned.Kaz Kylheku2024-12-161-1/+2
| | | | | | | | * lib.c (length_str_range): On platforms where wchar_t is unsigned, we calculate bogus values for reversed ranges. On Android, gcc warns about the code, and the recently added tests fail. Let's cast the characters to long before doing the subtraction, which is the argument type of labs.
* string ranges: bug: ranges of length 1.Kaz Kylheku2024-12-153-2/+24
| | | | | | | | | * lib.c (seq_iter_init_with_info): String ranges are inclusive. We must not assume at a range whose endpoints are the same is empty; we must check that case for the endpoints being strings. * tests/012/seq.tl: New tests.
* tests for string range length.Kaz Kylheku2024-12-151-0/+12
| | | | * tests/012/seq.tl: New tests.
