* Version 299.HEADtxr-299masterKaz Kylheku2025-02-161-1/+1
| | | | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date. * txr.vim, tl.vim: Regenerated.
* awk: add CSV support.Kaz Kylheku2025-01-301-0/+8
| | | | | | | | | | | * 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.
* awk: use prepared lambdas for field separation.Kaz Kylheku2025-01-281-64/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* get-csv: rewrite in C.Kaz Kylheku2025-01-211-74/+0
| | | | | | | | | | | | | | * 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 Kylheku2025-01-211-0/+98
| | | | | | | | | | | | | * 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 Kylheku2025-01-201-0/+46
| | | | | | | | | | | | | * 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.
* 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 Kylheku2025-01-171-1/+11
| | | | | | | | | | | | | * 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.
* lop: don't insert args when metas present.Kaz Kylheku2025-01-081-4/+8
| | | | | | | | | | | | | | | | | | | | | 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 Kylheku2024-12-201-2/+0
| | | | | | | | | | | | | * 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.

* compiler: update list of constant and effect-free functions.Kaz Kylheku2024-04-051-25/+28
| | | | | | | | | | | | | | | * stdlib/constfun.tl (%const-foldable-funs%): Numerous functions added, mostly new ones. (%effect-free-funs%): Indentation fixed. Some functions added, but also removed. We don't want anything in here that could take a functional argument. The optimizer will blindly a call to an effect-free function, if its result is not used, regardless of what the arguments are. It won't take into consideration that there is a functional argument, which could be a function that has a side effect, and that is called by the supposedly effect-free function. So for instance, sort is out; the comparison or key functions could have side effects. We could put these functions into a special category.

* tests: suppress warnings in seq.tl.Kaz Kylheku2024-03-083-37/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When tests/012/compile.tl compiles tests/012/seq.tl, there are now some compiler warnings due to constant expressions that throw. We introduce a new compiler option to suppress them, and then use it. * stdlib/comp-opts.tl: New file. The definitions related to compiler options are moved here out of compile.tl, so that optimize.tl can use them. * stdlib/compiler.tl (compile-opts, %warning-syms%, when-opt, *compile-opts*, opt-controlled-diag): Moved to comp-opts.tl. New constant-throws option added to compile-opts and %warning-syms%. (safe-constantp): Make the constant expression throws diagnostic conditional on the new option. * stdlib/optimize.tl: Load comp-opts file. (basic-blocks do-peephole-block): Make diagnostic about throwing situation subject to constant-throws option. * tests/012/seq.tl: Turn off constant-throws warning option before the ref tests that work with ranges. Fix: one of the expressions calls refs with the wrong number of arguments, which was unintentional. * txr.1: Document new diagnostic option.
* quips: new Lisp entry.Kaz Kylheku2024-02-181-0/+1
| | | | * quips.tl (%quips%): New dad humor.

| | | | | | * stdlib/compiler.tl (simplify-variadic-lambda): Use cons-count to find occurrences of the rest variable rather than flatten and count.
* compiler: take advantage of fixed @(end) match.Kaz Kylheku2024-02-081-2/+1
| | | | | | * stdlib/compiler.tl (simplify-variadic-lambda): Remove work-around where two patterns are combined with or, expressing it the way it wants to be.
* match: remove bad restriction from @(sme) and @(end).Kaz Kylheku2024-02-081-13/+5
| | | | | | | | | | | | | | | | | | | | | | | | The end pattern in @(sme) and @(end) does not have to be a list pattern, dotted or otherwise. It should support any pattern whatsoever for a single object, which should match the terminating atom. The documentation says that, though not very clearly; it is reworded also. * stdlib/match.tl (check-end): Remove this function, since the end pattern can be any pattern. (pat-len): Bugfix: we are using the meq function incorrectly. The object being compared against several alternatives must be the leftmost argument of meq. This bug prevents a pattern like @(evenp @x) to be correctly considered of length zero. (sme, end): Remove calls to check-end, and just refer to original end variable. * tests/011/patmatch.tl: New tests. * txr.1: clarify that the end pattern may be any pattern, which can match just the terminating atom or a possibly dotted suffix.
* compiler: inlined chain: simplify variadic lambdas.Kaz Kylheku2024-02-081-2/+15
| | | | | | | | | | | | | | | The opip syntax often generates lambdas that have a trailing parameter and use [sys:apply ...]. This is wasteful in the second and subsequent argument positions of a chain, because we know that only a single value is coming from the previous function. We can pattern match these lambdas and convert the trailing argument to a single fixed parameter. * stdlib/compiler.tl (simplify-variadic-lambda): New function. (inline-chain-rec): Try to simplify every function through simplify-variadic-lambda. The leftmost function is treated in inline-chain, so these are all second and subsequent functions.
* compiler: implement inlining for chain expressions.Kaz Kylheku2024-02-071-1/+34
| | | | | | | | | | | | | | | | | | | | The opip syntax and its variants transforms into chain expressions. Currently, we emit actual chain function calls, and so all the chain arguments that are lambda expressions have become closures. In this commit, an inlining optimization is introduced which turns some chain function calls into chained expressions. The lambdas are then immediately called, and so succumb to the lambda-eliminating optimization. * stdlib/compiler.tl (compiler comp-fun-form): Handle chain forms. At optimization level 6 or higher, if the form is eligible for the transform, perform it. (inline-chain-rec, can-inline-chain, inline-chain): New functions. * txr.1: Mention that *opt-level* 6 does this chain optimization.
* compiler: whitespace issue.Kaz Kylheku2024-02-071-1/+1

* compiler: optimizer must watch for throwing constant exprsKaz Kylheku2023-12-202-11/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have these issues, which are regressions: 1> (compile-toplevel '(/ 1 0)) ** expr-1:1: warning: sys:b/: constant expression (sys:b/ 1 0) throws ** /: division by zero ** during evaluation at expr-1:1 of form (sys:b/ 1 0) 1> (compile-toplevel '(let ((a 1) (b 0)) (/ a b))) ** /: division by zero ** during evaluation at expr-1:1 of form (compile-toplevel [...]) While the compiler's early pass constant folding is careful to detect constant expressions that throw, care was not taken in the optimizer's later constant folding which takes place after constant values are propagated around. After the fix: 1> (compile-toplevel '(let ((a 1) (b 0) (c t)) (if c (/ a b)))) ** expr-1:1: warning: let: function sys:b/ with arguments (1 0) throws #<sys:vm-desc: 9aceb20> 2> (compile-toplevel '(let ((a 1) (b 0) (c nil)) (if c (/ a b)))) #<sys:vm-desc: 9aef9f0> * stdlib/compiler.tl (compiler): New slot top-form. (compile-toplevel): Initialize the top-form slot of the compiler. The optimizer uses this to issue a warning now. Since the warning is based on analyzing generated code, we cannot trace it to the code more precisely than to the top-level form. * stdlib/optimize.tl (basic-blocks): New slot, warned-insns. List of instructions that have been warned about. (basic-blocks do-peephole-block): Rearrange the constant folding case so that as part of the pattern match condition, we include the fact that the function will not throw when called with those constant arguments. Only in that case do we do the optimization. We warn in the case when the function call does throw. A function rejected due to throwing could be processed through this rule multiple times, under multiple peephole passes, so for that reason we use the warned-insns list to suppress duplicate warnings.

* compiler: handle non-locally-exiting top-level forms.Kaz Kylheku2023-12-111-1/+4
| | | | | | | | | | | | | | * stdlib/compiler.tl (compile-file-conditionally): When evaluation of a compiled top-level form is not suppressed, there is a risk that it can terminate non-locally, via throwing an exception or performing a block return. The compilation of the file is then aborted. We can do better: using an unwind-protect, we can catch all non-local control transfers out of the form and just ignore them. The motivation for this is that it lets us compile files which call (return-from load ...), without requiring that it be written as (compile-only (return-from load ...)). Other things will work, like compiling a (load "foo") where foo doesn't exist or aborts due to errors.

A situation can occur whereby loading error.tl triggers loading some other files, which end up performing an expansion that needs sys:bind-mac-check: but that function has not yet been defined because error.tl has not yet loaded that far. The issue occurs when stdlib/place.tl is compiled before stdlib/error.tl. The compiled place.tl has a run-time dependency on functions in error.tl, because the compiled version of mac-param-bind and other forms relies on a run-time support function sys:bind-mac-check defined in stdlib/error.tl. * stdlib/error.tl (sys:dig): This function triggers the problem, but it's not the only cause. Here, the problem is because the (set ...) macro is used which triggers loading the stdlib/place module. That brings in the need for bind-mac-params. So here we use sys:setq instead. That is not a complete solution. The changes in eval.c are also required, because built-in macros like whilet expand to code that uses the (set ...) macro. Note how sys:dig uses whilet. (sys:bind-mac-check, sys:bind-mac-error): We move these functions above compile-warning. This addresses remaining circularity problem. The compile-warning function uses the catch macro which brings in stdlib/except.tl, which pulls in stdlib/op.tl due to its use of (do ...), which pulls in stdlib/place.tl. So if we already define sys:bind-mac-check at that point, we are good. * eval.c: Sweep the file for almost all places where macros generate code that invokes (set <symbol> <value>) and replace that with (sys:setq <symbol> <value>) to eliminate the dependency on loading the stdlib/place.tl module. (me_def_variable, me_gun, me_while_until_star, me_case, me_whilet, me_mlet, me_load_for, me_pop_after_load): In all these macro expanders, use sys:setq rather than set in the generated code. * tests/019/load-hook.tl: Some test cases here look for a macro expansion containing (set ...), needing to be fixed to look for (sys:setq ...) due to the change in eval.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ref function is not defined in the documentation as an accessor, but there is a ref place. Unfortunately, deletion is broken: (del (ref x y)) does not store the new sequence back into place x, and so it does not work correctly for lists; if x is a list, it doesn't change. Various accessors are defined in terms of ref, as place macros, such as the first, second, third, ... accessors. This fixes the bug for them also; (del (second list)) must update list. * stdlib/place.tl (ref): Fix the delete-expander to fetch the clobber expander of the sequence place, and use the simple setter to put the edited sequence into that place. * tests/012/seq.tl: Test case, which breaks without this fix. Test the (second ...) place also, which is defined in terms of ref. * txr.1: Split documentation for ref and refset, mainly because one is an Accessor and one is a Function. Removing some discussions about the equivalences between DWIM brackets and ref; there are subtleties there not worth going into. Description of refset is simplified. We mention the possibility of del over a ref place; only in that case is the sequence itself required to be a place.
