* txr: support variable in postive match.Kaz Kylheku2018-05-221-0/+21
| | | | | | | | | | | | | In the @{var mod} syntax in the pattern language, allow mod to be a variable which contains a regex or integer, not just an integer or regex literal. * match.c (h_var): Check for modifier being a variable, and resolve it. * parser.y (modifiers): Allow a SYMTOK phrase. * txr.1: Documented.
* logcount: new function.Kaz Kylheku2018-05-181-0/+19

* linenoise: switch to wide characters, support Unicode.Kaz Kylheku2015-09-221-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (chk_wrealloc): New function. * lib.h (mem_t): Wrap with ifndef block. (MEM_T_DEFINED): New preprocessor symbol. (chk_wrealloc): Declared. * linenoise/linenoise.c (LINENOISE_MAX_DISP): Adjust to a reasonable value; just twice the number of abstract characters. The 8 factor had been chosen to cover the worst case that every character is mapped to a tab. (struct lino_state): Almost everything char typed turns to wchar_t. The TTY isn't referenced with Unix file descriptors, ifd and ofd, but abstract stream handles tty_ifs and tty_ofs. The ifs member isn't required any more since plain mode is handled via the tty_ifs stream. (mem_t): Declaration removed; now in linenoise.h.

* doc: break up long syntax.Kaz Kylheku2018-05-021-9/+14
| | | | | | | | * txr.1: The syntax synopses for the following functions and macros are too long and are awkwardly wrapped by man under 80 columns: make-time, make-time-utc, make-env, call-update-expander, call-clobber-expander and txr-if. Breaking up and shortening some identifiers.
* doc: fix recurring syntax formatting error.Kaz Kylheku2018-05-021-12/+12
| | | | | | * txr.1: I spotted a problem in the syntax synopsis of remq, remql and remqual. The same mistake was made in a few other places. remq* also had an error, though different.

* compiler: implement eliding of blocks.Kaz Kylheku2018-04-241-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is time-wasting to have a block in every function. In this patch we have the compiler eliminate blocks if it is obvious that they will not be the targets of any exits or continuation captures through any direct function calls. If a block contains only calls to library functions, and doesn't call certain functions, then it is removed. It is possible for this removal to be strictly wrong and different from interpreted code. This is true if the code enclosed in a block invokes a function indirectly or via a quoted symbol, and that function tries to return from the block or capture a continuation using that block as a prompt. Such a call doesn't prevent the block from being removed. For instance, this won't work in compiled code any more: (defun tricky (fun) (call fun)) (tricky (lambda () (return-from tricky 42))) The call function is considered safe; the (call fun) form doesn't prevent the block inside the tricky function from being removed. * share/txr/stdlib/compiler.tl (blockinfo): New struct. (env): New slot, bb. (env lookup-block, env extend-block): New methods. (%block-using-funs%): New global variable. (compiler comp-block): Implement the elision of the block based on what free functions are referenced in the body, and whether the block is referenced lexically. Also, bind the block in the environment using the bb member in the env structure. (comp-return-from): Lookup the block lexically and mark it as used. (system-symbol-p): New function. * txr.1: Document the rules for elision of blocks.
* New macro: load-time.Kaz Kylheku2018-04-231-0/+297
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is similar to the ANSI CL load-time-value. * eval.c (load_time_s, load_time_lit_s): New symbol variables. (op_load_time_lit, me_load_time): New static functions. (eval_init): Intern load-time symbol and sys:load-time-lit. Register the sys:load-time-lit special operator and load-time macro. * share/txr/stdlib/asm.tl (assembler parse-args): We must now allow the d registers to be the targets of a mov instruction, because load-time depends on being able to mutate the data vector, in order to turn the result of a calculation into a de facto literal. * share/txr/stdlib/compiler.tl (compiler): New member, lt-frags. (compile-in-toplevel): New macro. (compiler alloc-dreg): New method. (compiler compile): Handle sys:load-time-lit special form via comp-load-time-lit method. (compiler comp-load-time-lit): New method. (usr:compile-toplevel): Prepend the load-time assembly code fragments to the compiled assembly code. * vm.c (vm_set, vm_sm_set): Do not reject an attempt to modify the static data, since load-time now generates mov instructions targetting the d registers. * txr.1: Document load-time.
* Version 192.txr-192Kaz Kylheku2018-04-191-2/+2
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim, protsym.c: Regenerated.
* doc: continuations: compiled vs interpreted.Kaz Kylheku2018-04-191-1/+38
| | | | | | | | * txr.1: Turn the comparison with lexical closures into a named subsection instead of Notes. Add subsection about mutated lexical variables and continuations: how the behavior can differ between interpreted and compiled code. Point user to the hlet and hlet* macros.
* new macros: hlet, hlet*.Kaz Kylheku2018-04-191-0/+22
| | | | | | | | | | * lisplib.c (yield_set_entries): Add hlet and hlet* to autoload list. * share/txr/stdlib/yield.tl (hlet-expand): New function (hlet, hlet*): New macros. * txr.1: Documented.
* compiler: don't expand top-level forms twice.Kaz Kylheku2018-04-181-1/+7
| | | | | | | | | | * share/txr/stdlib/compiler.tl (usr:compile-toplevel): Support optional parameter indicating that no expansion is required. (usr:compile-file): Call compile-toplevel with a t argument for the new expanded-p parameter, so no further expansion takes place. * txr.1: Document new optional parameter of compile-toplevel.
* Version 191.txr-191Kaz Kylheku2018-04-101-2/+2

* doc: new package fallback use by printer.Kaz Kylheku2018-04-101-1/+3
| | | | | * txr.1: Update the description of how the printer avoids ambiguity when making use of the packag fallback list.
* doc: document new pub package.Kaz Kylheku2018-04-091-11/+32
| | | | | | * txr.1: Fix places which say that *package* is initialized to the user package. Under *package*, describe the pub package. Compat notes added.
* doc: vm-fun-p described.Kaz Kylheku2018-04-091-0/+22
| | | | * txr.1: Document vm-fun-p.
* compiler: implement with-compilation-unit macro.Kaz Kylheku2018-04-091-0/+35
| | | | | | | | | | | | * lisp.c (compiler_set_entries): Add with-compilation-unit to autoload symbols for compile module. * share/txr/stdlib/compiler.tl (usr:with-compilation-unit): New macro. (usr:compile-file): Use with-compilation-unit macro to dump warnings if a file is processed alone. * txr.1: Documented.
* doc: document force-flag.Kaz Kylheku2018-04-091-5/+92
| | | | | | * txr.1: Documented force-break and the altered return value of width-check. The existence of a stream's force flag is mentioned under width check.
* doc: document disassemble.Kaz Kylheku2018-04-091-0/+51
| | | | * txr.1: Adding description of disassemble function.
* doc: describe new ldiff.Kaz Kylheku2018-04-091-87/+160
| | | | | * txr.1: ldiff documentation moved under Sequence Manipulation and rewritten. Compatibility note added.
* doc: copy-paste errors in structs.Kaz Kylheku2018-04-081-3/+3
| | | | | | * txr.1: Fixed syntax synopsis under struct-type using structp. Improved some wording here. Fixed static-slot-home's syntax synopsis wrongly referring to static-slot-ensure.
* doc: document more about file compilation.Kaz Kylheku2018-04-081-0/+143
| | | | | * txr.1: Add descriptions of compile-file, compile-only and eval-only.
* doc: starting to document compilation.Kaz Kylheku2018-04-081-7/+286
| | | | | * txr.1: Description of load includes treatment of .tlo files. New major section on Lisp compilation.
* macro param lists: remove colon hack.Kaz Kylheku2018-04-041-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Going forward, when : appears as the argument of an optional parameter in destructuring, it is treated as an ordinary object, and not as "this argument is missing". That is now a feature of function calls only. Rationale: interferes with macros. For instance, the pattern (test : then else) doesn't correctly express the arguments of if, because (if x y :) eats the semicolon. The defaulting behavior is not useful because usually there is no default value for optional structure, other than nil. * eval.c (bind_macro_params): Only implement the colon hack under compatibility with 190. * share/txr/stdlib/place.tl (defplace gethash, defplace fun, defplace symbol-function, defplace symbol-macro, defplace symbol-value): Remove uses of : for defaulting the ssetter argument. This illustrates how useless the feature is for macro destructuring; all these just replace with nil. * txr.1: Clarify that macro parameter lists don't implement the colon trick. It was never explicitly specified that this is the case, but could have been inferred from the statements which indicate that macro parameter lists copy the features of function parameter lists. Added compat notes.
* doc: codify infinite looping behavior of each.Kaz Kylheku2018-03-301-0/+6
| | | | | | | | | * txr.1: the each, append-each and all other variants of operators exhibit inifite looping if the list of bindings is empty. In that case, the terminating condition that at least one list is empty, is never true. The behavior is consistent under compilation and interpretation, so let's just document it.
* doc: null char in str out stream: incorrect.Kaz Kylheku2018-03-301-4/+8
| | | | | | | * txr.1: The described behavior regarding null bytes output into string output streams is incorrect. In fact they are effectively dropped by the put-char operation. Let's not commit to any specific behavior. Also mention pseudo-null.
* doc: incorrect text in rlet exampleKaz Kylheku2018-03-301-3/+2
| | | | * txr.1: Example isn't about swapping variables.
* doc: mistake in ldiff example.Kaz Kylheku2018-03-301-1/+1
| | | | * txr.1: A let in the example should be let*.
* doc: fix too-wide-for-80-cols syntax synopses.Kaz Kylheku2018-03-291-3/+6
| | | | | * txr.1: defmacro, macrolet and mac-param-bind syntax synopses are too wide under 80 column "man txr": breaking up.
* packages: drop no-fallback-list interning restriction.Kaz Kylheku2018-03-091-30/+6
| | | | | | | | | | | | | Removing the restriction that qualified pkg:sym syntax may not cause interning to take place if pkg has a nonempty fallback list. This serves no purpose, only hindering the flexibility of the package system. * parser.y (sym_helper): When processing a qualified symbol, if the package exists, just intern it. * txr.1: Revise all text which touched on the removed rule, to remove all traces of it from the documentation.
* New function: bignum-len.Kaz Kylheku2018-03-061-0/+32
| | | | | | | | | * arith.c (bignum_len): Wew function. (arith_init): Register bignum-len intrinsic. * arith.h (bignum_len): Declared. * txr.1: Documented.
* bugfix: missing actions in reset-struct.Kaz Kylheku2018-02-281-1/+30
| | | | | | | | | | | | * struct.c (reset_struct): Perform the post-init actions are performed, not only the init actions. Also, catch exceptions and call finalizers, just like in a new structure instantiation. * txr.1: Document the requirements for finalizers being called by reset-struct, and clarify the issue of possible duplicate finalization registration. Add compat notes.
* doc: wrong pluralizations of "function".Kaz Kylheku2018-02-271-3/+3
| | | | | | * txr.1: Fix three unrelated occurrences of the same mistake: "functions is", in reference to a single function.
* Version 190.txr-190Kaz Kylheku2018-02-181-2/+2
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim, protsym.c: Regenerated.
* New listener feature: greedy evaluation feature.Kaz Kylheku2018-02-171-0/+69
| | | | | | | | | | | | | | | | * eval.c (eval_intrinsic_noerr): New function. * eval.h (eval_intrinsic_noerr): Declared. * parser.c (listener_greedy_eval_s): New symbol variable. (repl): Implement greedy evaluation loop, enabled by the *listener-greedy-eval-p* special. (parse_init): Intern the *listener-greedy-eval-p* symbol, storing it in the listener_greedy_eval_s variable. Register the symbol as a special variable. * txr.1: Documented *listener-greedy-eval-p* variable and the greedy evaluation feature that it controls.
* Lisp load function supports .txr files.Kaz Kylheku2018-02-161-23/+78
| | | | | | | | | | | | * eval.c (load): Instead of throwing error when a .txr file is opened, process it according to sensible requirements. * match.c (v_load): Store bindings in the current environment frame before evaluating Lisp, and then update afterward. This allows .txr files loaded from Lisp to continue matching with the current bindings and extend those bindings. * txr.1: Update documentation of load.
