* getopts: autoload: opt-error not interned.Kaz Kylheku2021-06-301-1/+1
| | | | | | * lisplib.c (getopts_set_entries): Add opt-error to list of interned symbols. Without this, getopts throws sys:opt-error. Reported by Paul A. Patience.
* New function: path-search.Kaz Kylheku2021-06-291-1/+1
| | | | | | | | | | | | * lisplib.c (path_test_set_entries): Autoload on path-search. * stdlib/path-test.tl (path-search): New function. * tests/018/path-test.tl: New file. * txr.1: Documented. * stdlib/doc-lookup.tl: Updated.
* constantp: fully expand; recognize functions.Kaz Kylheku2021-06-281-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the constantp function dramatically. It now performs a full expansion of its argument, and recognizes all of the constant foldable functions that the compiler recognizes. * eval.c (const_foldable_s): New symbol variable. (const_foldable_hash): New static variable. (constantp_noex): Look up function in the hash table of const foldable functions, including in the case when it appears in a dwim form as in [+ 2 2] which is (dwim + 2 2). In this case, recursively check the arguments for constantp_noex. We get the hash table of foldable functions from the sys:%const-foldable% variable, which comes from an autoloaded module. (constantp): Fully expand the input form, not just m macroexpand. (eval_init): Register the const_foldable_s variable. * lisplib.c (constfun_instantiate, constfun_set_entries): New static functions. (lisplib_init): Register auto-loading of constfun module via new static functions. * stdlib/compiler.tl; Load the constfun module if %const-foldable% is not defined. (%const-foldable-funs%, %const-foldable%): Removed from here. * stdlib/constfun.tl: New file. (%const-foldable-funs%, %const-foldable%): Moved here. * txr.1: Documented changes to constantp.
* matcher: new looping macros.Kaz Kylheku2021-06-241-0/+1
| | | | | | | | | | | | | | * lisplib.c (match_set_entries): Autoload on new while-match, while-match-case and while-true-match-case symbols. * share/txr/stdlib/match.tl (while-match, while-match-case, while-true-match-case): New macros. * tests/011/patmatch.tl: Tests. * txr.1: Documented. * share/txr/stdlib/doc-syms.tl: Updated.
* New macro: flow.Kaz Kylheku2021-06-161-1/+1
| | | | | | | | | | | | | | | There has been interest in the community in a threading macro; a triviality which which applies the opip syntax to a value. Eschewing unusual glyph combinations like ->> and whatnot, I've chosen the English word flow for this. * share/txr/stdlib/op.tl (flow): New macro. * lisplib.c (op_set_entries): Set up autoload for flow. * txr.1: Documented. * share/txr/stdlib/doc-syms.tl: Updated.

* matcher: new "each-match family" of macros.Kaz Kylheku2021-05-041-0/+3
| | | | | | | | | | | | | | | | | | * lisplib.c (match_set_entries): New autoload symbols: each-match, append-matches, keep-matches, each-match-product, append-match-products, keep-match-products. * share/txr/stdlib/doc-syms.tl: Updated. * share/txr/stdlib/match.tl (each-match-expander): New function.

(compiler comp-let): Eliminate frames only at level 3. (compiler comp-lambda-impl): Lift load time at level 3. (compiler comp-arith-form): Constant-folding only at lvl 1. (compiler comp-fun-form): Algebraic substitutions and reductions and constant-folding only at level 1. (compiler comp-apply-call): Constant folding at level 1.

* matcher: add :match parameter macro.Kaz Kylheku2021-02-041-0/+6
| | | | | | | | | | | | | With this, we can do matching anywhere we are able to specify a function parameter list and a body, and we can specify ordinary arguments, which are inserted to the left of the implicit match. Plus, it specialy integrates with :key. * lisplib.c (match_set_entries): Autoload on :match. * share/txr/stdlib/match.tl (:match): New parameter macro. * txr.1: Documented.
* matcher: new @(with) operator.Kaz Kylheku2021-02-011-1/+1
| | | | | | | | | | | | * lisplib.c (match_instantiate): Ensure usr:with is interned. * share/txr/stdlib/match.tl (compile-with-match): New function. (compile-match): Wire in with operator. * tests/011/patmatch.tl: Test cases. * txr.1: Documented.
* matcher: rename @(let) to @(as).Kaz Kylheku2021-02-011-1/+1
| | | | | | | | | | | | | * lisplib.c (match_instantiate): Ensure usr:as is interned. * share/txr/stdlib/match.tl (compile-let-match): Rename to compile-as-match. (compile-match): Remove handling of let symbol; route as symbol to compile-as-match. * tests/011/patmatch.tl: Update all uses of let to as. * txr.1: Updated.

| | | | | * lisplib.c (place_set_entries): Fix misspelling of call-delete-expander entry: stray parenthesis.
* matcher: add lambda-match and defun-matchKaz Kylheku2021-01-161-0/+1
| | | | | | | * lisplib.c (match_set_entries): New autoload triggers. * share/txr/stdlib/match.tl (lambda-match, defun-match): New macros.
* matcher: add if-match and match-case.Kaz Kylheku2021-01-151-1/+1
| | | | | | | | * lisplib.c (match_set_entries): Add match-case and if-match autoload trigger symbols. * share/txr/stdlib/match.tl (if-match, match-case): New macros.
* matcher: fix semantics of empty @(all ...) match.Kaz Kylheku2021-01-151-0/+6
| | | | | | | | | | | | * lisplib.c (match_set_entries): Ensure usr:all* is interned. * share/txr/stdlib/match.tl (compile-all-match): When the operator is the existing all, we must listp as a guard, not consp, because an empty list must match vacuously by virtue of not containing any counterexample to the pattern. For situations when a vacuous empty match is not desired, we support the all* alternative operator, which uses consp. (compile-match): Wire in the all* operator.
* new: structural pattern matching.Kaz Kylheku2021-01-141-0/+18
| | | | | | | | * lisplib.c (match_instantiate, match_set_entries): New static functions. (lisplib_init): Register autoload using new statics. * share/txr/stdlib/match.tl: New file.

(opts add-opt, option-base add-opt): Support options that have the cumul flag set by accumulating list values. The code is different due to different amounts of encapsulation. The opts structure stores the raw opt-parsed objects, whereas option-base just takes the decoded values. (opthelp): Parse through the (cumul ...) type syntax, so cumulative options are printed in the help text the same way as if they were non-cumulative. * txr.1: Documented.

| | | | | | | | | | | | | | | | | | | | | | | | | | The new function only compiles a file if the output file doesn't exist or is out of date. In addition, both compile-file now deletes the output file if compilation fails, and has a documented return value. * lisplib.c (compiler_set_entries): Add autoload entry fro compile-update-file. (open-compile-streams): Accepts a third argument: a function to test the input stream against the output path. The output file is opened, and the streams are returned, only if that test function returns true. Also, a third element is returned: the output path. This lets the caller to know what to delete, if the output file must be deleted. (compile-file-conditionally): New internal function, formed from compile-file. Takes an extra argument, the test function to pass to open-compile-streams. Compilation is skipped if open-compile-streams returns nil. Internals reshuffled a bit. If compilation doesn't set the success flag, then the with-resources logic now removes the output file in addition to closing the output stream. Prior to setting the success flag, we flush the output stream. * txr.1: Documented new function, all return values, and deletion of output file on unsuccessful compilation.
