| | | | | | | * autoload.c (expander_let_set_entries): The expander-let symbol is in the usr package, registered via autoload_set, so the array should be called name and not sys_name.

| | | | | | | | | | | | * autoload.c (load_args_set_entries, load_args_instantiate): New static functions. (autoload_init): Register new auto-loaded module "load-args". * stdlib/load-args.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: new compiler option log-levelKaz Kylheku2023-06-041-1/+1
| | | | | | | | | | | | | | | | | | With log-level, we can obtain trace messages about what file is being compiled and individual forms within that file. * autoload.c (compiler_set_entries): Intern the slot symbol log-level. * stdlib/compiler.tl (compile-opts): New slot, log-level. (%warning-syms%): Add log-level to %warning-syms%. Probably we need to rename this variable. (compile-file-conditionally): Implement the two log level messages.

* compiler: new function, clean-file.Kaz Kylheku2023-06-041-1/+1
| | | | | | | | | | | | | | | | This function simplifies cleaning, by allowing a file to be cleaned to be identified in much the same way as an input file to load or compile-file. * autoload.c (compiler_set_entries): The clean-file symbol is interned and becomes an autoload trigger for the compiler module. * stdlib/compiler.tl (clean-file): New function. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* bug: autoload issue affecting with-compilation-unitKaz Kylheku2023-06-031-0/+5
| | | | | | | | | | | | | | | When a (with-compilation-unit ...) form is compiled, it references the value of a certain special variable that is private to the compiler. This reference is correct, but the variable's symbol is not hooked up to trigger autoload. If the compiler module has not yet been loaded, and the compiled version of a with-compilation-unit form is evaluated, it will fail due to an unbound variable error. * autoload.c (compiler_set_entries): Add the sys:*in-compilation-unit* variable name to the autoload triggers for the compiler module.
* New macro: expander-let.Kaz Kylheku2023-05-281-0/+17

* New special operator: compiler-letKaz Kylheku2023-05-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | * eval.c (compiler_let_s): New symbol variable. (op_let): Recognize compiler-let for sequential binding. (do_expand): Traverse and diagnose compiler-let form. (eval_init): Initialize compiler_let_s and register the interpreted version of the operator. * stdlib/compiler.tl (compiler compile): Handle compiler-let form. (compiler comp-compiler-let): New method. (no-dvbind-eval): New function. * autoload.c (compiler-set-entries): Intern the compiler-let symbol in the user package. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* autoload: temporarily disable backward compat.Kaz Kylheku2023-04-091-0/+3
| | | | | | | | | | | | | | | | | | | | The purpose of this change is to help with the situation when an uncompiled stdlib is being used (.tl files, no .tlo) and txr is invoked with -C <num> to select compatibility mode with an old version. The problem with compatibility is that it potentially breaks the library due to the different behavior of some macros like caseql. Some test cases in the test suite use backwards compatibility, and sometimes it is necessary to run with the uncompiled test suite when debugging compiler work: situations when the compiler is too broken to build the library. * autoload.c (autoload_try): Temporarly set the opt_compat option to 0 (disabled) around autoload processing. Thus the loading of library code in source code form will not be adversely affected by any syntax or macro level backward compatibility hacks.
* compiler: implement unused warningKaz Kylheku2023-03-201-1/+2
| | | | | | | | | | | | | | | | * autoload.c (compiler_set_entries): Register slot symbol "unused". * stdlib/compiler.tl (compile-opts): New slot, unused. (%warning-syms%): List unused symbol. (env lookup-var): Support optional mark-used parameter, just like lookup-fun. (env unused-check): New method. (compiler comp-var): Pass t to mark-used parameter of lookup-var to register the use. (compiler (comp-let, comp-var)): Call unused-check method after sub-compilations are done to dump diagnostics about unused variables.
* compiler: compiler options mechanism.Kaz Kylheku2023-03-201-1/+11
| | | | | | | | | | | | | | | | | | | | | | | Introducing a compiler options system, so we can control diagnostics and such. We begin with three options for diagnosing shadowing. * autoload.c (compiler_set_entries): Register a structure name compiler-opts, a with-compile-opts function name, *compile-opts* variable name, and slots shadow-fun, shadow-var and shadow-cross. * stdlib/compiler.tl (compile-opts): New struct. (%warning-syms%): New macro. (*compile-opts*): New special variable. (when-opt, with-compile-opts): New macros. (opt-controlled-diag): New function. (env extend-var): Call extend-var* method instead of repeating code. (env extend-var*): Implement shadow-var and shadow-cross diagnostic options. (env extend-fun): Implement shadow-fun and shadow-cross diagnostic options.

* autoload: use weak hash to erase registrations.Kaz Kylheku2022-02-191-94/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In autoload the _set_entries functions are being called twice: the first time with a functional argument to associate symbols with that function, and then when the module is loaded, a second time with a nil argument to erase those associations. This is inefficient; some modules have many symbols to remove from a hash. What we can do is make the hash weak; associate the symbols with a function weakly, such that those entries lapse when the function becomes garbage. Lapsing of weak hash table entries during GC is more efficient than making numerous calls to remhash. We can use a separate strong hash table to hang on to the functions; when a module is instantiated, all we have to do is remove the instantiation function from the table. Then that function is reachable only as a weak value from the other tables. * autoload.c (autoload_reg_hash): New static variable. (place_instantiate, ver_instantiate, ifa_instantiate, txr_case_instantiate, with_resources_instantiate, path_test_instantiate, struct_instantiate, with_stream_instantiate, hash_instantiate, except_instantiate, type_instantiate, yield_instantiate, sock_instantiate, termios_instantiate, awk_instantiate, build_instantiate, trace_instantiate, getopts_instantiate, package_instantiate, getput_instantiate, tagbody_instantiate, pmac_instantiate, error_instantiate, keyparams_instantiate, ffi_instantiate, doloop_instantiate, stream_wrap_instantiate, asm_instantiate, compiler_instantiate, debugger_instantiate, op_instantiate, save_exe_instantiate, defset_instantiate, copy_file_instantiate, arith_each_instantiate, each_prod_instantiate, quips_instantiate, match_instantiate, doc_instantiate, pic_instantiate, constfun_instantiate): Remove set_fun argument and call to that function. (autoload_reg): Remove argument from instantiate function. Add the function to the autoload_reg_hash table, associated with the t symbol. (autoload_init_tables): Initialize autoload_reg_hash. Turn the existing symbol hashes into weak tables. Let's use weak or-semantics, so they don't hang onto uninterned symbols. (autoload_try): If a symbol resolves to a function, indicating a load might be required, we now must verify whether that is really the case by seeing whether the function exists in the autolod_reg_hash table. If so, we remove it from that table and do the load. * autoload.h (autoload_reg): Declaration updated. * gencadr.txr (cadr_register): Remove set_fun argument and call to that function. * cadr.c: Regenerated.
* lisplib: rename to autoload.Kaz Kylheku2022-02-181-0/+1148

(autoload_try_fun, autoload_try_var, autloload_try_slot, autoload_try_struct, autoload_try_keyword): Follow rename. * lisplib.h: Renamed to autoload.h. (lisplib_init): Renamed to autoload_init. * eval.c: Include autoload.h. (eval_init): Follow rename of lisplib_init. * gencadr.txr: include "autoload.h" * cadr.c: Regenerated.
