*	file layout: moving share/txr/stdlib to stdlib.	Kaz Kylheku	2021-06-24	1	-123/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This affects run-time also. Txr installations where the executable is not in directory ending in ${bindir} will look for stdlib rather than share/txr/stdlib, relative to the determined installation directory. * txr.c (sysroot_init): If we detect relative to the short name, or fall back on the program directory, use stdlib rather than share/txr/stdlib as the stdlib_path. * INSTALL: Update some installation notes not to refer to share/txr/stdlib but stdlib. * Makefile (STDLIB_SRCS): Refer to stdlib, not share/txr/stdlib. (clean): In unconfigured mode, remove the old share/txr/stdlib entirely. Remove .tlo files from stdlib. (install): Install lib materials from stdlib. * txr.1: Updated documentation under Deployment Directory Structure. * share/txr/stdlib/{asm,awk,build,cadr}.tl: Renamed to stdlib/{asm,awk,build,cadr}.tl. * share/txr/stdlib/{compiler,conv,copy-file,debugger}.tl: Renamed to stdlib/{compiler,conv,copy-file,debugger}.tl. * share/txr/stdlib/{defset,doc-lookup,doc-syms,doloop}.tl: Renamed to stdlib/{defset,doc-lookup,doc-syms,doloop}.tl. * share/txr/stdlib/{each-prod,error,except,ffi}.tl: Renamed to stdlib/{each-prod,error,except,ffi}.tl. * share/txr/stdlib/{getopts,getput,hash,ifa}.tl: Renamed to stdlib/{getopts,getput,hash,ifa}.tl. * share/txr/stdlib/{keyparams,match,op,optimize}.tl: Renamed to stdlib/{keyparams,match,op,optimize}.tl. * share/txr/stdlib/{package,param,path-test,pic}.tl: Renamed to stdlib/{package,param,path-test,pic}.tl. * share/txr/stdlib/{place,pmac,quips,save-exe}.tl: Renamed to stdlib/{place,pmac,quips,save-exe}.tl. * share/txr/stdlib/{socket,stream-wrap,struct,tagbody}.tl: Renamed to stdlib/{socket,stream-wrap,struct,tagbody}.tl. * share/txr/stdlib/{termios,trace,txr-case,type}.tl: Renamed to stdlib/{termios,trace,txr-case,type}.tl. * share/txr/stdlib/{ver,vm-param,with-resources,with-stream}.tl: Renamed to stdlib/{ver,vm-param,with-resources,with-stream}.tl. * share/txr/stdlib/yield.tl: Renamed to stdlib/yield.tl. * share/txr/stdlib/{txr-case,ver}.txr: Renamed to stdlib/{txr-case,ver}.txr. * gencadr.txr: Update to stdlib/place.tl. * genman.txr: Update to stdlib/cadr.tl.

\| \| \| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:trace-redefine-check): Move the sys:untrace call before the warning throw. That throw doesn't return; it ends up transferring control to the continue catch, and so the untrace is skipped.

*	trace: refer usr:catch operator rather than sys:catch.	Kaz Kylheku	2018-04-08	1	-3/+3
\| \| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:trace, sys:untrace): Now that library code is being read in the sys package, catch refers to the sys:catch special form; we want the usr:catch macro here.
*	trace: bugfix: redefine check mustn't throw exceptions.	Kaz Kylheku	2018-04-08	1	-6/+10
\| \| \| \| \| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:trace-canonicalize-name): Don't call static-slot-home on something that might not be a struct type symbol. Otherwise the trace module will throw whenever some lookup is performed for a non-existent method. That means that when trace is loaded, it is impossible to define a method with defun.
*	stdlib: all code read under sys package.	Kaz Kylheku	2018-04-06	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Another part of the preparation for an upcoming change. All library code is now read in the sys package, so any symbols that are interned (local variables and whatnot) are in sys and will not be exposed to user code. We have to overcome some annoyances to achieve this: - We have to stay away from the symbols exp or var, because they are now sys:exp and sys:var with their special meaning. - Instances in which a symbol of the same name exists in both sys and usr present a problem; the plain symbol now is the usr one. For instance rplaca will refer to sys:rplaca, so a small amount of code has to explicitly use usr:rplaca. * Makefile (COMPILE_TL): Change to the sys package before compiling library code. * lisplib.c (lisplib_try_load): Bind package to the system package. * share/txr/stdlib/asm.tl, share/txr/stdlib/compiler.tl: Remove in-package macro invocation; we don't need this since all files are loaded or compiled in the sys package. * share/txr/stdlib/build.tl, share/txr/stdlib/cadr.tl, share/txr/stdlib/conv.tl, share/txr/stdlib/doloop.tl, share/txr/stdlib/error.tl, share/txr/stdlib/error.tl, share/txr/stdlib/except.tl, share/txr/stdlib/ffi.tl, share/txr/stdlib/getopts.tl, share/txr/stdlib/getput.tl, share/txr/stdlib/hash.tl, share/txr/stdlib/ifa.tl, share/txr/stdlib/keyparams.tl, share/txr/stdlib/op.tl, share/txr/stdlib/package.tl, share/txr/stdlib/path-test.tl, share/txr/stdlib/place.tl, share/txr/stdlib/pmac.tl, share/txr/stdlib/socket.tl, share/txr/stdlib/stream-wrap.tl, share/txr/stdlib/struct.tl, share/txr/stdlib/tagbody.tl, share/txr/stdlib/termios.tl, share/txr/stdlib/trace.tl share/txr/stdlib/txr-case.tl, share/txr/stdlib/type.tl, share/txr/stdlib/ver.tl, share/txr/stdlib/with-resources.tl, share/txr/stdlib/with-stream.tl, share/txr/stdlib/yield.tl: Deal with the various usr versus sys symbol issues.
*	trace: add missing copyright header.	Kaz Kylheku	2018-04-05	1	-0/+26
\| \| \| \|	* trace.tl: File was introduced in 2016, so 2016-2018.
*	trace: bugfix: spurious "previously traced" warning	Kaz Kylheku	2017-12-08	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	When a method is traced with (trace (meth class slot)), a spurious warning occurs. This is because the function is recorded in the trace hash first and then the hook is installed, and the hook is installed using the static-slot-ensure function which performs the trace warning check. * share/txr/stdlib/trace.tl (sys:trace): Swap the order: install the hook first, and then put the the previous function into the trace hash. Doing this in parallel with pset would also work.
*	trace: allow format and * functions to be traced.	Kaz Kylheku	2017-07-16	1	-2/+5
\| \| \| \| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:tr, sys:trfm): New variables, holding the and format functions. (sys:trace-enter, sys:trace-leave): Use format and * through the aliases, so we don't trigger infinite recursion if these are traced.
*	trace: wrong function printed in traces.	Kaz Kylheku	2017-03-24	1	-3/+4
\| \| \| \| \| \| \| \| \| \| \| \|	When tracing for two or more functions is enabled in a single trace form, the the function tracing hooks print the wrong name for all but the rightmost function. * share/txr/stdlib/trace.tl (sys:trace): Fix code which assumes that the each operator binds fresh lexical variables on each iteration. Bind a fresh lexical variable lex-n which copies the current value of the loop variable n, and refer to this lexical out of the tracing lambda.
*	trace: implement redefinition checks.	Kaz Kylheku	2017-03-17	1	-0/+15
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The tracing module should warn when traced functions or methods are being redefined, and stop tracing the original methods. * eval.c (trace_check): New function. Calls sys:trace-redefined-check if the trace module has been loaded, otherwise does nothing. (op_defun, op_defmacro): Call trace_check to have a warning issued for a redefined traced function or macro. * eval.h (trace_check): Declared. * lisplib.c (trace_loaded): New global variable. (trace_instantiate): Flip trace_loaded to t. * lisplib.h (trace_loaded): Declared. * share/txr/stdlib/trace.tl (sys:trace-redefine-check): New function. Checks two situations: traced function or method is redefined (neither old nor new is traced any longer), and traced method is overridden (base method continues to be traced, override is not traced). * struct.c (static_slot_ensure): Do a trace check here, taking care of defmeth.
*	trace: detect inheritance, change name and warn.	Kaz Kylheku	2017-03-17	1	-10/+32
\| \| \| \| \| \| \| \| \| \| \| \|	When a method is traced that is actually derived from another struct type, we convert the (meth ...) name to refer to that type and issue a warning. * share/txr/stdlib/trace.tl (sys:trace-canonicalize-name): New function. (sys:trace): Canonicalize name, and trace the canonicalized name. Warn if it is different from the original name. (sys:untrace): Likewise for untracing.
*	Diagnose undefined functions in trace.	Kaz Kylheku	2016-11-19	1	-1/+3
\| \| \| \| \| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:trace): If symbol-function returns nil, throw exception. * txr.1: Document the behavior, along with return values of trace and untrace, and the tolerance of untrace to bad arguments.
*	Bugfix: cannot untrace individual method.	Kaz Kylheku	2016-11-19	1	-1/+1
\| \| \| \| \|	* share/txr/stdlib/trace.tl (sys:trace-hash): Hash must be equal-based to correctly support compound places.
*	Adding function tracing support.	Kaz Kylheku	2016-10-29	1	-0/+50
	New variable trace-output, and macros trace and untrace. * lisplib.c (trace_set_entries, trace_instantiate): new static functions. (dlt_register): Register new functions to auto-load trace module. * share/txr/stdlib/trace.tl: New file. * txr.1: Documented.
