*	rel-path, path-equal: native Windows fixes.	Kaz Kylheku	2021-11-01	1	-19/+43
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The checks for native Windows are incorrect, plus there are some issues in the path-volume function. We cannot check for native Windows at macro-expansion time simply by calling (find #\\ path-sep-chars) because we compile on Cygwin where that is false. What we must do is check for being on Windows at macro-expansion time, and then in the "yes" branch of that decision, the code must perform the path-sep-char test at run-time. In the "no" branch, we can output smaller code that doesn't deal with Windows. * stdlib/copy-file.tl (if-windows, if-native-windows): New macro, which give a clear syntax to the above described testing. (path-split): Use if-native-windows. (path-volume): Use if-native-windows. In addition, fix some broken tests. The tests for a UNC path "//whatever" cannot just test that the first components are "", because that also matches the path "/". It has t be that the first two components are "", and there are more components. A similar issue occurs in the situation when there is a drive letter. We cannot conclude that if the component after the drive letter is "", then it's a drive absolute path, because that situation occurs in a path like "c:" which is relative. We also destructively manipulate the path to splice out the volume part and turn it into a simple relative or absolute path. This is because the path-simplify function deosn't deal with the volume prefix; its logic like eliminating .. navigations from root do not work if the prefix component is present. (rel-path): We handle a missing error case here: one path has volume prefix and the other doesn't. Also the error cases that can only occur on Windows are wrapped with if-windows to remove them at compile time.
*	path-equal: enable and fix failing tests.	Kaz Kylheku	2021-10-20	1	-2/+3
\| \| \| \| \| \| \| \| \|	* stdlib/copy-file.tl (path-simplify): If the incoming path's first component is "", it is absolute; in that case swallow any components that go above. * tests/018/path-equal.tl: Uncomment two previously failing tests.
*	path-equal: propagate fixes from rel-path.	Kaz Kylheku	2021-10-11	1	-12/+10
\| \| \| \| \| \| \|	* stdlib/copy-file.tl (path-equal): This function is based on rel-path and so suffers the same bugs. Retarget it to use the new functions and approach to volumes from rel-path, so it benefits from the fixes.
*	rel-path: multiple bugs for native Windows.	Kaz Kylheku	2021-10-11	1	-21/+55
\| \| \| \| \| \| \| \| \| \| \| \| \|	The first bug is that we are using the spl function with pat-sep-chars. But spl does not take a set of characters; we need the sspl function. Other bugs are handling drive letters or UNC paths properly on Windows. * stdlib/copy-file.tl (path-split, path-volume): New functions. (rel-path): Split path properly. Diagnose for all bad combinations of mismatching absolute/relative paths with or without a volume or incompatible volumes.
*	New path-equal function.	Kaz Kylheku	2021-10-10	1	-0/+14
\| \| \| \| \| \| \| \| \| \|	* lisplib.c (copy_file_set_entries): Add path-equal to autoload symbols. * stdlib/copy-file.tl (path-equal): New function. * tests/018/path-equal.tl: New file. * txr.1: Documented.
*	rel-path: refactor, fix diagnostic message.	Kaz Kylheku	2021-10-10	1	-32/+29
\| \| \| \| \| \| \|	* stdlib/copy-file.tl (path-simplify): New function. (rel-path): Get rid of macrolet by using macro-time expression; remove flet since canon is now path-simplify at the top level. Fix diagnostic.
*	license: reformat to fit 80 columns.	Kaz Kylheku	2021-08-16	1	-13/+13

*	file layout: moving share/txr/stdlib to stdlib.	Kaz Kylheku	2021-06-24	1	-0/+251
	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.
