* path-equal: enable and fix failing tests.Kaz Kylheku2021-10-201-2/+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.
* pic: support parenthesis negative notation.Kaz Kylheku2021-10-191-1/+22
| | | | | | | | | | * pic.tl (add-neg-parens): New system function. (expand-neg-parens): New macro. (expand-pic): New numeric pattern with parentheses. Also suport escaping of parentheses. (pic): Recognize parenthesized numeric pattern here also. * tests/018/format.tl: New tests.
* pic: bug: handle ! in digit separator logicKaz Kylheku2021-10-181-1/+1
| | | | | * stdlib/pic.tl (comma-positions): Must also look for ! point if the . point is not found.
* pic: preserve decimal period in ### overflow fill.Kaz Kylheku2021-10-181-1/+4
| | | | | | | | | | | | | | | | | | * pic.tl (expand-pic-num): If the overflowing field specifies a decimal point other than in the rightmost position, then stick one into the fill pattern. The motivation for this is that it harmonizes with the digit separators. The new digit separator insertion logic will treat the # characters like digits, and requires the embedded decimal in order to work properly. Allowing digit separation to work in the fill pattern will make for better looking output in column displays. That's the same reason why we insert digit separators among leading zeros. * tests/018/format.tl: Overflow test cases updated in light of this requirement change. * txr.1: Documented.
* doc: doc-syms refresh.Kaz Kylheku2021-10-181-0/+1
| | | | * stdlib/doc-syms.tl: Updated.
* pic: new feature: digit-separating commas.Kaz Kylheku2021-10-181-3/+51
| | | | | | | | | | | | | | | | This allows for pic patterns like #,###,###.### which incorporate digit separating commas into the output. * stdlib/pic.tl (comma-positions, insert-commas, expand-pic-num-commas): New system functions. (expand-pic): Recogize comma as a character which can be escaped using the tilde. Recognize a more complicated numeric pattern with commas. If the matched token contains commas, treat it using expand-pic-num-commas. (pic): Propagate a copy of the new numeric pattern here, where it is used for separation into tokens. * txr.1: Documented.
* quips: five new ones: quippy day today.Kaz Kylheku2021-10-151-0/+5
| | | | | * stdlib/quips.tl: New quips about rights, Lisp smugness, macros and Reddit.
* path-equal: propagate fixes from rel-path.Kaz Kylheku2021-10-111-12/+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 Kylheku2021-10-111-21/+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 Kylheku2021-10-101-0/+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 Kylheku2021-10-101-32/+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.
* Version 271.txr-271Kaz Kylheku2021-10-051-1/+1
| | | | | | | | | | | | | | * RELNOTES: Updated. * configure (txr_ver): Bumped version. * stdlib/ver.tl (lib-version): Bumped. * txr.1: Bumped version and date. * txr.vim, tl.vim: Regenerated. * protsym.c: Likewise.
* awk: :fields specifies conversions.Kaz Kylheku2021-10-042-43/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * stdlib/awk.tl (sys:awk-compile-time): Slot field-names renamed to field-name-conv. (sys:awk-expander): Parse the new syntax which allows (sym fn) pairs with optional fn, creating a list of normalized items in the field-name-conv slot of the compile-time structure. (sys:awk-symac-let): Adjust the code to the pair representation in field-name-conv. (sys:awk-field-name-code): New function for generating the field conversion code. (awk): Now that we have two optional pieces of code to wrap around p-actions form, we factor that out of the awk-lambda, to a series of conditional assignments. Here we handle the generation of the field conversionns. * conv.tl (sys:conv-expand-sym): New macro, used in sys:awk-field-name-code and sys:conv-let. (sys:conv-let): Simplify with sys:conv-expand-sym. Drop optional argument from i; it connects with no documented feature, and is not usable from fconv. * tests/015/awk-fields.tl: New tests. * txr.1: Updated, including cruft in fconv documentation. Change-Id: Ie42819f58af039fdbcdb1ae365c89dc1add55c93
* ffi: add cptr-carray function.Paul A. Patience2021-10-021-0/+1
| | | | | | | | | | | * ffi.c (cptr_carray): New function. (ffi_init): Register cptr-carray intrinsic. * ffi.h (cptr_carray): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* awk: new :fields feature for named fields.Kaz Kylheku2021-10-011-30/+48
| | | | | | | | | | | | | * stdlib/awk.tl (sys:awk-compile-time): New slot, field-names. (sys:awk-expander): Validate and store field-names into compile-time structure. (sys:awk-symac-let): New macro. (awk): Wrap sys:awk-symac-let around code to generate field name macros. * tests/015/awk-fields.tl: New file. * txr.1: Documented.
* compiler: peephole: recalc and rescan in a few more cases.Kaz Kylheku2021-09-301-0/+9
| | | | | | * stdlib/optimize.tl (basic-block peephole-block): In a few more cases, we should be setting the recalc flag to recalculate liveness, and adding some block to the rescan list.
* compiler: fix up linkage and recalc liveness in one peephole case.Kaz Kylheku2021-09-301-8/+11
| | | | | | | | * stdlib/optimize.tl (basic-blocks peephole-block): Rearrange the code a bit so we don't calculate the xbl, which potentially performs the cut-block, if there is no ybl. We set the bb.recalc flag since we may have cut a block into two and have redirected a jump, and also update the links for that reason.
* compiler: eliminate some redundant hash lookups.Kaz Kylheku2021-09-301-11/+12
| | | | | | | * stdlib/optimize.tl (basic-blocks thread-jumps-block, basic-blocks peephole-block): Streamline various cases of [bb.hash jlabel] being wastefully called twice to look up the same block referenced by the same label.
* compiler: eliminate basic-block next-block method.Kaz Kylheku2021-09-301-23/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The next-block method performs a linear search through the basic block list, which is physically ordered, to find the physically next block. This is actually not needed in several places that use the method; they want the logically next block, which is nil if the last instruction of the current doesn't potentially fall through to the next block. In the one place where we need the physical next block, in the elim-next-jump method, the caller can dynamically provide this, since it walks the list. * stdlib/optimize.tl (basic-block next-block): Method removed. (basic-block link-graph): We revise the logic here a little bit. All of the cases now consistently use the mechanism of setting link-next to nil to indicate that they don't fall through to the next block. The special case handling of the close instruction is clearer. (basic-block (thread-jumps-block, peephole-block)): Several cases here referred to the physically next block via the next-block method. This can be replaced by just using the next pointer, which will be the same. (basic-blocks elim-next-jump): This method now takes the next block as an argument, since there is no next-block method it can call to get the physcally next block. The argument is guaranteed non-null, so we don't need the .? null-safe slot access syntax. (basic-blocks elim-dead-code): Iterate over the next blocks simultaneously, and pass the next block into elim-next-jump. We no longer iterate over the last block, which has no physical next block.
* compiler: cosmetic: merge set assignments.Kaz Kylheku2021-09-301-7/+7
| | | | | | * stdlib/optimize.tl (basic-blocks join-block): Merge set forms into one. (basic-blocks elim-dead-code): Likewise.
* compiler: improvement in next-block linking.Kaz Kylheku2021-09-291-3/+3
| | | | | | | * stdlib/optimize.tl (basic-blocks link-graph): Do not search the entire list for a block's successor. Iterate over the cdr of the list in parallel, so that the next block is directly available at each iteration.
* compiler: remove impossible cases in jump threading.Kaz Kylheku2021-09-291-8/+4
| | | | | | | | | | | | | | * stdlib/optimize.tl (basic-blocks thread-jumps-block): There can't be any instructions in a basic block after an if or ifq, so in these cases, jrest is always nil. Let's ignore that nil efficiently with @nil, and get rid of the cut-block branches of the code. There is a similar case in peephole-block, but the target of the jump is an (end ...) which doesn't necessarily end a basic block. I temporarily put in an (assert (null jrest)), and, surprisingly, it never went off during a rebuild of the library or running of the test case. Still, only a jend ends a basic block; it would not be correct to simplify it like these two cases in thread-jumps-block.
* compiler: peephole: merge basic blocks when jmp removed.Kaz Kylheku2021-09-291-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | When a jmp instruction is removed from (necessarily) the end of a basic block, that basic block can be merged with the next one, and marked for re-scanning. A test case where this eliminates wasteful register-register move instruction is (match #(@a) #(3) a). * stdlib/optimize.tl (basic-blocks): New slot, tryjoin. (basic-blocks join-block): Null out the instruction list of the joined block. This helps if we do this during peephole processing, because it happens in the middle of an iteration over a list of blocks which can still visit the next block that has been merged into its predecesor; we don't want to be processing instructions that are no longer relevant. (basic-blocks peephole-block): In the one case where a conditional instruction is deleted from the end of the basic block, we add the block to the rescan list, and also to the tryjoin list. If the block can be merged with the next one, that can create more opportunities for peephole optimization. (basic-blocks peephole): Use zap in a few places to condense the logic of sampling a state variable that needs to be nulled out. Add the processing of the tryjoin list: pop basic blocks from the list, and try to merge them with their successor, if possible. We handle cases here where the next block could itself be in tryjoin. Also, if we join any blocks, we set the recalc flag to recalculate the liveness info.
* compiler: code clean-up in peephole optimizer.Kaz Kylheku2021-09-281-5/+5
| | | | | | | | | | | * stdlib/optimize.tl (basic-blocks peephole-block): When we match a branching instruction, including jend, we know that's the end of the basic block. So there is no need to splice the (rest insns) into the output; let's get rid of that. On the other hand, there is also no need to have a specific pattern match for the end of the list such as ((jmp @label)). This costs extra cycles to validate. Let's consistently match these basic-block terminating instructions using prefix patterns like ((jmp @label) . @nil)).
* quips: one in French.Kaz Kylheku2021-09-261-0/+1
| | | | * quips.tl: New quip.
* New variable: *child-env*.Kaz Kylheku2021-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This specifies the environment to be used for executing programs. * stream.c (open_subprocess, run): Check *child-env* variable and if other than t, then install the environment before execvp. In the spawn-based version of run, we save and restore the environment around the spawn call, if *child-env* is in effect. * sysif.c (child_env_s): New symbol variable. (exec_wrap): If *child-env* is other than t, then save the environment in a list, and install the specified environment before calling execvp. If that function returns, restore the environbment. * sysif.h (child_env_s): Declared. (child_env): New macro. * tests/018/process.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: replace-env.Kaz Kylheku2021-09-251-0/+1
| | | | | | | | | | | | | | | | | | | Using this new function together with env, it's now possible to save the set of environment variables, clobber it to a specified set (possibly empty) and then restore it. Useful for improved security in running child processes. * lib.[ch] (chk_substrdup_utf8): New function. * sysif.c (replace_env): New function. (sysif_init): Register replace-env intrinsic. * sysif.h (replace_env): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* path access tests: use real credentials.Kaz Kylheku2021-09-251-13/+13
| | | | | | | | | | | | | | | | | The various accessibility functions like path-writable-to-me should use the real credentials, the same way that the POSIX access function does. This makes them much more useful and secure in setuid programs, since they answer the question "does the underlying user, without these elevated privileges, have this access". * stdlib/path-test.tl (path-mine-p): Use getuid, not geteuid. (path-my-group-p): Use getgid, not getegid. (sys:path-access, path-private-to-me, path-strictly-private-to-me): Use getuid, getgid and rename euid variable to uid. * txr.1: Updated.
* path-search: rewrite in C with saner semantics.Kaz Kylheku2021-09-251-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The new function: - just returns the name if it contains path name components. - returns nil if the name is "." or "..". - tests for existence only, not permission to execute. * lisplib.c (path_test_set_entries): Do not auto-load path-test module on the path-search symbol, since it is no longer implemented there. * stdlib/path-test.tl (path-search): Function removed. * stream.c (path_var_sep_char): New global variable. (path_search): New function. (detect_path_separators): Also set path_var_sep_char to semicolon on Cygnal. (stream-init): Register path-search intrinsic here now. * stream.h (path_var_sep_char, path_search): Declared. * tests/018/path-test.tl: New tests. * txr.1: Documentation revised for path-search.
* New variants of each operator for sum and product.Kaz Kylheku2021-09-233-1/+92
| | | | | | | | | | | | | | | | | | | | | | | | | * lisplib.c (arith_each_instantiate, arith_each_set_entries): New functions. (each_prod_set_entries): Add sum-each-prod, sum-each-prod*, mul-each-prod and mul-each-prod* as autoload triggers for each-prod.tl, where those macros are now defined. (lisplib_init): Register autoloading of arith-each.tl via the two new functions. * stdlib/arith-each.tl: New file. * stdlib/each-prod.tl (sys:expand-each-prod*): Handle sum-each-prod* and mul-each-prod* in the same way, by mapping to their parallel binding counterparts. (sys:expand-arith-each-prod): New function. (sym-each-prod, mul-each-prod, sum-each-prod*, mul-each-prod*): New macros. * tests/016/arith.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* math: quantile estimator using P-Squared algorithm.Kaz Kylheku2021-09-221-0/+1
| | | | | | | | | | | | | | | | | | | * Makefile (psquare.o): New object file. * arith.c (psq_ops): New static structure. (quant_fun): New static function. (quantile): New function. (arith_init): Register quantile intrinsic. * arith.h (quantile): Declared. * psquare.c, psquare.h: New files. * tests/016/arith.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: reduce single-arg logior and logand.Paul A. Patience2021-09-141-1/+1
| | | | | * stdlib/compiler.tl (compiler comp-fun-form): Reduce single-argument logior and logand calls to just the argument.
* defset: add set-mask and clear-mask.Paul A. Patience2021-09-145-24/+35
| | | | | | | | | | | | | | | | | | | | * stdlib/defset.tl (set-mask, clear-mask): New update macros. * stdlib/optimize.tl (calc-liveness): Use the new macros. * stdlib/socket.tl (sys:str-inaddr-net-impl, str-in6addr-net): Same. * stdlib/termios.tl (set-iflags, set-oflags, set-cflags, set-lflags, clear-iflags, clear-oflags, clear-cflags, clear-lflags): Same. * lisplib.c (defset_set_entries): Add set-mask and clear-mask to autoload symbols for defset. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: fix random perturbance in reg allocation.Kaz Kylheku2021-09-141-2/+2
| | | | | | | | | | | | | | | At optimization level 2 or higher, an issue occurs whereby code generation exhibits instabilities. The same code is compiled slightly differently (but not incorrectly) depending on irrelevant circumstances, due to some different registers being used. * stdlib/compiler.tl (compiler eliminate-frame): Do not free the newly allocated t-registers inside a dohash loop. We have a separate list of them in order; just hand that off to free-tregs. The dohash loop is not ordered, because it traverses a hash, which is keyed by object identities; i.e. machine addresses assigned by memory allocation.
* ffi, sockets: add sock-opt and sock-set-opt.Paul A. Patience2021-09-122-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new sock-opt and sock-set-opt functions are wrappers around getsockopt and setsockopt, respectively. All POSIX socket options are registered. Platform-specific options may be added in the future. * ffi.c (sock_opt, sock_set_opt): New functions. (ffi_init): Register sock-opt, sock-set-opt, sol-socket, ipproto-ip, ipproto-ipv6, ipproto-tcp, ipproto-udp, so-acceptconn, so-broadcast, so-debug, so-dontroute, so-error, so-keepalive, so-linger, so-oobinline, so-rcvbuf, so-rcvlowat, so-rcvtimeo, so-reuseaddr, so-sndbuf, so-sndlowat, so-sndtimeo, so-type, ipv6-join-group, ipv6-leave-group, ipv6-multicast-hops, ipv6-multicast-if, ipv6-multicast-loop, ipv6-unicast-hops, ipv6-v6only, tcp-nodelay. * lisplib.c (sock_set_entries): Add sock-opt and sock-set-opt. * stdlib/socket.tl (sock-opt): Define as syntactic place. * tests/014/socket-misc.tl: New cases, for sock-opt. (set-and-get): New macro. * txr.1: Documented. Also, mention that sock-bind enables so-reuseaddr. * stdlib/doc-syms.tl: Updated.
* sockets: remove excess apostrophe in sock-peer.Paul A. Patience2021-09-111-1/+1
| | | | | * stdlib/socket.tl (sock-peer): Remove excess apostrophe in getter.
* matcher: use function for match and match-ecase error.Kaz Kylheku2021-09-101-2/+8
| | | | | | | * stdlib/match.tl (match-pat-error, match-error): New functions. (match, match-ecase): Generate more compact code which just calls match-pat-error rather than throwf, and doesn't contain any string literals.
* exceptions: hack to store errno in string object.Kaz Kylheku2021-09-071-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic idea: when we throw an exception that pertains to a system error which has an errno code, we can stick the errno into the memory area of the character string, into the wchar_t that immediately follows the null terminator. We can do this because strings track their actual allocation size. A pair of setter/getter functions to set and retrieve this value are provided, and all functions in the code which can set such a code are updated to do so, simply by calling the newly added uw_ethrowf that drop-in replaces for uw_throwf. * lib.[ch] (string_set_code, string_get_code): New functions. * unwind.[ch] (uw_ethrowf): New function. * eval.c (eval_init): Register string-set-code and string-get-code intrinsics. * ftw.c (ftw_wrap): Switch to uw_ethrowf. * parser.c (open_txr_file): Likewise. * socket.c (dgram_overflow): Store the ENOBUFS error in errno, and use uw_ethrowf instead uw_throwf. (dgram_get_byte_callback, dgram_flush, sock_bind, to_connect, open_sockfd, sock_connect, sock_listen, sock_accept, sock_shutdown, sock_timeout, socketpair_wrap): Switch to uw_ethrowf. * stream.c (dev_null_get_fd, stdio_maybe_read_error, stdio_maybe_error, stdio_close, pipe_close, open_directory, open_file, open_fileno, open_tail, fds_subst, open_subprocess, open_command, remove_path, rename_path, tmpfile_wrap, mkdtemp_wrap, mkstemp_wrap): Switch to uw_ethrowf. * sysif.c (mkdir_wrap, ensure_dir, chdir_wrap, getcwd_wrap, rmdir_wrap, mknod_wrap, mkfifo_wrap, chmod_wrap, do_chown, symlink_wrap, link_wrap, readlink_wrap, close_wrap, val exec_wrap, stat_impl, do_utimes, pipe_wrap, poll_wrap, getgroups_wrap, setuid_wrap, seteuid_wrap, setgid_wrap, setegid_wrap, setgroups_wrap, getresuid_wrap, setresuid_wrap, setresgid_wrap, crypt_wrap, uname_wrap, opendir_wrap, getrlimit_wrap, setrlimit_wrap): Likewise. * termios.c (tcgetattr_wrap, tcsetattr_wrap, tcsendbreak_wrap, tcdrain_wrap, tcflush_wrap, tcflow_wrap): Likewise. * tests/018/errno.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* string-finish: new function.Kaz Kylheku2021-09-071-0/+1
| | | | | | | | | | | | * eval.c (eval_init): Register string-finish intrinsic. * lib.c (string_finish): New function. * lib.h (string_finish): Declared. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* ffi: ffi macro uses load-time.Kaz Kylheku2021-09-061-1/+1
| | | | | | | | | | | | | | | A number of functions take an argument which is a ffi type. Typically, this argument is produced using by a ffi-type-compile call which is produced by the ffi macro. But this ffi-type-compile call is invoked at run time, each time such a function is called. A solution for this is to have the ffi macro hoist the compilation to load time. * stdlib/ffi.tl (ffi): Add load-time wrapping to generated expression. * txr.1: Updated correspondence between (ffi ...) form and equivalent (ffi-type-compile form).
* ffi: add socklen-t type.Paul A. Patience2021-09-061-17/+18
| | | | | | | | | | * ffi.c: Include <sys/socket.h> if we HAVE_SOCKETS. (ffi_init_extra_types): Initialize socklen-t type if we HAVE_SOCKETS. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* load: new macros push-after-load and pop-after-load.Kaz Kylheku2021-09-031-0/+2
| | | | | | | | | | | | | * eval.c (me_push_after_load, me_pop_after_load): New static functions. (eval_init): Register push-after-load and pop-after-load intrinsic macros. * tests/019/load-hook.tl: Tests for correct expansion. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New function: delcons.Kaz Kylheku2021-09-021-0/+1
| | | | | | | | | | | | * eval.c (eval_init): Register delcons intrinsic. * lib.[ch] (delcons): New function. * tests/010/cons.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* load: new *load-hooks* feature.Kaz Kylheku2021-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *load-hooks* lets a .txr, .tl or .tlo file specify actions to be taken when the loading of that file completes, whether normally or via an exception. They are also honored by process exit. For instance, with this, we can have a Lisp file that behaves like a script which cleans up after itself (e.g. removing temporary files) even if it is not run as a stand-alone program, but invoked via (load ...). Because it's not a stand-alone program, it cannot simply use the at-exit-call mechanism. The unwind-protect operator could be used, but it's inconvenient because it protects a single form. The *load-hooks* feature in effect protects all the top level forms of a load, similarly to unwind-protect. Also, unwind-protect does not guard against a process exit. (However, *load-hooks* does not guard against an abnormal exit, only normal termination). * eval.c (load_hooks_s): New symbol variable. (run_load_hooks): New function. (run_load_hooks_atexit): New static function. (load): bind *load-hooks* to nil around load. Implement the hooks processing via run_load_hooks, taking care to pass the load-time dynamic environment that has already been undone. (eval_init): Initialize load_hooks_s and register the *load-hooks* variable. Register run_load_hooks_atexit with atexit, so the current value of *load-hooks* is processed on process exit. * eval.h (load_hooks_s, run_load_hooks): Declared. * match.c (v_load): Similar changes as in load. * txr.c (txr_main): Run the load hooks with run_load_hooks immediately after processing the .txr or .tl file, before entering the listener. * tests/019/load-hook.tl: New directory and file * tests/load-hook.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* compiler: fix output path of compiled files.Paul A. Patience2021-09-011-1/+1
| | | | | | | | | | | The open-compile-streams function was calling trim-right with the arguments in the wrong order, resulting in an output path equal to the suffix of the input path. Regression introduced in 8d8fee2e506806d9c117b17432ef3a5ec0d6f457. * stdlib/compiler.tl (open-compile-streams): Swap in-path and suff arguments in trim-right call.
