* hashing: overhaul part 1.Kaz Kylheku2018-07-046-121/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hashing of buffers and character strings is being replaced with a seedable hash, providing a tool against denial of service attacks against hash tables. This commit lays most of the groundwork: most of the internal interface changes, and a new hashing implementation. What is missing is the mechanisms to do the seeding. * hash.c (struct hash_ops): Hash operation now takes a seed argument of type ucnum. (struct hash): New member, seed. (hash_str_limit): Default value changed to INT_MAX. A short value opens the gateway to an obvious collision attack whereby strings sharing the same 128 character prefix are entered into the same hash table, which will defeat any seedings strategy. (randbox): New static array. Values come from the Kazlib hash module, but are not used in exactly the same way. (hash_c_str, hash_buf): Now take a seed argument, and are rewritten. (equal_hash): Takes a seed, and passes it to hash_c_str, hash_buf and to recursive self calls. (eql_hash_op): New static function. Adapts the eql_hash operation, which doesn't take a seed, to the new interface that calls for a seed. (obj_eq_hash_op): Take a seed; ignore it. (hash_hash_op): Take a seed, pass it down to equal_hash. (hash_eql_ops): Wire hash functiono pointer to eql_hash_op instead of eql_hash. (make_hash): For now, intialize the hash's seed to zero. (make_similar_hash): Copy original hash's seed. (gethash_c, gethash_e, remhash): Pass hash table's seed to the hashing function. (hash_equal): Pass a seed of zero to equal_hash for now; this function will soon acquire an optional parameter for the seed. * hash.h (equal_hash): Declaration updated. * lib.c (cobj_handle_hash_op): Take seed argument, pass down. * lib.h (cobj_ops): Hash operation now takes seed. (cobj_eq_hash_op, cobj_handle_hash_op): Declarations updated. * struct.c (struct_inst_hash): Take seed argument, pass down. * tests/009/json.expected: Updated, because the hash table included in this output is now printed in a different order.
* doc: block* isn't elided.Kaz Kylheku2018-06-281-0/+4
| | | | | * txr.1: Make it clear that block* is not subject to progn-conversion.
* awk: bugfix: block optimized away by compiler.Kaz Kylheku2018-06-281-1/+1
| | | | | | | | | | | This breaks the (next) awk macro, breaking awk expressions which want to short-circuit to the next record. * share/txr/stdlib/awk.tl (sys:awk-state loop): The :awk-rec block is being optimized away by the compiler because it doesn't contain any direct function calls to functions that are not in the standard library. We must use block*, which isn't subject to this optimization.
* genman: use hash function written in Lisp.Kaz Kylheku2018-06-281-2/+6
| | | | | | | | | | | Planning to support seeded hashing, so the behavior of the hashing function will change. But we need a stable hash for the section URL's in the HTML doc; so let's preserve the existing function as Lisp code. * genman.txr (hash-str): New string hashing function. This behaves like the existing hash-equal behaves on 32 bits. (hash-title): Use hash-str instead of hash-equal.
* ffi: use existing local instead of struct access.Kaz Kylheku2018-06-251-4/+4
| | | | | | * ffi.c (ffi_closure_dispatch, ffi_closure_dispatch_safe): The nargs variable holds a copy of tfcl->nparam, so use it instead of accessing tfcl->nparam again.
* vm: replace open-coded ternary with max macro.Kaz Kylheku2018-06-251-4/+6
| | | | | | * vm.c (max): New macro. (vm_call, vm_apply, vm_gcall, vm_gapply): Use max macro in calculating args allocation.
* ftw: fix broken callback mechanism.Kaz Kylheku2018-06-251-1/+3
| | | | | | | * ftw.c (max): New macro. (ftw_callback): Allocate enough args for all five arguments. This bug went undetected when this was developed. A more recently added assertion in args.c caught this.
* hash: move ops into static structure + bug found.Kaz Kylheku2018-06-221-32/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The four hash operations (hash, equal, assoc and acons) are moved out of the hash instance and into a static table of operations. This means we have to go through one more indirection when calling them, but we save some space and shorten initialization. A bug is fixed here: the copy_hash function was only copying three out of these four functions; the equal operation was left uninitialized eposing the hash equality operation to corrupt behavior. Now that function just copies the hops pointer, so all is well. * hash.c (struct hash_ops): New struct type. (hash_ops_init): New macro. (struct hash): hash_fun, equal_fun, assoc_fun and assoc_new_c fun members removed. New member hops. (hash_eql_ops, hash_equal_ops): New static structures. (hash_equal_op): Compare the hops pointers rather than just the hash_fun: if two hashes have different hops pointers, they are different, period. Indirect through ops for calling equal fun and others. (hash_hash_op): Include the hops pointer in the hash, rather than the hash_fun pointer. (hash_print_op): Test for hash type (equal based or eql based) now done by comparing the hops pointer to one of the two static structures, rather than hash_fun to one of two functions. (make_hash, make_similar_hash, copy_hash): Initialize hops; remove initializations for the four functions. (gethash_c, gethash_e, remhash): Indirect through hops to invoke hash operations. (hash_uni, hash_diff, hash_isec): Incompatible hash check based on comparing hops pointer rather than hash_fun.
* hash: fix broken equality-of-two-hashes test.Kaz Kylheku2018-06-221-2/+2
| | | | | * hash.c (hash_equal_op): Fix broken logic that is supposed to push a cell onto the pending list: rplaca should be rplacd.
* load: do not record source location for compiled files.Kaz Kylheku2018-06-211-1/+6
| | | | | | | * parser.c (read_file_common): When reading a compiled file, turn off the rec_source_loc flag in the parser, since the forms are just data, and not source code for which we need error reporting.
* vm: rename identifiers that still use ftab terminology.Kaz Kylheku2018-06-211-13/+13
| | | | | | | | | * vm.c (struct vm_desc): Rename ftsz member to stsz. (struct vm_ftent): Renamed to struct vm_stent. (vm_make_desc, vm_make_destroy, vm_desc_mark, vm_stab, vm_invalidate_binding): Rename local ftsz variable to stsz, and follow the renames of struct members and of struct vm_ftent.
* vm: release cached bindings that become unbound.Kaz Kylheku2018-06-213-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | When a function binding is removed using fmakunbound, virtual machine descriptions hang on to the previously cached binding in the ftab. When the symbol is newly bound, virtual machine descriptions keep pointing to the old function. To solve this, we put the vm_desc structures into a global list and provide a function that fmakunbound calls to scrub all the VM descriptors of that binding. * eval.c (makunbound, fmakunbound): Call new vm_invalidate_binding function. * vm.c (struct vm_desc_links): New structure. (struct vm_desc): New member lnk, with links. (vmd_list): New static variable: circular list of all VM descriptors. (vm_make_desc): Insert new VM descriptor into list. (vm_desc_destroy): Remove VM descriptor from list. (vm_invalidate_binding): New function. * vm.h (vm_invalidate_binding): Declared.
* listener: fix crash in selection yanking.Kaz Kylheku2018-06-201-1/+1
| | | | | * linenoise/linenoise.c (yank_sel): Use wmalloc_fn because the size is being measured in characters rather than bytes.
* sysif: work around glibc warnings about makedev macros.Kaz Kylheku2018-06-082-7/+24
| | | | | | | | | | | | | | | | | The GNU C library is deprecating the practice of <sys/types.h> defining the makedev, major and minor macros. A loud, multi-line warning is issued for programs which include this header and then use the macros. The new way is to rely on the <sys/sysmacros.h> header instead. Of course, that might not exist. * configure (have_makedev): New variable. Upgrade the makedev test to try it with <sys/sysmacros.h> first, then fall back on <sys/types.h>. A new config macro HAVE_SYS_SYSMACROS_H is created in config.h if sysmacros exists. * sysif.c: If config.h defines HAVE_SYS_SYSMACROS_H to a nonzero value, then include <sys/sysmacros.h>.
* doc: deal with [ ] ambiguity in syntax sections.Kaz Kylheku2018-06-071-7/+27
| | | | | | | | * txr.1: In Syntax synopses, use the '[' and ']' notation to denote literal square brackets, since square brackets mean "optional". Updated Conventions sections to document this. Changes under operator drim, if, and and the from-list method.
* structs: slot access on non-struct: improve diagnosis.Kaz Kylheku2018-05-291-3/+11
| | | | | | | * struct.c (struct_handle_for_slot): New static function. (slot, maybe_slot, slotset): Use struct_handle_for_slot rather than struct_handle, for improved error message that reveals what slot name was requested.
* Version 197.txr-197Kaz Kylheku2018-05-276-518/+542
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* bugfix: fatal exception on missing .txr_history.Kaz Kylheku2018-05-272-2/+19
| | | | | | | | | | | The new abstraction layer used by linenoise throws exceptions, but linenoise excpects a null pointer when a file open fails. * parser.c (lino_open, lino_open8): Catch error exceptions and convert to null return, using new macros to reduce repetitive coding. * unwind.h (ignerr_begin, ignerr_end): New macros.
* compiler: fix broken block*.Kaz Kylheku2018-05-261-2/+2
| | | | | | | | | | | Compiling a block* fails with an exception: nil is accessed as a structure. * share/txr/stdlib/compiler.tl (comp-block): when compiling block*, nenv is nil; we must use env when compiling the name subexpression. Also, we can't use nenv when compiling the body. We must use nenv when it is available (block case) or else fall back on env (block* case).
* compiler/vm: renaming funvec.Kaz Kylheku2018-05-253-41/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtual machine's funvec will be used for global lexical variables also, so it is being renamed to symvec. Related structure members, functions and variables are also renamed. * share/txr/stdlib/asm.tl (disassemble): Print the table heading as syms: rather than funs:. Follow the rename of vm-desc-funvec to vm-desc-symvec. * share/txr/stdlib/compiler.tl (compiler): Slots fidx-cntr fidx and ftab are renamed to sidx-cntr, sidx and stab, resp. (compiler get-fidx): Renamed to get-sidx. (compiler get-funvec): Renamed to get-symvec. (compiler comp-setqf, compiler comp-catch, compiler comp-fun-form, usr:compile-toplevel): Follow rename. (list-from-vm-desc): Follow rename of sys:vm-desc-funvec. * vm.c (strut vm_desc): Members funvec and ftab renamed to symvec and stab. (vm_make_desc): Parameters and local variables renamed. Follow rename of struct members. (vm_desc_funvec): Renamed to vm_desc_symvec. (vm_desc_destroy, vm_desc_mark): Follow rename struct members. (vm_ftab): Renamed to vm_stab. (vm_gcall, vm_gapply): Follow rename of vm_ftab. (vm_init): Register renamed vm_desc_symvec function as sys:vm-desc-symvec.
* compiler: fix wrong free symbol calculations.Kaz Kylheku2018-05-251-10/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calculation of free symbols emanating out of let, let*, flet and labels is wrong, not taking into account the differences, respectively between let and let*, and between flet and labels. Compilation of lambda also has the same problem; variable references in initforms are considered free without regard for shadowing by earlier parameters. Another issue is the incorrect handling of special variables: special variable references are incorrectly being considered free in scopes where they are bound. * share/txr/stdlib/compiler.tl (compiler comp-let): For sequential bindings (let*), we must cull the prior variables from the list of free vars emanating out of each init form; these references do not emanate out of the binding construct. We pull the prior vars list out of the environment before binding the current variable so that it is not included in the list. Both special and lexical variables must be considered reference-capturing. (compiler comp-fbind): If compiling a recursive binding, cull the newly bound functions from the free references emanating from the local function bodies. A bug is fixed here that we were not referring to the correct list of symbols and so not taking into account the function references inside the local functions themselves at all. (compile comp-lambda): Build a correct list of free vars in relation to the initforms of optional parameters, taking account the scope, and that special variables capture references.
* doc: wrong eval-only description.Kaz Kylheku2018-05-251-4/+4
| | | | * txr.1: Revise incorrect semantic description of eval-only.
* doc: issues under Awk.Kaz Kylheku2018-05-251-1/+2
| | | | * txr.1: Wrong article "an local" and missing .codn line.
* Replace informality in command line help.Kaz Kylheku2018-05-241-1/+1
| | | | | | | * txr.1 (help): Someone reading the help text doesn't necessarily know that --help produced it; it can be read by someone in contexts where that same person didn't just obtain it by running txr --help.
* doc: document the --compiled option.Kaz Kylheku2018-05-241-20/+26
| | | | | * txr.1: Fold --compiled with --lisp into the same description.
* awk: bugfix: autoload on sys:awk-state.Kaz Kylheku2018-05-231-0/+4
| | | | | | | | | | | | The problem is that compiled code which uses the awk macro won't load because it invokes make-struct for the unknown sys:awk-state type. Interpreted code doesn't have the problem because it has to expand the awk macro from scratch to generate the make-struct call, and the awk macro triggers the autoload. * lisplib.c (awk_set_entries): Add sys:awk-state to autoload list for awk.tl.
* compiler: elide unused lexical functions.Kaz Kylheku2018-05-231-8/+16
| | | | | | | | | | This makes certain macros cheaper: macros which wrap code with numerous local functions, not all of which are expected to be used. * share/txr/stdlib/compiler.tl (compiler comp-fbind): Detect functions that are completely unused, and eliminate their code.
* compiler: streamline marking bindings used.Kaz Kylheku2018-05-231-19/+30
| | | | | | | | | | | | | | | NB: Accesses to lexical variables are not all marked used yet. * share/txr/stdlib/compiler.tl (binding): New slot, used. (sys:env lookup-var, sys:env lookup-fun, sys:env lookup-lisp1, sys:env lookup-block): Support optional Boolean argument which, if true, causes the lookup to mark the binding used. (compiler comp-return-from): Pass t to lookup-block, and remove code to mark used. (compiler comp-fun, compiler comp-fun-form): Pass t to lookup-fun to mark function used. (compiler comp-lisp1-value): Pass t to lookup-lisp1 to mark function used.
* txr: support variable in postive match.Kaz Kylheku2018-05-223-0/+27
| | | | | | | | | | | | | In the @{var mod} syntax in the pattern language, allow mod to be a variable which contains a regex or integer, not just an integer or regex literal. * match.c (h_var): Check for modifier being a variable, and resolve it. * parser.y (modifiers): Allow a SYMTOK phrase. * txr.1: Documented.
* logcount: new function.Kaz Kylheku2018-05-186-0/+121
| | | | | | | | | | | | | | | | | | This is in ANSI CL; potentially useful and hard to implement efficiently in user code. * arith.c (logcount): New function. * eval.c (eval_init): Register logcount intrinsic. * lib.h (logcount): Declared. * mpi/mi.c (s_mp_count_ones): New static function. (mp_count_ones): New function. * mpi/mpi.h (mp_count_ones): Declared. * txr.1: Documented.
* width: misleading error message.Kaz Kylheku2018-05-181-1/+1
| | | | | * arith.c (width): Fix incorrect name in type error diagnostic. There is no such function as integer-length.
* Version 196.txr-196Kaz Kylheku2018-05-186-142/+160
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* listener: Cygnal fix.Kaz Kylheku2018-05-181-1/+23
| | | | | | | | | | | | | | | | The standard input and output streams are in text mode on Cygnal, which interferes with the listener, because it draws input from streams. Let's hack it by Cygwin-specific code in linenoise. * linenoise/linenoise.c (struct lino_state): New members orig_imode and orig_omode, on Cygwin/Cygnal only. (enable_raw_mode): As part of enabling raw mode, use the Cygwin setmode function to put both descriptors in binary mode, saving their previous mode. (disable_raw_mode): Revert the previous mode of both descriptors, in reverse order in case they are the same descriptor.
* listener: Cygwin fix.Kaz Kylheku2018-05-183-14/+23
| | | | | | | | | | | | | | | | | | | | | | | | We cannot pass raw C wide literals to static_str; this breaks on platforms where wchar_t is two bytes and strings are aligned to only two byte boundaries. That's why TXR has the wli() macro. We don't want to introduce the wli() macro into linenoise, so the two choices are: duplicate the incoming mode strings into dynamic storage with string(), or pass some enum to specify file mode and locally convert to static mode string. Let's go with the latter. * linenoise.c (edit_in_editor, lino_hist_save): Use enum constant for file mode instead of mode string. * linenoise.h (enum lino_file_mode, line_file_mode_t): New enum. (struct lino_os): File opening functions use lino_file_mode_t instead of mode string. * parser.c (lino_mode_str): New static array. (lino_open, lino_open8, lino_fdopen): Take enum mode instead of string. Convert to literal through lino_mode_str table, and pass that literal to static_str.
* C++ fixes related to recent Unicode work.Kaz Kylheku2018-05-182-4/+4
| | | | | | | * lib.c (chk_wrealloc): convert needs to be a coerce. * parser.l (grammar): Use yyg instead of yyscanner; the latter is the same pointer but of void * type.
* random: reject negative bignum modulus.Kaz Kylheku2018-05-161-2/+2
| | | | | * rand.c (random): Function now rejects negative bignums, not only negative fixnums.
* linenoise: switch to wide characters, support Unicode.Kaz Kylheku2015-09-226-423/+607
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib.c (chk_wrealloc): New function. * lib.h (mem_t): Wrap with ifndef block. (MEM_T_DEFINED): New preprocessor symbol. (chk_wrealloc): Declared. * linenoise/linenoise.c (LINENOISE_MAX_DISP): Adjust to a reasonable value; just twice the number of abstract characters. The 8 factor had been chosen to cover the worst case that every character is mapped to a tab. (struct lino_state): Almost everything char typed turns to wchar_t. The TTY isn't referenced with Unix file descriptors, ifd and ofd, but abstract stream handles tty_ifs and tty_ofs. The ifs member isn't required any more since plain mode is handled via the tty_ifs stream. (mem_t): Declaration removed; now in linenoise.h. (chk_malloc, chk_realloc, chk_strdup_utf8): Declarations removed. (lino_os): New static structure. (nelem): New macro. (wcsnprintf): New static function. (enable_raw_mode, disable_raw_mode): Get Unix FD from stream using lino_os interface. (get_cursor_position, get_columns, handle_resize, record_undo, remove_noop_undo, restore_undo, undo_renumber_hist_idx, compare_completions, complete_line, lino_add_completion, next_hist_match, history_search, show_help, struct abuf, ab_append, ab_free, sync_data_to_buf, refresh_singleline, screen_rows, col_offset_in_str, refresh_multiline, scan_match_rev, scan_match_fwd, scan_fwd, find_nearest_paren, usec_delay, flash, yank_sel, delete_sel, edit_insert, edit_insert_str, edit_move_eol, edit_history_next, edit_delete, edit_backspace, edit_delete_prev_all, edit_delete_to_eol, edit_delete_line, edit_in_editor, edit, linenoise, lino_make, lino_cleanup. lino_free, free_hist, lino_hist_add, lino_hist_save, lino_set_result): Revised using streams, wide chars and lino_os interface. (lino_init): New function. * linenoise/linenoise.h (LINO_PAD_CHAR): New preprocessor symbol. (mem_t): Defined here. (MEM_T_DEFINED): New preprocessor symbol. (struct lino_os, lino_os_t): New structure. (lino_os_init): New macro. (struct lino_completions, lino_compl_cb_t, lino_atom_cb_t, lino_enter_cb_t): Switch to wchar_t. (lino_init): New function. (lino_add_completion, lino_make, linenoise, lino_hist_add, lino_hist_save, lino_hist_load, lino_set_result) * parser.c (find_matching_syms, provide_completions, provide_atom, is_balanced_line, repl): Adapt to wide character linenoise. (lino_fileno, lino_puts, lino_getch, lino_getl, lino_gets, lino_feof, lino_open, lino_open8, lino_fdopen, lino_close): New static functions. (linenoise_txr_binding): New static structure. (parse_init): Call lino_init, passing OS binding. * txr.1: Update text about the listener's limitations.
* Allow Unicode characters in identifiers.Kaz Kylheku2018-05-112-6/+59
| | | | | | | | | | * parser.l (unicode_ident): New static function. (BSCHR, NSCHR): Include UONLY match. (grammar): Use unicode_ident function to validate tokens obtained from BTOK and NTOK. * txr.1: Documented changing definition of bident and lident.
* lexer: eliminate regex alias used in one place.Kaz Kylheku2018-05-111-3/+2
| | | | | | | * parser.l (SYM, TOK): These are just aliases for the same pattern. SYM is referenced only in one place; TOK in multiple places, so let's remove SYM and replace that one reference by TOK.
* doc: fix of of.Kaz Kylheku2018-05-071-2/+2
| | | | * txr.1: Two occurrences of "of of" are corrected.
* doc: compiler sections: grammar, awkward wording.Kaz Kylheku2018-05-071-16/+16
| | | | | * txr.1: Overhaul after a proof-reading of the new LISP COMPILATION section.
* compiler: warn on misleading references in load-time.Kaz Kylheku2018-05-071-0/+9
| | | | | | | | | | | | | | | If code does something like this, we produce a warning: (let ((var 42)) (load-time (+ var 3))) A load-time form occurs in an empty lexical environment, so this code appears right but actually cannot work; the appearance is a mere trompe d'oeil. * share/txr/stdlib/compiler.tl (misleading-ref-check): New function. (compiler comp-load-time-lit): Apply misleading-ref-check.
* Version 195.txr-195Kaz Kylheku2018-05-046-122/+139
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* More reasonable fallback for self path.Kaz Kylheku2018-05-042-11/+5
| | | | | | | | | | | | | | | | * Makefile (opt/txr.o, dbg/txr.o): Set up TXR_REL_PATH preprocessor symbol on command line which specifies the hard installation path derived from the configure prefix. * txr.c (get_self_path): The fallback implementation simply returns TXR_REL_PATH. This will work if in fact the executable is installed at that path. What it means is that the build of TXR which uses this fallback get_self_path will not support relocation: the installation cannot be moved to another directory, yet still find its supporting files. This is better than what we are replacing: not working even in the original installation directory, if not invoked by an absolute path.
* bugfix: correcly obtain self path on Solaris.Kaz Kylheku2018-05-044-1/+30
| | | | | | | | | | | | * configure: Add detection for getexecname. * sysif.c (getcwd_wrap): Change static function to external. * sysif.h (getcwd_wrap): Declared. * txr.c (get_self_path): New implementation for Solaris using getexecname, which requires us to prepend the current directory name if the result is a relative path.
* Mac-OS: replace nonworking method of getting self-path.Kaz Kylheku2018-05-041-0/+13
| | | | | | | | | TXR's fall-back method of getting the executable's own path is broken in the Mac-OS port, which means that TXR doesn't work when invoked via PATH search. Mac-OS-specific code is required. * txr.c (get_self_path): New variant for Darwin, using the platform-specific function _NSGetExecutablePath.
* bugfix: interpreted destructuring doesn't do specials.Kaz Kylheku2018-05-031-8/+18
| | | | | | | | | | | | | | | It looks like I neglected to treat dynamically scoped variables in destructuring; all parameters are treated as lexical. This is only true in interpreted code; compiled destructuring treats dynamics properly because it generates a let to bind all the variables which occur, and then uses assignment to populate them. * eval.c (bind_macro_params): Instead of env_vbind, use the newly introduced lex_or_dyn_bind helper function. (op_tree_bind, op_mac_param_bind): Save and restore dyn_env around bind_macro_params and the evaluation of the associated body. In op_defmacro, this is already done.
* bind_args refactoring.Kaz Kylheku2018-05-031-77/+45
| | | | | | | | * eval.c (lex_or_dyn_bind_seq, lex_or_dyn_bind): New static functions. (bind_args): Eliminate repeated code using new helper functions. One wrong repetitions is thereby fixed also: a a neglected check of dyn_env_made.
* doc: break up long syntax.Kaz Kylheku2018-05-021-9/+14
| | | | | | | | * txr.1: The syntax synopses for the following functions and macros are too long and are awkwardly wrapped by man under 80 columns: make-time, make-time-utc, make-env, call-update-expander, call-clobber-expander and txr-if. Breaking up and shortening some identifiers.
* doc: fix recurring syntax formatting error.Kaz Kylheku2018-05-021-12/+12
| | | | | | * txr.1: I spotted a problem in the syntax synopsis of remq, remql and remqual. The same mistake was made in a few other places. remq* also had an error, though different.
