* New place-mutating operators.Kaz Kylheku2016-09-081-0/+43
| | | | | | | * share/txr/stdlib/place.tl (pinc, pdec, test-set, test-clear, compare-swap, test-inc, test-dec): New macros. * txr.1: Documented.
* No-op expansion for (inc 0) and (dec 0).Kaz Kylheku2016-09-081-2/+2
| | | | | | | * share/txr/stdlib/place.tl (inc, dec): If the delta is zero, don't generate code which calls getter and setter; just generate the place form as the output.
* Awk comes to TXR via a macro.Kaz Kylheku2016-09-071-0/+148
| | | | | | | | | * lisplib.c (awk_set_entries, awk_instantiate): New static functions. (lisplib_init): Register auto-loading for awk module via new functions. * share/txr/stdlib/awk.tl: New file.
* New rslot macro to suport upcoming awk macro.Kaz Kylheku2016-09-071-0/+27
| | | | | | | | | | | | This provides a way to create lexical macros denoting slots, such that method are invoked when they are updated. * lisplib.c (struct_set_entries): Add rslot to list of auto-load symbols for struct.tl module. * share/txr/stdlib/struct.tl (sys:rslotset): New function. (rslot, rslot): New macro and place macro. (sys:rslot): New place kind.
* Bugfix: issue with expansion of place macros.Kaz Kylheku2016-09-071-1/+1
| | | | | | | | | | | | | | | | | | | The expansion of a place macro form should not be subject to a complete macro-expansion (as a regular macro form). Only one round of expansion should be performed, and the results should be re-tried as a place macro. Otherwise an opportunity to expland a place macro will be missed. * share/txr/stdlib/place.tl (sys:pl-expand): Use macroexpand-1 rather than macroexpand. * txr.1: Documentation updated to make the new behavior clear. It's unlikely that anything in the world depends on this, so no backward compatibility switch is being provded to the old behavior. In situations where this makes a difference, the old behavior is likely too wrong to be useful.
* Bugfix: x not macro-expanded in (set [x i] y).Kaz Kylheku2016-09-071-10/+13
| | | | | | | | | * share/txr/stdlib/place.tl (sys:l1-setq): Expand sym, because it might not be a symbol. If it isn't a symbol, just generate a set. (dwim): Unconditionally bind sys:*lisp1* to t, whether or not the unexpanded place is a symbol. It could expand to a symbol. The context is lisp-1 if it does that.
* Bugfix: nthcdr place not obtaining macro env.Kaz Kylheku2016-09-071-5/+9
| | | | | | | | | | | | * share/txr/stdlib/place.tl (sys:*pl-env*): New special variable for passing macro-expansion environment to expanders. (call-update-expander, call-clobber-expander, call-delete-expander): bind sys:*pl-env* with passed-in env argument, so if the expander needs to itself recursively expand a macro, it has the macro-time env. (nthcdr): Do not try to capture :env parameter, because this will always be nil. Refer to sys:*pl-env* instead.

* Somew new path access testing functions.Kaz Kylheku2016-05-041-3/+26
| | | | | | | | | | | | | | * lisplib.c (path_test_set_entries): New elements in the list for path-readable-to-me-p, path-read-writable-to-me-p, and path-strictly-private-to-me-p. * share/txr/stdlib/path-test.pl (sys:path-access): Test bitwise combinations of permissions, so read+write can be tested in one call. (path-readable-to-me-p, path-read-writable-to-me-p, path-strictly-private-to-me-p): New functions. * txr.1: Documented.

| | | | | | | | * share/txr/stdlib/path-test.tl (sys:path-access): Comment added to note use restriction to identical permissions for all three scopes. Fixed incorrect use of logior instead of logand which causes strict permission test to be applied to user even when testing for non-execute permisisons.
* Version 139.txr-139Kaz Kylheku2016-04-221-1/+1
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* Optimization in path-private-to-me-p.Kaz Kylheku2016-04-221-8/+8
| | | | | | | | | * share/txr/stdlib/path-test.tl (path-private-to-me-p): Use mlet to initialize the g variable lazily, so that getgrgid is only called when g is used. getgrid is a fairly heavy-weight function, and it's only used to resolve the case when a file is writable to the group owner (is the user the only member of that group?)
* Put notes into cadr sources that they are generated.Kaz Kylheku2016-04-161-0/+2
| | | | | | * gencadr.txr: Insert notice about generation. * cadr.c, cadr.h, share/txr/stdlib/cadr.tl: Regenerated.

| | | | | | | | | | * lisplib.c (yield_set_entries): Add obtain* and obtain*-block to autoload list. * share/txr/stdlib/yield.tl (obtain*, obtain*-block): New macros. * txr.1: Documented.
* Don't expand replacements of symbol macros.Kaz Kylheku2016-04-121-2/+2
| | | | | | | | | * eval.c (expand_symacrolet, do_expand): Don't expand the replacement form of a global or lexical symbol macro at the time it is bound to its symbol. This is almost certainly wrong in situations where it makes a difference. * txr.1: Noted in compatibility section.
* Fix throw used instead of throwf in defstruct.Kaz Kylheku2016-04-061-9/+9
| | | | | | * share/txr/stdlib/struct.tl (defstruct): Errors about duplicate :init, :postinit or :fini were incorrectly thrown using throw rather than throwf.
* Diagnose bad supertype in defstruct.Kaz Kylheku2016-04-061-1/+6
| | | | | | | * share/txr/stdlib/struct.tl (defstruct): If super isn't nil, it must name an existing struct type, or an exception is thrown. Previously, a nonexistent struct was silently treated as if nil had been specified.
* Define a sock-peer syntactic place.Kaz Kylheku2016-03-311-0/+6
| | | | | | | * share/txr/stdlib/socket.tl (sock-peer): Syntactic place defined, allowing (set (sock-peer sock) addr). * txr.1: Documented sock-peer as accessor and sock-set-peer.
* Version 137.txr-137Kaz Kylheku2016-03-301-1/+1

| | | | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated. * inst.nsi: include .tl files in installer
* Prefix override in IP prefix functions.Kaz Kylheku2016-03-011-12/+13
| | | | | | | | | | | * share/txr/stdlib/socket.tl (sys:str-inaddr-net-impl): New argument weff. Overrides prefix. Bugfix here: we must base the number of octets on the calculated width before wextra is added to it. (str-inaddr-net, str-inaddr6-net): New optional width argument. * txr.1: Documented.
* Fix triple-colon in ipv6 text representation.Kaz Kylheku2016-03-011-18/+17
| | | | | | | | | * share/txr/stdlib/socket.tl (sys:in6addr-condensed-text): New function containing common code. Uses window-mappend to selectively convert a compressed range of zeros to either colon or empty string based on whether it is in the middle or end. (str-in6addr, str-in6addr-net): Use new function.
* Functions for address prefixes to slash notation.Kaz Kylheku2016-02-291-0/+60
| | | | | | | | | | | * lisplib.c (sock_set_entries): Autload entries for str-inaddr-net and str-in6addr-net. * share/txr/stdlib/socket.tl (str-inaddr-net, str-in6addr-net): New functions. * txr.1: Documented str-inaddr, str-in6-addr, str-inaddr-net and str-in6addr-net.
* IP address to string functions.Kaz Kylheku2016-02-291-0/+38
| | | | | | | | * lisplib.c (sock_set_entries): Add str-inaddr and str-in6addr to list of autoload identifiers. * share/txr/stdlib/socket.tl (str-inaddr, str-in6addr): New functions.
* Adding socket support: unix, ipv4, ipv6.Kaz Kylheku2016-02-261-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * socket.c, socket.h: New files. * Makefile: include new socket.o among objects if have_objects variable is defined to 'y'. * configure (have_sockets): New variable. New configure test for socket-related functionality. (HAVE_SOCKETS, HAVE_GETADDRINFO): New configuration preprocessor symbols. Also, reordering the shell probing so that /usr/xpg4/bin/sh is the last fallback. On Solaris, it chokes on some code that is needed for Solaris. * lisplib.c (sock_set_entries, sock_instantiate): New static functions. (lisplib_init): Register new functions as autoload hooks. * share/txr/stdlib/socket.tl: New file. * stream.c (socket_error_s): New symbol variable. (struct stdio_handle): New members, family and type, helping stdio streams represent sockets too. (stdio_stream_mark): Mark new members of struct stdio_handle. (make_stdio_stream_common): Initialize new members. (make_sock_stream, stream_fd, sock_family, sock_type, open_socket, open_sockfd): New functions. (stream_init): Initialize socket_error_s variable.

* defstruct: order function slots before other static slots.Kaz Kylheku2016-01-031-15/+17
| | | | | | | | | | | | | | | | | This allows the initializer expressions for static slots to instantiate objects, and those instances can rely on methods being set up. * share/txr/stdlib/struct.tl (sys:prune-nil-inits): Recognize :function keyword as denoting a static slot. (defstruct): Represent methods and functions as (:function ...) items rather than (:static ...) so they can be distinguished. Function slots appear before other static slots in the static slot list, and their initializing code is placed into the the static-initfun lambda of the sys:make-struct-type call in this order. * txr.1: Documented.
* Better bad slot syntax diagnostic in defstruct.Kaz Kylheku2016-01-031-1/+4
| | | | | | * share/txr/stdlib/struct.tl (defstruct): Issue different error message for a slot specifier which isn't a symbol, and wasn't recognized as a special syntax.

| | | | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. Bumped copyright year in configure. (Could be last chance this year). * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* New condlet macro; small change to iflet/whenlet.Kaz Kylheku2015-12-181-5/+12
| | | | | | | | | | | | | | | | | | | | | | | * eval.c (me_iflet_whenlet): Allow the test form to be an atomic expression instead of bindings. This allows iflet to be used as the sole target construct of condlet, while allowing condlet to have a fallback clause with t. It also means that an empty list of bindings is allowed (since it is the atom nil). * lisplib.c (ifa_set_entries): Add "condlet" to the autoload names for the ifa module. That's where we are adding condlet. * share/txr/stdlib/ifa.tl (sys:if-to-cond): New macro expander helper function, generalizing the writing cond-like macros based on if-like operators. (conda): Rewritten using sys:if-to-cond. (condlet): New macro. * txr.1: Documented change in iflet/whenlet. Documented condlet.
