(match_files): Support a stream object as a data source specification in place of a string. * parser.l (parse_reset): Update call to make_stdio_stream to take fewer arguments. * stream.c: Inclusion of <unistd.h> made properly conditional. (struct stdio_handle): pid member defined as pid_t only if we have fork functionality, otherwise defined as int. (tail_get_line, tail_get_char, tail_get_byte): New static functions. (tail_ops): New static structure. (make_stdio_stream_common): New static structure. (make_stdio_stream, make_pipe_stream): These functions lose the input and output parameters, which ended up never used. Reimplemented in terms of new common function. (make_tail_stream): New function. (make_pipevp_stream): Reimplemented in terms of new common function. (open_file, open_command): Simplified by removal of useless local variables and their computation, which used to be extra arguments to make_stdio_stream and make_pipe_stream.

(make_tail_stream, open_tail): Declared. * txr.c (txr_main): Calls to make_stdio_stream updated.
* Stream-seeking functionality.Kaz Kylheku2013-11-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bugfix in stdio_flush: check FILE * handle for null.

(strm_ops): New member, seek. (stdio_maybe_write_error): Renamed to stdio_maybe_error; takes new string argument to describe action. (stdio_put_string, stdio_put_char, stdio_put_byte): Updated call to stdio_maybe_error. (stdio_flush): Updated call to stdio_maybe_error. Check handle for null. (stdio_seek): New static function. (stdio_ops): Added stdio_seek. (pipe_ops, string_in_ops, byte_in_ops, string_out_ops, strlist_out_ops, dir_ops): Added explicit zero entries and comments for unimplemented functions. (seek_stream): New function. (stream_init): New keyword symbols interned. * stream.h (from_start_k, from_current_k, from_end_k): New variables declared. (dev_k, ino_k, mode_k, nlink_k, uid_k, gid_k, rdev_k, size_k, blksize_k, blocks_k, atime_k, mtime_k, ctime_k, s_ifmt, s_iflnk, s_ifreg, s_ifblk, s_ifdir, s_ifchr, s_ififo, s_isuid, s_isgid, s_isvtx, s_irwxu, s_irusr, s_iwusr, s_ixusr, s_irwxg, s_irgrp, s_iwgrp): Existing extern variables declared. (seek_stream): New function declared. * txr.1: Documented seek-stream.
* Fix 2013-10-06 regression in op syntax. This happens when a @varKaz Kylheku2013-10-271-1/+3
| | | | | | | | | | syntax appears in an op form, crashing the expander with infinite recursion at program load time, before the code is run. * eval.c (transform_op): The fi == var check to handle a trailing op variable in the dot position of a form needs to ensure that it really is @<num> type var, and not the @<sym> type for instance.
* Improving behavior of op and fixing a bug.Kaz Kylheku2013-10-061-5/+37
| | | | | | | | | | | | | | | | | | | | | Explicitly specifying @rest using (op ... . @rest) did not work at all. The then-func agument of iff and iffi may now be nil. * eval.c (format_op_arg): New static function. (transform_op): Handle dotted lists ending in @rest or @<num>. (supplement_op_syms): New static function. (expand_op): Add missing numeric arguments, so that all 1 through n are in the list. Trailing rest is now added under different conditions. * lib.c (do_iff): Give thenfun the same behavior on nil that elsefun enjoys. * txr.1: Updated.
* Version 67Kaz Kylheku2013-07-121-0/+1
| | | | | | | | | | | | | | * txr.c (version): Bumped. * txr.1: Bumped version, set date and documented string-cmp. * configure (txr_ver): Bumped. * eval.c (eval_init): Forgotten string-cmp registered as intrinsic. * txr.vim: Highlighting for string-cmp. * RELNOTES: Updated.
* * eval.c (eval_init): tok-str acquires new parameterKaz Kylheku2013-06-111-1/+1
| | | | | | | | * lib.c (tok_str): New parameter, keep_sep. * lib.h (tok_str): Declaration updated. * txr.1: Documentation for tok-str updated.
* * eval.c (eval_init): lazy-str's third argument is optional.Kaz Kylheku2013-06-111-5/+6
| | | | | | | | | | | | | | | | | | | Added lazy-stringp. Changing names of length-str-{gt,ge,lt,le} to be consistent with the >, >=, < and <= functions. * lib.c (lazy_stream_func): Greatly simplified implementation. The lazy list now continues by means of recursing via an optimized version of lazy_stream_cons called lazy_stream_cont. The environment structure is simplified to just hold the next item, rather than a pointless list. The pointless setting of lcons->lc.func to nil is also removed; this is always done by the caller. (lazy_stream_cont): New static function, similar to lazy_stream_cons, but optimized by not consing up a new function and new environment cell. (lazy_stream_cons): The environment for the update function is simplified to just a single cons. * txr.1: Documented lazy string functions and lazy-stream-cons.

| | | | | | | | | | arguments to plus, so that the from object is on the left. This change was introduced in a commit on 2012-02-14, causing character ranges to break due to bug that addition did not commute for char + fixnum. Although the previous commit fixed the regression, it's still good to have the object on the left in case there are some future data types in case there is ever some form of addition which does not commute.

Using the value properly is going to be the caller's responsibility. (push): push may be a mutation, so use set. (intern): Uset set to mutate a hash entry. (acons_new_l, aconsq_new_l): Use set when replacing *list. * lib.h (PTR_BIT): New preprocessor symbol. (obj_common): New macro for defining common object fields. type_t is split into two bitfields, half a pointer wide, allowing for generation to be represented.
