* Centered fields in format.Kaz Kylheku2015-07-281-6/+13
| | | | | | | | | | | | * stream.c (enum align): New enum. (vformat_align_pre, vformat_align_post): New static functions. (vformat_num, vformat_str): Argument left renamed to align, and changed to enum align. vformat_align_pre and vformat_align_post are called to generate the correct padding for left, center and right alignment. (vformat): Two-valued local variable left turned into three-valued align. The ^ prefix on the width field is recognized. * txr.1: Documented ^ width prefix.

* * parser.l (grammar): Do not allow unescaped newline inKaz Kylheku2015-07-231-6/+21
| | | | | | | | | | | word list literals and word list quasiliterals, except in <= 109 compatibility mode. An escaped newline in these literals, together with surrounding whitespace, now produces a single space, except in <= 109 compatibility mode. * txr.1: Documented new rules for WLL's and QLL's, and added compatibility notes.

(seventh, eighth, ninth, tenth): New functions. * lib.h (seventh, eighth, ninth, tenth): Declared. * share/txr/stdlib/place.tl: place macros defined for second through tenth. * txr.1: Documented.
* * lisplib.c (place_set_entries): Add *place-macro* andKaz Kylheku2015-07-221-3/+44
| | | | | | | | | | | | | | define-place-macro to list of names. * share/txr/stdlib/place.tl (*place-macro*): New global hash. (sys:tigger-load, sys:pl-expand): New functions. (call-update-expander, call-clobber-expander, call-delete-expander): Recognize and expand place macros. (define-place-macro): New macro.

| | | | | | | | * share/txr/stdlib/place.tl (placelet*): New macro. * lisplib.c (place_set_entries): Add placelet* to list of names. * txr.1: Updated to document placelet* and fix mistakes.
* * eval.c (eval_init): Register bindable as intrinsic.Kaz Kylheku2015-07-101-0/+20

* New placelet macro.Kaz Kylheku2015-07-101-0/+83
| | | | | | | | | | | | | | * lisplib.c (place_set_entries): Add placelet to list of names. * share/txr/stdlib/place.tl (sys:placelet1, placelet): New macros. (defplace dwim): Do not retrieve the place's value into a local variable and have the getter expand to that variable. Rather, have the getter retrieve the value. A getter that refers to a cached copy breaks the semantics of placelet, and any place operator which can evaluate the location after it is stored. * txr.1: Documented placelet.
* * txr.1: Replace callf example under mapf.Kaz Kylheku2015-07-061-3/+2

* Clarify clear-error and flush return value.Kaz Kylheku2015-07-061-1/+5
| | | | | | | | | | | * stream.c (stdio_clear_error): Return the prior value of h->err. Do not inspect feof(h->f) or ferror(h->f); just clear the error status of the stream. (stdio_close): Set h->err from errno if fclose failed. (dir_clear_error): Return prior value of h->err. * txr.1: Document return value convetion for clear-error, and flush-stream.

* Support trailing semicolon after hex/octal characters.Kaz Kylheku2015-07-021-1/+16
| | | | | | | | | | | | | | | | * parser.l (%option): Remove nounput option since we need yyunput. (grammar): Rule for matching hex and octal escape in SPECIAL state recognizes optional semicolon. In 109 compatibility, this is pushed back into the stream, otherwise consumed. * txr.1: Updated documentation, including compat notes. * genvim.txr (txr_char): Include optional semicolon in match. Corrected some errors where 8 and 9 were being included as matches for octal digits. (txr_error): Default match for \x or \o not followed by digits.

* Third round of quasiliteral-related fixes.Kaz Kylheku2015-06-261-5/+10
| | | | | | | | | * parser.l (char_esc): Recognize \@ escape. (grammar): Add a rule for a \@ escape in quasiliterals, and quasi word list literals. * txr.1: Document \@, and remove the lie that @@ encodes for a single @ in quasiliterals.
