Some streams now + support ungetting a byte or character, which was a glaring omission + in the API, without which some common scanning tasks are awkward. + + - TXR Lisp functions with optional parameters can now specify expressions + to give those arguments values when the arguments are missing. + + - New operators in TXR Lisp: append-each and append-each*. + + - Change in the Lisp structure printer. The special structure generated by + the read syntax @sym and @(...) now prints back in the same syntax, + rather than as (sys:var sym) and (sys:expr ...). + + Bugs + + - Fix in put-byte function: before invoking the underlying operation, + it was testing whether the put-char operation exists for the stream, + rather than the put-byte operation. This would result in a crash if + the stream supports put-char but not put-byte. + + - Mistake in calculating bitmasks for regex character class ranges, + resulting in incorrect behavior for ranges whose upper range is + a character code corresponding to the last bit of a word in the + bitmask array, e.g. [A-\x7f], resulting in failures to match + 32 or more characters in the upper end of the range. + + - Missing documentation filled in for the functions throw, throwf and error. + + + TXR 74 2014-01-13 |
