In some cases, these + reduce an expression which contains exotic operators such that it + can be compiled to NFA. + + - Structures: + - Structures can now have static slots: slots shared among all instances + of the same type (but not other types, not even derived types). + - Static slots are now the preferred the basis for implementing functions + and methods. + - The defstruct syntax has a richer syntax which lets static slots + be expressed, as well as methods. + - Construction and finalization code can be specified in defstruct. + - Many new functions related to structures. + + - Optimization in lazy strings: forcing lazy strings is more efficient. + + - String input streams do not force lazy strings now. + + - The "matches nothing" regular expression represented in the + abstract syntax by the object t now handled by regex printer, + and rendered as []. + + Bugs: + + - Fixed a silly delete-previous-word behavior in multi-line mode: + not treating the line-break as a whitespace character that separates words. + + - Fixed various problems in screen update and cursor positioning behavior in + interactive listener, affecting multi-line mode. + + - Fixed two bugs in the ifa/conda macros. + + - The return and return-from operators do not abort TXR when a label is not + found, but properly throw an exception. + + - Garbage collection: if GC is triggered in response to a malloc + delta, a full GC is now performed. This prevents runaway memory + allocation behavior in code which manipulates large arrays, strings + or integers. + + - Fixed strangely compounded error message issued in the situation that + unbound variables occur in the TXR pattern language. + + - Various "internal error" situations in the regex module now throw + exceptions. Consequently, TXR will not die if a bad abstract syntax + tree is passed to the regex compiler. + + - Regex printer was throwing an exception when printing a character + class containing \w, \s or \d. + + + TXR 117 2015-09-23 |
