@@ -1,3 +1,56 @@ + TXR 77 + 2014-01-30 + + + Features + + - More streamlined parser containing fewer hacks, and fewer obscure + cases that don't work. + + - @'expr syntax now works as expected in directives for evaluating quoted + TXR Lisp expressions. + + - In nested uses of the do and op operators in TXR Lisp there is now + a way to refer to the outer parameters from the inner nestings, using + compounded meta syntax like (op (op @1 @@1)), where @1 is argument 1 + of the function denoted by the inner op, and @@1 is argument 1 of the + outer function. Each additional @ "escapes" out one level of nesting + of the op syntax. + + - New update and hash-update functions. + + - The interfaces of reduce-left and reduce-right functions has been + improved, making them easier to use, while mostly retaining backward + compatibility. + + - New functions remove-path and rename-path for removing and renaming + filesystem objects. + + - Catenated streams, previously an internal feature, are exposed + now via the make-catenated-stream function. + + - Scope rule change for expressions that provide default intialization + for optional arguments. These eexpressions now have the parameters + in scope, and so now uses like (lambda (x : (y (length x))) ...) + are possible where y is initialized with (length x) if the argument + is not supplied. Previously, parameter x would not have been considered + to be in scope of the expression (length x). + + + + Bugs + + - Fixed neglected handling of result form in dohash syntax. + + - In the object printer, the handling of syntax like @(sys:var x ...) was + ignoring any additional ... forms, and rendering as @x. + + - Fixed possible race condition in tail streams, whereby when a file + rotates, the stream prematurely follows the new file, neglecting + to read the last piece of material just added to the previous file. + + + TXR 76 2014-01-23 |
