@@ -1,3 +1,55 @@ + TXR 84 + 2014-03-07 + + + Features + + - TXR Lisp no longer uses one quote for regular quote and quasiquote syntax. + The quasiquote character is now ^ and the apostrophe is just regular quote. + This change breaks backward compatibility, unfortunately, but the + single-quote experiment had to come to an end, now that TXR has a powerful + macro facility, with quasiquotes playing a central role. + + - TXR Lisp exposes the environment manipulation functions make-env, env-vbind + and env-fbind. + + - New function log10 for base 10 logarithms. + + - New functions open-files and open-files* for opening a big catenated stream + which marches through multiple files as if they were one. + + - New directive, @(assert), for writing certain kind of robust matching code + more simply. + + - put-line can be called with no arguments, in which case it just writes + a newline to standard output. + + - In the format function, if a precision is specified as *, it can now + have a leading 0 in front of it, which applies as usual (to the formatting + of an integer which falls short of the number of digits required + by the precision). + + Bugs + + - In the format function, the * character for specifying a variable + field width or precision (derived from an integer argument) was broken. + + - Fixed a regression causing the exception "t is not a cons" on queries + that match data, when no input files are specified. + + - Fixed a regression causing file names not to be tracked in the pattern + matching language, and consequently error messages not to give that + useful information. + + - Fixed some bugs related to command line processing, which had recently + been rewritten: the element nil was being added to *args* in some situations, + the argument - would end up repeated twice, and args was being sometimes + manipulated in such a way that (ldiff *full-args* *args*) wouldn't work, + due to new conses pushed onto *args* so that it's not a structural + suffix of *full-args*. + + + TXR 83 2014-03-02 |
