Attempts to redefine the relationship + between two types if they are already connected by one; + this covers circularity and other cases, while still allowing + a relaxed order of definition. + +2009-10-17 Kaz Kylheku <kkylheku@gmail.com> + + * gc.c (mark_obj_tail): New macro. + (mark_obj): Optimized with manual tail recursion. + The funtion will no longer generate long call stacks + for long lists. Descending to the car field of + a cons is still recursive, but ``car-heavy'' + trees are rare. + +2009-10-16 Kaz Kylheku <kkylheku@gmail.com> + + Resurrect -f option, with different meaning. + We need "-f query-file" so that hash-bang scripts + can be written which can pass options to txr. + + * txr.c (help, main): Inplement and document -f. + Also bugfix: do not throw file open errors as exceptions + of type error, because these cause an abort, potentially leading to a + core dump. They are now thrown as file_error. + * txr.1: Documented -f. + +2009-10-16 Kaz Kylheku <kkylheku@gmail.com> + + Implemented @(next arg) for treating the command line + as an input source. + + * txr.1: Updated, and fixed a few unrelated mistakes. + * lib.c (dir): Removed unused symbol globa. + (args): New symbol global. + * lib.h (dir): Declaration removed. + (args): Declared. + match.c (match_files): Implemented @(next arg). + Had to hack laziness to the file opening logic in match_files. + If the function is entered with a spec whose first + directive is @(next), then it defers opening the first + file in the list of files (since it will be immediately + abandoned in favor of another input source). + This prevents an error in the situation when the + arguments do not name files, and there is a @(next args) + directive to process them as an input source. + 2009-10-16 Kaz Kylheku <kkylheku@gmail.com> Version 016 |
