* src/bignum.c (make_neg_biguint): New function. * src/lread.c (read1): Do not mishandle an unquoted symbol with name equal to something like "1\0x", i.e., a string of numeric form followed by a NUL byte. Formerly these symbols were misread as numbers. (string_to_number): Change last argument from an integer flag to a pointer to the length. This lets the caller figure out how much of the prefix was used. All callers changed. Add a fast path if the integer (sans sign) fits in uintmax_t. Update comments and simplify now that bignums are present. * src/print.c (print_object): Fix quoting of symbols that look like numbers, by relying on string_to_number for the tricky cases rather than trying to redo its logic, incorrectly. For example, (read (prin1-to-string '\1e+NaN)) formerly returned "1e+NaN", which was wrong: a backslash is needed in the output to prevent it from being read as a NaN. Escape NO_BREAK_SPACE too, since lread.c treats it like SPACE. * test/src/print-tests.el (print-read-roundtrip): Add tests illustrating the abovementioned bugs. |
