Use parse_integer() in read_atom(); support bases with ratios like integers src/ChangeLog addition: 2015-05-08 Aidan Kehoe <kehoea@parhasard.net> * data.c (init_errors_once_early): Move the Qunsupported_type here from numbers.c, so it's available when the majority of our types are not supported. * general-slots.h: Add it here, too. * number.c: Remove the definition of Qunsupported_type from here. * lread.c (read_atom): Check if the first character could reflect a rational, if so, call parse_integer(), don't check the syntax of the other characters. This allows us to accept the non-ASCII digit characters too. If that worked partially, but not completely, and the next char is a slash, try to parse as a ratio. If that fails, try isfloat_string(), but only if the first character could plausibly be part of a float. Otherwise, treat as a symbol. * lread.c (read_rational): Rename from read_integer. Handle ratios with the same radix specification as was used for integers. * lread.c (read1): Rename read_integer in this function. Support the Common Lisp #NNNrMMM syntax for parsing a number MMM of arbitrary radix NNN. man/ChangeLog addition: 2015-05-08 Aidan Kehoe <kehoea@parhasard.net> * lispref/numbers.texi (Numbers): Describe the newly-supported arbitrary-base syntax for rationals (integers and ratios). Describe that ratios can take the same base specification as integers, something also new. tests/ChangeLog addition: 2015-05-08 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-reader-tests.el: Check the arbitrary-base integer reader syntax support, just added. Check the reader base support for ratios, just added. Check the non-ASCII-digit support in the reader, just added.
