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.
