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.

/* Hey Emacs, this is -*- C -*- code! */ /* Synched up with: Not synched with FSF. */ /* Think twice before editing this file. Generated automatically by configure. The file startup.el guesses at reasonable values for load-path, exec-path, and lock-directory. This means that if you move emacs and its associated sub-tree to a different place in the filesystem, or to a different machine, you won't have to do anything for it to work. If you define the paths in this file then they will take precedence over any value generated by the heuristic in startup.el. The hardcoded paths will be checked to see if they are valid, in which case they will be used. Otherwise the editor will attempt to make its normal guess. See the NEWS file for a description of the heuristic used to locate the lisp and exec directories at startup time. If you are looking at this file because you are having trouble, then you would be much better off arranging for those heuristics to succeed than defining the paths in this file. ** Let me say that again. If you're editing this file, you're making ** a mistake. Re-read the section on installation in ../etc/NEWS. If it defines anything, this file should define some subset of the following: PATH_PROGNAME The name of the Emacs variant that's running. PATH_VERSION The version id of the Emacs variant that's running. PATH_EXEC_PREFIX The value of --exec-prefix. PATH_PREFIX The value of --prefix. PATH_LOADSEARCH The default value of `load-path'. PATH_MODULESEARCH The default value of `module-load-path'. PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-early-packages'. PATH_LATE_PACKAGE_DIRECTORIES The value of `--with-late-packages'. PATH_EARLY_PACKAGE_DIRECTORIES The value of `--with-last-packages'. PATH_PACKAGEPATH The default value of `package-path'. PATH_SITE The default location of site-specific Lisp files. PATH_SITE_MODULES The default location of site-specific modules. PATH_EXEC The default value of `exec-directory' and `exec-path'. (exec-path also contains the value of whatever is in the PATH environment variable.) PATH_DATA The default value of `data-directory'. This is where architecture-independent files are searched for. PATH_INFO This is where the info documentation is installed. PATH_INFOPATH The default value of `Info-directory-list'. These are additional places info files are searched for. */ #define PATH_PROGNAME "@PROGNAME@" #define PATH_VERSION "@version@" #ifdef EXEC_PREFIX_USER_DEFINED #define PATH_EXEC_PREFIX "@EXEC_PREFIX@" #endif #ifdef PREFIX_USER_DEFINED #define PATH_PREFIX "@PREFIX@" #endif #ifdef LISPDIR_USER_DEFINED #define PATH_LOADSEARCH "@LISPDIR@" #endif #ifdef MODULEDIR_USER_DEFINED #define PATH_MODULESEARCH "@MODULEDIR@" #endif #ifdef SITELISPDIR_USER_DEFINED #define PATH_SITE "@SITELISPDIR@" #endif #ifdef SITEMODULEDIR_USER_DEFINED #define PATH_SITE_MODULES "@SITEMODULEDIR@" #endif #ifdef EARLY_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_EARLY_PACKAGE_DIRECTORIES "@EARLY_PACKAGE_DIRECTORIES@" #endif #ifdef LATE_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_LATE_PACKAGE_DIRECTORIES "@LATE_PACKAGE_DIRECTORIES@" #endif #ifdef LAST_PACKAGE_DIRECTORIES_USER_DEFINED #define PATH_LAST_PACKAGE_DIRECTORIES "@LAST_PACKAGE_DIRECTORIES@" #endif #ifdef PACKAGE_PATH_USER_DEFINED #define PATH_PACKAGEPATH "@PACKAGE_PATH@" #endif #ifdef ARCHLIBDIR_USER_DEFINED #define PATH_EXEC "@ARCHLIBDIR@" #endif #ifdef ETCDIR_USER_DEFINED #define PATH_DATA "@ETCDIR@" #endif #ifdef DOCDIR_USER_DEFINED #define PATH_DOC "@DOCDIR@" #endif #ifdef INFODIR_USER_DEFINED #define PATH_INFO "@INFODIR@" #endif #ifdef INFOPATH_USER_DEFINED #define PATH_INFOPATH "@INFOPATH@" #endif
