* Changes to the distribution
+** New module (ice-9 stack-catch):
+
+stack-catch is like catch, but saves the current state of the stack in
+the the-last-stack fluid for the debugger to inspect or in able to
+re-throw an error.
+
** The module (ice-9 and-let*) has been renamed to (ice-9 and-let-star)
This has been done to prevent problems on lesser operating systems
See ice-9/match.scm for brief description or
http://www.star-lab.com/wright/code.html for complete documentation.
+This module requires SLIB to be installed and available from Guile.
+
* Changes to the stand-alone interpreter
+** Evaluation of "()", the empty list, is now an error.
+
+Previously, you could for example write (cons 1 ()); now you need to
+be more explicit and write (cons 1 '()).
+
** It's now possible to create modules with controlled environments
Example:
* return 0 if the request is for 0 bytes, with no end-of-file
check
+** New function: object->string OBJ
+
+Return a Scheme string obtained by printing a given object.
+
** New function: port? X
Returns a boolean indicating whether X is a port. Equivalent to
closed even if a port is using it. The return value is
unspecified.
+** New function: crypt password salt
+
+Encrypts `password' using the standard unix password encryption
+algorithm.
+
+** New function: chroot path
+
+Change the root directory of the running process to `path'.
+
+** New functions: getlogin, cuserid
+
+Return the login name or the user name of the current effective user
+id, respectively.
+
+** New functions: getpriority which who, setpriority which who prio
+
+Get or set the priority of the running process.
+
+** New function: getpass prompt
+
+Read a password from the terminal, first displaying `prompt' and
+disabling echoing.
+
+** New function: flock file operation
+
+Set/remove an advisory shared or exclusive lock on `file'.
+
+** New functions: sethostname name, gethostname
+
+Set or get the hostname of the machine the current process is running
+on.
+
+** New function: open-input-string string
+
+Return an input string port which delivers the characters from
+`string'. This procedure, together with `open-input-string' and
+`get-output-string' implements SRFI-6.
+
+** New function: open-output-string
+
+Return an output string port which collects all data written to it.
+The data can then be retrieved by `get-output-string'.
+
+** New function: get-output-string
+
+Return the contents of an output string port.
+
** Deprecated: close-all-ports-except. This was intended for closing
ports in a child process after a fork, but it has the undesirable side
effect of flushing buffers. port-for-each is more flexible.
** Removed constants: bignum-radix, scm-line-incrementors
+** define-method: New syntax mandatory.
+
+The new method syntax is now mandatory:
+
+(define-method (NAME ARG-SPEC ...) BODY ...)
+(define-method (NAME ARG-SPEC ... . REST-ARG) BODY ...)
+
+ ARG-SPEC ::= ARG-NAME | (ARG-NAME TYPE)
+ REST-ARG ::= ARG-NAME
+
+If you have old code using the old syntax, import
+(oop goops old-define-method) before (oop goops) as in:
+
+ (use-modules (oop goops old-define-method) (oop goops))
+
* Changes to the gh_ interface
* Changes to the scm_ interface
+** New function: scm_c_read (SCM port, void *buffer, scm_sizet size)
+
+Used by an application to read arbitrary number of bytes from a port.
+Same semantics as libc read, except that scm_c_read only returns less
+than SIZE bytes if at end-of-file.
+
+Warning: Doesn't update port line and column counts!
+
+** New function: scm_c_write (SCM port, const void *ptr, scm_sizet size)
+
+Used by an application to write arbitrary number of bytes to an SCM
+port. Similar semantics as libc write. However, unlike libc
+write, scm_c_write writes the requested number of bytes and has no
+return value.
+
+Warning: Doesn't update port line and column counts!
+
** New function: scm_init_guile ()
In contrast to scm_boot_guile, scm_init_guile will return normally
SCM_ROSTRINGP, SCM_RWSTRINGP, SCM_VALIDATE_RWSTRING, SCM_ROCHARS,
SCM_ROUCHARS, SCM_SETLENGTH, SCM_SETCHARS, SCM_LENGTH_MAX, SCM_GC8MARKP,
SCM_SETGC8MARK, SCM_CLRGC8MARK, SCM_GCTYP16, SCM_GCCDR, SCM_SUBR_DOC,
-SCM_OPDIRP, SCM_VALIDATE_OPDIR
+SCM_OPDIRP, SCM_VALIDATE_OPDIR, SCM_WTA, RETURN_SCM_WTA
Use SCM_ASSERT_RANGE or SCM_VALIDATE_XXX_RANGE instead of SCM_OUTOFRANGE.
Use scm_memory_error instead of SCM_NALLOC.
Use SCM_TYP16 instead of SCM_GCTYP16.
Use SCM_CDR instead of SCM_GCCDR.
Use SCM_DIR_OPEN_P instead of SCM_OPDIRP.
+Use SCM_MISC_ERROR or SCM_WRONG_TYPE_ARG instead of SCM_WTA.
+Use SCM_MISC_ERROR or SCM_WRONG_TYPE_ARG instead of RETURN_SCM_WTA.
** Removed function: scm_struct_init
This can be used to set an apply function to a smob type.
+** Deprecated function: scm_strprint_obj
+
+Use scm_object_to_string instead.
