	the line read based on whether the source itself is interactive,
	return it based on whether the line itself should be treated as

Wed Nov 29 19:35:44 WST 2006 John Darrington <john@darrington.wattle.id.au>

Tue Oct 31 19:28:19 2006  Ben Pfaff  <blp@gnu.org>

	* str.h: [!HAVE_STRCHR] Drop compatibility code, because now we
	assume a C89 compliant library.  (Gnulib makes this assumption so
	we might as well too.)

	rehashing.
	
	* hash.c: (locate_empty_entry) New function.
	(rehash) Use locate_empty_entry() instead of

	* message.c message.h: Added functions to create and copy a msg.

Tue May  2 15:41:50 2006  Ben Pfaff  <blp@gnu.org>

	* str.c (ds_append_uninit): No need to add 1 to arg passed to
	ds_extend(), because the argument does not include space for a
	null terminator.  Also, fix warning.

Tue Apr 25 11:07:19 2006  Ben Pfaff  <blp@gnu.org>

	Finish reforming error message support.  In this phase, move
	message.c into libpspp.
	
	* message.c: Move here from src/.  Also remove a few unneeded
	headers.

	* automake.mk (src_libpspp_libpspp_a_SOURCES): Add message.c. 

Tue Apr 25 10:54:44 2006  Ben Pfaff  <blp@gnu.org>

	Continue reforming error message support.  In this phase, drop
	actual message printing from core code, substituting a callback,
	and add the callback to each UI.  Also, move verbose_msg() into
	its own module.

	* automake.mk (src_libpspp_libpspp_a_SOURCES): Added
	verbose-msg.c, verbose-msg.h.

	* verbose-msg.c: New file.

	* verbose-msg.h: New file.

Mon Apr 24 17:26:47 2006  Ben Pfaff  <blp@gnu.org>

	Continue reforming error message support.  In this phase, rename
	all the message functions and types to start with "msg", except
	for the ones that will be moving to other modules anyway.

	All references to the identifiers below were updated likewise.
	
	* message.h: (enum file_locator) Renamed `enum msg_locator'.
	(struct error) Renamed `struct msg'.
	(err_assert_fail) Renamed msg_assert_fail().

Sun Apr 23 22:07:06 2006  Ben Pfaff  <blp@gnu.org>

	Continue reforming error message support.  In this phase, get rid
	of message "titles" and put the message text in `struct error'.
	Now `struct error' encapsulates a message more properly.
	
	* message.h: (struct error) Remove `title' member.  Add `text'
	member.
	
Sun Apr 16 20:43:35 2006  Ben Pfaff  <blp@gnu.org>

	Continue reforming error message support.  In this phase, we
	divide the classification of messages along "category" and
	"severity" axes.

	* message.h: (enum msg_class) Named this set of enumerations.
	(enum msg_category) New enum: MSG_GENERAL, MSG_SYNTAX, MSG_DATA.
	(enum msg_severity) New enum: MSG_ERROR, MSG_WARNING, MSG_NOTE.
	(msg_class_to_category) New inline function.
	(msg_class_to_severity) New inline function.
	(msg_class_from_category_and_severity) New inline function.
	(struct error) Removed `class' member, added `category',
	`severity'.  Updated all users of this struct to use the new
	members.

Sun Apr 16 20:33:19 2006  Ben Pfaff  <blp@gnu.org>

	* str.c (ds_vprintf): Don't try to write into the string if it is
	null.

Sun Apr 16 18:52:41 2006  Ben Pfaff  <blp@gnu.org>

	GNU standards require "file name" instead of "filename" in
	documentation.  It's nice for our code to follow the convention
	too.
	
	* message.h: (struct file_locator) Rename filename member to
	file_name.  Updated all references.

Sun Apr 16 16:05:43 2006  Ben Pfaff  <blp@gnu.org>

	Continue reforming error message support.  In this phase, we get
	rid of VM() and the other msg() support for "verbosity", replacing
	it by a new function verbose_msg().

	* message.h: (enum ERR_CLASS_COUNT) Renamed ERR_CLASS_CNT.
	(enum ERR_CLASS_MASK) Removed.
	(enum ERR_VERBOSITY_SHIFT) Removed.
	(enum ERR_VERBOSITY_MASK) Removed.
	(macro VM) Removed.

Sun Apr 16 11:48:07 2006  Ben Pfaff  <blp@gnu.org>

	Start reforming error message support.  In this phase, we get rid
	of "installation errors" and change all uses of msg() in the
	output drivers to uses of error() or error_at_line().

	* message.h: Remove IE, IS enums.

Mon Apr  3 11:10:21 2006  Ben Pfaff  <blp@gnu.org>

	* str.c: (ds_separate) Change interface for cleanliness and
	consistency with ds_tokenize(), and rewrite to shorten and
	simplify.  Updated all callers.
	(ds_tokenize) New function.

Fri Mar 31 10:38:46 2006  Ben Pfaff  <blp@gnu.org>

	Add freaderror() analogous to fwriteerror() in gnulib.

	* freaderror.c: New file.

	* freaderror.h: New file.

	* str.c: (ds_create) Adjust capacity selection.
	(ds_init) Use MAX macro for clarity.
	(ds_create_substr) Rewrote.
	(ds_replace) Renamed ds_assign_c_str(), reimplemented.  Changed
	all callers to use a ds_assign_*() function.
	(ds_init_substring) New function.
	(ds_assign_string) New function.
	(ds_assign_substring) New function.
	(ds_assign_buffer) New function.
	(ds_assign_c_str) New function.

	(ds_trim_spaces) New function.
	(ds_separate) New function.
	(ds_c_str) Make tolerant of null pointer, allowing static
	initialization of strings.
	(ds_find) Rename ds_span(), change interface.
	(ds_n_find) Rename ds_cspan(), change interface.
	(ds_at) New function.
	(ds_first) Reimplement in terms of ds_at().
	(remove_comment) New function.
	(ds_get_config_line) Reimplement in terms of other functions.
	Change type of LINE_NUMBER parameter.  Updated all callers.
	(ds_vprintf) Modify for clarity.
	(ds_putc) Better to be safe than sorry.
	(ds_putc_multiple) New function.

	* str.h: (struct string) Reorder members.
	(macro DS_INITIALIZER) New macro that can be used to initialize a
	string (as empty).
	(ds_c_str) Remove inline version.

Tue Mar 28 13:49:11 WST 2006 John Darrington <john@darrington.wattle.id.au>

	* str.[ch]: New functions ds_create_substr, ds_find, ds_n_find, 
	ds_ltrim_spaces

Sat Mar  4 11:55:16 2006  Ben Pfaff  <blp@gnu.org>

	* str.h: Now assume that sprintf() returns the correct value.
	Always implement spprintf as a static inline function.  Change
	nsprintf, nvsprintf to simple macros that call sprintf, vsprintf.

	definitions.

Thu Mar  2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
	
	* Moved files from src directory
