[XGP-announce] XGP 0.2.1

[Lindsey S. <sp...@al...>]

XGP 0.2.1 is now available at
http://xgp.sourceforge.net/

 From release 0.2.0 to 0.2.1:

	* Added various MacProlog32-compatible predicates in the following
	categories:
		-	files (including load_files/[1,2], optimize_files/1,
			source_file/[1, 2], source_load/1, files/2, folders/[1, 2],
			ftype/3, exists_file/1, resolve_alias_and_link/2,
			resolve_alias/2, absolute_file_name/3).
		-	persistent values (global variable, prolog state,
			and gensym).
		-	miscellaneous (including sort/3, forall/2, record_qpic/3,
			charof/2, lower/2, upper/2, pname/2, writeqnl/1,
			writeqseqnl/1, writeq_list/[1, 2],and concat/2).

	* Fixed bugs in:
		- 	cw_get_item/3 to handle the Value correctly when it's
			not an atom.
		- 	support for gprolog reading from an XGP document.
		- 	<~ / 2 and ~> / 2 when the target is a stream (checking
			the current_alias complained that it wasn't an atom).
		-	so that XGP won't "hang". For instance, consulting a
			document while at a trace prompt or waiting on a button
			click would cause XGP to hang and now does not.

	* Various changes to support UTF8 encoding. This is still not
	completely supported.

	* Added user preferences handling. Currently only two explicit
	preferences are supported: ConsultDocumentOnOpen and
	ConsultBeforeEvaluating. The frame of the Query dialog is remembered as
	an implicit preference.

	* User interface changes:
		-	Renamed menu items  "Load Window" to "Consult
			Document" (where Document is the main window title, if
			consultable).
		-	Added menu item "Consult All Changed Documents",
			added menu item "Consult On Open",
		-	Added checkbox "Consult Changed Documents Before Evaluation"
			and "All" evaluation button to "Evaluate Query..." dialog.
		-	Improved formatting of results (added solution counter).
		-	Fixed to disable/enable Next button correctly.
