[ann] [mcclim-announce] [mcclim-devel] Announcing McCLIM 0.9.2 "Laetare Sunday"
by McCLIM developers 26 Mar '06

26 Mar '06

The McCLIM developers are happy to release version 0.9.2 of McCLIM. It was tested on SBCL (both threaded and unthreaded), OpenMCL, CMUCL, Scieneer CL, and Allegro Common Lisp (ANSI mode only). Get the tarball at <http://common-lisp.net/project/mcclim/downloads/mcclim-0.9.2.tar.gz> or install McCLIM via asdf-install. We are looking forward to your comments and bug reports. Please send them to mcclim-devel(a)common-lisp.net. The list of currently known bugs can be found at <http://mcclim.cliki.net/Bug>. Have fun using McCLIM (and build good things with it), The McCLIM developers. RELEASE NOTES FOR McCLIM 0.9.2, "Laetare Sunday": Compatibility ============= This release works on CMUCL, SBCL, CLISP, OpenMCL, Allegro CL, LispWorks, and the Scieneer CL, using the CLX X Window bindings. Changes to the Install Process ============================== Implementation-specific INSTALL.* files were removed. Generic and implementation-specific Installation instructions were improved and merged into the file INSTALL. This release requires the "spatial-trees" library by Christophe Rhodes. Get it via asdf-install or at http://cliki.net/spatial-trees. Changes to Backends =================== Copy & Paste code in the CLX backend was improved and should now adhere more strictly to ICCCM. Support for connecting to a ssh-forwarded display was restored. Several unused parts (marked with #+unicode) of the CLX backend were removed, thus restoring buildability on installations of clisp that have the unicode feature turned on. Double buffering for panes was implemented. To use it, create panes with the :double-buffering t initarg. There is now rudimentary support for entering non-Ascii characters from X11 ports using SBCL CLX (a.k.a. telent CLX). McCLIM ships experimental support for TrueType font rendering using the FreeType libraries and the free Bitstream Vera fonts. To use it, link Experimental/freetype/mcclim-freetype.asd to one of your asdf:*central-registry* directories and load the "MCCLIM-FREETYPE" system. An experimental "Null" backend was added that should allow testing of CLIM functionality without requiring a GUI environment to run. Changes to the Documentation ============================ A new chapter on contributed applications was added. Several new figures and examples were added to the manual Clemens Fruhwirth added a CLIM tutorial paper called "A Guided Tour to CLIM". It is available in Doc/Guided-Tour/. Changes to Contributed Applications and Examples ================================================ New application: A CLIM Debugger (by Peter Mechlenborg). It resides in Apps/Debugger/. New application: Functional-Geometry by Frank Buss and Rainer Joswig. It resides in Apps/Functional-Geometry/. The Inspector now is now able to disassemble functions and inspect pathnames. The Listener can now produce vertically-aligned graphs. The Scigraph application now builds on SBCL again. A demo for drag-and-drop-translators was added. Further additions to McCLIM =========================== There is now a test suite, located in Tests/. It contains tests for regions, bounding rectangles, transformations, commands, and the PostScript backend. With the addition of the Null backend, we hope to add several more tests for more chapters of the CLIM spec. New Extension "conditional-commands": allows activation/deactivation of commands when other commands are invoked. It resides in Extensions/conditional-commands/. Status of the CLIM 2 Spec Implementation ======================================== Here is a list of what we think works, organized by chapters and sections of the CLIM 2 specification. Chapter 3 Regions Mostly finished. There are some troublesome parts of the specification that may not be implemented for all possible regions, for instance region-contains-region-p. There may not be an efficient way of implementing this function for all kinds of regions. Chapter 4, Bounding rectangles Finished Chapter 5, Affine transformations Finished Chapter 6, Overview of window facilities Finished Chapter 7, Properties of sheets Finished, though the correct behavior of sheet transformations may not have been tested. Chapter 8, Sheet protocols Finished Chapter 9, Ports, Grafts, and Mirrored sheets Finished Chapter 10, Sheet and medium output facilities Finished Chapter 11, Text styles Mostly complete. There is now experimental support for device font text styles (via make-device-font-text-style) for the CLX, PostScript, and CLX+FreeType backends. Chapter 12, Graphics Finished Chapter 13, Drawing in Color I am note sure about the state of this. I thought we were doing only full opacity and full transparency, but I see traces of more general designs. Chapter 14, General Designs The composition of designs is not supported. We do support regions as designs. Chapter 15, Extended Stream Output Extended output streams are fully supported. Chapter 16, Output Recording Output recording is mostly implemented. This release ships with a standard-tree-output-record type for the first time. The tree output record type speeds up point- and region-based queries, but slows down insertion of output records by a bit. make-design-from-output-record is not implemented. *Note*: the coordinates in output records are relative to the stream. This is in conformance with the Spec, but not necessarily compatible with other CLIM implementations. Chapter 17, Table Formatting Table formatting is completely implemented. Chapter 18, Graph Formatting Graph formatting is fully implemented. The :hash-table argument to format-graph-from-roots is ignored. Support for a :dag graph type was added, as was support for vertically oriented graphs and support for the :arc-drawer argument to format-graph-from-roots. Chapter 19, Bordered Output Bordered output is fully supported. Chapter 20, Text Formatting With the exception of the :after-line-break-initially argument to filling-output, this chapter is fully implemented. Chapter 21 Incremental Redisplay The updating-output interface to incremental redisplay is implemented. McCLIM makes no effort to move i.e., bitblit, output records; they are always erased and redrawn if their position changes. This is much more compatible with support for partial transparency. The :x, :y, :parent-x and :parent-y arguments to redisplay-output-record are ignored. McCLIM follows the spirit of 21.3 "Incremental Redisplay Protocol", but we have not tried very hard to implement the vague description in the Spec. augment-draw-set, note-output-record-child-changed and propagate-output-record-changes-p are not implemented. Incremental redisplay in McCLIM may still suffer from performance problems, despite the presence of spatially-organized compound output record types. Chapter 22, Extended Stream Input The implementation of extended input streams is quite complete. (setf* pointer-position) is not implemented. There is no stream numeric argument, so that slot of the accelerator-gesture condition is always 1. Chapter 23 Presentation Types Most of the literal specification of this chapter is implemented. Specific accept and present presentation methods for some types are not implemented, so the default method may be surprising. The output record bounding rectangle is always used or highlighting and pointer testing. presentation-default-processor is not implemented. The presentation method mechanism supports all method combinations. The body of a presentation method is surrounded with a block of the same name as the presentation method, not just the magic internal name. The method by which presentation type parameters and options are decoded for the method bodies is a bit different from real CLIM. In particular, you cannot refer to the type parameters and options in the lambda list of the method. The NIL value of presentation-single-box is now supported. Presentation type histories are now partially implemented. The gesture C-M-y should recall the last entered presentation. define-drag-and-drop-translator is now implemented. Chapter 24 Input Editing and Completion Facilities with-input-editor-typeout is not implemented. The noise strings produced by input-editor-format and the strings produced by presentation-replace-input are not read-only. This could lead to interesting "issues" if the user edits them. Only a few of the suggested editing commands are implemented. An additional command that is implemented is control-meta-B, which drops into the debugger. add-input-editor-command is not implemented. with-accept-help is not implemented. Chapter 25 Menu Facilities The protocol is implemented, but McCLIM doesn't use it to draw command table menus. Chapter 26 Dialog Facilities McCLIM contains a basic, somewhat buggy implementation of accepting-values. There is little user feedback as to what has been accepted in a dialog. The user has to press the "OK" button to exit the dialog; there are no short cuts. There are no special accept-present-default methods for member or subset presentation types. Command-buttons are not implemented. There is no gadget-based implementation of accepting-values. The internal structure of accepting-values should be "culturally compatible" with real CLIM; if you have some spiffy hack, check the source. :own-window is now supported in accepting-values. Chapter 27 Command Processing command-line-complete-input is not implemented (the functionality does exist in the accept method for command-name). display-command-table-menu and menu-choose-command-from-table are not implemented. Menu-command-parser is not implemented, though the functionality obviously is. Nothing is done about partial menu commands. There is no support for numeric arguments. The command-or-form presentation type is not implemented. Chapter 28 Application Frames raise-frame, bury-frame and notify-user are not implemented. :accept-values panes are not implemented. frame-maintain-presentation-histories is not implemented. frame-drag-and-drop-feedback and frame-drag-and-drop-highlighting are now implemented. execute-frame-command ignores the possibility that frame and the current frame might be different. display-command-menu isn't implemented. Chapter 29 Panes Due to the way the space-allocation protocol is implemented, it is not easy to create application-specific layout-panes. Client code needs to know about :AROUND methods to compose-space, but they are not mentioned in the spec. restraining-pane is partially implemented. Chapter 30 Gadgets This chapter is implemented. with-output-as-gadget is not quite working yet, but it was improved since the last release. _______________________________________________ mcclim-devel mailing list mcclim-devel(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/mcclim-devel _______________________________________________ mcclim-announce mailing list mcclim-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/mcclim-announce

[ann] [flexi-streams-announce] New version 0.5.3 (Was: in-memory streams have no way to set external-format?)

You forgot that you have to create a flexi stream first - in-memory streams happen to be provided by the same library but they're something different. Use MAKE-FLEXI-STREAM to turn them into flexi streams. > And are string-backed in-memory streams even allowed? No. CL already has WITH-INPUT-FROM-STRING... :) > Thanks for your time and for developing flexi-streams. In return, I > hope to be able to buy you a beverage of your choice in Hamburg (-: Nice. Looking forward to seeing you there!

[ann] [beep-announce] mostly successful installation on SBCL / Linux

I just installed cells-gtk-2006-02-16 on Fedora Core 4 using SBCL 0.9.10. I originally tried SBCL 0.9.3 but got fatal errors. I did get one condition raised regarding redefinition of a constant, but allowing it didn't seem to cause a problem. When I ran (test-gtk::gtk-demo) I got the following error: * (test-gtk::gtk-demo) debugger invoked on a CFFI:LOAD-FOREIGN-LIBRARY-ERROR in thread #<THREAD "initial thread" {A68C4C9}>: Unable to load foreign library: libcellsgtk.so Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. restarts (invokable by number or by possibly-abbreviated name): 0: [RETRY ] Try loading the foreign library again. 1: [USE-VALUE] Use another library instead. 2: [ABORT ] Exit debugger, returning to top level. (CFFI::HANDLE-LOAD-FOREIGN-LIBRARY-ERROR "libcellsgtk.so" "Unable to load foreign library: ~A" "libcellsgtk.so") 0] 2 Attempting to build libcellsgtk.so as described in INSTALL.TXT resulted in another error: ~> cd src/build/cells-gtk-2006-02-16/root/gtk-ffi/ ~/<2>cells-gtk-2006-02-16/root/gtk-ffi> make gcc -c gtk-adds.c `pkg-config --cflags --libs gtk+-2.0` gtk-adds.c: In function 'gtk_adds_color_new': gtk-adds.c:75: warning: incompatible implicit declaration of built-in function 'malloc' gcc: -lgtk-x11-2.0: linker input file unused because linking not done gcc: -lgdk-x11-2.0: linker input file unused because linking not done gcc: -latk-1.0: linker input file unused because linking not done gcc: -lgdk_pixbuf-2.0: linker input file unused because linking not done gcc: -lm: linker input file unused because linking not done gcc: -lpangoxft-1.0: linker input file unused because linking not done gcc: -lpangox-1.0: linker input file unused because linking not done gcc: -lpango-1.0: linker input file unused because linking not done gcc: -lgobject-2.0: linker input file unused because linking not done gcc: -lgmodule-2.0: linker input file unused because linking not done gcc: -ldl: linker input file unused because linking not done gcc: -lglib-2.0: linker input file unused because linking not done gcc -shared -o libcellsgtk.so gtk-adds.o `pkg-config --cflags --libs gtk+-2.0` I downloaded the pre-built library from the cells-gtk site, copied it to /usr/lib, and reran (test-gtk::gtk-demo) successfully.
