[mcclim-announce] Announcing McCLIM 0.9.1 - "Mothering Sunday"
by McCLIM developers 06 Mar '05

06 Mar '05

The McCLIM developers are happy to release version 0.9.1 of McCLIM. It was extensively tested on SBCL (threaded and unthreaded), OpenMCL and CMUCL. It's also known to work with Allegro Common Lisp (tested with 6.2 Trial Edition). Lots of things changed since the last release, so I appended the release notes after the announcement. We're hoping to make this release the first in a series of time-boxed releases of McCLIM. You can get a tarball at <http://common-lisp.net/project/mcclim/downloads/mcclim-0.9.1.tar.gz>. Of course, we are looking forward to comments and bug reports. Please direct these at mcclim-devel <at> common-lisp.net. The current list of 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 0.9.1 - "Mothering Sunday": Changes to the McCLIM Installation Process ========================================== McCLIM now comes with a native ASDF system definition in mcclim.asd, along with the traditional (still ASDF-compatible) system.lisp. See INSTALL.ASDF for details. Changes to Backends =================== Support for Copy&Paste of selections (both into and out from McCLIM applications) in the X11 backend was added. Copying text from McCLIM into some applications (and vice versa) like KDE's Konsole is broken, unfortunately. Shift + left-mouse-drag and Shift + mouse-middle-down now activate a selection and paste in your McCLIM application, respectively. There is now rudimentary support for printing non-Latin1 characters to X11 ports on SBCL. Beagle, A new experimental backend using Mac OS X's Cocoa bindings was added. Note that this backend is still incomplete and breaks in some places. It is not loaded automatically. To try it out, consult Backends/beagle/README. Changes to the Manual ===================== A chapter on presentation types was added. The chapter on command tables was improved. Changes to Contributed Applications and Examples ================================================ Clouseau, a graphical Inspector application was added. The CLIM Listener saw many improvements, among these: package graphing, better directory stack handling and a new Edit Definition command. A Method Browser was added to the examples. 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 Finished 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. We do not have a true standard-tree-output-record type or the R-tree type of real CLIM, so some operations may be slow with lots of output records. 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. There is now a protocol in place for Drag-and-Drop of output records. Output recording inside formatting-tables now works. 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. Chapter 19, Bordered Output Bordered output is fully supported. The :move-cursor argument to surrounding-output-with-border is now working. 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 can suffer from performance problems because there are no spatially-organized compound output record types. The generic function incremental-redisplay is now implemented. 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. drag-output-record and dragging-output are now implemented. 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 "Exit" 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. own-window is not supported. The internal structure of accepting-values should be "culturally compatible" with real CLIM; if you have some spiffy hack, check the source. 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, frame-drag-and-drop-feedback and frame-drag-and-drop-highlighting are not implemented. execute-frame-command ignores the possibility that frame and the current frame might be different. display-command-menu isn't implemented. command-enabled is now 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.
