Hi all Ruby-Tk Users and Developers. I am pleased to announce the first public release of Jeszra (0.1). [http://jeszra.sourceforge.net](http://jeszra.sourceforge.net) Jeszra is a visual design tool, written in Tcl/Tk, which combines 2D vector graphics and Graphical User Interface design. Jeszra generates RUBY (Ruby-Tk) wrapper classes for the components developed within Jeszra. Through Jeszra all Tcl/Tk control become available to a Ruby application. Jeszra also generates DocBook manual pages for the Ruby wrapper classes. Examples for this are the Runtime Library and Gestalt Items, both libraries are being developed with Jeszra and documented through it: [http://gestaltitems.sourceforge.net/ruby/index.html](http://gestaltitems.sourceforge.net/ruby/index.html) The latest Runtime Library and Gestalt Items are included in the jeszra01.tgz download package. Jeszra also contains a new composite library (Jeszra Library), for which Ruby wrapper classes are available: rubyJeszra01.tgz. [http://sunet.dl.sourceforge.net/project/jeszra/Jeszra%200.1/jeszra01.tgz](http://sunet.dl.sourceforge.net/project/jeszra/Jeszra%200.1/jeszra01.tgz) [http://sunet.dl.sourceforge.net/project/jeszra/Jeszra%200.1/rubyJeszra01.tgz](http://sunet.dl.sourceforge.net/project/jeszra/Jeszra%200.1/rubyJeszra01.tgz) Jeszra Overview: * * * Jeszra features a modular builder, with several backends. Extending Jeszra’s capabilities with another backend such as for FFI is considerable simple. Vector Graphics: TkZinc (3.3), TkPath (0.2 and 0.3), Tk Canvas (8.4 and 8.5) are being used for 2D-vector graphics. 2D vector graphics include transformations, gradients, transparency, images, embedded windows … Splines for TkZinc and TkPath (requires the tclsplines package). The GUI-part: Covers every Tcl/Tk window type featuring a configure command. 15+ geometry managers are supported. Jeszra also generates and edits contents for selected windows types: Tk Listbox, Hugelist, Rtl\_mlistbox, Tk Text … Jeszra generates: Tcl/Tk, Ruby, Lisp and Python wrapper classes for the designed composites. DocBook manual pages for the generated Tcl, Ruby, Lisp and Python code. Emacs Skeletons, Xcode textmacros for the Xcode Tcl-Mode Scalable Vector Graphics (SVG), Generating SVG requires the tdom and Img packages. SVG can be generated for TkZinc, TkPath, Tk Canvas, Tk Listbox … Screen shots (Img) are inserted for some windows, such as for Tile. Jeszra imports SVG into Tcl/Tk, TkPath 0.2 or 0.3, tdom and Img are required. Jeszra features an usual flexible User Interface, which allows for custom palettes, importing and exporting of palettes, a custom tools menu and a script recorder. The Jeszra website is currently under construction, but the Jeszra book is online: > **[Jeszra](https://jeszra.sourceforge.net/jeszra/)** > > Jeszra is an advanced vector graphics application written in Tcl/Tk. It generates source code for Tcl/Tk, Ruby, Python and Lisp. Supportive editing macros for Emacs and Apple® Xcode. Scalable Vector Graphics import and export. Generates DocBook... All elements of Jeszra’s User Interface are composite windows themselves and can be incorporated into other Tcl/Tk, Ruby-Tk, Tkinter, Ltk applications. The manual pages for Tcl are online at: [http://jeszra.sourceforge.net/pages/](http://jeszra.sourceforge.net/pages/) Have a nice day -roger ---

How did you generate them? Jeszra generates docbook refentry documents from the source code +separate docbook documents +svg. The used docbook fragments are distributed with Jeszra –inside the docbook sub-directory. The svgs are also generated with Jeszra. BTW: The ruby wrapper classes also support rdoc. -roger ---

Yes, there is a huge pile of work to push ahead for Jeszra. I myself still have to do some admin homework to do the sourceforge projects to … setting up the repositories and updating the gestaltitems online documentation as well as the libraries themselve. In relation with Ruby: The immediate thing is the lack of ruby examples inside the documentation, I did include lots of tcl examples, but only one for ruby sofar --the goolbar add command– Providing these examples and reviewing them is a lot of work. The entire documentation for the libraries and Jeszra is written in DocBook and all the DocBook manual pages are being generated by Jeszra. There are two DocBook related chapters inside the Jesra book explaining how the documentation is being created, the abridged chapter explains how to modify the generation process itself. That is: Everyone with a DocBook 4.5 toolchain is able to generate all the included manual pages, independently from me. For the current time I will collect those examples sent to me by email and publish them inside a newly created review section online for public review. I think the best way for this is to publish the email address of the original example-author within the example, so that each reviewer can directly communicate with the original authors. I also appriciate an example how to create a rubygem (I think there tutorial out there). rubygem, starpack, Asd … should be generated by Jeszra as-well. So this has to be done in Tcl not Ruby. Most other things are related with future versions. This is actual software design work I want to: Integrate Jeszra within every ruby-Tk, Lisp-Tk, Tcl/Tk, Python-Tk … application. I think I will have to work colsely with at least 3 projects from small to large, in order to define these integration procedure. Jeszra itself uses this for itself: The little red button allows full access to Jeszra’s internals–something akin to a live vivisection of Jeszra 😉 I want to: Allow editing Ruby-Tk, Tcl//Tk … Designs side-by-side to switch and transgress these projects freely. I have no glue yet how to accomplish that with Ruby-Tk. There is some very important code inside of Tkinter (Python) related to the Tix package. The package allows the subclassing of existing Tk windows, such an mechanism is also needed inside the wrapper classes, since in many cases may the need arise to access internal windows of a composite window. This is for example necessary for the bwidget tabset, were a frame is generated by the tabset and returned to the caller, in which then the dialog is being put. Runtime Library and GestaltItems do not generally need this, since I always prefer explicit creation rules over implicit ones. I like the way how Ruby-Tk casts the return values and properties when passing them from and to Tcl/Tk. The generated wrapper classes lack these ability --of course Jeszra has to generate those either. In the meantime this should be done by inheritance, lot of work. Thanks for asking -roger ---

Part 2: Since you seem to be located in Nippon, You could also help in translating Jeszra. The easy part is the online help and href to set F1 help on The included Ruby manual pages. Both parts are documented inside the first Runtime Library book available via download from the gestaltitmes [http://downloads.sourceforge.net/gestaltitems/rtlmanual11.pdf?modtime=1226427343&big\_mirror=0](http://downloads.sourceforge.net/gestaltitems/rtlmanual11.pdf?modtime=1226427343&big_mirror=0) This translation can be done within Jeszra. Use the red-button inside the general preferences and add href and help entries to the selected window like: “long info|tooltip info” These help entries are then stored inside your .jeszra configuration file, so make frequent backups of it or better put it under version control. This not yet possible normal text entries, I have to make some internal changes to activated it for normal text watch out for the next patch: translator.patch. It won’t be possible to translate non-window text, this way ☹ Jeszra should not only generate wrapper classes for Ruby, but actually also Ruby-Tk code. The code generation in Jeszra is split between a parser and composing backends. Teaching Jeszra to generate Ruby-Tk as-well requires only a new Ruby backend. See vg26/library/tclDumper.tcl and svgDumper.tcl for the Tcl and SVG backends. This is Tcl and there is no documentation for this yet, so you have to go with my comments. I am a fanatic on comments, so be better verbose and use a coherent style. I did put an emacs sekeleton into the documentation which auto generates Jeszra’s commentary style. Ask for this skeleton then I will send it to you. On second thought: the ruby examples for the documentation are the needed backend. Jeszra generates code based on the Runtime Library template mechansims (also described in the mentioned book). There are other models and similar composite libraries in Tcl/tk iwidgets to mention one. Jeszra should open and write also projects adhereing to these models, this will make it possible to create a proper documentation for these libraries and also wrapper classes. Since I have a conflicts of interest here: I am not writing these projects types myself, but they have to be written… With the excpetion of the examples don’t send any code to me, Just notify me that you have a delivery for Jeszra, what it is, where it is published --so that I can set a link on the website– That it is for Ruby, whether or not you like to join work with other developers working on the same thing. I’ll call you back for integration, so don’t expect any answer from me, this way I have more time free helping devolpers working on the tough parts. Thanks -roger
