Ok. perform: is working for arithmetic but what about perform: itself? | x y plu perf wi args | x := 3. y := 4. plu := '+'. perf := 'perform:'. wi := 'with:'. args := Array new: 3. args at: 1 put: plu asSymbol; at: 2 put: wi asSymbol; at: 3 put: y. x perform: perf asSymbol withArguments: args. This code tells me that there is wrong number of arguments in permforn: How can I fix it? 2012/4/29 vittly <vitaly.kosenko(a)gmail.com> > Mmm thnx for replie!

[ANN] Styled Text Editor for Cuis 4.0 Smalltalk

by Bernhard Pieber

Dear Smalltalkers, I am very happy to announce that the Styled Text Editor for the brand new Cuis 4.0 is now available on GitHub [1]. The Styled Text Editor was first presented by me at last year's ESUG in Edinburgh [2]. Thanks to ESUG the presentation was recorded [3]. The Styled Text Editor is a framework for rich text editing using styles as known from popular word processors like Apple Pages or Microsoft Word. It features paragraph and character styles, allowing easy text formatting using styles only. It is intended for applications where users need to work with good looking rich text in a simple and fast way. Rich text commonly refers to text with formatting information like different fonts, sizes, alignments, and emphasis. To make editing as simple as possible instead of individual formatting information end users apply styles to parts of the text. Editing is made fast by keyboard shortcuts for text navigation, selection, and styles selection. Where possible the feel of widely used rich text editors is supported. It includes many features like - numbered and bulleted list paragraph styles - support for images - multiple level undo and redo - text completion using various glossaries including a dictionary of English with about 166.000 words - RTF clipboard (on OS X VMs with the ClipboardExtendedPlugin) The Styled Text Editor is developed in Cuis with the plan to eventually port it to Squeak and Pharo. The development of the Styled Text Editor inspired many changes to Cuis itself, and It is the first package to use the brand new DVCS based development process for external packages for Cuis 4.0. The idea and funding was provided by me, Bernhard Pieber and my company Software Generation. The implementation was done by Juan Vuletich, the mastermind behind Cuis. Thanks Juan for the close cooperation. It was and still is great fun to work with you. We are looking forward to feedback from you. Fork it on GitHub [1], create issues and send us pull requests. ;-) Cheers, Bernhard Pieber [1] https://github.com/bpieber/Cuis-StyledTextEditor [2] http://www.esug.org/wiki/pier/Conferences/2011/Schedule-And-Talks/StyledTex… [3] http://www.youtube.com/watch?v=pUoVbvwspi8&list=PL813665D04A2E4C0A&index=7&…
