XLBlocks: a Block-based Formula Editor for Spreadsheet Formulas
No full textSpreadsheets are frequently used in industry to support critical business decisions. Unfortunately, they also suffer from error-proneness, which sometimes results in costly consequences. Experiments in the field of program education have shown that programmers tend to make fewer errors and can better focus on the logic of a program if they use a block-based language instead of a textual one. We hypothesize that a block-based formula editor could support spreadsheet users in a similar way. Therefore, we develop XLBlocks and conduct a think-aloud study with 13 experienced spreadsheet users from industry. Participants are asked to create and edit several formulas, using our block-based language. We then ask them to evaluate this editor using the Cognitive Dimensions of Notations framework. We found that for all dimensions the block-based formula editor received a better evaluation than the default text-based formula editor.Accepted author manuscriptSoftware Engineerin
Towards language-parametric semantic editor services based on declarative type system specifications
No full textEditor services assist programmers to more effectively write and comprehend code. Implementing editor services correctly is not trivial. This paper focuses on the specification of semantic editor services, those that use the semantic model of a program. The specification of refactorings is a common subject of study, but many other semantic editor services have received little attention. We propose a language-parametric approach to the definition of semantic editor services, using a declarative specification of the static semantics of the programming language, and constraint solving. Editor services are specified as constraint problems, and language specifications are used to ensure correctness. We describe our approach for the following semantic editor services: reference resolution, find usages, goto subclasses, code completion, and the extract definition refactoring. We do this in the context of Statix, a constraint language for the specification of type systems. We investigate the specification of editor services in terms of Statix constraints, and the requirements these impose on a suitable solver.Programming Language
Getting Published: Journey into a Relationship between Editor and Author
No full textLast year at the Inaugural TQR Conference, Sally and Dan conducted a workshop entitled Getting Published: Journey into an Editor\u27s Mind, highlighting what an editor thinks when she/he reviews a submitted manuscript to TQR. For the 2011 TQR Conference we will offer a variation of this presentation by including the voice of an author. Our workshop is entitled Getting Published: Journey into a Relationship between Editor and Author. In this workshop we will present a conversation between an author (Paige) and editor (Sally) to reveal an example of a relationship that develops between the two during the process of editorial review at TQR

WIRIS OM tools: a semantic formula editor
No full textWith the increasing reliance on computers for the automatic processing
of information a new method is needed for editing mathematical formulae.
We are used to WYSIWYG editors that produce beautiful presentations of
formulae and store the typesetting primitives rather than the meaning of the
formulas. However, new services such as database searching or calculation
web-services work best if they have access to the semantic information behind
a formula. This can only be done with a new generation of formula editors.
In this paper we present WIRIS OM Tools [17], a semantic oriented formula
editor which addresses these concerns. It is based on the OpenMath language
and a suitable transformation process between OpenMath and MathML ex-
pressions. Additionally, this approach adds new features for the users such
as error, type and syntax checking. The editor is currently being used in the
LeActiveMath and WebALT projects
