Froglet is a source-level stepper for Common Lisp. Unlike previous steppers, which used pretty-printed reconstructions of definitions to show the progress of execution, Froglet uses the text from which the definition was read. This means that forms can be shown under evaluation in the right context, complete with comments and related functions. It also provides views onto the stack and onto the lexical environment of the form currently being evaluated. This paper describes the background to Froglet and how it is related to steppers for conventional languages, gives an overview of its implementation and interface, and shows that it could form a key addition to Lisp environments.

Narrative Hypermedia is...


Narrative Hypermedia
Narrative is concerned fundamentally with coherence, for instance, whether that be a fiction, an historical account or an argument, none of which 'make sense' unless they are put together in a coherent manner.

Hypermedia is the combination of hypertext for linking and structuring multimedia information.

Narrative Hypermedia is therefore concerned with how all of the above narrative forms, plus the many other diverse forms of discourse possible on the Web, can be effectively designed to communicate coherent conceptual structures, drawing inspiration from theories in narratology, semiotics, psycholinguistics and film.
