Glimmerings.Tioga Thesis statement algorithms and techniques for complex tabular composition proposed extensions for mathematical notation and page composition Barnett's book Computing Surveys Document Formatting Article current processing model (lines -> pages) is inadequate and too limited penalties is indirect specification and requires more experience; prefer a more direct method need means to express relationships among objects: alignment, constrained distances, sizes as functions of other objects; frees user of low-level detail and permits automatic recalibration need way to express constraints on appearance of objects and to have sytem choose best appearance characteristics of documents are best described as properties of page spaces rather than properties of the objects; even three-dimensional spaces (for overlays) need more flexible methods for specifying nesting and arrangement of page spaces (hierarchal structures, rectangular spaces); more general solutions might help with layout problems now solved by specialized programs lack of efficient algorithms for implementing the desired functions; proved difficult to design a language to express the desired functions Seybold article on Tabular Composition Previous Work Tables in TEX Hlists and Vlists Tab stops TBL and Troff automatic layout mechanism Tables in SCRIBE Tab stops (?)
