    TEXmacs interfaces to Maxima, MuPAD and REDUCE A. G. Grozin Budker Institute of Nuclear Physics, Novosibirsk 630090, Russia [email protected] Abstract GNU TEXmacs is a free wysiwyg word processor providing an excellent typesetting quality of texts and formulae. It can also be used as an interface to Computer Algebra Systems (CASs). In the present work, interfaces to three general-purpose CASs have been implemented. 1 TEXmacs GNU TEXmacs [1] is a free (GPL) word processor which typesets texts and mathematical formulae with very high quality (like LAT X), • E emphasizes the logical structure of a document rather than its appearance (like • LATEX), is easy to use and intuitive (like typical wysiwyg word processors), • arXiv:cs/0107036v2 [cs.SC] 31 Jul 2001 can be extended by a powerful programming language (like Emacs), • can include PostScript figures (as well as other figures which can be converted • to PostScript), can export LAT X, and import LAT X and html, • E E supports a number of languages based on Latin and Cyrillic alphabets. • It uses TEX fonts both on screen and when printing documents. Therefore, it is truly wysiwyg, with equally good quality of on-screen and printed documents (in contrast to LyX which uses X fonts on screen and calls LATEX for printing). There is a similar commercial program called Scientific Workplace (for Windows). TEXmacs can also be used as an interface to any CAS which can generate LATEX output. It renders LATEX formulae on the fly, producing CAS output with highest 1 typesetting quality (better than, e.g., Mathematica, which uses fixed-width fonts for formula output).

  • “Real” Page Numbers to a Reflowable Kindle Textbook

    “Real” Page Numbers to a Reflowable Kindle Textbook

    How to Use Adobe InDesign CC to Add “Real” Page Numbers to a Reflowable Kindle Textbook with an Index, so that Index Entries Correspond to Print Edition Page Numbers, and Link to the Specific Text relevant to the Given Entry Topic Why do textbook authors/publishers require “real page numbers”? So readers can know what page they are on, so scholars can cite the page in academic papers, and students be sure they are reading the class assignments. Note that since a “page” in a book translates into multiple “locations” in a reflowable eBook like the E-ink Kindles, the page numbers in an index topic entry are not actually linked to the page number (whether visible or invisible) in the eBook. They are linked to the topic material - the index marker embedded by InDesign at a specific word. The fact that this link may go to a position in the text that is a few “locations” from the actual page number is not a bug, it’s a feature. Links go to “relevant paragraphs,” not page numbers, as Amazon requires. Kindle Digital Publishing Guidelines strongly recommend that the publisher remove some page numbers from reflowable E-ink Kindles, specifically those in the Table of Contents. This is because the typical mobi eBook does not have page numbers. When they do have page numbers, Amazon should support them in the ToC, as they do in the Index. Unfortunately, communication with KDP support is poor. KDP’s own conversion process now removes page numbers from the Table of Contents even though the publisher leaves them in and requests the Kindle Real Page Numbers feature, which supports the Go to Page feature and “page-flips” with page numbers.
