![]() You'll immediately notice that the onscreen representation of this document is almost identical to the appearance of the DVI file that was produced by formatting it using LaTeX. Figure 16-5 shows the LaTeX document that is used as an example throughout this section in the Lyx document processor. One of the coolest things about Lyx is its WYSIWYG (What You See Is What You Get) display and editing environment. Lyx provides a convenient graphical interface for creating and working with LaTeX documents, including conveniences such as being able to select document elements and styles from drop-down menus and reformat selected characters, paragraphs, and so on, all without having to remember the low-level LaTeX commands that perform these functions in your text. Figure 16-4 shows our sample LaTeX document being previewed in kdvi after having been formatted using Kile's Build C> QuickBuild command. Although you can configure Kile to use the standard xdvi DVI previewer (by choosing the Settings C> Configure Kile menu entry and modifying the command used to preview DVI files that is defined in Tools C> Build C> ViewDVI), you may simply want to install the kdvi package on your system if you are using Kile. The most important of these is kdvi, the KDE DVI file previewer. ![]() Figure 16-3 shows the same example LaTeX document in Kile.Īs a KDE application, Kile is configured to use other KDE-based TeX and LaTeX applications. Installing its KDE requirements on a standard GNOME-based Ubuntu system is well worth it, in my opinion. If you are new to LaTeX or simply want a sophisticated graphical environment for creating and working with LaTeX documents, I heartily recommend Kile, regardless of whether you're using Ubuntu or Kubuntu. Kile is a KDE-based application that provides an amazingly complete editing environment for standard LaTeX documents, providing wizards for creating various document elements (the table wizard is especially impressive), easy searching for document elements (and where they end), and a very cool LaTeX menu from which you can select and insert most LaTeX constructs with a simple mouse-click. If you are working with LaTeX documents, it's hard to beat the convenience of Kile or the Lyx document processor. ![]() J-1 ,■ Q^' iB Kile is a KDE-based application, so installing it on a standard GNOME-based Ubuntu desk-I " ■^-■f-V^ - as*®»® top system will also install all of its KDE dependencies, but disk space is cheap and Kile is an excellent LaTeX editing and development environment. Installing TeXmacs doesn't add anything to your menus, so you will have to execute TeXmacs by running the texmacs command from a command line. Installing Lyx adds the Lyx Document Processor command to the Office menu. ![]() (See Chapter 23, "Adding, Removing, and Updating Software," for more detailed information on installing applications using these tools.) Installing Kile adds the Kile - LaTeX Frontend command to the Office menu. Like texlive, these packages are not installed by default on your Ubuntu or Kubuntu system, but are easy enough to locate and install using the Synaptic Package Manager or Adept Manager. These are the Kile (the KDE Integrated LaTeX Environment), Lyx, and GNU TeXmacs applications, all of which are available in the Ubuntu repositories. It's a good thing that the folks in the world of open source have stepped up to provide graphical solutions for creating and working with documents in LaTeX format. Although command-line utilities such as TeX and LaTeX are easy to use, and the text-based format of TeX and LaTeX files makes them easy to exchange with users of many other computer systems and applications, it's hard to beat the convenience of a graphical application, especially when you're doing something such as word processing. As much of this book shows, it's a graphical world nowadays, and the Ubuntu and Kubuntu distributions provide all of the graphical applications that any computer user expects to find.
