What's Goby?

Goby is an Emacs Lisp package to display large characters of TrueType/OpenType fonts on Emacs 22.

Since Goby can handle images, you can use Goby as a presentation tool. If you want to log the contents of a meeting, it is very convenient to display the log with Goby through a VGA projector.

There are two modes, Edit and View, for Goby. Edit mode is implemented as a minor mode while View mode as a major mode.

Internal representation

You should create a presentation material on the WYSIWYG manner with Goby. Created files are almost text. You can find file names corresponding to images in the files. The example above (left) includes images and centering, but its file is very simple as you can see below.

If you log the contents of a meeting with Goby, the log is just a text file. You can send the file without any modifications to the attendance by e-mail.

Edit mode

In Edit mode, size and color of characters are changed according to the number of TAB characters in the beginning of a line.

• If there is no TAB character, for instance, characters of the line become 6 percent of height and level 0's color. That is, if you just type characters, they become large and level 0's color.
• If one TAB character exists in the beginning of a line, characters of the line become 5 percent of height and level 1's color. Thus, inserting a TAB character in the beginning of a line, then typing characters results in making them be medium size and level 1's color.
• It is possible to insert images/bars/itemize signs, and centering.
• Simple mathematical expressions can be written.

View mode

View mode display one page with the page separator, "Control-L". Mode line and the minibuffer, which is not necessary for your presentation, go outside the screen.

Screen dump

Goby can create HTML files with screen dumps.

PostScript

Goby can create PostScript files whose images are very close to the displays. To convert a PostScript file to a PDF file, use Acrobat Distiller, etc.
