Information about the textmenu chooser -------------------------------------- Copyright (C) 2002-2003 Hewlett-Packard Co. Contributed by Last updated: 02/02/14 Chooser name: textmenu Command line option: -C textmenu Config file option: chooser=textmenu The textmenu chooser provides a facility whereby you can draw a colour boot screen, using line-drawing characters to give the impression of a dialog box, with a scrollable menu from which a boot image can be chosen via cursor up/down keys. A one-line input field is provided for additional parameter input. Menu entries are taken from the description= fields in the config file. The message file format is based on that used for syslinux/isolinux on ia32 platforms, which is copyright H. Peter Anvin. It is basically a text file containing text and graphic characters, along with some control codes to specify colour attributes, menu, and prompt field positions. There are two classes of message files; the main file, specified via message=, which includes menu and prompt field markers, and the additional help files which are invoked via function keys. Graphic characters are taken from the standard IBM VGA character set, and using an appropriate font makes file creation easier. Under Linux you can find a VGA font in the dosemu package. Included in the elilo source is sys2ansi.pl (taken from syslinux), which can be used to translate colour attributes such that they display correctly in an xterm. Valid control codes: 0x01 ^A Mark top left or bottom right of menu area. Current attributes at top left marker are used for inactive menu entries, current attributes when bottom right marker is found are used for the currently active menu attributes. 0x02 ^B Mark left- or right-hand end of the prompt field. Current attributes at the left had end are used to display and parameters entered. 0x0A ^J Linefeed, does implied carriage return. 0x0C ^L Clear screen 0x0D ^M Carriage return; ignored so files can be 'DOS' or 'UNIX' format. 0x0F ^O Attribute specfication; Two hex digits should follow this code, the first being the background colour required, the second the foreground. 0 = black 8 = dark grey 1 = dark blue 9 = bright blue 2 = dark green a = bright green 3 = dark cyan b = bright cyan 4 = dark red c = bright red 5 = dark purple d = bright purple 6 = brown e = yellow 7 = light grey f = white An example of a config file and message file are included in the examples directory.
