FbTerm is a fast terminal emulator for linux with frame buffer device. Features include: mostly as fast as terminal of linux kernel while accelerated scrolling is enabled on framebuffer device ... [More] select font with fontconfig and draw text with freetype2, same as Qt/Gtk+ based GUI apps dynamicly create/destroy up to 10 windows initially running default shell record scrollback history for every window auto-detect text encoding with current locale, support double width scripts like Chinese, Japanese etc switch between configurable additional text encodings with hot keys on the fly copy/past selected text between windows with mouse when gpm server is running change the orientation of screen display, a.k.a. screen rotation lightweight input method framework with client-server architecture background image for eye candy News2009-04-26 Release version 1.5added support for text rendering with backround image added command-line arguments to customize command executed in sub-window added Alt-Fn and all FbTerm's shortcuts support when input method is actived added option "-v/--verbose" to show some useful information fixed some text color issues with version 1.4 fixed encoding selection error when locale is C/POSIX fixed a bug where screen is cleared on startup even in inactive tty fixed a bug where variable HOME is not defined From version 1.5, user can execute FbTerm with fbterm [options] [--] [command [arguments]]. Normally FbTerm checks the SHELL variable. If that is not set, it tries to use the user's login shell program specified in the password file. If that is not set, /bin/sh will be used. command [arguments] may be given to override the built-in choice of shell program. You should use the -- argument to separate FbTerm's options from the arguments supplied to the command. Backround image support has been added in this version. FbTerm dosn't load and parse any image file with various formats directly, instead it takes a screenshot of frame buffer device on startup if variable FBTERM_BACKGROUND_IMAGE is defined, then uses this screenshot as the background for text rendering. In order to enable background image support, user should first put a image to frame buffer device with a image viewer. The updated FbTerm's man page contains a demo script using fbv. Here is a screenshot: 2009-03-14 Release version 1.4improved text rendering performence added private escape sequences for 256 color mode support added a option "font-width" to adjust character cell width added support for older 2.2/2.4 kernel fixed a crash bug with bitmap fonts fixed a configure failure in cross-compiling environment xterm has a 256 color mode extension, FbTerm also add it in this version. But xterm's 256 color escape sequences conflit with the linux sequences implemented by FbTerm, so private escape sequences were introduced to support this feature: ESC [ 1 ; n } set foreground color to n (0 - 255) ESC [ 2 ; n } set background color to n (0 - 255) ESC [ 3 ; n ; r ; g ; b } set color n to (r, g, b) , n, r, g, b all in (0 - 255)and a new terminfo database entry named "fbterm" was added to use these private sequences, all program based on terminfo should work with it. FbTerm defaultly sets environment variable "TERM" to value "linux", you need run "TERM=fbterm /path/to/program" to enable 256 color mode. 2008-12-20 Release version 1.3added command line arguments to change option values added client-server based input method framework added screen rotation support added support for visual type DIRECTCOLOR used by ATI cards (thanks for Witek's patch) fixed a bug that user can't input some unicode characters fixed a bug of maybe not restore original console state after FbTerm exited fixed several trivial bugs added using filesystem capability attributes offered by kernel 2.6.27, instead of setting set-user-ID bit on FbTerm decreased memory usage of every shell instance by changing size of the struct saving every charater's attribute from 4 to 2 bytes In version 1.3, FbTerm first uses option value specified in command line arguments, then in the configure file $HOME/.fbtermrc. The format of configure file has been changed from "option_name=val" to "option-name=val", and several option names been modified to keep conformance with command line arguments. Old $HOME/.fbtermrc should be deleted when your begin to run this new version. Instead of adding input method directly in FbTerm, a client-server based input method framework is designed to do this work. FbTerm acts as a client, standalone IM program as a server, they run in seperated processes and communicate each other with predefined IM messages in a unix socket pair. FbTerm provides a guide document and a IM demo to help developers understand the IM framework, and the fundentional sources of demo will make IM development more easier. Here is the screenshot of this demo on clockwise 270 degrees rotated screen. Everyones who want to write IM servers for FbTerm are very welcome. At present, two IM servers are under heavy development. If you are a normal IM user, please stay tuned! 2008-10-12 Release version 1.2improved escape and control sequences compability with linux console, support sequences for changing the color palette and cursor shape added option to adjust default cursor shape and flash interval added option to modify chars considered as part of a word while auto-selecting text added handle signal SIGHUP, FbTerm will exit normally while shutdown system directly in it fixed a freeze issue caused by changing console winsize under kernel 2.6.26 fixed a crash bug when font size is greater than screen size cleaned text selection code and fixed a crash bug fixed a error of not repainting screen when switch back to virtual console which FbTerm running on, but FbTerm not have active window fixed a buffer overflow issue which may cause denial of service via application crash FbTerm now support linux control sequence for changing the color palette, let's see a example: if [ "$TERM" = "linux" ]; then echo -en "\e]P0222222" #black echo -en "\e]P8222222" #darkgrey echo -en "\e]P1803232" #darkred echo -en "\e]P9982b2b" #red echo -en "\e]P25b762f" #darkgreen echo -en "\e]PA89b83f" #green echo -en "\e]P3aa9943" #brown echo -en "\e]PBefef60" #yellow echo -en "\e]P4324c80" #darkblue echo -en "\e]PC2b4f98" #blue echo -en "\e]P5706c9a" #darkmagenta echo -en "\e]PD826ab1" #magenta echo -en "\e]P692b19e" #darkcyan echo -en "\e]PEa1cdcd" #cyan echo -en "\e]P7ffffff" #lightgrey echo -en "\e]PFdedede" #white clear #for background artifacting fiAs with all escape codes, it begins with a little prefix indicating what the escape is actually doing: in this case "\e]P", which is the "set color" escape. The format for the data is "XRRGGBB" where X is the number of the color to modify (in hex). This is a standard 16 color notation, which I have commented above. RRGGBB indicates the red/green/blue values (0-255). To reset the color palette, use "\e]R". 2008-08-23 Release version 1.1add configurable additional text encoding support and switch between them with hot keys add option in configure file to let user adjust max scroll-back history lines of every window fixed cursor drawing issue while shell command line containing double width characters fixed a spelling error in source for older kernel support fixed a compile failure while kernel headers version less than 2.6.24 2008-07-05 Release version 1.0 [Less]

Lecturer is an eBook reader for portable devices that not only displays the text in an easy-to-read font with adjustable margins and spacing, but is also able to read it out loud! The speech ... [More] output code uses the Loquendo TTS system installed on recent TomTom Go mobile GPS navigation units. Developed for the TomTom Go 730, it should also work on 930 models. While the text-to-speech component is closely tied to that platform, the plain text viewer is easily ported to any system with a Linux framebuffer device or SDL. Installation and usage [Less]
