Free red line software for linux

The Fedora Project is an openly-developed project designed by Red Hat, open for general participation, led by a meritocracy, following a set of project objectives.
The goal of The Fedora Project is to work with the Linux community to build a complete, general purpose operating system exclusively from open source software. Development will be done in a public forum.
The project will produce time-based releases of Fedora Core about 2-3 times a year, with a public release schedule.
The Red Hat engineering team will continue to participate in building Fedora Core and will invite and encourage more outside participation than in past releases.
By using this more open process, we hope to provide an operating system more in line with the ideals of free software and more appealing to the open source community.
Main features:
- Support for the PowerPC (PPC) architecture.
- GCC 4.0

- Native Eclipse 3.1M6 (part of a free Java stack)
- MySQL 4.1
- PHP 5.0
- Xen 2 (virtualization to run multiple versions of an OS)
- GFS 6.1-0.pre22 (cluster file system)
- Evince 0.2.1 (universal document viewer)
- GDM 2.6 - Includes early login capability
- SELinux This release includes coverage for 80 new daemons by the targeted policy. There are changes to the handling of Booleans. The targeted policy is enabled by default.

GNU ed is a line-oriented text editor. GNU ed is used to create, display, modify and otherwise manipulate text files, both interactively and via shell scripts.
A restricted version of `ed, `red, can only edit files in the current directory and cannot execute shell commands. `ed is the `standard text editor in the sense that it is the original editor for Unix, and thus widely available.
Enhancements:
- The testsuite now exits unsuccesfully in case of error.
- Some minor problems in the manual page have been fixed.
- The GFDL has been added to the info file.

Image::Imlib2 is a Perl interface to the Imlib2 image library.

SYNOPSIS

use Image::Imlib2;

# create a new image
my $image = Image::Imlib2->new(200, 200);

# or load an image
$image = Image::Imlib2->load("foo.png");

# Enable the alpha channel support
$image->has_alpha(1);

# set a colour (rgba, so this is transparent orange)
$image->set_color(255, 127, 0, 127);

# draw a rectangle
$image->draw_rectangle(50, 50, 50, 50);

# draw a filled rectangle
$image->fill_rectangle(150, 50, 50, 50);

# draw a line
$image->draw_line(0, 0, 200, 50);

# set quality before saving
$image->set_quality(50);

# save out
$image->save(out.png);

# create a polygon
my $poly = Image::Imlib2::Polygon->new();

# add some points
$poly->add_point(0, 0);
$poly->add_point(100, 0);
$poly->add_point(100, 100);
$poly->add_point(0, 100);

# fill the polygon
$poly->fill();

# draw it closed on image
$image->draw_polygon($poly, 1);

# create a color range
my $cr = Image::Imlib2::ColorRange->new();

# add a color
my ($distance, $red, $green, $blue, $alpha) = (15, 200, 100, 50, 20);
$cr->add_color($distance, $red, $green, $blue, $alpha);

# draw it
my($x, $y, $width, $height, $angle) = (20, 30, 200, 200, 1);
$image->fill_color_range_rectangle($cr, $x, $y,
$width, $height, $angle);

Image::Imlib2 is a Perl port of Imlib2, a graphics library that does image file loading and saving as well as manipulation, arbitrary polygon support, etc. It does ALL of these operations FAST. It allows you to create colour images using a large number of graphics primitives, and output the images in a range of formats.

Image::Imlib2::Polygon and Image::Imlib2::ColorRange are described following Image::Imlib2 but may be referenced before their description.

Note that this is an early version of my attempt at a Perl interface to Imlib2. Currently, the API is just to test things out. Not everything is supported, but a great deal of functionality already exists. If you think the API can be tweaked to be a bit more intuitive, drop me a line!
Note that a development version of Imlib2 must be installed before installing this module.

Devel::ptkdb is a Perl debugger using a Tk GUI.
ptkdb is a debugger for perl that uses perlTk for a user interface.
Main features:
- Hot Variable Inspection
- Breakpoint Control Panel
- Expression List
- Subroutine Tree
SYNOPSIS
To debug a script using ptkdb invoke perl like this:
perl -d:ptkdb myscript.pl
Usage
perl -d:ptkdb myscript.pl
Code Pane
Line Numbers
Line numbers are presented on the left side of the window.
Lines thathave lines through them are not breakable. Lines that are plain text are breakable. Clicking on these line numbers will insert a breakpoint on that line and change the line number color to $ENV{PTKDB_BRKPT_COLOR} (Defaults to Red). Clicking on the number again will remove the breakpoint. If you disable the breakpoint with the controls on the BrkPt notebook page the color will change to $ENV{PTKDB_DISABLEDBRKPT_COLOR}(Defaults to Green).
Cursor Motion
If you place the cursor over a variable (i.e. $myVar, @myVar, or %myVar) and pause for a second the debugger will evaluate the current value of the variable and pop a balloon up with the evaluated result. This feature is not available with Tk400.
If Data::Dumper(standard with perl5.00502)is available it will be used to format the result. If there is an active selection, the text of that selection will be evaluated.

flactagger is a simple command line tool to tag FLAC files. flactagger is a tagger, not a tag editor/viewer.

flactagger is free software licenced under the GNU GPL.

Randomize Lines (rl) is a command-line tool that reads lines from an input file or stdin, randomizes the lines and outputs a specified number of lines. It does this with only a single pass over the input while trying to use as little memory as possible.
I wrote rl in my spare time mainly to be able to select a random audio file to play when my toast is done (script in combination with find and sleep). Another reason was to familiarize myself with autoconf and friends.
The most recent version of this page can be found at http://ch.tudelft.nl/~arthur/rl/.
Warning: rl is software in development. The command line options and default behavior may change between releases.
Another Warning: I have mostly lost interest in this project and am not planning on doing much development on it any more. I will however still accept patches and fix important bugs (this more or less contradicts the previous warning).
Enhancements:
- A dangerous example was removed from the manual page and was replaced by several benign ones.
