Free descent freespace software for linux

XML::Descent is a Perl module for recursive descent XML parsing.

SYNOPSIS

use XML::Descent;

# Create parser
my $p = XML::Descent->new({
Input => $xml
});

# Setup handlers
$p->on(folder => sub {
my ($elem, $attr) = @_;

$p->on(url => sub {
my ($elem, $attr) = @_;
my $link = {
name => $attr->{name},
url => $p->text()
};
$p->stash(link => $link);
});

my $folder = $p->walk();
$folder->{name} = $attr->{name};

$p->stash(folder => $folder);
});

# Parse
my $res = $p->walk();

The conventional models for parsing XML are either DOM (a data structure representing the entire document tree is created) or SAX (callbacks are issued for each element in the XML).

XML grammar is recursive - so its nice to be able to write recursive parsers for it. XML::Descent allows such parsers to be created.

Typically a new XML::Descent is created and handlers are defined for elements were interested in

my $p = XML::Descent->new({ Input => $xml });
$p->on(link => sub {
my ($elem, $attr) = @_;
print "Found link: ", $attr->{url}, "n";
$p->walk(); # recurse
});
$p->walk(); # parse

A handler provides a convenient lexical scope that lasts until the closing tag of the element that triggered the handler is reached.

When called at the top level the parsing methods walk(), text() and xml() parse the whole XML document. When called recursively within a handler they parse the portion of the document nested inside node that triggered the handler.

New handlers may be defined within a handler and their scope will be limited to the XML inside the node that triggered the handler.

Beyond the Red Line project is a stand-alone total conversion for the award-winning Freespace 2 released by Volition and Interplay for the PC. It is based on the popular new tv-show Battlestar Galactica. No, not the one from the 70s.
Will I need Freespace 2 to play it?
No, Beyond the Red Line is a stand-alone conversion and will not require Freespace 2. All you need for playing will be included in the download.
Is it free?
Absolutely. The game is made by fans for the fans, no profit is being made from any part of the project. Although we could use some pizzas and coke to keep our mortal bodies running.
That about covers it... a BSG total conversion of FS2 that has just released a demo version. it plays really well and looks amazing. a must for any BSG fan.
Enhancements:
- This demo contains spoilers for the second season of BSG, so if you havent seen that season yet you should pass on this game for now.

print $img->png;

GD::Simple is a subclass of the GD library that shortens many of the long GD method calls by storing information about the pen color, size and position in the GD object itself. It also adds a small number of "turtle graphics" style calls for those who prefer to work in polar coordinates. In addition, the library allows you to use symbolic names for colors, such as "chartreuse", and will manage the colors for you.

The Pen

GD::Simple maintains a "pen" whose settings are used for line- and shape-drawing operations. The pen has the following properties:

fgcolor

The pen foreground color is the color of lines and the borders of filled and unfilled shapes.

bgcolor

The pen background color is the color of the contents of filled shapes.

pensize

The pen size is the width of the pen. Larger sizes draw thicker lines.

position

The pen position is its current position on the canvas in (X,Y) coordinates.

angle

When drawing in turtle mode, the pen angle determines the current direction of lines of relative length.

turn

When drawing in turtle mode, the turn determines the clockwise or counterclockwise angle that the pen will turn before drawing the next line.

font

The font to use when drawing text. Both built-in bitmapped fonts and TrueType fonts are supported.

fontsize

The size of the font to use when drawing with TrueType fonts.

One sets the position and properties of the pen and then draws. As the drawing progresses, the position of the pen is updated.

Methods

GD::Simple introduces a number of new methods, a few of which have the same name as GD::Image methods, and hence change their behavior. In addition to these new methods, GD::Simple objects support all of the GD::Image methods. If you make a method call that isnt directly supported by GD::Simple, it refers the request to the underlying GD::Image object. Hence one can load a JPEG image into GD::Simple and declare it to be TrueColor by using this call, which is effectively inherited from GD::Image:

my $img = GD::Simple->newFromJpeg(./myimage.jpg,1);

The rest of this section describes GD::Simple-specific methods.

$img->moveTo($x,$y)

This call changes the position of the pen without drawing. It moves the pen to position ($x,$y) on the drawing canvas.

$img->move($dx,$dy)
$img->move($dr)

This call changes the position of the pen without drawing. When called with two arguments it moves the pen $dx pixels to the right and $dy pixels downward. When called with one argument it moves the pen $dr pixels along the vector described by the current pen angle.

$img->lineTo($x,$y)

The lineTo() call simultaneously draws and moves the pen. It draws a line from the current pen position to the position defined by ($x,$y) using the current pen size and color. After drawing, the position of the pen is updated to the new position.

$img->line($dx,$dy)
$img->line($dr)

The line() call simultaneously draws and moves the pen. When called with two arguments it draws a line from the current position of the pen to the position $dx pixels to the right and $dy pixels down. When called with one argument, it draws a line $dr pixels long along the angle defined by the current pen angle.

$img->clear

This method clears the canvas by painting over it with the current background color.

$img->rectangle($x1,$y1,$x2,$y2)

This method draws the rectangle defined by corners ($x1,$y1), ($x2,$y2). The rectangles edges are drawn in the foreground color and its contents are filled with the background color. To draw a solid rectangle set bgcolor equal to fgcolor. To draw an unfilled rectangle (transparent inside), set bgcolor to undef.

$img->ellipse($width,$height)

This method draws the ellipse centered at the current location with width $width and height $height. The ellipses border is drawn in the foreground color and its contents are filled with the background color. To draw a solid ellipse set bgcolor equal to fgcolor. To draw an unfilled ellipse (transparent inside), set bgcolor to undef.

$img->arc($cx,$cy,$width,$height,$start,$end [,$style])

This method draws filled and unfilled arcs. See GD for a description of the arguments. To draw a solid arc (such as a pie wedge) set bgcolor equal to fgcolor. To draw an unfilled arc, set bgcolor to undef.

$img->polygon($poly)

This method draws filled and unfilled polygon using the current settings of fgcolor for the polygon border and bgcolor for the polygon fill color. See GD for a description of creating polygons. To draw a solid polygon set bgcolor equal to fgcolor. To draw an unfilled polygon, set bgcolor to undef.

$img->polyline($poly)

This method draws polygons without closing the first and last vertices (similar to GD::Image->unclosedPolygon()). It uses the fgcolor to draw the line.

$img->string($string)

This method draws the indicated string starting at the current position of the pen. The pen is moved to the end of the drawn string. Depending on the font selected with the font() method, this will use either a bitmapped GD font or a TrueType font. The angle of the pen will be consulted when drawing the text. For TrueType fonts, any angle is accepted. For GD bitmapped fonts, the angle can be either 0 (draw horizontal) or -90 (draw upwards).

For consistency between the TrueType and GD font behavior, the string is always drawn so that the current position of the pen corresponds to the bottom left of the first character of the text. This is different from the GD behavior, in which the first character of bitmapped fonts hangs down from the pen point.
This method returns a polygon indicating the bounding box of the rendered text. If an error occurred (such as invalid font specification) it returns undef and an error message in $@.

$metrics = $img->fontMetrics

($metrics,$width,$height) = GD::Simple->fontMetrics($font,$fontsize,$string)

This method returns information about the current font, most commonly a TrueType font. It can be invoked as an instance method (on a previously-created GD::Simple object) or as a class method (on the GD::Simple class).

When called as an instance method, fontMetrics() takes no arguments and returns a single hash reference containing the metrics that describe the currently selected font and size. The hash reference contains the following information:

xheight the base height of the font from the bottom to the top of
a lowercase m

ascent the length of the upper stem of the lowercase d

descent the length of the lower step of the lowercase j

lineheight the distance from the bottom of the j to the top of
the d

leading the distance between two adjacent lines

($delta_x,$delta_y)= $img->stringBounds($string)

This method indicates the X and Y offsets (which may be negative) that will occur when the given string is drawn using the current font, fontsize and angle. When the string is drawn horizontally, it gives the width and height of the strings bounding box.

$delta_x = $img->stringWidth($string)

This method indicates the width of the string given the current font, fontsize and angle. It is the same as ($img->stringBounds($string))[0]

($x,$y) = $img->curPos

Return the current position of the pen. Set the current position using moveTo().

$font = $img->font([$newfont] [,$newsize])

Get or set the current font. Fonts can be GD::Font objects, TrueType font file paths, or fontconfig font patterns like "Times:italic" (see fontconfig). The latter feature requires that you have the fontconfig library installed and are using libgd version 2.0.33 or higher.

As a shortcut, you may pass two arguments to set the font and the fontsize simultaneously. The fontsize is only valid when drawing with TrueType fonts.

$size = $img->fontsize([$newfontsize])

Get or set the current font size. This is only valid for TrueType fonts.

$size = $img->penSize([$newpensize])

Get or set the current pen width for use during line drawing operations.

$angle = $img->angle([$newangle])

Set the current angle for use when calling line() or move() with a single argument.

Here is an example of using turn() and angle() together to draw an octagon. The first line drawn is the downward-slanting top right edge. The last line drawn is the horizontal top of the octagon.

$img->moveTo(200,50);
$img->angle(0);
$img->turn(360/8);
for (1..8) { $img->line(50) }

$angle = $img->turn([$newangle])

Get or set the current angle to turn prior to drawing lines. This value is only used when calling line() or move() with a single argument. The turning angle will be applied to each call to line() or move() just before the actual drawing occurs.
Angles are in degrees. Positive values turn the angle clockwise.

$color = $img->fgcolor([$newcolor])

Get or set the pens foreground color. The current pen color can be set by (1) using an (r,g,b) triple; (2) using a previously-allocated color from the GD palette; or (3) by using a symbolic color name such as "chartreuse." The list of color names can be obtained using color_names().

$color = $img->bgcolor([$newcolor])

Get or set the pens background color. The current pen color can be set by (1) using an (r,g,b) triple; (2) using a previously-allocated color from the GD palette; or (3) by using a symbolic color name such as "chartreuse." The list of color names can be obtained using color_names().

$index = $img->translate_color(@args)

Translates a color into a GD palette or TrueColor index. You may pass either an (r,g,b) triple or a symbolic color name. If you pass a previously-allocated index, the method will return it unchanged.

$index = $img->alphaColor(@args,$alpha)

Creates an alpha color. You may pass either an (r,g,b) triple or a symbolic color name, followed by an integer indicating its opacity. The opacity value ranges from 0 (fully opaque) to 127 (fully transparent).
@names = GD::Simple->color_names

$translate_table = GD::Simple->color_names

Called in a list context, color_names() returns the list of symbolic color names recognized by this module. Called in a scalar context, the method returns a hash reference in which the keys are the color names and the values are array references containing [r,g,b] triples.

$gd = $img->gd

Return the internal GD::Image object. Usually you will not need to call this since all GD methods are automatically referred to this object.

($red,$green,$blue) = GD::Simple->HSVtoRGB($hue,$saturation,$value)

Convert a Hue/Saturation/Value (HSV) color into an RGB triple. The hue, saturation and value are integers from 0 to 255.

($hue,$saturation,$value) = GD::Simple->RGBtoHSV($hue,$saturation,$value)

Convert a Red/Green/Blue (RGB) value into a Hue/Saturation/Value (HSV) triple. The hue, saturation and value are integers from 0 to 255.

COLORS

This script will create an image showing all the symbolic colors.

StoCS is a service to control freespace on disk, mantain free space in a configurable level.

Works with three thresholds:

WARN: do a configurable action (dialog, message, alarm, ecc)
FDEL: deletion limit
LOWL: dimension to reach after deletion
If define must be LOWL < WARN < FDEL

Threshold unit can be:

Total number of file and/or subdiectory
Total dimension of controlle folder (Byte,Kbyte,Mbyte,ecc)
% of fre space on unit
Max age of files and/or subdirs (in this case LOWL is not used because all that exeeds is deleted)

Can work with a config file or wih command line parameters. Command line parameters overwrites config file values. Does not implements loop. Therefore you must use cron os similar.

Installation example

Copy stocs in /usr/local/bin
Copy stocs.conf in /usr/local/etc
Add to a cron.hourly (or a crontab):
/bin/su user -c "/usr/local/bin/stocs
-c /usr/local/stc/stocs.conf
&> /var/log/stocs.log"
In this case stocs runs every hour, using the configuration in stocs.conf, the output is written to log file /var/log/stocs.log

Common Text Transformation Library, CTTL for short, is a set of C++ classes and functions to understand and modify text data. Common Text Transformation Library implementation is based on STL classes and algorithms.
Concept of a substring plays major role in design of the text transformation library. CTTL substring is an object that interacts with fragments of text encapsulated by STL std::basic_string template class.
Template classes cttl::const_edge and cttl::edge, designed for constant and mutable data access, respectively, represent CTTL substrings. Substrings may be compared, inserted, deleted, or replaced across multiple text inputs. If content of text mutates, the substrings adjust their positions accordingly to the change. CTTL guarantees that substrings remain stable with respect to a potentially mutable text.
Within CTTL framework, a substring may be parsed with EBNF-like grammar. CTTL lexical analysis engine generates a stream of substrings corresponding to the parsed symbols. BNF and EBNF grammars can be written directly in C++.
Template meta-programming and operator overloading offer features to write C++ expressions that describe grammar rules. No additional steps of parsing, compiling, or generating source code are required. Compiled CTTL program implements LL(INF)-parser, the recursive-descent parser with infinite lookahead.
Enhancements:
- This release focuses on documentation enhancements, which include multiple documentation improvements and revisions.
- An alphabetical index of all CTTL facilities was added: http://cttl.sourceforge.net/documentation_idx.html.

Spirit is an object oriented recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow us to approximate the syntax of Extended Backus Normal Form[1] (EBNF) completely in C++.
Parser objects are composed through operator overloading and the result is a backtracking LL(inf) parser that is capable of parsing rather ambiguous grammars.
The Spirit framework enables a target grammar to be written exclusively in C++. Inline EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable. In retrospect, conventional compiler-compilers or parser-generators have to perform an additional translation step from the source EBNF code to C or C++ code.
Spirit is part of Boost Libraries, a peer-reviewed, open collaborative development effort.
Enhancements:
- Fixed bug where a match is a variant.
- added Jamfile/Jamrules from CVS to spirit-1.8.1/
- added boost-build.jam from boost to spirit-1.8.1/
- disabled template multi-threading in libs/spirit/test/Jamfile
- added a boost-header-include rule (from spirit-header-include) pointing to miniboost in libs/spirit/test/Jamfile
- Fixed if_p inconsistency
