Not A Commander is yet another file manager modeled after the Norton Commander. Good integration with the command line is the primary goal.
This project is using the technology of Natural Stupidity for development: first get something working at all, then gradually improve it. My primary targets are the features that I personally would use. The features that I wont use anyway are not planned to be implemented at all (though if someone would contribute an implementation I would gladly accept it - as long as it does not break any of the things that I use).
Build
Run `make. That should build all the binary parts. The X11 headers are required for build. You may need to modify the Makefile for peculiarities of your particular system (directory names, libraries etc.).
Installation
Run `make install. By default the `nac binary is instaled into /usr/local/bin and the rest of files is installed into /usr/local/lib/nac (which is referred further as "the NAC directory").
These directory names can be changed in the Makefile. If the configuration file nac.sysrc was present in the NAC directory before installation, it will be moved into nac.sysrc.old.
Configuration
The default configuration of NAC can be changed with rc files. There are two rc files:
per system - nac.sysrc in the NAC directory per user - .nacrc in the users home directory
These files are common Tcl scripts that can be used to change the tunable values. NAC first sets the built-in values, then loads the system-wide rc file (if present), then loads the users rc file (if present). Thus the system-wide script can examine the built-in values and modify them was neccessary, and the users script can do the same thing with the result
of the system-wide script.
Be careful with the syntax, in case of an error in the rc scripts NAC wont start.
The list of the supported tunables and their values can be found at the top of tune.tcl. For now (the alpha phase of development) its expected to be quite liquid and change between snapshot releases. Probably some sort of versioning will be added after it stabilizes.
The sample system rc file included in a release contains only one setting - the name of font to use (most probably you dont have the font "koi9x16" which is the built-in default).
The default initial size of the window is defined by panel dimensions, variables named set panel:filespercolumn (number of rows in panels), panel:ncolumns (number of columns in panels), panel:columnwidth (width of a column in dots). The internal xterm is automatically resized to fit these dimensions. Alternative size in pixels or xterm characters can be
selected with command line options.
Enhancements:
- Various bugs were fixed and workarounds were included for bugs in glibc and Tk.

NetAddr::IP::Find is a Perl module to find IP addresses in plain text.

SYNOPSIS

use NetAddr::IP::Find;
$num_found = find_ipaddrs($text, &callback);

This is a module for finding IP addresses in plain text.

Functions

NetAddr::IP::Find exports one function, find_ipaddrs(). It works very similar to URI::Finds find_uris() or Email::Finds find_emails().

$num_ipaddrs_found = find_ipaddrs($text, &callback);

The first argument is a text to search through and manipulate. Second is a callback routine which defines what to do with each IP address as theyre found. It returns the total number of IP addresses found.

The callback is given two arguments. The first is a NetAddr::IP instance representing the IP address found. The second is the actual IP address as found in the text. Whatever the callback returns will replace the original text.

EXAMPLES

# For each IP address found, ping its host to see if its alive.
use Net::Ping;
my $pinger = Net::Ping->new;
my %pinged;
find_ipaddrs($text, sub {
my($ipaddr, $orig) = @_;
my $host = $ipaddr->to_string;
next if exists $pinged{$host};
$pinged{$host} = $pinger->ping($host);
});

while (my($host, $up) == each %pinged) {
print "$host is " . $up ? up : down . "n";
}


# Resolve IP address to FQDN
find_ipaddrs($text, sub {
my($ipaddr, $orig) = @_;
resolve_ip($ipaddr->to_string);
});

sub resolve_ip {
use Net::DNS;
# see perldoc Net::DNS for details
}

PHP feed finder is a PHP class that finds all the URLs for all RSS and ATOM feeds that appear on a given as well as OPML outline documents from a Web page.
The project will convert any relative links that are found into absolute links. The only required input is the URL of the Web page to be scanned for links.
Enhancements:
- ATOM feed links and OPML outline documents are now retrieved by the class, in addition to RSS links.

Xokoban project is my (C++) sokoban game for X11.
Main features:
- Undos right back to your first move
- Go to any level - you dont have to play them in order
- recording of solutions. If you solve a level or find a better solution, the new solution will be remembered
- can show the solution for any level, if one has been found
- a demo mode which shows all solutions or levels
- a nice-looking game board with a configurable color scheme, 4 are included.

MP3::Find is a Perl module to search and sort MP3 files based on their ID3 tags.

SYNOPSIS

# select with backend you want
use MP3::Find qw(Filesystem);

print "$_n" foreach find_mp3s(
dir => /home/peter/cds,
query => {
artist => ilyaimy,
title => deep in the am,
},
ignore_case => 1,
exact_match => 1,
sort => [qw(year album tracknum)],
printf => %2n. %a - %t (%b: %y),
);

This module allows you to search for MP3 files by their ID3 tags. You can ask for the results to be sorted by one or more of those tags, and return either the list of filenames (the deault), a printf-style formatted string for each file using its ID3 tags, or the actual Perl data structure representing the results.

There are currently two backends to this module: MP3::Find::Filesystem and MP3::Find::DB. You choose which one you want by passing its name as the argument to you use statement; MP3::Find will look for a MP3::Find::$BACKEND module. If no backend name is given, it will default to using MP3::Find::Filesystem.
Note: Im still working out some kinks in the DB backend, so it is currently not as stable as the Filesystem backend.

Note the second: This whole project is still in the alpha stage, so I can make no guarentees that there wont be significant interface changes in the next few versions or so. Also, comments about what about the API rocks (or sucks!) are appreciated.

Cabextract menu is just a little service menu that I put together for extracting MS .cab files.

It creates a directory with the same base name in the same directory as the .cab file and extracts to it. To use it, you have to have cabextract installed (and can be found here http://www.kyz.uklinux.net/cabextract.php.
