Irregular Operations Database is a project used for tracking flight delays.

Irregular Ops is a CGI script for intranet use to track irregular operations (flight delays) for scheduled airlines.

B::Generate is a Perl module which you can create your own op trees.


SYNOPSIS

use B::Generate;
# Do nothing, slowly.
CHECK {
my $null = new B::OP("null",0);
my $enter = new B::OP("enter",0);
my $cop = new B::COP(0, "hiya", 0);
my $leave = new B::LISTOP("leave", 0, $enter, $null);
$leave->children(3);
$enter->sibling($cop);
$enter->next($cop);
$cop->sibling($null);
$null->next($leave);
$cop->next($leave);

# Tell Perl where to find our tree.
B::main_root($leave);
B::main_start($enter);
}

WARNING

This module will create segmentation faults if you dont know how to use it properly. Further warning: sometimes I dont know how to use it properly.

There are lots of other methods and utility functions, but they are not documented here. This is deliberate, rather than just through laziness. You are expected to have read the Perl and XS sources to this module before attempting to do anything with it.
Patches welcome.

Malcolm Beatties B module allows you to examine the Perl op tree at runtime, in Perl space; its the basis of the Perl compiler. But what it doesnt let you do is manipulate that op tree: it wont let you create new ops, or modify old ones. Now you can.
Well, if youre intimately familiar with Perls internals, you can.

B::Generate turns Bs accessor methods into get-set methods. Hence, instead of merely saying

$op2 = $op->next;

you can now say

$op->next($op2);

to set the next op in the chain. It also adds constructor methods to create new ops. This is where it gets really hairy.

new B::OP ( type, flags )
new B::UNOP ( type, flags, first )
new B::BINOP ( type, flags, first, last )
new B::LOGOP ( type, flags, first, other )
new B::LISTOP ( type, flags, first, last )
new B::COP ( flags, name, first )

In all of the above constructors, type is either a numeric value representing the op type (62 is the addition operator, for instance) or the name of the op. ("add")
(Incidentally, if you know about custom ops and have registed them properly with the interpreter, you can create custom ops by name: new B::OP("mycustomop",0), or whatever.)

first, last and other are ops to be attached to the current op; these should be B::OP objects. If you havent created the ops yet, dont worry; give a false value, and fill them in later:

$x = new B::UNOP("negate", 0, undef);
# ... create some more ops ...
$x->first($y);

In addition, one may create a new nextstate operator with

newstate B::op ( flags, label, op)

in the same manner as B::COP::new - this will also, however, add the lineseq op.
Finally, you can set the main root and the starting op by passing ops to the B::main_root and B::main_start functions.

This module can obviously be used for all sorts of fun purposes. The best one will be in conjuction with source filters; have your source filter parse an input file in a foreign language, create an op tree for it and get Perl to execute it. Then email me and tell me how you did it. And why.

Data::Generate allows you to create various types of synthetic data by parsing "regex-like" data creation rules.

This module generates data by parsing given text statements (data creation rules). These statements are flexible and powerful regex-like way to control the production of synthetic data. Think about a program that instead of selecting data which matches a regex filter expression, produces it. For example, from the rule [a-c], the generator would produce the array a,b,c. The module works as following:

Specify data creation rules.
my $generator= Data::Generate::parse(VC(24) [0-9][2-3]);
At this step first you define one kind of output datatype (for ex. VC(24)= "output is a string with max length 24") and then with the rest of the expression define what it should look like. If parsing is successful a Data Generator object is instantiated.

Get data
my $Data= $generator->get_unique_data(10);
To really get the data, users must call the get_unique_data method by indicating the desired number of output values. The generator returns the values contained in an array reference. Please remark that output format is fixed according to the data type.

MP3-Database project is a tool to organize your MP3 collection. If you insert a CD with MP3 files in your CDROM drive, MP3DB can read all ID3 tags of the MP3 files.
With this information MP3DB creates a database which can be searched for a specific song, artist, or CD.
A GUI makes it easy to use the program. Any title found in the database can easily be added to a playlist or can instantly be played by XMMS.
Main features:
- MySQL (Is needed as database backend)
- Perl5
- Perl Modules:
- Tk
- Tk-MesgBox
- Tk-LabFrame
- Tk-Pane
- DBI
- MP3-Info
- Msql-Mysql-modules
- To play MP3 files the MP3 player XMMS should be installed on your system. MP3-Database can easily be adapted to other MP3 players
Enhancements:
- NEW Data Structure: The MySQL database is much more complex than before. I used 3 Tables for Artists, Albums and Titles to store the data. This ensures that I have no redundancies in the tables. This has also enabled me to store additional fields in the database (for example the date of birth of an artist, or the release year of an album).
- NEW Temporary Database: I added some tables to store all new artists, albums and titles in a temporary database. This enables the user to check the new entries before adding them to the permanent database.
- NEW FEATURES: Additional Artist and Album information can be stored in the database, MP3DB can now create a random playlist and a playlist with the top 20 MP3 titles, MP3DB can show you a statistic how many artists, albums and titles are stored in the database.

The Object Oriented Database Kit is a set of tools to help database applications developers to handle database communication, reporting, and printing. It has a solid, stable, and easy to use API. The project is also GUI toolkit agnostic and portable.

IA-32 Instructions Database is a description of all IA-32 instructions in the form of SQL source, specifying operands, arguments, prefixes, encoding details, and description.

This database information initially came from XI (http://verb.org.ua/xi/) project, which was generated using information from (unfortunately outdated) IA-32 Intel(r) Architecture Software Developers Manual 2002.

Current release is alpha, so your feedback and bug reports are highly appreciable!

How to Build

Basically, there is no much need to build ia-32-instrdb, as it is just an sql file. However, you can type `make and if you have sqlite properly installed, you will get sqlites ia32instrs.db file shortly.
