Free type in software for linux

MIME::Type is a definition of one MIME type.

SYNOPSIS

use MIME::Types;
my $mimetypes = MIME::Types->new;
my MIME::Type $plaintext = $mimetypes->type(text/plain);
print $plaintext->mediaType; # text
print $plaintext->subType; # plain

my @ext = $plaintext->extensions;
print "@ext" # txt asc c cc h hh cpp

print $plaintext->encoding # 8bit
if($plaintext->isBinary) # false
if($plaintext->isAscii) # true
if($plaintext->equals(text/plain) {...}
if($plaintext eq text/plain) # same

print MIME::Type->simplified(x-appl/x-zip) # appl/zip

MIME types are used in MIME entities, for instance as part of e-mail and HTTP traffic. Sometimes real knowledge about a mime-type is need. Objects of MIME::Type store the information on one such type.

This module is built to conform to the MIME types of RFCs 2045 and 2231. It follows the official IANA registry at http://www.iana.org/assignments/media-types/ and the collection kept at http://www.ltsw.se/knbase/internet/mime.htp

File type determination is a little KDE Service Menu that calls the GNU file command to retrieve Mime information from files, and presents it inside a standard KDE dialog.

This module supports versatile data and value types. Out of the ordinary it supports parameterised types (like databases have i.e. VARCHAR(80) ). When you try to feed a typed variable against some odd data, this module explains what he would have expected.

Banihstypos (yes, that is the name) is a simple game to teach you typing, FAST.
The project helps you improve your typing by letting you type in a randomly selected word which scrolls by on the screen at an increasing speed. If the word hits the laser, youll loose points.
Enhancements:
- fixed a incorrect declared array
- the first word was always the same
- counting of correctly typed words was incorrect

Audio::File::Type represents an audio filetype.

An instance of an object inherited from Audio::File::Type is returned by the constructor of Audio::File. This object currently provides access to the audio files information like its audio properties (bitrate, sample rate, number of channels, ...) and the data stored in the files tag, but also providing access to the raw audio data and other information should be easy to be implemented.

METHODS

new

Constructor. In fact you dont need to use it. Please use Audio::File which will call the appropriate constructor corresponding to the files type.

init

This method will be called by the constructor. Its empty by default and should be overwritten by inheriting subclasses to initialize themselfes.

name

Returns the name of the audio file.

is_readable

Checks whether the file is readable or not. At the moment its only used by the constructor, but it will be more usefull with later versions of Audio::File.

is_writeable

Checks whether the file is writeable or not. At the moment youll probably dont need to call this method, but itll be more usefull as soon as changing the audio file is implemented.

tag

Returns a reference to the files tag object. See the documentation of Audio::File::Tag to learn about what the tag object does.

audio_properties

Returns a reference to the files audio properties object. See the documentation of Audio::File::AudioProperties to get information about what the audio properties object does.

save

Saves the audio file. This is not yet implemented but it should remember me to do it at some time..

type

Returns the files type.

Tangram::Type::Extending is a Perl module for teaching Tangram about new types.

Tangram::Type is the root of a hierarchy of classes that are responsible mapping individual field to SQL entities (columns in the simplest cases). There is one Type object per persistent field.
Adding support for new types amounts to adding subclasses to Tangram::Type.

WRITING NEW TYPES

Tangram is organized in several subsystems, described below.

Schema is the repository for information about all the persistent aspects of a system: classes, inheritance relationships, fields, etc. It also contains graph-traversal algorithms, which are not currently documented.

Storage deals with objects as a whole: insertion, updating, multiple load detection, cycle handling, transactions, connections. It also serves as an entry point in the system. Storage does not manipulate fields directly.

Cursor deals with polymorphic retrieval of objects. It builds SELECT statements on the basis of the information in the hash. Cursor does not manipulate fields directly either.

The Type hierarchy deals with individual fields, and not with entire objects. More about it in a moment.

The Expr hierarchy deals with entities on the remote side; this includes expressions proper, Filters and Remotes.

Types are responsible for performing the mapping between a field of a given Perl type and a relational entity. The simplest Types merely transfer between one Perl field and one column. Sometimes it makes sense to have several mappings (and hence several Types) for the same Perl type; for example, Perl arrays can be mapped either using a link table, or one or several columns that live on the elements table.

Users dont deal with Type objects directly: they indicate that a series of fields should be mapped in a certain way by putting the fields under a given typetag in the field hash. The type registers itself with Tangram by adding a typetag in the %Tangram::Schema::TYPES hash. The value is the Type object. Up to now all Types have been singletons, but this is not a rule.

Anybody whos planning to write new Types should examine Scalar.pm first. It contains very simple mappings between one field and one column.

A Type must implement the methods described below. Keep the following facts in mind while reading further:

1. A Type is responsible for transfering all the *direct* fields for a given *class*. This excludes inherited fields. OTOH, the same Type can be called more than once for the same object, because the same Type may be used in several classes that appear in a particular objects inheritance graph.

File::Type::Builder is Perl module to parse mime-magic and generate code.

SYNOPSIS

my $build = File::Type::Builder->new();

while ( ) {
chomp;
my $parsed = $build->parse_magic($_);

my $code = $build->string_start($parsed);
(or string_offset or beshort)
}

Reads in the mime-magic file format and translates it to code. (This documentation would be longer if I really expected anyone other than me to run the code.)

ICMPInfo is a tool that uses ICMP type 13 and 17 to retrieve the current time of a remote host and its netmask.
