Free readable format software for linux

Common Data Format is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion.
It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Enhancements:
- Adds new sets of APIs to allow Standard Interface to interact with zVariables and other CDF-related information.
- Adds MingW and FreeBSD ports.
- Adds support for Intel C++ and Fortran for Linux.
- Adds the ability to create legacy CDF 2.7 files.
- Fixes a bug that prevented directories from having .cdf or .skt extensions.

Fortran::Format is a Perl module to read and write data according to a standard Fortran 77 FORMAT.

SYNOPSYS

use Fortran::Format;

my $f = Fortran::Format->new("2(N: ,I4,2X)");
print $f->write(1 .. 10);
# prints the following:
# N: 1 N: 2
# N: 3 N: 4
# N: 5 N: 6
# N: 7 N: 8
# N: 9 N: 10

# if you dont want to save the format object,
# just chain the calls:
Fortran::Format->new("2(N: ,I4,2X)")->write(1 .. 10);

This is a Perl implementation of the Fortran 77 formatted input/output facility. One possible use is for producing input files for old Fortran programs, making sure that their column-oriented records are rigorously correct. Fortran formats may also have some advantages over printf in some cases: it is very easy to output an array, reusing the format as needed; and the syntax for repeated columns is more concise. Unlike printf, for good or ill, Fortran-formatted fields never exceed their desired width. For example, compare

printf "%3d", 12345; # prints "12345"
print Fortran::Format->new("I3")->write(12345); # prints "***"

This implementation was written in pure Perl, with portability and correctness in mind. It implements the full ANSI standard for Fortran 77 Formats (or at least it should). It was not written with speed in mind, so if you need to process millions of records it may not be what you need.

DateTime::Format::Pg is a Perl module to parse and format PostgreSQL dates and times.

SYNOPSIS

use DateTime::Format::Pg;

my $dt = DateTime::Format::Pg->parse_datetime( 2003-01-16 23:12:01 );

# 2003-01-16T23:12:01+0200
DateTime::Format::Pg->format_datetime($dt);

This module understands the formats used by PostgreSQL for its DATE, TIME, TIMESTAMP, and INTERVAL data types. It can be used to parse these formats in order to create DateTime or DateTime::Duration objects, and it can take a DateTime or DateTime::Duration object and produce a string representing it in a format accepted by PostgreSQL.

CONSTRUCTORS

The following methods can be used to create DateTime::Format::Pg objects.
new( name => value, ... )

Creates a new DateTime::Format::Pg instance. This is generally not required for simple operations. If you wish to use a different parsing style from the default then it is more comfortable to create an object.

my $parser = DateTime::Format::Pg->new()
my $copy = $parser->new( european => 1 );

This method accepts the following options:

european

If european is set to non-zero, dates are assumed to be in european dd/mm/yyyy format. The default is to assume US mm/dd/yyyy format (because this is the default for PostgreSQL).

This option only has an effect if PostgreSQL is set to output dates in the PostgreSQL (DATE only) and SQL (DATE and TIMESTAMP) styles.
Note that you dont have to set this option if the PostgreSQL server has been set to use the ISO format, which is the default.

server_tz

This option can be set to a DateTime::TimeZone object or a string that contains a time zone name.

This value must be set to the same value as the PostgreSQL servers time zone in order to parse TIMESTAMP WITH TIMEZONE values in the PostgreSQL, SQL, and German formats correctly.

Note that you dont have to set this option if the PostgreSQL server has been set to use the ISO format, which is the default.

clone()

This method is provided for those who prefer to explicitly clone via a method called clone().

my $clone = $original->clone();

If called as a class method it will die.

Time::Format is a Perl module for easy-to-use date/time formatting.

SYNOPSIS

use Time::Format qw(%time %strftime %manip);

$time{$format}
$time{$format, $unixtime}

print "Today is $time{yyyy/mm/dd}n";
print "Yesterday was $time{yyyy/mm/dd, time-24*60*60}n";
print "The time is $time{hh:mm:ss}n";
print "Another time is $time{H:mm am tz, $another_time}n";
print "Timestamp: $time{yyyymmdd.hhmmss.mmm}n";
%time also accepts Date::Manip strings and DateTime objects:
$dm = Date::Manip::ParseDate(last monday);
print "Last monday was $time{Month d, yyyy, $dm}";
$dt = DateTime->new (....);
print "Heres another date: $time{m/d/yy, $dt}";
It also accepts most ISO-8601 date/time strings:
$t = 2005/10/31T17:11:09; # date separator: / or - or .
$t = 2005-10-31 17.11.09; # in-between separator: T or _ or space
$t = 20051031_171109; # time separator: : or .
$t = 20051031171109; # separators may be omitted
$t = 2005/10/31; # date-only is okay
$t = 17:11:09; # time-only is okay
# But not:
$t = 20051031; # date-only without separators
$t = 171109; # time-only without separators
# ...because those look like epoch time numbers.
%strftime works like POSIXs strftime, if you like those %-formats.
$strftime{$format}
$strftime{$format, $unixtime}
$strftime{$format, $sec,$min,$hour, $mday,$mon,$year, $wday,$yday,$isdst}

print "POSIXish: $strftime{%A, %B %d, %Y, 0,0,0,12,11,95,2}n";
print "POSIXish: $strftime{%A, %B %d, %Y, 1054866251}n";
print "POSIXish: $strftime{%A, %B %d, %Y}n"; # current time
%manip works like Date::Manips UnixDate function.
$manip{$format};
$manip{$format, $when};

print "Date::Manip: $manip{%m/%d/%Y}n"; # current time
print "Date::Manip: $manip{%m/%d/%Y,last Tuesday}n";
These can also be used as standalone functions:
use Time::Format qw(time_format time_strftime time_manip);

print "Today is ", time_format(yyyy/mm/dd, $some_time), "n";
print "POSIXish: ", time_strftime(%A %B %d, %Y,$some_time), "n";
print "Date::Manip: ", time_manip(%m/%d/%Y,$some_time), "n";

This module creates global pseudovariables which format dates and times, according to formatting codes you pass to them in strings.

The %time formatting codes are designed to be easy to remember and use, and to take up just as many characters as the output time value whenever possible. For example, the four-digit year code is "yyyy", the three-letter month abbreviation is "Mon".

The nice thing about having a variable-like interface instead of function calls is that the values can be used inside of strings (as well as outside of strings in ordinary expressions). Dates are frequently used within strings (log messages, output, data records, etc.), so having the ability to interpolate them directly is handy.

Perl allows arbitrary expressions within curly braces of a hash, even when that hash is being interpolated into a string. This allows you to do computations on the fly while formatting times and inserting them into strings. See the "yesterday" example above.

The format strings are designed with programmers in mind. What do you need most frequently? 4-digit year, month, day, 24-based hour, minute, second -- usually with leading zeroes. These six are the easiest formats to use and remember in Time::Format: yyyy, mm, dd, hh, mm, ss. Variants on these formats follow a simple and consistent formula. This module is for everyone who is weary of trying to remember strftime(3)s arcane codes, or of endlessly writing $t[4]++; $t[5]+=1900 as you manually format times or dates.

Note that mm (and related codes) are used both for months and minutes. This is a feature. %time resolves the ambiguity by examining other nearby formatting codes. If its in the context of a year or a day, "month" is assumed. If in the context of an hour or a second, "minute" is assumed.

The format strings are not meant to encompass every date/time need ever conceived. But how often do you need the day of the year (strftimes %j) or the week number (strftimes %W)?

For capabilities that %time does not provide, %strftime provides an interface to POSIXs strftime, and %manip provides an interface to the Date::Manip modules UnixDate function.

If the companion module Time::Format_XS is also installed, Time::Format will detect and use it. This will result in a significant speed increase for %time and time_format.

DateTime::Format::Roman is a Perl module with roman day numbering for DateTime objects.

SYNOPSIS

use DateTime::Format::Roman;

my $formatter = DateTime::Format::Roman->new(
pattern => %d %f %b %y );

my $dt = DateTime->new( year => 2003, month => 5, day => 28 );

$formatter->format_datetime($dt);
# 5 Kal Jun 2003

This module formats dates in the Roman style.

The Romans expressed their dates in relation to three fixed dates per month. For example: the Ides of March was the 15th of that month; 14 March was called "2 Ides", 13 March was called "3 Ides", etcetera. The days in the second half of the month were named after the first day of the next month, the "Kalends"; e.g. 16 March was called "17 Kalends of April".

METHODS

new( pattern => $string )

Creates a new formatter object. The optional formatting pattern defines the format of the output of format_datetime(). If no formatting pattern is given, a reasonable default is used.

format_datetime($datetime)

Retruns the formatted string. This method can be called on a formatter object (created by new()), or it can be called as a class method. In the latter case, the default pattern is used.

PATTERN SPECIFIERS

The following specifiers are allowed in the format strings given to the new() method:

%b

The abbreviated month name.

%B

The full month name.

%d

The day of the month as a decimal number (including 1 for the fixed days).

%D

The day of the month, written as a number plus the corresponding fixed day.

%f

The fixed day part of the date.

%m

The month as a decimal number (range 1 to 12).

%y

The year as a decimal number.

If a specifier is preceded by O or o, numbers will be written in uppercase and lowercase Roman numerals, respectively.

The %f specifier accepts an additional argument of 1 digit, specifying the length of the output:

%0f : abbreviated name (e.g. "Kal")
%1f : full name (e.g. "Kalends")
%2f : one-letter abbreviation (e.g. "K")

Audio Format Converter is a an Amarok script that allows you to convert the audio format of the tracks in the playlist. The script takes a snapshot of the current playlist. Once the conversion has started, you can go back to using amaroK normally.

Supported files for both input and output include .flac, .ogg, .mp3, .mpc, .m4a, and .wav. Additionally, .wma, .ra, and are supported for input. (See below for the required packages.)

I dont know how to do anything with metatags from .wma or .ra. All I know is tags will get transferred to the output file if and only if the tags show up in the amaroK playlist. If they arent there, I suggest converting the files, then using a real tag editor like Easy Tag to put them in to the converted files.

This has only been tested on amaroK 1.2.4, but it should work on any amaroK>=1.2

The original files are NOT deleted. If the output file will overwrite an existing file, a dialog will appear to ask you whether to go ahead and overwrite or to skip the track. If you try to convert a file into the format its already in, a dialog will ask you how to handle this situation.

Depending on the number of tracks and the speed of your computer, this can take a long time to run. With each track, a passive popup will let you know what track its processing. At any time, you can stop the script by clicking stop in the amaroK script GUI.

File::Format::RIFF is a Perl module to Resource Interchange File Format/RIFF files.

SYNOPSIS

use File::Format::RIFF;

open( IN, file ) or die "Could not open file: $!";
my ( $riff1 ) = File::Format::RIFF->read( *IN );
close( IN );
$riff1->dump;

my ( $riff2 ) = new File::Format::RIFF( TYPE );
foreach my $chunk ( $riff1->data )
{
next if ( $chunk->id eq LIST );
$riff2->addChunk( $chunk->id, $chunk->data );
}
open( OUT, ">otherfile" ) or die "Could not open file: $!";
$riff2->write( *OUT );
close( OUT );

File::Format::RIFF provides an implementation of the Resource Interchange File Format. You can read, manipulate, and write RIFF files.

CONSTRUCTORS

$riff = new File::Format::RIFF( $type, $data );

Creates a new File::Format::RIFF object. $type is a four character code that identifies the type of this particular RIFF file. Certain types are defined to have a format, specifying which chunks must appear (e.g., WAVE files). If $type is not specified, it defaults to (four spaces). $data must be an array reference containing some number of RIFF lists and/or RIFF chunks. If $data is undef or not specified, then the new RIFF object is initialized empty.

$riff = File::Format::RIFF->read( $fh, $filesize );

Reads and parses an existing RIFF file from the given filehandle $fh. An exception will be thrown if the file is not a valid RIFF file. $filesize controls one aspect of the file format checking -- if $filesize is not specified, then stat will be called on $fh to determine how much data to expect. You may explicitly specify how much data to expect by passing in that value as $filesize. In either case, the amount of data read will be checked to make sure it matches the amount expected. Otherwise, it will throw an exception. If you do not wish it to make this check, pass in undef for $filesize.

Please note, if you wish to read an "in memory" filehandle, such as by doing this: open( $fh, read( $fh, $filesize );

The read constructor may also be used as a method. If used in this manner, then all existing data contained in $riff will be discarded, and replaced by the contents read from $fh.

$riff->write( $fh );

Outputs a properly-formatted RIFF file to the given filehandle $fh.

DateTime::Format::Excel is a Perl module that can convert between DateTime and Excel dates.

SYNOPSIS

use DateTime::Format::Excel;

# From Excel via class method:

my $datetime = DateTime::Format::Excel->parse_datetime( 37680 );
print $datetime->ymd(.); # 2003.02.28

# or via an object

my $excel = DateTime::Format::Excel->new();
print $excel->parse_datetime( 25569 )->ymd; # 1970-01-01

# Back to Excel number:

use DateTime;
my $dt = DateTime->new( year => 1979, month => 7, day => 16 );
my $daynum = DateTime::Format::Excel->format_datetime( $dt );
print $daynum; # 29052

# or via an object
my $other_daynum = $excel->format_datetime( $dt );
print $other_daynum; # 29052

Excel uses a different system for its dates than most Unix programs. This module allows you to convert between a few of the Excel raw formats and DateTime objects, which can then be further converted via any of the other DateTime::Format::* modules, or just with DateTimes methods.

If you happen to be dealing with dates between 1 Jan 1900 and 1 Mar 1900 please read the notes on epochs.

If youre wanting to handle actual spreadsheet files, you may find Spreadsheet::WriteExcel and Spreadsheet::ParseExcel of use.
