NAME

Palm::PalmDoc - Perl extension for PalmDoc format

SYNOPSIS

# Example 1
use Palm::PalmDoc;
my $doc = Palm::PalmDoc->new({INFILE=>"foo.txt",OUTFILE=>"foo.pdb",TITLE=>"foo bar",COMPRESS=>1});
$doc->read_text();
$doc->write_text();

# Example 2
use Palm::PalmDoc;
my $doc = Palm::PalmDoc->new({OUTFILE=>"foo.pdb",TITLE=>"foo bar"});
$doc->compression(1);
$doc->body("Foo Bar"x100);
$doc->write_text();

# Example 3
use Palm::PalmDoc;
my $doc = Palm::PalmDoc->new(INFILE=>"README");
$doc->compression(1); #Compression is off by default
$doc->read_text();
open(F,">readme.pdb") || die $!;
print F $doc->pdb_header,$doc->body;
close(F);

# Example 4
use Palm::PalmDoc;
my $doc = Palm::PalmDoc->new();
$doc->parse_from_file("README");
open(F,">readme.pdb") || die $!;
$doc->parse_from_filehandle("",\*F);
$doc->compression(1); #Compression is off by default
$doc->read_text();
$doc->write_text();

DESCRIPTION

This module can format ASCII text into a PalmDoc PDB file.

Palm::PalmDoc provides the following functions :

new(@params)

The constructor of Palm::PalmDoc. This function can accept parameters used to generate the PalmDoc file. Parameters accepted are INFILE, OUTFILE, TITLE and BODY. They need to be passed in hash context (or a list/array mimicking a hash). A reference to a hash is also accepted, as well as a reference to an array.

my $doc = Palm::PalmDoc->new({INFILE=>"foo.txt",OUTFILE=>"foo.pdb"});

is same as

my $doc = Palm::PalmDoc->new(INFILE=>"foo.txt",OUTFILE=>"foo.pdb");

or as

my $doc = Palm::PalmDoc->new("INFILE","foo.txt","OUTFILE","foo.pdb");

Keys are always uppercased (even though they may not be passed as such). Possible keys are:

INFILE
The input filename
OUTFILE
The output filename
TITLE
The document title
BODY
The document body
COMPRESS
Boolean to indicate compression
IGNORENL
Boolean to indicate to ingoring newlines.
body($body)

This is a plain getter/setter function except that it also sets the required length. The same action can be performed by setting the appropriate hash key/value pair in the constructor or by using the read_text function.

$doc->body("Foo Bar"x100);
title($title)

This is a plain getter/setter function for the title. The same action can be performed by setting the appropriate hash key/value pair in the constructor.

$doc->title("Foo Bar Baz");
infile($filename)

This is a plain getter/setter function for the Input filename. The same action can be performed by setting the appropriate hash key/value pair in the constructor. If both an input file and an input filehandle are defined, the input file is used.

$doc->infile("foo.txt");
outfile($filename)

This is a plain getter/setter function for the Output filename. The same action can be performed by setting the appropriate hash key/value pair in the constructor. If both an output file and an output filehandle are defined, the output file is used.

$doc->outfile("foo.pdb");
parse_from_file($inputfile,$outputfile)

parse_from_file uses infile() and outfile() to set the filenames. If both an input file and an input filehandle are defined, the input file is used. Same applies for output file and output filehandle.

$doc->parse_from_file("foo.txt","foo.pdb");
parse_from_filehandle($inputfilehandle,$outputfilehandle)

parse_from_filehandle takes filehandle as arguments. When no input filehandle is defined STDIN is used. When no output filehandle is defined STDOUT is used. If both an input file and an input filehandle are defined, the input file is used. Same applies for output file and output filehandle.

$doc->parse_from_filehandle(\*FOO,\*BAR);
read_text()

This function uses the inputfile property to read the body from a file. It also sets the required length. This function returns the text read if successfull or a false if not successfull.

$doc->read_text();
write_text()

This function uses the outputfile property to write the header and body to a file. The headers are generated by the pdb_header function. This function returns true if successfull or false if not successfull.

$doc->write_text();
pdb_header()

This function generates the correct PDB headers for the body and length. You only need to use this function if you're writing the body to a file manually since write_text() already used pdb_header. This function returns the generated header which should precede the converted body. Writing to an already opened filehandle can be done with parse_from_filehandle too.

use Palm::PalmDoc;
my $doc = Palm::PalmDoc->new();
$doc->body("Foo Bar"x1000);
$doc->title("Foo Bar Baz");
open(FOO,">foo.pdb") || die $!;
print FOO $doc->pdb_header(),$doc->body();
close(FOO);
compression($boolean)

This function toggles the compression. By default compression is off. The same action can be performed by setting the appropriate hash key/value pair in the constructor.

$doc->compression(1); #Turn PalmDoc Compression on
ignorenl($boolean)

This function toggles the ignoring the newlines. By default newlines are not ignored. The same action can be performed by setting the appropriate hash key/value pair in the constructor. Credit for this functionality goes to Josef Moellers.

$doc->ignorenl(1); #Ignore newlines

THANK YOU!!!!

A HUGE thanks goes to Josef Moellers for fixing 2 BIG bugs in the code.

Thanks also to Scott Wiersdorf for adding warning cleanness.

Waves to Steve Swantz for pointing me to the typos in the POD and README.

John G. Smith for pointing out that titles can't be longer than 31 chars and providing fix for it.

TODO

Since my primary goal was to port the core, most of the features present in Bibelot are not included.
