=head1 NAME

TeXLive::TLPOBJ - TeX Live Package Object access module

=head1 SYNOPSIS

	use TeXLive::TLPOBJ;

	my $tlpobj = TeXLive::TLPOBJ->new( name => "foobar" );

=head1 DESCRIPTION

The L<TeXLive::TLPOBJ> module provide access to TeX Live Package Object
files describing a self-contained package.

=head1 FILE SPECIFICATION

Please see L<TeXLive::TLPSRC> documentation for the specification. The
only differences are that the various C<*pattern> keys are invalid, and
instead there are the respective C<*files> keys described below. Furthermore
some more I<keys> is allowed: C<revision> which specifies the maximum of 
all last changed revision of files contained in the package, and anything
starting with C<catalogue-> specifying information coming from the
TeX Catalogue.

All these keys have in common that they are followed by a list of files
B<intended> by one space. They differ only in the first line itself
(described below).

=over

=item C<srcfiles>, C<runfiles>
each of these three items contains in addition the sum of sizes of the
single files (currently in byte, but this may change).

	srcfiles size=NNNNNN
	runfiles size=NNNNNN

=item C<docfiles>
The docfiles line itself is similar to the C<srcfiles> and C<runfiles> lines
above:

	docfiles size=NNNNNN

But the lines listing the files are allowed to have additional tags:

	/------- excerpt from achemso.tlpobj
	|...
	|docfiles size=1702468
	| texmf-dist/doc/latex/aeguill/README details="Package Readme"
	| texmf-dist/doc/latex/achemso/achemso.pdf details="Package documentation" language="en"
	|...

Currently only the tags C<details> and C<language> are allowed.

=item C<runfiles>
Since C<runfiles> are different for the different architectures one C<tlpobj>
file can contain C<runfiles> lines for different architectures. The
architecture is specified on the C<binfiles> using the C<arch=XXX> tag. Thus,
C<binfiles> lines look like

	binfiles arch=XXXX size=NNNNN

=back

Thus a typical entry for runfiles looks like this:

	/------- excerpt from bin-dvips.tlpobj
	|...
	|runfiles size=1702468
	| texmf/dvips/base/color.pro
	| ...
	| texmf/scripts/pkfix/pkfix.pl
	|binfiles arch=i386-solaris size=329700
	| bin/i386-solaris/afm2tfm
	| bin/i386-solaris/dvips
	| bin/i386-solaris/pkfix
	|binfiles arch=win32 size=161280
	| bin/win32/afm2tfm.exe
	| bin/win32/dvips.exe
	| bin/win32/pkfix.exe
	|...

=head1 PACKAGE VARIABLES

TeXLive::TLPOBJ has one package wide variable which is C<zipdir> where
generated zip files are saved (if not otherwise specified.

	TeXLive::TLPOBJ->zipdir("path/to/zip/dir");

=head1 MEMBER ACCESS FUNCTIONS

For any of the I<keys> a function

	$tlpobj->key

is available, which returns the current value when called without an argument,
and sets the respective value when called with an argument. For the 
TeX Catalogue Data the function

	$tlpobj->cataloguedata

returns and takes as argument a hash.

Arguments and return values for C<name>, C<category>, C<shortdesc>,
C<longdesc>, C<catalogue>, C<revision> are single scalars.  Arguments
and return values for C<depends>, C<executes> are lists.  Arguments and
return values for C<docfiles>, C<runfiles>, C<srcfiles> are lists.
Arguments and return values for C<binfiles> is a hash with the
architectures as keys.

The size values are handled with these functions:

	$tlpobj->docsize
	$tlpobj->runsize
	$tlpobj->srcsize
	$tlpobj->binsize("arch1", ...)

which set or get the current value of the respective sizes. Note that also
the C<binsize> function returns (and takes as argument) a hash with the 
architectures as keys, similar to the C<runfiles> functions (see above).

=head1 OTHER FUNCTIONS

The following functions can be called for an C<TLPOBJ> object:

=over

=item C<new>
(constructor) returns a new C<TLPSRC> object. The arguments to the C<new>
constructor can be in the usual hash representation for the different keys
above:

	$tlpobj = TLPOBJ->new ( name => "foobar", shortdesc => "The foobar package" );

=item C<from_file("filename")>
reads a C<tlpobj> file.

	$tlpobj = new TLPOBJ;
	$tlpobj->from_file("path/to/the/tlpobj/file");

=item C<from_fh($filehandle [, $multi] )>
read the textual representation of a TLPOBJ from an already opened file handle.
If C<$multi> is undefined (ie not given) then multiple tlpobj in the
same file are treated as errors. If C<$multi> is defined then returns
after reading one tlpobj.

Returns 1 if it found a tlpobj, otherwise 0

=item C<writeout>
writes the textual representation of a C<TLPOBJ> object to stdout, or the
filehandle if given:

	$tlpsrc->writeout;
	$tlpsrc->writeout(\*FILEHANDLE);

=item C<writeout_simple>
debugging function for comparison with tpm/tlps, will go away.

=item C<make_zip($tltree[,$destdir[,$zipname]])>
creates a zip file of the arch B<independent> files in the TLPOBJ
in $destdir (if not defined then TLPOBJ->zipdir is used).
The file name of the created zipfile is $zipname (if not
present $tlpobj->name.zip)

If the package contains "binfiles"; then zip files for 
all archs containing B<only> the binfiles are created, and 
the zipfile name is C<$zipname.$arch.zip>

All the arch independent zip files B<also> contain the 
respective TLPOBJ file in 
	.tlpobj/$name.tlpobj
so C<$zipname.zip> does contain this tlpobj file, while
C<$zipname.$arch.zip> does NOT.

=item C<recompute_sizes ($tltree)>
recomputes the sizes based on the information present in C<$tltree>.

=item C<recompute_revision ($tltree)>
recomputes the revision based on the information present in C<$tltree>.

=item C<update_from_catalogue ($texcatalogue)>
adds information from a C<TeXCatalogue> object 
(currently license, version, url, and updates docfiles with details and
languages tags if present in the Catalogue)

=item C<is_arch_dependent>
returns 1 if there are C<binfiles>, otherwise 0.

=item C<total_size>
If no argument is given returns the sum of C<srcsize>, C<docsize>,
C<runsize>.

If arguments are given, they are assumed to be architecture names, and
it returns the above plus the sum of sizes of C<binsize> for those
architectures.

=item C<{add,remove}_{src,run,doc}files ( @files )>
adds or removes files to the respective list of files

=item C<{add,remove}_binfiles ($arch, @files)>
adds or removes files from the list of C<binfiles> for the given architecture

=item C<{add,remove}_files ($type, $files)>
adds or removes files for the given type (only for C<run>, C<src>, C<doc>).

=item C<all_files>
returns a list of all files of all types.
