Doc: Include full LinuxDocTools code

Browse source 
BIRD uses hacked LinuxDocTools for building documentation, keeping some
parts locally and using remaining parts from system-installed one. This
setup breaks when LinuxDocTools makes some internal changes and is hard
to keep consistent.

Just include full LinuxDocTools code (both hacked and unmodified parts)
to avoid consistency issues. Note that we still need some binaries from
LinuxDocTools, so it still needs to be installed to build documentation.

=head1 NAME
LinuxDocTools - SGML conversion utilities for LinuxDoc DTD.
=head1 SYNOPSIS
use LinuxDocTools;
LinuxDocTools::init;
@files = LinuxDocTools::process_options ($0, @ARGV);
for $curfile (@files) {
LinuxDocTools::process_file ($curfile);
}
=head1 DESCRIPTION
The LinuxDocTools package encapsulates all the functionality offered by
LinuxDoc-Tools. It is used, of course, by LinuxDoc-Tools;
but the encapsulation should provide for a simple interface for other users as well.

=item LinuxDocTools::init
Takes care of initialization of package-global variables (which are actually
defined in L<LinuxDocTools::Vars>). The package-global variables are I<$global>,
a reference to a hash containing numerous settings, I<%Formats>, a hash
containing all the formats, and I<%FmtList>, a hash containing the currently
active formats for help texts.
Apart from this, C<LinuxDocTools::init> also finds all distributed and site-local
formatting backends and C<require>s them.

This function contains all initialization that is bound to the current
invocation of LinuxDocTools. It looks in C<$0> to deduce the backend that
should be used (ld2txt activates the I<txt> backend) and parses the
options array. It returns an array of filenames it encountered during
option processing.
As a side effect, the environment variables I<SGMLDECL> and
I<SGML_CATALOG_FILES> are modified.

=item LinuxDocTools::process_file
With all the configuration done, this routine will take a single filename
and convert it to the currently active backend format. The conversion is
done in a number of steps in tight interaction with the currently active
backend (see also L<LinuxDocTools::BackEnd>):
=over
=item 1. Backend: set NSGMLS options and optionally create a pre-NSGMLS pipe.
=item 2. Here: Run the preprocessor to handle conditionals.
=item 3. Here: Run NSGMLS.
=item 4. Backend: run pre-ASP conversion.
=item 5. Here: Run SGMLSASP.
=item 6. Backend: run post-ASP conversion, generating the output.
=back
All stages are influenced by command-line settings, currently active format,
etcetera. See the code for details.

=head1 DESCRIPTION
The LinuxDocTools package encapsulates all the functionality offered by
LinuxDoc-Tools. It is used, of course, by LinuxDoc-Tools;
but the encapsulation should provide for a simple interface for other users as well.

Takes care of initialization of package-global variables (which are actually
defined in L<LinuxDocTools::Vars>). The package-global variables are I<$global>,
a reference to a hash containing numerous settings, I<%Formats>, a hash
containing all the formats, and I<%FmtList>, a hash containing the currently
active formats for help texts.
Apart from this, C<LinuxDocTools::init> also finds all distributed and site-local
formatting backends and C<require>s them.

=item LinuxDocTools::process_file
With all the configuration done, this routine will take a single filename
and convert it to the currently active backend format. The conversion is
done in a number of steps in tight interaction with the currently active
backend (see also L<LinuxDocTools::BackEnd>):
=over
=item 1. Backend: set NSGMLS options and optionally create a pre-NSGMLS pipe.
=item 2. Here: Run the preprocessor to handle conditionals.
=item 3. Here: Run NSGMLS.
=item 4. Backend: run pre-ASP conversion.
=item 5. Here: Run SGMLSASP.
=item 6. Backend: run post-ASP conversion, generating the output.
=back
All stages are influenced by command-line settings, currently active format,
etcetera. See the code for details.

LinuxDoc-Tools backend modules need to conform to a certain interface which is
detailed in this document. The interface makes sure that new backend modules
(or customer overrides) are compatible with what the main B<LinuxDocTools>
package expects. Note that this interface is still subject to change, you
should check this document on new releases of LinuxDoc-Tools.
=head1 INTERFACE
The interface between the main package and individual backends is very
minimal - only one global variable is modified, everything else is local. It
relies heavily on references and complex datatypes, so you want to make
sure that you're up-to-date with Perl5.
Every backend creates a reference to a hash and stores this reference in
the global I<%Formats> hash:
my $BackEnd = {};
$Formats{"BackEnd"} = $BackEnd;
The rest of this document will deal with the entries in the local hash
referenced by I<$BackEnd>.
=head1 HASH ENTRIES
=over 4
=item NAME
Specify the name of the backend, for help messages etcetera.
$BackEnd->{NAME} = "BackEnd";
=item HELP
Specify an optional extra help message printed when the default usage
function is executed (see L<LinuxDocTools::Utils>).
$BackEnd->{HELP} = "This is just and example message";
=item OPTIONS
This specifies the local set of options, which is added to the global set
of options (available in I<$global>). The options are specified as an
array of hashes containing a number of keys:
=over 4
=item option
The long option name
=item type
The type of the option, one of B<f> (flag), B<l> (list of allowed values),
B<s> (string), or B<i> (integer).
=item values
An array of allowed values, in case the option is of the list type.
=item short
A short (single-letter) version of the option name.
=back
Options can be specified as long options:
--papersize=a4
or as short options:
-p a4
Note that both the long options as the short options must not conflict with
the global options (an override is not - yet - possible) and should not
conflict with other backends.
$BackEnd->{OPTIONS} = [
{ option => "split", type => "l",
'values' => [ "0", "1", "2" ], short => "s" },
{ option => "dosnames", type => "f", short => "D" },
{ option => "imagebuttons", type => "f", short => "I"}
];
The long names themselves function as hash keys; a default can be given
here and the option processing function will store any values found
at the same place:
$BackEnd->{'split'} = 1;
$BackEnd->{dosnames} = 0;
$BackEnd->{imagebuttons} = 0;
=item preNSGMLS
If defined, this should contain a subroutine that normally does two things: it
can modify the global value C<$global-E<gt>{NsgmlsOpts}> and it can set the
global value C<$global-E<gt>{NsgmlsPrePipe}>. The first variable contains
the option string passed to B<nsgmls>, and the second variable can contain
a command that generates the input for B<nsgmls>, presumably using the
current input file in some way (the current input file can be found
in C<$global-E<gt>{file}>).
$BackEnd->{preNSGMLS} = sub {
$global->{NsgmlsOpts} .= " -ifmtBackEnd ";
$global->{NsgmlsPrePipe} = "sed 's/\@/\@\@/g' $global->{file}";
};
=item preASP
If defined, this should contain a subroutine accepting an input and an output
file descriptor. The input file descriptor contains the raw output from
B<nsgmls>, and the output file descriptor should be filled with input
to B<sgmlsasp>. This stage is often used to munch character entities
before they're fed to B<sgmlsasp>, see L<LinuxDocTools::CharEnts>. If the routine
doesn't return C<0>, LinuxDocTools aborts.
$BackEnd->{preASP} = sub
{
my ($infile, $outfile) = @_;
while (<$infile>)
{
s/([^\\])\\n/$1 \\n/g;
print $outfile $_;
}
return 0;
};
=item postASP
This entry should always be defined, because it needs to contain a routine
that receives the output from B<sgmlsasp> which normally needs finalization.
LinuxDocTools itself doesn't know about file-naming conventions, etcetera, of
the backend so writing the final file is left to the backend. The subroutine
receives a reference to a filehandle (containing B<sgmlsasp> output) and
should do whatever it likes with this datastream.
$BackEnd->{postASP} = sub
{
my $infile = shift;
copy ($infile, "$global->{filename}.ext");
return 0;
};

LinuxDocTools::CharEnts - Interface to Text::EntityMap
=head1 SYNOPSIS
my $char_maps = load_char_maps ('.2ext', [ Text::EntityMap::sdata_dirs() ]);
$value = parse_data ($value, $char_maps, $escape_sub);
=head1 DESCRIPTION
This module provides a simple interface to the entity map handling provided by
B<Text::EntityMap>.
=head1 FUNCTIONS
=over 4
=cut
use Text::EntityMap;
use Exporter;
use vars qw(@ISA @EXPORT $VERSION);
@ISA = qw(Exporter);

# `%warn_map' tracks entities that were not able to be mapped so they
# are only warned once.
my %warn_map = ();
=item parse_data ($data, $char_map, $escape_sub)
B<parse_data> takes a string of I<$data> in the output format of
B<nsgmls> (see SP's C<sgmlsout.htm> document) without the leading dash.
B<parse_data> calls I<$char_map>'s lookup method for each sdata
entity reference. If the entity reference is undefined, it is
left alone (without the (n)sgmls C<\|>). For all remaining data,
B<parse_data> calls back into I<$escape_sub> to properly escape
characters for the backend formatter. Strings returned from the
lookup method are assumed to be already escaped.
This routine is derived from David Megginson's SGMLSpm.

B<LinuxDocTools::Lang> gives a simple interface to various forms of language
names, and provides a translation service. Languages can be specified in
three different ways: by their native name, by their english name, and
by their 2-letter ISO code. For example, you can specify the German
language as C<deutsch>, as C<german> or as C<de>.

=head1 NAME
Text::EntityMap - map character entities to output formats
=head1 SYNOPSIS
use Text::EntityMap;
$tex_iso_lat1 = Text::EntityMap->load ("ISOlat1.2tex");
$tex_iso_lat2 = Text::EntityMap->load ("ISOlat2.2tex");
$ent_group = Text::EntityMap->group ($tex_iso_lat1, $tex_iso_lat2);
$ent_group->lookup ('[copy ]');
@dirs = Text::EntityMap->sdata_dirs ();
=head1 DESCRIPTION
Text::EntityMap is a module that can look-up an output-format
equivalent for special character or other entities. This was inspired
by SGML character entities but can be used in any scenario where
output formatting codes are different for special characters.
The C<load()> function takes a file name of a mapping table and
returns an Text::EntityMap object.
The C<group()> function takes a ordered list of Text::EntityMap and
returns an Text::EntityMapGroup object. Looking up entities in a
group object returns the entity replacement returned by the first
EntityMap object. This can be used both to group sets of mapping
files into one object as well as overriding entity replacements. A
EntityMapGroup may contain other EntityMapGroup's.
The C<lookup()> function can be used with either a EntityMap or
EntityMapGroup object. It takes an entity name and returns the
output-format equivalent.
C<sdata_dirs()> returns an array containing the local site directory
and ``this'' version of EntityMap's installed directory that contain
the entity maps. Callers can use these paths when looking for tables
to pass to C<load()>.

This is `linuxdoc-tools', a series of tools to implement the Linux
Documentation Project HOWTO and book styles in SGML.
This copy was modified in order to work with birddoc DTD. It is
based on version 0.9.73-2 from Debian 10.
----------------------------------
The linuxdoc-tools license
----------------------------------
linuxdoc-tools is derived from linuxdoc-SGML, originally written by
Matt Welsh and later maintained by Cees de Groot. Linuxdoc-SGML is
based on James Clark's sgmls parser, and the QWERTZ DTD by Tom
Gordon. Magnus Alvestad provided the current HTML support. For
the rest of linuxdoc-SGML,
Copyright (C) 1994-1996 Matt Welsh <mdw@cs.cornell.edu>
Copyright (C) 1996-1998 Cees de Groot <cg@pobox.com>
Original Linuxdoc-SGML itself does not have any limitations.
Everything not having explicit additional conditions can be freely
used, modified, and redistributed, under the usual fair use clauses:
* No warranty. Use at your own risk.
* Do not pretend to have written what you did not (Preserve credits
and Copyright notices of the different elements if present).
Since then, lots of smaller and bigger changes resulted in a rename
to SGML-Tools (and then to SGMLtools, the hyphen caused confusion)
to indicate that it wasn't just for Linux anymore. See files
CHANGES.old-v1 and CONTRIBUTORS.old-v1 for changelog and list of
contributors to old linuxdoc-sgml and sgmltools-v1.
When sgml-tools dropped support for the linuxdoc DTD, Taketoshi Sano
<sano@debian.org> forked the code to linuxdoc-tools. See README file.
