- =head1 NAME
-
- Pod::Simple::HTMLBatch - convert several Pod files to several HTML files
-
- =head1 SYNOPSIS
-
- perl -MPod::Simple::HTMLBatch -e 'Pod::Simple::HTMLBatch::go' in out
-
-
- =head1 DESCRIPTION
-
- This module is used for running batch-conversions of a lot of HTML
- documents
-
- This class is NOT a subclass of Pod::Simple::HTML
- (nor of bad old Pod::Html) -- although it uses
- Pod::Simple::HTML for doing the conversion of each document.
-
- The normal use of this class is like so:
-
- use Pod::Simple::HTMLBatch;
- my $batchconv = Pod::Simple::HTMLBatch->new;
- $batchconv->some_option( some_value );
- $batchconv->some_other_option( some_other_value );
- $batchconv->batch_convert( \@search_dirs, $output_dir );
-
- =head2 FROM THE COMMAND LINE
-
- Note that this class also provides
- (but does not export) the function Pod::Simple::HTMLBatch::go.
- This is basically just a shortcut for C<<
- Pod::Simple::HTMLBatch->batch_convert(@ARGV) >>.
- It's meant to be handy for calling from the command line.
-
- However, the shortcut requires that you specify exactly two command-line
- arguments, C<indirs> and C<outdir>.
-
- Example:
-
- % mkdir out_html
- % perl -MPod::Simple::HTMLBatch -e Pod::Simple::HTMLBatch::go @INC out_html
- (to convert the pod from Perl's @INC
- files under the directory ../htmlversion)
-
- (Note that the command line there contains a literal atsign-I-N-C. This
- is handled as a special case by batch_convert, in order to save you having
- to enter the odd-looking "" as the first command-line parameter when you
- mean "just use whatever's in @INC".)
-
- Example:
-
- % mkdir ../seekrut
- % chmod og-rx ../seekrut
- % perl -MPod::Simple::HTMLBatch -e Pod::Simple::HTMLBatch::go . ../htmlversion
- (to convert the pod under the current dir into HTML
- files under the directory ../htmlversion)
-
- Example:
-
- % perl -MPod::Simple::HTMLBatch -e Pod::Simple::HTMLBatch::go happydocs .
- (to convert all pod from happydocs into the current directory)
-
-
-
- =head1 MAIN METHODS
-
- =over
-
- =item $batchconv = Pod::Simple::HTMLBatch->new;
-
- This TODO
-
-
- =item $batchconv->batch_convert( I<indirs>, I<outdir> );
-
- this TODO
-
- =item $batchconv->batch_convert( undef , ...);
-
- =item $batchconv->batch_convert( q{@INC}, ...);
-
- These two values for I<indirs> specify that the normal Perl @INC
-
- =item $batchconv->batch_convert( \@dirs , ...);
-
- This specifies that the input directories are the items in
- the arrayref C<\@dirs>.
-
- =item $batchconv->batch_convert( "somedir" , ...);
-
- This specifies that the director "somedir" is the input.
- (This can be an absolute or relative path, it doesn't matter.)
-
- A common value you might want would be just "." for the current
- directory:
-
- $batchconv->batch_convert( "." , ...);
-
-
- =item $batchconv->batch_convert( 'somedir:someother:also' , ...);
-
- This specifies that you want the dirs "somedir", "somother", and "also"
- scanned, just as if you'd passed the arrayref
- C<[qw( somedir someother also)]>. Note that a ":"-separator is normal
- under Unix, but Under MSWin, you'll need C<'somedir;someother;also'>
- instead, since the pathsep on MSWin is ";" instead of ":". (And
- I<that> is because ":" often comes up in paths, like
- C<"c:/perl/lib">.)
-
- (Exactly what separator character should be used, is gotten from
- C<$Config::Config{'path_sep'}>, via the L<Config> module.)
-
- =item $batchconv->batch_convert( ... , undef );
-
- This specifies that you want the HTML output to go into the current
- directory.
-
- (Note that a missing or undefined value means a different thing in
- the first slot than in the second. That's so that C<batch_convert()>
- with no arguments (or undef arguments) means "go from @INC, into
- the current directory.)
-
- =item $batchconv->batch_convert( ... , 'somedir' );
-
- This specifies that you want the HTML output to go into the
- directory 'somedir'.
- (This can be an absolute or relative path, it doesn't matter.)
-
- =back
-
-
- Note that you can also call C<batch_convert> as a class method,
- like so:
-
- Pod::Simple::HTMLBatch->batch_convert( ... );
-
- That is just short for this:
-
- Pod::Simple::HTMLBatch-> new-> batch_convert(...);
-
- That is, it runs a conversion with default options, for
- whatever inputdirs and output dir you specify.
-
-
- =head2 ACCESSOR METHODS
-
- The following are all accessor methods -- that is, they don't do anything
- on their own, but just alter the contents of the conversion object,
- which comprises the options for this particular batch conversion.
-
- We show the "put" form of the accessors below (i.e., the syntax you use
- for setting the accessor to a specific value). But you can also
- call each method with no parameters to get its current value. For
- example, C<< $self->contents_file() >> returns the current value of
- the contents_file attribute.
-
- =over
-
-
- =item $batchconv->verbose( I<nonnegative_integer> );
-
- This controls how verbose to be during batch conversion, as far as
- notes to STDOUT (or whatever is C<select>'d) about how the conversion
- is going. If 0, no progress information is printed.
- If 1 (the default value), some progress information is printed.
- Higher values print more information.
-
-
- =item $batchconv->index( I<true-or-false> );
-
- This controls whether or not each HTML page is liable to have a little
- table of contents at the top (which we call an "index" for historical
- reasons). This is true by default.
-
-
- =item $batchconv->contents_file( I<filename> );
-
- If set, should be the name of a file (in the output directory)
- to write the HTML index to. The default value is "index.html".
- If you set this to a false value, no contents file will be written.
-
- =item $batchconv->contents_page_start( I<HTML_string> );
-
- This specifies what string should be put at the beginning of
- the contents page.
- The default is a string more or less like this:
-
- <html>
- <head><title>Perl Documentation</title></head>
- <body class='contentspage'>
- <h1>Perl Documentation</h1>
-
- =item $batchconv->contents_page_end( I<HTML_string> );
-
- This specifies what string should be put at the end of the contents page.
- The default is a string more or less like this:
-
- <p class='contentsfooty'>Generated by
- Pod::Simple::HTMLBatch v3.01 under Perl v5.008
- <br >At Fri May 14 22:26:42 2004 GMT,
- which is Fri May 14 14:26:42 2004 local time.</p>
-
-
-
- =item $batchconv->add_css( $url );
-
- TODO
-
- =item $batchconv->add_javascript( $url );
-
- TODO
-
- =item $batchconv->css_flurry( I<true-or-false> );
-
- If true (the default value), we autogenerate some CSS files in the
- output directory, and set our HTML files to use those.
- TODO: continue
-
- =item $batchconv->javascript_flurry( I<true-or-false> );
-
- If true (the default value), we autogenerate a JavaScript in the
- output directory, and set our HTML files to use it. Currently,
- the JavaScript is used only to get the browser to remember what
- stylesheet it prefers.
- TODO: continue
-
- =item $batchconv->no_contents_links( I<true-or-false> );
-
- TODO
-
- =item $batchconv->html_render_class( I<classname> );
-
- This sets what class is used for rendering the files.
- The default is "Pod::Simple::Search". If you set it to something else,
- it should probably be a subclass of Pod::Simple::Search, and you should
- C<require> or C<use> that class so that's it's loaded before
- Pod::Simple::HTMLBatch tries loading it.
-
- =back
-
-
-
-
- =head1 NOTES ON CUSTOMIZATION
-
- TODO
-
- call add_css($someurl) to add stylesheet as alternate
- call add_css($someurl,1) to add as primary stylesheet
-
- call add_javascript
-
- subclass Pod::Simple::HTML and set $batchconv->html_render_class to
- that classname
- and maybe override
- $page->batch_mode_page_object_init($self, $module, $infile, $outfile, $depth)
- or maybe override
- $batchconv->batch_mode_page_object_init($page, $module, $infile, $outfile, $depth)
-
-
-
- =head1 ASK ME!
-
- If you want to do some kind of big pod-to-HTML version with some
- particular kind of option that you don't see how to achieve using this
- module, email me (C<sburke@cpan.org>) and I'll probably have a good idea
- how to do it. For reasons of concision and energetic laziness, some
- methods and options in this module (and the dozen modules it depends on)
- are undocumented; but one of those undocumented bits might be just what
- you're looking for.
