DocSet::Doc::POD2HTMLPS - POD source to PS (intermediate HTML) target converter
DocSet::Doc sub-class which converts a source document in POD,
into an output document in PS (intermediate in HTML).
For the rest of the super class methods see
documents using this class are rendered via
which is a subclass of
Since we want the final PDF document which potentially includes many chapters in it to look more as a book and have a nice Table of Contents,
we need to change the default structure of
=head1 NAME becomes a title of the chapter and removed from the POD source,
therefore we need to bump up all the remaining
=headX headers by one.
=head1 is rendered as
Therefore we override the super class's methods
In addition we put <a name> anchors next to the headers so the PDF document can be hyperlinked if the reader supports this feature.
view_seq_file() is overriden too. Here we search for the file relative to the location of the document and if we find it we include its contents since the PDFs are created for making dead tree copies and therefore linking is not an option. Notice that it's OK to say F</etc/passwd> since it won't be found unless you actually put it under the current documents path or put the source document in the / path.
view_verbatim() is overriden: renders the <pre>...</pre> html,
but defines a CSS class
pre-section so the look-n-feel can be adjusted.
in addition it splits text into 40 lines chunks.
This solves two problems:
html2pstries to fit the whole <pre>...</pre> in a single page ending up using a very small unreadable font when the text is long.
ps2pdffails to convert ps to pdf if the former includes <pre>...</pre>, longer than 40 lines in one chunk.
The following rendering methods: anchor() and view_seq_link_transform_path() are defined in the
DocSet::Doc::Common class and documented there.
