DEPENDENCIES

o "P5-Palm"
CONSTRUCTOR
- "new()"
- Instantiates a new Ebook::Tools::EReader object.
ACCESSOR METHODS
- "filebase"
- In scalar context, this is the basename of the object attribute
"filename". In list context, it actually returns the basename,
directory, and extension as per "fileparse" from File::Basename. - "footnotes()"
- Returns a hash containing all of the footnotes found in the file, where the keys are the footnote ids and the values contain the footnote text.
- "footnotes_pml()"
- Returns a string containing all of the footnotes in a form suitable to
append to the end of PML text output. This is called as part of
"pml()". - "footnotes_html()"
- Returns a string containing all of the footnotes in a form suitable to
append to the end of HTML text output. This is called as part of
"html()". - "pml()"
- Returns a string containing the entire original document text in its
original encoding, including all sidebars and footnotes. - "html()"
- Returns a string containing the entire document text (including all
sidebars and footnotes) converted to HTML. - Note that the PML text is stored in the object (and thus retrieving it
is very fast), but generating the HTML output requires that the text be
converted every time this method is used, consuming extra processing
time. - "sidebars()"
- Returns a hash containing all of the sidebars found in the file, where the keys are the sidebar ids and the values contain the sidebar text.
- "sidebars_pml()"
- Returns a string containing all of the sidebars in a form suitable to
append to the end of PML text output. This is called as part of
"pml()". - "sidebars_html()"
- Returns a string containing all of the sidebars in a form suitable to
append to the end of HTML text output. This is called as part of
"html()". - "write_html($filename)"
- Writes the raw book text to disk in PML form (including all sidebars
and footnotes) with the given filename. - If $filename is not specified, writes to "$self-"filebase> with a
".html" extension. - Returns the filename used on success, or undef if there was no text to write.
- "write_images()"
- Writes each image record to the disk.
- Returns a list containing the filenames of all images written, or undef if none were found.
- "write_pml($filename)"
- Writes the raw book text to disk in PML form (including all sidebars
and footnotes) with the given filename. - If $filename is not specified, writes to "$self-"filebase> with a
".pml" extension. - Returns the filename used on success, or undef if there was no text to write.
- "write_unknown_records()"
- Writes each unidentified record to disk with a filename in the format
of 'raw-record-####', where #### is the record number (not the record
ID). - Returns the number of records written.
MODIFIER METHODS
- "Load($filename)"
- Sets "$self-"{filename}> and then loads and parses the file specified
by $filename, calling "ParseRecord(%record)" on every record found. - "ParseRecord(%record)"
- Parses PDB records, updating the object attributes. This method is
called automatically on every database record during "Load()". - "ParseRecord0($data)"
- Parses the header record and places the parsed values into the hashref "$self->{header}".
- Returns the hash (not the hashref).
PROCEDURES
- "cp1252_to_pml()"
- An unfinished and completely nonfunctional procedure to convert
Windows-1252 characters to PML \a codes. - DO NOT USE.
- "pml_to_html($text,$filebase)"
- Takes as input a text string in Windows-1252 encoding containing PML
markup codes and returns a string with those codes converted to UTF-8
HTML. - Requires a second argument $filebase to specify the basename of the
file (or specifically, the basename of the file to which output text
will be written) so that image links can be generated correctly.
BUGS AND LIMITATIONS
- o HTML conversion doesn't handle handle the \T command used to
- indent.
- o HTML conversion may be suboptimal in many ways.
Most notably, most linebreaks are handled as <br />, and without
any heed to whether those linebreaks occur inside of some other
element. Validation is extremely unlikely.
