Therefore, for instance, I try +not to use the GetOpt::Long module or any other perl modules. (I do however +use HTML::TokeParser.) I also have tried to keep all the MODES of +parsing inside this file. Therefore, format_TAG subroutines are fairly +lengthy with their conditional logic. A more "elegant" solution might +be to dynamically register the parsing mode and subroutines, or maybe even work +with stylesheets. However, in order to make this the installation back-bone +of choice, there are advantages for HAVING EVERYTHING IN ONE FILE. +This way, the LPML installation software does not have to rely on OTHER +installation software (a chicken versus the egg problem). Besides, I would +suggest the modes of parsing are fairly constant: install, configinstall, +build, rpm, dpkg, htmldoc, textdoc, and status. + +Another coding decision is about using a multiple pass-through approach to +parsing the lpml file. This saves memory and makes sure the server will never +be overloaded. During the first pass-through, the script gathers information +specific as to resolving what tags with what 'dist=' attributes are to be used. +During the second pass-through, the script cleans up white-space surrounding +the XML tags, and filters through the tags based on information regarding the +'dist=' attributes (information gathered in the first pass-through). +The third and final pass-through involves formatting and rendering the XML +into whatever XML mode is chosen: install, configinstall, build, rpm, dpkg, +htmldoc, textdoc, and status. + +The hierarchy mandated by the DTD does not always correspond to the hierarchy +that is sensible for a Makefile. For instance, in a Makefile it is sensible +that soft-links are installed after files. However, in an LPML document, it +is sensible that files and links be considered together and the writer of the +LPML document should be free to place things in whatever order makes best +sense in terms of LOOKING at the information. The complication that arises +is that the parser needs to have a memory for passing values from +leaves on the XML tree to higher-up branches. Currently, this memory is +hard-coded (like with the @links array), but it may benefit from a more +formal approach in the future. + +=head1 README + +This parses an LPML file to generate information useful for +source to target installation, compilation, filesystem status +checking, RPM and Debian software packaging, and documentation. + +More information on LPML is available at http://lpml.sourceforge.net. + +=head1 PREREQUISITES + +HTML::TokeParser + +=head1 COREQUISITES + +=head1 OSNAMES + +linux + +=head1 SCRIPT CATEGORIES + +UNIX/System_administration + +=head1 AUTHOR + + Scott Harrison + codeharrison@yahoo.com + +Please let me know how/if you are finding this script useful and +any/all suggestions. -Scott + +=cut
