HSC (HTML Sucks Completely) is a developer tool for HTML projects. It is mainly intended for creating and maintaining larger Web sites, with a focus on compact and standards-conforming code. Its source texts are HTML files that use an extended syntax allowing for macros, conditionals, variables, expressions, etc. These sources are transformed into static (X)HTML pages. HSC checks the result for many common errors such as missing end tags and nesting mistakes, both in the markup and, to a limited extent, in CSS. As a commandline tool, it can be used together with "make", and a dependency generator is included. The macro library features things like navigation menus, LaTeX-style sections, footnotes and bibliographies, semiautomatic table-based layout, and database/scripting interfaces.
HTML-TEMPLATE is a portable library for Common Lisp that can be used to fill templates with arbitrary (string) values at runtime. It is intended to be used for HTML and is loosely modeled after the HTML::Template Perl module. It translates templates into efficient closures that can be re-used as often as needed, and uses an intelligent cache mechanism that allows templates to be updated while your program is running.
The HTML::Defaultify Perl module is designed to allow CGI programmers to present forms with some fields filled in, which is handy for letting users correct bad input, show records to be edited, and much more. The main function, defaultify(), takes any block of HTML and a hash of field names and values, and returns the HTML with the form fields set to those values. Value lists for multiple same-named fields are supported, as are pages with multiple forms. Several different input formats are supported for compatibility with existing tools.
HTML::EP is a server-side embedded HTML system in the style of PHP3, that allows you to combine the full power of Perl with your HTML pages. HTML::EP runs as a separate CGI binary or (for full speed) as a mod_perl package. It includes database access via DBI, the Perl Database Interface, session support and allows quite easy extension via a modular, OO interface.
HTML::GenToc allows you to specify significant elements that will be hyperlinked to in a Table of Contents (ToC) for a given set of HTML documents. Also, it does not require said documents to be strict HTML; this makes it suitable for using with templates, included files, and meta-languages such as WML or PHP.
HTML::TagReader is a Perl module which allows you to read HTML/XML files by tag. Its package contains some application programs which are very useful for Webmasters. They all start with the prefix "tr_" to make it easy to remember their names. tr_blck is a utility to check for broken links in Web pages. tr_llnk is a utility to build tar archives. tr_xlnk can process HTML files and expand links on directories. tr_mvlnk modifies links in HTML files with Perl commands. tr_staticssi expands the SSI directives #include virtual and #exec cmd. tr_tagcontentgrep greps for a tag (e.g., "img src"). tr_imgaddsize adds "width" and "height" to "img src=...".
