If you read this, it's quite likely that you tried to design a html-page. And you probably found out that html is a very clumsy thing: No macros, no include files and several other features lacking.
And what can you do after your page is ready? View it with a browser and test-click all links? Pfuahahaha! Most browser are designed to handle as many errors as possible and display a readable page, but don't mention your errors! And link-testing is a very stupid task...
Of course, there exist several tools: You can use a C-preprocessor to define macros and include files, use WebLint as a syntax-checker, replace your special characters with recode and run a link-test-tool on your page.
So, after installing several Tools (and compilers and
interpreters), you are ready to go... and can start five
programs after a simple change to one of your pages. (Note:
People who use the C-Preprocessor are easy to identify by
the silly date format of __DATE__: who writes
Feb 23 1995 on purpose?)
So hsc tries to summarize the functionality of all these tools in one program: it performs a (small) syntax check, tests your (local) links, replaces special characters by their entities and provides a very html-like way to define macros.
Additionally, it supports several features you probably won't find in most other tools, like absolute URIs, stripping useless white-spaces and automatically setting the size-attributes for images.
hsc simply acts as a preprocessor: You give it a "extended" html-source (later in this document refered as "hsc-source") containig special commands, and hsc interprets it and produces a pure html-output as object file. This output-file can be viewed with your w3-browser.
Usually, I write my hsc-sources using a simple text-editor, maintain them in a Makefile and process them with hsc. From my point of view, this is the recommend way of using this tool.
If you just want to create your own personal homepage, write a short html-document with information about your three selfwritten freeware-proggies or somethink like that, there are probably other tools that are easier to handle and will server your needs well. But I won't prevent you from also using hsc for these task.
