To build & run:

Follow the build instructions in build.txt.
Gleefully run ssc. It will misbehave if you are insufficiently gleeful.

in case of bugs

This is an alpha version of ssc. It is incomplete. What is complete needs refining. The developer needs coffee.

It may contain unexpected features. If you encounter one, please help improve ssc by collecting the following information (where relevant) and forwarding it to the developer:

version of ssc (for example, 0.2.7);
precise version of the operating system;
hardware architecture and system information;
detailed description of the problem;
detailed description of the steps to recreate it;
copy of output file/s and relevant logs;
copy of pages/website being analysed;
precise command used;
configuration file/s used, if any;
any ndx file or other pre–existing file used during the run;
any known workarounds, fixes or solutions;
a video of a dance interpretation of the issue.

Email everything to mail@ssc.lu (if the collected files are more than small, please use a public fileserver and email the link). Do NOT send anything confidential. Furthermore, unless you state otherwise, we reserve the right to publish some or all of the information sent in future versions of ssc, usually in the test suite. If you have a fix, you are invited to submit a pull request on github, at https://github.com/devongarde/ssc. Thank you.

ssc can be run in a CGI environment. This is intended for use with OpenBSD’s native httpd web server. You are reminded that ssc is not production software. Do NOT expose it to untrusted data sources, such as those found on the open web.

Notes on names

recipe: a nod to Vernor Vinge’s “A Fire Upon the Deep”;
tea: without tea, nothing works; then there’s builders’ tea;
sauce: makes the dull tasty; identifies linguistically weak pedants;
toast: toasts code; i liked burnt toast;
heater: i’m not stopping now;
unii: my preferred plural of unix: to my ears, both unixes and unices sound like they sing castrato.
andor: andor sans ancienne; land of Gift (aber nicht das Gift)

Background

I have a website, arts & ego, at https://dylanharris.org/. It has approaching 60G of original content. It contains hand coded HTMLs 2 to 5. It is a complete mess. Despite a long search, I could not find any tools to properly identify its flaws. Anything I did find was at most cursory.

Then came the cow flu*.

Hence ssc is a covid project that grew out of hand.

* corvid means crow, thus covid means cow**.
** by the laws of sympathetic spelling.
