artagnon / clayoven, Hacker News

Clayoven is a minimalist website generator with a carefully curated set of features. It has been built at a glacial pace, over a period of seven years, as

my websiteexpanded in content. I have a spread of mathematical notes, software-related posts, and even one wider-audience article; It suffices to say that clayoven is good on all three fronts. The source files are written in “claytext”, a custom format built for elegance and speed. (****************************************Here’s an excerpt of claytext, illustrating the main features.
