Building

You will need:

• soupault website generator, version 2.0.0 or newer
• cmark for Markdown to HTML conversion
• highlight for static syntax highlighting
• The OCaml compiler for build-time example typechecking
• GNU Make

Once you have all dependencies, run make all, the output will be in build/.

Note on cmark

cmark versions before and after 0.29 have different HTML tag stripping behaviour and there is no set of options that can work for both.

Pre-0.29 versions would leave HTML tags alone unless run in "safe mode" (--safe).

cmark 0.29 unexpectedly made "safe mode" the new default and will remove all HTML tags unless you run it with --unsafe.

Why a locally run program working with local files would want to do that by default is beyond me. Why they didn't add a backwards-compatibility mechanism like an environment variable is also beyond me.

Anyway, the md = "cmark --unsafe" line in soupault.conf will only work with cmark >=0.29.

If you are building on a system with an older cmark version, remove --unsafe because older cmark versions do not understand that option, but neither do they need it.

Maybe I should just move to another convertor.
