Scriptable Lua Site Generator

• Fix fennel's function scopes, so they can be used acros scripts
• Project site
• Template for both fennel and lua (index, single post, rss feed)
• new command that uses one of the templates
• doc command that prints out the documentation

Write your files in normal markdown or html. When a file has a *.lua.* or *.fnl.* in it's extension, it will be processed. In this casy, any <? ... ?> is interpreted as lua or fennel, depending on the double extension In markdown files, this is done by replacing any inline and block html that forms a processing instruction.

Any number or string that is returned from <? ... ?> expressions are added into the resulting file.

If a function or table is returned, this function is called after templating is done, with the entire text in the file. The resulting string from the function is then used as the new file content, or is called again if it is a function or table.

Any $...$ and $$...$$ in markdown files are interpreted as TeX math, and converted to mathml.

Any code block in markdown is highlighted using syntect. Other languages can be loaded via the config file.

Any [name].htm and [name].html files are automatically renamed to [name]/index.htm and [name]/index.html

Any *.ttf or *.otf font can be subset, by changing the extension to *.subset.ttf or *.subset.otf

The following functions and variables are available from lua and fennel:

• dev = true

  Set to true if run with the development server, set to false otherwise

• function mathml(tex, inline) end

  Compile the given tex to mathml. If inline is true, the resulting mathml is inline instead of block.

• function highlight(language, code, prefix) end

  Highlight the given code

This can all be controlled with the site.conf config file, which has the following defaults:

[build]
output = dist/
# setup = script.lua # setup script, run before processing

[ignore]
# scripts/* # files to ignore when building the site

[dev]
# not-found = 404.html # page to use as 404 when developing

[font]
subset = true # whether to subset fonts
# extra = abc # add these characters as extra to subset
