Due to lack of time, I am no longer actively working on Luapress. I will happily review, merge & release pull requests.
Luapress is yet another static site generator, written in Lua, with posts in markdown. It's simple, fast and supports both plugins and templates.
Install with Luarocks:
luarocks install luapress
Create a new site in some directory (you can optionally specify --template "etlua" or --template "lhtml" to use the etlua or LHTML default template over the mustache one):
luapress init URL [--template "etlua"]
Drop Markdown files in posts/ & pages/ and build with:
luapress
Now, just upload the contents of build/ to the web.
I'm using it for my blog, Pointless Ramblings. The Luapress website itself is also powered by Luapress :).
