Not so great things

  • It’s still in early development
  • Things are changing fast
  • It lacks features
  • Documentation

@etiene_d FOSDEM 2016

Example!

  • - /controllers/site.lua


local site = {}
 
 function site.index(page)
 local msg = “Hello World”
 page:render(‘index’, { msg = msg } )
 end
 function site.notindex(page)
 page.theme = nil
 page:write(“I’m different!”)
 end
 
 return site

slide-25

@etiene_d FOSDEM 2016

<!-- /views/site/index.lp —>
 
 
 <p> 
 A message from the server:
 <?lua page:print(msg) ?>
 <br/>
 The message again:
 <%= msg %> <!-- syntactic sugar: same thing as above —>
 </p>


Example!

<?lua@server -- Code here runs on the server ?>
 <?lua -- Same as above ?>
 <?lua@client -- Runs at the client ?>
 <?lua@both -- Runs at the server and the client ?>
 
 <?lua@both
 another_msg = “Another message”
 ?>
 <?lua page:print(another_msg) ?>
 <?lua@client
 window:alert(another_msg) 
 ?>
